City of Cudahy

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% · authority's own page
• What does this authority permit itself, and what does it delegate? Both 88% · authority's own page
• Is a permit required for a residential rooftop PV system? Yes 95% · published bulletin
• Is there a separate electrical permit, or is it combined? Separate 90% · authority's own page
• Is a HOA or architectural approval required first? No — explicitly barred 92% · municipal code
• Is there a historic-district review? No 80% · municipal code
• Is a Specific Use Permit or Council approval ever required? Yes, conditionally: if the building official finds, on substantial evidence, that the system could have a 'specific, adverse impact' on public health/safety, a use permit is required (appealable to the Planning Commission). 92% · municipal code
• Is there a system-size cap on residential generation? 10 kW AC nameplate rating or 30 kW thermal, scoped to duplex or single-family dwellings only, panels not to exceed the maximum legal building height 95% · 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 85% · permit application form
• Must the contractor be registered with this authority before applying? Yes (inference) 55% · fee schedule
• Is a homeowner permitted to self-install and self-permit? Yes 85% · permit application form

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 permit application form; demonstrated compliance with the Eligibility Checklist for Expedited Solar PV Permitting; a completed Solar PV Standard Plan (micro- or string-inverter version); a roof plan showing roof layout, PV panels, roof-access point, code-compliant access pathways, PV fire classification and label locations; and a completed Structural Criteria worksheet with supporting documentation. 92% · published bulletin
• Is a site plan required, and what must it show? Yes — a roof plan is required showing roof layout, all PV panels/modules, clear access pathways, approximate location(s) of electrical disconnecting means, and roof access points; the Structural Criteria worksheet separately requires a module/anchor layout roof plan. 88% · published checklist
• Is a one-line / three-line diagram required? Yes 85% · standard plan
• Are string and conductor calculations required? Yes 80% · standard plan
• Is a structural PE stamp required, and at what threshold? Yes, threshold = failing any item on the prescriptive Structural Criteria checklist. Text: 'One or more items are checked NO. Attach project-specific drawings and calculations stamped and signed by a California-licensed Civil or Structural Engineer.' 90% · published 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+ (solarapp.nrel.gov) for eligible rooftop residential PV; no other online permit portal was found for general building/electrical permits 92% · authority's own page
• Can the whole application be completed online? No — not end-to-end. SolarAPP+ handles eligible design submittal and automated review online, but the city's own page routes inspection scheduling to phone/email and permit fee payment/issuance requires an in-person City Hall visit. 85% · authority's own page
• What does a residential solar permit cost? $204.48 flat (plan-check component only, 2015-dated); total building+electrical permit fee is valuation-based per the city's Master Fee and Fine Schedule (LA County valuation table less 10% per Resolution 99-34) and is not separately quantified for a typical residential PV system anywhere published. 55% · published bulletin
• How is the fee calculated? Valuation (LA County valuation-based Building/Electrical permit tables, reduced 10% per city Resolution 99-34) 70% · fee schedule
• Is there a separate plan-check fee? Yes — $204.48 (2015-dated) 80% · published 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? 3 business days from the application being deemed complete 95% · municipal code
• How long is an issued permit valid before it expires? 180 days (permit becomes null and void if work not commenced within 180 days of issuance, or abandoned for 180 days after commencement) 88% · permit application form
• Which utility handles interconnection here? Southern California Edison (SCE) 95% · authority's own 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? 2020 NEC, adopted as the 2022 California Electrical Code 75% · municipal code
• Which building code edition is in force? 2022 California Building Code as amended by Title 26 of the 2022 Los Angeles County Building Code 88% · municipal code
• Which fire code edition is in force? 2016 California Fire Code as amended by Title 32 of the 2017 Los Angeles County Fire Code 85% · municipal code
• Are there local amendments to any of the above? Yes 88% · municipal code
• What is the installation judged against? The 2022 CBC/CEC as amended by LA County Titles 26/27, plus the city's own Solar PV Standard Plan, Structural Criteria worksheet and Eligibility Checklist for the expedited path; the LA County Fire Code (LACFC) for the ESS/BIPV/disconnect-placarding scope LACoFD retains. 82% · authority's own 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.

Nothing recorded for City of Cudahy 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.

Nothing recorded for City of Cudahy on this step yet — 1 question checked and found unpublished. The guidance above is general.

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: CEC-mandated DC/AC disconnect and dual-power-source warning placards (per the Standard Plan, citing CEC 690.53/690.54/705.12), PLUS, for the LACoFD-retained scope on every PV job, an 'F.D. – ELECTRICAL / BLDG DISCONNECT / #X of Y' exterior placard and matching panel-interior placard at every electrical power-source disconnect. 88% · fire agency's own guide
• Does the authority specify placard wording of its own? Yes, for the disconnect placards — LACoFD dictates exact verbiage; the city's own Standard Plan reproduces the generic CEC-mandated warning-label wording rather than inventing its own. 88% · fire agency's own guide
• Does it specify letter height, colour or material? Yes, for the LACoFD disconnect placards: exterior placards min 2"x3.5", weather-resistant plastic, verbiage engraved, red letters on yellow background, Arial all-caps, minimum font size 24 (28 bold for 'F.D.'/'#X of Y'); panel-interior placards min 7/16"x3/4", same colour/font rules; attached with permanent epoxy. 95% · fire agency's own guide
• Is a site plan / facility map placard required, and what must it show? Yes — a permanent directory/plaque denoting all electric power sources on the premises (CEC 705.12) is required per the Standard Plan; separately, LACoFD requires a written 'Disconnect Schedule' listing every disconnect (#X of Y) and its location as part of any ESS/BIPV submittal. 80% · standard plan
• Where must the labels be placed? At/adjacent to each disconnect enclosure or panel that must be operated to isolate the structure from a power source (exterior placards on/immediately adjacent to the enclosure; panel-interior placards inside the panel identifying specific breakers where multiple switches in one panel require operation). 88% · fire agency's own 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.

