City of Poway

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 92% · department page
• What does this authority permit itself, and what does it delegate? Both 85% · municipal code
• Is a permit required for a residential rooftop PV system? Yes 92% · department page
• Is there a separate electrical permit, or is it combined? Combined 80% · municipal code
• Is a HOA or architectural approval required first? No 90% · municipal code
• Is there a historic-district review? No 60% · municipal code index
• Is a wind or windstorm certification required? No 55% · municipal code
• Is a Specific Use Permit or Council approval ever required? Only as an appeal path: if the Building Official finds a specific, adverse impact on public health/safety and denies or conditions an application, that decision may be appealed to the City Council (PMC 15.26.050(E), citing PMC Ch. 2.20). Separately, ground-mount PV requires Planning Dept. (and sometimes Engineering Dept./County Health Dept.) approval, per the City's ground-mount submittal guidance, though this is administrative rather than a legislative SUP/CUP. 75% · municipal code
• Is there a system-size cap on residential generation? 'Small residential rooftop solar PV' (eligible for Ch. 15.26 expedited/ministerial review) is capped at 10 kW AC nameplate (or 30 kW thermal) on a 1- or 2-family dwelling; the City's simplified Solar PV Standard Plan is likewise limited to ≤10kW AC combined inverter output on a ≤225A single-phase service. Larger systems are not banned outright but fall outside the expedited path and must use the Comprehensive Standard Plan / individual engineering. 80% · municipal code

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 85% · application form
• Must the contractor be registered with this authority before applying? No 58% · department page
• Is a homeowner permitted to self-install and self-permit? Yes 88% · 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? Plot plan (existing service/panel location, all solar equipment layout); roof plan (panel/equipment locations, distances to roof edges, pathways); electrical one-line diagram (conductor sizes/insulation, OCPD, grounding, GFCI, disconnects, amperage, voltage); manufacturer spec sheets for panels/inverters/other components; completed Building Permit Application (contractor or owner-builder declaration, workers' comp declaration); for ground mount, foundation/rack construction plans plus Planning Dept and (if on septic) County Health Dept approval. 85% · department handout
• How many copies, and in what format? Electronic submittal only, via the online portal -- 'Effective June 1, 2022, only electronic submittals will be accepted.' 88% · department page
• Is a site plan required, and what must it show? Yes -- a plot plan showing the location of the existing electric service/panel(s) and the location of all solar equipment (panel layout, inverter(s), batteries/generators if any) to be installed under the permit. 85% · department handout
• Is a one-line / three-line diagram required? Yes 90% · standard plan template
• Are string and conductor calculations required? Yes 88% · standard plan template
• Is a structural PE stamp required, and at what threshold? No solar-specific PE stamp threshold is published; the generic citywide rule (B&P Code §5538 as applied by the City's 'Who May Prepare Plans' handout) requires a licensed architect/civil engineer to sign plans for buildings and structures generally, with exceptions letting a registered Building Designer or, for a single-family dwelling with bearing-wall spans ≤25 ft, even an unlicensed private citizen prepare plans. Roof-mount PV using the City's pre-engineered Standard Plan (≤10kW AC, manufacturer-listed racking) does not separately trigger a PE stamp; ground-mount racking requires its own foundation/structural plans which may trigger the general threshold. 55% · department handout
• Is an electrical PE stamp required, and at what threshold? No electrical PE stamp requirement is published for standard residential PV; the City's Standard Plan / Comprehensive Standard Plan process is designed to avoid requiring an electrical engineer's stamp for systems within its scope (≤10kW AC, single inverter/combiner limits, 225A-or-less single-phase service). 45% · standard plan template

