Wisconsin, Florence County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas

Florence County Building & Safety Division

Florence County's Building Inspector administers and enforces building codes, including the Wisconsin Uniform Dwelling Code (UDC) for one- and two-family dwellings built since June 1, 1980. The county enforces these regulations in municipalities that do not have their own UDC enforcement program. The Building Inspector must be certified by the Wisconsin Department of Safety and Professional Services (DSPS) in the relevant categories.

Rules for Properties in Unincorporated Areas

The Florence County Zoning Ordinance applies to all unincorporated areas of the county. This ordinance aims to promote public health, safety, and general welfare by establishing reasonable standards for buildings and structures, regulating land use, and conserving natural resources. Permits are generally required for construction or alteration of buildings in these areas, unless specifically exempted by law.

Permit Triggers for Demolition Work During a Remodel

A demolition permit is required for the demolition, removal, or destruction of an existing structure. While minor interior remodeling may not require a demolition permit, any work involving the removal of a structure or significant structural demolition will likely trigger the need for a permit. It is advisable to contact the Florence County Building Department for specific guidance on demolition permit requirements related to your remodel project.

Permit Requirements for Converting Non-Living Spaces

Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas requires a building permit. Depending on the scope of work, additional electrical, plumbing, or mechanical permits may also be necessary. Existing conditions in these spaces, such as ceiling heights, window sizes, and insulation, must meet current building code requirements for finished living spaces. For example, habitable rooms generally need a minimum of 70 square feet of floor area, and sleeping rooms require at least 70 square feet for one occupant. Basements converted to living space must have a ceiling height of at least 6'8", and all sleeping rooms in basements, as well as the basement itself, must have at least one egress window or exterior door for emergency escape. Egress windows must have a sill height of 44 inches or less.

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.
