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.

The local rulesKewaunee County, WI
Zoning & raw-land occupancy
Varies locallyKewaunee County does not administer general zoning; it only handles shoreland and floodplain zoning countywide. General land-use zoning is set town by town, so you must contact the Town Zoning Administrator where the property is located. source
Dwellings, tiny homes & RVs
Unclear - verifyNo county-specific rules on tiny homes or RV occupancy were found; dwelling construction falls under the state Uniform Dwelling Code administered by DSPS. Any additional limits on tiny homes or RVs would be set by the town, not confirmed at county level.
Building permits & codes
Generally allowedOne- and two-family dwelling permits are handled under the state Uniform Dwelling Code by registered inspection agencies such as Inspection Specialists, LLC serving Kewaunee County municipalities. The county's Land & Water Conservation office issues its own zoning permit for shoreland-affected properties. source
Septic & composting toilets
RestrictedKewaunee County's Sanitary Ordinance (Chapter 15) regulates POWTS and non-plumbing sanitation systems countywide where public sewer isn't available; non-plumbing systems like composting toilets are only allowed if the building has no water service or plumbing at all.
Greywater reuse
RestrictedNo Kewaunee County-specific greywater ordinance was found; this falls back to the state DSPS plumbing code, which requires a permit and licensed installer for reuse systems.
Rainwater harvesting
Varies locallyNo county ordinance restricting basic non-potable rainwater collection was found, so this follows the state baseline; not confirmed for any county-added restriction.
Private wells & water rights
Generally allowedWells are governed by the state Well and Pump Code (NR 812), but the county's Public Health Department strongly urges annual testing given the area's karst geology and groundwater vulnerability; test kits are available from that office. source
Living disconnected from utilities
Unclear - verifyNo county ordinance was found addressing full disconnection from electric or gas utilities; the sanitary ordinance does require connecting to public sewer if it becomes available, but that doesn't extend to electric or gas.
