City of Hawaiian Gardens

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? City (Community Development Dept./Building & Safety Division, in-house) permits and inspects Building, Electrical, Mechanical and Plumbing for residential PV. Fire-code enforcement, ESS>3kWh, BIPV and all disconnect placarding are delegated to LA County Fire Department (LACoFD), a property-tax-funded contract city per MC 2.52.010 (city requested inclusion in the Consolidated FPD of LA County under H&SC 13948). Fee CALCULATION is delegated in basis (not staffing) to LA County: MC 15.04.050(A) sets fees at the current LA County Building/Electrical/Mechanical/Plumbing Code fee schedule x 1.30. 85% · staff directory
• 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 70% · municipal code
• Is a HOA or architectural approval required first? No -- and the City's own AB 2188 ordinance affirmatively bars conditioning solar approval on HOA sign-off: MC 15.22.060(H): 'Approval of an application shall not be conditioned upon the approval of an association, as defined in Section 4080 of the California Civil Code.' 90% · municipal code
• Is a Specific Use Permit or Council approval ever required? Yes, but at the Director level, not Council: MC 18.90.020(B) requires 'New developments proposing the use of solar energy systems or located adjacent to properties with existing solar energy systems' to 'obtain a minor use permit as outlined in Section 18.100.050' -- a discretionary permit decided by the Community Development Director (appealable to Planning Commission), requiring solar easements from adjacent properties and Fire Department approval. This sits in apparent tension with the ministerial/non-discretionary review Ch.15.22 and Gov. Code section 65850.5 require for eligible small residential rooftop systems -- reported as an unresolved conflict between the City's own zoning and building-code chapters. 80% · municipal code
• Is there a system-size cap on residential generation? 10 kW AC nameplate / 30 kW thermal, codified (unchanged since Ord. 560, 2015), scoped to single- or duplex-family dwellings only. 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 60% · municipal code
• Is a homeowner permitted to self-install and self-permit? Yes 70% · municipal code

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 the checklist/manual AB 2188 path: the 'Submittal Requirements and Eligibility Checklist,' a 'Solar Standard Plan - Central String Inverter System' OR 'Solar PV Standard Plan - Microinverter and ACM Systems,' a 'Structural Criteria Form,' and a 'Building Permit Form.' For the SolarAPP+ path: the SolarAPP+-generated Approval Document, the eligibility checklist, and a single-line drawing, emailed to buildingtech@hgcity.org. 80% · department page
• Is a site plan required, and what must it show? A site plan is implied as part of the required 'Solar Standard Plan' set and the general Building Division's 'Sample Site Plan (B-021)' bulletin, but the exact content requirements could not be confirmed. 50% · department page
• Is a one-line / three-line diagram required? Yes 85% · 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 small residential rooftop solar. No general-purpose online permit portal (e.g. Accela/eTRAKiT/OpenGov) was found for other permit types -- the general Building & Safety page states minor plan checks are done 'over the counter, by appointment only.' 80% · department page
• Can the whole application be completed online? Yes, for SolarAPP+-eligible systems -- design submittal, automated review, fee payment and the approval document are all completed within SolarAPP+ -- though the City additionally requires the applicant to email the SolarAPP+ approval, checklist, and single-line drawing to buildingtech@hgcity.org to finish opening the City's own permit record (not a fully closed-loop automated hand-off). 78% · department page
• What does a residential solar permit cost? $407.57 flat (stated fee for the checklist/AB 2188 expedited small-residential-rooftop-solar path) 70% · department page
• How is the fee calculated? Flat, for AB 2188-eligible small residential rooftop solar (<=10kW AC/30kW thermal, single/duplex dwelling) at $407.57 per the department page. For systems outside that eligibility, MC 15.04.050(A) reverts fees to the current LA County Building/Electrical/Mechanical/Plumbing Code fee schedule x 1.30, which is itself a Valuation-tiered table. 65% · municipal code
• Is there a separate plan-check fee? Yes 90% · municipal code

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 (for a small residential rooftop solar application meeting the City's checklist/standard plan) 92% · municipal code
• How long is an issued permit valid before it expires? Plan check application: expires 1 year from date of application if no permit issued. Permit: expires if work not commenced within 1 year of issuance, or if no required inspection is approved within 1 year of the last approved inspection. Extensions up to 180 days each, cumulative cap 2 years, available on written request plus fee (max 25% of original fee per extension). 92% · municipal code
• Which utility handles interconnection here? Southern California Edison (SCE) 78% · city website (outbound link)

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 75% · municipal code
• Which building code edition is in force? 2025 California Building Code (Chapter 1, Division II through Chapter 35 and Appendices C, F, H, I, J, O, P and Q), Title 24 Part 2 95% · municipal code
• Which fire code edition is in force? Los Angeles County Code Title 32 ('the Fire Code'), 'as amended and in effect on March 2, 2023,' which constitutes an amended version of the 2022 California Fire Code (Part 9 of Title 24 CCR) -- a date-pinned county adoption, distinct and one cycle behind the City's own 2025 Building/Electrical/Mechanical/Plumbing/Residential Code cycle. 92% · municipal code
• Are there local amendments to any of the above? Yes 90% · municipal code
• What is the installation judged against? The 2025 California Electrical Code as adopted/amended by MC Ch.15.08, plus (for the ESS/BIPV/disconnect-placard scope specifically) the LA County Fire Code (Title 32, in effect 3-2-2023 = amended 2022 CFC) enforced by LACoFD. 80% · 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.

