The local rulesAshland County, WI
Zoning & raw-land occupancy
Varies locallyAshland County Zoning Administration enforces countywide Use District and Subdivision rules, but towns like La Pointe administer those same county ordinances locally via agreement. Confirm with both county zoning and your town. source
Dwellings, tiny homes & RVs
Varies locallyNo county-specific tiny-home or RV ordinance was found; the county defers to the state Uniform Dwelling Code and tells residents to check with their Town Chairman or Clerk for local permits. source
Building permits & codes
Generally allowedThe county issues building permits through its Zoning office at the Courthouse, under the state UDC framework; shoreland parcels have extra requirements. source
Septic & composting toilets
RestrictedAshland County's Private Sewage System Ordinance requires state-code-compliant septic/holding tanks (SPS 383) with no grandfather exemption, a sanitary permit, and licensed installer. Composting/incinerating toilets must be NSF-certified, and privies follow state storage-capacity rules. source
Greywater reuse
Unclear - verifyNo Ashland County greywater ordinance was found; the state DSPS plumbing code baseline likely applies, generally restricting greywater to subsurface irrigation with a permit and licensed installer. Confirm specifics with the county or state.
Rainwater harvesting
Unclear - verifyNo county-specific rainwater ordinance was found; Wisconsin's state plumbing code baseline is generally permissive for basic outdoor, non-potable collection. Not confirmed for indoor/potable use at the county level.
Private wells & water rights
Generally allowedWell permitting is handled by the Wisconsin DNR, not Ashland County; the county directs residents to DNR for permits and well records. source
Living disconnected from utilities
Unclear - verifyNo Ashland County rule directly bans disconnecting from electric or municipal utilities, but occupancy in practice requires an approved sanitary system, a separate sanitation requirement, not a utility mandate. Check with your Town Chairman or Clerk for any added local rules. source
