City of Paramount

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% · adopting ordinance + department page
• What does this authority permit itself, and what does it delegate? Both — City of Paramount Building and Safety Division (part of the Planning and Building Department) issues and reviews both the building and electrical permit for residential rooftop PV itself; it does not delegate general PV building/electrical permitting. Fire-code aspects are split: LACoFD historically delegates conventional rooftop-PV fire review to the city, but retains ESS/BIPV plan review and disconnect-placarding/rapid-shutdown-activation inspection for ALL residential PV as the fire AHJ. 90% · department page + county fire guidance document
• Is a permit required for a residential rooftop PV system? Yes 97% · adopting ordinance
• Is there a separate electrical permit, or is it combined? Combined — a single City of Paramount permit (one permit number) is issued per project; the Master Fee Schedule itemizes Building Permit and Electrical Permit fee components separately within that process, and SolarAPP+ issues one permit number for the automated review. 70% · department page + fee schedule
• Is a HOA or architectural approval required first? No — the city ordinance explicitly bars conditioning approval on HOA/association approval, consistent with the Solar Rights Act. 90% · adopting ordinance
• Is there a historic-district review? No historic-district/preservation review chapter was found for Paramount. 65% · municipal code (table of contents)
• Is a wind or windstorm certification required? No — not applicable. Paramount is inland Los Angeles County; windstorm/hurricane certification (a Texas TDI-style requirement) is not part of California's adopted codes here. 80% · adopting ordinance
• Is a Specific Use Permit or Council approval ever required? Only if the Building Official makes a written finding, based on substantial evidence, that the system could have a 'specific, adverse impact' on public health/safety — in that case a discretionary Use Permit is required, appealable to the Planning Commission. Otherwise the process is purely ministerial/administrative. 90% · adopting ordinance
• Is there a system-size cap on residential generation? The ordinance's streamlined/expedited process applies only to a 'small residential rooftop solar energy system,' defined as not larger than 10 kW AC nameplate rating (or 30 kW thermal), on a single- or duplex-family dwelling, not exceeding the maximum legal building height. Larger residential systems remain permittable but fall outside this chapter's ministerial process (and may trigger the discretionary Use Permit path under §15.08.060(A) if an adverse-impact finding is made). 85% · adopting ordinance

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 — a California C-10 licensed electrical/solar contractor, or the homeowner-builder residing in the single-family residence, may pull the permit (electrical work is part of the same permit). 90% · department page
• Must the contractor be registered with this authority before applying? Yes, in practice — a current City of Paramount business license and CSLB license/Workers' Comp certificate must be on file/uploaded at time of permit issuance for a contractor (not a formal pre-registration program, but the license and city business license are checked at application). 80% · department page
• Is a homeowner permitted to self-install and self-permit? Yes 90% · 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? No Paramount-specific solar submittal checklist was found; the city instead directs SolarAPP+-eligible projects to the national SolarAPP+ PV Eligibility Checklist (design must include the standard SolarAPP+ document set — site plan, one-line diagram, equipment spec sheets, structural attachment info). Non-SolarAPP+ projects follow the standard building-permit submittal (site/floor plans, structural calcs where applicable) via the iWorq portal. 55% · department page
• How many copies, and in what format? Electronic submittal only, via the SolarAPP+ portal or the general iWorq online permit application; in-person paper submittal remains available as an alternative at the Building & Safety counter. No specific number of paper copies is published. 55% · department page
• Is a one-line / three-line diagram required? Yes (inferred) 65% · department page / SolarAPP+ platform standard
• Are string and conductor calculations required? Yes (inferred) 60% · department page / SolarAPP+ platform standard

