Full Breakdown

Kentucky adopted the Kentucky Residential Code under KRS Chapter 198B, administered by the Department of Housing, Buildings and Construction. The state code is mandatory and uniform statewide; local governments cannot adopt weaker standards. The Kentucky Residential Code incorporates International Residential Code provisions including tiny house standards in Appendix Q for dwellings 400 square feet or less, addressing ceiling heights, lofts, ladders, and emergency escape openings. Tiny homes on permanent foundations qualify as dwellings; those on wheels are typically classified as recreational vehicles under KRS 227.550 manufactured housing rules. Local zoning controls siting and minimum dwelling sizes but cannot lower construction standards.

Violations & Penalties

Construction without permits or below code minimums triggers stop-work orders, daily fines, and required corrections before certificate of occupancy issues.
