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

Yes. Every new one- or two-family dwelling in Richland County needs a Uniform Dwelling Code building permit; additions also need one in certain townships¹. Wisconsin's UDC applies to new one- and two-family dwellings, including stick-built, modular and manufactured-home installations⁷. The UDC is enforced in all Wisconsin municipalities⁸. Construction may begin only after plans are approved and the building permit is issued and posted⁹.

The UDC building permit is separate from county land-use and sanitary permits⁷. Contact the inspector serving the parcel for the UDC permit, and use the Zoning & Sanitation Department for applicable county approvals¹. Permit requirements for alterations and additions vary by municipality, so confirm the scope before ordering materials⁹.

For rural Richland County building permits, the county directs applicants to the UDC inspector serving the project’s township; the Zoning & Sanitation Department handles county land-use review¹. The department can be reached at 608-647-2447 or zoning@co.richland.wi.us at 181 W. Seminary Street, Richland Center, WI 53581². Where local UDC authority is not approved, the DSPS-appointed inspector applies¹⁰.

UDC inspections cover footings, foundation and reinforcement, rough construction, insulation and the final inspection; notify the inspector identified on the building permit before covering work^7,9. An owner who currently occupies or will occupy the home may take out construction and erosion-control permits without Dwelling Contractor Certification; required building permits and licensed-trade requirements still apply^4,9.

For unincorporated land, Richland County enforces comprehensive zoning, shoreland, subdivision and floodplain rules, but general land-use authority varies by location². The county issues land-use permits in Akan, Buena Vista, Dayton, Eagle, Forest, Henrietta, Marshall, Orion, Richland, Richwood, Westford and Willow townships; Ithaca and Rockbridge have separate local contacts². Confirm the parcel’s land-use authority with the Zoning & Sanitation Department before filing².

Every township remains under county-administered floodplain, shoreland and wetland zoning¹. Minimum dwelling floor area and structural setbacks depend on the applicable zoning district^1,2. In unincorporated shoreland areas, buildings generally must sit at least 75 feet from the ordinary high-water mark, subject to exceptions and setback averaging¹¹.

Richland County requires a separate sanitary permit for each private wastewater or non-plumbing sanitation system in unincorporated areas and incorporated areas without their own sanitary code³. Begin with a certified soil tester; a plumber submits the sanitary-permit application and plans to the Zoning & Sanitation Department, with a maintenance agreement registered on the deed^1,12. The county lists a $550 sanitary-permit fee and notes that a state plan may be required; the published process generally takes 2 to 6 weeks^1,12.

Only 6.1% of county soils are rated without severe limitations for a conventional septic drain field, so make the soil test and system design a purchase contingency¹³. Where public sewer is available, plumbing fixtures must connect to it; otherwise, a private sewage system must be installed before water service connects to a structure with plumbing³. A new dwelling using private onsite wastewater cannot receive its UDC building permit until the sanitary permit is issued⁹. Existing septic systems require proof of checking or pumping every three years¹².

We could not confirm permission for long-term RV living or temporary camping on private land in Richland County; ask the Zoning & Sanitation Department about the parcel and proposed use². County-regulated trailer camps and campgrounds limit a unit’s stay on one site to 30 days, with an extension not exceeding 60 days⁵. Floodplain campgrounds have additional highway-ready-unit, land-use-permit and removal requirements; their separate 180-day continuous-occupancy limit does not establish permission to live in an RV on a private parcel¹⁴.

Richland County treats cabins as dwellings, with minimum floor area varying by zoning district; ask the Zoning Office for the parcel’s minimum before choosing a tiny-home plan¹. A habitable cabin without interior plumbing or running water requires a county-approved non-plumbing sanitation system³. The system must be NSF approved, with a notarized maintenance agreement recorded on the deed and submitted with the sanitary-permit application; sanitary approval comes before the land-use permit¹.

For a rural home project, use this order:

1. Ask the Zoning & Sanitation Department to identify the zoning authority, district, land-use requirements and UDC inspector^1,2.
2. File the soil test and obtain the sanitary permit before the building permit is issued^1,9.
3. Obtain access approval from WisDOT for a state road, the County Highway Department for a county road or the town chairman for a town road; any required driveway permit comes before the land-use permit¹.
4. Obtain the land-use permit and county address sign, then apply for the UDC building permit through the inspector’s required process; some municipalities use their own applications rather than Wisconsin’s eSLA system^1,4.
5. Wait for all required approvals before construction starts¹.
6. Request the required UDC inspections and occupy only after a final inspection finds no major health or safety violations^7,9.

Before buying rural Richland County land, ask the Zoning & Sanitation Department to confirm the proposed use and structural setbacks². For lots in a county subdivision, direct access to public streets is required; private roads or easements cannot provide the proposed subdivision access¹⁵. Only 39.5% of county land has a slope of 15% or less, and only 6.1% of soils avoid severe conventional-drain-field limitations, so buildable-area and soil-test contingencies are useful¹³.

Wisconsin generally requires advance notice to DNR before private-well construction, with exceptions and separate high-capacity-well approvals⁶. Ask the county zoning office about unconfirmed county well-permit and floodplain-development details². County-zoned mobile home parks require a conditional use permit and at least 5 acres; that park minimum is not a general residential-lot minimum⁵. The county’s median property-tax bill is $2,579 per year, with an effective rate of 1.4%¹³.