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: iWorQ (paramount.portal.iworq.net) for general permit application, fee payment, plan-check status and inspection scheduling; and SolarAPP+ (solarapp.nrel.gov, via the city's dedicated 'Solar App+' page) specifically for automated instant solar plan review/permitting. 95% · department page
• Can the whole application be completed online? Yes, for SolarAPP+-eligible projects — full online design submittal, automated code-compliance review, instant approved plans, and City permit-fee payment, entirely online. General building permit applications are also stated to be submittable online in full via iWorq. Note a tension: the codified ordinance text at §15.08.060(B) still says the City 'shall not accept the electronic submittal of a solar energy system permit application...until such time that the City accepts the electronic submittal of all building permit applications' — the city's current live practice (SolarAPP+ + 'online submittals are available for all permit applications') appears to have satisfied that condition, but the ordinance text itself has not been updated to remove the restriction. 80% · department page + adopting ordinance (compared)
• What does a residential solar permit cost? No flat/dedicated solar permit fee exists in the current Master Fee Schedule (effective 2/1/2025, Reso. 24-040). Cost is calculated as: Building Permit + Plan Check fee from the Valuation Table (for the racking/structural work, keyed to declared project valuation) + Electrical Permit fee from the 'Power apparatus (rated in kW)' tier for the inverter, + a flat $57.00 permit-issuance fee, + a 7.5% Technology Fee surcharge. For a typical residential system the combined total commonly falls in the low-to-mid hundreds of dollars, but there is no single quoted number. 80% · fee schedule
• How is the fee calculated? Valuation-based (Building Permit + Plan Check, per the Valuation Table) combined with Tiered-by-kW (Electrical Permit 'power apparatus' schedule for the inverter rating). 88% · fee schedule
• Is there a separate plan-check fee? Yes 90% · 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? Typically about 10 business days for a first plan-check submittal; 5-7 business days for resubmittals/revisions. SolarAPP+-eligible submittals receive an automated/instant approval with the City permit number emailed within 24 business hours. 88% · department page
• How long is an issued permit valid before it expires? 12 months from issuance if work is not commenced (or 180 days of suspension/abandonment after commencement), per the locally-amended CBC §105.5; the Building Official may grant extensions of up to 180 days each, for a fee equal to 25% of the permit fee. 92% · adopting ordinance
• Which utility handles interconnection here? Southern California Edison (SCE) 97% · city utilities page
• Where does the utility sit in the sequence? Likely Parallel — the SCE interconnection application is typically submitted independently of the building-permit process, but SCE will not grant Permission to Operate (PTO)/energize the system until the AHJ's final inspection has passed. 50% · utility page (dead link, noted)

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 NEC, incorporated as part of the 2025 California Electrical Code, which the City adopted (with amendments) under Ch. 15.04.010/.013, Ord. 1208, effective 11/18/2025. Note: a separate, unreconciled legacy chapter (Ch. 15.20, last amended by Ord. 1170 in 2023) still literally reads '2022 California Electrical Code adopted' — the later, more specific Ch. 15.04 amendment (which lists the 2025 CEC among the codes making up the current Building Standards Code) controls, but the code has not been cleaned up to remove the stale Ch. 15.20 language. 78% · adopting ordinance
• Which building code edition is in force? 2025 California Building Code and 2025 California Residential Code 95% · adopting ordinance
• Which fire code edition is in force? 2022 California Fire Code, as codified locally at Ch. 15.60.010 (Ord. 1172 §7, 2023). The fire AHJ for PV/ESS review (LACoFD) currently operates under the '2023 LACFC' — the 2022 CFC plus LA County amendments, codified as LA County Code Title 32, certified effective 2024-01-11 — per LACoFD's own Sept-2023 ESS/PV guide and its Appendix QQ fee schedule (re-issued 2025). Note: Paramount's own Ch. 15.04.010 also nominally lists 'California Fire Code' among the 2025-edition codes it adopts, without a corresponding update to the standalone Ch. 15.60 chapter — the same kind of unreconciled cross-reference seen in the Electrical Code chapters. 75% · adopting ordinance + county fire code fee schedule
• Are there local amendments to any of the above? Yes — e.g. a local amendment to NEC Article 690.13(A) requiring the PV AC disconnect within 3 feet of the meter; a local amendment to CBC §105.5 on permit expiration/extensions; LA County's own amendments to the 2022 CFC (creating the 2023 LACFC) governing ESS placement, spacing, and the LACoFD disconnect-placarding system. 92% · adopting ordinance
• What is the installation judged against? The 2025 California Building Standards Code (CBC/CRC/CEC/CMC/CPC/CGBSC/CEnC) as locally amended under Ch. 15.04, plus the solar-specific requirements of Ch. 15.08 (UL/IEEE/CEC listing and performance standards, CPUC safety/reliability rules), and — for fire/ESS/disconnect aspects — the 2022 CFC as amended by LA County (2023 LACFC) enforced by LACoFD. 90% · adopting ordinance

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 Paramount 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.

