City of Coronado

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 95% · department page
• What does this authority permit itself, and what does it delegate? Both 90% · permit application form
• Is a permit required for a residential rooftop PV system? Yes 96% · fee schedule
• Is there a separate electrical permit, or is it combined? Combined 82% · permit application form + issued-permit log
• Is a HOA or architectural approval required first? No dedicated HOA/architectural approval trigger found for a standard rooftop PV retrofit 60% · department page (scope-based inference)
• Is there a historic-district review? Yes, for designated Historic Resources - a Historic Resource Alteration Permit (HAP) is required by CMC Ch. 84.20 for 'any exterior alteration' of a Designated Historic Resource, decided at a noticed public hearing before the Historic Resource Commission; no solar-specific exemption was found anywhere in the City's own Historic Preservation Program Guidebook 85% · department guidebook (control-proven)
• Is a wind or windstorm certification required? No dedicated windstorm-certification requirement found; the Eligibility Checklist's Structural Requirements do not include a Wind-Exposure screening item of the kind neighboring Imperial Beach's worksheet uses 60% · department checklist (partial absence)
• Is a Specific Use Permit or Council approval ever required? Not routinely - the standard Eligibility Checklist/OTC pathway does not mention a CUP; the only documented Council-level path found is specific to Historic Resources: if a Historic Resource Alteration Permit application 'includes requests for relief from zoning requirements,' the Historic Resource Commission makes a recommendation and the City Council holds its own noticed hearing (fee: 'HAP with Code Exceptions* (to City Council)' $146) 55% · fee schedule + guidebook
• Is there a system-size cap on residential generation? 10 kW AC nameplate gates the over-the-counter/expedited pathway for roof-mounted PV on one- and two-family dwellings; larger systems (and any system with battery storage) are not barred but are routed to standard, non-expedited plan review 90% · department checklist

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 - licensed contractor (Contractor's License field) or owner-builder (must complete an Owner-Builder Verification Form) 85% · permit application form
• Must the contractor be registered with this authority before applying? Yes - a City of Coronado Business Certificate is required of any contractor doing business in the city 70% · department page + permit application form
• Is a homeowner permitted to self-install and self-permit? Yes 88% · permit application form

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? Completed Building Permit Application; the Eligibility Checklist for Expedited Solar Photovoltaic (or, for non-eligible systems, standard plans); a complete plan set showing main service/utility disconnect location, module/string/inverter counts, one-line diagram, grounding/bonding and conductor/conduit sizing, battery locations if applicable, equipment cut sheets, CEC 690/705 labeling, and a site diagram plus a roof plan showing roof layout, panels, access point, code-compliant access pathways, fire classification and label locations 92% · department page
• How many copies, and in what format? Not stated specifically for solar; the City's general Plan Review Process handout (non-OTC categories) requires three (3) sets of construction drawings plus two (2) sets of supporting documentation, min/max plan sheet size 24 x 36 inches 60% · department handout
• Is a site plan required, and what must it show? Yes - a site diagram showing the arrangement of panels on the roof or ground, north arrow, lot dimensions and distance from property lines to adjacent buildings/structures (existing and proposed), plus a roof plan showing layout, access point, access pathways, fire classification and label locations 92% · department page
• Is a one-line / three-line diagram required? Yes 90% · department page
• Are string and conductor calculations required? Yes 82% · department page + eligibility checklist
• Is a structural PE stamp required, and at what threshold? Conditional - the Eligibility Checklist's Structural Requirements section requires 'Complete structural criteria and supporting documentation... (if required)' and screens for a sound, single (non-overlay) roof with no overhang; no dedicated public structural-criteria worksheet or PE-stamp threshold document (of the kind other San Diego County cities publish) was found on the City's site 60% · department checklist (partial absence)

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? CentralSquare TRAKiT (city's Building/Permitting system of record), plus SolarAPP+ for eligible contractor submittals 85% · department page (SB 272 catalog)
• Can the whole application be completed online? Partially/conflicting - SolarAPP+ allows a fully-online, instant path for eligible contractor submittals, but the Solar Photovoltaic page's own general instructions still state that 'Permit applications must be submitted to the City of Coronado Building Division in person at 1825 Strand Way' 65% · department page (internal conflict)
• What does a residential solar permit cost? $0 base fee, plus actual plan-check costs from an outside contractor, capped at $500 for a residential roof-mounted system 78% · fee schedule (conflict with department incentive page)
• How is the fee calculated? Flat ($0) with an actual-cost, outside-contractor plan-check pass-through capped at $500 for residential 75% · fee schedule
• Is there a separate plan-check fee? Effectively yes for non-eligible systems - the fee schedule's solar line separately passes through 'actual plan check costs from outside contractor' up to $500, and the City's own Plan Review Process handout confirms an 'External Plan Review' category is performed by 'the City of Coronado's Plan Review Consultant' and 'Third Party Plan Reviewers'; for eligibility-checklist-compliant systems reviewed over-the-counter, the Green Energy Incentive Program page advertises the permit as free 68% · department handout + fee schedule (conflict)

