Every state has different rules. Some require permits for any work beyond changing a light switch. Others let homeowners do their own panel upgrades. Find your state below.
Every jurisdiction requires a permit for service upgrades. Expect inspection before utility reconnects.
Adding a new 20A kitchen circuit or running wire to a garage? Permit needed in 48/50 states.
Like-for-like replacements (same location, same type) are exempt in most jurisdictions.
New 240V circuit + new breaker = permit required. Some states also need a separate EV inspection.
Replacing an existing fixture on an existing box is exempt. Adding a new fixture location requires a permit.
New sub-panel in garage or workshop? Permit + inspection required everywhere.
Transfer switch install requires a permit. Interlock kits may also need inspection depending on AHJ.
Some states allow homeowner-pulled permits. Others require a licensed electrician for all permitted work.
Authority Having Jurisdiction = your local building department. Rules vary even between neighboring cities. A 5-minute phone call saves weeks of headaches.
Home inspectors flag unpermitted electrical. Buyers negotiate $5K–$15K off or walk. The $100 permit is the cheapest insurance you'll ever buy.
If a fire traces back to unpermitted electrical work, your homeowner's insurance can deny the claim. Every single time.
