Permit Requirements for Grosse Ile, Michigan
For HVAC projects in Grosse Ile, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Wayne 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:

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.

HVAC Permit Requirements in Wayne County, Michigan
In Wayne County, Michigan, HVAC permit requirements are primarily handled at the county level for certain types of work, particularly in unincorporated areas. For properties within unincorporated areas, Wayne County directly manages permits related to septic systems, soil erosion and sedimentation control, drainage or stormwater, and construction within county road rights-of-way.
While the state of Michigan requires a Mechanical Contractor License to perform HVAC work, the specifics of obtaining permits for HVAC installations or replacements often involve both county and local jurisdictions.
County-Level Jurisdiction
Wayne County's Department of Public Services and Environmental Health, along with its Permit Office, oversees various permits. This includes construction permits for work in public road rights-of-way or on county-owned property.
For HVAC work, a mechanical permit is generally required. The State of Michigan's Bureau of Construction Codes issues mechanical permits, and applications typically require details about the proposed work, contractor information, and adherence to the Michigan Mechanical Code.
Unincorporated Areas
In unincorporated areas of Wayne County, the county government is the direct authority for specific permits, including those related to on-site sewage systems (septic), soil erosion, drainage, and construction within county road rights-of-way.
When a local enforcing agency requires a building permit, a separate local permit must still be obtained, even if county permits are also necessary.

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.
