The inspection is the building department's check that the work meets code. For most homeowners it is short and uneventful, but it helps to know what to expect.
What does the electrical inspector check?
- That the work matches the permit, with the right breaker and wire sizes.
- Grounding and bonding, working clearances around the panel, labels and the panel directory.
- Required AFCI and GFCI protection, tamper-resistant outlets and, where triggered, smoke and CO alarms.
- For service upgrades: the meter base, service mast or underground conduit, and the main disconnect.
Larger projects have a rough-in inspection before walls are closed and a final inspection after.
Do I need to be home for the inspection?
Usually, yes. Inspectors often need access to the panel, the inside of the house and sometimes the attic, and many inspections also check smoke and CO alarms inside. For IES panel and service upgrades, the customer needs to be home for the inspection.
What if it fails?
The inspector leaves a correction notice. The contractor makes the corrections and schedules a re-inspection. For service upgrades, the utility generally reconnects permanent power only after the inspection is approved.
Common questions
How long does an electrical inspection take?
Many residential electrical inspections are short. Larger projects have more than one inspection.
Do I have to be home for an electrical inspection?
Often yes, because the inspector needs access inside the home. For IES panel and service upgrades, the customer needs to be home.
General information for California homes under the California Electrical Code (based on the NEC). Local rules and inspectors can vary. Not a substitute for an on-site inspection. Never work inside a panel, at the meter or on live circuits.
