Do I need a permit for standby generator installation in Goodlettsville?
Yes. In Tennessee, standby generator installation generally requires a permit, and Goodlettsville is no exception.
A permanently installed standby generator with an automatic transfer switch requires an electrical permit, and a gas or LP fuel connection typically requires a separate gas/plumbing permit and inspection. Location clearances from windows, doors, and property lines are enforced; confirm submittal requirements with your local codes department before installation. A permanently installed standby generator ties into the electrical service and typically a gas or propane line, and on the Davidson County side of Goodlettsville those electrical and gas/mechanical permits come from the Metro Nashville Codes Department. Confirm generator placement against Goodlettsville zoning setbacks and clearances with the Codes and Building Safety office at 615-851-3741, since the city enforces the zoning ordinance. The City of Goodlettsville will not issue final approval until the Metro Nashville permits have passed their final inspection, so coordinate both offices.
