Suisun City

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% · authority's own department page
• What does this authority permit itself, and what does it delegate? Both 82% · authority's own department page
• Is a permit required for a residential rooftop PV system? Yes 90% · ordinance
• Is there a separate electrical permit, or is it combined? Combined 60% · fee schedule + ordinance inference
• Is there a historic-district review? Yes (administrative-level review) 88% · ordinance
• Is a wind or windstorm certification required? No 75% · ordinance, control-proven absence
• Is a Specific Use Permit or Council approval ever required? Yes, conditionally 85% · ordinance
• Is there a system-size cap on residential generation? 10 kW AC / 30 kW thermal cap for the expedited 'small residential rooftop solar energy system' pathway; system must also not exceed the maximum legal building height and must be on a single or duplex-family dwelling. This is a gate to the expedited path, not an absolute ceiling — larger systems simply route to standard plan review (not explicitly detailed in any document found). 90% · 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? Either 78% · ordinance
• Must the contractor be registered with this authority before applying? Yes 85% · ordinance
• Is a homeowner permitted to self-install and self-permit? Yes 78% · ordinance

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? General building-permit submittal package (from the 'Get a Building Permit' page / 'Requirements to Obtain a Building Permit' handout, ModDate 26 Jun 2024): permit application, electronic construction drawings (plot plan, foundation detail, framing detail, floor plan, 2-4 elevations), and Title 24 energy compliance. No solar-specific checklist was found published anywhere on the site (see not_found), despite SCMC 15.04.390(E)(1) requiring the building official to publish one. 70% · authority's own handout, dated
• Is a site plan required, and what must it show? Plot plan showing position of proposed project relative to existing buildings, property lines, and public utility easements, at 1/8"=1'0" minimum scale (general building-permit requirement; no solar-specific site-plan content — e.g. panel layout, fire-access pathways — is specified in any city document found). 65% · authority's own handout
• Is a structural PE stamp required, and at what threshold? No fixed valuation/size threshold is codified; SCMC 15.04.110(B) gives the building official discretion to require plans 'prepared and designed by an engineer or architect licensed by the state' where needed for code enforcement, and 15.04.120 requires state Building/Professional Code-compliant design only for occupancy groups A,B,E,F,H,I,M,S,R-1 (not R-3 single-family). 62% · ordinance

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 92% · authority's own department page
• Can the whole application be completed online? Yes 62% · portal landing page, inferred from platform type
• What does a residential solar permit cost? $196 flat (residential photovoltaic electrical permit fee) 85% · fee schedule
• How is the fee calculated? Flat 82% · fee schedule
• Is there a separate plan-check fee? No 58% · fee schedule inference

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? Same day (if the application meets the approved checklist) or within 3 business days for electronic applications after a complete application is received 90% · ordinance
• How long is an issued permit valid before it expires? 2 years (730 days) from date of issuance 78% · ordinance
• Which utility handles interconnection here? Pacific Gas & Electric (PG&E) 85% · adopted General Plan background report
• Where does the utility sit in the sequence? Parallel, with PTO gated on the AHJ's final inspection clearance 75% · 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? 2020 NEC (via the 2022 California Electrical Code), per the codified local adoption — SCMC 15.04.030(D). NOTE: this citation is codified through Ord. No. 801 (8 Aug 2023) and the code is codified through Supplement 23 / Ord. No. 820 (17 Jun 2025) with no visible newer building/electrical-code adoption ordinance; the statewide 2025 Title 24 cycle (2025 CEC, based on the 2023 NEC) took effect 1 Jan 2026 and applies automatically as a matter of state law even though the local codification text has not caught up. 68% · ordinance, with lag noted
• Which building code edition is in force? 2022 CBC (referencing 2021 IBC), per SCMC 15.04.030(A) — same code-cycle-lag caveat as Q29: statewide 2025 CBC took effect 1 Jan 2026 and the local ordinance text has not been updated to reflect it. 68% · ordinance, with lag noted
• Which fire code edition is in force? 2022 CFC (referencing 2021 IFC), per SCMC 15.04.030(H), together with Chapters 1, 2 and Appendices B, C, D, E — same code-cycle-lag caveat: statewide 2025 CFC took effect 1 Jan 2026 and the local text has not been updated. 68% · ordinance, with lag noted
• Are there local amendments to any of the above? Yes 90% · ordinance
• What is the installation judged against? The adopted 2022 California Electrical Code (2020 NEC) and the equipment/performance standards named in SCMC 15.04.390(D) — CEC, IEEE, and accredited testing laboratories (e.g. UL) — plus, for the expedited pathway, conformance to the checklist and standard plans in the current California Solar Permitting Guidebook per 15.04.390(E)(5). 75% · 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.

Nothing recorded for Suisun City on this step yet — 1 question checked and found unpublished. The guidance above is general.

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 under the adopted 2020 NEC (§690.12) via the 2022 CEC (SCMC 15.04.030(D)); no local amendment to this requirement was found. 78% · ordinance, inferred from adopted NEC edition

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.

• Does the UTILITY specify placards beyond the AHJ's? Yes, conditionally — a visible manual disconnect near the point of interconnection with markings/signage clearly indicating open and closed positions, when required by PG&E operating practices. 72% · utility tariff

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 82% · ordinance
• Is a ground mount treated as a structure? Yes, by inference 68% · ordinance, inferred from zoning definition
• Is a specific mounting system or attachment spacing required? Roof-mounted panels/thermal tanks must be mounted no more than 10 inches from the roof surface. 85% · ordinance (zoning design chapter)

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 (Tyler EnerGov self-service) or phone 82% · 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 75% · authority's own 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? For a small residential rooftop solar system eligible for the expedited pathway, only one consolidated inspection is required; general (non-expedited) construction follows the standard multi-stage sequence (foundation, underfloor, frame, insulation, sheetrock nailing, final) from the general building-permit handout. 82% · ordinance
• Is a rough-in or mid-roof inspection required? No 78% · ordinance, inferred

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.

• What must be on site at inspection? The Inspection Card must be on site at the time of inspection. 88% · authority's own department page

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.

• Is there a re-inspection fee? $130 per hour 82% · fee schedule
