Shiawassee County HVAC Permit Requirements
In Shiawassee County, Michigan, separate permits are required for heating, ventilating, and air conditioning (HVAC) work. The Shiawassee County Community Development Department handles building and trade inspections, including the review and issuance of permits for new construction and improvements. This department enforces the provisions of the State Construction Code Act.

Key requirements and considerations for HVAC permits include:

- Permit fees vary based on the type and scope of the HVAC work. For example, fees are listed for air conditioning units, air handlers, and various types of heaters.
- Work must commence within 180 days of permit issuance, and if work is suspended or abandoned for 180 days, the permit becomes void.
- All work must be installed in accordance with the Michigan State Building Code and will not be covered, enclosed, or put into service until inspected and approved by a Shiawassee County Inspector.
- Homeowners performing work on their own single-family dwelling may be able to install the work themselves, provided they occupy the home, but must still adhere to all codes and obtain necessary inspections.
- Contractors must be registered with the Building Department.
- Plan review may be required for certain projects, such as homes with over 400 amp service or those exceeding 3,500 square feet.

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.
