Knox County has no county-specific ordinance mandating or restricting residential EV charging stations. Installations follow the adopted electrical code and require an electrical permit through Knox County Codes Administration. Public charging is governed by state and utility standards.
The Knox County Zoning Ordinance and Code of Ordinances do not set a dedicated electric-vehicle-charging standard for homes. A home EV charger (Level 2, hardwired) is a standard electrical installation: it requires an electrical permit and inspection under the county's adopted National Electrical Code, obtained through Knox County Codes Administration and Enforcement. Commercial or public charging stations may be subject to site-plan and parking standards under zoning. Tennessee promotes EV infrastructure through state and TVA/utility programs. Inside Knoxville, the city's permitting applies. Always confirm current requirements with Codes Administration before installing.
Installing a hardwired EV charger without the required electrical permit and inspection can result in a stop-work order and correction requirements from Codes Administration.
