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 rulesGreen County, WI
Zoning & raw-land occupancy
RestrictedGreen County Land Use & Zoning Department administers countywide general, shoreland, and floodplain zoning; a land use/zoning permit is required before land disturbance or building placement. source
Dwellings, tiny homes & RVs
Varies locallyThe statewide Uniform Dwelling Code is the baseline, but enforcement is handled town by town; the Town of York, for example, has its own certified inspector rather than relying on the county. Confirm with your specific town. source
Building permits & codes
Varies locallyBuilding permits may be issued by the county or by an individual town depending on which body has adopted UDC enforcement locally; identify jurisdiction before applying. source
Septic & composting toilets
RestrictedGreen County administers the state POWTS sanitary code and requires zoning department release before construction proceeds; vault privies (non-plumbing sanitation) are permitted but with specific setback distances from wells, water, property lines, and doors. source
Greywater reuse
RestrictedNo Green County-specific greywater ordinance was found; presume the statewide DSPS plumbing code (subsurface irrigation, licensed installer, state permit) applies without local modification.
Rainwater harvesting

Private wells & water rights

Living disconnected from utilities
