Monterey County
State of California
Monterey County is a county authority in the State of California, covering 17 regions, serving 439,035 residents. 4,066 residential solar installs are on record here. This page is the permit route for that jurisdiction: the fifteen steps from working out who has a say over an address through to permission to operate, the documents this authority publishes, and 62 answers taken from those documents and dated.

Confirm who has a say over your address
A city address is usually permitted by the city, not the county — but not always, and some authorities keep building and hand electrical to someone else. Getting this wrong costs the whole submittal, because every requirement below belongs to whoever actually holds jurisdiction. Check the overlays in the same pass: an HOA, a historic district, a windstorm certification or a system-size cap can reshape the design, and all of them are cheaper to find now than after the array is laid out.
- Is this authority the AHJ for residential solar at this address? Yes - for the unincorporated area only 95% · department page
- What does this authority permit itself, and what does it delegate? Both - HCD Building Services issues and inspects building AND electrical permits; fire-code review and the final fire inspection are delegated to the local fire protection district / CAL FIRE; planning, coastal and design review sit with HCD Planning Services 92% · fee schedule / ordinance
- Is a permit required for a residential rooftop PV system? Yes 97% · ordinance
- Is there a separate electrical permit, or is it combined? Combined - solar is permitted as a single construction permit priced from the Solar/Photovoltaic fee line; the Construction Permit Application has Building/Electrical/Plumbing/Mechanical/Grading tick-boxes on one form 85% · fee schedule
- Is a HOA or architectural approval required first? No - not by the County. County approval is not conditioned on HOA sign-off (Gov. Code 65850.5 forbids it, and Civil Code 714 limits what an HOA may impose). But a County architectural approval of its own IS commonly required: a Design Approval under MCC 20.44 (coastal) or 21.44 (inland) must be obtained before a building permit issues for property in a Design Control 'D', Site Plan Review 'S' or Visual Sensitivity 'VS' overlay - and MCC 20.44.020.C applies the D district to ALL parcels in the Big Sur Coast, Carmel and Del Monte Forest Land Use Plan areas. 88% · ordinance
- Is there a historic-district review? Yes, but only on designated parcels. MCC 21.54 (inland) / 20.54 (coastal) apply the Historic Resources 'HR' district to sites listed on the National Register, the State Historical Landmark Register or the County Register of Historic Sites, plus sites under a mutual preservation agreement. In an HR district an 'alteration' - defined to include any exterior change or modification of a structure, its exterior architectural features, surface textures and materials, and the placement of exterior objects - requires review. Separately, the Construction Permit Application Questionnaire routes any work on a 'Historical structure or a structure older than 50 years' to the Planning Department for an extra plan set. 87% · ordinance
- Is a wind or windstorm certification required? No 80% · published criteria
- Is a Specific Use Permit or Council approval ever required? Not for ordinary rooftop PV in the inland area. Discretionary approvals that can attach: (a) in the Coastal Zone, a Coastal Development Permit where MCC 20.70.120 exemptions do not apply - notably improvements to a single-family structure 'in an area designated as highly scenic in a certified land use plan', within 50 ft of a coastal bluff edge, in an ESHA, or on a beach/wetland/seaward of the mean high tide line; (b) in Big Sur, the Coastal Implementation Plan section 20.145.030 prohibits development visible within the 'Critical Viewshed' outright and requires flagged-pole staking, photographic simulation and an on-site planner investigation; (c) a Design Approval in any D/S/VS overlay and everywhere in the Big Sur Coast, Carmel and Del Monte Forest LUP areas; (d) inland Use Permits for development on slopes over 30% or ridgeline development. In the Coastal Zone the Coastal Development Permit is the equivalent of a Use Permit. 85% · certified LCP implementation plan
- Is there a system-size cap on residential generation? No zoning cap on residential generation. The only size lines are process thresholds: the county's expedited solar process covers systems of 10 kW AC or less on single-family or duplex rooftops (AB 2188); the fee schedule bands residential at 15 kW with a per-kW step above; PG&E's Standard NEM interconnection path is for systems 30 kW or less. 85% · ordinance / department page

Check who is allowed to apply
Several authorities require the electrical permit to be pulled by a licensed electrician, or require the contractor to be registered with them BEFORE applying. Registration is not same-day. This is second on the list rather than fourth because it is the step most likely to stop the job before the drawings matter.
- Who is allowed to pull the electrical permit? Either - a California-licensed B, C-46 or C-10 contractor, or the property owner as owner-builder 90% · published checklist

Build the submittal package
Almost everywhere wants a site plan, a one-line or three-line electrical diagram, equipment cut sheets with listings, and a structural attachment detail. Build it against the published checklist rather than the last jurisdiction you worked in — the checklist is what the reviewer marks against.
- What documents make up a complete submittal? Per the Photovoltaic Submittal Checklist: cover sheet with owner name/address, scope of work and project data (APN, building use, number of PV arrays); four required plan notes (conformance with CEC Art. 690; fire district performs a final fire inspection; installation by a CA-licensed B/C-46/C-10 contractor; stand-alone placard OR service/PV disconnect directory plaque); site plan; electrical single-line diagram; roof plan and partial roof framing plan with attachment/flashing details; documented cost estimate to establish valuation; structural calculations by a registered California design professional where triggered; manufacturers' specifications and installation instructions for modules, mounting systems, combiner boxes, inverters and disconnects. Ground mounts add a foundation plan with details and a soils report or modification request. SolarAPP+ route instead: the SolarAPP+ approval document and inspection checklist, then initiate the permit and pay in Accela Citizen Access. 92% · published checklist
- How many copies, and in what format? Electronic PDF via Accela Citizen Access; from 1 September 2026 through the ePermitHub Digital Plan Room - PDF only, max 500 MB per file, no encrypted/password-protected files, plans separate from supporting documents, plans in landscape, consistent sheet numbering, top-left corner of each sheet left blank for the approval stamp. Legacy paper standard (Plan Check page): drawn at 1/4 in = 1 ft 0 in, reduced to 18 x 24 in, folded to 9 x 12 in. Number of sets is not fixed - the Questionnaire attached to the Construction Permit Application adds one extra set per outside reviewer triggered (Environmental Health, Environmental Services, Fire, Planning, MPWMD). 85% · department page
- Is a site plan required, and what must it show? Yes. PV checklist: site plan with property boundaries and north arrow, clearly identifying the location of the PV installation, and showing the electrical service, combiner box, inverter, AC and DC disconnects, junction boxes and battery banks. Ground-mounted systems must additionally show all structures on the property, site topography, driveway access from the street, easements, site utilities and the septic system with leach lines. The general Site Plan Requirements handout adds minimum scale 1 in = 40 ft, owner and preparer names, APN, 5 ft contour intervals, drainage direction, wells within 100 ft, setbacks, lot size, lot coverage and floor area ratio. 93% · published checklist
- Is a one-line / three-line diagram required? Yes 95% · published checklist
- Are string and conductor calculations required? Yes - conductor and conduit sizing must be shown; module Voc and Isc must be identified; total system kVA and the main breaker / PV breaker / bus rating at the point of interconnection must be given 88% · published checklist
- Is a structural PE stamp required, and at what threshold? Not required if the county's published Structural Criteria for Residential Flush-Mounted Solar Arrays are all met: single roof with no reroof overlay, modules parallel to the roof plane, 2-10 in gap under the modules, no overhang past ridges/hips/gable ends/eaves, array plus supports no more than 4 psf (5 psf for solar thermal), array covering no more than half the total roof area, anchor horizontal spacing within Table 1, and 5/16 in lag screws with 2.5 in embedment (or the manufacturer's fastener guidance). If ANY item is 'no', project-specific drawings and calculations stamped and signed by a California-licensed civil or structural engineer are required. The PV Submittal Checklist states the trigger differently: structural calculations by a registered California design professional if the total PV weight exceeds 5 psf OR the maximum height above the roof surface exceeds 18 in. 88% · published criteria
- Is an electrical PE stamp required, and at what threshold? No specific electrical PE threshold is published for residential PV. The Electrical Permit Submittal Requirements handout states generally that 'Plans that require calculations and or specifications are required to be wet stamped and signed by a licensed preparer', and that handout is scoped to 400 A service panels or larger. 70% · department handout

Apply and pay
Most authorities now take the whole application through a portal, and several states cap or constrain what a residential solar permit may cost. Check whether plan check is billed separately before you quote the job.
- Which permit portal does this authority use? Accela Citizen Access (aca.accela.com/monterey) is the primary portal. SolarAPP+ is used for automated code-compliance review of eligible residential rooftop retrofit PV, with the permit then initiated and paid in Citizen Access. From 1 September 2026 plan review runs through the ePermitHub Digital Plan Room, integrated into Accela. QLess (kiosk.us1.qless.com/kiosk/app/home/20438) is used to join the counter queue. 95% · portal landing page
- Can the whole application be completed online? Yes 92% · portal landing page
- What does a residential solar permit cost? USD 428 base for a residential roof-mounted system up to 15 kW, plus USD 15 for each additional kW above 15 kW. SolarAPP+ route: USD 446 each. Ground-mounted residential: USD 995 up to 15 kW plus USD 15/kW above. Residential battery / energy storage system: USD 1,224 per battery. Add surcharges: General Plan Management Fee 15% of permit fee, Technology Fee 13% of permit fee, CBSC and Strong Motion Instrumentation state surcharges, and a 2.38% credit-card pass-through. 95% · fee schedule
- How is the fee calculated? Tiered - flat base to 15 kW then per kW above (roof-mount residential: flat 428 to 15 kW, then 15 per kW). Not valuation-based. 93% · fee schedule
- Is there a separate plan-check fee? No - not for solar. The Solar/Photovoltaic fee lines are single flat amounts; the 65%-of-inspection-fee Single Family Residential Plan Check line applies to the valuation-based construction table, not to the flat solar lines. Hourly re-review is USD 220/hr and plan review not otherwise specified is USD 215/hr if a job falls outside the schedule. 78% · fee schedule