• Is rapid shutdown required, and to which NEC edition? Yes — rapid shutdown is required per NEC 690.12, incorporated through the 2025 California Electrical Code (based on the 2023 NEC) that the City adopted under Ch. 15.04.010. The City's only local amendment to Article 690 addresses AC disconnect location (690.13(A)), not the rapid-shutdown requirement itself, and no pre-2019/legacy rapid-shutdown language was found in any Paramount document. 80% · adopting ordinance

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 each required electrical power-source disconnection means (main service, PV, and any ESS) and at the rapid-shutdown/hazard-control-system activation switch(es): an 'F.D. — ELECTRICAL BLDG DISCONNECT #X of Y' Exterior Placard on/near each panel or standalone disconnect that must be operated, plus Panel-Interior Placards identifying specific breakers/switches within a shared panel. This is the LACoFD Electrical Power Source Disconnect Placarding System, which applies LA-County-wide (including Paramount) to all one- and two-family dwellings with PV and/or ESS. 90% · county fire department guidance document (Appendix B)
• Does the authority specify placard wording of its own? Yes 92% · county fire department guidance document (Appendix B)
• Does it specify letter height, colour or material? Yes, precisely specified: Exterior placards minimum 2 in. tall x 3.5 in. wide, weather-resistant plastic, verbiage engraved, solid all-capitals Arial font minimum size 24 ('F.D.' and '#X of Y' bold, minimum size 28), red letters engraved into a yellow background, attached with permanent weather/surface-compatible epoxy. Panel-Interior placards minimum 7/16 in. tall x 3/4 in. wide, same color scheme, Arial bold minimum size 24. 92% · county fire department guidance document (Appendix B)
• Is a site plan / facility map placard required, and what must it show? No dedicated 'facility map' placard distinct from the disconnect-placarding system was found; where a project requires plan submittal to the Fire Department, a 'Disconnect Schedule' (a table listing each power source, its disconnect location, and the '#X of Y' designation) must be included in the plan set, which functions as the facility-map/directory of power sources required by NEC 705.10. 65% · county fire department guidance document (Appendix B)
• Where must the labels be placed? Exterior Placards: on the exterior of, or immediately adjacent to, each electrical panel/enclosure or standalone disconnect switch that must be operated to accomplish disconnection (additional placards required if a panel houses multiple sub-panels or switches). Panel-Interior Placards: inside the panel, next to the specific breaker(s)/switch(es) that must be operated, when multiple switches share one enclosure. Exact placement is determined by a C-10 electrician subject to fire-code-official approval. 90% · county fire department guidance document (Appendix B)

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? A single, visible-open, lockable AC disconnect must be located within 3 feet of the electric meter, on the exterior of the building. (This is a Paramount-specific local amendment to NEC Article 690.13(A); it is more specific/restrictive than the general LA County Fire Code §509.3 rule — cited elsewhere as a roughly 6-ft-of-the-main-panel rule for electrical hazard attenuation devices generally — which is a separate fire-code provision rather than the electrical-code disconnect-location rule that governs here.) 93% · adopting ordinance (local NEC amendment)
• Must equipment be on a specific approved list? Yes 85% · adopting ordinance
• Are batteries permitted, and under what conditions? Yes, subject to LA County Fire Code conditions: ESS units may be installed inside a detached garage; inside an attached garage if separated from living/sleeping space per CRC §R302.6; or outdoors/on the exterior building wall meeting distance requirements (LACFC §1207.11.3.1). ESS may NOT be installed inside dwelling units (incl. ADUs), sleeping units, spaces opening into sleeping rooms, closets, bathrooms, basements, non-garage accessory structures, or vaults. Units must be spaced at least 3 ft apart (unless a lesser distance is manufacturer-documented and AHJ-approved), and a Remote Disconnect Device is required for any interior-installed unit. 90% · county fire department guidance document
• Is there a separate ESS permit or inspection? Yes — LACoFD requires its own ESS plan review (except where state-mandate-exempt) and, in all cases, its own field inspection and approval for ESS/BESS at one- and two-family dwellings, in addition to whatever the city's building/electrical permit covers. LACoFD's Appendix QQ fee schedule prices this separately (Energy Storage System, Group R-3/R-4: plan review $565.00 general ESS tier, or the R-3/R-4-specific field inspection at $195.00 under the Special Systems table; a general 'Energy Storage System' field inspection is $390.00 outside R-3/R-4). 90% · county fire code fee schedule

