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

Brown County Building & Safety Division (Authority Having Jurisdiction)

Brown County's Planning and Land Services (PALS) Department, specifically the Zoning Division, is involved in issuing permits for shoreland, flood plain, and wetland use, as well as sanitary permits for onsite wastewater treatment systems. However, for general building permits in unincorporated areas of Brown County, the authority often lies with the local town's building inspector or zoning administrator, rather than a single countywide department.

Rules for Properties in Unincorporated Areas

In unincorporated areas of Brown County, the county's Zoning Division regulates shoreland, wetland, and floodplain areas. For other building and zoning requirements, property owners must contact their specific local town.

Permit Triggers for Demolition Work During a Remodel

Demolition work during a remodel generally requires a permit. In Wisconsin, demolition projects that meet certain criteria, particularly those involving potential asbestos, require notification to the Department of Natural Resources (DNR) at least 10 working days before the project begins. While demolishing a single-family home may not always require DNR notification, it is recommended to follow precautionary steps. Local ordinances also often require a specific demolition permit for any demolition of existing buildings.

Permit Requirements for Altering or 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 changes to the building's use, structure, and safety systems, necessitating compliance with state and local building codes.

Garages: Converting a garage into a living space often requires permits for structural modifications, electrical work, plumbing, and zoning compliance.
Attics: Attic renovations that create habitable space, such as bedrooms or offices, generally require a permit. This includes meeting specific codes for ceiling height, room dimensions, egress (emergency exits), and potentially staircase requirements.
Unfinished Basements: Transforming an unfinished basement into living space requires a permit and adherence to building codes related to natural light, ventilation, ceiling height, egress, insulation, and the installation of safety devices like smoke and carbon monoxide detectors. Plans detailing proposed work, room usage, and structural elements are typically required.

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.
