Permit Requirements for Peck, Michigan

For HVAC projects in Peck, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Sanilac 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.

Because Peck is located within Sanilac County, the following broader county regulations may also apply to your project:

Sanilac County HVAC Permit Requirements

In Sanilac County, Michigan, HVAC work generally requires a permit. The Sanilac County Building Department handles permits for building, electrical, plumbing, and mechanical work. For properties in unincorporated areas, the county's Building Department is the primary point of contact for these permits. It is mandatory to obtain the required permits before starting any HVAC installation, alteration, repair, or replacement.

Some exceptions to permit requirements exist, primarily for portable appliances with low BTU inputs (less than 30,000 BTU/hr), portable ventilation or cooling units, and minor replacement parts that do not compromise safety or approval. However, it is crucial to verify specific exemptions with the Sanilac County Building Department, as rules can change.

For work in areas with local municipal jurisdiction (e.g., cities or townships), you may need to coordinate with both the local zoning or land use administrator and the Sanilac County Building Department. For instance, in Croswell, city zoning approval is a separate step before applying for county building, electrical, plumbing, and mechanical permits. Similarly, Lexington and Sanilac Townships require local land use permits that must accompany the county building permit application.

The State of Michigan also has statewide regulations. Mechanical work must comply with the Michigan Mechanical Code. Permits are typically valid as long as work is progressing, but they can become invalid if work is not commenced within 180 days of issuance or is suspended for 180 days. Re-opening a closed permit usually incurs a fee.

For unincorporated areas, the Sanilac County Building Department is responsible for enforcing building codes. If a specific township or city has its own building department, you may need to apply there first for local permits, and then with the county for the trade permits.

The following statewide building codes and regulations apply universally to all jurisdictions within Michigan:

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.
