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.

Hillsdale County, Michigan: Remodeling and Renovation Permit Requirements
This document outlines the permit requirements for remodeling and renovation projects in Hillsdale County, Michigan, with a focus on unincorporated areas and specific types of work.
1. Authority Having Jurisdiction: Hillsdale County Building Inspection
The Hillsdale County Building Inspection Office is the primary authority for issuing building, electrical, plumbing, and mechanical permits within the county. For projects within incorporated cities, such as the City of Hillsdale, local zoning approvals may also be required before applying for county permits.
2. Properties in Unincorporated Areas
For properties located in unincorporated areas of Hillsdale County, the Hillsdale County Building Inspection Office serves as the Authority Having Jurisdiction (AHJ) for building, electrical, plumbing, and mechanical permits. It is advisable to contact the county directly for specific requirements pertaining to unincorporated areas, as local ordinances may vary.
3. Permit Triggers for Demolition Work During a Remodel
A building permit is generally required for demolition work. Specifically, a permit is required for the demolition of residential structures over 200 square feet, in-ground pools, or any portion of a house. Demolition of structures under 200 square feet may not require a building permit but must comply with specific site preparation and debris removal requirements.
4. Permit Requirements for Converting Non-Living Spaces
Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas typically requires a building permit. This is because these conversions involve structural, electrical, and plumbing modifications to meet safety and occupancy codes.
- Garages: Converting a garage into living space requires a building permit. This includes any associated plumbing, electrical, or mechanical work. The new living space must comply with current residential and energy codes. Additionally, alternative off-street parking may be required if garage parking is eliminated.
- Attics: Renovating an attic to create habitable space generally requires a building permit. This often involves meeting specific building codes for safety and occupancy, such as minimum ceiling height (often at least 7 feet for 50% of the space), minimum room dimensions, and adequate egress (emergency exit), which typically includes a full-size staircase and/or an egress window.
- Unfinished Basements: Finishing an unfinished basement to create habitable space necessitates a building permit. This includes structural changes, electrical modifications, plumbing installations (e.g., bathrooms, wet bars), and HVAC system changes. Requirements often include minimum ceiling heights (7 feet), proper egress windows for bedrooms, and adequate insulation.
In all cases of converting non-living spaces, detailed building plans illustrating the proposed work, including floor plans, window and door locations, and utility systems, are typically required for permit applications.

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.
