Electrical permits in Unincorporated Los Angeles County, CA
A plain-English starting point for electrical contractors working in Unincorporated Los Angeles County. This is general California guidance — it does not replace the requirements published by the county.
Short answer
In California, most electrical work beyond a like-for-like device or fixture swap needs a permit from the local building department, generally pulled by a licensed C-10 contractor — panel upgrades, new or extended circuits, service changes, EV chargers, and solar/battery interconnection all typically require one. The governing code is the California Electrical Code (Title 24, Part 3, based on the NEC).
Unincorporated Los Angeles County-specific fees, forms, and timelines are set by Los Angeles County Public Works — Building and Safety Division. Verified data — portal, fee schedule, adopted code — is sourced below.
The general picture
California electrical work is governed by the California Electrical Code (Title 24, Part 3, based on the NEC). Most electrical work beyond like-for-like repair — panel upgrades, new circuits, service changes, EV chargers, solar interconnection — generally requires a permit from the local building department, and a licensed C-10 contractor is typically involved. Exact submittal requirements, fees, and review timelines are set by each city and are not standardized statewide — confirm them with the jurisdiction below before you file.

- Service panel upgrades
- Rewires and circuit additions

Usually doesn't (general norm)
- Replacing a single switch, receptacle, or light fixture like-for-like
- Swapping a breaker for one of the same rating and type
- Repairing a damaged section of existing wiring with the same type and capacity
- Most low-voltage work (thermostats, doorbells) — often, but not universally
Documents & plans generally required
- Completed building/electrical permit application
- Contractor's license and city business/registration info
- Site or floor plan showing the affected areas (larger scopes)

Common reasons electrical applications get bounced
These are general, code-rooted patterns across California — not a Unincorporated Los Angeles County rejection rate.
- Load calculations missing or not matching the proposed service size
- No single-line diagram for a service or panel change
- Scope on the application doesn't match the plans (e.g., panel-swap application but drawings add circuits)
- Equipment not listed/labeled to a recognized standard, or no cut sheets
- PV/battery work submitted without the required interconnection or utility documentation
The inspection sequence
A typical order — the number of stops and exact sequence vary by jurisdiction and scope.
- 1Rough/in-progress inspection before walls or trenches are closed
- 2Service or temporary-power coordination with the utility where applicable
- 3Final inspection with the panel labeled and the work energized and tested
Licensing — who can pull it
Electrical work in California is generally performed by a C-10 (Electrical) licensed contractor; a licensed B (General Building) contractor may pull it within a larger project under CSLB rules. The permit is typically pulled by the licensed contractor doing the work. Licensing and who may pull a permit are governed by the CSLB and the local department — not by getPermit.

Frequently asked questions
Do I need a permit to replace an electrical panel in California?
Generally yes. A panel or service upgrade changes the building's electrical service and almost always requires an electrical permit and an inspection, with load calculations and a single-line diagram. The exact submittal format and fees are set by the city — confirm with the building department linked below.
Does an EV charger install need a permit?
In California a hardwired Level 2 EV charger generally needs an electrical permit because it adds a dedicated circuit and load. Some cities offer a streamlined EV-charger permit. Confirm the local process with the AHJ below.
Can I do permitted electrical work without a C-10 license?
For permitted commercial trade work, the permit is generally pulled by a licensed contractor — typically a C-10, or a B general contractor on a larger project. Licensing rules are set by the CSLB and the local department.
Is a permit required for a like-for-like fixture swap?
Usually not — replacing a single switch, receptacle, or light fixture with the same type is generally treated as maintenance in most California jurisdictions. This is a general norm, not a guarantee; a few cities are stricter. Check the city below.
