City of Rolling Hills

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 92% · adopting ordinance (Municode)
• What does this authority permit itself, and what does it delegate? Both 85% · department staff directory
• Is a permit required for a residential rooftop PV system? Yes 95% · municipal code + county permitting bulletin hosted on city site
• Is there a separate electrical permit, or is it combined? Combined 88% · county permitting bulletin (linked from city's own solar page)
• Is a HOA or architectural approval required first? Yes -- mandatory Rolling Hills Community Association (RHCA) Architectural Committee approval, required BEFORE City/County permits, for solar installations. 95% · city planning application form (signed acknowledgment)
• Is there a historic-district review? No 75% · municipal code (absence, full TOC read by name)
• Is a wind or windstorm certification required? No 70% · municipal code + county structural criteria (absence)
• Is a Specific Use Permit or Council approval ever required? Generally no for an eligible small residential rooftop PV system standing alone: RHMC 17.16.200(K) limits City review of a solar-panel application to code-compliance criteria, bypassing the discretionary Site Plan Review (Ch. 17.46) and Conditional Use Permit (Ch. 17.42) tracks that apply to other accessory structures/uses. A CUP or Site Plan Review could still be triggered if the PV installation is bundled with other work that independently crosses an SPR threshold (e.g., grading, or a new/expanded structure over 999 sq ft per RHMC 17.46.020), but not by the solar system itself. 75% · municipal code
• Is there a system-size cap on residential generation? No hard prohibition-style cap in the municipal code; the operative size threshold is the County's expedited/ministerial review track: County BCM 6807's expedited process 'provides for expedited permit processing of small residential rooftop solar energy systems on one- or two-family dwelling that involves either a photovoltaic system that is no larger than 10 kilowatts alternating current or a solar thermal system that is no larger than 30 kilowatts thermal.' Systems above that size are not barred, but fall out of the expedited/OTC path into standard (non-expedited) County plan review. 78% · county permitting bulletin

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% · county permitting bulletin (linked from city's own solar page)
• Must the contractor be registered with this authority before applying? No 68% · municipal code (absence, TOC read in full)
• Is a homeowner permitted to self-install and self-permit? Yes 85% · county permitting bulletin (linked from city's own solar 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? Per County BCM 6807 Attachment A: (a) completed permit application form; (b) demonstrated compliance with the Eligibility Checklist for Expedited Solar PV Permitting (Attachment B); (c) a completed Standard Electrical Plan (for systems <=10kW) or engineered electrical plans; (d) a roof plan showing panel layout, roof access point, code-compliant fire access pathways, PV fire classification, and label locations; (e) completed Structural Criteria (Attachment E) with supporting worksheets/calculator results, or project-specific engineer-stamped calculations if any criterion fails; (f) a completed Form A/B/C affidavit. Separately and BEFORE County submittal: the City's own 'Over the Counter Approval' Planning application, and the private Rolling Hills Community Association's (RHCA) 'Application for Plan Check' plus its own Plan Submittal Checklist (site plan with easement lines, collector square footage, rack height; roof plan with vent locations and a cross-section; a sample/photo/brochure of the proposed system and color). 85% · county permitting bulletin + RHCA architectural regulations
• How many copies, and in what format? Electronic submittal is the documented route at both layers: the City's Planning portal (iWorQ) is an upload-based online application system, and County BCM 6807 states permit applications 'can be submitted electronically through' the County's Building & Safety Online Plan Check (BSOP) portal. No specific paper-copy count is published for either layer. RHCA's own process (Application for Plan Check) appears to be a paper/PDF submittal with no published copy count either. 55% · permit portal + county bulletin
• Is a site plan required, and what must it show? Yes. County BCM 6807 requires a roof plan (Attachment A(d)) showing roof layout, PV panel locations, roof access point, code-compliant access pathways, PV fire classification, and label locations. RHCA separately requires a site plan showing property/easement lines, collector square footage, and rack height as part of its own Architectural Committee submittal. 88% · county permitting bulletin + RHCA architectural regulations
• Is a one-line / three-line diagram required? Yes 82% · county permitting bulletin (standard electrical plan worksheet)
• Are string and conductor calculations required? For systems eligible for the expedited/standard-plan path, conductor and disconnect ratings are captured on the Standard Electrical Plan worksheet itself (inverter/OCPD amperage and voltage entries feeding the pre-approved single-line diagrams) rather than as a freestanding string/conductor-calculation submittal; for systems that fail the Eligibility Checklist or Structural Criteria, project-specific engineer-stamped calculations (structural) and full engineered electrical plans (conductor/OCPD sizing) are required. 68% · county permitting bulletin (inference from worksheet structure)
• Is a structural PE stamp required, and at what threshold? Yes, but only conditionally: County BCM 6807 Attachment E (Structural Criteria for flush-mounted roof PV arrays) is a pass/fail checklist (roof condition, elevation <2,000 ft, not within 200 yards of the ocean/bay, array weight <=4 psf, coverage <=50% of roof area, anchor spacing within Table 1, lag-screw/embedment per spec or an LA-County-approved anchor). Per the Summary clause: 'All items above are checked YES. No additional calculations are required' OR 'One or more items are checked NO. Attach project-specific drawings and calculations stamped and signed by a California-licensed Civil or Structural Engineer.' So a PE/SE stamp is triggered only when the array fails any item on this checklist (e.g., heavier module/rack systems, >50% roof coverage, non-conforming anchors, or a non-flush/ground-mounted array, which falls outside this document's scope entirely). 78% · county permitting bulletin (structural criteria attachment, dated)

