Permit Requirements for Downing, Wisconsin
For home remodeling and renovation projects in Downing, determining the correct permitting authority depends on whether the project site is located within the incorporated city limits or in an unincorporated area of Dunn County.
Authority Having Jurisdiction (AHJ)
The governing body responsible for issuing building permits, reviewing plans, and conducting inspections varies depending on exactly where the property sits in Dunn County:
- Within City Limits: The Downing Building Department typically oversees all Downing building, trade, and safety permits.
- Unincorporated Areas: Properties located outside of official Downing boundaries are generally governed by the Dunn County Building & Safety Division.
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 Wisconsin, 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.

Dunn County, Wisconsin Remodeling and Renovation Permit Requirements
Dunn County, Wisconsin, has specific requirements for remodeling and renovation permits, particularly for properties located in unincorporated areas. The authority for issuing building permits generally lies with the local town or municipality, though Dunn County may be involved in zoning and land use aspects.
1. Authority Having Jurisdiction (AHJ)
For properties within unincorporated areas of Dunn County, the local town's building inspector or clerk typically serves as the Authority Having Jurisdiction (AHJ) for building permits. Some towns, like the Town of Dunn, adopt the Wisconsin Uniform Dwelling Code (UDC) and require permits for alterations, additions, or structural changes. If a property is within an incorporated city, that city's building department handles permit issuance, not Dunn County.
2. Rules for Properties in Unincorporated Areas
In unincorporated areas of Dunn County, building permits are generally required for new construction, additions, and significant remodeling projects. The specific requirements and fees are determined by the local town. For instance, the Town of Sherman requires a building permit for new homes, remodels, and additions, with varying costs based on the project's value. The Town of Stanton's ordinance requires a permit for alterations valued over $3,000 in a 12-month period, or for any structural or major mechanical system changes. Some towns, such as the Town of Dunn, may not require permits for minor repairs like replacing windows of the same size, roofing or siding repairs under 49% of the structure, or routine HVAC and plumbing repairs.
3. Permit Triggers for Demolition Work During a Remodel
A wrecking or demolition permit is required prior to the demolition of any structures in Wisconsin. This permit ensures compliance with local building codes and zoning laws. In some cases, additional permits from Dane County, such as erosion control or shoreland zoning permits, may be necessary before a town wrecking permit can be issued. Proper disconnection of utilities and sealing of service connections are also required before demolition can commence.
4. Permit Requirements for Altering or Converting Non-Living Spaces
Converting non-living spaces like garages, attics, or unfinished basements into habitable living areas typically requires a building permit. This is because such conversions change the use of the space and necessitate compliance with building codes related to safety, ventilation, and occupancy.
- Garages: Converting a garage into a living space often requires permits for electrical, plumbing, and structural modifications. Zoning permits may also be necessary to ensure the property is zoned for residential use and meets setback and lot coverage requirements.
- Attics: Creating habitable space in an attic generally requires a permit. This includes ensuring minimum ceiling heights (often 7 feet for at least 50% of the floor area), adequate room dimensions, proper insulation, and code-compliant stair access and egress (emergency exits).
- Unfinished Basements: Turning an unfinished basement into living space requires compliance with building codes for ventilation, safety equipment, and egress. Dunn County has also approved a plan for Accessory Dwelling Units (ADUs), which can include converted basement apartments, with specific conditions regarding size, wastewater, and deed restrictions.

The following statewide building codes and regulations apply universally to all jurisdictions within Wisconsin:
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.
