Kentucky, Clark County HVAC Permit Regulations and County Ordinances for Unincorporated Areas
HVAC Permit Requirements in Clark County, Kentucky
In Clark County, Kentucky, the regulation and permitting of HVAC systems are managed at the state level through the Kentucky Department of Housing, Buildings and Construction (DHBC), Division of HVAC. Unlike some other counties in Kentucky that have established their own local HVAC inspection programs, Clark County utilizes the state-level system for HVAC permitting and inspections.
Rules for Properties in Unincorporated Areas
For properties located in unincorporated areas of Clark County, as well as within incorporated areas that do not have their own local HVAC program, you must coordinate with the state-assigned HVAC inspector. Because Kentucky enforces a uniform, statewide building code, HVAC work—including new installations, replacements, and alterations—requires a permit. These permits must generally be obtained by a licensed master HVAC contractor, though specific provisions exist for homeowners to apply for permits on their own primary residences. Before beginning any HVAC work, it is essential to contact the state inspector assigned to Clark County to confirm the specific application process, required documentation (such as load calculations and duct designs), and inspection scheduling procedures.

Kentucky Hvac Legislation, Codes, and Guidelines
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).
