City of Hermosa Beach

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% · department page
• What does this authority permit itself, and what does it delegate? Both 90% · department page
• Is a permit required for a residential rooftop PV system? Yes 95% · ordinance
• Is there a separate electrical permit, or is it combined? Combined 80% · fee schedule
• Is a HOA or architectural approval required first? No 65% · ordinance
• Is there a historic-district review? No for an ordinary residence; a Certificate of Appropriateness under Chapter 17.53 Historic Resources Preservation IS required if the property is an individually designated 'landmark' (or on the list of resources being considered for designation) — that chapter contains no solar-specific exemption from the Certificate of Appropriateness requirement. 75% · ordinance
• Is a wind or windstorm certification required? No dedicated windstorm-certification requirement found 70% · permit checklist
• Is a Specific Use Permit or Council approval ever required? No — small residential rooftop solar is reviewed at staff (Director) level via a ministerial/administrative Administrative Permit under HBMC 17.46.220(D); Planning Commission/Council involvement only arises on appeal of the Director's decision. 75% · ordinance
• Is there a system-size cap on residential generation? No codified numeric kW cap on residential solar generation; the practical processing gate is the 38.4 kW AC ceiling in the City's own Solar Streamline/Express Checklist (a SolarAPP+/SB 379 §65850.52-style streamlined-review eligibility threshold, not a hard prohibition — larger systems simply route to standard plan review). 85% · permit checklist

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 60% · permit checklist
• Must the contractor be registered with this authority before applying? Yes 90% · department page
• Is a homeowner permitted to self-install and self-permit? Yes 55% · permit checklist

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? Completed Residential Rooftop Solar PV Streamlined Permit Application/Checklist, City Building Permit Application, Plot/Site Plan, and complete construction plans; if an ESS is included, the LA County Fire ESS/PV approval documentation must also be included. 95% · permit checklist
• How many copies, and in what format? Electronic/digital submittal through the Hermosa Beach Online Permitting (Accela Citizen Access) portal — 'upload all documents' — no physical-copy count specified. 80% · department page
• Is a site plan required, and what must it show? Yes, a Site/Plot Plan is required; the city's template captures property/job/applicant information plus a plot-plan drawing area, but does not itemize required plan contents beyond that. 75% · permit checklist
• Is a one-line / three-line diagram required? Yes 90% · permit checklist
• Are string and conductor calculations required? Yes 75% · permit checklist
• Is a structural PE stamp required, and at what threshold? A structural PE/architect stamp is required UNLESS the project qualifies for the prescriptive path in the city's own Solar Streamline checklist (items 43-53: ≤3 stories, not over wood shake/shingle, ≤4 psf system weight, roof framing within the checklist's prescriptive spacing/span tables). Item 42: 'If no [registered design professional stamp], complete questions 43 through 53.' 90% · permit checklist
• Is an electrical PE stamp required, and at what threshold? No mandatory PE stamp for electrical if the installation is designed/certified by a C-10 electrical contractor; the acknowledgment statement requires the electrical plans to be 'stamped and signed by a California Licensed Electrical Engineer OR a C-10 Electrical Contractor' — i.e., a PE stamp is one of two acceptable options, not a mandatory threshold trigger. 85% · permit checklist

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+ (design registration/automated code-compliance check) feeding into the City's Accela Citizen Access ('Hermosa Beach Online Permitting (ACA)') portal for permit issuance; inspections booked via a Veribook online scheduling page. 95% · department page
• Can the whole application be completed online? Yes 85% · department page
• What does a residential solar permit cost? $450 flat for 1-15 kW (residential); +$15 per additional kW above 15 kW. 95% · fee schedule
• How is the fee calculated? Tiered 90% · fee schedule
• Is there a separate plan-check fee? No 80% · 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? 45 days 85% · ordinance
• How long is an issued permit valid before it expires? Work must begin within 12 months of permit issuance and be completed within 4 years; the Building Official may grant up to two 1-year extensions for good cause. 95% · ordinance
• Which utility handles interconnection here? Southern California Edison (SCE) 85% · 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? 2025 CEC (based on the 2023 NEC) 90% · adopting regulation
• Which building code edition is in force? 2025 CBC (Title 24, Part 2), effective 1/1/2026 statewide 90% · adopting regulation
• Which fire code edition is in force? Los Angeles County Title 32 Fire Code, 'as amended and in effect on March 2, 2023' (a date-pinned incorporation of the 2022 CFC), per HBMC 15.20.010 — most recently re-adopted/amended by Ord. #25-1493U, effective 12/9/2025. 90% · adopting regulation
• Are there local amendments to any of the above? Yes 95% · ordinance
• What is the installation judged against? The 2025 CEC/CRC/CBC/CEnC/CMC as locally amended, plus LA County Title 32 Fire Code as amended and effective 3/2/2023 for fire-safety items; the City's own Solar Streamline checklist frames compliance specifically against CRC R324 (PV) and R328 (ESS), and CEC Articles 690/705/706. 90% · permit checklist

