City of Cerritos

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 — the City of Cerritos accepts, tracks and issues the residential solar permit at its own counter (Community Development, (562) 916-1201 / Building & Safety, (562) 916-1209), so it is the AHJ of record for the address. Building & electrical plan check/inspection are performed by LA County DPW as Cerritos is on DPW's Building & Safety 'Contract Cities' list; fire review for ESS/BIPV/disconnect placarding sits with LA County Fire. 90% · authority's own department page
• What does this authority permit itself, and what does it delegate? Delegated (for Building & Electrical) — City of Cerritos is named on LA County DPW Building & Safety Division's 'Contract Cities' list (Artesia, Carson, Cerritos, Commerce, Industry, Irwindale, La Cañada-Flintridge, Lakewood, La Mirada, Lawndale, Lomita, Rolling Hills, Rolling Hills Estates, Santa Fe Springs, Temple City, Westlake Village), meaning LA County DPW performs building & electrical plan check and inspection. Planning/zoning review is retained by the City itself. Fire review for ESS/BIPV/disconnect signage sits with LA County Fire (LACoFD). 90% · county department page
• Is a permit required for a residential rooftop PV system? Yes. Cerritos's own 'Community Development Application and Building Permit Forms' guide lists 'Solar Energy System' as a project type requiring a Solar Planning Application plus a Building/Plumbing/Electrical/Mechanical Permit Application. 92% · published checklist
• Is there a separate electrical permit, or is it combined? Combined. LA County Building Code Chapter 68 §6804: 'A combined solar energy permit may be issued for photovoltaic systems, which will include all building and electrical work,' subject to a separate plumbing permit only if plumbing work (e.g. solar thermal) is involved. 85% · county building code chapter
• Is a HOA or architectural approval required first? Not a City requirement, but a live consideration: Cerritos's own Planning-application list includes an optional 'HOA Approval Form,' implying some Cerritos HOAs' CC&Rs require notice/review before a solar permit is accepted. Any such HOA review is capped by the California Solar Rights Act (Civil Code §714/§4600), which bars an HOA from unreasonably restricting or denying a code-compliant residential solar installation. 55% · authority's own department page
• Is there a historic-district review? No historic-district review was found. Cerritos Municipal Code's title-level table of contents (Titles 1-29 plus Statutory References) contains no historic-preservation or historic-district title or chapter, consistent with Cerritos being a single-era master-planned city (incorporated 1956, built out largely in the 1960s-80s). 55% · municipal code table of contents (via Wayback)
• Is a wind or windstorm certification required? No — no wind/windstorm certification requirement (a Texas-TDI-style concept) was found anywhere in the County's residential PV structural materials; wind loading is instead handled prescriptively through the anchor-spacing/lag-screw tables in the County's Structural Criteria checklist. 70% · county structural criteria bulletin
• Is a Specific Use Permit or Council approval ever required? No SUP or Council approval was found required for a standard residential rooftop solar system — it is processed as a 'Minor'/over-the-counter Planning matter per the City's own fee schedule and forms guide, not routed to Planning Commission or City Council. 60% · fee schedule
• Is there a system-size cap on residential generation? Two different caps found and reported rather than reconciled: (1) LA County's current EPIC-LA 'Express Solar Roof Mount Residential' eligibility caps total system size (solar + ESS) at 38.4 kW AC nameplate rating, per the County's Form A affidavit (updated 9/1/23) and its December-2025 Express Permit Application Types guide; (2) the still-currently-published LA County Building Code Chapter 68 text (effective 10-01-15) defines a 'Small Residential Rooftop Solar Energy System' — the category the whole expedited chapter is built around — as ≤10 kW AC. The 38.4 kW figure is the one actually used by the live EPIC-LA Express product today; the 10 kW figure remains in the chapter's own definitions section and was not found to have been formally superseded in the chapter text itself. 85% · county building code chapter + county affidavit form

