HVAC Permit Requirements in Bourbon County, Kentucky
In Bourbon County, Kentucky, HVAC permitting is handled at the state level rather than through a local county building department. While the Bourbon County Joint Planning Office manages general building and electrical permits for both incorporated and unincorporated areas, HVAC permits must be obtained through the Kentucky Department of Housing, Buildings and Construction (DHBC), Division of HVAC.
Rules for Properties in Unincorporated Areas
The requirements for HVAC permits apply consistently across the state, including for properties located in unincorporated areas of Bourbon County. Key regulations include:
- Permit Requirement: A state HVAC permit is required for all new construction, construction additions that include an additional HVAC system, and existing buildings where the first HVAC system is being installed.
- Licensed Contractors: Permits must generally be obtained by a Kentucky-licensed Master HVAC contractor.
- Homeowner Exception: A homeowner may apply for a permit to install an HVAC system in their own legal residence, provided they meet specific state requirements, including filing an affidavit and providing proof of adequate system sizing.
- Inspections: All permitted HVAC work is subject to inspection by the state HVAC inspector assigned to the region.
- Local Coordination: Although the permit is through the state, property owners and contractors should still coordinate with the Bourbon County Joint Planning Office regarding overall building permit requirements, as the HVAC permit is often a component of the broader construction approval process.

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).
