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

Dane County Remodeling and Renovation Permit Requirements

The Dane County Department of Planning and Development is responsible for reviewing development activities and administering ordinances in the unincorporated areas of Dane County.

1. Authority Having Jurisdiction: Dane County Building & Safety Division

The Dane County Department of Planning and Development, through its Zoning Division, acts as the Authority Having Jurisdiction for zoning permits in unincorporated areas. For building permits within incorporated towns, the specific town's building inspector or clerk should be consulted.

2. Rules for Properties in Unincorporated Areas

For properties in unincorporated areas of Dane County, a zoning permit from Dane County is generally required before obtaining a town building permit. This zoning permit is necessary for various projects, including building new structures, altering or adding to existing buildings, and structural repairs. Some towns may require town-specific permits in addition to the county zoning permit.

3. Permit Triggers for Demolition Work During a Remodel

Demolition work during a remodel may trigger the need for a demolition permit. In the City of Madison, a demolition permit is required for demolishing principal structures (houses, commercial buildings) and may be administratively approved for accessory structures (garages, sheds). A reuse and recycling plan may be required. For unincorporated areas, a wrecking permit is required prior to the demolition of any structures, and additional Dane County Zoning permits (such as erosion control or shoreland mitigation permits) may be necessary.

4. Permit Requirements for Altering Non-Living Spaces

Converting non-living spaces like garages, attics, or unfinished basements into habitable living areas typically requires permits. A zoning permit is generally needed for altering existing buildings. Specific requirements may include:

Zoning Permit: Required for altering a building. This involves submitting a site plan and floor plans for each level where work is being done.
Building Permit: While not explicitly detailed for non-living space conversions in the provided search results, building permits are generally required for alterations and additions that increase the physical dimensions of a building or involve significant structural changes. It is advisable to consult with the local building inspector.
Sanitary Permit: May be required if plumbing is involved in the conversion.
Change of Use Permit: A change of use permit is required if you are changing the use of an existing building on the property (e.g., barn to residence).

It's important to note that "no living spaces are allowed in accessory buildings" in some zoning districts, but an accessory dwelling unit (ADU) might be permitted under specific conditions, such as an apartment over a garage, which would likely require permits.

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.