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 licensed C-10 electrician/C-46 solar contractor normally pulls it, but the County's Form B 'Affidavit for Owner-Builder' is explicitly part of the standard submittal package, so a homeowner may self-permit the electrical work. 80% · county submittal bulletin
• Must the contractor be registered with this authority before applying? No dedicated pre-registration process was found; the County/City require a current CSLB license number and class on the permit application/affidavit forms, not a separate contractor-registration step with the City or County. 55% · county application form
• Is a homeowner permitted to self-install and self-permit? Yes — via LA County's Form B 'Affidavit for Owner-Builder,' one of the three affidavit options accepted with a small-residential-rooftop-solar submittal. 80% · county submittal bulletin

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? Layered submittal: (1) City — Solar Planning Application, Building/Plumbing/Electrical/Mechanical Permit Application, Owner/Contractor Declaration Form, Waste Management Plan Form, three (3) sets of plans to Current Planning; (2) County (for the building/electrical permit) — completed permit application, eligibility checklist for expedited permitting, a completed Standard Electrical Plan (or full electrical plans if non-standard), a roof plan showing PV layout/access pathways/fire classification/label locations, completed Structural Criteria worksheet, and Form A/B/C affidavit. 88% · published checklist
• How many copies, and in what format? City: three (3) sets of plans submitted to Current Planning for the Solar Energy System application. County (Express Solar, ≤38.4 kW AC, via EPIC-LA): fully electronic, no paper copies. County (standard/non-express): submitted electronically via the County's BSOP electronic-submittal system or at the local Building & Safety office. 75% · published checklist
• Is a site plan required, and what must it show? Yes — a roof plan is required showing roof layout, PV panel locations, approximate roof-access point, code-compliant access pathways, PV system fire classification, and the location of all required labels/markings. 85% · county submittal bulletin
• Is a one-line / three-line diagram required? Yes — a completed Standard Electrical Plan (single-line diagram) is required for systems that qualify for the standard/expedited plan, or full custom electrical drawings including a single-line diagram otherwise. 82% · county eligibility checklist
• Are string and conductor calculations required? Yes — the eligibility checklist requires confirming string counts per MPPT input, fuse ratings vs. module series-fuse rating, inverter/combiner counts, and bus-bar/OCPD sizing math (sum of main + inverter OCPD ≤120% of bus rating), i.e. conductor/overcurrent calculations. 82% · county eligibility checklist
• Is a structural PE stamp required, and at what threshold? Conditional, not a flat threshold: a CA-licensed Civil or Structural Engineer's stamp is required only if any item on the County's prescriptive Structural Criteria checklist (roof slope/rafter spacing, ≤4 psf array weight, anchor spacing per Table 1, wind-uplift lag-screw spec) is answered 'No.' If all items pass, no stamp is required. 85% · county structural criteria bulletin
• Is an electrical PE stamp required, and at what threshold? Not found as a standalone requirement for standard residential PV using the County's Standard Electrical Plan — a licensed C-10/C-46 contractor's signature is what the standard-plan pathway calls for, not a PE electrical stamp. 55% · county eligibility checklist

