City of San Pablo

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% · city ordinance / department page
• What does this authority permit itself, and what does it delegate? Building 90% · codified ordinance
• Is a permit required for a residential rooftop PV system? Yes 95% · codified ordinance
• Is there a separate electrical permit, or is it combined? Combined 75% · fee schedule
• Is a HOA or architectural approval required first? No — expressly barred 92% · codified ordinance
• Is there a historic-district review? No 70% · municipal code full-text search
• Is a wind or windstorm certification required? No 65% · municipal code full-text search
• Is a Specific Use Permit or Council approval ever required? Yes, conditionally 90% · codified ordinance
• Is there a system-size cap on residential generation? 10 kW AC nameplate (or 30 kW thermal) for the codified 'small residential rooftop solar' expedited definition, restricted to single- or duplex-family dwellings, and the array must not exceed the maximum legal building height; the city's own Expedited PV eligibility form repeats the 10kW AC ceiling as a hard gate for its over-the-counter path (systems above 10kW, or non-single-family, or with battery storage, are routed to standard/full plan check rather than being barred outright). 88% · codified ordinance

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? Licensed electrician 55% · department form
• Must the contractor be registered with this authority before applying? No 55% · department page
• Is a homeowner permitted to self-install and self-permit? Yes 70% · checklist

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? Site plan; structural plan (foundation/cross-sections/framing if ground-mounted); electrical (one-line) plan; structural calcs if applicable; manufacturer specs for modules/inverter/combiner/disconnects/mounting; colored photos of existing main and sub-panels; building permit application; Owner/Builder form if applicable; Con Fire Solar-Photovoltaic Notification Form; copy of the executed installer contract. 92% · published checklist
• How many copies, and in what format? 3 sets of drawings (4 sets if system >10kW AC), 2 sets of calculations/specifications; electronic plans also required per the general permit process; suggested minimum drawing sheet size 18"x24". 90% · published checklist
• Is a site plan required, and what must it show? Yes — site plan must show location of modules (each string identified), electrical service, combiner boxes, inverter, AC/DC disconnects, conduit, junction boxes, battery banks, and roof-clearance compliance with State Fire Marshal / Con Fire PV Installation Guidelines. 92% · published checklist
• Is a one-line / three-line diagram required? Yes 90% · published checklist
• Are string and conductor calculations required? Conditional 75% · published checklist
• Is a structural PE stamp required, and at what threshold? Required only if the Structural Criteria checklist fails any item: 'Attach project-specific drawings and calculations stamped and signed by a California-licensed Civil or Structural Engineer' — no PE stamp required if all checklist items (flush-mount, weight, roof condition, anchor spacing/fastener criteria) pass. 88% · 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.

• Which permit portal does this authority use? No dedicated e-permitting portal (no Accela/EnerGov/CityView found); the city routes PV and other submittals through a Dropbox file-request link, with permit issuance, fee payment and inspection scheduling handled by phone (510-215-3030). 88% · department page
• Can the whole application be completed online? No 85% · department page
• What does a residential solar permit cost? $450 flat (residential PV, up to 15kW, includes plan check + inspection) plus $15/kW for each kW above 15kW; residential PV battery storage systems (200A or less) are a separate $450 flat line. 95% · fee schedule
• How is the fee calculated? Tiered 90% · fee schedule
• Is there a separate plan-check fee? No 80% · 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? 10 working days (residential, all review cycles) per the published checklist; separately, SPMC 15.63.060(A) requires the Building Division to approve/deny complete expedited PV applications same-day (over-the-counter) or within 1–3 days where OTC is not feasible. 85% · published checklist
• How long is an issued permit valid before it expires? 180 days 65% · codified ordinance amendment
• Which utility handles interconnection here? PG&E 85% · city department page
• Where does the utility sit in the sequence? Before permit is not asserted; utility interconnection with PG&E runs in parallel with/after the city permit and PTO is gated on the AHJ's final-inspection clearance per PG&E's own Rule 21 tariff (§D.13.b) — this is a utility-level fact from PG&E's tariff, not confirmed against a San Pablo-specific document this run. 55% · utility tariff