Plan review — and start the utility in parallel
Interconnection is a separate process from the permit and usually the longer pole. Where the utility does not depend on the permit being issued, running both at once is the single biggest saving available on a residential job.
- What is the stated plan-review turnaround? Expedited small residential rooftop PV: over the counter, or within 1 business day - submittals in by 12 pm are usually processed the same day, after 12 pm the next business day. Systems not qualifying for expedited review: 15 to 20 business days per the Permit Fees & Types page. The Building FAQ contradicts this and says plan check is currently 6 to 8 weeks. 85% · department page
- How long is an issued permit valid before it expires? 365 days. MCC 18.01.050.D replaces CBC 105.5: a permit becomes invalid if work is not commenced within one year of issuance, or if work is suspended or abandoned for one year - and work counts as suspended/abandoned if no required county inspection has been performed and recorded in that year. The Building Official may grant one or more written extensions of up to one year each, requested in writing before expiry with justifiable cause; a fee applies (Permit Extension USD 416). Separately, an APPLICATION expires 365 days after filing if no permit has issued (MCC 18.01.050.C). 93% · ordinance
- Which utility handles interconnection here? Pacific Gas and Electric Company (PG&E) - wires, metering and interconnection. Central Coast Community Energy (3CE) is the default community choice aggregator for generation only and plays no part in interconnection. 93% · CCA program page
- Where does the utility sit in the sequence? Parallel, with a hard dependency at the end. PG&E advises the contractor to file the Interconnection Application early so generation can start shortly after the local inspection passes. PG&E will not issue Permission to Operate until it receives the Interconnection Application, a single-line diagram and a copy of the signed-off final building permit. PTO then typically takes 5-10 business days, up to a maximum of 30. 92% · utility DG process page
28 questions answered against Monterey County’s own published documents
Q1 Is this authority the AHJ for residential solar at this address? Core Jurisdiction & scope
Yes - for the unincorporated area only
Why the confidence is not higherMonterey County Housing and Community Development (HCD), Building Services, reviews plans and inspects construction in unincorporated Monterey County; MCC Title 18 adopts the building standards codes county-wide for the unincorporated area. The 12 incorporated cities (Salinas, Monterey, Carmel-by-the-Sea, Seaside, Marina, Pacific Grove, Del Rey Oaks, Sand City, Gonzales, Soledad, Greenfield, King City) are their own AHJs.
department page checked 2026-08-28 https://www.countyofmonterey.gov/government/departments-a-h/housing-community-development/development-services/building-services
Q2 What does this authority permit itself, and what does it delegate? Core Jurisdiction & scope
Both - HCD Building Services issues and inspects building AND electrical permits; fire-code review and the final fire inspection are delegated to the local fire protection district / CAL FIRE; planning, coastal and design review sit with HCD Planning Services
Why the confidence is not higherThe brief's department name is right for this county: building and electrical both sit inside HCD (Development Services > Building Services), not Public Works. The 2026 Building fee schedule (Article XIX) carries Electrical Fees and Solar/Photovoltaic lines under the same Building Services article. The split is with fire: the PV Submittal Checklist requires the plan note 'The Fire District/Department shall perform a final fire inspection', and the county Inspection Guide says the local fire district final must be completed BEFORE the Building Services final. The Construction Permit Application routing slip lists 16 separate fire districts/CAL FIRE units that a permit may be routed to.

Q3 Is a permit required for a residential rooftop PV system? Core Jurisdiction & scope
Yes
Why the confidence is not higherMCC 18.01.050 (Ord. 5442, 9 Dec 2025) replaces CBC 105.2 and lists the county's exempt work; solar PV is not exempt. The county publishes a Photovoltaic Submittal Checklist, a Solar/Photovoltaic fee line and a SolarAPP+ route, all of which presuppose a permit.
ordinance checked 2026-08-28 https://library.municode.com/ca/monterey_county/codes/code_of_ordinances?nodeId=TIT18BUCO_CH18.01SCAD
Q4 Is there a separate electrical permit, or is it combined? Core Jurisdiction & scope
Combined - solar is permitted as a single construction permit priced from the Solar/Photovoltaic fee line; the Construction Permit Application has Building/Electrical/Plumbing/Mechanical/Grading tick-boxes on one form
Why the confidence is not higherThe 2026 Building fee schedule prices residential roof-mounted PV as one flat permit fee (not a building fee plus a separate electrical fee). Batteries/ESS and EV chargers are separately priced lines under Electrical Fees, so an added battery adds a fee even on the same job.

Q5 Who is allowed to pull the electrical permit? Core Who may apply
Either - a California-licensed B, C-46 or C-10 contractor, or the property owner as owner-builder
Why the confidence is not higherThe Photovoltaic Submittal Checklist requires the plan note 'Installation shall be provided by a California Licensed Contractor (B, C-46 or C-10)'. The Permit Fees & Types page states a building permit will be issued to 'A property owner, for work conducted on a single-family residence or duplex residence', and the Construction Permit Application has an OWNER-BUILDER applicant box with an Owner-Builder Disclosure form on the Forms page.

Q6 Must the contractor be registered with this authority before applying? Core Who may apply
No
Why the confidence is not higherNo contractor-registration step is published anywhere in the HCD Permit Center, Building Services, Forms & Applications or Online Permit Information pages; the Construction Permit Application asks only for CSLB licence number and type. The only registration mentioned is (a) an Accela Citizen Access account to file online and (b) registering as an approved solar contractor with SolarAPP+ itself, which is NREL's system, not the county's.

Q7 Is a homeowner permitted to self-install and self-permit? Who may apply
Yes
Why the confidence is not higherPermit Fees & Types states a building permit will be issued to a property owner for work on a single-family or duplex residence; the Forms page publishes 'Owner Builder Notice Information' and an 'Owner-Builder Disclosure Webform', and the FAQ tells owner-builders to tick the owner/builder verification box on the plan-check checklist. Note the PV checklist plan note still calls for a licensed B/C-46/C-10 contractor, so an owner-builder submittal will need that note reconciled at the counter.
department page checked 2026-08-28 https://www.countyofmonterey.gov/government/departments-a-h/housing-community-development/permit-center/permits-fees-types
Q8 What documents make up a complete submittal? Core Submittal package
Per the Photovoltaic Submittal Checklist: cover sheet with owner name/address, scope of work and project data (APN, building use, number of PV arrays); four required plan notes (conformance with CEC Art. 690; fire district performs a final fire inspection; installation by a CA-licensed B/C-46/C-10 contractor; stand-alone placard OR service/PV disconnect directory plaque); site plan; electrical single-line diagram; roof plan and partial roof framing plan with attachment/flashing details; documented cost estimate to establish valuation; structural calculations by a registered California design professional where triggered; manufacturers' specifications and installation instructions for modules, mounting systems, combiner boxes, inverters and disconnects. Ground mounts add a foundation plan with details and a soils report or modification request. SolarAPP+ route instead: the SolarAPP+ approval document and inspection checklist, then initiate the permit and pay in Accela Citizen Access.
Why the confidence is not higherTwo parallel routes are published. The checklist is detailed but stale in its code citations. Handout staleness: the county's own PV Submittal Checklist cites 'CRC Section 908' and the Inspection Guide for PV Systems (doc 5444) states all CEC/CRC/CBC/CFC references are to the 2013 editions, citing dead sections CFC 605.11.x, CRC R331.x, CBC 1509.7 and naming the abolished 'RMA-Building Services'. The adopted ordinance (Ord. 5442, 9 Dec 2025) is current: 2025 CBC/CRC/CFC/CEC, CFC 1205/1206/1207.

Q9 How many copies, and in what format? Submittal package
Electronic PDF via Accela Citizen Access; from 1 September 2026 through the ePermitHub Digital Plan Room - PDF only, max 500 MB per file, no encrypted/password-protected files, plans separate from supporting documents, plans in landscape, consistent sheet numbering, top-left corner of each sheet left blank for the approval stamp. Legacy paper standard (Plan Check page): drawn at 1/4 in = 1 ft 0 in, reduced to 18 x 24 in, folded to 9 x 12 in. Number of sets is not fixed - the Questionnaire attached to the Construction Permit Application adds one extra set per outside reviewer triggered (Environmental Health, Environmental Services, Fire, Planning, MPWMD).
Why the confidence is not higherThe county has never published a fixed copy count; the Plan Check page says the number 'varies' and to ask the Permit Center. The Questionnaire is the mechanism that determines it. Solar on a parcel with a septic system trips Environmental Health question 1, which names 'solar panels' explicitly and adds a set.

Q10 Is a site plan required, and what must it show? Core Submittal package
Yes. PV checklist: site plan with property boundaries and north arrow, clearly identifying the location of the PV installation, and showing the electrical service, combiner box, inverter, AC and DC disconnects, junction boxes and battery banks. Ground-mounted systems must additionally show all structures on the property, site topography, driveway access from the street, easements, site utilities and the septic system with leach lines. The general Site Plan Requirements handout adds minimum scale 1 in = 40 ft, owner and preparer names, APN, 5 ft contour intervals, drainage direction, wells within 100 ft, setbacks, lot size, lot coverage and floor area ratio.
Why the confidence is not higherTwo published documents combine. The ground-mount list is materially heavier than the rooftop list.

Yes - conductor and conduit sizing must be shown; module Voc and Isc must be identified; total system kVA and the main breaker / PV breaker / bus rating at the point of interconnection must be given
Why the confidence is not higherPV Submittal Checklist requires 'Indicate type and size of all conduit and conductors throughout the PV system', 'Identify DC array solar panel Voc and Isc rating on plans', and details of main breaker, PV breaker and rating of bussing at the point of interconnection - i.e. the 705.12 busbar calculation must be shown. String-count calculations are not separately demanded but follow from Voc.

Q13 Is a structural PE stamp required, and at what threshold? Core Engineering & stamps
Not required if the county's published Structural Criteria for Residential Flush-Mounted Solar Arrays are all met: single roof with no reroof overlay, modules parallel to the roof plane, 2-10 in gap under the modules, no overhang past ridges/hips/gable ends/eaves, array plus supports no more than 4 psf (5 psf for solar thermal), array covering no more than half the total roof area, anchor horizontal spacing within Table 1, and 5/16 in lag screws with 2.5 in embedment (or the manufacturer's fastener guidance). If ANY item is 'no', project-specific drawings and calculations stamped and signed by a California-licensed civil or structural engineer are required. The PV Submittal Checklist states the trigger differently: structural calculations by a registered California design professional if the total PV weight exceeds 5 psf OR the maximum height above the roof surface exceeds 18 in.
Why the confidence is not higherThe two published thresholds disagree (4 psf on the Structural Criteria page, 5 psf on the PV checklist). Both are county-published and current on the site; assume the stricter 4 psf for flush-mounted PV. Note the county's own coastal wind check: 'Is the dwelling farther than 200 yards from the ocean or large coastal bay?' - a 'no' pushes Big Sur, Carmel Highlands and Del Monte Forest jobs into engineered calculations.
published criteria checked 2026-08-28 https://www.countyofmonterey.gov/government/departments-a-h/housing-community-development/permit-center/permits-fees-types/structural-criteria-solar
Q14 Is an electrical PE stamp required, and at what threshold? Engineering & stamps
No specific electrical PE threshold is published for residential PV. The Electrical Permit Submittal Requirements handout states generally that 'Plans that require calculations and or specifications are required to be wet stamped and signed by a licensed preparer', and that handout is scoped to 400 A service panels or larger.
Why the confidence is not higherLooked in the Electrical Permit Submittal Requirements handout, the PV Submittal Checklist, the Minimum Plan Check Submittal Checklist and MCC 18.01.060 (Submittal Documents). None sets an electrical PE stamp threshold for a residential PV system; the PV checklist asks for a stamp only for the structural calculations.