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? Two portals depending on pathway: LA County's EPIC-LA (epicla.lacounty.gov) for the 'Residential Express Solar Roof Mount' permit — search 'Cerritos' once inside EPIC-LA to filter to City of Cerritos permits; a City-run 'Application/Plan Submittal Form' (online upload) for the standard/non-express Solar Energy System Planning + Building application, backstopped by phone/in-person at City Hall. 85% · authority's own department page
• Can the whole application be completed online? Partially — Yes for the County Express Solar Roof Mount product (EPIC-LA is a self-service online portal, semi-automated self-issuance); No/not yet for the standard City-processed Solar Energy System Planning+Building path, where the City's own banner states 'This fall, the City will launch a new, full-service online permitting and approval system' — i.e. as of the date checked, the City-wide digital system had not yet gone live. 75% · authority's own department page
• What does a residential solar permit cost? Layered: City Planning fee $360 (residential) per the City's current Master Fee Schedule; City Building & Safety issuance fee $45 (single permit) or $102 (multiple linked permits); County building+electrical combined permit fee computed by declared valuation off the County's Valuation Fee Table, which LA County Building Code §6805 caps at $500 combined for a small residential rooftop PV system 'unless modified by or in accordance with Government Code Section 66015 or other applicable law.' If ESS/BIPV triggers LA County Fire review, add LACoFD Appendix QQ fees: $776 plan review + $293 field inspection (Photovoltaic residential) and/or $195 plan review (Energy storage system, Group R-3/R-4). 80% · fee schedule
• How is the fee calculated? Tiered/valuation, not per-kW or per-panel: the City's Planning fee is a flat tier ($360 residential vs $454 non-residential); the County's building+electrical permit fee scales with declared project valuation off a published Valuation Fee Table, subject to the $500 combined statutory cap noted above. 78% · fee schedule
• Is there a separate plan-check fee? Yes — the County's Building Valuation Fee Table lists 'P.C. Fee' (plan-check) and 'Permit Fee' as two separate columns for every valuation tier; a note also sets a $218.17 minimum plan-check fee for a Standard Plan submittal. LACoFD's Appendix QQ likewise separates plan review from field inspection. 85% · fee schedule

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? 1 to 3 business days for the County's small residential rooftop solar plan review (per Chapter 68 §6803: 'plan check review will be completed within one to three business days' of a complete application). No separate turnaround figure was found published for the City's own Planning-Division review step. 70% · county building code chapter
• Which utility handles interconnection here? Southern California Edison (SCE). The City's own 'Cerritos Electric Utility' (CEU) page names SCE directly, stating CEU is a commercial/industrial-only generation program ('Businesses interested in CEU service...') and that 'SCE will continue to transmit the electricity' even for CEU customers — meaning SCE remains the interconnecting/distribution utility, and residential customers (not eligible for CEU) stay with SCE for both distribution and default generation. 90% · authority's own department page
• Where does the utility sit in the sequence? Not confirmed from a Cerritos- or SCE-specific document for the sequence; based on standard California NEM/Rule 21 practice (and consistent with q62's finding that the installer submits proof of final inspection to the utility) the utility interconnection agreement is typically processed in parallel with permitting and finalized after permit-final, i.e. 'After permit.' 50% · utility page (dead link, noted)

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 82% · board letter / adopting ordinance
• Which building code edition is in force? 2025 California Building Code, adopted with LA County local amendments as LA County Code Title 26 (per the Nov 2025 Board of Supervisors letter proposing the 2026 code-adoption ordinances). 80% · board letter / adopting ordinance
• Which fire code edition is in force? 2023 LACFC (2022 California Fire Code plus LA County local amendments, codified as LACC Title 32) is the edition confirmed in the most recent LACoFD documents found — the Sept-2023 ESS/PV/Disconnects guide and the Fire-Code fee schedule (Appendix QQ, 'Ordinances #23-0008 & 2023-0058... effective 2024-01-11') both cite the 2023 LACFC. I did not find confirmation that Fire (Title 32) was included in the same November-2025 Board letter that proposes 2025-cycle Building/Electrical/Plumbing/Mechanical/Residential/Green/Existing-Building codes, so the Fire Code cycle may currently lag the other Title 24 codes. 70% · fire department guidance document
• Are there local amendments to any of the above? Yes. LA County has extensive local amendments to the state codes for solar specifically: Building Code Chapter 68 (expedited residential rooftop solar permitting, fee cap, inspection rules) and LA County Fire Code Title 32 Sections 509, 1207.11.x (ESS location/energy-rating/disconnect-placarding amendments to the base CFC), among others referenced throughout LACoFD's ESS/PV/Disconnects guide. 88% · county building code chapter
• What is the installation judged against? The current 2025 California Electrical/Building/Residential Codes as locally amended by LA County (Title 26/27/30), plus LA County Building Code Chapter 68's solar-specific procedural rules and LA County Fire Code (Title 32) Sections 509 and 1207.11.x for ESS/disconnect/placarding. 78% · county affidavit / adopting ordinance

