Montgomery County, Kentucky HVAC Permit Requirements
In Montgomery County, Kentucky, HVAC permit requirements are primarily handled at the county level for unincorporated areas. Commercial projects may be routed to the state building inspector. Kentucky law mandates that any work altering structures or mechanical systems requires a permit from the county inspector. The building code enforced is the 2015 International Residential Code with 2018 Kentucky Residential Code amendments.
For properties in unincorporated areas of Montgomery County, the County Building Inspector's office is the primary point of contact for permit applications. It is recommended to call the building inspector to confirm jurisdiction for your specific project, as commercial work may be referred to the state. After jurisdiction is confirmed, you will submit the application, drawings, site plan, and other required documentation. Inspections, such as footing, framing, and final inspections, are scheduled through the same office after the permit is issued.
Statewide, Kentucky requires HVAC installation permits for new installations, construction additions with new HVAC systems, and for existing buildings receiving their first HVAC system. Permits are generally issued only to licensed master HVAC contractors, though homeowners may be able to obtain permits for work on their own residence under specific conditions. Replacement of a single component of an HVAC system typically does not require a permit, but replacement of major components like furnaces or heat pumps may.
Fees for HVAC permits vary based on the type of installation (one- or two-family dwelling, multi-family, or commercial) and the number of systems. For one- and two-family dwellings, the fee is typically $75 for the first system and $50 for each additional system. Multi-family dwellings have a fee of $75 for the first system and $25 for each additional system. Commercial installations are typically based on the total dollar value of the installation.
Each permit usually includes three inspections. Additional inspections beyond the initial three will incur a fee of $50 per inspection. Permits become void if work ceases for more than twelve months.

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).