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? State-model CRC R324.6 pathways/setbacks apply, with no local amendment found: minimum two 36"-wide pathways from lowest roof edge to ridge on separate roof planes (one on the street/driveway side), and a ridge setback of 18" (if PV occupies ≤33% of roof area) or 36" (if >33%) on both sides of the ridge — reproduced verbatim in the City's own checklist items 20-25 [CRC R324.6.1-.2]. 85% · permit checklist

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 (checklist item 8: PV rapid-shutdown equipment must be listed and labeled), governed by the 2025 CEC (based on the 2023 NEC, which contains §690.12). Confidence is not higher because neither the municipal code nor the City's own checklist cites '§690.12' by number — the checklist (dated Aug 2024) still frames the requirement under the 2022 CEC, a code-cycle lag against the current 12/9/2025 adoption. 75% · permit checklist

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? Generic CEC 110.21 equipment/conductor markings and placards at the service equipment/DC conduits (checklist item 13); where an ESS is included, LA County Fire's own disconnect placards ('F.D. – ELECTRICAL / BLDG DISCONNECT / #X of Y') at exterior panels/enclosures, per the LACoFD Guide the City's SolarApp+ page links directly. 85% · utility/fire agency spec
• Does the authority specify placard wording of its own? No independent city-authored wording for ordinary PV/electrical markings (the checklist simply cites CEC 110.21); LA County Fire DOES specify its own exact placard wording for the disconnect placards it requires on ESS/PV disconnects. 85% · utility/fire agency spec
• Does it specify letter height, colour or material? City's own document specifies material only: markings 'permanently etched on plastic or phenolic resin placards,' with sticker marking permitted on DC conduits/junction boxes — no letter-height or colour given by the City itself. LA County Fire's own spec (for its disconnect placards specifically) is fully dimensioned: minimum 2"x3.5" exterior / 7/16"x3/4" panel-interior, red letters engraved into a yellow background, Arial all-caps, minimum font size 24 (28 bold for 'F.D.' and '#X of Y'), epoxy-mounted. 85% · utility/fire agency spec
• Is a site plan / facility map placard required, and what must it show? For ESS specifically, yes: a permanent plaque or directory 'denoting all electrical power sources on or in the premises and system disconnecting means at each service equipment location' is required [CRC R328.2, CEC 706.21] — functionally the NEC 705.10-style multiple-power-source directory. No separate, distinct facility-map/site-plan placard beyond that is named in the City's own documents for PV-only systems. 80% · permit checklist
• Where must the labels be placed? At/near the service equipment and DC conduits/junction boxes (item 13); ESS disconnect marking 'within sight of the ESS' (item 39); LA County Fire's exterior placards on/immediately adjacent to each panel/enclosure or standalone disconnect that must be operated (LACoFD Guide, Appendix B.7). 85% · permit checklist