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? Not independently confirmed against the current 2023 LACFC pathway/setback sections themselves (I did not retrieve the LACFC's own Section 1204/1205 fire-pathway text). The only pathway guidance I could confirm is a reference, inside the County's 2016-dated Attachment A submittal bulletin, to the State Fire Marshal's 'Solar PV Installation Guide' for pathway examples — that OSFM document is the older (pre-2019) guideline the research brief specifically warns about, so I am not relying on it for current ridge-setback figures. 45% · county submittal bulletin (flagged as possibly stale)

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, rapid shutdown is required — the currently adopted electrical code is the 2023 NEC (via the 2025 CEC), which carries NEC 690.12 module-level rapid-shutdown requirements. Flag: LA County's own BCM 6807 labeling package (dated 2015-16) predates this — its 'Solar PV Standard Plan' labels cite only CEC 690.35(F), 690.5(C), 690.17, 690.53/690.54 and 705.12 (the pre-690.12 ungrounded-system/array-boundary labeling scheme) and never mention 690.12 or 'rapid shutdown' by name. LACoFD's separate Sept-2023 Disconnect Placarding guide (Appendix B), by contrast, explicitly defines and requires placarding for 'Rapid Shutdown (RSD)' initiation devices, so the current, in-force placarding requirement does account for 690.12 even though the older Building-and-Safety labeling bulletin does not. 55% · fire department guidance document (current) vs county building bulletin (stale, both cited)

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? Two layers: (1) Standard NEC/CEC 690 & 705 markings (per the County's — dated — Standard Plan): PV System AC Disconnect and DC Disconnect labels with voltage/current ratings, a 'Dual Power Sources' warning at the main panel, an inverter-output-connection warning, and (where applicable) an ungrounded-conductor shock-hazard warning. (2) LA County Fire Department's own current 'Electrical Power Source Disconnect Placarding System' (Sept 2023, still cited as current in later dated fire documents): an exterior placard at every disconnect/panel that must be operated to fully de-energize the structure, plus panel-interior placards identifying specific breakers, whenever a dwelling is wired for more than one power source (which any grid-tied PV system is). 75% · fire department guidance document
• Does the authority specify placard wording of its own? Yes — LACoFD specifies exact placard verbiage: exterior placards read 'F.D. – ELECTRICAL BLDG DISCONNECT / #X of Y'; panel-interior placards identify individual switch numbers. The older County electrical-label sheet also specifies verbatim NEC/CEC warning-label wording (e.g. 'WARNING PHOTOVOLTAIC POWER SOURCE', 'WARNING DUAL POWER SOURCES...'). 85% · fire department guidance document
• Does it specify letter height, colour or material? Yes, precisely specified by LACoFD: Exterior placards — minimum 2" tall × 3.5" wide, weather-resistant plastic, verbiage engraved, red letters on a yellow background, solid all-caps Arial, minimum 24-point font ('F.D.' and '#X of Y' bold, minimum 28-point), attached with permanent epoxy. Panel-interior placards — minimum 7/16" × 3/4", same colors/material, bold all-caps Arial minimum 24-point. 90% · fire department guidance document
• Is a site plan / facility map placard required, and what must it show? Yes — CEC 705.12 requires 'a permanent plaque or directory denoting all electric power sources on or in the premises' (cited in the County's Standard Plan markings sheet), functionally the NEC 705.10 multiple-power-source directory. Separately, LACoFD's Disconnect Schedule (required on any plan set submitted to the Fire Department) is a table — not a site plan — listing every power source, its disconnect designation ('#X of Y'), and the operating device, cross-referenced to the placards. 75% · fire department guidance document
• Where must the labels be placed? At every disconnect/panel/enclosure that must be operated to fully de-energize the structure from a given power source (exterior placards), plus inside panels next to the specific breaker/switch when a panel has multiple relevant switches (panel-interior placards). Standard NEC/CEC labels additionally go at PV junction/combiner boxes, along conduit/raceways carrying PV circuits (every 10 ft, per the marked-up County standard plan), at the AC and DC disconnects themselves, and at the main service panel (power-source directory). 80% · fire department guidance document

