City of King 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 95% · municipal code
• 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% · fee schedule
• Is there a separate electrical permit, or is it combined? Combined 80% · permit application form
• Is a HOA or architectural approval required first? No, for the R-1 and R-2 districts where most single-family rooftop solar would be installed. Conditionally Yes for R-3, R-4, H-S, C-N, M and P-D districts. 75% · municipal code
• Is there a historic-district review? Conditional -- only within the mapped Historic Downtown Corridor area. KCMC 17.50.070-17.50.077 (added Ord. 832, 2024) impose a design/color review process for exterior alterations to buildings within the Historic Corridor Revitalization Plan boundary; properties outside that boundary are not subject to it. 72% · municipal code
• Is a wind or windstorm certification required? No 75% · municipal code
• Is there a system-size cap on residential generation? None codified. No kW-based size cap, ministerial-eligibility gate, or system-size threshold for residential solar appears anywhere in Title 12 (Buildings), Title 17 (Zoning) or Title 5 (Business Licenses). 82% · 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 82% · permit application form
• Must the contractor be registered with this authority before applying? Yes 85% · municipal code
• Is a homeowner permitted to self-install and self-permit? Yes 88% · permit 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.

• How many copies, and in what format? Electronic, via the Citizenserve online portal -- the City's own Building Permit Review Process flow chart states 'Building Applications submitted via Citizenserve portal. Uploading of any supporting documents for plan check review via Citizenserve.' No copy-count or paper-format requirement is stated anywhere for building permits generally. 68% · published process chart

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? Citizenserve Online Portal (Building Permit application type). 92% · department FAQ
• Can the whole application be completed online? Yes 88% · department FAQ
• What does a residential solar permit cost? Residential: $497.00 flat up to 15 kW AC nameplate, plus $16.80 per additional kW above 15 kW. (Commercial: $1,102.00 up to 50 kW, tiered above that -- not applicable to residential.) 90% · fee schedule
• How is the fee calculated? Tiered 85% · fee schedule
• Is there a separate plan-check fee? No 58% · 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? Approximately 2 weeks (a stated 'two (2) weeks plan check review period') for applications routed to the Project Review Committee (PRC), with weekly status updates on Tuesdays at the PRC meeting. 72% · published process chart
• How long is an issued permit valid before it expires? 2 years from issuance; void if work is not commenced within 180 days, or if suspended/abandoned (no progress inspection) for more than 180 days. 88% · municipal code
• Which utility handles interconnection here? PG&E (Pacific Gas & Electric Company) is the wires/interconnection utility. The City of King ALSO operates its own Community Choice Aggregator, 'King City Community Power,' which purchases/provides generation while PG&E continues to deliver and bill. 92% · fee schedule
• Where does the utility sit in the sequence? Parallel (inferred) 55% · 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 (based on the 2024 IBC) and 2025 California Residential Code (based on the 2024 IRC), both adopted by Ord. 840, 12/9/2025, effective for permit applications made on or after 1 Jan 2026. 95% · municipal code
• Which fire code edition is in force? 2025 California Fire Code, based on the 2024 International Fire Code. 95% · municipal code
• Are there local amendments to any of the above? Yes -- extensive local amendments in the same Ord. 840 (12/9/2025): CBC Chapter 1 administrative amendments (permit expiration/fees/board of appeals), CFC amendments including the solar/PV placarding section (12.04.080(e)(28)-(29)) and dozens of fire-alarm/sprinkler amendments, IPMC amendments, plus a standalone Construction & Demolition materials-diversion program (KCMC 9-4 series) amending the Green Building Code. 92% · municipal code
• What is the installation judged against? General compliance with the adopted 2025 California Electrical Code (based on the 2023 NEC) and the other adopted Technical Codes (KCMC 12.04.020 defines 'Technical Codes' to include the CBC/CEC/CFC/etc.) -- no solar-specific published standard exists since King City has no PV-specific submittal handout. 65% · municipal code

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? Hip/valley layout: modules may not be placed closer than 1.5 feet to a hip or valley if modules are on both sides of it (may be placed directly adjacent if only one side of an equal-length hip/valley has modules) -- KCMC 12.04.080(e)(29)(B) (CFC Sec.1205.2.1.4). The same amendment DELETES CFC Sec.1205.2.1 Exceptions 1 and 2 entirely, meaning the base (unamended) 2025 CFC clear-access-pathway and setback figures apply with no local exception carve-outs. 85% · municipal code

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? Rapid shutdown is required as a matter of the wholesale-adopted 2025 California Electrical Code (based on the 2023 NEC, Sec.690.12), which King City adopts with no carve-out; no City document names '690.12' or 'rapid shutdown' explicitly. 68% · municipal code