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? Over-the-counter (~15-30 minutes) for Eligibility-Checklist-compliant systems; otherwise routed to 'Submitted - Internal' or 'Submitted - External' review, both stated at roughly 10-12 business days for the initial round of comments 78% · department handout
• How long is an issued permit valid before it expires? Not stated specifically for an issued solar permit; the City's Plan Review Process handout (quoting adopted CBC Sec. 105.3.2) states a PLAN CHECK APPLICATION is deemed abandoned 180 days after filing unless pursued in good faith or a permit is issued, with one 90-day extension available on written request 55% · department handout (partial)
• Which utility handles interconnection here? SDG&E (San Diego Gas & Electric) 88% · department page + city infrastructure document
• Where does the utility sit in the sequence? After permit 68% · utility tariff (prior-run extraction)

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? Uncertain/lagging - the City's own Plan Review Process handout, last revised March 2025, cites '2022 California Building Code' (i.e. the 2022 CEC, based on the 2020 NEC) as its authority; California's 2025 Title 24 cycle (2025 CEC, based on the 2023 NEC) took effect statewide 1 Jan 2026 by default, but no City document confirming local re-adoption or continued citation of the 2022 cycle after that date could be retrieved this session 50% · department handout (lag flagged)
• Which building code edition is in force? 2022 California Building Code cited in the City's most recently revised (March 2025) Plan Review Process handout; current statewide default since 1 Jan 2026 is the 2025 CBC, not independently confirmed as locally re-adopted this session 50% · department handout (lag flagged, code portal blocked)
• Which fire code edition is in force? Conflicting/stale evidence - a 2021 Wayback capture of the codified fire chapter (CMC 70.90.010) showed the 2019 California Fire Code adopted via Ord. 2096 (2019); a separate City FAQ page states the City regulates fireworks 'in accordance with the 2016 California Fire Code as amended and adopted by the City of Coronado.' Neither reflects a confirmed current adoption; the live code portal was unreachable this session 45% · archived municipal code + FAQ (conflicting, stale)
• Are there local amendments to any of the above? Yes, at least administratively - the 2021-captured Fire Code chapter amends CFC Sec. 202's definition of 'fireworks,' and the Plan Review Process handout quotes locally-adopted CBC administrative amendments (Sec. 105.3.2 application abandonment, extension provisions); whether any PV-specific technical amendment exists could not be confirmed because the code portal was Cloudflare-blocked 55% · department handout + archived code (partial)
• What is the installation judged against? The adopted CBC/CRC/CEC/CFC (edition uncertain this session, see Q29-31) as implemented through the City's own Eligibility Checklist for Expedited Solar Photovoltaic and its solar submittal requirements; no codified, numbered 'small residential rooftop solar' municipal code chapter (of the kind many other CA cities carry, e.g. an XX.YY 'Solar Energy Systems' chapter) was located, though the code portal being blocked means one may exist unseen 62% · department checklist (code portal blocked)

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? Clear access pathways dimensioned per CRC Sections R324.6.1-R324.6.2.1 80% · department checklist

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? Rapid shutdown per CEC/NEC Sec. 690.12 is presumed required as a matter of the adopted electrical code, but the City's own solar documents never cite it by number -- the Eligibility Checklist (dated November 2020) cites only CEC Sec. 690.56 for markings/labels and never mentions '690.12' or the phrase 'rapid shutdown' anywhere in the City's solar document corpus checked 68% · department checklist (control-proven non-citation)

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? General labeling/markings 'as required by CEC, Sections 690 and 705' per the Solar page's submittal list, and markings/labels/placards 'per CEC sec 690.56' per the Eligibility Checklist's Fire Safety Requirements; no city-specific list of named placards (comparable to Imperial Beach's PV Minimum Construction Specifications sheet) was found 60% · department page (partial absence)
• Does the authority specify placard wording of its own? No 65% · department page (absence)
• Does it specify letter height, colour or material? No City-specific letter height, colour or material spec was found 62% · department page (absence)
• Is a site plan / facility map placard required, and what must it show? A site diagram/roof plan showing panel arrangement, north arrow, lot dimensions, property-line setbacks, roof access point, access pathways, fire classification and label locations is required in the submittal package; no separate field-mounted facility-map placard requirement (beyond NEC 705.10) was found 65% · department page
• Does the UTILITY specify placards beyond the AHJ's? Yes - SDG&E Rule 21 Sec. H.1.d 'Visible Disconnect Required' (open/closed markings, lockable, reachable 24/7, shown on the single-line diagram) 62% · utility tariff (prior-run extraction)
• Where must the labels be placed? Not specified beyond general CEC 690/705 labeling requirements; the City publishes no location-by-location placement diagram of its own 55% · department page (absence)

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.

