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 rulesClark County, WI
Zoning & raw-land occupancy
Varies locallyClark County Planning & Zoning Division administers countywide land use ordinances (Chapters 20 and 22) in unincorporated areas; incorporated towns/villages may have their own zoning, so confirm locally. source
Dwellings, tiny homes & RVs
Unclear - verifyNo Clark County-specific ordinance on tiny homes or RV occupancy was found; this inherits the state Uniform Dwelling Code baseline, so confirm with the county before building. source
Building permits & codes
Generally allowedBuilding permits follow the statewide Uniform Dwelling Code, but Clark County's Planning & Zoning office is the local permit-issuing authority. source
Septic & composting toilets
RestrictedClark County has its own POWTS ordinance (Chapter 20) administered by the Assistant Zoning Administrator, with the Health Department registering installers and haulers; composting toilets fall under this same framework. source
Greywater reuse
RestrictedNo Clark County-specific greywater ordinance was found; this inherits the state DSPS plumbing code restriction limiting greywater use to permitted subsurface irrigation with a licensed installer.
Rainwater harvesting
Varies locallyNo county-specific rule was found. Outdoor non-potable rainwater collection appears unregulated under the state baseline, while indoor/potable use is restricted under the state DSPS plumbing code.
Private wells & water rights
Generally allowedThe Clark County Health Department handles well water testing (bacteria, and optionally nitrates/fluoride), while well construction standards come from the state's NR 812 code via DNR, with county-delegated inspectors; confirm which county office issues construction permits. source
Living disconnected from utilities
Unclear - verifyNo Clark County ordinance was found addressing full disconnection from electric or gas utilities; this inherits the state-level unclear baseline, so confirm directly with the county.
