Wisconsin, Fond Du Lac County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas

Fond du Lac County, Wisconsin Remodeling and Renovation Permit Requirements

In Fond du Lac County, Wisconsin, permit requirements for remodeling and renovation projects are primarily handled at the local level, with municipalities and the county sharing jurisdiction depending on the specific location and nature of the work. The Wisconsin Uniform Dwelling Code (UDC) provides a statewide baseline for construction standards.

1. Authority Having Jurisdiction (AHJ)

The primary AHJ for building permits in Fond du Lac County is typically the local municipality (city or town) where the property is located. For unincorporated areas, Fond du Lac County's departments, such as the Highway Department or Code Enforcement Office, may have permitting authority for specific issues like land use, floodplain zoning, or private water systems. The City of Fond du Lac has its own Building Inspection Division, which adopts and enforces state codes.

2. Rules for Properties in Unincorporated Areas

For properties in unincorporated areas of Fond du Lac County, the County's Code Enforcement Office and Highway Department are key points of contact. They administer various ordinances, including Floodplain Zoning, Private Onsite Wastewater Treatment System (POWTS) Ordinance, and Shoreland Zoning Ordinance. A Land Use Permit may be required before starting a project in these areas.

3. Permit Triggers for Demolition Work

Demolition work, even as part of a remodel, generally requires a permit. This is to ensure compliance with local building codes and zoning laws. Before demolition, it's crucial to obtain utility clearances and, depending on the building's age, an asbestos inspection certificate. The City of Fond du Lac explicitly lists demolition of existing structures as an activity requiring a permit.

4. Permit Requirements for 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 such conversions involve changes to the structure, electrical, and plumbing systems, and alter the building's occupancy classification.

Definitions and Requirements:

Habitable Room: A habitable room is defined as any room used for sleeping, living, or dining purposes. It excludes spaces like closets, kitchens, pantries, bathrooms, service rooms, hallways, laundries, storage spaces, cellars, and utility rooms.
Minimum Standards: Habitable rooms must meet specific standards for ceiling height (at least 7 feet, with exceptions for sloping ceilings), window area (at least 8% of floor area), and egress.
Garages: Converting a garage into living space often requires meeting parking space requirements, as some jurisdictions may not permit conversion if it eliminates necessary covered parking. The construction or alteration of garages is also subject to specific size and height regulations, and must often complement the main dwelling's architectural design.
Basements and Attics: Finished rooms in basements or below grade, intended for year-round occupancy, are considered habitable rooms and must comply with building planning standards. Specific requirements apply to basements and ground floors used for sleeping, which necessitate at least two exits.

It is always recommended to contact the relevant local building department or the Fond du Lac County Building and Zoning Inspector for specific guidance on your project, as requirements can vary.

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.
