Do I need a permit for standby generator installation in Forest Hills?
Yes. In Tennessee, standby generator installation generally requires a permit, and Forest Hills 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. Forest Hills expressly lists back up generators, HVAC slabs, and equipment slabs as projects that require a City permit, so the City permits the generator placement and slab while Metro Nashville conducts the electrical and gas trade inspections. Generator placement must meet the City Zoning Ordinance setbacks and equipment clearances, which are reviewed during the City plan review. Tennessee requires a state license for most electrical and larger mechanical work, so confirm your installer holds the correct Tennessee classification.
