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

Yes. Every town in Pepin County requires a Uniform Dwelling Code building permit for a new one- or two-family home, and Wisconsin's statewide UDC covers these dwellings and specified additions and alterations^1,2. Construction may begin only after plans are approved and the building permit is issued and posted². Footing, foundation, rough-work, insulation and final building inspections are required for new covered dwellings; request them from the inspector identified on the UDC permit⁶. A building permit does not replace a county septic permit, floodplain permit, shoreland approval or other parcel-specific land-use approval¹. Wisconsin's UDC allows occupancy after a final inspection with no major health or safety violations, and the dwelling's exterior must be finished within two years of the permit; some municipalities also issue occupancy permits².

Pepin County's checklist directs building-permit applicants in every town to the Uniform Dwelling Code permit issuer at 715-556-0066¹. Inside a city or village, ask that municipality who issues its UDC building permit; local enforcement arrangements may differ². Start with Pepin County Land Conservation & Planning at 715-672-8897 for county septic permits, county land-use controls and identification of the parcel's local zoning authority⁴. A UDC application requires plans, contractor information, required data and fees, while county sanitary or land-use applications may require soil evaluations, site plans and supporting documents⁸. The published county fee schedule includes land-use and sanitary permit fees, but the amount depends on the work⁹.

Pepin County does not have a general countywide zoning ordinance, but county sanitary, floodplain and shoreland/wetland controls apply countywide; bluffland, highway-setback and other overlays apply only in specified locations^3,4. Five townships and the City of Durand and Villages of Pepin and Stockholm administer their own zoning⁴. County highway setbacks in the Towns of Lima, Pepin and Stockholm measure 63 feet from a town-road centerline, 75 feet from a county-road centerline and 110 feet from a state-highway centerline⁴. Shoreland setbacks also apply, with the exact line requiring parcel review¹⁰. Bluffland controls in selected parts of the Towns of Pepin and Stockholm include height limits tied to location and approval type¹¹. Pepin County sets no countywide minimum dwelling size under its zoning; locally zoned areas may set their own dimensional requirements³. In bluffland areas under Chapter 19, a main building needs a side yard of at least 25 feet and an accessory building a side yard of 10 feet¹².

Pepin County requires a separate sanitary permit before a private sewage system is installed, replaced, repaired, reconnected or modified, except for minor repairs⁵. A licensed plumber designs and installs the system from a certified soil test and obtains the sanitary permit⁴. County staff inspect installations and reconnections, including specified final inspections before work is covered^4,13. Only 11.1% of mapped soils avoid a very-limited rating for a conventional drain field, so establish septic feasibility before fixing the homesite¹⁴. Every Pepin County property used for human habitation must have a septic system or connect to public sewer, including addresses inside cities and villages⁴.

Pepin County has no countywide zoning ordinance, so the county itself sets no general zoning rule on living in an RV on private land in unincorporated Pepin County³. The same holds for tiny homes: the county applies no general zoning occupancy restriction, and a tiny home built as a new one- or two-family dwelling still needs a Uniform Dwelling Code building permit^3,6. That is not a free pass. Five townships and the City of Durand and Villages of Pepin and Stockholm run their own zoning, so ask the parcel's town, city or village before moving in⁴. County shoreland, floodplain, bluffland and sanitary rules can also apply³. Any property used for human habitation must have a septic system or connect to public sewer⁴. A chemical, composting, incinerating or other non-water-using toilet still requires a county sanitary permit, fee and recorded agreement⁵. We could not confirm a county rule on temporary camping on private land; ask Pepin County Land Conservation & Planning⁴.

1. Give Pepin County Land Conservation & Planning the parcel location and proposed work so staff can identify county controls and the correct town, city or village zoning authority⁴.

1. Confirm zoning approval and any county shoreland, floodplain, bluffland or highway-setback limits before fixing the site plan⁴.

1. Complete the soil evaluation and have a licensed plumber obtain the county sanitary permit before a building or land-use permit is issued for a home using septic^5,9.

1. Apply to the correct UDC building-permit issuer with plans, contractor information, required data and fees⁸.

1. An owner who occupies or will occupy the home may take out construction and erosion-control permits without Dwelling Contractor Certification, but all required permits and UDC rules remain².

1. Begin only after approval and issuance, then request each required building inspection^2,6.

Confirm the parcel's municipality, local zoning and county overlays before assuming a use or building location is allowed⁴. Check septic feasibility early because only 11.1% of mapped soils avoid a very-limited rating for a conventional drain field¹⁴. Shoreland and bluffland areas have specific lot dimensions, setbacks and other limits^10,12. Every floodplain development, including fill, needs a county permit¹⁵. Pepin County also regulates qualifying land divisions under Chapter 18¹⁶. A new private well requires a Wisconsin DNR notification number before construction; county well-permit requirements were not established⁷. Ask the Highway Department about county-road access, while a state-highway connection requires a WisDOT driveway permit^17,18.
