Hot tubs in Jefferson County require an electrical permit for the 240V circuit under 2018 Kentucky Residential Code. Barrier requirements met by ASTM F1346 safety cover. Setbacks follow LMCO Land Development Code.
Hot tub and spa installations in Louisville Metro require an electrical permit from Louisville Metro Codes and Regulations for the required 240V (typically 50-amp) GFCI-protected circuit under the 2018 Kentucky Residential Code (based on 2017 NEC). A locking safety cover meeting ASTM F1346 standards satisfies the barrier requirement under 2018 KRC Appendix G — no perimeter fence needed if the cover is in place when unattended. Setbacks from property lines follow LMCO Land Development Code (typically 5 feet side/rear in R-4 and R-5 zones); closer placement may require variance through Board of Zoning Adjustment. Structural load considerations apply for deck or second-story installations (filled spa weighs 3,000-5,000 pounds). MSD stormwater rules apply for drain water — discharge to sanitary sewer preferred; discharge onto neighboring property prohibited. Indoor spas require ventilation per International Mechanical Code.
Unpermitted electrical work: stop-work order, double permit fees, potential disconnect. Non-compliant safety cover: immediate correction and possible civil liability. Drainage to storm sewer or neighboring property: MSD enforcement and civil action.
