Do I need a permit for electrical panel or service upgrade in Louisville?
Yes. In Kentucky, electrical panel or service upgrade 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). The only electrical exemptions in the Kentucky Residential Code (Section R105.2) are minor items such as replacing a breaker of the required capacity in the same location; a panel replacement or upgrade is not exempt. A homeowner may do electrical work on their own premises without a license but still needs the permit and inspection (KRS 227.480(2)(a), KRS 227A.030(3)).
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.
