This conversion is considered a structural alteration and requires adherence to state building codes. The Wisconsin Uniform Dwelling Code (UDC) sets standards for construction, safety, and alterations, and specific design considerations for habitable rooms, such as minimum square footage for habitable rooms and bedrooms, as well as adequate light and ventilation, must be met.

Wisconsin Remodeler Legislation, Codes, and Guidelines

Wisconsin State Building Codes and Legislation for Remodelers and Residential Renovations

Wisconsin's building codes for remodelers and residential renovations are primarily governed by the Department of Safety and Professional Services (DSPS). The state adopts and modifies model codes from the International Code Council (ICC) to create its own administrative codes.

1. Specific State Statutes and Codes Adopted

For one- and two-family dwellings, the Uniform Dwelling Code (UDC), found in Wisconsin Administrative Code chapters SPS 320-325, applies. This code sets minimum standards for fire safety, structural strength, energy conservation, and general health and safety. The UDC is based on model codes but includes Wisconsin-specific adjustments.
For commercial and multi-family residential buildings, Wisconsin is transitioning to the 2021 International Building Code (IBC) standards, with additional state-specific adjustments. This updated code will take effect on September 1, 2025, and will be found in Wisconsin Administrative Code chapters SPS 361-366. Previously, the state used the 2015 editions of the model codes.
The International Existing Building Code (IEBC) is adopted and modified within Chapter SPS 366 of the Wisconsin Administrative Code, which covers the repair, alteration, change of occupancy, addition, or relocation of existing buildings.

2. Primary State Board or Agencies

The Department of Safety and Professional Services (DSPS) is the primary state agency responsible for setting and enforcing building codes and standards in Wisconsin.
Local municipalities also play a role in enforcing the UDC and may have their own specific permit requirements.

3. Classification of Remodels and Demolition Guidelines

Cosmetic vs. Structural Alterations: The UDC covers alterations to one- and two-family dwellings. While inspectors focus on code compliance, "cosmetic or non-code workmanship items will not normally be ordered corrected." However, deviations from approved plans may require revised submittals. The Wisconsin Home Improvement Practices Act (HIPA), found in Chapter ATCP 110 of the Administrative Code, defines "home improvement" broadly to include remodeling, altering, repairing, painting, or modernizing residential property, including additions. The definition of "remodel" in Wis. Stat. § 101.148 specifically means to alter or reconstruct a dwelling, and does not include maintenance or repair work.
When Demolition Guidelines Apply: Demolition activities require a demolition permit, which ensures compliance with local building codes and zoning laws. Specific requirements may include asbestos inspections for buildings constructed before the 1980s, utility clearances, and environmental inspections. In some municipalities, like Milwaukee, there are specific deconstruction ordinances for older structures to maximize salvageable materials. For demolition permits, all utility connections must be sealed and plugged, and a permit for boarding is not required if a demolition permit is obtained.
