Do I need a permit for standby generator installation in Louisville?
Yes. In Kentucky, standby generator installation generally requires a permit, and Louisville is no exception.
Electrical work is different: state law requires an electrical permit and inspection for construction, alteration, or repair of any electrical system, issued by the local certified electrical inspector or, where none is available, by the Department of Housing, Buildings and Construction (KRS 227.480, 815 KAR 35:020). Fuel gas piping must meet the Kentucky Residential Code; confirm with the local office who permits and inspects the gas connection. Zoning setbacks or noise rules for generator placement are local.
Local detail for Louisville: Louisville and Jefferson County have a merged government, Louisville Metro, which issues building permits across the county. A few small cities inside Jefferson County may have their own rules, so confirm with Louisville Metro Construction Review.
