Permit Requirements for Thompsonville, Michigan
For home remodeling and renovation projects in Thompsonville, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Benzie County.
Authority Having Jurisdiction (AHJ)
The governing body responsible for issuing building permits, reviewing plans, and conducting inspections varies depending on exactly where the property sits in Benzie County:
- Within City Limits: The Thompsonville Building Department typically oversees all Thompsonville building, trade, and safety permits.
- Unincorporated Areas: Properties located outside of official Thompsonville boundaries are generally governed by the Benzie County Building & Safety Division.
Common Remodeling Permit Triggers
Remodeling is a broad category, and permit requirements depend heavily on the scope of your work. While cosmetic updates—such as painting, installing new flooring, or replacing like-for-like kitchen cabinets—generally do not require approval in Michigan, you will almost certainly need a permit for the following:
- 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, Benzie County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas
Benzie County Building & Safety Division
The Benzie County Building Safety and Code Enforcement Department is responsible for administering and enforcing state building codes within Benzie County and Springdale Township in Manistee County. This includes inspections for new construction, existing buildings, accessory structures, remodels, electrical, mechanical, plumbing, and demolition work. The department utilizes BS&A computer programs for permit processing and code enforcement, integrating with other county departments for up-to-date parcel information. They employ a team of contract staff and inspectors to ensure compliance with construction industry minimum requirements and public safety. The Building Official is appointed by the Board of Commissioners or Township Boards to oversee code enforcement and act as an inspector and plan reviewer.
Properties in Unincorporated Areas
Benzie County issues building permits exclusively for properties located in unincorporated areas of the county. If a property is situated within an incorporated city, that city's building department is the authority for permit issuance, not Benzie County.
Permit Triggers for Demolition Work During a Remodel
Demolition permits are issued by the Benzie County Building Department. Specific requirements for a demolition permit include submitting a lot diagram or plot plan, proof of ownership, the property's tax ID number, and documentation of utility disconnections from the utility companies servicing the structure. Blueprints and drawings with sufficient detail for plan review are also required, including wall sections, floor plans, and details of room dimensions, window, door, and stair openings. For structures with pre-manufactured members, a sealed diagram from the manufacturer is necessary.
Permit Requirements for Converting Non-Living Spaces
Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas generally requires a building permit. Depending on the scope of work, additional electrical, plumbing, or mechanical permits may also be necessary. It is recommended to consult with the Building Safety and Code Enforcement Department early in the planning process to discuss zoning and building requirements.
Garages, Attics, and Unfinished Basements
- Habitable Space Standards: To be considered habitable, spaces typically need to meet minimum ceiling height requirements (often at least 6'8" in basements and 7 feet for at least half the ceiling in attics), minimum floor area (e.g., 70 square feet), and specific dimensions.
- Egress Requirements: Habitable spaces, especially sleeping rooms in basements, usually require at least one egress window or exterior door for emergency escape. Attics often need two means of egress, including a code-compliant staircase and an egress window.
- Stairway Access: New stairways must meet current code. Existing stairways to new living spaces must be at least 30 inches wide with a minimum headroom of 6'2". Landings are required at the top and bottom of stairs.
- Electrical and Plumbing: Converting these spaces often involves extending or installing new electrical wiring and plumbing, which will require separate permits.
- Parking Requirements (Garages): If converting a garage, you may need to demonstrate how a required on-site parking space will be provided.
- Structural Considerations: Changes to structural components, such as load-bearing walls or roof structures, will require permits and potentially a structural engineering review.
- Insulation: Converted spaces must meet energy efficiency standards, including adequate insulation values.

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