Garage conversion rules in Louisville, KY β sometimes called garage-to-ADU or accessory living unit conversions β govern permits, ceiling height, egress, and parking replacement.
Garage conversions to living space require a building permit in Louisville Metro. Converting a garage to an accessory apartment or additional living unit may require a Conditional Use Permit. All conversions must meet Kentucky Residential Code standards for insulation, egress, ventilation, and electrical work.
Under Louisville Metro building regulations (LMCO Β§ 150.001 adopting the Kentucky Residential Code), converting a garage to a living space requires a building permit from Codes & Regulations. If the conversion creates an accessory apartment or dwelling unit, a Conditional Use Permit may also be required through the Planning Commission. Alternatively, if the garage conversion qualifies as an ADU under LDC Β§ 4.3.27, it follows the ADU administrative approval process. All conversion work must meet the Kentucky Residential Code requirements for insulation (floor, ceiling, walls), egress windows, ventilation, heating, electrical wiring, and occupancy. The converted space must maintain adequate vehicle parking if required by the LDC for the applicable zone. Conversion projects in historic preservation districts require design review.
Unpermitted garage conversions: code enforcement citation, potential stop-work and restoration order. CUP violations (operating unauthorized dwelling units): zoning enforcement. Fine and court order for persistent violations.