Q15 What does a residential solar permit cost? Core Fees
USD 428 base for a residential roof-mounted system up to 15 kW, plus USD 15 for each additional kW above 15 kW. SolarAPP+ route: USD 446 each. Ground-mounted residential: USD 995 up to 15 kW plus USD 15/kW above. Residential battery / energy storage system: USD 1,224 per battery. Add surcharges: General Plan Management Fee 15% of permit fee, Technology Fee 13% of permit fee, CBSC and Strong Motion Instrumentation state surcharges, and a 2.38% credit-card pass-through.
Why the confidence is not higher2026 Adopted Building Fee schedule, Article XIX, per Resolution No. 26-017 adopted 3 February 2026 by the Board of Supervisors, in effect 4 April 2026. The 428 base sits just under the Gov. Code 66015 cap of 450 + 15/kW above 15 kW - and the per-kW step matches the statutory 15/kW exactly. But the 28% of local surcharges on top (about 120 on a 428 permit) plus state surcharges takes the out-of-door cost to roughly 550, which is worth flagging against the 66015 cap. The SolarAPP+ line at 446 is dearer than the counter route at 428.

Q16 How is the fee calculated? Core Fees
Tiered - flat base to 15 kW then per kW above (roof-mount residential: flat 428 to 15 kW, then 15 per kW). Not valuation-based.
Why the confidence is not higherFee schedule prices Solar/Photovoltaic on its own kW-banded lines, separate from the valuation-based Single Family Residential building-inspection table. This is consistent with Gov. Code 65850.55, which forbids valuation-based solar fees. Note the PV Submittal Checklist still asks for a 'Documented cost estimate to establish valuation' - a leftover from the pre-65850.55 process.
fee schedule checked 2026-08-28 https://www.countyofmonterey.gov/home/showpublisheddocument/145366/639107181008070000
Q17 Is there a separate plan-check fee? Fees
No - not for solar. The Solar/Photovoltaic fee lines are single flat amounts; the 65%-of-inspection-fee Single Family Residential Plan Check line applies to the valuation-based construction table, not to the flat solar lines. Hourly re-review is USD 220/hr and plan review not otherwise specified is USD 215/hr if a job falls outside the schedule.
Why the confidence is not higherRead the whole Article XIX schedule; the Solar/Photovoltaic block sits under its own heading with no companion plan-check percentage. Confirm at the counter for ground mounts, which may attract Environmental Services review at USD 217/hr if grading or a soils report is triggered.

Q18 What is the stated plan-review turnaround? Core Timeline & validity
Expedited small residential rooftop PV: over the counter, or within 1 business day - submittals in by 12 pm are usually processed the same day, after 12 pm the next business day. Systems not qualifying for expedited review: 15 to 20 business days per the Permit Fees & Types page. The Building FAQ contradicts this and says plan check is currently 6 to 8 weeks.
Why the confidence is not higherTwo live county pages give different standard-plan-check figures. The 15-20 business day figure is on the Permit Fees & Types page in the Expedited Solar Permits section; the 6-8 week figure is the answer to 'How long should I expect the plan check process to take?' on the Building & Planning Services FAQ and reads as the more recently updated one ('We are working to reduce the plan check time'). The expedited/SolarAPP+ figure is the one that matters for ordinary rooftop retrofit.

Q19 How long is an issued permit valid before it expires? Timeline & validity
365 days. MCC 18.01.050.D replaces CBC 105.5: a permit becomes invalid if work is not commenced within one year of issuance, or if work is suspended or abandoned for one year - and work counts as suspended/abandoned if no required county inspection has been performed and recorded in that year. The Building Official may grant one or more written extensions of up to one year each, requested in writing before expiry with justifiable cause; a fee applies (Permit Extension USD 416). Separately, an APPLICATION expires 365 days after filing if no permit has issued (MCC 18.01.050.C).
Why the confidence is not higherOrd. No. 5442, section 3, adopted 9 December 2025. The FAQ states it more bluntly: 'Construction Permits Expire if it has been 365 days since the last inspection', with a one-time 365-day extension on written request.

Q20 Which permit portal does this authority use? Core Portal & process
Accela Citizen Access (aca.accela.com/monterey) is the primary portal. SolarAPP+ is used for automated code-compliance review of eligible residential rooftop retrofit PV, with the permit then initiated and paid in Citizen Access. From 1 September 2026 plan review runs through the ePermitHub Digital Plan Room, integrated into Accela. QLess (kiosk.us1.qless.com/kiosk/app/home/20438) is used to join the counter queue.
Why the confidence is not higherThe county both offers SolarAPP+ and has a published process for it, satisfying Gov. Code 65850.52 (SB 379). Note the ePermitHub cutover date is three days after this check - projects filed either side of 1 Sep 2026 will see different submittal mechanics.

Q21 Can the whole application be completed online? Core Portal & process
Yes
Why the confidence is not higherOnline Permit Information lists 'Roof-mounted Solar Permits' among the application types that can be submitted through Accela Citizen Access, alongside online payment (card or e-check) and online inspection scheduling. The SolarAPP+ page describes an end-to-end online path: register with SolarAPP+, submit for automated review, download the approval document and inspection checklist, initiate the permit and pay in Citizen Access, then request inspection in Citizen Access.

Q22 Which utility handles interconnection here? Core Utility interconnection
Pacific Gas and Electric Company (PG&E) - wires, metering and interconnection. Central Coast Community Energy (3CE) is the default community choice aggregator for generation only and plays no part in interconnection.
Why the confidence is not higher3CE's own Solar Billing Plan page states that customers are billed by PG&E or SCE for transmission and distribution, that 3CE 'does not accept direct bill payments', and that customers have two true-ups - one with the investor-owned utility for T&D and one with 3CE for generation. Interconnection agreements and Permission to Operate are PG&E's, under CPUC Electric Rule 21.
CCA program page checked 2026-08-28 https://3cenergy.org/solar-billing-plan/
Q23 Where does the utility sit in the sequence? Core Utility interconnection
Parallel, with a hard dependency at the end. PG&E advises the contractor to file the Interconnection Application early so generation can start shortly after the local inspection passes. PG&E will not issue Permission to Operate until it receives the Interconnection Application, a single-line diagram and a copy of the signed-off final building permit. PTO then typically takes 5-10 business days, up to a maximum of 30.
Why the confidence is not higherPG&E's Getting Started with Solar page, Steps 2, 4 and 5. The final-permit scan must show the AHJ name, site address, permit number, APN, description of work and the date the city/county inspector signed off (PG&E NEM2 Final Inspection Clearance FAQ).

Q24 Is a HOA or architectural approval required first? Overlays & special cases
No - not by the County. County approval is not conditioned on HOA sign-off (Gov. Code 65850.5 forbids it, and Civil Code 714 limits what an HOA may impose). But a County architectural approval of its own IS commonly required: a Design Approval under MCC 20.44 (coastal) or 21.44 (inland) must be obtained before a building permit issues for property in a Design Control 'D', Site Plan Review 'S' or Visual Sensitivity 'VS' overlay - and MCC 20.44.020.C applies the D district to ALL parcels in the Big Sur Coast, Carmel and Del Monte Forest Land Use Plan areas.
Why the confidence is not higherThis is the Monterey-specific answer to the coastal question in the brief. The county's own Permit Fees & Types page lists 'Any other exterior change, such as change of window, type, size or location' among the works needing Design Approval in a D district, and adds 'projects which do not require a building permit may require Design Approval'. Over-the-counter and administrative Design Approvals exist (separate coastal and inland request forms), so it is not automatically a hearing.

Q25 Is there a historic-district review? Overlays & special cases
Yes, but only on designated parcels. MCC 21.54 (inland) / 20.54 (coastal) apply the Historic Resources 'HR' district to sites listed on the National Register, the State Historical Landmark Register or the County Register of Historic Sites, plus sites under a mutual preservation agreement. In an HR district an 'alteration' - defined to include any exterior change or modification of a structure, its exterior architectural features, surface textures and materials, and the placement of exterior objects - requires review. Separately, the Construction Permit Application Questionnaire routes any work on a 'Historical structure or a structure older than 50 years' to the Planning Department for an extra plan set.
Why the confidence is not higherThe 50-year trigger on the application questionnaire catches far more houses than the HR district does, and it is a routing trigger rather than a discretionary permit trigger.

Q26 Is a wind or windstorm certification required? Overlays & special cases
No
Why the confidence is not higherNo wind or windstorm certification is required. California has no TDI-equivalent. Wind is handled inside the structural check: the county's Structural Criteria worksheet asks whether the dwelling is farther than 200 yards from the ocean or a large coastal bay and sets Exposure B/C assumptions and design wind speeds behind Table 1; failing any item pushes the job to engineered calculations rather than to a certification. Looked in MCC 18.02/18.02.5 local amendments and the Structural Criteria page.