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? Two portals, one at each layer: the City's Planning Department uses an iWorQ citizen portal (rollinghillspermits.portal.iworq.net) for Discretionary Review, Administrative Approval, and Over-the-Counter applications. Building/electrical permits are administered by the Los Angeles County Dept. of Public Works, Building & Safety Division through the County's own Building & Safety Online Plan Check (BSOP) portal at dpw.lacounty.gov/bsd/bsop, per County BCM 6807. 85% · permit portal landing page
• Can the whole application be completed online? Yes 68% · permit portal landing page + county bulletin
• What does a residential solar permit cost? Best documented figure: County Building Code Manual (BCM) 6807 states the combined solar PV building+electrical permit fee for small residential rooftop systems 'shall not exceed $500 unless modified by or in accordance with Government Code Section 66015 or other applicable law.' Separately (and additively, as a precondition), the private Rolling Hills Community Association charges its own $250 'Application Fee for Architectural review' plus a $200 line-item 'Solar Panels' building-permit fee under its own (non-AHJ) Schedule of Fees, effective per the PDF's Feb 2025 creation date. 60% · county permitting bulletin (dated) + current city fee schedule (absence) + RHCA fee schedule
• How is the fee calculated? Flat 55% · county permitting bulletin (dated) + RHCA fee schedule
• Is there a separate plan-check fee? No 62% · current city fee schedule (absence, read in full) + county bulletin

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 / over-the-counter for eligible expedited submittals: County BCM 6807's structural-criteria attachment is explicitly described as 'a one-page list of structural criteria for over-the-counter or online approval,' and the whole BCM 6807 process is titled 'Expedited Permitting.' No day-count turnaround is published for systems that do not qualify for the expedited/standard-plan path and go through ordinary County plan check. 65% · county permitting bulletin
• How long is an issued permit valid before it expires? The clearest documented figure is the private Rolling Hills Community Association's own building permit validity: 'Permits are active for one year from issue date. Permit extensions are available by written request.' The City/County building-permit expiration period under the adopted 2025 California Building Code Section 105.5 (as adopted via LA County Title 26, RHMC 15.04.010) was not independently verified this run -- the City's only local amendment to Building Code Section 105 (RHMC 15.04.030) adds a review-hearing subsection and does not touch the expiration clause, so the County's own unmodified CBC 105.5 language would govern, but its exact text was not located separately from the base code adoption. 55% · RHCA fee schedule (private HOA permit) + inference for county permit

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% · adopting ordinance (Municode)
• Which building code edition is in force? 2025 California Building Code 92% · adopting ordinance (Municode)
• Which fire code edition is in force? 2025 California Fire Code 88% · adopting ordinance (Municode)
• Are there local amendments to any of the above? Yes 82% · municipal code (local amendment sections)
• What is the installation judged against? The 2025 California Building, Residential, Electrical, Green Building Standards, and Fire Codes, each adopted via Los Angeles County's Titles 26/30/27/31/Fire Code provisions 'as amended and in effect January 1, 2026' and incorporated into RHMC Title 15 by Ordinance No. 389-U (Dec. 9, 2025); solar-specific installation criteria for the expedited path additionally draw on LA County DPW's Building Code Manual (BCM) 6807 Article 1 standard plans/structural criteria and LACoFD's Guide for ESS, PV, and Disconnects (Rev. 3, 2023-09-01), both of which the City links directly or which apply county-wide to LACoFD-served cities. 85% · municipal code + county bulletins

