Do you need a building permit 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.12 Construction may begin only after plans are approved and the building permit is issued and posted.18 Footing, foundation, rough-work, insulation and final building inspections are required for new covered dwellings; request them from the inspector identified on the UDC permit.19 A building permit does not replace a county septic permit, floodplain permit, shoreland approval or other parcel-specific land-use approval.20 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 permits21.
Who issues building permits in Pepin County, and how do you reach them?
Pepin County's checklist directs building-permit applicants in every town to the Uniform Dwelling Code permit issuer at 715-556-0066.22 Inside a city or village, ask that municipality who issues its UDC building permit; local enforcement arrangements may differ.2 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 authority.23 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 documents.24 The published county fee schedule includes land-use and sanitary permit fees, but the amount depends on the work.25
Does Pepin County have zoning?
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.34 Five townships and the City of Durand and Villages of Pepin and Stockholm administer their own zoning.5 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 centerline.26 Shoreland setbacks also apply, with the exact line requiring parcel review.27 Bluffland controls in selected parts of the Towns of Pepin and Stockholm include height limits tied to location and approval type.28 Pepin County sets no countywide minimum dwelling size under its zoning; locally zoned areas may set their own dimensional requirements15. 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 feet29.
How do septic permits work in Pepin County?
Pepin County requires a separate sanitary permit before a private sewage system is installed, replaced, repaired, reconnected or modified, except for minor repairs.6 A licensed plumber designs and installs the system from a certified soil test and obtains the sanitary permit.30 County staff inspect installations and reconnections, including specified final inspections before work is covered.731 Only 11.1% of mapped soils avoid a very-limited rating for a conventional drain field, so establish septic feasibility before fixing the homesite.32 Every Pepin County property used for human habitation must have a septic system or connect to public sewer, including addresses inside cities and villages.33
Can you live in an RV or tiny home on your land in Pepin County?
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 County10. 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 permit1314. 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 in11. County shoreland, floodplain, bluffland and sanitary rules can also apply13. Any property used for human habitation must have a septic system or connect to public sewer12. A chemical, composting, incinerating or other non-water-using toilet still requires a county sanitary permit, fee and recorded agreement34. We could not confirm a county rule on temporary camping on private land; ask Pepin County Land Conservation & Planning23.
Building a home in Pepin County: what are the steps?
- 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 authority.235
- Confirm zoning approval and any county shoreland, floodplain, bluffland or highway-setback limits before fixing the site plan.435
- 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.625
- Apply to the correct UDC building-permit issuer with plans, contractor information, required data and fees.24
- 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 remain.16
What should you check before buying land in Pepin County?
Confirm the parcel's municipality, local zoning and county overlays before assuming a use or building location is allowed.59 Check septic feasibility early because only 11.1% of mapped soils avoid a very-limited rating for a conventional drain field.32 Shoreland and bluffland areas have specific lot dimensions, setbacks and other limits.373827 Every floodplain development, including fill, needs a county permit.39 Pepin County also regulates qualifying land divisions under Chapter 18.40 A new private well requires a Wisconsin DNR notification number before construction; county well-permit requirements were not established.17 Ask the Highway Department about county-road access, while a state-highway connection requires a WisDOT driveway permit.4142
Watch-outs
- No general countywide zoning does not mean no land-use rules: county sanitary, floodplain and shoreland controls apply countywide, and locally administered zoning may also control the parcel.345
- Pepin County requires a floodplain permit for all development in the floodplain, including placement of fill.43
- Pepin County sets no countywide rule on RV living, tiny homes or minimum home size, but township, city and village zoning in the locally zoned areas, county sanitary rules and the septic-or-sewer requirement still apply; ask the parcel's town, city or village before buying101112.

A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
