City of West Sacramento

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% · authority's own page (via Wayback, see note)
• What does this authority permit itself, and what does it delegate? Both 90% · ordinance
• 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% · published checklist
• Is a HOA or architectural approval required first? No -- California's Solar Rights Act, Civil Code §714, bars an HOA from imposing conditions that significantly increase the cost of a solar system or that effectively prohibit installation; the city's own permit process (SolarAPP+/Accela) does not list HOA sign-off as a submittal requirement. 65% · state statute
• Is a wind or windstorm certification required? No 65% · ordinance (full text read)

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 60% · published checklist
• Must the contractor be registered with this authority before applying? Yes 90% · published checklist
• Is a homeowner permitted to self-install and self-permit? Yes 55% · published checklist / applications 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? Signed owner/contractor contract; site plan (to scale) showing property, dwelling, side yards, north arrow, panel locations, panel count, electrical service/junction box/disconnect/inverter locations; single-line electrical diagram (array config/wiring, combiner box, conductor & conduit sizes, grounding, inverter model, disconnect location, panel/sub-panel size, point of connection); PV module & inverter spec sheets; equipment mounting specifications; signage details per manufacturer and CEC; and a design-professional or electrical-contractor signature plus roof-structural-adequacy verification. 95% · published checklist
• Is a site plan required, and what must it show? Yes -- a site plan to scale showing the property, dwelling location, side yards, north arrow, panel locations on roof or in yard, total panel count, and the location of electrical service, junction boxes, system disconnect and inverter. 95% · published checklist
• Is a one-line / three-line diagram required? Yes 95% · published checklist
• Are string and conductor calculations required? Yes 70% · published checklist
• Is a structural PE stamp required, and at what threshold? No PE stamp strictly required -- the checklist accepts verification from 'a California licensed engineer, architect, or general contractor' that the existing roof framing is structurally adequate for the added PV load; no valuation/size threshold is stated. 90% · published checklist
• Is an electrical PE stamp required, and at what threshold? No PE stamp strictly required -- submittals must bear the signature of either 'the design electrical engineer or electrical contractor'; no threshold stated. 85% · 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? Accela Citizen Access (ACA), branded 'Citizen Access' -- https://aca-prod.accela.com/WESTSAC/Default.aspx (also aliased at access.cityofwestsacramento.org/CitizenAccess), used together with the SolarAPP+.org portal for the automated code-compliance step. 95% · portal landing page
• Can the whole application be completed online? Yes -- for SolarAPP+-eligible residential retrofit PV, the entire path (design registration, automated review, permit application, payment, job-card issuance, inspection scheduling and results) is completed online through solar-app.org plus Accela Citizen Access. 88% · authority's own page (via Wayback)

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? No published standard turnaround found for a conventional plan-check; for SolarAPP+-eligible systems (the majority of residential retrofit PV), the city's own page describes 'instant permitting' via automated code-compliance review. 70% · authority's own page (via Wayback)
• How long is an issued permit valid before it expires? 365 days (12 months) from issuance if no inspection has been conducted, per CBC §105.5.1 / CRC §105.2 as applied by the city. 90% · department handout
• Which utility handles interconnection here? PG&E (Pacific Gas & Electric Company) -- bundled service, no Community Choice Aggregation. 90% · authority's own page (via Wayback)
• Where does the utility sit in the sequence? Parallel/After permit -- PG&E's interconnection (EGI/NEM) application can be filed in parallel with the city permit, but PG&E will not connect/energize (grant PTO) until the AHJ permit has passed final inspection. 65% · utility service manual (Greenbook)

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 75% · authority's own page (via Wayback) + adopted-code excerpt
• Which building code edition is in force? 2025 California Building Code (Title 24, Part 2), effective 1 Jan 2026; the 2022 California Building Code (adopted by Ordinance 22-20) governed permit applications submitted before that date and remains applicable only to permits filed under the prior cycle. 95% · authority's own page (via Wayback)
• Which fire code edition is in force? 2025 California Fire Code (Title 24, Part 9), effective 1 Jan 2026, superseding the 2022 California Fire Code adopted by Ordinance 22-20 §15.14.010. 90% · authority's own page (via Wayback)
• Are there local amendments to any of the above? Yes 85% · ordinance
• What is the installation judged against? The 2025 California Building, Residential, Electrical, Fire, Energy and Green Building Standards Codes (Title 24) as locally amended by Ordinance 22-20 (carried forward pending any 2025-cycle amendment ordinance), plus the city's Roof Mount Photovoltaic Checklist. 85% · authority's own page (via Wayback)