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? No Rolling-Hills-specific numeric ridge-setback amendment found; RHMC's Fire Code chapter (15.20) has its local-amendments section (15.20.040) marked 'Reserved' (no local FD amendments currently adopted). County BCM 6807's roof-plan submittal requirement instead points applicants to the State Fire Marshal's Solar PV Installation Guide for 'code-compliant access pathways' -- i.e. the statewide/CFC standard pathway requirements govern, not a Rolling Hills-specific ridge setback. 76% · municipal code + county bulletin

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. LACoFD's current (effective 2023-09-01) Expedited PV/ESS Permitting Inspection Checklist lists 'Rapid-Shutdown attenuation devices, and associated placarding' as an item requiring LACoFD inspection, and its Disconnect Placarding system explicitly requires that 'PV Rapid Shutdown function activation (where present) is encompassed' in the placarding. This sits on top of the base NEC 690.12 rapid-shutdown mandate carried by the City's now-adopted 2025 California Electrical Code (2023 NEC). 80% · county fire authority current inspection 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? At minimum: (1) LACoFD's own 'F.D. -- ELECTRICAL BLDG DISCONNECT' / '# X of Y' exterior placard at each required electrical disconnect (plus a matching panel-interior placard identifying specific switches/breakers within a shared panel); and (2) the standard NEC/CRC-mandated PV warning labels (inverter-output OCPD warning, DC-ungrounded-conductor warning, PV-power-source warning at junction/combiner boxes and along conduit every 10 ft, PV system AC/DC disconnect rating labels, ground-fault warning, and a permanent directory/plaque of all electric power sources on the premises). 85% · county fire authority current placarding appendix
• Does the authority specify placard wording of its own? Yes 85% · county fire authority current placarding appendix
• Does it specify letter height, colour or material? Yes -- LACoFD Appendix B specifies: red letters engraved into a yellow background; exterior placards minimum 2in x 3.5in weather-resistant plastic, Arial all-caps, minimum 24pt (28pt bold for 'F.D.' and '# X of Y'); panel-interior placards minimum 7/16in x 3/4in weather-resistant plastic, Arial all-caps bold, minimum 24pt; attached with permanent epoxy. Separately, County BCM 6807's older NEC-label guidance recommends 'a phenolic plaque with contrasting colors' and '20 point (3/8in)' as a practical minimum, citing ANSI Z535.4. 88% · county fire authority current placarding appendix
• Is a site plan / facility map placard required, and what must it show? Yes -- a directory-style placard is required: County BCM 6807's inspection checklist lists 'Permanent plaque or directory, denoting all electric power sources on or in the premises' among the signs verified at final inspection (the NEC 705.10 facility-directory function). LACoFD's own Disconnect Placarding system separately requires accounting for 'all power sources capable of supplying electricity to a structure's electrical circuit(s) (e.g., utility, generator, PV, ESS, wind, fuel-cell, vehicle-to-grid inputs)' at the disconnect location(s). 78% · county fire authority current placarding appendix + county bulletin
• Where must the labels be placed? Disconnect placards: LACoFD requires them 'on the exterior, within 6 feet of the main service panel, on the same wall plane,' not separated from one another by walls/gates/fences/vegetation/architectural features, and kept readily accessible (not obstructed by stored materials). NEC/CRC labels (junction/combiner box, conduit, disconnects) are placed per County BCM 6807 at the specific components shown in its markings diagram (inverter output OCPD, PV/AC/DC disconnects, junction/combiner boxes, and every 10 ft of conduit run). 85% · county fire authority current inspection 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? Per LACoFD's current fire-code-based rule (which functions as the operative AC-disconnect placement rule here in the absence of a located SCE-specific rule): all electrical disconnection means and rapid-shutdown activation devices for every power source serving the structure must be located on the exterior, within 6 feet of the main service panel, on the same wall plane, unseparated by walls/gates/fences/vegetation/architectural features (2023 LACFC Section 509.3). 70% · county fire authority current inspection checklist
• Must equipment be on a specific approved list? Yes 82% · county fire authority current inspection checklist + county bulletin
• Are batteries permitted, and under what conditions? Yes, batteries/ESS are permitted, under LACoFD's current (2023-09-01) requirements: UL 9540 listing (unit or components) and UL 1741-listed inverter; individual unit rating capped at 20 kWh; aggregate capped at 80 kWh per site and per location category (inside attached garage / detached garage / outdoors on exterior wall / outdoors on the ground); 3 ft spacing between individual units; where outdoors, 3 ft minimum from doors/windows/openings/HVAC inlets, 5 ft from lot lines/public ways/other buildings/combustibles, 10 ft from vegetation; impact protection (pipe- or retrofit-bollard type) where subject to vehicular impact; heat-detection/notification for attached-garage installations; and ESS is prohibited inside dwelling units, sleeping units, closets, bathrooms, basements, or non-garage accessory structures absent an approved alternative means and methods request. ESS >3 kWh requires LACoFD inspection. 80% · county fire authority current requirement guide
• Is there a separate ESS permit or inspection? Yes 78% · county fire authority current inspection checklist
• Is a ground mount treated as a structure? Likely yes for anything beyond a small ground rack: County BCM 6807's Structural Criteria (Attachment E) -- the basis for the expedited/over-the-counter review path -- is explicitly scoped to 'flush-mounted solar arrays installed on the roofs of wood-framed one- and two-family dwellings' only. A ground-mounted array falls outside that scope and, by omission, would need to go through the County's standard (non-expedited) plan review as its own structure, with full engineered foundation/structural plans, rather than the roof-array checklist. 62% · county permitting bulletin (inference from stated scope)
• Is there a local rule on service upgrades or busbar sizing? No Rolling-Hills-specific local rule found. RHMC 15.16 (Electrical Code chapter) contains only four sections -- adoption, definitions, fees, and violations/penalties -- with no busbar-sizing or service-upgrade amendment. The 120%-busbar-rating rule referenced in County BCM 6807's inspection checklist ('Sum of the main OCPD and the inverter OCPD is rated for not more than 120% of the bus bar rating') is the standard state NEC 705.12(B) rule, not a Rolling Hills-specific local amendment. 70% · municipal code (absence, chapter read in full)
• Is a specific mounting system or attachment spacing required? Yes -- for the expedited/flush-mount path, County BCM 6807 Attachment E specifies: modules parallel to and 2-10 inches above the roof surface; not overhanging roof edges; array weight <=4 psf (PV) / <=5 psf (thermal); coverage <=50% of total roof area; anchor horizontal spacing per a roof-slope/rafter-spacing table (Table 1, e.g. 2'-0' o.c. at 24' rafter spacing on a 7:12-12:12 slope); and anchor fasteners of 5/16' diameter lag screws with 2.5' rafter embedment (or an LA County-approved equivalent anchor). 82% · county permitting bulletin (structural criteria attachment, dated)