Q27 Is a Specific Use Permit or Council approval ever required? Overlays & special cases
Not for ordinary rooftop PV in the inland area. Discretionary approvals that can attach: (a) in the Coastal Zone, a Coastal Development Permit where MCC 20.70.120 exemptions do not apply - notably improvements to a single-family structure 'in an area designated as highly scenic in a certified land use plan', within 50 ft of a coastal bluff edge, in an ESHA, or on a beach/wetland/seaward of the mean high tide line; (b) in Big Sur, the Coastal Implementation Plan section 20.145.030 prohibits development visible within the 'Critical Viewshed' outright and requires flagged-pole staking, photographic simulation and an on-site planner investigation; (c) a Design Approval in any D/S/VS overlay and everywhere in the Big Sur Coast, Carmel and Del Monte Forest LUP areas; (d) inland Use Permits for development on slopes over 30% or ridgeline development. In the Coastal Zone the Coastal Development Permit is the equivalent of a Use Permit.
Why the confidence is not higherThis is the finding the brief asked for, and Monterey differs from San Luis Obispo: the coastal layer here can reach a ROOF-MOUNTED array, not only ground mounts. Big Sur CIP 20.145.030 defines development within the critical viewshed as anything 'visible from Highway 1, including pull-outs, right-of-ways, and walkways at the highways edge', judged on normal unaided vision, in any direction, at any season, under existing conditions with no credit for future screening - and prohibits it. The same section requires 'Roof and surface treatments, colors and materials ... natural and earth tone', and bars 'structural additions, antennae, exterior lighting, or other improvements in view of Highway 1 ... without separate permit consideration'. Controls run on both Big Sur documents: 'viewshed' 73 hits in the LUP and 63 in the CIP, 'zzqqx' 0 - and 'solar' and 'photovoltaic' are 0 hits in BOTH, so there is no solar-specific carve-out either way; the general viewshed rule is what applies. There is unresolved tension between this and Gov. Code 65850.5, which requires administrative non-discretionary review of small residential rooftop PV; the Coastal Act is not obviously subordinated to it. Treat any Big Sur / Carmel Highlands / Del Monte Forest rooftop job as needing a coastal determination under MCC 20.70.115 before assuming a ministerial permit.

Q28 Is there a system-size cap on residential generation? Overlays & special cases
No zoning cap on residential generation. The only size lines are process thresholds: the county's expedited solar process covers systems of 10 kW AC or less on single-family or duplex rooftops (AB 2188); the fee schedule bands residential at 15 kW with a per-kW step above; PG&E's Standard NEM interconnection path is for systems 30 kW or less.
Why the confidence is not higherRan solar/photovoltaic searches across MCC Title 20 Chapter 20.64 (Special Regulations, 188,858 chars) and Title 21 Chapter 21.64 (Special Regulations, 165,400 chars): 0 hits for 'solar' and 0 for 'photovolt' in both, with positive control 'tree' at 13 and 59 hits and fabricated control 'zzqqx' at 0 in both - so the absence is real, not a broken search. Title 20 Chapter 20.70 (Coastal Development Permits) likewise: 0 solar hits, 'exempt' 10 hits as positive control.

Build to the code editions actually in force here
The NEC edition a jurisdiction enforces is often a cycle behind the newest one published, and local amendments sit on top of it. Rapid shutdown, conductor sizing and labelling all change between editions, so the edition in force is the first thing to establish, not the last.
- Which NEC edition is in force? 2023 - via the 2025 California Electrical Code (Title 24 Part 3), adopted by MCC 18.03.010 (Ord. No. 5442, 9 Dec 2025) 92% · adopting ordinance
- Which building code edition is in force? 2025 California Building Code and 2025 California Residential Code (Title 24 Parts 2 and 2.5, based on the 2024 IBC/IRC), adopted by MCC 18.02 and 18.02.5 per Ord. No. 5442, adopted 9 December 2025. CRC adopted excluding Chapter 1 and including Appendices H, Q and X. 95% · adopting ordinance
- Which fire code edition is in force? 2025 California Fire Code (Title 24 Part 9, based on the 2024 IFC), including Appendices B, BB, C, CC and H, adopted by MCC 18.09.010 (Ord. No. 5442, section 11, 9 Dec 2025); MCC 18.09.030.A further replaces CFC 101.2.1 so that ALL appendices to the 2025 CFC are adopted in their entirety. 95% · adopting ordinance
- Are there local amendments to any of the above? Yes - substantial, and several are solar-specific. MCC 18.09.030 amends CFC 1205 (solar signage and roof access), 1206 (fuel cells) and 1207 (energy storage); MCC 18.02.5.040 replaces CRC R902.1.3 to require a minimum Class B fire-retardant roof covering county-wide; MCC 18.01.050 rewrites CBC 105.2/105.3.2/105.5 (permit exemptions and expiry); MCC 18.02.5.060 amends CRC R403.1.3 footing reinforcement and R602.10 bracing in Seismic Design Categories D0-D2. 95% · ordinance
- What is the installation judged against?

Fire access, setbacks and pathways
Ridge setbacks and roof access pathways are fire-service requirements and they constrain the array layout. They are the most common cause of a redesign after the fire department comments on a plan set.
- What ridge setback and access pathways are required? 2025 CFC 1205.2.1 pathways and setbacks apply, WITH TWO LOCAL CHANGES: (i) MCC 18.09.030 deletes CFC 1205.2.1 Exceptions 1 and 2 in their entirety, so the state's escape hatches from the one- and two-family roof access requirements are not available in unincorporated Monterey County; (ii) MCC 18.09.030 adds CFC 1205.2.1.4 Hip and Valley Layout - modules shall be no closer than one and one-half feet (18 in) to a hip or valley where modules are placed on both sides of it; where modules are on only one side of a hip or valley of equal length, they may be placed directly adjacent to it. The county's (stale) PV Submittal Checklist additionally states 'PV panel array shall not be installed within 3 feet of all edges including the ridge line', and its Inspection Guide restates the old CFC 605.11.3 scheme: 3 ft eave-to-ridge pathway on each hip-roof slope, two 3 ft pathways per slope on single-ridge roofs, and modules no higher than 3 ft below the ridge for smoke ventilation. 92% · fire code local amendment

Rapid shutdown
Which rapid-shutdown rule applies follows directly from the NEC edition in force, and the initiation device has to be at a location the fire service can reach and identify. This is inspected, and it is labelled.
- Is rapid shutdown required, and to which NEC edition? Yes - NEC 690.12 rapid shutdown as published in the 2023 NEC / 2025 California Electrical Code, adopted with no California amendment and no Monterey County amendment. 88% · adopting ordinance

Labels and placards
The NEC sets a baseline for permanent markings at the service equipment and the disconnecting means. On top of that, an authority may specify its own wording, and the utility may specify more again. Where any of them writes its own text, a generic off-the-shelf label set will not pass — this is the detail most often fixed on a return visit.
- Which placards does this authority require at the service equipment? Local, in MCC 18.09.030 amending CFC 1205.1 to add 1205.1.1 Signing and Marking, 'in addition to signing and marking requirements of the California Building Code and the California Residential Code': (1) 1205.1.1.1 Main Panel Exterior Marking - a placard permanently affixed to the MAIN SERVICE DISCONNECT PANEL reading SOLAR DISCONNECT INSIDE PANEL. (2) 1205.1.1.2 Circuit Disconnecting Means Marking - a permanent label adjacent to the circuit breaker controlling the inverter or other PV system electrical controller, reading SOLAR DISCONNECT. (3) 1205.1.1.3 Secondary Power Sources - where PV is interconnected to battery systems, generator backup or other secondary power systems, additional signage acceptable to the fire code official indicating the location of the secondary power source shutoff switch. (4) 1205.1.1.4 Installer Information - signage acceptable to the fire code official giving the name and emergency telephone number of the installing contractor, adjacent to the main disconnect. For ESS, MCC 18.09.030 adds CFC 1207.4.8-6: BESS in block letters 6 in high with a 3/4 in stroke on a contrasting background, plus 1207.4.1.1 requiring ESS disconnects at or adjacent to the main electrical panel with placarding showing equipment location and all shutdowns. For fuel cells, CFC 1206.14: FUEL CELL in block letters 6 in high with a 3/4 in stroke on a contrasting background. All of this is on top of the standard CEC 690.13/690.53/690.54/705.10 and 690.31(E) WARNING: PHOTOVOLTAIC POWER SOURCE labelling. 95% · fire code local amendment
- Does the authority specify placard wording of its own? Yes 97% · fire code local amendment
- Does it specify letter height, colour or material? Yes, in detail. Main panel placard (CFC 1205.1.1.1 as amended): RED, with WHITE CAPITAL letters at least 1/2 in high in a NON-SERIF font, constructed of weather-resistant durable plastic with ENGRAVED letters or other approved material. Inverter-breaker label (1205.1.1.2): CONTRASTING COLOUR capital letters at least 3/8 in high in a non-serif font, constructed of durable adhesive material or other approved material. BESS and FUEL CELL placards (1207.4.8-6 and 1206.14): block letters 6 in high with a 3/4 in stroke on a contrasting background. The county's PV Submittal Checklist separately calls for signage detail on the plans: 'green or red plastic engraved with 1/2 inch high white letters, permanently mounted on or immediately next to the panel door.' 95% · fire code local amendment
- Is a site plan / facility map placard required, and what must it show? Yes in two places. (a) AHJ: the PV Submittal Checklist requires a plan note that 'Buildings with utility services and a PV system shall have a plaque or directory indicating the location of the service disconnecting means and the PV system disconnecting means' (stand-alone systems instead get a placard stating it is a stand-alone system and showing the disconnect location) - this is CEC 690.56(B)/705.10, posted at the electrical service and at the PV inverter if not co-located. (b) UTILITY: PG&E requires a SITE MAP PLACARD wherever an AC disconnect is installed more than 10 ft from the PG&E electric meter, and where more than one AC disconnect is installed each must be labelled '1 of x, 2 of x'. 90% · utility DG manual / checklist
- Does the UTILITY specify placards beyond the AHJ's? Yes. PG&E AC Disconnect & Variance Requirements: an AC disconnect and signage are required on ALL non-inverter-based generators; and for inverter-based systems an AC disconnect is triggered by a line-side (above main breaker) connection, three-phase at the service point, a transformer-rated meter panel, a meter panel rated over 320 A, or meter types CL020/CL400/CL480 and all K-based meters. Where triggered: install a FUSIBLE AC disconnect within 10 ft of the PG&E electric meter; where more than one AC disconnect is installed, label them '1 of x, 2 of x'; where any AC disconnect is more than 10 ft from the PG&E meter, install a SITE MAP PLACARD and a variance is required. 90% · utility DG manual
- Where must the labels be placed? County: the SOLAR DISCONNECT INSIDE PANEL placard permanently affixed to the main service disconnect panel (exterior); the SOLAR DISCONNECT label adjacent to the circuit breaker controlling the inverter; installing-contractor name and emergency number adjacent to the main disconnect; secondary-power shutoff location signage where batteries/generators are present; ESS disconnects at or adjacent to the main electrical panel with placarding; BESS/FUEL CELL placards where those systems are inside a structure. CEC-driven: WARNING: PHOTOVOLTAIC POWER SOURCE markings on DC conduit, raceways, cable assemblies, enclosures, junction and combiner boxes and disconnects - every 10 ft, within 1 ft of turns and bends, and within 1 ft above and below roof/ceiling, wall and barrier penetrations - and a marking adjacent to the main service disconnect clearly visible from where the disconnect is operated. Utility: fusible AC disconnect within 10 ft of the PG&E meter where required; site map placard where it is not. 92% · fire code local amendment / inspection guide