• Must equipment be on a specific approved list? No dedicated city approved-equipment list; only the standard CEC/UL listing requirement applies. 75% · standard plan
• Are batteries permitted, and under what conditions? Yes, with conditions. The city's own expedited/SolarAPP+ eligibility path explicitly excludes battery storage ('Solar system is utility interactive and without battery storage'; Standard Plan: 'not intended for ... systems that utilize storage batteries'). Batteries/ESS are separately governed by LACoFD: individual units capped at 20 kWh, aggregate 80 kWh per site (garage/exterior-wall/outdoor-ground locations), impact protection required below 36" height, garage smoke/heat detection, and mandatory LACoFD plan review plus field inspection for any capacity, with LACoFD field inspection required above 3 kWh. 90% · fire agency's own guide
• Is there a separate ESS permit or inspection? Yes — LACoFD requires its own separate plan submittal/approval and field inspection for ESS (mandatory LACoFD inspection above 3 kWh capacity), independent of the city Building Department's building/electrical permit and single inspection. 88% · fire agency's own checklist
• Is a ground mount treated as a structure? Not directly addressed for solar; ground-mounted systems are excluded from the city's expedited/SolarAPP+ eligibility path entirely ('No ballasted or ground mounted systems'). By inference, a ground-mounted array would likely be treated under the zoning code's generic Accessory Structures standard (CMC 20.16.090: 18 ft height cap, 5 ft interior side/rear setback), since no solar-specific ground-mount provision exists in Title 20. 55% · authority's own page
• Is there a local rule on service upgrades or busbar sizing? 225A maximum busbar rating for the single-phase 120/240V service the PV system interconnects to (an eligibility-path threshold, not a distinctly local ordinance amendment) 65% · published checklist
• Is a specific mounting system or attachment spacing required? Yes — detailed flush-mount attachment/anchor-spacing standard: 2"-10" gap under modules, array ≤4 psf (PV)/5 psf (thermal), ≤half of total roof area, anchor horizontal spacing per Table 1 (varies by roof slope 0-63° and rafter spacing 16/24/32" o.c.), 5/16" lag screw with 2.5" rafter embedment (or per manufacturer), roof-slope/rafter-span checks with an optional rafter-span table (Table 2, by construction vintage pre/post-1960). 85% · published 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 (online form) or Phone 92% · authority's own page
• How much notice is required? 24 hours 90% · authority's own page
• Are same-day or AM/PM windows offered? Yes — Morning Inspections 7 AM-12 PM, Afternoon Inspections 1 PM-5 PM, Monday through Thursday (city on a 4-day work week; closed Fridays). 92% · authority's own 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, for conventional rooftop PV — 'Only one inspection shall be required and performed by the building department for small residential rooftop solar energy systems eligible for expedited review.' LACoFD performs its own separate field inspection for ESS above 3 kWh and BIPV, which is not delegated to the city. 88% · municipal code
• If delegated, to whom? Los Angeles County Fire Department (LACoFD), for ESS above 3 kWh and BIPV only; not delegated for conventional rooftop PV. 88% · fire agency's own guide

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? Building + electrical permits issued together (within 3 business days of a complete application) -> installation -> single final inspection by the Building Department (scheduled within 2 business days of request) for conventional PV. If ESS/BIPV is involved, a separate LACoFD plan submittal, approval, and field inspection is required in addition, scheduled directly with LACoFD's regional Fire Prevention inspection office. 80% · municipal code
• Is a rough-in or mid-roof inspection required? No 88% · 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 78% · published bulletin
• What must be on site at inspection? Approved plans and permit; conformance with all technical requirements checked in the field 65% · published bulletin
• Does the inspector verify labels and listings? Yes 85% · published 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.

• What is issued on pass? Final (building final inspection sign-off) — inferred, not stated in exact CO/Final/Green-tag/Letter terms by the city. 50% · authority's own page (inference)
• Is there a re-inspection fee? No line item named specifically 're-inspection fee'; the applicable general basis appears to be the Master Fee Schedule's generic hourly rate 'For inspection for which no fee is specifically indicated, per hour — $91.62' (2015-dated). 50% · fee schedule
• How are corrections issued and cleared? Written correction notice detailing all deficiencies, issued by the building department on an incomplete application; if a system fails the single required inspection, a subsequent (re-)inspection is authorized outside the normal 2-business-day scheduling guarantee. 82% · municipal code
