- Space Conversions: Altering non-living spaces (such as finishing a basement, finishing an attic, or converting a garage) into habitable living areas.
- Structural Changes: Removing, adding, or modifying load-bearing walls, headers, or the roofline.
- Demolition: Extensive interior renovations or "gutting" a space often requires a specific demolition permit prior to or concurrent with the standard building permit.
- Systems Alterations: Rerouting plumbing pipes, adding new electrical circuits, or moving HVAC ductwork.

Michigan Remodeler Legislation, Codes, and Guidelines
Michigan Remodeling and Residential Renovation Building Codes
Michigan's building codes are primarily governed by the Stille-DeRossett-Hale Single State Construction Code Act (Public Act 230 of 1972). This act mandates statewide enforcement of construction codes to standardize building methods and requirements. The state adopts and amends model codes published by the International Code Council (ICC) and the National Fire Protection Association (NFPA).
1. Specific State Statutes and Codes Adopted
- Michigan has adopted the 2021 editions of the International Residential Code (IRC), International Building Code (IBC), International Mechanical Code (IMC), International Fuel Gas Code (IFGC), and International Energy Conservation Code (IECC), effective February 4, 2024.
- The Michigan Electrical Code is based on the National Electrical Code (NEC), with the 2023 NEC adopted.
- The state also utilizes the Michigan Rehabilitation Code for Existing Buildings, which addresses renovations and improvements to existing structures.
- Specific codes for residential renovations include the Michigan Residential Code (MRC), which is based on the International Residential Code (IRC) with state-specific amendments.
- The Michigan Rehabilitation Code for Existing Buildings is also relevant for renovations.
2. Primary State Board or Agencies
- The Michigan Department of Licensing and Regulatory Affairs (LARA), specifically the Bureau of Construction Codes (BCC), administers and enforces the statewide construction code.
- Local units of government (cities, villages, townships, and counties) also have the authority to enforce construction codes within their jurisdictions.
3. Classification of Remodels and Demolition Guidelines
- Cosmetic vs. Structural Alterations:
- Cosmetic renovations generally refer to aesthetic improvements that do not alter the structural integrity of the building. This can include painting, replacing fixtures, or updating finishes.
- Structural alterations involve modifying or reinforcing load-bearing components such as walls, foundations, floors, and roofs. These changes are more complex and often require professional design and engineering.
- Converting attics or basements to habitable living spaces typically involves structural changes and requires compliance with specific code requirements for egress, ceiling height, and fire safety.
- Any changes to load-bearing walls or structures require approval and must meet specific standards.
- Demolition Guidelines:
- A building permit is generally required for the demolition of a residential structure, especially for structures over 200 sq. ft., in-ground pools, or any portion of a house.
- Before demolition begins, an engineering survey must be conducted by a competent person to assess the structure's condition, potential impact on adjacent structures, and utility services.
- Demolition work must be performed safely, starting from the top and proceeding downward, with measures to protect adjacent properties and public access.
- Utility services must be disconnected and sealed by the relevant companies before demolition commences.
- Specific regulations apply to the removal of hazardous materials, such as asbestos, which may require specialized training and licensed contractors.
