City of San Gabriel

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 incorporated San Gabriel addresses 95% · authority's own page
• What does this authority permit itself, and what does it delegate? Both 85% · department page
• Is a permit required for a residential rooftop PV system? Yes 95% · published checklist
• Is there a separate electrical permit, or is it combined? Combined 70% · fee schedule
• Is a HOA or architectural approval required first? No HOA approval requirement stated by the City; a City Design Review (not HOA) is conditionally required if the system is street-facing 75% · published checklist
• Is there a historic-district review? Yes 95% · published checklist
• Is a wind or windstorm certification required? No formal windstorm/TDI-style certification (not applicable in CA); wind-uplift structural calculations under ASCE 7-10 are required instead 60% · published checklist
• Is there a system-size cap on residential generation? No hard system-size cap identified; <15kW is a fee/process tier boundary (separating the 'Residential Solar Permit' fee category from the 'Other e.g. Commercial, Multi-Family' category), not a stated ceiling on residential system size 55% · fee schedule

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 65% · authority's own page
• Must the contractor be registered with this authority before applying? Yes 90% · authority's own page
• Is a homeowner permitted to self-install and self-permit? Yes, on the standard (non-SolarAPP+) track only 65% · department page

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 Residential Solar Power Systems Permit Issuance Checklist (<10kW systems): (3) sets of plans minimum 11x17, manufacturer specification sheets, installation instructions, framing layout, structural calculations (if applicable); an electrical single-line diagram showing all PV devices and total kW rating; circuit-sizing/current calculations per then-CEC Art. 690.8 signed by a CA-licensed electrical engineer or C-46/C-10 contractor; wet-stamped structural wind-uplift calculations (ASCE 7-10) from a licensed civil/structural engineer; UL 1703 fire-classification documentation; plans signed by the installing C-46/C-10 contractor with license number on every sheet. 90% · published checklist
• How many copies, and in what format? Minimum 3 sets of plans, 11"x17" or larger, for first-time counter submittal; for digital resubmittals, plans are emailed as clouded/marked-up PDFs to commdevinfo@sgch.org 80% · department handout
• Is a site plan required, and what must it show? Yes -- address, APN, zone, lot size, technology type (BIPV/roof-mount/ground-mount), panel count/area/kW, whether panels sit on a permitted structure, roof height above roof-plane, panel directional orientation, and visibility from public streets 90% · published checklist
• Is a one-line / three-line diagram required? Yes 90% · published checklist
• Are string and conductor calculations required? Yes 85% · published checklist
• Is a structural PE stamp required, and at what threshold? Yes, for all systems the checklist covers (which the form itself limits to installations under 10 kW): wet-stamped, signed structural calculations for wind uplift based on ASCE 7-10, from a state-licensed civil or structural engineer, with all structural elements identified on the existing roof framing plans 80% · published checklist
• Is an electrical PE stamp required, and at what threshold? Not mandatory if a CA-licensed C-46 or C-10 contractor signs the electrical plans; an electrical PE stamp is only implicated if the applicant instead routes through a state-licensed electrical engineer 65% · published 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.

• What does a residential solar permit cost? $450 total (residential, <15kW), on either track 90% · fee schedule
• How is the fee calculated? Tiered / Flat 85% · fee schedule
• Is there a separate plan-check fee? Yes on the standard track ($185 line item); No separate plan-check fee on the Automated/SolarAPP+ track 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.

• Which utility handles interconnection here? Southern California Edison (SCE); no CCA 80% · city council staff report / agreement

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? Other -- code-cycle in transition, exact adopting ordinance text not retrievable 50% · department handout (dated), corroborated by department page
• Which building code edition is in force? 2022 CBC per the most recent dated handout found; City has announced transition to the 2025 CBC cycle effective 1 Jan 2026 with local structural amendments, but the adopting ordinance text could not be retrieved 50% · department page (undated announcement)
• Are there local amendments to any of the above? Yes -- at minimum, local structural amendments for the 2025 code cycle 70% · department page
• What is the installation judged against? Per the City's checklist: 2019 CEC Art. 690 (PV systems) and Art. 705 (interconnected power production sources); UL 1703 fire-classification per CBC Table 1505.1; CRC 2019 Sec. R907 fire setbacks; and general conformance to the 'California Solar Permitting Guidebook' 75% · published checklist

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? Checklist requires compliance with CRC 2019 Sec. R907 fire setbacks for roof-mounted PV, but does not restate the numeric pathway/setback table itself; no separately-published local pathway-and-setback amendment was located 55% · published 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? Yes by state code (CEC Art. 690.12 rapid-shutdown applies statewide regardless of local citation), but the City's own checklist never cites Sec. 690.12 by number 55% · published checklist (absence proven by full-text grep)

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.

Nothing recorded for City of San Gabriel on this step yet — 6 questions checked and found unpublished. The guidance above is general.

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% · published checklist
• Is there a local rule on service upgrades or busbar sizing? A City handout ('Electrical Panel Upgrade Requirements') requires an electrical permit for any main-panel replacement/upgrade, and reprints standard NEC service-entrance, busbar-grounding and workmanship provisions -- but it contains no PV-specific busbar/backfeed sizing rule (no 705.12 or '120% rule' language) 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? Portal (online form), with a direct phone/text line to the assigned inspector 80% · department page
• How much notice is required? Effectively next business day: cut-off is 4:00 PM Monday-Thursday and 3:00 PM Friday for the next day's schedule 75% · department page
• Are same-day or AM/PM windows offered? No stated AM/PM window selection; the daily schedule (not a time slot) posts at 7:30 AM the day of inspection and applicants check it to see where they fall 60% · 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 85% · department page
• If delegated, to whom? Not delegated -- performed in-house by the City's own Building Inspector 80% · 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? A single final inspection appears to be the norm for rooftop PV (no staged sequence is published for solar specifically) 45% · inference from department page silence

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 90% · published checklist
• What must be on site at inspection? Approved plans and the inspection card 85% · department page
• Does the inspector verify labels and listings? Likely yes, though not stated as an explicit inspection-day checklist item 55% · inference from submittal 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 (closed/approved inspection card on the permit); a separate Certificate of Occupancy is a distinct, separately-fee'd product not typically triggered by a PV retrofit on an existing residence 45% · inference from fee schedule + department page
• Is there a re-inspection fee? Cost-recovery ('Staff Full Burden Rate plus outside costs'), not a flat dollar figure 65% · fee schedule
• How are corrections issued and cleared? For plan-check corrections: revisions are emailed to commdevinfo@sgch.org with changes clouded on the plans and each comment individually addressed on both plans and a comment sheet, including the last City review set 70% · department handout