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? Tyler Technologies EnerGov Citizen Self Service, branded 'City of Poway Online Services' (cityofpowayca-energovweb.tylerhost.net/apps/selfservice) 88% · portal landing page
• Can the whole application be completed online? Yes 85% · department page
• What does a residential solar permit cost? Approx. $309 for a typical ≤15kW residential rooftop system ($199 base PV permit fee + 25% plan-check fee of $49.75 + $60 permit-issuance fee); systems 15kW+ step up to a $283 base plus $10.84 per additional kW (plus the same 25% plan check and $60 issuance); ground-mount racking adds a separate $649 fee; a residential battery/ESS adds a separate $285 inspection fee. 90% · fee schedule
• How is the fee calculated? Tiered / Per kW 90% · fee schedule
• Is there a separate plan-check fee? Yes 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? Up to 14 calendar days per review cycle for building review (up to 28 calendar days for planning/engineering review), per submittal round; note the City states this in calendar days, not business days. 82% · department page
• How long is an issued permit valid before it expires? 180 days after issuance; must have an inspection at least every 6 months to stay active, or additional fees apply to reactivate. 85% · department FAQ
• Which utility handles interconnection here? SDG&E (San Diego Gas & Electric) 78% · department handout
• Where does the utility sit in the sequence? Parallel / No dependency for a standard system; Before permit only if the application includes an electrical meter/service upgrade. 82% · municipal code

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 92% · municipal code
• Which building code edition is in force? 2025 California Building Code, Part 2, Title 24 (based on the 2024 International Building Code) 92% · municipal code
• Which fire code edition is in force? 2025 California Fire Code, Part 9, Title 24 90% · municipal code
• Are there local amendments to any of the above? Yes 85% · municipal code
• What is the installation judged against? The 2025 CBC/CRC, 2025 CEC (2023 NEC base), and 2025 CFC as codified in PMC Title 15, plus the City's own Solar Compliance List and Solar PV Standard Plan handouts -- though those handouts still cite 2022 CEC/2022 CRC article numbers, one code cycle behind the City's current 2025 adoption (a discrepancy worth flagging, not resolving). 75% · department handout

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? Per the current (2024-revised) Solar Compliance List, citing 2022 CRC R324.6 et seq.: two 36-inch pathways from eave to ridge (one on the street/driveway side), 18-inch clear ridge setback where the PV array covers ≤33% of the roof plan area (36 inches if >33%; relaxed to 18"/36" at 66% thresholds where an NFPA 13D sprinkler system is installed), and a 36-inch pathway to any emergency escape/rescue opening. NOTE: a separate City handout ('CRC Solar Voltaic System Access and Pathway Requirements') still uses the SUPERSEDED pre-2019 section numbering (R331.4 series) -- a live internal contradiction; the newer, more detailed Solar Compliance List is preferred. No local Fire Code amendment on this topic was found after reading the full codified PMC 15.24.015-140 amendment list. 65% · department handout

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 required per NEC 690.12 (current post-2017 array-boundary/controller-based scheme, not the pre-2019 scheme). The City's Solar Compliance List cites '2022 California Electrical Code Article 690.12' for the initiation device and shutdown requirements; the City has since adopted the 2025 CEC (based on 2023 NEC) by ordinance, whose 690.12 substance is materially the same rapid-shutdown scheme. 68% · department handout

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? (a) A rapid-shutdown label at each service equipment location with City-quoted wording (see Q39); (b) per an older (2014-revision) handout still linked from the same solar page: a main-service placard ('THIS ELECTRIC SERVICE IS ALSO SERVED BY A PHOTOVOLTAIC POWER SYSTEM'), a PV-disconnect label ('PHOTOVOLTAIC DISCONNECT MEANS'), and a shock-hazard warning label where disconnect terminals may be energized in the open position; (c) point-of-interconnection labels per NEC 705.10/690.56; (d) DC circuit/equipment markings per 690.13(B), 690.31, 690.53; (e) ESS notification/marking labels per NEC 706.15(C). 65% · department handout
• Does the authority specify placard wording of its own? Yes 80% · department handout
• Does it specify letter height, colour or material? No 65% · department handout
• Is a site plan / facility map placard required, and what must it show? Yes -- a point-of-interconnection/power-source identification label per NEC 705.10 and 690.56 is required at the service equipment; separately, the roof/site plan itself (showing panel, pathway, and equipment layout) must be provided to the building inspector at every field inspection. 75% · department handout
• Where must the labels be placed? Adjacent to the main electric service (service disconnect placard); at the PV system disconnecting means; at DC circuit raceways/junction boxes; at the PV/DC equipment disconnect; at the point of interconnection/busbar; and, where an ESS is installed, at the ESS location/notification point. 80% · department handout

