Rules for Properties in Unincorporated Areas
Properties located in unincorporated areas of Dickinson County fall under the jurisdiction of the DCCCC for mechanical permitting. Before beginning any HVAC work, property owners or contractors must file a mechanical permit application with the DCCCC. Key requirements and procedures include:
- Permit Requirement: Mechanical work must not commence until a permit has been issued.

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.