• What ridge setback and access pathways are required? Not confirmed with City-specific numeric figures -- MC Ch.15.20 (Fire Code) has no PV-specific ridge-setback or pathway amendment of its own (control-checked: full text of 15.20.010-.040 read, no PV/solar mention). Ridge setback and access pathways for HG, as an LACoFD contract city, are governed by LA County's own Fire Code (Title 32, in effect 3-2-2023) and LACoFD's Guide for ESS, PV and Disconnects (Rev. 2023-09-01). 65% · county fire agency document

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 applies per the adopted 2025 CEC (based on the 2023 NEC), which includes Article 690.12 -- but no HG-specific citation of '690.12' was found anywhere in the local code text (MC Ch.15.08 has no PV-specific electrical amendment). 65% · municipal code

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? For the LACoFD-retained scope (ESS>3kWh, BIPV, and ALL disconnect placarding on every PV job regardless of who performs Building): the 'F.D. - ELECTRICAL / BLDG DISCONNECT / #X of Y' placard, per LACoFD's Guide for ESS, PV and Disconnects (Rev. 2023-09-01). Standard CEC 690/705 AC/DC disconnect and 'Dual Power Sources' warning labels also apply per the adopted 2025 CEC. 75% · county fire agency document
• Does the authority specify placard wording of its own? Yes, for the LACoFD-retained scope: exact wording 'F.D. - ELECTRICAL / BLDG DISCONNECT / #X of Y'. 70% · county fire agency document
• Does it specify letter height, colour or material? Yes, per LACoFD for the retained scope: exterior placards minimum 2 in x 3.5 in, weather-resistant plastic, engraved, red letters on yellow background, all-caps Arial minimum 24-point (28-point for larger placards). 70% · county fire agency document
• Is a site plan / facility map placard required, and what must it show? CEC section 705.12 requires a permanent plaque/directory denoting all electric power sources on the premises (part of the adopted 2025 CEC); LACoFD separately requires its own disconnect placards for the retained scope described above. 60% · municipal code
• Where must the labels be placed? Per adopted 2025 CEC/CFC and, for the LACoFD-retained scope, on the service equipment/main panel and at the PV disconnect(s) per the LACoFD guide's placard spec above. 55% · county fire agency document

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.

• Must equipment be on a specific approved list? Yes 88% · municipal code
• Are batteries permitted, and under what conditions? Yes, with conditions: MC Ch.15.22's definition of 'solar energy system' includes storage as part of a covered system, but batteries/ESS above 3kWh capacity are retained for separate plan review/inspection by LACoFD (LACFC section 1207.11) rather than being processed through the City's expedited Ch.15.22 path. 65% · county fire agency document
• Is there a separate ESS permit or inspection? Yes -- LACoFD requires its own separate plan submittal/review and field inspection for ESS above 3kWh, independent of the City's building/electrical permit and single consolidated inspection under MC 15.22.060(I). 65% · county fire agency document

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 -- (562) 420-2641 ext. 224 (Nicholas Tarango, Building Inspector), by appointment 82% · department page
• How much notice is required? General building inspections: 24 hours advance notice by phone. Small residential rooftop solar under the Ch.15.22 expedited path specifically: 'An inspection will be scheduled within two business days of a request' (a City turnaround commitment, not an applicant notice requirement). 85% · municipal code
• Are same-day or AM/PM windows offered? No AM/PM window choice stated -- 'Building Inspections are conducted on Monday, Tuesday and Thursday between 1:00 p.m. and 4:00 p.m.,' not in any specific order unless prior arrangements are made. 80% · 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 -- the City performs its own consolidated building/electrical final inspection for eligible small residential rooftop solar (MC 15.22.060(I): 'Only one inspection shall be required and performed by the Building Department'). Separately and in addition, LACoFD requires its own fire-department final inspection of the PV/ESS installation prior to use, per an LA County Fire Department memorandum cited on the City's own page -- a split final, not a full delegation of the whole inspection. 82% · department page
• If delegated, to whom? Los Angeles County Fire Department (LACoFD), Fire Prevention Division -- for the fire-safety/PV/ESS final only, not the building/electrical final. 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? 1) City issues the building permit (SolarAPP+ automated review or manual Ch.15.22 checklist review, 3-business-day turnaround); 2) a single consolidated City building/electrical final inspection; 3) a separate, mandatory LACoFD fire-final inspection prior to use of the PV/ESS installation. 80% · department page
• Is a rough-in or mid-roof inspection required? No 85% · 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? Yes -- 'Submittal Requirements and Eligibility Checklist' is a named, linked document on the City's own Building & Safety Division page. 70% · 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.

• What is issued on pass? Final (job-card sign-off) for a PV retrofit to an existing dwelling; a Certificate of Occupancy under MC 15.04.070 is described for new construction/occupancy-classification changes and is not explicitly tied to a solar retrofit. 55% · municipal code
• Is there a re-inspection fee? An inspection fee may be assessed for re-inspection 'as determined per the fee resolution' -- no dollar figure is stated in the code itself. 60% · municipal code
• How are corrections issued and cleared? For the Ch.15.22 expedited path: 'If an application... is deemed incomplete, a written correction notice detailing all deficiencies... shall be sent to the applicant for resubmission' (MC 15.22.060(D)). If a solar system fails inspection, 'a subsequent inspection is authorized but need not conform to the requirements made applicable to the first inspection' (MC 15.22.060(I)(2)). 88% · municipal code