Disconnect, storage and listed equipment
Where the AC disconnect must sit relative to the meter is usually the utility's rule, not the building department's. Battery storage frequently carries its own permit, its own inspection and its own fire conditions.
- Where must the AC disconnect be, relative to the meter? Where PG&E requires one, a FUSIBLE AC disconnect within 10 ft of the PG&E electric meter. If the AC disconnect is more than 10 ft from the PG&E meter, a site map placard must be installed AND a variance is required from PG&E. Where more than one AC disconnect is installed, each must be labelled '1 of x, 2 of x'. An AC disconnect and signage are required on all non-inverter-based generators; for inverter-based systems the triggers are a line-side connection above the main breaker, three-phase at the service point, a transformer-rated meter panel, a meter panel rated over 320 A, or meter types CL020/CL400/CL480 and all K-based meters. Otherwise no separate utility AC disconnect is required and no variance is needed. The county adds nothing of its own on disconnect location beyond CEC 690.13/690.15 and the requirement that the plans identify the service disconnecting means and PV disconnect locations and that inverter disconnects be a separate serviceable component. 90% · utility DG manual
- Must equipment be on a specific approved list? Yes in substance. Equipment must be listed and labelled for the application - DC modules to UL 1703, AC modules to UL 1703 and UL 1741, combiner boxes to UL 1741, grid-tied inverters marked 'utility interactive', DC overcurrent devices listed for DC operation - and installed per the listed manufacturer's instructions. The county requires manufacturers' specifications and installation instructions for all modules, mounting systems, combiner boxes, inverters and disconnects with the submittal. Systems routed through SolarAPP+ must use equipment present in the SolarAPP+ equipment database; PG&E's online interconnection tool offers an 'approved equipment listing from drop-down menus' and inverters must meet Rule 21 smart-inverter requirements. There is no separate Monterey County approved-products list. 85% · inspection guide / checklist
- Are batteries permitted, and under what conditions? Yes. Batteries are permitted under 2025 CFC Chapter 12 as adopted, with Monterey County additions: MCC 18.09.030 adds CFC 1207.4.1.1 requiring ESS disconnects to be located at or adjacent to the main electrical panel with appropriate placarding showing the location of equipment and all shutdowns; and CFC 1207.4.8-6 requiring, where a battery energy storage system is installed INSIDE any structure, signage acceptable to the fire code official indicating its location plus a placard reading BESS in 6 in block letters with a 3/4 in stroke on a contrasting background. Where PV is interconnected to a battery system, CFC 1205.1.1.3 additionally requires signage showing the secondary power source shutoff location. Fee: USD 1,224 per battery. On a commercial property, ground or roof mount solar using batteries also routes to the Environmental Health Bureau for review. 92% · fire code local amendment / fee schedule
- Is there a separate ESS permit or inspection? Yes in effect - a separate priced permit line. The 2026 fee schedule charges 'Residential Battery / Energy Storage System' at USD 1,224 PER BATTERY under Electrical Fees, entirely separate from the Solar/Photovoltaic lines, so adding storage to a PV job adds its own fee and its own scope. It is normally taken on the same construction permit rather than a wholly separate application, and the fire code official's acceptance of the ESS signage is a distinct sign-off. 80% · fee schedule
- Is a ground mount treated as a structure? Yes 90% · published checklist / fee schedule
- Is there a local rule on service upgrades or busbar sizing? No local amendment to service or busbar sizing. Judged against CEC 705.12(B)(3). The county's PV checklist requires the point of interconnection, main breaker, PV breaker and bus rating to be shown on the plans, and its Inspection Guide checks that the inverter output breaker sits at the opposite end of the bus from the utility supply unless the sum of the inverter and utility breakers is within the panelboard bus rating. Related fee lines: panel replacement/service under 400 A USD 441, 400 A or larger USD 1,409. 83% · ordinance / checklist
- Is a specific mounting system or attachment spacing required? Yes - the county publishes prescriptive mounting criteria for residential flush-mounted arrays: modules parallel to the roof plane, a 2 in to 10 in gap between the underside of the module and the roof surface, no overhang past any roof edge (ridge, hip, gable end, eave), array plus supports no heavier than 4 psf (5 psf solar thermal), array covering no more than half of the total roof area, anchor horizontal spacing within Table 1, staggered anchors permitted at up to twice the Table 1 spacing but never more than 6 ft 0 in, manufactured plated wood trusses at flat to 6:12 limited to 4 ft 0 in horizontal anchor spacing with staggered adjacent rows, and 5/16 in lag screws with 2.5 in embedment into the rafter (or the manufacturer's fastener guidance).

Q29 Which NEC edition is in force? Core Code editions in force
2023 - via the 2025 California Electrical Code (Title 24 Part 3), adopted by MCC 18.03.010 (Ord. No. 5442, 9 Dec 2025)
Why the confidence is not higherIMPORTANT DEFECT IN THE ORDINANCE TEXT: MCC 18.03.010 adopts 'the 2025 California Electrical Code ... which is based on the 2020 National Electrical Code with applicable amendments from the State of California, Annexes C and D of the 2023 National Electrical Code'. The 2025 CEC is based on the 2023 NEC, not the 2020 - the '2020' is a copy-paste survival from the previous (2022 CEC / Ord. 5389) cycle, and the same sentence then correctly cites the 2023 NEC annexes. The state edition governs regardless under H&SC 18938(b): NEC Article 690 applies as published in the 2025 CEC with zero California amendment. Do not let the ordinance's '2020' wording be read as a local rollback.

Why the confidence is not higherEach chapter carries an 'Applicability of local amendments' section stating that notwithstanding anything in the 2025 state code to the contrary, the local amendments apply. Worth noting against the state baseline: Ord. 5442 was adopted 9 December 2025, i.e. AFTER AB 130 (Stats. 2025 Ch. 22) froze more-restrictive residential building standards from 1 October 2025. The county has nonetheless adopted residential-reaching amendments (Class B roofs, deleted CFC 1205.2.1 exceptions). Whether those survive an AB 130 challenge is not something the county has published a finding on - but they are what Building Services will inspect against.

Q33 What is the installation judged against? Core Electrical
The 2025 California Electrical Code (2023 NEC) Article 690 and Article 705, plus MCC Chapter 18.03 and the solar amendments to CFC Chapter 12 in MCC 18.09.030. The PV Submittal Checklist requires the plan note 'The installation of the PV system shall conform to the requirements of the California Electrical Code, Article 690 and any other applicable articles or standards.'
Why the confidence is not higherMCC 18.03.030 is a one-line section that exists only to push solar back to the fire-code amendments - so the electrical chapter itself adds nothing to Article 690 beyond signage/roof-access via CFC 1205.

Q34 Is there a local rule on service upgrades or busbar sizing? Electrical
No local amendment to service or busbar sizing. Judged against CEC 705.12(B)(3). The county's PV checklist requires the point of interconnection, main breaker, PV breaker and bus rating to be shown on the plans, and its Inspection Guide checks that the inverter output breaker sits at the opposite end of the bus from the utility supply unless the sum of the inverter and utility breakers is within the panelboard bus rating. Related fee lines: panel replacement/service under 400 A USD 441, 400 A or larger USD 1,409.
Why the confidence is not higherSearched MCC 18.03 (whole chapter) - the only substantive sections are Adoption, Applicability of local amendments and the one-line solar cross-reference. Nothing on services or busbars. The Electrical Permit Submittal Requirements handout is scoped to '400 Amperes Service Panel Or Larger'.

Q35 Is a specific mounting system or attachment spacing required? Structural & mounting
Yes - the county publishes prescriptive mounting criteria for residential flush-mounted arrays: modules parallel to the roof plane, a 2 in to 10 in gap between the underside of the module and the roof surface, no overhang past any roof edge (ridge, hip, gable end, eave), array plus supports no heavier than 4 psf (5 psf solar thermal), array covering no more than half of the total roof area, anchor horizontal spacing within Table 1, staggered anchors permitted at up to twice the Table 1 spacing but never more than 6 ft 0 in, manufactured plated wood trusses at flat to 6:12 limited to 4 ft 0 in horizontal anchor spacing with staggered adjacent rows, and 5/16 in lag screws with 2.5 in embedment into the rafter (or the manufacturer's fastener guidance). Roof sheathing at least 7/16 in OSB or plywood; 1x skip sheathing acceptable. Mean roof height not greater than 40 ft.
Why the confidence is not higherStructural Criteria - Solar page. Derived from the California Solar Permitting Guidebook structural appendix but published as county criteria; the PV checklist separately requires 'Details indicating attachment of PV modules to roof framing. Verify method of waterproofing and flashing.'

Q36 What ridge setback and access pathways are required? Core Fire pathways & setbacks
2025 CFC 1205.2.1 pathways and setbacks apply, WITH TWO LOCAL CHANGES: (i) MCC 18.09.030 deletes CFC 1205.2.1 Exceptions 1 and 2 in their entirety, so the state's escape hatches from the one- and two-family roof access requirements are not available in unincorporated Monterey County; (ii) MCC 18.09.030 adds CFC 1205.2.1.4 Hip and Valley Layout - modules shall be no closer than one and one-half feet (18 in) to a hip or valley where modules are placed on both sides of it; where modules are on only one side of a hip or valley of equal length, they may be placed directly adjacent to it. The county's (stale) PV Submittal Checklist additionally states 'PV panel array shall not be installed within 3 feet of all edges including the ridge line', and its Inspection Guide restates the old CFC 605.11.3 scheme: 3 ft eave-to-ridge pathway on each hip-roof slope, two 3 ft pathways per slope on single-ridge roofs, and modules no higher than 3 ft below the ridge for smoke ventilation.
Why the confidence is not higherThe DELETION of Exceptions 1 and 2 is the load-bearing local fact and is easy to miss - it makes Monterey stricter than the state baseline on roof access for ordinary houses. Handout staleness: the county's own PV Submittal Checklist cites 'CRC Section 908' and the Inspection Guide for PV Systems (doc 5444) states all CEC/CRC/CBC/CFC references are to the 2013 editions, citing dead sections CFC 605.11.x, CRC R331.x, CBC 1509.7 and naming the abolished 'RMA-Building Services'. The adopted ordinance (Ord. 5442, 9 Dec 2025) is current: 2025 CBC/CRC/CFC/CEC, CFC 1205/1206/1207.

