Building permits, zoning and land rules in Marinette County, Wisconsin

Yes. A new one- or two-family dwelling in Marinette County needs a Wisconsin Uniform Dwelling Code building permit, including a stick-built, modular or manufactured-home installation¹. A municipality with delegated authority issues and inspects that building permit; otherwise the application goes to the Wisconsin Department of Safety and Professional Services¹. County zoning approval remains separate for covered unincorporated land, and Marinette County continues to regulate onsite wastewater systems countywide^2,3. An owner who occupies or will occupy the dwelling may apply for construction and erosion-control permits without Dwelling Contractor Certification, but the owner-builder allowance does not waive the building permit or code requirements⁴. Marinette County zoning-permit fees are set by the County Board, but the cited ordinance does not state the amount².

The building-permit issuer depends on the parcel's municipality: contact a municipality that has delegated Uniform Dwelling Code authority, but submit through Wisconsin DSPS when the municipality lacks that authority¹. Ask the town, village or city clerk whether the municipality uses the state eSLA system and who performs building inspections⁴. Municipal building-permit authority does not move county zoning or septic work: Marinette County Land Information handles county zoning, sanitation, shoreland and floodplain questions at 715-732-7541 or at the Resource Center, 1925 Ella Court in Marinette^2,3,8. The county office also links to property, sanitary, permit and GIS data⁸.

Yes, within defined territory. Marinette County Chapter 17 divides the listed unincorporated town territories into Forestry, Recreation and Unrestricted districts; incorporated villages and cities are outside that county chapter². A district called Unrestricted is still a mapped county zoning district, and buildings and uses must conform to its district rules². Most construction, enlargement, alteration, relocation or changes in use require county zoning approval in covered territory⁹. Give Marinette County Land Information the parcel number and confirm jurisdiction, district, use and setbacks before designing⁸. In applicable shoreland areas, structures are generally set back 75 feet from the ordinary high water mark; a qualifying open-sided structure no larger than 200 square feet may use a 35-foot setback when the vegetation condition is met⁹.

Marinette County regulates the location, construction, installation, alteration, maintenance and use of onsite wastewater systems throughout the county, including addresses where a city or village handles building permits or zoning³. Contact County Land Information before fixing the house location, because a building permit for a new dwelling using private onsite wastewater cannot issue until the sanitary permit has issued^7,8. The county materials do not confirm exactly when each septic permit form is required, so ask the Zoning/Sanitary Division which application fits the parcel⁸. Only 12.6% of county soils are mapped without severe limitations for a conventional septic drain field, so make an acceptable site evaluation a purchase condition¹⁰. All county septic-system owners must join the maintenance program, and septic tanks should be inspected or pumped every 3 years¹¹.

We could not confirm a Marinette County rule that generally allows long-term RV residence on private land, so ask the county Zoning/Sanitary Division about the parcel, duration and wastewater plan before moving in⁸. The located RV rule governs designated county park campsites and does not resolve private-land occupancy⁵. We also could not confirm a countywide tiny-home occupancy rule or minimum dwelling size; ask which zoning district and dwelling classification apply⁸. A tiny home used as a new dwelling may still fall under the state building-permit system, and manufactured-home installations expressly require a Uniform Dwelling Code building permit¹. Any building with plumbing fixtures outside public sewer service needs a suitable way to treat, recycle, disperse or hold wastewater⁶.

1. Confirm whether the parcel is in a town, village or city and ask the municipal clerk whether the municipality or Wisconsin DSPS issues its Uniform Dwelling Code building permit¹.
2. Give Marinette County Land Information the parcel number and confirm whether county zoning applies, then check the mapped district, proposed use, shoreland setbacks and floodplain constraints^2,8.
3. If the home will use private septic, establish a workable system and obtain the applicable county sanitation approval before the building permit^3,7.
4. Submit the building-permit application, contractor details, plans, project information and fee through the municipal or DSPS route that applies¹.
5. Begin after approval, then notify the inspector named on the building permit for footings, foundation, rough work, insulation and final inspections¹.
6. Take occupancy only after the final inspection finds no major health or safety violations; some municipalities also issue an occupancy permit⁷.

Start with jurisdiction and zoning: Chapter 17 covers the listed unincorporated town territories, while incorporated villages and cities follow other zoning rules². Check wastewater feasibility early because just 12.6% of mapped county soils avoid severe conventional drain-field limits¹⁰. For waterfront land, locate the ordinary high water mark because structures are generally set back 75 feet, with narrower exceptions for qualifying structures⁹. Height limits of 32 or 35 feet apply to certain nonconforming structures, not every building countywide⁹. Development in a floodway faces strong limits, including prohibitions on new structures, wells and sewage systems¹². A driveway connecting to a state highway needs a WisDOT connection permit¹³. Wisconsin requires advance notice before construction of most new private wells, but we could not confirm an additional Marinette County well permit¹⁴.