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 85% · department handout
• Are batteries permitted, and under what conditions? Yes, with conditions -- ESS must be UL 9540 listed and labeled (2022 CRC R328.2, as cited by the City); where smoke alarms cannot be installed inside the ESS space due to the ESS listing, an interconnected heat detector is required so all smoke alarms activate together (2022 CRC R328.7); a floor plan showing the ESS location must be provided at inspection. 80% · department handout
• Is there a separate ESS permit or inspection? Ambiguous / partially yes -- the Building Division bills a distinct 'Residential Battery Inspection' fee ($285) alongside (not instead of) the Solar PV permit fee, suggesting a separate inspection step rather than a wholly separate permit. Separately, the Fire Department's Master Fee Schedule lists 'Energy Storage Systems' as its own line under both annual CFC operational permits and fire construction/improvement permits -- but this appears in a generic alphabetized CFC Chapter 1 permit-type list (alongside items like 'Lithium Batteries,' 'Fuel Cell Power Systems') with no stated capacity floor, and it is not clear from the fee schedule alone whether this Fire line applies to a typical single-family residential home battery or is scoped to commercial/multi-family occupancies. 55% · fee schedule
• Is a ground mount treated as a structure? Yes 80% · department handout
• Is there a local rule on service upgrades or busbar sizing? The City's simplified Solar PV Standard Plan may only be used for systems interconnecting to a single-phase 120/240V service with a busbar/panel rating of 225A or less; larger or more complex services require the Comprehensive Standard Plan. Separately, any application including an electrical meter/service upgrade requires SDG&E approval before the City will issue the permit (PMC 15.26.050(A)). 80% · standard plan template
• Is a specific mounting system or attachment spacing required? No prescriptive city spacing table; the racking/mounting system must be manufacturer-rated for local wind uplift and evenly distribute loads at the proposed spacing, and must be listed under UL 1703/61730/2703 or UL 2703 for grounding/bonding -- verified by the inspector against the manufacturer's installation instructions rather than a City standard detail. 70% · department handout

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 or Portal 80% · department page
• How much notice is required? Effectively next business day -- requests received before 4 p.m. are scheduled for the next business day unless a later date is requested; no minimum multi-day advance-notice requirement stated. 78% · 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 85% · department page
• If delegated, to whom? EsGil Corporation 88% · department page

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? Roof mount: one consolidated final inspection after completion of equipment, signage and conductors (system disconnect left OFF until complete). Ground mount: underground electric → foundation → framing for rack system → service upgrade (if applicable) → rough electric (after concealed wiring) → final. 78% · department handout
• Is a rough-in or mid-roof inspection required? No for roof-mount small residential (one consolidated final only, per PMC 15.26.050(F)); Yes for ground-mount (separate foundation, framing/rack, and rough-electric inspections precede the final). 70% · municipal code

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 80% · department handout
• What must be on site at inspection? Complete plan set with one-line schematic (equipment/conduit/conductor schedule, string calcs, MCI/optimizer/microinverter/inverter/combiner/load-center specs); roof plan showing module and pathway locations; and manufacturer datasheets for modules, optimizers, micro-inverters, MCI, inverter, combiner box, load center, surge protection device, roof sealant, racking system, rapid-shutdown system, HCS, all disconnecting devices, and (if present) ESS devices plus an ESS floor plan. 90% · department handout
• Does the inspector verify labels and listings? Yes 82% · department handout

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 62% · department handout
• Is there a re-inspection fee? No flat fee; billed at EsGil Corporation's 'current preferred hourly rate' (one-hour minimum) for additional inspections/re-inspections/revised-plan review beyond the included cycles. 78% · fee schedule
• How are corrections issued and cleared? A written or emailed correction notice detailing all deficiencies and any additional information/documentation needed is sent to the applicant, who resubmits electronically for another review cycle (up to 14 calendar days for building / 28 for planning-engineering per cycle). 78% · municipal code