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 City of West Sacramento 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 NEC 690.12 as carried by the 2025 CEC (in force since 1 Jan 2026). Flag: the city's own 'Roof Mount Photovoltaic Checklist' (PDF dated 2 Jan 2023) still tells applicants to follow 'applicable 2022 CEC requirements' for signage/rapid-shutdown-adjacent labeling and has not been visibly updated to the 2025 CEC cycle now in force -- a stale reference of exactly the kind flagged as consequential for labelling. 65% · published checklist (stale) cross-checked against current code-adoption page

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? CEC-compliant PV placards per the equipment manufacturer's listed installation instructions (the checklist defers to 'applicable... CEC requirements' rather than itemising each placard); additionally PG&E requires its own engraved placard on the metering equipment where a fusible AC disconnect is installed ahead of the main breaker for a line/supply-side-tapped system. 65% · published checklist + utility service manual
• Does the authority specify placard wording of its own? No 70% · published checklist
• Does the UTILITY specify placards beyond the AHJ's? Yes -- PG&E's Greenbook requires an engraved placard on the metering equipment indicating a line/supply-side connection wherever a fusible AC disconnect is installed ahead of the main breaker, in addition to whatever the AHJ requires. 85% · utility service manual (Greenbook)
• Where must the labels be placed? At the PV disconnect/service-equipment location identified on the required one-line diagram; where PG&E's line/supply-side-tap placard applies, it must be 'installed on the metering equipment' itself. 70% · published checklist + utility service manual

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? No AC disconnect is required at all for a typical residential self-contained, socket-based, ≤320A single-phase inverter-based system (the common rooftop PV case) unless the utility connection is a line/supply-side tap, in which case a fusible AC disconnect is required ahead of the main breaker, after the meter. Any other (non-self-contained/transformer-rated) panel configuration requires a PG&E-approved AC disconnect. 75% · utility service manual (Greenbook)
• Must equipment be on a specific approved list? Yes 95% · authority's own policy bulletin (via Wayback)
• Is a ground mount treated as a structure? Likely yes 55% · inference from published checklist list
• Is a specific mounting system or attachment spacing required? The mounting-specification submittal must show the specific mounting arrangement for the given roof framing/covering and must leave 'sufficient space to allow for the removal of debris and allow for water drainage'; no fixed universal spacing dimension (e.g. a specific inch figure) is stated -- it is judged against the manufacturer's engineered mounting details case by case. 80% · 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? Portal (Accela Citizen Access, online scheduling for logged-in accounts), Phone (916-617-4691), or Email (bldginsp@cityofwestsacramento.org). 95% · department handout
• How much notice is required? One business day -- requests must be received by 4:30 p.m. the business day before the requested inspection date; next-business-day scheduling is 'not guaranteed and subject to availability.' 90% · department handout
• Are same-day or AM/PM windows offered? Yes -- AM (typically 8:00 a.m.-12:00 p.m.) or PM (typically 1:00-4:00 p.m.) windows are offered; no same-day inspection option is published (next-business-day is the minimum lead time). 90% · authority's own page (via Wayback)

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 88% · department handout
• If delegated, to whom? N/A -- not delegated (see Q52). 88% · department handout

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? The published 'Inspection Requirements (Typical)' sequence (footing/foundation, slab/under-floor, lowest-floor elevation, frame, lath/gypsum, fire-resistant penetrations, energy-efficiency, other/special inspections, then final) describes general new-construction inspections; it is not PV-specific. For a typical residential retrofit PV project the practical sequence appears to be a single Final inspection (job card + approved plans on site), since no separate rough-in stage is called out for PV anywhere the city publishes. 55% · department handout
• Is a rough-in or mid-roof inspection required? Not specified for retrofit PV -- the general new-construction 'frame inspection' stage in the typical sequence does not appear to be triggered by a roof-mount retrofit PV permit, which the city's own materials describe as needing only a job-card/final inspection. 50% · department handout

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, for the SolarAPP+ track 90% · authority's own page (via Wayback)
• What must be on site at inspection? The approved plans (including all calculations and energy forms) and the job card, posted in a conspicuous place for the inspector's signature; failure to have plans on site is stated to result in a failed inspection. For SolarAPP+ permits, the SolarAPP+ Inspection Checklist must also be on site. 95% · department handout
• Does the inspector verify labels and listings? Likely yes 65% · authority's own policy bulletin (via Wayback)

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 65% · department handout
• Who notifies the utility for PTO? Installer 60% · utility service manual (Greenbook) + standard NEM practice
• How are corrections issued and cleared? A correction notice is left with the job card on a failed inspection; it is the permit holder's responsibility to make the required corrections and recall (re-request) the inspection through the same portal/phone/email channels. 90% · department handout
