Do I need a permit for electrical panel or service upgrade in Knoxville?
Yes. In Tennessee, electrical panel or service upgrade generally requires a permit, and Knoxville is no exception.
Panel replacements and service upgrades require an electrical permit and inspection; the utility typically will not reconnect power after a service change until the inspection passes. A service change may also require coordination with the electric utility for a temporary disconnect and reconnect; confirm the sequence with your local codes department or state issuing agent. Electrical permits inside the city are issued by the City of Knoxville, applied for through the permits.knoxvilletn.gov portal, so a panel or service upgrade is not exempt. A meter or service change usually requires coordination with the local electric utility for disconnect and reconnect after the city inspection passes. Tennessee limits homeowner electrical work and requires a licensed electrician for most jobs, so confirm eligibility with Knoxville Plans Review and Inspections before applying.
