City of Grand Terrace

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 — Building and Electrical self-performed in-house by the City's own Building & Safety Division. Fire code enforcement is delegated by cross-reference to San Bernardino County Fire Protection District's amended Fire Code (SBCoFD Ordinance No. 23-01). 85% · adopted budget + municipal code
• Is a permit required for a residential rooftop PV system? Yes 95% · municipal code
• Is there a separate electrical permit, or is it combined? Combined 72% · department page
• Is a HOA or architectural approval required first? No (for the AHJ's own process) — but see note 65% · municipal code
• Is there a historic-district review? No 68% · municipal code (chapter-list absence)
• Is a wind or windstorm certification required? No 65% · municipal code (control-checked absence)
• Is a Specific Use Permit or Council approval ever required? Yes, conditionally — an Administrative Conditional Use Permit is required only if the Building Official finds, based on substantial evidence, that the system 'could have a specific, adverse impact upon the public health and safety'; that decision is appealable to the Planning Commission. 90% · municipal code
• Is there a system-size cap on residential generation? 10 kW AC nameplate / 30 kW thermal (statutory AB 2188 'small residential rooftop solar energy system' definition, codified locally) for expedited-review eligibility. Separately, the city's own fee table uses a different, uncoordinated 15 kW breakpoint for per-kW pricing purposes. 90% · 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 65% · department page (FAQ)
• Is a homeowner permitted to self-install and self-permit? Yes 70% · department page (FAQ)

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? Two copies of plans (legacy over-the-counter path) 60% · department page

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? Symbium 90% · department page + adopted budget
• Can the whole application be completed online? Yes 85% · department page
• What does a residential solar permit cost? $75 flat (as currently charged per the FY2023 Cost of Services Study's Building Trade Times table), covering a residential system up to the table's 15 kW breakpoint 62% · fee schedule (Master Fee Resolution 2023-30, Appendix C)
• How is the fee calculated? Flat 62% · fee schedule (Master Fee Resolution 2023-30, Appendix C)
• Is there a separate plan-check fee? No — the $75 residential solar figure in the current fee table appears to be a single combined fee rather than separate plan-check and permit lines (unlike the general valuation-based Building Permit/Building Plan Check tables in the same document, which ARE split). 55% · fee schedule (Master Fee Resolution 2023-30)

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? 3 business days (over-the-counter) / 5 business days (electronically filed) 92% · municipal code
• How long is an issued permit valid before it expires? 6 months from issuance or the last approved inspection (general permit-validity rule; no solar-specific validity period found) 72% · department page (FAQ)
• Which utility handles interconnection here? Southern California Edison (SCE) 95% · city webpage

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 (adopted as part of the 2025 California Electrical Code) 95% · municipal code (adopting ordinance)
• Which building code edition is in force? 2025 California Building Code (based on the 2024 International Building Code) 95% · municipal code (adopting ordinance)
• Which fire code edition is in force? 2025 California Fire Code, with local amendments as provided in San Bernardino County Fire Protection District Ordinance No. 23-01 90% · municipal code (adopting ordinance)
• Are there local amendments to any of the above? Yes 90% · municipal code
• What is the installation judged against? The adopted 2025 CBC/CRC/CEC/CFC (the latter with SBCoFD amendments) plus solar-specific standards under §15.24.040: California Electrical Code, IEEE, UL/accredited testing laboratories, and CPUC safety/reliability rules where applicable. 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 Grand Terrace 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? Rapid shutdown is required by default under the adopted 2023 NEC (via the 2025 CEC); the city's own documents do not separately cite NEC §690.12 or state a rapid-shutdown requirement in their own words. 65% · inference from adopted NEC edition

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 70% · municipal code (control-checked absence)
• Does it specify letter height, colour or material? No 70% · municipal code (control-checked 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.

• Are batteries permitted, and under what conditions? Yes, batteries/ESS are permitted; conditions are set by the fire code the city adopts by cross-reference (SBCoFD Ordinance No. 23-01), which — in a neighboring SBCoFD-served city — carries an operational-permit requirement for battery/ESS with an explicit R-3 (single-family residential) exemption. Grand Terrace's own copy of that SBCoFD ordinance text was not independently retrieved, so this is reported as a comparable-authority inference, not a directly-read Grand Terrace clause. 60% · municipal code (cross-reference) + comparable-authority inference
• Is there a separate ESS permit or inspection? No separate fee line found for a stand-alone ESS permit/inspection. 72% · fee schedule (control-checked absence, two documents)
• Is a ground mount treated as a structure? Yes, by inference 58% · municipal code (inference from general definition)
• Is there a local rule on service upgrades or busbar sizing? No local rule found — the Electrical Code chapter (§15.12) is a single straight-adoption section with no service-upgrade or busbar-sizing amendment. 80% · municipal code (control-checked absence)

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? Email 82% · 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 95% · municipal code
• If delegated, to whom? Not delegated for the building/electrical inspection itself (performed by the City's own Building Department per §15.24.060(G)); the Fire Code's SBCoFD cross-reference (§15.18.010) and the chapter's own 'consolidated inspections' language (§15.24.060(H)) leave open that a fire-district representative may jointly participate, but the ordinance does not name SBCoFD explicitly in that clause the way a neighboring city's ordinance does. 55% · municipal code (inference on the fire-participation half)

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? A single, consolidated inspection (no separate rough-in/mid-roof/final sequence) for systems eligible for expedited review. 90% · municipal code
• Is a rough-in or mid-roof inspection required? No 78% · municipal code

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 published inspection checklist was found for Grand Terrace specifically. 62% · department page (control-checked absence)

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 (a completed 'permit and job card' / final sign-off; no distinct 'Green Tag' or 'CO' terminology found for residential solar specifically) 55% · inference from department page
• Who notifies the utility for PTO? Installer (inferred; not stated by the city) 50% · inference (general NEM practice)
• Is there a re-inspection fee? No separate re-inspection dollar figure; billed at the general hourly rate, $181.00/hour, per the current fee schedule ('Re-Inspections / Other Services Not Specified — Hourly Rate', cross-referenced against the same document's 'Other Electrical Inspections (per hour) $181.00' and 'After-Hours Inspection (4-hour minimum) $723.00' = 4 × $180.75). 65% · fee schedule
• How are corrections issued and cleared? For an incomplete APPLICATION (pre-permit stage): a written correction notice detailing all deficiencies is sent to the applicant for resubmission. How corrections found at the INSPECTION stage are issued/cleared was not documented anywhere retrieved. 60% · municipal code (partial answer)
