City of Chico

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 90% · department page
• What does this authority permit itself, and what does it delegate? Both 88% · municipal code
• Is a permit required for a residential rooftop PV system? Yes 95% · fee schedule
• Is there a separate electrical permit, or is it combined? Separate 85% · municipal code
• Is a HOA or architectural approval required first? No 60% · municipal code
• Is there a historic-district review? Yes, conditionally 68% · 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 85% · municipal code
• Must the contractor be registered with this authority before applying? Yes 78% · department page
• Is a homeowner permitted to self-install and self-permit? Yes 85% · municipal code

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? Digital only — no paper copies required 80% · department page
• Is a structural PE stamp required, and at what threshold? No fixed weight/height threshold found; 16.10.060.C gives the building official discretion to require plans/calculations be prepared by a licensed engineer or architect on a case-by-case basis (not solar-specific). 55% · municipal code

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? eTRAKiT (hosted at chico.csqrcloud.com/community-etrakit) 95% · portal landing page
• Can the whole application be completed online? Yes 82% · portal landing page
• What does a residential solar permit cost? $450 flat (systems ≤15 kW); $500 plus $15 per kW above 15 kW (systems >15 kW). Separate Ground Mount Solar racking permit = $876. 95% · fee schedule
• How is the fee calculated? Tiered 92% · fee schedule
• Is there a separate plan-check fee? No separate plan-check fee for a standard over-the-counter residential solar permit (the $450/$500+ fee is listed under 'OVER THE COUNTER PERMITS'); BUT the schedule notes 'Plan Check and applicable fees may be required for systems exceeding 40 lbs/sf OR for systems being installed on a Conventional Framed Roof' — in that case the general Plan Check & Inspection fee ($282/hr) applies on top. 75% · 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.

• How long is an issued permit valid before it expires? 180 days from issuance if work has not commenced, or 180 consecutive days of suspension/abandonment after commencement (extendable once by up to 180 days for cause). A lapsed permit may be renewed within one year at 50% of the original building permit fee if no plan changes. 92% · municipal code
• Which utility handles interconnection here? Pacific Gas & Electric (PG&E) 62% · utility company page

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 (as incorporated into the 2025 California Electrical Code) 90% · municipal code
• Which building code edition is in force? 2025 California Building Code (Part 2, Title 24 CCR) 95% · municipal code
• Which fire code edition is in force? 2025 California Fire Code (Part 9, Title 24 CCR), which amends/repeals sections of the 2024 International Fire Code 95% · municipal code
• Are there local amendments to any of the above? Yes — but concentrated in the Fire Code, not building/electrical/residential 85% · municipal code
• What is the installation judged against? The 2025 California Electrical Code (Title 24, Part 3) as adopted in Chapter 16R.04 88% · 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.

Nothing recorded for City of Chico 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 per NEC 690.12, as incorporated into the 2025 CEC (2023 NEC cycle) 75% · adopting ordinance (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.

• Does the authority specify placard wording of its own? No 62% · municipal code (absence)

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.

• Is a ground mount treated as a structure? Yes 88% · fee schedule

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 80% · portal page
• How much notice is required? Request by 3:00 PM for next-business-day inspection 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 75% · municipal code

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 Chico 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.

• What must be on site at inspection? An inspection record card posted at a conspicuous location on-site (required from permit issuance until final approval); approved plans/specifications should be available on-site since a fee may be assessed if they are not ('approved plans and specifications for such work are not readily available to the building official at the work site'). 75% · municipal code

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? $281.00 (Construction-Reinspection Fee, 1/2-hour minimum) — charged for more than two requests to inspect the same work item 92% · fee schedule
