City of Chino Hills

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 page
• What does this authority permit itself, and what does it delegate? Both 88% · authority's own page + fee schedule
• Is a permit required for a residential rooftop PV system? Yes 96% · authority's own page
• Is there a separate electrical permit, or is it combined? Combined 75% · fee schedule
• Is a HOA or architectural approval required first? No 68% · authority's own page
• Is a wind or windstorm certification required? No 55% · authority's own page (absence) + general CA regulatory context
• Is a Specific Use Permit or Council approval ever required? No — not required for a standard by-right residential rooftop or ground-mounted PV permit. 60% · authority's own page

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 80% · fire district plan-check requirements (PDF)
• Must the contractor be registered with this authority before applying? No (city); Yes (fire district) 75% · authority's own page + fire district page
• Is a homeowner permitted to self-install and self-permit? Yes 82% · fire district plan-check requirements (PDF)

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? SolarApp+ path: SolarApp+ approval packet + signed Smoke/CO Detector-Alarm form + Chino Valley Fire District (CVFD) approved plans, then City permit application with fees. CVFD's own submittal (required regardless of SolarApp+ use) requires: full dimensional site plan (property lines, structures, streets/alleys, setbacks, compass point); roof plan showing array/panel layout, fire setbacks, fire access pathways, conduit runs, main electrical service and inverter locations; total roof area and % covered by panels; a signage sheet showing required labeling per CEC/CFC; equipment specs/manufacturer cut sheets; and a set of wet-stamped structural calculations. 88% · fire district plan-check requirements (PDF) + authority's own page
• How many copies, and in what format? Electronic PDF only — no physical copies. 85% · fire district plan-check requirements (PDF)
• Is a site plan required, and what must it show? Yes — a full dimensional site plan is required reflecting property lines, all structures, streets, alleys, setbacks, and point of compass. 88% · fire district plan-check requirements (PDF)
• Is a one-line / three-line diagram required? Yes (functional equivalent) — a roof plan is required reflecting the array/panel layout, all conduit runs, and the locations of the main electrical service and inverter. 68% · fire district plan-check requirements (PDF)
• Is a structural PE stamp required, and at what threshold? A set of wet-stamped structural calculations is required with every residential PV submittal to the fire district (no stated size/weight threshold — CVFD's document says the calcs are 'used for reference only' by the fire district, implying the actual structural adequacy determination is the City Building Division's). 65% · fire district plan-check requirements (PDF)

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? Virtual Development Services (VDS) — a Tyler Technologies EnerGov Self Service portal at eplselfservice.chinohills.org. 92% · portal landing page
• Can the whole application be completed online? Yes 80% · authority's own page
• What does a residential solar permit cost? City: $450.00 flat (Photovoltaic Permit, Single-Family, roof- or ground-mounted) plus a 6% Technology Fee and a 0.08%-of-valuation General Plan Surcharge Fee. Fire district (Chino Valley Fire District, a mandatory separate permit): $280.00 flat ('Solar Residential', fee code 1810). Combined baseline cost ≈ $730 plus the percentage surcharges. 85% · fee schedule
• How is the fee calculated? Flat 85% · fee schedule
• Is there a separate plan-check fee? No separate plan-check fee is charged up front — it is bundled into the $450 City PV permit fee. A $538 'Plan Check Re-Submittal' fee applies only after 3 review cycles. 78% · 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? Fire district (CVFD, the gating review): same-day if submitted via the online portal or email between 8-11 a.m. on a Tuesday or Thursday (reviewed 1-3 p.m., permit issued same day); otherwise CVFD's regular queue is 7-10 business days. The City's own building/electrical plan-review turnaround for the PV permit itself is not separately published. 72% · fire district plan-check requirements (PDF)
• Which utility handles interconnection here? Southern California Edison (SCE) 95% · authority's own page
• Where does the utility sit in the sequence? Parallel to permitting, with SCE's Permission-to-Operate (PTO)/energization occurring after construction and City final inspection are complete. 62% · utility interconnection 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 amended, incorporated into the 2025 California Electrical Code) 88% · adopting ordinance
• Which building code edition is in force? 2025 California Building Code (Volumes 1 & 2) and 2025 California Residential Code 95% · adopting ordinance
• Which fire code edition is in force? 2022 California Fire Code (with 2021 IFC portions), per Chino Valley Independent Fire District Ordinance No. 2022-03 88% · adopting ordinance (OCR'd scan)
• Are there local amendments to any of the above? Yes 82% · adopting ordinance
• What is the installation judged against? The 2025 California Electrical Code (2023 NEC as amended) and 2025 CBC/CRC for the City permit, plus the 2022 California Fire Code and CVFD's own PV plan-check requirements (fire setbacks, access pathways, signage-per-code) for the fire district's separate, gating permit. 82% · fire district plan-check requirements (PDF)

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? Governed by the base 2022 California Fire Code (Section 605.11 rooftop PV fire-classification/access requirements) as adopted by CVFD Ordinance No. 2022-03; no CVFD-specific numeric ridge-setback amendment was found. CVFD's submittal checklist requires the roof plan to show 'fire setbacks, fire access pathways' but does not restate different numbers of its own. 62% · adopting ordinance (OCR'd scan) + fire district plan-check requirements (PDF)

