City of Rosemead

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 — City of Rosemead (Building and Safety Division, Community Development Dept.) is the AHJ for building/electrical permitting of residential rooftop PV; Los Angeles County Fire Department (LACoFD) is the fire AHJ and retains inspection authority over ESS >3kWh, qualifying BIPV, and PV disconnect/rapid-shutdown placarding. 92% · ordinance
• What does this authority permit itself, and what does it delegate? Both 88% · ordinance
• Is a permit required for a residential rooftop PV system? Yes 96% · ordinance
• Is there a separate electrical permit, or is it combined? Combined 68% · department page
• Is a HOA or architectural approval required first? No — HOA/architectural approval cannot be a precondition for permit issuance 62% · ordinance
• Is a Specific Use Permit or Council approval ever required? Yes, in limited cases 88% · ordinance
• Is there a system-size cap on residential generation? 10 kW AC (or 30 kW thermal) for the local expedited 'Small Residential Rooftop Solar Energy System' definition 85% · ordinance

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 50% · ordinance
• Must the contractor be registered with this authority before applying? No separate city contractor registration found; SolarAPP+ path requires the contractor be added to the SolarAPP+ program eligibility list before submission 75% · department page
• Is a homeowner permitted to self-install and self-permit? Not explicitly addressed for solar specifically 45% · department page

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+-approved plan set + SolarAPP+ compliance checklist, emailed together with the City's Permit/Plan-Check Worksheet to Building & Safety (buildinginfo@rosemeadca.gov) 80% · department page
• How many copies, and in what format? Electronic (email/PDF) submittal; no copy count specified 55% · department page
• Is a site plan required, and what must it show? Not separately specified for solar; SolarAPP+'s own standard checklist requires a roof/site plan showing panel layout, access pathways, and setbacks as part of its nationwide code-compliance check 50% · department page
• Is a one-line / three-line diagram required? Yes (implicit via SolarAPP+'s and the National Electrical Code's standard compliance package) 50% · inference
• Are string and conductor calculations required? Yes (implicit via SolarAPP+/NEC compliance requirements) 45% · inference

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? SolarAPP+ (gosolarapp.org) for eligible small residential rooftop PV; non-eligible projects submit by email to the Building & Safety Division (no Accela/CitizenServe-style general permit portal identified) 85% · portal landing page
• Can the whole application be completed online? Partially — SolarAPP+ itself is a fully online code-compliance/permit-issuance tool, but the City still requires the SolarAPP+ output and its own paper/PDF Permit Worksheet to be emailed in and manually processed by Building & Safety before the permit is returned 75% · department page
• How is the fee calculated? Valuation 78% · ordinance
• Is there a separate plan-check fee? Yes (inferred) 60% · ordinance

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? Same day for over-the-counter applications; 1–3 business days for electronic applications 95% · ordinance
• How long is an issued permit valid before it expires? 365 days (permit becomes void if work is not commenced within one year of issuance) 85% · ordinance
• Which utility handles interconnection here? Southern California Edison (SCE) 78% · department 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 92% · ordinance
• Which building code edition is in force? 2025 California Building Code (Title 24 Part 2), as amended/adopted via the 2026 Los Angeles County Building Code (Title 26) 93% · ordinance
• Which fire code edition is in force? 2023 Los Angeles County Fire Code (LACFC, LACC Title 32), itself a locally-amended version of the 2022 California Fire Code 72% · ordinance
• Are there local amendments to any of the above? Yes 90% · ordinance
• What is the installation judged against? The 2025 CEC/2023 NEC as locally amended by the 2026 LA County Electrical Code (Title 27); structurally, the 2025 CBC/2026 LA County Building Code (Title 26); and for disconnects/placarding/ESS, the 2023 LACFC (Title 32), §§105.3.6, 509–509.3, 1201.2, 1207.11 82% · ordinance

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 Rosemead 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 is required per NEC 690.12, incorporated via the 2023 NEC/2025 CEC in force 82% · ordinance

