What to know about electrical permits in Tennessee
Electrical permits in Virginia cover new wiring, service upgrades, and added circuits, while simple device swaps are often exempt. Costs vary by locality and scope. A licensed electrician is strongly recommended, because electrical work is a common cause of inspection failures and safety issues.
The application steps and inspection sequence for electrical permits come from the model code rather than from Tennessee law, so they read the same wherever you build. We keep that walkthrough in one place: how an electrical permit application and its inspections work, start to finish. What changes between Tennessee jurisdictions is below: who requires a permit, what they charge, and which office you file with.

What an electrical permit costs in Tennessee
3 Tennessee jurisdictions we cover publish a fee figure for this work. Each line is quoted from that office's own schedule and linked to its citation. The figures are not comparable to one another: some are flat minimums, some a percentage of job value, some charged per fixture, so what you pay depends on which schedule applies and on your job's valuation.
E-0 fee issuance cost per permit $20.00, E3.1 minimum fee $15.00, E-6.2 EXISTING RESIDENTIAL 1&2 FAMILY OCCUPANCIES $30.00 for 1 to 5 circuits and $45.00 for over 5 circuits providing 2 inspections, E6.3 service, feeder, or panel replacement $50.00, E6.4 in ground residential swimming pool $100.00, E6.5 residential low voltage $30.00, per the 2022 Fee Schedule, Electrical Permit and Inspection Fees Schedule. Work commencing before permit issuance is charged double fee. All fees exclude an administrative charge of $4.00 and a residential surcharge of $1.00, so $5.00 is added to the residential total, per the 2022 Fee Schedule.