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 NEC (via the 2025 California Electrical Code, Title 24 Part 3) 80% · department announcement + statewide adopting document
• Which building code edition is in force? 2025 California Building Code (Title 24), effective 19 Feb 2026 per the city's own announcement; the codified SPMC 15.04.010 (current only through Ord. 2024-001, March 2024) still recites the 2022 CBC — the codified chapter has not caught up to the city's stated current practice. 82% · department announcement
• Which fire code edition is in force? 2025 California Fire Code, per Contra Costa County FPD Ordinance No. 2025-14 (adopted 18 Nov 2025, operative 1 Jan 2026); SPMC 15.04.010(A)(9), codified only through March 2024, still recites the 2022 CFC under the superseded County Ord. 2022-34 — Con Fire's own Ord. 2025-14 §722-2.006 explicitly says references to the 2022 code 'shall be construed to apply' to the 2025 code, and San Pablo is named by name in the same ordinance's more-restrictive-requirements clause (§722-2.010). 90% · adopting ordinance
• Are there local amendments to any of the above? Yes 90% · codified ordinance
• What is the installation judged against? The 2025 California Electrical Code (Title 24 Part 3, based on the 2023 NEC) as locally amended, per SPMC 15.63.040(C) ("all applicable safety and performance standards established by all parts of Title 24... including the California Electrical Code") plus UL/IEEE listing and CPUC safety/reliability rules. 85% · codified 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? Con Fire's own Solar Application (PV) form specifies: for Group R-3 (1-and-2-family) buildings, two 36-inch pathways on separate roof planes from lowest edge to highest ridge (at least one on the street/driveway side) per CFC 1205.2.1.1; for other buildings, 6 ft (or 4 ft where either axis ≤250 ft) perimeter clearance per CFC 1205.3.1; interior pathways at 150 ft intervals, 4 ft clear to skylights/hatches, per CFC 1205.3.2; smoke-ventilation pathway rules per CFC 1205.3.3. The city's PV checklist separately references 'roof clearances compliance to the State Fire Marshall and Contra Costa Fire Protection District Photovoltaic Installation Guidelines.' The Expedited PV form (2021, stale) separately states a simplified '3 feet below ridge, 3 feet from gable ends' rule. 90% · fire district plan-review form

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? Required for buildings with rapid-shutdown PV systems, per the current NEC edition adopted (2023 NEC via the 2025 CEC as of 19 Feb 2026 in San Pablo). Con Fire's own Solar Application (PV) form separately mandates a specific permanent label (see Q38-40) tied to CFC 1205.5.1, which corresponds to NEC 690.12 rapid-shutdown labeling. 75% · fire district plan-review form

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? DC-circuit/conduit warning placards ('WARNING: PHOTOVOLTAIC POWER SOURCE') at every DC wiring method/enclosure per CEC 690.31(D)(1)-(2); a rapid-shutdown placard at the service equipment; the Con Fire notification/inspection process (Eng.026) triggers no separate placard of its own. 90% · fire district plan-review form
• Does the authority specify placard wording of its own? Yes 92% · fire district plan-review form
• Does it specify letter height, colour or material? DC marking: minimum 3/8" letters, white on red, weather-resistant reflective material. Rapid-shutdown label: first two lines uppercase, minimum 3/8" height, black lettering on yellow background, permanent label. 92% · fire district plan-review form
• Is a site plan / facility map placard required, and what must it show? Yes — a roof-layout diagram is required showing all panels/modules, clear access pathways, and the approximate locations of electrical disconnecting means and roof access points. 88% · department form
• Where must the labels be placed? DC markings at: exposed raceways/cable trays, covers/enclosures of pull and junction boxes, unused conduit-body openings, every enclosure/wall/partition/ceiling/floor crossing, every 10 feet, and at all DC combiner/junction boxes; rapid-shutdown label at the service equipment. 90% · fire district plan-review form