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 (iWorq online scheduling, available up until 4:00 PM the day before) or Phone ((562) 220-2036, must speak to a live person — voicemail requests are not accepted). 92% · department page
• How much notice is required? For online requests: up until 4:00 PM the business day before the desired inspection date (after 4:00 PM the request is pushed to two business days later). For phone requests: must call the business day before, 8:00 AM-4:00 PM. 90% · department page
• Are same-day or AM/PM windows offered? Yes — Morning window 8:00-8:30 AM call-in confirmation for a morning/afternoon time frame; Morning Inspections generally 8:30 AM-12 PM, Afternoon Inspections 12:30-4 PM. 88% · 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? Delegated (split) — City of Paramount Building & Safety performs the general/final PV building-and-electrical inspection (a single consolidated inspection for expedited-eligible systems, per Ch. 15.08.060(H)); Los Angeles County Fire Department separately performs a mandatory field inspection of ESS/BIPV components and the disconnect-placarding/rapid-shutdown-activation system on ALL residential PV, which the applicant must schedule directly with LACoFD. 90% · county fire department page
• If delegated, to whom? Los Angeles County Fire Department (LACoFD), Fire Prevention Division — for ESS/BIPV and disconnect-placarding/rapid-shutdown aspects only; general PV building/electrical final inspection remains with City of Paramount Building & Safety. 90% · county fire 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 of Paramount Building & Safety: a single consolidated final inspection covering roof-mount attachment and electrical work, for expedited-eligible small residential rooftop solar (Ch. 15.08.060(H)). (2) Separately and in addition, for any ESS/BIPV component: LACoFD Fire Prevention field inspection, which must be scheduled and passed 'prior to use' of the PV or ESS installation. 85% · adopting ordinance + county fire department page
• Is a rough-in or mid-roof inspection required? No — for systems eligible for the expedited/ministerial process, the ordinance requires only one Building & Safety inspection, not a separate rough-in/mid-roof inspection. 82% · adopting ordinance

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, on the fire side — LACoFD publishes an 'Expedited-Permitting-Checklist' specifically for ESS/PV/Disconnects. No equivalent Paramount Building & Safety-published solar inspection checklist was found among its Resources/Handouts list (checked and absent). 75% · county fire department checklist
• What must be on site at inspection? The City of Paramount permit number, the type of inspection requested, the project address, and a site contact name and phone number. 82% · department page
• Does the inspector verify labels and listings? Yes (inferred) — LACoFD's field inspection explicitly reviews 'product listings' for both PV and ESS components as part of its scope; equipment/UL listing compliance is also a Ch. 15.08.040(C) requirement the Building inspection is checking against. 80% · county fire 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? Likely 'Final' (the permit is 'finaled' by the inspector) rather than a reissued Certificate of Occupancy, consistent with standard California practice for an alteration to an existing single-family dwelling; Paramount's own materials do not use one of the standard labels explicitly. 50% · department page (inference, not stated verbatim)
• Is there a re-inspection fee? City of Paramount Building & Safety re-inspection fee: $406.00 flat. Separately, LACoFD's fire-side re-inspection fee (after an initial inspection and one reinspection) is $98.00. 90% · fee schedule
• How are corrections issued and cleared? For solar specifically: if an application is deemed incomplete, the Building Department sends a written correction notice detailing all deficiencies and any additional information needed. Generally, inspector corrections for any project can be looked up online by entering the permit/job-card number via a link on the Building & Safety Resources page. 85% · adopting ordinance + department page