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? Per KCMC 12.04.080(e)(28) (CFC Sec.1205.1.1, added by Ord. 840, 12/9/2025): (1) a placard reading 'SOLAR DISCONNECT INSIDE PANEL' on the main service disconnect panel; (2) a label reading 'SOLAR DISCONNECT' at the circuit breaker controlling the inverter/PV controller; (3) additional signage (wording left to the fire code official) at any secondary power source (battery/generator) shutoff switch; (4) installer name/emergency-phone signage adjacent to the main disconnect. 96% · municipal code
• Does the authority specify placard wording of its own? Yes 96% · municipal code
• Does it specify letter height, colour or material? Yes -- Main-panel placard: red background, white capital letters AT LEAST 3/4 INCH in height, non-serif font, weather-resistant durable plastic with engraved letters (or other approved material). Circuit-disconnect label: contrasting-color capital letters at least 3/8 inch, non-serif font, durable adhesive material. 96% · municipal code
• Where must the labels be placed? Main service disconnect panel exterior (SOLAR DISCONNECT INSIDE PANEL placard); adjacent to the circuit breaker controlling the inverter/PV controller (SOLAR DISCONNECT label); at/adjacent to any secondary power source (battery/generator) shutoff switch; adjacent to the main disconnect (installer name/phone signage). 92% · municipal code

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.

• Are batteries permitted, and under what conditions? Yes, with conditions. King City's Fire Code amendments address batteries only via a signage requirement: where PV is interconnected to 'battery systems, generator backup systems, or other secondary power systems,' additional signage acceptable to the fire code official is required at the secondary-power-source shutoff switch (KCMC 12.04.080(e)(28)(3)). No separate battery/ESS chapter (CFC Chapter 12 Secs.1206/1207) was locally amended -- confirmed absent (zero hits for 'battery,' 'energy storage' or 'BESS' beyond that one signage clause) -- so the base, unamended 2025 CFC ESS provisions govern beyond signage. 80% · municipal code
• Is there a separate ESS permit or inspection? No distinct ESS/battery permit type or fee line appears in the current Master Fee Schedule (only the single 'Solar Energy System' line and general Building/Electrical/Mechanical/Plumbing permit categories) -- a battery-paired system appears to be processed under the standard building/electrical permit rather than a separately named ESS permit or inspection. 68% · fee schedule
• Is a ground mount treated as a structure? Not explicitly addressed. King City's Zoning Title 17 has no PV or ground-mount-specific provision anywhere (control-checked absence -- zero hits for 'photovoltaic,' 'ground mount' or 'renewable' across the full 609,070-character Title 17 text, against positive controls 'height'=93 and 'accessory'=92 hits). By inference, a freestanding ground-mounted array in an R district would likely be captured under the general accessory-building rules of KCMC 17.48.140 (rear-half-of-lot siting, 10-ft separation from dwellings, 4-ft side setback), but this is inference, not a stated rule. 58% · municipal code

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, fax, email, or the Citizenserve online portal. 90% · department page
• How much notice is required? Requests made before 4:00 p.m. are normally scheduled for the next business day (effectively about 1 business day's notice). 82% · department page
• Are same-day or AM/PM windows offered? No AM/PM window or same-day service is offered; the City states inspections 'are performed between 8 am and 5 pm, Monday through Thursday' -- notably, no Friday inspections -- 'other days and times by special request' (a special-inspection fee may apply). 85% · 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 78% · department page
• If delegated, to whom? Not applicable for residential solar -- performed in-house by the Building & Safety Department. (For unrelated commercial/multi-family/assembly annual FIRE inspections only, the City delegates to Carmel Fire Protection Associates, named staffer Fire Marshal Art Black.) 75% · 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.

Nothing recorded for City of King City on this step yet — 2 questions checked and found unpublished. The guidance above is general.

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? No dedicated solar/PV inspection checklist was found published. A general 'Handout 34 - Required Inspections' exists but is explicitly scoped to 'New Single Family Dwellings' new construction (foundation, framing, rough trades, final), not a PV retrofit-specific checklist. 65% · published handout
• What must be on site at inspection? The City's approved plans and the permit inspection card must remain on the job site for use by City inspection personnel. 88% · permit application 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 (Inspection) 62% · published handout
• Who notifies the utility for PTO? Installer (inferred) 55% · municipal code
• How are corrections issued and cleared? Plan-check comments/corrections are routed to the applicant for resubmittal (uploaded back into Citizenserve); Administrative Support Staff then routes the revision back to the Project Review Committee for review. The permit is issued only after final corrections are made and plans are approved by each reviewing department. 80% · published process chart
