Kings County

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% · code of ordinances
• What does this authority permit itself, and what does it delegate? Both 90% · code of ordinances
• Is a permit required for a residential rooftop PV system? Yes 98% · department bulletin
• Is there a separate electrical permit, or is it combined? Combined (administratively) — one solar application yields all required permits together 72% · code of ordinances
• Is a HOA or architectural approval required first? No 80% · department bulletin
• Is there a historic-district review? No 75% · department bulletin
• Is a Specific Use Permit or Council approval ever required? Not required for qualifying (≤10kW AC) systems — Planning/Council review is expressly waived; unclear whether a non-qualifying (larger/ground-mount) system would ever trigger an SUP, since no county document addresses that scenario. 62% · department bulletin
• Is there a system-size cap on residential generation? No hard cap — 10 kW AC is only the eligibility threshold for the expedited/streamlined process; larger residential systems are still permittable through standard (non-expedited) review. 88% · checklist

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% · code of ordinances
• Must the contractor be registered with this authority before applying? No 68% · form
• Is a homeowner permitted to self-install and self-permit? Yes 72% · permit portal

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? Permit application form; site/roof plan showing panel layout, access pathways, fire classification and label locations; single-line diagram (via the applicable Standard Plan) or, for non-qualifying systems, engineer-stamped drawings; Structural Criteria form (or engineer-stamped structural calcs if it fails); proof of equipment listing. 88% · department bulletin
• How many copies, and in what format? Electronic only — the CDA 'has shifted from accepting paper applications for permits to only digital applications'; submit via the online portal or by email to kcgc.building@co.kings.ca.us. 85% · department page
• Is a site plan required, and what must it show? Yes — a site/roof plan showing owner/address/APN, north arrow, adjacent streets, setback dimensions to structures/well/septic/propane, easements (general Ch.5 plan requirements), plus for solar specifically: roof layout, PV panel/module locations, approximate location of roof access points, code-compliant access pathways, PV fire classification, and locations of all required labels/markings. 90% · department bulletin
• Is a one-line / three-line diagram required? Yes 90% · standard plan
• Are string and conductor calculations required? Yes 75% · standard plan
• Is a structural PE stamp required, and at what threshold? Only if the array fails the county's prescriptive Structural Criteria checklist (roof condition, framing, anchor spacing/embedment) — then 'project-specific drawings and calculations stamped and signed by a California-licensed civil or structural engineer' are required. No threshold expressed as a weight/size number; it's pass/fail against the prescriptive checklist. 92% · checklist/form

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? Kings County Online Permit Center (cdapermits.countyofkings.com) 95% · portal landing page
• Can the whole application be completed online? Yes 82% · portal landing page
• What does a residential solar permit cost? Not a flat fee — building permit fee 'Per CBC' (valuation table) + electrical permit 'Per CEC' (valuation table) + a fixed $80 'PV Solar data processing/Permit' Public Works add-on. No single dollar figure is published for a typical residential system. 88% · fee schedule
• How is the fee calculated? Valuation (building & electrical portions) plus a flat $80 add-on fee 88% · fee schedule
• Is there a separate plan-check fee? Yes 68% · 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? 5 business days (non-over-the-counter); qualifying standard-plan submittals may be approved over the counter same-day 76% · department bulletin
• Which utility handles interconnection here? Southern California Edison (SCE) 76% · CPUC filing (secondary), corroborated by https://energycenter.org/sites/default/files/docs/nav/programs/smp/20.%20SCE%20Service%20Territory%20Cities.pdf listing
• Where does the utility sit in the sequence? No dependency for permit issuance / parallel — utility interconnection approval is a separate track the applicant must pursue on their own 85% · code of ordinances

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 (as adopted within the current 2025 California Electrical Code cycle) 85% · portal notice + code auto-adoption clause
• Which building code edition is in force? 2025 California Building Code (13th edition cycle), effective 1 Jan 2026 85% · portal notice + code auto-adoption clause
• Which fire code edition is in force? 2019 California Fire Code (Ord. No. 694, adopted 12/17/2019) — the last fire-code-specific ordinance found 65% · code of ordinances
• Are there local amendments to any of the above? Yes 90% · code of ordinances
• What is the installation judged against? The currently-adopted California Building/Electrical/Plumbing/Mechanical Codes (Title 24, via the county's self-updating adoption clauses) plus CEC Articles 690 & 705, CRC §R331 (fire pathways), and CFC §605.11.1 for PV-specific markings. 82% · standard plan

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? Clear access pathways and roof access points required, per checklist, but Kings County does not publish its own numeric pathway/setback dimensions — it points applicants to the State Fire Marshal's Solar PV Installation Guideline for examples. 78% · department bulletin

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 (flows from the currently-adopted 2023 NEC/2025 CEC cycle, NEC 690.12); Kings County's own standard-plan documents do not use the phrase 'rapid shutdown' anywhere — verified with a positive control ('electrical': 3 hits) and a fabricated control ('zzqqx': 0 hits) to confirm the search itself was working, not a broken query. 75% · code adoption clause (inference)

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? PV System AC Disconnect placard; PV System DC Disconnect placard; 'Dual Power Sources' warning at the main service panel; electric-shock-hazard warning at the inverter; 'Photovoltaic Power Source' warning at junction/combiner boxes and along exposed conduit (marked every 10 feet). 90% · standard plan
• Does the authority specify placard wording of its own? No 82% · standard plan
• Is a site plan / facility map placard required, and what must it show? Yes — a roof diagram/facility map showing panel layout, roof access point location, code-compliant access pathways, PV fire classification, and locations of all required labels/markings. 85% · department bulletin
• Where must the labels be placed? At the PV system AC and DC disconnects, at the inverter, at junction/combiner boxes, along exposed conduit runs (every 10 ft), and at the main service panel. 88% · standard plan

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 90% · standard plan
• Are batteries permitted, and under what conditions? Batteries/ESS are excluded from the expedited path — eligibility checklist item D requires the system be 'utility interactive and without battery storage.' Systems with batteries must go through standard (non-expedited) review; specific conditions for that path were not found in the documents reviewed. 82% · checklist
• Is a specific mounting system or attachment spacing required? Yes — prescriptive lag-screw/anchor spacing table (Table 1, by roof slope and rafter spacing), 5/16" diameter lag screws with 2.5" embedment (or manufacturer-rated fastener) as the default attachment method. 92% · checklist/form

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 or electronic/web request 90% · department bulletin
• Are same-day or AM/PM windows offered? Not offered as such — requests received during business hours are 'typically scheduled for the next business day,' with no same-day or AM/PM window language found. 62% · department bulletin

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 95% · code of ordinances

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? One combined building-and-fire final inspection after installation is complete (expedited path); a follow-up re-inspection is authorized if the first fails. 90% · code of ordinances
• Is a rough-in or mid-roof inspection required? No 88% · code of ordinances

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 82% · department bulletin
• Does the inspector verify labels and listings? Yes 82% · department bulletin

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.

• Who notifies the utility for PTO? Installer 85% · code of ordinances
• How are corrections issued and cleared? Written correction notice detailing all deficiencies and any additional information needed for expedited approval. 85% · code of ordinances