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 80% · county permitting bulletin
• How much notice is required? Approximately 1 business day 82% · county permitting bulletin
• Are same-day or AM/PM windows offered? No AM/PM window or same-day option is published; only a 'next business day' (or, if unavailable, within-five-days) scheduling commitment appears in the documents reviewed. 60% · county permitting bulletin (absence)

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 88% · department staff directory
• If delegated, to whom? Los Angeles County Department of Public Works, Building & Safety Division (contract services; Lomita district office, 24320 Narbonne Ave., Lomita CA) performs the combination building/electrical/plumbing inspection. The Los Angeles County Fire Department, Fire Prevention Division performs the separate ESS/PV electrical-disconnect-placarding inspection -- Station 56 (12 Crest Rd. West, Rolling Hills) is the suppression unit serving the City per RH's own Fire Department page, and the regional Fire Prevention inspection office serving the geographically adjacent, also-LACoFD-served city of Rolling Hills Estates is named as 'Carson' on that city's own page; Rolling Hills' own page does not separately name its regional Fire Prevention office, so the Carson-office assignment for Rolling Hills itself is inferred from geographic adjacency, not independently confirmed. 72% · department staff directory + LACoFD regional office list (inference)

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 an eligible expedited residential PV system: a single combined structural/electrical/plumbing inspection by County DPW Building & Safety, performed once the system is fully installed ('One inspection shall be sufficient for the system when satisfactory evidence is submitted to verify that the installation and labeling of components meet requirements of the Building, Electrical, and Plumbing Codes'). Where the project includes an ESS, a separate LACoFD Fire Prevention plan review must be completed and approved BEFORE the County Building & Safety permit submittal, and a separate LACoFD field inspection of the disconnect placarding/ESS installation follows after the County permit issues (LACoFD's checklist requires 'Digital Proof of Construction Permit' as a precondition of its own inspection). 82% · county permitting bulletin + county fire authority checklist

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 88% · county fire authority current inspection checklist + county bulletin
• What must be on site at inspection? Approved plans and permit; manufacturer specification sheets for modules, racking/anchors, and inverter(s) (and full ESS installation manual if an ESS is present and requested by the inspector); photographic/video evidence of any concealed components (roof-mount fastening, grounding/bonding, nameplates, attic conduit clearance); and, for ESS/PV fire inspections, digital proof of the Building & Safety construction permit plus evidence LACoFD's own inspection fee has been paid. 80% · county fire authority current inspection checklist + county bulletin

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.
