Permit Requirements for Shelbyville, Michigan
For HVAC projects in Shelbyville, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Allegan County.
Authority Having Jurisdiction (AHJ)
Most jurisdictions require permits for HVAC work to ensure safety and code compliance. The governing body responsible for issuing these permits varies by specific location:
General HVAC Guidelines
Permits are usually required for new installations, structural modifications, or major repairs. While minor maintenance or cosmetic updates may be exempt, landowners should always verify local codes before work begins.

Allegan County HVAC Permit Jurisdiction
Allegan County does not maintain a centralized county-level Building and Safety Division that manages HVAC or mechanical permits for the entire county. Because Michigan is a "home rule" state, the responsibility for building codes, permits, and inspections rests with individual cities, villages, and townships. There is no single county office to contact for these permits; you must identify and contact the specific local jurisdiction where the property is located.
Rules for Properties in Unincorporated Areas
For properties located in unincorporated areas (townships), permit authority is handled at the local township level. Many townships in Allegan County contract with private inspection agencies or regional services to manage their building, mechanical, electrical, and plumbing permits. To determine the correct process for your property:
- Contact your local township hall directly to ask which agency or inspector handles mechanical/HVAC permits for their jurisdiction.
- Be prepared to provide the specific address of the project, as permit requirements and the responsible authority can vary significantly from one township to the next.
- Ensure you obtain the necessary permits before beginning any work, as starting without a permit often results in doubled fees or other penalties.
- Always verify that your contractor is properly licensed in the state of Michigan.

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.
