Michigan, Newaygo County HVAC Permit Regulations and County Ordinances for Unincorporated Areas

Newaygo County HVAC Permit Requirements

Newaygo County's Department of Building Safety & Permits handles building, electrical, mechanical, and plumbing permits for unincorporated areas of the county. If your property is located within an incorporated city, that city's building department is responsible for permits.

For HVAC work, permits are generally required before any construction, enlargement, alteration, or demolition begins. Ordinary repairs that do not affect the structural integrity of the building are typically exempt.

The county follows the Michigan Building Code and the Michigan Residential Code.

Rules for Properties in Unincorporated Areas

Newaygo County issues building permits for properties located in unincorporated areas. The process for obtaining a permit in these areas involves several steps:

Confirm zoning approval with the local township or city zoning official.
Obtain any necessary approvals for septic or sewer, well or water, soil erosion, driveway, floodplain, and energy code compliance.
Complete the county building permit application and submit it with duplicate working plans or blueprints.
Submit the application packet to the Newaygo County Department of Building Safety and Permits by mail or in person.
The county staff will review the plans and issue the permit.
Inspections (footing, foundation, rough, final, and trade inspections) will be scheduled as work progresses.
A Certificate of Occupancy must be obtained before occupying a new structure.

Permits are valid for one year as long as work is progressing and inspections are conducted. If no inspection is requested or conducted within 180 days, the permit will be closed and a new one will be required.

Work started before obtaining the proper permits may result in doubled permit fees, not to exceed $600.

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.
