Richland County, Wisconsin requires a Uniform Dwelling Code building permit for every new one- or two-family home, while additions require one in certain townships.1 The county also administers land-use permits in participating towns and sanitary permits for private septic systems.23 Start with the Richland County Zoning & Sanitation Department, then identify the UDC inspector serving the parcel's township.4

Do you need a building permit 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 townships.1 Wisconsin's statewide UDC covers one- and two-family dwellings built since June 1, 1980, and it is enforced in every municipality.7 Construction may begin only after the plans are approved and the building permit is issued and posted.8
The county's published process separates the UDC building permit from the county land-use permit: contact the UDC inspector serving the parcel's township for the building permit, and work with the Zoning & Sanitation Department on county land-use approvals.9 Permit requirements for alterations and additions vary by municipality, so confirm the scope with the township inspector before ordering materials.10
Who handles building permits in Richland County?
Richland County does not present one countywide building inspector for every parcel. The county directs applicants to the UDC inspector serving the project's township, while its Zoning & Sanitation Department handles county land-use review.9 The department publishes inspector information and can be reached at 608-647-2447 or [email protected] at 181 W. Seminary Street, Richland Center, WI 53581.4
During construction, call for inspection of each phase before covering the work; once the work is ready and inspection is requested, the inspector has two business days before it may be covered.11 An owner who currently occupies or will occupy the completed home may take out the construction and erosion-control permits instead of using the certified-contractor arrangement, but the permits themselves are still required.12
Does Richland County have zoning?
Richland County administers zoning and issues land-use permits for participating townships.2 Its published land-use page names Akan, Buena Vista, Dayton, Eagle, Forest, Henrietta, Marshall, Orion, Richland, Richwood, Westford and Willow as townships where the county issues land-use permits.9 Ithaca and Rockbridge direct zoning questions to their own administrators.4
Every township remains under county-administered floodplain, shoreland and wetland zoning, even where general zoning administration differs.9 In unincorporated shoreland areas, buildings generally must sit at least 75 feet from the ordinary high-water mark, subject to listed exceptions and setback averaging.13 County zoning also regulates intended uses and structural setbacks, so use the county GIS and ask the Zoning & Sanitation Department to verify the parcel's district before relying on a seller's description.4
How do septic permits work in Richland County?
Richland County Zoning & Sanitation approves private onsite wastewater systems.3 Begin with a certified soil tester; after the system type is determined and any state approval is obtained, a plumber submits the sanitary-permit application and plans to the county.14 The county says the process generally takes 2 to 6 weeks.14
Site feasibility deserves early attention: only 6.1% of county soils are rated without severe limitations for a conventional septic drain field.15 That does not make a parcel unbuildable, but it makes the soil test and system design consequential before purchase. Richland County must receive proof that the system was checked or pumped every three years.14 A new dwelling using private onsite wastewater cannot receive its building permit until the sanitary permit has been issued.10
Can you live in an RV or tiny home in Richland County?
We could not confirm a countywide rule allowing long-term RV living or temporary camping on private land in Richland County. Ask the Zoning & Sanitation Department about the parcel's zoning district, intended occupancy and sanitation plan before placing or occupying an RV. The Wisconsin state-park camping rules do not answer what is allowed on private property.
For tiny homes, Richland County treats every cabin as a dwelling, and minimum floor area varies by zoning district.9 That means a small cabin or tiny home is not automatically exempt from dwelling, land-use, building or sanitation requirements. A manufactured home can qualify as a dwelling under Wisconsin's UDC, but local zoning and sanitary approvals still apply.16 If a cabin has no interior plumbing, the county requires an approved non-plumbing sanitation system and sanitary-permit application.9
Building a home in Richland County: what are the steps?
For a rural home project, use this order:
- Ask the Zoning & Sanitation Department to identify the zoning district, county land-use requirements and the township UDC inspector.29
- Hire a certified soil tester and complete the sanitary-permit process before the building permit is issued.1410
- Obtain any driveway approval from the authority maintaining the road; a driveway permit must precede the county land-use permit when applicable.9
- File the land-use application and other local prerequisites, then submit at least two plan sets to the municipality or authorized UDC inspection agency.17
- Wait for plan approval and the posted building permit before construction starts.8
- Request each required inspection before covering work, then occupy only after a final inspection finds no major health or safety violations.1118
What should you check before buying land in Richland County?
Confirm zoning, legal access, wastewater feasibility, water and flood constraints before making the offer unconditional. Richland County regulates land uses through permits and reviews proposed uses and structural setbacks for code compliance.4 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 especially useful.1915
For a private well, Wisconsin generally requires advance notice to DNR before construction, although some exceptions and separate high-capacity-well approvals apply.6 Check the mapped floodplain because floodway construction is tightly limited and new structures, wells and sewage systems are prohibited there.20 For access onto a state highway, WisDOT requires a connection permit.21 The county's median property-tax bill is $2,579 per year, with an effective rate of 1.4%.2223
Watch-outs
- A seller's statement that a township is unzoned does not remove county floodplain, shoreland, wetland, land-division or sanitation requirements.9
- Do not assume a small cabin escapes dwelling rules; Richland County treats all cabins as dwellings and varies minimum floor area by zoning district.9
- Long-term RV occupancy and temporary private-land camping remain unconfirmed; ask the Zoning & Sanitation Department about the specific parcel and proposed use.4
- A driveway permit, when applicable, must be secured before the county land-use permit can be issued.9