Q37 Is rapid shutdown required, and to which NEC edition? Core Rapid shutdown
Yes - NEC 690.12 rapid shutdown as published in the 2023 NEC / 2025 California Electrical Code, adopted with no California amendment and no Monterey County amendment.
Why the confidence is not higherMCC 18.03 adds nothing to Article 690. Caution: the ordinance's own adoption sentence miscalls the 2025 CEC 'based on the 2020 National Electrical Code' (see q29) - if anyone quotes that to argue for 2020 NEC 690.12 module-level requirements, the state edition still governs under H&SC 18938(b). The county's published Inspection Guide is 2013-vintage and does not mention rapid shutdown at all. Handout staleness: the county's own PV Submittal Checklist cites 'CRC Section 908' and the Inspection Guide for PV Systems (doc 5444) states all CEC/CRC/CBC/CFC references are to the 2013 editions, citing dead sections CFC 605.11.x, CRC R331.x, CBC 1509.7 and naming the abolished 'RMA-Building Services'. The adopted ordinance (Ord. 5442, 9 Dec 2025) is current: 2025 CBC/CRC/CFC/CEC, CFC 1205/1206/1207.

Q38 Which placards does this authority require at the service equipment? Core Labels Signage & labelling
Local, in MCC 18.09.030 amending CFC 1205.1 to add 1205.1.1 Signing and Marking, 'in addition to signing and marking requirements of the California Building Code and the California Residential Code': (1) 1205.1.1.1 Main Panel Exterior Marking - a placard permanently affixed to the MAIN SERVICE DISCONNECT PANEL reading SOLAR DISCONNECT INSIDE PANEL. (2) 1205.1.1.2 Circuit Disconnecting Means Marking - a permanent label adjacent to the circuit breaker controlling the inverter or other PV system electrical controller, reading SOLAR DISCONNECT. (3) 1205.1.1.3 Secondary Power Sources - where PV is interconnected to battery systems, generator backup or other secondary power systems, additional signage acceptable to the fire code official indicating the location of the secondary power source shutoff switch. (4) 1205.1.1.4 Installer Information - signage acceptable to the fire code official giving the name and emergency telephone number of the installing contractor, adjacent to the main disconnect. For ESS, MCC 18.09.030 adds CFC 1207.4.8-6: BESS in block letters 6 in high with a 3/4 in stroke on a contrasting background, plus 1207.4.1.1 requiring ESS disconnects at or adjacent to the main electrical panel with placarding showing equipment location and all shutdowns. For fuel cells, CFC 1206.14: FUEL CELL in block letters 6 in high with a 3/4 in stroke on a contrasting background. All of this is on top of the standard CEC 690.13/690.53/690.54/705.10 and 690.31(E) WARNING: PHOTOVOLTAIC POWER SOURCE labelling.
Why the confidence is not higherThis is a genuine, current, county-specific placard specification adopted 9 December 2025 and correctly numbered to the 2025 CFC (1205/1206/1207, not the dead 1204/605.11). It is the single most consequential installation finding for this authority.

Q39 Does the authority specify placard wording of its own? Core Labels Signage & labelling
Yes
Why the confidence is not higherMCC 18.09.030 prescribes exact wording: SOLAR DISCONNECT INSIDE PANEL (main service disconnect panel), SOLAR DISCONNECT (adjacent to the inverter breaker), BESS (battery energy storage inside a structure), FUEL CELL (stationary fuel cell inside a structure). Secondary-power and installer-contact signage wording is left to the fire code official's acceptance rather than fixed.

Q40 Does it specify letter height, colour or material? Core Labels Signage & labelling
Yes, in detail. Main panel placard (CFC 1205.1.1.1 as amended): RED, with WHITE CAPITAL letters at least 1/2 in high in a NON-SERIF font, constructed of weather-resistant durable plastic with ENGRAVED letters or other approved material. Inverter-breaker label (1205.1.1.2): CONTRASTING COLOUR capital letters at least 3/8 in high in a non-serif font, constructed of durable adhesive material or other approved material. BESS and FUEL CELL placards (1207.4.8-6 and 1206.14): block letters 6 in high with a 3/4 in stroke on a contrasting background. The county's PV Submittal Checklist separately calls for signage detail on the plans: 'green or red plastic engraved with 1/2 inch high white letters, permanently mounted on or immediately next to the panel door.'
Why the confidence is not higherNote the conflict: the ordinance says RED only for the main placard; the older PV Submittal Checklist says 'green or red'. The ordinance is the December 2025 enactment and should govern - assume red. Both specify 1/2 in white engraved lettering, so the two agree on everything else.

Q41 Is a site plan / facility map placard required, and what must it show? Core Labels Signage & labelling
Yes in two places. (a) AHJ: the PV Submittal Checklist requires a plan note that 'Buildings with utility services and a PV system shall have a plaque or directory indicating the location of the service disconnecting means and the PV system disconnecting means' (stand-alone systems instead get a placard stating it is a stand-alone system and showing the disconnect location) - this is CEC 690.56(B)/705.10, posted at the electrical service and at the PV inverter if not co-located. (b) UTILITY: PG&E requires a SITE MAP PLACARD wherever an AC disconnect is installed more than 10 ft from the PG&E electric meter, and where more than one AC disconnect is installed each must be labelled '1 of x, 2 of x'.
Why the confidence is not higherThe county's own site-plan requirement for the permit drawing (location of electrical service, combiner box, inverter, AC and DC disconnects, junction boxes and battery banks) is effectively the source data for the PG&E site map placard.
utility DG manual / checklist checked 2026-08-28 https://www.pge.com/assets/pge/docs/about/doing-business-with-pge/ac-disconnect-variance-requirements.pdf
Q42 Does the UTILITY specify placards beyond the AHJ's? Core Labels Signage & labelling
Yes. PG&E AC Disconnect & Variance Requirements: an AC disconnect and signage are required on ALL non-inverter-based generators; and for inverter-based systems an AC disconnect is triggered by a line-side (above main breaker) connection, three-phase at the service point, a transformer-rated meter panel, a meter panel rated over 320 A, or meter types CL020/CL400/CL480 and all K-based meters. Where triggered: install a FUSIBLE AC disconnect within 10 ft of the PG&E electric meter; where more than one AC disconnect is installed, label them '1 of x, 2 of x'; where any AC disconnect is more than 10 ft from the PG&E meter, install a SITE MAP PLACARD and a variance is required.
Why the confidence is not higherThis is a PG&E requirement independent of and additional to the county's CFC 1205.1.1 placards, and the distance rule is measured from the PG&E METER, not the main panel. The interconnection application asks explicitly for 'Distance of AC Disconnect from main service panel (if AC Disconnect is installed)'.
utility DG manual checked 2026-08-28 https://www.pge.com/assets/pge/docs/about/doing-business-with-pge/ac-disconnect-variance-requirements.pdf
Q43 Where must the labels be placed? Core Labels Signage & labelling
County: the SOLAR DISCONNECT INSIDE PANEL placard permanently affixed to the main service disconnect panel (exterior); the SOLAR DISCONNECT label adjacent to the circuit breaker controlling the inverter; installing-contractor name and emergency number adjacent to the main disconnect; secondary-power shutoff location signage where batteries/generators are present; ESS disconnects at or adjacent to the main electrical panel with placarding; BESS/FUEL CELL placards where those systems are inside a structure. CEC-driven: WARNING: PHOTOVOLTAIC POWER SOURCE markings on DC conduit, raceways, cable assemblies, enclosures, junction and combiner boxes and disconnects - every 10 ft, within 1 ft of turns and bends, and within 1 ft above and below roof/ceiling, wall and barrier penetrations - and a marking adjacent to the main service disconnect clearly visible from where the disconnect is operated. Utility: fusible AC disconnect within 10 ft of the PG&E meter where required; site map placard where it is not.
Why the confidence is not higherPlacement detail for the marking interval and the 'clearly visible from where the disconnect is operated' rule comes from the county's Inspection Guide, which cites the dead CFC 605.11.1.3/605.11.1.4 and CRC R331.2.3/R331.2.4 - the substance survives in the 2023 NEC 690.31 and 2025 CFC 1205. Handout staleness: the county's own PV Submittal Checklist cites 'CRC Section 908' and the Inspection Guide for PV Systems (doc 5444) states all CEC/CRC/CBC/CFC references are to the 2013 editions, citing dead sections CFC 605.11.x, CRC R331.x, CBC 1509.7 and naming the abolished 'RMA-Building Services'. The adopted ordinance (Ord. 5442, 9 Dec 2025) is current: 2025 CBC/CRC/CFC/CEC, CFC 1205/1206/1207.

Q44 Must equipment be on a specific approved list? Equipment listing
Yes in substance. Equipment must be listed and labelled for the application - DC modules to UL 1703, AC modules to UL 1703 and UL 1741, combiner boxes to UL 1741, grid-tied inverters marked 'utility interactive', DC overcurrent devices listed for DC operation - and installed per the listed manufacturer's instructions. The county requires manufacturers' specifications and installation instructions for all modules, mounting systems, combiner boxes, inverters and disconnects with the submittal. Systems routed through SolarAPP+ must use equipment present in the SolarAPP+ equipment database; PG&E's online interconnection tool offers an 'approved equipment listing from drop-down menus' and inverters must meet Rule 21 smart-inverter requirements. There is no separate Monterey County approved-products list.
Why the confidence is not higherNo county-maintained list exists; the constraint is listing plus the SolarAPP+ and PG&E databases.

Q45 Are batteries permitted, and under what conditions? Core Battery / ESS
Yes. Batteries are permitted under 2025 CFC Chapter 12 as adopted, with Monterey County additions: MCC 18.09.030 adds CFC 1207.4.1.1 requiring ESS disconnects to be located at or adjacent to the main electrical panel with appropriate placarding showing the location of equipment and all shutdowns; and CFC 1207.4.8-6 requiring, where a battery energy storage system is installed INSIDE any structure, signage acceptable to the fire code official indicating its location plus a placard reading BESS in 6 in block letters with a 3/4 in stroke on a contrasting background. Where PV is interconnected to a battery system, CFC 1205.1.1.3 additionally requires signage showing the secondary power source shutoff location. Fee: USD 1,224 per battery. On a commercial property, ground or roof mount solar using batteries also routes to the Environmental Health Bureau for review.
Why the confidence is not higherThe ESS-disconnect-at-the-main-panel rule is a genuine local siting constraint, not just signage - it constrains where a battery's disconnecting means may go.

