Lexington enforces Kentucky Building Code sprinkler requirements based on occupancy, height, and area, with Lexington Fire Department reviewing plans and inspecting installations under KRS 198B.
The Kentucky Building Code (815 KAR 7:120, adopted under KRS 198B) sets fire sprinkler thresholds based on International Building Code occupancy classifications. Most new commercial, multi-family residential over three stories, and assembly-occupancy buildings in Lexington require NFPA 13 or 13R sprinkler systems. Single-family homes are not required to sprinkler under Kentucky law, though voluntary NFPA 13D systems are permitted. LFD plan review and inspection occurs alongside Building Inspection's permit process. Annual inspections by licensed contractors are mandatory for installed systems. Sprinkler tampering is a misdemeanor under state law.
Building permit denial, occupancy permit holds, daily fines from LFUCG Building Inspection, and KRS 227 misdemeanor charges for tampering with required sprinklers.
