Clinton County Building Department Jurisdiction
In Clinton County, Michigan, the Building Department is responsible for administering and enforcing the State of Michigan Building Codes, which includes the issuance of mechanical (HVAC) permits. The department provides these services for 13 general law townships within the county, as well as for various cities and villages that utilize the county's building services. It is important to verify your specific jurisdiction, as some municipalities may handle their own permitting.
Rules for Properties in Unincorporated Areas
For properties located in unincorporated areas of Clinton County, the Clinton County Building Department serves as the primary authority for mechanical permits. If you are planning HVAC work—such as installing or replacing a furnace, air conditioning unit, or other mechanical equipment—you must obtain a mechanical permit from the county before beginning the work. The process requires submitting a completed mechanical permit application, which is available through the county's Forms Center. All mechanical work must be performed in accordance with the State Mechanical Code and is subject to inspection to ensure compliance with safety standards. Work should not be enclosed, covered, or put into operation until it has been inspected and approved by the mechanical inspector.

Michigan Hvac Legislation, Codes, and Guidelines
Michigan HVAC Building Codes and Legislation
In Michigan, the regulation of heating, ventilation, and air conditioning (HVAC) systems is governed by a framework of state-adopted codes. The primary enabling legislation is the Stille-DeRossett-Hale Single State Construction Code Act (Public Act 230 of 1972), which authorizes the state to establish uniform construction standards.
For mechanical systems, Michigan has adopted the 2021 Michigan Mechanical Code, which is based on the 2021 International Mechanical Code (IMC) with specific Michigan amendments to address local climate, safety, and enforcement needs. For residential projects (one- and two-family dwellings), HVAC requirements are primarily contained within the Michigan Residential Code, which is based on the 2021 International Residential Code (IRC) with state-specific amendments.
These codes establish the minimum requirements for the design, installation, maintenance, alteration, and inspection of mechanical systems. Compliance with these standards is mandatory, and work typically requires a permit from the local Authority Having Jurisdiction (AHJ) and must be performed by a licensed mechanical contractor.
Primary State Agency
The Michigan Department of Licensing and Regulatory Affairs (LARA), specifically through its Bureau of Construction Codes (BCC), is the primary agency responsible for the adoption, administration, and enforcement of the statewide construction codes. The Bureau oversees the development of these codes, manages contractor licensing, and provides guidance on code compliance and permitting processes across the state.