Q46 Is there a separate ESS permit or inspection? Battery / ESS
Yes in effect - a separate priced permit line. The 2026 fee schedule charges 'Residential Battery / Energy Storage System' at USD 1,224 PER BATTERY under Electrical Fees, entirely separate from the Solar/Photovoltaic lines, so adding storage to a PV job adds its own fee and its own scope. It is normally taken on the same construction permit rather than a wholly separate application, and the fire code official's acceptance of the ESS signage is a distinct sign-off.
Why the confidence is not higherThe county publishes no standalone ESS permit application; the separateness is visible in the fee schedule and in the distinct CFC 1207 local amendments. Confirm at the counter whether a storage-only retrofit is filed as an electrical permit.

Q47 Is a ground mount treated as a structure? Core Ground mount
Yes
Why the confidence is not higherGround mounts are priced as a separate and much dearer permit (residential ground-mounted USD 995 to 15 kW versus USD 428 roof-mounted), and the PV Submittal Checklist demands a Foundation Plan with foundation details cross-referenced to applicable details, and 'Soils report required or modification request submitted', plus a far heavier site plan showing all structures on the property, topography, driveway access from the street, easements, site utilities and the septic system with leach lines. Ground mounts also fall outside the flush-mounted Structural Criteria entirely, and outside SolarAPP+ (roof-mounted retrofit only). In the Coastal Zone a ground mount is far more likely to need a Coastal Development Permit than a rooftop array.
published checklist / fee schedule checked 2026-08-28 https://www.countyofmonterey.gov/government/departments-a-h/housing-community-development/permit-center/forms-applications/photovoltaic-submittal-checklist-13299
Q48 Where must the AC disconnect be, relative to the meter? Core Utility equipment
Where PG&E requires one, a FUSIBLE AC disconnect within 10 ft of the PG&E electric meter. If the AC disconnect is more than 10 ft from the PG&E meter, a site map placard must be installed AND a variance is required from PG&E. Where more than one AC disconnect is installed, each must be labelled '1 of x, 2 of x'. An AC disconnect and signage are required on all non-inverter-based generators; for inverter-based systems the triggers are a line-side connection above the main breaker, three-phase at the service point, a transformer-rated meter panel, a meter panel rated over 320 A, or meter types CL020/CL400/CL480 and all K-based meters. Otherwise no separate utility AC disconnect is required and no variance is needed. The county adds nothing of its own on disconnect location beyond CEC 690.13/690.15 and the requirement that the plans identify the service disconnecting means and PV disconnect locations and that inverter disconnects be a separate serviceable component.
Why the confidence is not higherPG&E AC Disconnect & Variance Requirements decision flow. The distance is measured from the PG&E METER, not the main service panel - a common error.

Book it
Booking is a portal, a phone call or an email depending on the authority, and the notice required is rarely zero. Book before the work is finished rather than after — the lead time, not the work, is usually what sets the date.
- How is an inspection booked? Portal or Phone - Accela Citizen Access (aca.accela.com/monterey) online, or telephone (831) 755-5025 92% · department page
- How much notice is required? 1 business day. For inland South County and the Big Sur coastal area the Building Inspections page is explicit: call HCD at (831) 755-5025 before 3:30 pm on the day PRIOR to the requested inspection. 82% · department page
- Are same-day or AM/PM windows offered? No. The FAQ states plainly that specific requests for morning or afternoon inspections cannot be taken and that inspection times are not set until the morning of the inspection date. You may call between 8:00 am and 8:15 am on the day of inspection for an estimated time of arrival; inspectors are generally reachable by phone 8:00-8:15 am and 3:30-4:00 pm daily. South County inland and Big Sur coastal areas are served on Mondays, Wednesdays and Fridays only. 90% · department page

Know who turns up
Some authorities inspect their own solar work; some delegate it, and a few do not inspect the PV equipment itself at all. Who is coming determines what they will look at.
- Does this AHJ perform its own final solar inspection? Yes - HCD Building Services inspectors perform the building/electrical final. The FIRE final is delegated to the local fire protection district or CAL FIRE unit and must be completed FIRST. 90% · inspection guide
- If delegated, to whom? The local fire protection district or CAL FIRE unit for the parcel, for the fire final only. Districts named by the county: Aromas Tri-County, Cachagua, CAL FIRE Coastal, CAL FIRE South County, CAL FIRE Central Valley, Carmel Valley FPD, Carmel Highlands & Cypress FPD, Gonzales Rural, Greenfield FPD, Mission Soledad Rural, Monterey County Regional Fire District, North County FPD, Pebble Beach CSD. Look the district up in Citizen Access under 'Lookup Property Information' or call (831) 755-5027. 88% · inspection guide
-
Work the stages in order
A rough-in or mid-roof inspection, where one is required, has to happen before the work it covers is closed up. Missing a stage means opening something back up, and it is the most expensive kind of correction.
- Which inspections are required, and in what order? For a rooftop retrofit: local fire district final fire inspection, then the HCD Building Services building/electrical final. Planning/coastal condition compliance (where a Design Approval or Coastal permit applied) and Environmental Health (where the parcel has a septic system) must also sign off before Building Services will 'final' the permit. For a ground mount, add a foundation inspection before concrete placement, and potentially grading/erosion-control inspections. 85% · department page
- Is a rough-in or mid-roof inspection required? No for a rooftop retrofit - a single final is the norm, consistent with Gov. Code 65850.5 which allows only one inspection for eligible small residential rooftop PV, and with the SolarAPP+ flow which goes straight from permit issuance to 'Schedule Inspection'. Yes for a ground mount, which needs a foundation inspection before concrete is poured. 78% · department page / statute
-
Have the paperwork on site
The approved plan set, the permit, and the equipment listings should be on site and reachable. Inspectors routinely verify that installed equipment matches what was approved, and that the labels are the ones the plan set promised.
- Is there a published inspection checklist? Yes - 'Inspection Guide for PV Systems in One- and Two-Family Dwellings (For Rooftop Photovoltaic Systems meeting the Standard Plan)', a 19-item single-page field checklist plus a comprehensive reference of roughly 70 items with a signage requirements table. SolarAPP+ projects additionally download a SolarAPP+ inspection checklist with the approval document. 85% · inspection guide
- What must be on site at inspection? The JOB CARD and the APPROVED PLANS, in a dry, accessible place at the job site. If either is missing when the inspector arrives the inspection is rescheduled. For SolarAPP+ jobs, the SolarAPP+ approval document and inspection checklist downloaded at approval. Any deviation from the approved plans may require an approved plan revision before the next inspection. 92% · department page
- Does the inspector verify labels and listings? Yes 92% · inspection guide
-
Sign-off, and permission to operate
Passing gives you a final or an equivalent sign-off. That is not the same as permission to operate: PTO comes from the utility, and who tells the utility the inspection passed varies. A system left switched off for weeks is usually waiting on this handover.
- What is issued on pass? Final - the inspector signs off the job card and Building Services 'finals' the permit, once Fire, Health and Planning have given their approvals. No certificate of occupancy is issued for a PV retrofit. The signed final permit / permit cover is the document PG&E needs. 90% · department page
- Who notifies the utility for PTO? Installer - the contractor submits the final building permit, the Interconnection Application and a single-line diagram to PG&E, through the YourProjects portal for Standard NEM (under 30 kW solar and under 10 kW storage) or to NEMFollowups@pge.com if the portal cannot be used; complex systems go to the PG&E Electric Grid Interconnection representative or Rule21Gen@pge.com. PG&E then upgrades the meter and issues written Permission to Operate, typically 5-10 business days and up to 30. The County does not notify PG&E. 93% · utility DG process page
- Is there a re-inspection fee? USD 217 per hour, charged in 0.25 hour increments. Triggered where the work is not complete, the plans or job card are not at the site, the inspector's corrections have not been done, or there is no access to the inspection area. No further inspections are made until the re-inspection fee is paid and the issues resolved. Inspection outside normal business hours USD 258/hr; on a holiday USD 296/hr. Work done without a permit is charged at DOUBLE the permit fee. 93% · fee schedule
- How are corrections issued and cleared? The inspector signs the inspection record (job card) for each item inspected and approved; where an item fails, the inspector leaves a written correction notice on site. Corrections must be completed before calling for re-inspection, and a re-inspection fee may apply. If the failure involves a deviation from the approved plans, a plan revision must be submitted and approved before the next inspection - a Revision Construction Permit Application webform exists for this, charged at USD 238/hr plan check and USD 218/hr inspection. Future inspections may be denied where there are outstanding fees, unapproved plan changes, or missing special-inspection or structural-observation reports. From 1 September 2026, plan-review corrections are issued and cleared through the ePermitHub Digital Plan Room, which consolidates all comments in one place with a 'Responding to Issues' workflow. 88% · department page

No county-wide notice period is published for the Salinas Valley / Peninsula unincorporated areas; next-day is the working assumption there. Looked in the Building Inspections page, the FAQ and the Online Permit Information page.

Q51 Are same-day or AM/PM windows offered? Booking & scheduling
No. The FAQ states plainly that specific requests for morning or afternoon inspections cannot be taken and that inspection times are not set until the morning of the inspection date. You may call between 8:00 am and 8:15 am on the day of inspection for an estimated time of arrival; inspectors are generally reachable by phone 8:00-8:15 am and 3:30-4:00 pm daily. South County inland and Big Sur coastal areas are served on Mondays, Wednesdays and Fridays only.
Why the confidence is not higherTwo FAQ answers say the same thing in different words ('May I request what time of day...' and 'When will the inspector arrive?'), so this is settled county practice, not a one-off note.

Q52 Does this AHJ perform its own final solar inspection? Core Who inspects
Yes - HCD Building Services inspectors perform the building/electrical final. The FIRE final is delegated to the local fire protection district or CAL FIRE unit and must be completed FIRST.
Why the confidence is not higherThe county's Inspection Guide for PV Systems states: 'your local fire district must complete its final inspection prior to the RMA-Building Services final inspection', with a contact list of 16 districts and instructions to look up the district in Citizen Access or call (831) 755-5027. The PV Submittal Checklist requires the same as a plan note. The Building Inspections page confirms Building Services 'finals' the permit only once Fire, Health and Planning have given their approvals.

Q53 If delegated, to whom? Core Who inspects
The local fire protection district or CAL FIRE unit for the parcel, for the fire final only. Districts named by the county: Aromas Tri-County, Cachagua, CAL FIRE Coastal, CAL FIRE South County, CAL FIRE Central Valley, Carmel Valley FPD, Carmel Highlands & Cypress FPD, Gonzales Rural, Greenfield FPD, Mission Soledad Rural, Monterey County Regional Fire District, North County FPD, Pebble Beach CSD. Look the district up in Citizen Access under 'Lookup Property Information' or call (831) 755-5027.
Why the confidence is not higherBuilding and electrical inspection is NOT delegated - only the fire final. Note the Big Sur / Carmel coastal parcels fall to CAL FIRE Coastal or Carmel Highlands & Cypress, which is a separate call from the county.