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? Not confirmed from a San Pablo-specific document this run; PG&E's general DG interconnection practice places the AC disconnecting means readily accessible near the meter with visible open/closed position markings (per PG&E's Rule 21 tariff), but this was not independently re-verified against the full tariff or a Greenbook excerpt in this run. 45% · utility tariff (inference)
• Must equipment be on a specific approved list? Yes, in substance 75% · codified ordinance
• Are batteries permitted, and under what conditions? Permitted, but excluded from the city's expedited/over-the-counter PV path — the Expedited PV eligibility form requires 'no battery storage' as a condition of OTC eligibility (item 4), meaning battery-equipped systems route to standard plan check. At the county fire level, Con Fire treats 'Battery Systems/Energy Storage' as its own plan-review category with a $944 minimum fee plus a $516 minimum UL 9540A review fee. 88% · fee schedule
• Is there a separate ESS permit or inspection? Yes 85% · fee schedule
• Is a specific mounting system or attachment spacing required? Flush-mount rack/anchor spacing governed by the city's own Structural Criteria table (anchor horizontal spacing by roof slope/rafter spacing/framing type, e.g. 16"/24"/32" o.c.), with engineer stamp required only if any pass/fail item fails; ground-mounted systems separately require a foundation/pier-and-grade-beam structural plan per the PV checklist. 88% · published checklist

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 88% · department page
• How much notice is required? 2 business days (fire final, per Con Fire); no minimum notice period is separately published for the city building final. 75% · fire district plan-review form
• Are same-day or AM/PM windows offered? Building inspections run Monday–Thursday (no Friday inspections, matching the city's 4-day work week); Con Fire final inspections run Monday–Thursday and additionally require a confirmation call between 8:00–8:30am the morning of, or the inspection is cancelled — effectively an AM-confirmed, not a fixed AM/PM window. 80% · 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% · codified ordinance
• If delegated, to whom? Not delegated for the building final (performed in-house by the city's own Building Division/Chief Building Official). The fire life-safety portion is held independently by Contra Costa County Fire Protection District (Con Fire), which performs its own separate final PV inspection. 82% · department staff directory (in-house negative) + fire district form

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? Building: a single consolidated final inspection for expedited-eligible small residential rooftop PV systems (SPMC 15.63.060(G)); if it fails, a subsequent re-inspection is authorized. Fire: a separate Con Fire final inspection, scheduled independently, following the Con Fire plan-review approval and the Solar-Photovoltaic Notification Form (Eng.026). 82% · codified ordinance
• Is a rough-in or mid-roof inspection required? No, for the expedited/eligible path 78% · codified ordinance

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 85% · published checklist
• What must be on site at inspection? Approved/stamped plans, the Expedited PV eligibility checklist (or standard-path equivalent), the structural criteria worksheet (if used), the executed installer contract, and the Con Fire notification form receipt; inferred from what the submittal/checklist package requires rather than a standalone 'bring to inspection' list. 60% · inference from published checklist
• Does the inspector verify labels and listings? Yes 80% · department form

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 (signed permit/inspection card); no separate Certificate of Occupancy is issued for a residential PV alteration to an existing dwelling. 65% · inference
• Who notifies the utility for PTO? Not confirmed from a San Pablo-specific document; under PG&E's general DG interconnection process the installer/customer typically submits the PTO request once the AHJ final inspection is cleared, but this was not independently verified against a San Pablo-specific source this run. 45% · utility tariff (inference)
• Is there a re-inspection fee? $171/hour 88% · fee schedule
• How are corrections issued and cleared? A written correction notice detailing all deficiencies and any additional required information/documentation is sent to the applicant for resubmission. 85% · codified ordinance