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 — required to NEC 690.12, as incorporated by the 2025 California Electrical Code (based on the 2023 NEC). 85% · adopting ordinance (edition) + NEC 690.12 (state-adopted)

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? Placards/labels required at the service equipment per the California Electrical Code (NEC Article 690 marking requirements) and California Fire Code — CVFD requires a dedicated 'signage sheet' in the submittal showing all required labeling before it will approve the plan. 75% · fire district plan-check requirements (PDF)
• Does the authority specify placard wording of its own? No 80% · fire district plan-check requirements (PDF)
• Does it specify letter height, colour or material? Not specified by the City or fire district for PV service-equipment placards generally; the utility (SCE) does specify letter height for its own metering labels — 'All lettering shall be a minimum one-quarter inch in height' for Net Generation Output Metering tags. 70% · utility Electrical Service Requirements manual
• Is a site plan / facility map placard required, and what must it show? Yes (functional equivalent) — the roof plan required for fire-district approval must show the array/panel layout, fire setbacks, fire access pathways, conduit runs, and main electrical service/inverter locations, i.e. the facility-map information NEC 690/705.10 firefighter-safety placarding is meant to convey. 70% · fire district plan-check requirements (PDF)
• Does the UTILITY specify placards beyond the AHJ's? Yes — SCE's Electrical Service Requirements (ESR) manual requires Net Generation Output Metering (NGOM) equipment to be permanently labeled 'Net Generation Output Metering' on a machine-engraved phenolic tag, plus 'Grid side'/'Generation side' conductor-direction markings, and signage on isolation/lockable disconnect devices for SCE's padlock provisions. 88% · utility Electrical Service Requirements manual
• Where must the labels be placed? NGOM labels: on the meter panel or immediately adjacent to the meter socket. The AC disconnect (where a Generation Meter Adapter is used): installed directly adjacent to the meter, connected via liquid-tight flexible conduit (2 ft minimum, 3 ft maximum). 82% · utility Electrical Service Requirements 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? Directly adjacent to the meter (utility requirement) — SCE requires 'a single, AC fuseable disconnect, with an external lockable handle... installed directly adjacent to the meter' where a Generation Meter Adapter is used, and more generally requires a disconnecting means with overcurrent protection at the meter location for every service. 85% · utility Electrical Service Requirements manual
• Must equipment be on a specific approved list? Partially — SCE maintains and references its own approved-equipment lists (UL Certified Power Control Systems, and pre-approved inverters) as part of Rule 21 review for certain interconnection types; no City- or CVFD-maintained 'approved equipment list' was found for the building/fire permits themselves. 65% · utility interconnection page
• Are batteries permitted, and under what conditions? Yes — batteries/ESS are permitted; the City's fee schedule carries a distinct 'Energy Storage System (not integrated with PV system) — $269.00' line, and CVFD's Master Fee Schedule carries a 'Special Equipment (batteries, ovens, dust, etc.) — $339.00' line (fee code 1620), separate from each agency's PV-specific fee. 75% · fee schedule
• Is there a separate ESS permit or inspection? Yes — an ESS not integrated with the PV system is a separately fee-coded item at both the City ($269) and the fire district ($339, 'Special Equipment'), implying a distinct review/inspection line from the PV permit itself. 72% · fee schedule
• Is a ground mount treated as a structure? Ambiguous/likely no separate structural 'accessory structure' treatment for permitting purposes — the City's fee schedule prices 'Photovoltaic Permit Residential - Ground Mounted' at the same $450 as roof-mounted, under the Electrical Permits section, rather than routing it through a distinct structural/accessory-building permit. 55% · 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 90% · authority's own page
• How much notice is required? Effectively next business day if requested by 2:00 p.m.; requests after 2:00 p.m. roll to the day following the next business day (e.g., after 2 p.m. Friday schedules for Tuesday). 88% · authority's own 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% · authority's own page
• If delegated, to whom? Not delegated for the building/electrical portion (City inspects that itself). The fire/life-safety portion is inspected by Chino Valley Independent Fire District, a separate special district with its own original jurisdiction over its own PV permit — not a delegation by the City but a coequal, gating agency. 75% · fire district 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? 1) CVFD PV plan review and CVFD permit issuance (must precede City permit — 'Each of these agencies will not issue building permits prior to approval and issuance of a permit from the Fire District'); 2) City building/electrical PV permit issuance via the VDS portal; 3) City field inspection(s) of the installed system; 4) (implied) CVFD field verification of its own permit conditions. 72% · fire district plan-check requirements (PDF)

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.

• Does the inspector verify labels and listings? Yes (inferred from practice) 68% · fire district plan-check requirements (PDF)

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 62% · utility interconnection page
• Is there a re-inspection fee? $336.00 90% · fee schedule
• How are corrections issued and cleared? Corrections are handled through the Virtual Development Services (EnerGov) portal; for the PV-specific revision path, the Residential Solar page states any revision to approved plans requires new approval from CVFD, from SolarApp+ (if that path was used), and from the Building & Safety Division before resubmission via the portal. 68% · authority's own page
