Knoxville's EV install story is tied to KUB and the Tennessee Valley Authority: KUB is the hometown utility, TVA is its wholesale power supplier, and KUB offers EV-specific rate options even though the old charger rebate is no longer shown as active. The city's 1974 median housing year also makes panel capacity checks important in established neighborhoods near downtown and the university.
Permit path
Permit required: Yes
KUB states that electrical permits for addresses inside Knoxville city limits must be purchased directly from the City of Knoxville, and the city's own EV charging page points residents to the Plans Review & Inspections guide under EV Permitting. For a home charger, the practical split is city permitting first, then KUB or Tennessee inspection coordination when service or meter work is involved.
Published permit fee: $35 electrical permit application fee; $75 for new electric service up to 150 amps, $80 for 151-200 amps, $100 for 200-400 amps; $15 for meter centers up to 200 amps; $5 for disconnects; $5 for a load center up to 100 amps plus $3 for each additional 100 amps or fraction

KUB's current EV page lists Time of Use and Electric Vehicle Charging rates for residential and commercial customers rather than an active residential charger rebate. Knoxville also offers 41 public Level 2 charging ports at 14 city sites for free public use, which is unusually concrete city-run EV infrastructure for a cost page.

Knox County is mapped to mixed-humid IECC zone 4A, so outdoor charger placement in Knoxville should account for rain, summer humidity, and freeze-thaw exposure at wall penetrations and conduit entries.

Wiring distance
Runs under 25 ft are cheapest. Longer runs or runs through finished walls add $200–$1,200+ depending on complexity.
Indoor vs. outdoor installation
Outdoor installs require a weatherproof NEMA 3R enclosure and conduit, adding $150–$400 to the total.
