Can I legally do my own electrical work?

You can legally do your own electrical work in most US states, on a house you both own and live in, after pulling a homeowner permit and passing inspection. That owner-occupant carve-out is the standard shape of the law.

The boundaries are real. Rentals and flips usually require a licensed electrician. Some states and cities allow almost nothing without a license, and utility-side work is never yours to touch.

The permit is not the enemy. It buys you an inspector who catches mistakes before drywall hides them, and it protects your insurance claim and your resale disclosure later.

Rules vary enough that the first call goes to your local building department, not a forum.

Do the math like a pro before the inspector arrives: the free electrical calculator cites the NEC article behind every answer.