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? Within 6 feet of the main service panel, on the same wall plane, not separated by walls/gates/fences/vegetation/architectural features — per LA County Fire Code §509.3, which LACoFD's Sept-2023 guide states governs disconnect/attenuation-means location for electrical hazards (including PV/ESS) at one- and two-family dwellings. I specifically checked Cerritos's own permitting documents for a stricter local electrical-code amendment (as at least one other LA County city has adopted, e.g. requiring the disconnect within 3 feet of the meter) and did not find one. 75% · fire code (via fire department guidance document)
• Must equipment be on a specific approved list? Yes — equipment must be listed and labeled and installed per its listing (CEC 110.3), cited in both the County's submittal/inspection materials and LACoFD's ESS/PV guide; inverters must show a 'utility interactive' listing label, and ESS units are subject to their own listing/rating requirements under LACFC 1207.11. 82% · county submittal bulletin
• Are batteries permitted, and under what conditions? Yes, under LA County Fire Code §1207.11: individual ESS units capped at 20 kWh, aggregate capped at 80 kWh per R-3/R-4 occupancy (in any combination of attached/detached garage, exterior wall, or outdoor-on-the-ground locations); ESS may not be installed inside dwelling units, ADUs, sleeping units, closets, bathrooms, basements, non-garage accessory structures, or vaults; outdoor/exterior-wall units need 5 ft from lot lines/public ways/other buildings/combustibles, 10 ft from vegetation, and 3 ft from doors/windows/operable openings/HVAC inlets; garage-installed units need fire detection (heat alarm, heat detector tied to the house alarm, or sprinkler with flow detection) and impact protection if any part sits below 36 inches AFF in a vehicle-exposed location. 85% · fire department guidance document / fire code excerpt
• Is there a separate ESS permit or inspection? Yes — LACoFD retains ESS plan review and field inspection regardless of the Building & Safety delegation that applies to conventional PV-only systems; LACoFD's Appendix QQ fee schedule carries a distinct 'Energy storage system, Group R-3 and R-4' plan-review fee ($195), and the County's Express Permit guide directs ESS-only scopes to a separate 'Electrical Permit (Complex)' that goes to plan check. 82% · fire department guidance document
• Is there a local rule on service upgrades or busbar sizing? Yes, for the expedited/standard-plan pathway: the PV system must interconnect to a single-phase 120/240V AC service panel with a bus-bar rating of ≤225A, and the sum of the main OCPD plus the inverter/PV backfeed OCPD may not exceed 120% of the bus-bar rating (the standard NEC 705.12(B)(3)(2) rule, explicitly called out in the County's eligibility materials). Systems needing a service/panel upgrade beyond this fall out of the expedited/Express path into standard plan check. 80% · county eligibility checklist
• Is a specific mounting system or attachment spacing required? Yes, quite specific: flush-mount arrays must sit parallel to the roof with a 2"-10" gap under the modules, weigh ≤4 psf (panels + racking) for PV (5 psf for solar thermal), cover no more than half the total roof area, and use anchors meeting County horizontal-spacing tables (by roof slope and rafter spacing) with a wind-uplift lag-screw spec of ≥5/16" diameter and ≥2.5" embedment into the rafter (or a County-approved alternative anchor). 85% · county structural criteria bulletin

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? Phone for the standard, City-processed track — Building & Safety Services Division, (562) 916-1209, Monday-Friday 8am-5pm. Portal (EPIC-LA) for the County Express Solar Roof Mount track. 85% · authority's own department page
• How much notice is required? City (standard track): effectively 1 business day — 'Inspection requests are accepted up until 5 p.m. the day before. Same-day requests are unable to be accommodated.' County (Chapter 68 process, if routed through the County's own office): requests received within business hours are typically scheduled for the next business day, or within a five-day window if the next day isn't available. 85% · authority's own department page
• Are same-day or AM/PM windows offered? No user-selectable AM/PM window — the City publishes a 'Daily Inspection Schedule' giving an estimated arrival-time range per address for that day, described as an estimate 'subject to change at any time,' not a same-day or homeowner-chosen window; same-day requests are explicitly not accommodated. 80% · authority's own department page