• Must equipment be on a specific approved list? Yes, implicitly - equipment cut sheets for inverters, modules, AC/DC disconnects, combiners and wind generators are required in the plan set, and equipment must be labeled per CEC Sections 690/705, which in practice requires listed equipment 60% · department page (inference)
• Are batteries permitted, and under what conditions? Yes, permitted, but a system 'without storage batteries' is required to qualify for the expedited/over-the-counter pathway; a system WITH batteries is routed to standard (non-expedited) review. The Green Energy Incentive Program's free-permit waiver explicitly extends to 'Home Battery Systems.' 85% · department checklist + incentive page
• Is there a separate ESS permit or inspection? No separate ESS permit found - battery storage appears to be bundled into the same electrical/PV permit as the solar system 65% · issued-permits log (inference)
• Is a ground mount treated as a structure? Very likely yes, though not independently confirmed against the current code - the (2013-vintage, Wayback-archived) Zoning Definitions chapter defines 'Structure' broadly as 'anything over two feet in height above grade constructed or erected, which requires location on the ground or attached to something having a location on the ground,' with no photovoltaic carve-out (fences/walls under 8 ft, ornamental post lights, and certain underground-utility aboveground facilities are the only listed exceptions) 60% · archived municipal code (stale, flagged)
• Is there a local rule on service upgrades or busbar sizing? 225A is used as an ELIGIBILITY CEILING for the expedited/OTC pathway ('interconnected to a single-phase AC service panel of nominal 120/220 Vac with a bus bar rating of 225 amps or less'), not stated as a general local code minimum; no separate codified busbar-sizing ordinance (Palm Springs-style) was found or ruled out 70% · department checklist
• Is a specific mounting system or attachment spacing required? Only general criteria in the Eligibility Checklist: modules must not overhang any roof edge, the roof must be a single roof without a reroof overlay and appear structurally sound, and a roof plan with anchor layout must be attached; no dedicated anchor-spacing table or fastener specification (of the kind Imperial Beach publishes) was found on the City's site 60% · department checklist (partial absence)

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 92% · department page
• How much notice is required? Effectively next business day - inspections called in before 4pm on a regular business day are scheduled for the next business day; requests left on weekends or City holidays are scheduled for the second business day 92% · department page
• Are same-day or AM/PM windows offered? Yes - AM (8 to noon) or PM (1 to 4) 88% · 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? Yes 92% · department checklist
• If delegated, to whom? N/A - self-performed by the City's own Building Department 90% · department checklist

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? A single consolidated final inspection after the system is fully installed 88% · department page + checklist
• Is a rough-in or mid-roof inspection required? No 88% · department checklist

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 95% · department checklist
• What must be on site at inspection? A safe/secure ladder already in place; junction box(es) accessible and open; the installed panel layout matching approved plans exactly (any deviation is an immediate failure); inverter(s)/junction boxes open for inspection; attic access ready if conduit runs through the attic; all ground rods/UFERs accessible with water/gas bonding verifiable; the main service panel dead front labeled, removed and set aside with placards matching approved plans; and the approved plan set plus the original permit inspection record card on site 90% · department checklist
• Does the inspector verify labels and listings? Yes 85% · department checklist

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 (final approval of the solar system) 78% · department page
• Who notifies the utility for PTO? Installer (applicant), inferred 55% · utility tariff (inference)
• Is there a re-inspection fee? No dedicated PV re-inspection fee line; the general hourly rate would apply -- Electrical Inspection (per hour, 1/2 hour minimum) is $172 current / $178 proposed for FY2026-27 55% · fee schedule (inference)
• How are corrections issued and cleared? A field deviation from approved plans results in immediate failure of the inspection; if three or more items on the Single Inspection PV Checklist are not ready at the time of inspection, a re-inspection fee is assessed and must be paid before another inspection can be requested. For plan-check-stage corrections, comments are forwarded to the applicant for incorporation into revised drawings, which must be resubmitted until all reviewing authorities are satisfied 78% · department checklist + handout
