Kentucky HVAC Building Codes and Legislation
The Commonwealth of Kentucky maintains a statewide, mandatory building code system, often referred to as a "mini/maxi" code, meaning local governments cannot adopt or enforce building codes that differ from the state-mandated standards. HVAC installations are governed by the Kentucky Building Code (KBC) for commercial structures and the Kentucky Residential Code (KRC) for one- and two-family dwellings and townhouses. These codes incorporate by reference various international and national standards, including the International Mechanical Code (IMC) and the International Energy Conservation Code (IECC), with specific Kentucky-based amendments.
Primary Regulatory Agency
The Kentucky Department of Housing, Buildings and Construction (DHBC) is the primary state agency responsible for setting and enforcing building and HVAC standards. Within the DHBC, the Division of Heating, Ventilation and Air Conditioning (HVAC) oversees the licensing of HVAC contractors and journeymen, as well as the administration of the statewide HVAC permitting and inspection program. This division ensures that all HVAC work complies with state statutes (KRS Chapter 198B) and administrative regulations (815 KAR Chapter 8).