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? Delegated — LA County DPW Building & Safety Division performs the building/electrical field inspection (Cerritos is a DPW Building & Safety 'Contract City'); for the County Express Solar product, County staff inspect directly via EPIC-LA scheduling. Where ESS, BIPV, or disconnect placarding are involved, LA County Fire Department performs a separate, additional field inspection that Building & Safety's delegation does not cover. 82% · county department page
• If delegated, to whom? Los Angeles County Department of Public Works, Building & Safety Division (building/electrical, all PV); Los Angeles County Fire Department, Fire Prevention Division (ESS, qualifying BIPV, and disconnect placarding, in all cases, per LACFC §105.3.6 as cited in LACoFD's own guide). 85% · fire department guidance document

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? One combination inspection covering the structural, electrical, and (if applicable) plumbing components together — LA County Building Code §6806.2: 'A combination inspection shall be conducted... One inspection shall be required for the system,' performed only after installation is complete. If ESS/BIPV/placarding scope applies, LACoFD performs a separate, additional field inspection on its own schedule. 82% · county building code chapter
• Is a rough-in or mid-roof inspection required? No — Chapter 68 §6806.2 calls for a single combination final inspection, not a separate rough-in/mid-roof stage. The Building Official may, however, require exposure of specific components (roof-mount fastening, grounding/bonding, module/inverter nameplates) at that single inspection if evidence isn't otherwise sufficient. 80% · county building code chapter

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 — LA County DPW publishes Attachment F, 'Inspection Guide for PV Systems,' and Attachment A summarizes the same checklist items. 85% · published inspection checklist
• What must be on site at inspection? Approved plans and permit/job card on site; the physical labels/signs matching the approved plans and equipment nameplates; and, per the County's checklist, photographs or video showing at least 10% (minimum two) of the total roof-attachment points, since fastening is a common item the inspector may require documented evidence of. 75% · county submittal bulletin
• Does the inspector verify labels and listings? Yes, extensively — the County's published inspection checklist verifies module count/layout/model match to plans, proper grounding/bonding, that all required signs (DC disconnect, AC point of connection, alternate-power-system switch, junction/combiner-box PV circuit signs, raceway PV-circuit signs, power-source directory) are 'properly constructed, installed and displayed,' and that equipment ratings (inverter voltage, DC OCPD ratings, AC OCPD sizing) match both the application and the installed labels. 85% · county submittal bulletin

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 — LA County Chapter 68 frames the outcome as the work being 'approved by the Building Official' following the single combination inspection; no separate Certificate of Occupancy or 'green tag' terminology was used in any Cerritos or County solar-specific document found (this is a retrofit to an existing dwelling, not new construction, so a CO would not typically apply). 65% · county building code chapter
• Who notifies the utility for PTO? Not confirmed from a Cerritos- or SCE-specific document; standard California NEM/Rule 21 practice (which this answer relies on, not a primary source found for this AHJ) has the installer submit proof of the finaled permit to the utility to trigger Permission to Operate. 50% · utility page (dead link, noted)
• Is there a re-inspection fee? $98 confirmed for the fire-related track only — LACoFD's Appendix QQ: 'Additional inspections after initial inspection and one reinspection... $98.00' (miscellaneous field inspection table). No City- or general-Building-and-Safety-specific residential PV re-inspection fee line was found in either Cerritos's Master Fee Schedule or LA County's 2025-2026 Building/Electrical Code Fees PDFs. 65% · fire code fee schedule
• How are corrections issued and cleared? For the plan-review stage: LA County Chapter 68 §6803 requires a written correction notice detailing all deficiencies when an incomplete application is submitted, so the applicant can cure and resubmit. The field-correction process after a failed inspection was not documented in any source found (standard practice would be to contact the inspector/office and request a re-inspection, matching the $98 LACoFD re-inspection fee found under q59, but no Cerritos- or County-specific procedure document was located). 55% · county building code chapter