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? LACoFD 'F.D. – ELECTRICAL BLDG DISCONNECT' exterior placard(s) at each disconnect panel/enclosure, plus matching panel-interior placards identifying specific switches/breakers, per the LACoFD Electrical Power Source Disconnect Placarding System 88% · fire code / AHJ guide
• Does the authority specify placard wording of its own? Yes 90% · fire code / AHJ guide
• Does it specify letter height, colour or material? Yes — Exterior placards: min. 2"x3.5" weather-resistant plastic, red letters engraved on a yellow background, solid all-capitals Arial font min. 24pt (28pt bold for 'F.D.' and '#X of Y'); Panel-interior placards: min. 7/16"x3/4" same colors, all-caps bold Arial min. 24pt; attached with permanent, weather/material-compatible epoxy 92% · fire code / AHJ guide
• Is a site plan / facility map placard required, and what must it show? Not a separate 'facility map' placard found; NEC 705.10 (general requirement for a directory/plan-view identification of all power sources at service equipment, as incorporated by the 2025 CEC) is the applicable code driver, implemented locally through the LACoFD disconnect-placard numbering scheme (each disconnect labeled '#X of Y') 55% · inference
• Where must the labels be placed? Exterior placards go on/immediately adjacent to each panel/enclosure or standalone disconnect switch that must be operated; panel-interior placards go inside the panel to identify specific switches/breakers when more than one within the same enclosure must be operated; exact placement is determined by a C-10 electrician and is subject to fire-code-official approval 88% · fire code / AHJ guide

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? Within 6 feet of the main service panel, on the same wall plane, not separated by walls/gates/fences/vegetation or architectural features — a Fire Code rule, not a utility rule 82% · fire code / AHJ guide
• Must equipment be on a specific approved list? Yes (inferred) 55% · inference
• Are batteries permitted, and under what conditions? Yes, with conditions — max 20 kWh per individual ESS unit, 80 kWh aggregate per site (R-3/R-4), UL 9540 (unit) / UL 1741 (inverter) listing, minimum spacing (3-10 ft depending on exposure), impact protection where subject to vehicular impact, and alarm/detection where installed in an attached garage 88% · fire code / AHJ checklist
• Is there a separate ESS permit or inspection? 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 (online web form) or Email 90% · department page
• How much notice is required? Effectively next-business-day: requests must be submitted by 3:30 PM to be considered for a next-day inspection, subject to availability 88% · department page
• Are same-day or AM/PM windows offered? Yes — explicit A.M./P.M. preference is collected on the inspection-request form 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? Delegated / Split 72% · fire code / AHJ checklist
• If delegated, to whom? Los Angeles County Fire Department (LACoFD), Fire Prevention Division — regional inspection office (specific office assigned to Rosemead not confirmed; Rosemead is not listed by name on LACoFD's own regional-office phone/email list, whose nearest listed offices are Commerce and East Los Angeles in the 'Central Region') 58% · department directory

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? Not fully documented; SolarAPP+ process implies a single final inspection step after permit issuance for straightforward residential PV 50% · department page

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 for LACoFD's ESS/PV/Disconnect-placarding inspection checklist (published, extracted in this run); not found for a City of Rosemead general-building PV-specific inspection checklist 70% · fire code / AHJ checklist
• What must be on site at inspection? Digital proof of the construction permit (e.g., the SolarAPP+ approval) and, where LACoFD inspection applies, cut/spec sheets for ESS components on request and LACoFD invoicing information; the City's own rule implies the inspection record card and approved plans must be posted/available on site 72% · fire code / AHJ checklist
• Does the inspector verify labels and listings? Yes (inferred from standard final-inspection practice under the adopted Electrical/Fire codes) 55% · inference

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 signed/closed inspection card); a Certificate of Occupancy is a separate, optional document issued 'upon written request by the permit holder' and is oriented toward new construction/occupancy changes, not typically requested for a PV retrofit 55% · ordinance
• Is there a re-inspection fee? $98 (LACoFD 'additional inspections after initial inspection and one reinspection', Table QQ104.4(6)); City of Rosemead's own re-inspection fee amount is not published — the ordinance allows one but sets no dollar figure 72% · fee schedule
• How are corrections issued and cleared? Not fully documented; RMC 15.02.040(C) lists the conditions that trigger a re-inspection fee (incomplete work, uncorrected items, inadequate site access, missing inspection card, unavailable approved plans, or deviation from approved plans) but does not describe a formal correction-notice/clearance process 60% · ordinance
