Electrical permits are the second-highest volume permit type in California after solar, and they span a wide range of project types — from simple EV charger installations to full service upgrades and panel replacements. Understanding what each type requires, how long it takes, and where contractors most commonly make mistakes is essential for running an efficient electrical contracting operation in California.
When is an electrical permit required in California?
California requires permits for virtually all electrical work beyond simple like-for-like fixture replacements. Projects that always require a permit:
- Service panel replacement or upgrade (100A to 200A, 200A to 400A, etc.)
- New branch circuit installation
- EV charger installation (Level 1, Level 2, or DCFC)
- Generator installation with transfer switch
- New subpanel installation
- Solar-related electrical work (inverter, disconnect, new circuits)
- Battery storage system electrical connections
- New electrical service installation
Panel replacement permit requirements
Panel replacement is one of the highest-volume electrical permit types in California. Standard submittal requirements:
- Permit application with C-10 contractor license number
- Load calculation showing existing and new load
- One-line diagram showing service entrance, main breaker, and new panel configuration
- Equipment specifications for new panel (make, model, ampacity, interrupt rating)
- Utility notification documentation in many jurisdictions
AFCI and GFCI requirements: California's 2022 electrical code requires AFCI protection on nearly all branch circuits in dwelling units and GFCI protection in all wet locations. Panel replacements trigger a full code compliance review — the new panel must meet current code, not just replace the old one like-for-like.
Service upgrade permits
Upgrading from 100A to 200A service (or 200A to 400A for larger homes) involves both a permit and utility coordination:
- Electrical permit for the internal panel and wiring work
- Utility coordination for meter socket and service entrance changes (SCE, PG&E, or LADWP depending on location)
- Utility inspection before energization in many jurisdictions
EV charger permit requirements
California's SB 1236 created a streamlined permitting process for qualifying Level 2 residential EV charger installations. For eligible projects, many cities process permits in 3–5 days instead of the standard electrical permit queue. Eligibility requires: residential single-family property, Level 2 EVSE (not DCFC), installation meeting standard load requirements. Using the standard electrical permit form instead of the streamlined form for an eligible project means waiting in the full queue unnecessarily.

Inspection requirements for electrical permits
Most California electrical permits require a rough-in inspection (before walls are closed) and a final inspection. Key inspection checkpoints: all work matches approved plans, AFCI/GFCI protection correctly installed, grounding and bonding complete, panel labeled correctly, permit posted on-site. Utility inspection may also be required before re-energization.
