Permit Requirements for Chase, Michigan

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

HVAC Permit Requirements in Lake County, Michigan

In Lake County, Michigan, HVAC work generally requires a permit. Mechanical work cannot commence until a permit has been issued by the appropriate enforcing agency. Homeowners performing work on their own residence, as well as contractors, are responsible for securing the necessary permits.

County-Level Jurisdiction

Lake County has a Building Department that handles permit applications and enforcement throughout the county. For questions regarding county-issued permits, the Lake County Building Department can be contacted directly.

Unincorporated Areas

Lake County issues building permits specifically for properties located in the unincorporated areas of the county. If a property is within an incorporated city, that city's building department is responsible for permits, not the county.

For unincorporated areas, permit applications can be obtained from the Lake County Building Department office or downloaded from their website. Applications are accepted via USPS mail or in person; emails and faxes are not accepted.

The Lake County Building Department also handles mechanical permit applications. Mechanical work must conform to the Michigan Mechanical Code, and no work should be concealed until it has been inspected.

Specific forms for various projects in unincorporated Lake County, including some that may not require a full permit but rather a registration, are available. These include applications for air conditioner replacements, gazebo or screen room construction, and water heater replacements.

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.
