City of Monrovia

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 (building and electrical are self-performed by the City's own Building & Safety Division); fire plan review/inspection is separately self-performed by Monrovia's own Fire Department (not delegated to LA County Fire) 88% · department page
• Is a permit required for a residential rooftop PV system? Yes 85% · department page
• Is there a separate electrical permit, or is it combined? Combined 65% · permit schedule
• Is there a historic-district review? Yes -- but scope for rooftop PV specifically not confirmed 65% · department page
• Is a wind or windstorm certification required? No 50% · department page
• Is a Specific Use Permit or Council approval ever required? Not specifically for rooftop residential PV. A separate, real 'Hillside Development Permit' authority sits with the Planning Commission for hillside-sited projects generally (per a Planning Commission meeting description), and the Zoning Ordinance (MMC Title 17) is administered with Development Review Committee oversight for other project types, but no document found ties a CUP/SUP/Council-approval trigger specifically to residential rooftop PV. 55% · 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? No 65% · department page
• Is a homeowner permitted to self-install and self-permit? Yes 60% · 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? For SolarAPP+-eligible projects: contractor registers, submits system design, and pays fees through SolarAPP+ itself (design + fee payment IS the submittal); no separate City submittal is filed. For non-eligible projects (ground-mount, new construction, non-residential, and anything failing the Eligibility Checklist), the standard package is the City's general 'Plan Review Application' and 'Permit Application' forms plus staff plan review. 70% · 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? SolarAPP+ (solarapp.nrel.gov) for eligible residential rooftop PV; no separate general online permitting e-portal name was found for standard (non-SolarAPP+) building permits 78% · portal landing page
• Can the whole application be completed online? Yes for SolarAPP+-eligible projects (register, submit design, pay fees, and receive approval documents entirely online); not established for standard/non-eligible projects, which appear to require in-person plan review 70% · portal

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.

• Which utility handles interconnection here? Southern California Edison (SCE) 60% · 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? 2017 NEC (as the electrical component of the '2019 California ... Codes' cycle the City's own page currently cites) -- flagged as likely stale 45% · department page
• Which building code edition is in force? 2019 California Building Code (per the City's own current page) -- flagged as likely stale relative to the statewide 2022 and 2025 cycles 45% · department page
• What is the installation judged against? The 2019 California Building, Residential, Electrical, Plumbing, Mechanical, CalGreen, and Monrovia Municipal Codes, per the City's own current permit-requirements page (see staleness caveat at Q29/Q30) 45% · department page

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.

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.

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.

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.

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? Phone 90% · department page
• How much notice is required? Effectively next-business-day: requests must be made by 3:00 p.m. the business day before the requested inspection date 85% · department page
• Are same-day or AM/PM windows offered? Yes -- AM (8:00 a.m.-12:00 noon) and PM (1:30 p.m.-4:30 p.m.) windows, Monday-Thursday; Building & Safety counter has limited Friday hours (7:00 a.m.-5:30 p.m.) 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 88% · department page
• If delegated, to whom? N/A -- not delegated; the City's own Building Inspector performs the final inspection 85% · 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.

• Which inspections are required, and in what order? For SolarAPP+ projects: a single final inspection is scheduled once installation is complete, following SolarAPP+ approval and permit creation (no rough-in/mid-roof stage is described). For standard-review projects, the general Building Division sequence is plan review at the counter, then inspection(s), but stages are not itemized specifically for PV. 55% · 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 75% · department page
• What must be on site at inspection? The approved SolarAPP+ (or standard-review) plan set and the issued permit must be available at the project site for the inspector 88% · department page

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.

• How are corrections issued and cleared? Corrections/revisions are resubmitted through SolarAPP+ itself; once processed, the applicant receives a downloadable revised SolarAPP+ Approval Document, which must also be kept on site 78% · department page
