Kentucky Tiny House Zoning Laws Overview
Kentucky's approach to tiny house zoning reflects its diverse geography—from the Appalachian Mountains in the east to the rolling bluegrass pastures of central Kentucky and the flatter western regions—with regulations varying substantially across its 120 counties. The state has adopted Appendix Q of the International Residential Code, which provides guidelines for tiny homes on permanent foundations, but implementation differs by location. Counties and municipalities set their own rules for accessory dwelling units (ADUs), with Jefferson County (Louisville) and Fayette County (Lexington) being among the most progressive in accommodating tiny houses through updated ADU ordinances. Rural counties often have more flexibility with fewer zoning restrictions, while urban areas typically impose stricter requirements. Tiny houses on permanent foundations must comply with the Kentucky Building Code, including minimum ceiling heights (6'8" in living areas, 6'4" in kitchens and bathrooms) and safety standards. Tiny houses on wheels (THOWs) face significant challenges as they're generally classified as recreational vehicles subject to occupancy time limits and restricted locations. The absence of statewide tiny house laws means prospective owners must thoroughly research local ordinances before purchasing land or beginning construction. Water and septic requirements, minimum lot sizes, and flood plain considerations add further complexity to placement decisions, making consultation with county planning and zoning departments essential before committing to a tiny house project in the Bluegrass State.
Kentucky has adopted Appendix Q of the IRC, but tiny house regulations vary widely across 120 counties, with THOWs generally restricted as RVs.