Q54 Which inspections are required, and in what order? Core Stages & sequence
For a rooftop retrofit: local fire district final fire inspection, then the HCD Building Services building/electrical final. Planning/coastal condition compliance (where a Design Approval or Coastal permit applied) and Environmental Health (where the parcel has a septic system) must also sign off before Building Services will 'final' the permit. For a ground mount, add a foundation inspection before concrete placement, and potentially grading/erosion-control inspections.
Why the confidence is not higherBuilding Inspections page: 'When all phases of construction are approved and all agencies (i.e. Fire, Health, Planning) have given their final approval, the Building Services will final the permit.' The published Typical Sequence list is for a new structure and does not cover PV; the foundation step is the applicable one for ground mounts.
department page checked 2026-08-28 https://www.countyofmonterey.gov/government/departments-a-h/housing-community-development/development-services/building-services/building-inspections
Q55 Is a rough-in or mid-roof inspection required? Stages & sequence
No for a rooftop retrofit - a single final is the norm, consistent with Gov. Code 65850.5 which allows only one inspection for eligible small residential rooftop PV, and with the SolarAPP+ flow which goes straight from permit issuance to 'Schedule Inspection'. Yes for a ground mount, which needs a foundation inspection before concrete is poured.
Why the confidence is not higherNo mid-roof or rough-in step appears anywhere in the SolarAPP+ process description, the Inspection Guide for PV Systems, or the Building Inspections typical sequence for PV. Looked in all three.

Q56 Does the inspector verify labels and listings? Core What is checked
Yes
Why the confidence is not higherThe county's Inspection Guide for PV Systems, Section 1 Field Inspection Guide, items 10 and 17: 'Equipment installed, listed and labeled according to the approved plan (e.g. PV modules, DC/DC converters, combiners, inverters, disconnects, load centers and electrical service equipment)' and 'PV system markings, labels and signs according to the approved plan.' Section 2 adds a full Signs and Labels sub-section and a signage requirements table. The CFC 1205.1.1 placards are fire-code items the fire district will look for at its own final.

Q57 Is there a published inspection checklist? Core What is checked
Yes - 'Inspection Guide for PV Systems in One- and Two-Family Dwellings (For Rooftop Photovoltaic Systems meeting the Standard Plan)', a 19-item single-page field checklist plus a comprehensive reference of roughly 70 items with a signage requirements table. SolarAPP+ projects additionally download a SolarAPP+ inspection checklist with the approval document.
Why the confidence is not higherCAVEAT, and this is the pattern in the brief: the county guide states in terms that 'All California Electrical Code (CEC), California Residential Code (CRC), California Building Code (CBC) and California Fire Code (CFC) references are to the 2013 versions unless otherwise noted', and cites CFC 605.11.x, CRC R331.x, CBC 1509.7 and CRC R908.1 throughout - all dead numbering. It also still says 'RMA-Building Services', a department abolished in the reorganisation into HCD. Worse, the Permit Fees & Types page now lists the Eligibility Checklist, Submittal Requirements, both PV Standard Plans and the Inspection Guide as PLAIN TEXT with the hyperlinks stripped - only two orphan links survive in the page HTML, and only the Inspection Guide (document 5444) and the Solar Pool Heating Inspection Guide (document 5439) are still reachable. The expedited-solar standard plans and eligibility checklist are effectively unpublished.

Q58 What must be on site at inspection? Core Documents on site
The JOB CARD and the APPROVED PLANS, in a dry, accessible place at the job site. If either is missing when the inspector arrives the inspection is rescheduled. For SolarAPP+ jobs, the SolarAPP+ approval document and inspection checklist downloaded at approval. Any deviation from the approved plans may require an approved plan revision before the next inspection.

Q59 Is there a re-inspection fee? Corrections & re-inspection
USD 217 per hour, charged in 0.25 hour increments. Triggered where the work is not complete, the plans or job card are not at the site, the inspector's corrections have not been done, or there is no access to the inspection area. No further inspections are made until the re-inspection fee is paid and the issues resolved. Inspection outside normal business hours USD 258/hr; on a holiday USD 296/hr. Work done without a permit is charged at DOUBLE the permit fee.

Q60 How are corrections issued and cleared? Corrections & re-inspection
The inspector signs the inspection record (job card) for each item inspected and approved; where an item fails, the inspector leaves a written correction notice on site. Corrections must be completed before calling for re-inspection, and a re-inspection fee may apply. If the failure involves a deviation from the approved plans, a plan revision must be submitted and approved before the next inspection - a Revision Construction Permit Application webform exists for this, charged at USD 238/hr plan check and USD 218/hr inspection. Future inspections may be denied where there are outstanding fees, unapproved plan changes, or missing special-inspection or structural-observation reports. From 1 September 2026, plan-review corrections are issued and cleared through the ePermitHub Digital Plan Room, which consolidates all comments in one place with a 'Responding to Issues' workflow.

Q61 What is issued on pass? Core Final sign-off & PTO
Final - the inspector signs off the job card and Building Services 'finals' the permit, once Fire, Health and Planning have given their approvals. No certificate of occupancy is issued for a PV retrofit. The signed final permit / permit cover is the document PG&E needs.
Why the confidence is not higherBuilding Inspections page. PG&E's NEM2 Final Inspection Clearance FAQ defines what it will accept: 'a signed building or electrical permit, which also includes the Final Permit Cover for all associated NEM2 generation by the authority having jurisdiction', showing AHJ name, site address, permit number, APN, description/summary of work and the date signed off by the city/county inspector.

Q62 Who notifies the utility for PTO? Core Final sign-off & PTO
Installer - the contractor submits the final building permit, the Interconnection Application and a single-line diagram to PG&E, through the YourProjects portal for Standard NEM (under 30 kW solar and under 10 kW storage) or to NEMFollowups@pge.com if the portal cannot be used; complex systems go to the PG&E Electric Grid Interconnection representative or Rule21Gen@pge.com. PG&E then upgrades the meter and issues written Permission to Operate, typically 5-10 business days and up to 30. The County does not notify PG&E.

Jurisdiction & key facts
The standing 62-question set, answered for Monterey County against this authority’s own published documents. Every answer carries the confidence it was recorded at and the document it came from. Where nothing is published we say so and show where we looked — a blank here is a finding, not a gap.
Jurisdiction unconfirmed
- Why not higher
- The brief's department name is CORRECT for this county, unlike Alameda: building AND electrical both sit in HCD, and HCD also holds planning, engineering and environmental services. Two corrections to note. First, HCD replaced the former Resource Management Agency (RMA), but county-published solar handouts still say 'RMA-Building Services'. Second, the coastal question in the brief resolves DIFFERENTLY here than in San Luis Obispo: Monterey's certified LCP can reach ROOF-MOUNTED PV, not only ground mounts. MCC 20.70.120.A exempts alterations and additions to existing single-family dwellings from a Coastal Development Permit, but expressly withdraws that exemption for improvements 'in an area designated as highly scenic in a certified land use plan', within 50 ft of a coastal bluff edge, or in an ESHA - and the Big Sur Coastal Implementation Plan section 20.145.030 PROHIBITS development visible within the Critical Viewshed outright, judged on unaided vision from Highway 1 under existing conditions with no credit for screening. On top of that, MCC 20.44.020.C puts every parcel in the Big Sur Coast, Carmel and Del Monte Forest Land Use Plan areas into the Design Control 'D' district, where the county's own guidance says 'any other exterior change' needs a Design Approval before a building permit issues. Neither the Big Sur LUP nor the Big Sur CIP mentions solar or photovoltaics at all (0 hits in both, controls passed), so there is no carve-out either way - the general viewshed rule is what a rooftop array meets. This sits in unresolved tension with Gov. Code 65850.5's non-discretionary review requirement.

Labels & placards for this authority
Monterey County writes its own placard wording. A standard NEC label set will not satisfy it — the exact text, and in most cases the size, colour and font, are specified below.
Wording 97%
Yes
Size, colour & material 95%
Yes, in detail. Main panel placard (CFC 1205.1.1.1 as amended): RED, with WHITE CAPITAL letters at least 1/2 in high in a NON-SERIF font, constructed of weather-resistant durable plastic with ENGRAVED letters or other approved material. Inverter-breaker label (1205.1.1.2): CONTRASTING COLOUR capital letters at least 3/8 in high in a non-serif font, constructed of durable adhesive material or other approved material. BESS and FUEL CELL placards (1207.4.8-6 and 1206.14): block letters 6 in high with a 3/4 in stroke on a contrasting background. The county's PV Submittal Checklist separately calls for signage detail on the plans: 'green or red plastic engraved with 1/2 inch high white letters, permanently mounted on or immediately next to the panel door.'
Where they go 92%
County: the SOLAR DISCONNECT INSIDE PANEL placard permanently affixed to the main service disconnect panel (exterior); the SOLAR DISCONNECT label adjacent to the circuit breaker controlling the inverter; installing-contractor name and emergency number adjacent to the main disconnect; secondary-power shutoff location signage where batteries/generators are present; ESS disconnects at or adjacent to the main electrical panel with placarding; BESS/FUEL CELL placards where those systems are inside a structure. CEC-driven: WARNING: PHOTOVOLTAIC POWER SOURCE markings on DC conduit, raceways, cable assemblies, enclosures, junction and combiner boxes and disconnects - every 10 ft, within 1 ft of turns and bends, and within 1 ft above and below roof/ceiling, wall and barrier penetrations - and a marking adjacent to the main service disconnect clearly visible from where the disconnect is operated. Utility: fusible AC disconnect within 10 ft of the PG&E meter where required; site map placard where it is not.
What the utility wants on top 90%
Yes. PG&E AC Disconnect & Variance Requirements: an AC disconnect and signage are required on ALL non-inverter-based generators; and for inverter-based systems an AC disconnect is triggered by a line-side (above main breaker) connection, three-phase at the service point, a transformer-rated meter panel, a meter panel rated over 320 A, or meter types CL020/CL400/CL480 and all K-based meters. Where triggered: install a FUSIBLE AC disconnect within 10 ft of the PG&E electric meter; where more than one AC disconnect is installed, label them '1 of x, 2 of x'; where any AC disconnect is more than 10 ft from the PG&E meter, install a SITE MAP PLACARD and a variance is required.
