City of Highland

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 85% · department page
• Is a permit required for a residential rooftop PV system? Yes 95% · department page
• Is there a separate electrical permit, or is it combined? Combined 60% · department page + fee schedule
• Is a HOA or architectural approval required first? No — not a city permitting prerequisite; HOA/architectural review is not listed in the submittal package, and CA Civil Code §714/§4600 (Solar Rights Act) limits HOA authority to disapprove residential solar. 60% · department page (absence) + state statute
• Is there a historic-district review? Yes, for structures designated Historic 90% · department page
• Is a Specific Use Permit or Council approval ever required? Planning Division approval (not full Council/SUP) is required before permit issuance for ground-mounted systems and for roof-mount on Historic-designated structures; no evidence found of a Specific Use Permit or Council hearing being required for typical residential rooftop PV. 75% · department page
• Is there a system-size cap on residential generation? No blanket city-wide generation-size cap found; the SolarAPP+ automated track is capped at 38.4 kW AC (eligibility ceiling for that pathway only — larger or ground-mount/ballasted systems route to standard plan check instead). 70% · department 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 75% · department page
• Must the contractor be registered with this authority before applying? Yes 80% · department page + application form
• Is a homeowner permitted to self-install and self-permit? Yes 60% · city 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.

• What documents make up a complete submittal? Building Permit Application; two (2) sets of plans + two (2) sets of structural calculations (in-person) or a single electronic upload of plans/calcs/product specs (electronic/SolarAPP+); signed Contractor Declarations (or Owner-Builder Declarations); current CSLB license verification; current city business-license verification; notarized Letter of Authorization if an agent signs for the contractor. 85% · department page
• How many copies, and in what format? In-person: two (2) sets of plans + two (2) sets of structural calculations, paper. Electronic/SolarAPP+: single digital upload (PDF) via the iWorq portal or solarapp.nrel.gov. 85% · department page
• Is a site plan required, and what must it show? A site/plot plan is required as part of the general building-permit submittal package ('Plot/Site design' among the plan sets), but no solar-specific site-plan content list (panel layout, setbacks, access pathways) is published. 55% · bulletin (dated May 2017)

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? iWorq permit portal (highlandcabuildingpermit.portal.iworq.net) for building/electrical/fire permits generally; SolarAPP+ (solarapp.nrel.gov) for eligible automated residential rooftop PV up to 38.4 kW AC. 90% · portal landing page
• Can the whole application be completed online? Yes 85% · department page
• What does a residential solar permit cost? $330 fixed fee plus $19 per kW above 15 kW (permit S-0189, plan review + inspection combined) plus a $95 general permit-application fee (S-0005). The schedule states this combination is kept under the state-mandated $450 cap for a residential system up to 15 kW. 90% · fee schedule (PDF, 'FEE COMP SPREADSHEET 2025 2026 Revised', ModDate 14 Oct 2025)
• How is the fee calculated? Tiered (flat base fee + per-kW increment above a threshold) 85% · fee schedule
• Is there a separate plan-check fee? No — the S-0189 line item is a single combined fee for 'Reviewing plans & calculations and conducting inspection'; there is no separate plan-check line for residential solar distinct from the inspection fee. 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.

• What is the stated plan-review turnaround? Electronic submittal: 1–3 business days, most same/next business day. In-person: expedited, 'no more than 1-2 days'. SolarAPP+: instant/automated. 90% · department page
• How long is an issued permit valid before it expires? 365 days / 12 months — permit expires/becomes invalid if work has not commenced within 12 months of issuance, or is suspended/abandoned for 12 months; the permittee must show progress with a passing inspection at least every 365 days. 85% · city form
• Which utility handles interconnection here? Southern California Edison (SCE) 90% · fee schedule
• Where does the utility sit in the sequence? After permit (utility release/energization follows city inspection sign-off, based on the general electrical-service-inspection process) 50% · fee schedule (general, not solar-specific)

