Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.
The local rulesPepin County, WI
Zoning & raw-land occupancy
Varies locallyPepin County administers zoning in most of the county, but five townships plus the City of Durand, Village of Pepin, and Village of Stockholm run their own zoning independently. Shoreland and Mississippi River Bluffland overlay codes add extra restrictions where the county has jurisdiction. source
Dwellings, tiny homes & RVs
Unclear - verifyNo Pepin County page specifically addresses tiny homes or RV-as-residence standards; this falls to whichever zoning authority, county or town, covers the parcel, under the statewide Uniform Dwelling Code baseline. Not confirmed, ask the relevant zoning administrator.
Building permits & codes
Generally allowedA land use permit is required for building or land-disturbing activity in shoreland areas, and the Bluffland overlay requires permits for buildings, signage, and sewage systems unless exempted, per Pepin County zoning administration. Statewide UDC standards apply underneath. source
Septic & composting toilets
RestrictedPepin County's Chapter 15 Sanitary Code requires all habitable properties to have a septic system or public sewer connection, with installation only by a licensed plumber and county inspection, administering state law (Wis. Stat. §145, SPS 382-387, 391). source
Greywater reuse
Unclear - verifyNo Pepin County ordinance specifically addresses greywater reuse separate from the sanitary/POWTS code; it likely runs through the same Chapter 15 permitting process, but this isn't confirmed. Ask county zoning/planning.
Rainwater harvesting
Unclear - verifyNo Pepin County ordinance or health department page addresses rainwater collection; presumed to follow the statewide baseline of no permit for outdoor non-potable use, but not confirmed locally.
Private wells & water rights
Generally allowedNo Pepin County-specific well ordinance was found beyond the statewide DNR NR 812 Well and Pump Code; well construction is handled through licensed well drillers rather than a distinct county permit. source
Living disconnected from utilities
Unclear - verifyNo Pepin County ordinance directly addresses disconnecting a dwelling from electric or gas utilities; the closest related rule is the mandatory septic or sewer connection under Chapter 15, which doesn't cover other utilities.