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? The City's own local CEC amendment requires the general service disconnect to be 'installed in an exterior location approved by the Building Official' (HBMC 15.08.020, amending CEC §230.70(A)(1)) — a City-side rule, but not stated relative to the utility meter specifically, and not solar-specific. 60% · ordinance
• Must equipment be on a specific approved list? Yes 95% · permit checklist
• Are batteries permitted, and under what conditions? Yes, batteries/ESS are permitted, extensively regulated per CRC R328 as reproduced in the City's own checklist: location restricted to detached garage/accessory structure, attached garage (separated per CRC R302.6), exterior wall (≥36" from doors/windows), or an enclosed, fire-rated interior utility space — never a sleeping room or space opening into one; size-capped by location (20 kWh per single unit, 38.4 kWh aggregate for more than one unit per location); fire detection, vehicle-impact protection (bollards/wheel barriers, dimensioned), and a marked, accessible disconnect are all required. An ESS must also be previously reviewed and approved by LA County Fire before the City permit is issued. 90% · permit checklist
• Is there a separate ESS permit or inspection? Not a separate CITY permit (the ESS is folded into the same solar permit application), but YES a separate, prior approval is required: LA County Fire must review and approve the ESS design before the City permit application, and that LACoFD approval package must be uploaded with the City submittal. 85% · department page
• Is a ground mount treated as a structure? Not codified specifically for solar; no dedicated ground-mount PV/ESS provision was found anywhere in the zoning title (control-checked full-text search for 'ground mount', 'accessory structure' + 'solar' returns no PV-specific hit), so a ground-mounted array would default to the City's general accessory-structure standards rather than a purpose-built solar rule. 55% · ordinance
• Is there a local rule on service upgrades or busbar sizing? Yes on service upgrades: HBMC 15.08.030 requires electrical service to be placed UNDERGROUND whenever 'any panel upgrade, including increases in amperage or relocation of the main service panel' occurs (among other triggers), subject to a documented Building-Official exception (15.08.040) — a locally significant rule that can reach a main-panel upgrade done alongside PV. No local busbar-minimum or attic-ambient-derating amendment (Palm Springs-style) was found; the only busbar figure in the City's documents (225A minimum, ESS panelboards) is the NATIONAL CEC 706.10 rule, cited in the Solar Streamline checklist item 40 — not a local amendment. 90% · ordinance
• Is a specific mounting system or attachment spacing required? Yes — detailed prescriptive standards in the City's own Solar Streamline checklist: measured rafter/truss spacing and span against manufacturer/prescriptive tables (Tables 1 and 2), anchor horizontal spacing checked against Table 1, and lag-screw/fastener specs (5/16" diameter, 2.5" embedment, or per manufacturer guidelines) for the prescriptive structural path. 85% · permit checklist

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% · 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 85% · department page
• If delegated, to whom? N/A for the general PV inspection (self-performed by City Building & Safety); for Energy Storage Systems specifically, PLAN REVIEW/APPROVAL is delegated to the Los Angeles County Fire Department before the City permit is even issued. 80% · 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? 1) Register/submit for automated code-compliance review via SolarAPP+ (pay SolarAPP+ processing fee); 2) if an ESS is included, submit for and obtain LA County Fire's ESS/PV approval first; 3) apply for the City SolarPV permit via the Accela (ACA) portal, uploading SolarAPP+ approved plans (+ LACoFD approval if applicable), and pay the City permit fee; 4) schedule and pass the City building/electrical inspection, having the approved plans, LACoFD documents (if applicable) and inspection checklist on site; 5) return the signed permit card to the City. 90% · department page
• Is a rough-in or mid-roof inspection required? Not indicated — only a single 'Schedule Inspection' step is described in the City's own process page, with no separate rough-in/mid-roof stage named. 60% · 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 90% · permit checklist
• What must be on site at inspection? Manufacturer's installation instructions for all installed equipment (checklist item 6); the SolarAPP+-approved plans and inspection checklist; and, if an ESS is included, the LA County Fire approval documentation (checklist item 27; SolarApp+ page step 4). 90% · permit checklist
• Does the inspector verify labels and listings? Yes 80% · permit checklist

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? A signed permit card, returned by the installer to the City ('Return the Signed permit card to the City'). 70% · department page
• Is there a re-inspection fee? No dedicated re-inspection fee line found; the Master Fee Schedule's general Schedule C (Electrical) catch-all applies to unenumerated inspections: '$75 per hour (minimum charge - four hours)' for 'inspections for which no fee is specifically indicated.' 55% · fee schedule