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 (inferred as the 2025 California Electrical Code, statewide default effective 1 Jan 2026) — not independently confirmed against Highland's own adoption ordinance. 45% · inference (adopting ordinance unreachable — 403)
• Which building code edition is in force? 2025 CBC (statewide default effective 1 Jan 2026) — city's own Title 15 adoption/amendment ordinance not independently viewable. 45% · bulletin (dated May 2017) + statewide inference
• Which fire code edition is in force? 2025 CFC (statewide default effective 1 Jan 2026) — city's own bulletin confirms the Fire Code IS among the codes it has adopted, but gives no edition and the Title 15 ordinance text could not be retrieved (ecode360 403). 45% · bulletin (dated April 2017) + statewide inference
• Are there local amendments to any of the above? Yes — the city states it applies 'adopted City amendments' to the state codes in Municipal Code Title 15, though the specific amendment text could not be retrieved (ecode360 403). 60% · bulletin (dated May 2017)
• What is the installation judged against? The California Building, Electrical (per CEC/NEC), Mechanical, Plumbing, Fire, and Energy Codes as adopted by the California Building Standards Commission, with the city's own Title 15 amendments. 65% · bulletin (dated May 2017)

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 Highland 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.

Nothing recorded for City of Highland on this step yet — 1 question checked and found unpublished. The guidance above is general.

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? Not published — no placard/labeling specification found on the solar page, fee schedule, general submittal bulletin, permit-tips bulletin, or inspections page. 55% · absence across department page + fee schedule + bulletins

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? Not addressed in any published Highland document found; presumably governed by default 2022/2025 CRC/CFC energy-storage-system provisions (adopted by reference per the city's general code-adoption statement) with no local ESS-specific bulletin. 45% · absence, checked
• Is there a separate ESS permit or inspection? No separate ESS permit fee line is published in the Master Fee Schedule; whether ESS is folded into the standard building/electrical permit (S-0189/S-0269) or requires a distinct process is not documented. 50% · fee schedule (absence, checked)
• Is a ground mount treated as a structure? Yes — ground-mounted systems are treated differently from simple roof-mounts and require Planning Division approval before a building permit is issued. 75% · department page

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 (iWorq electronic inspection requests are the documented primary route), with phone and email also offered by the Building & Safety counter. 80% · department page
• Are same-day or AM/PM windows offered? Yes — AM (8am–noon) and PM (noon–5pm) windows Mon–Thu; Friday is AM-only; Fire Prevention inspections are AM-only Mon–Thu. Exact times are not guaranteed. 90% · 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% · department page
• If delegated, to whom? Not delegated — Highland's own Building & Safety Division performs the inspection in-house. 70% · 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 Highland 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 — there is no published generic inspection checklist; the FAQ states 'the required inspections are listed on the project job card,' i.e., generated per-permit rather than published as a standing document. 65% · FAQ page
• What must be on site at inspection? The job card, and the approved/stamped construction documents (plans); site access permission from an adult (18+); a ladder if roof access is needed (tied off/secured); any special access info (e.g., gate codes) noted in the request. 90% · department page
• Does the inspector verify labels and listings? Not documented — no published statement that the inspector specifically checks labels/listings. 45% · department page (silent on this specific item)

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? The inspector signs off the job card as a passed inspection (functions as the project's Final); no separate Certificate of Occupancy is described for a residential PV alteration. 55% · FAQ page
• Who notifies the utility for PTO? AHJ (inferred) — the city inspects the electrical service on-site and then faxes approval/denial to Edison, based on the general (non-solar-specific) service-inspection process. 50% · fee schedule (general, not solar-specific)
• Is there a re-inspection fee? $90 per half hour (or portion) for a second re-inspection (S-0335); the fee schedule does not indicate a charge for a first re-inspection. 80% · fee schedule
• How are corrections issued and cleared? A correction notice is left at the job site when an inspection fails; the item is cleared by calling for and passing a subsequent re-inspection. 65% · FAQ page
