What is the LA County ADU Electrical Inspection Process?
ADU electrical inspections occur at multiple stages:
1. Rough-In Inspection
Conducted after wiring is installed but before walls are closed up.
Inspectors check conduit, wire sizing, grounding, and bonding.
Outlets, junction boxes, and fixture placements are reviewed.
2. Service Panel Inspection
Verifies proper panel installation and capacity for the ADU.
Ensures correct circuit labeling and secure connections.
Confirms compliance with NEC (National Electrical Code) and California Electrical Code.
3. Final Inspection
Conducted after all electrical work is complete, including outlets, switches, lighting, and appliances.
Confirms GFCI/AFCI protection in required areas.
Checks proper mounting of electrical boxes and fixtures.
Validates smoke and carbon monoxide detector wiring.
How to Prepare for Your LA County ADU Electrical Inspection

✔️ Keep your permit and approved plans on-site for the inspector’s reference.
✔️ Clearly label all circuits in the electrical panel for easy identification.
✔️ Confirm proper installation of GFCI and AFCI protection where required.

During an ADU electrical inspection, unexpected challenges can occur, such as:
Relocation of the Electrical Panel: The city may require an alternate panel placement for better access.
Additional Grounding Requirements: Some jurisdictions require extra grounding rods or bonding.
Circuit Adjustments: Inspectors may require load balancing on circuits to prevent overloading.
