From the Wisconsin guide
Wisconsin leaves this to counties and towns. Of the 72 counties, 24 have their own RV answer: 1 allowed, 4 temporary-only, 18 limited and 1 prohibited, and 48 are unanswered.6 St. Croix County is the one that allows it, through a seasonal travel-trailer land-use permit for one camping unit on a vacant parcel; Sawyer County and Sauk County are temporary-only; Menominee County, Lincoln County and Iron County are limited.6 State park rules that cap stays at 14 days in any 21 days apply to campsites, not to your own land.29 The Wisconsin RV-living list has the conditions.
For tiny homes, 12 counties have an answer: 1 allowed and 11 limited, with 60 unanswered.7 Oneida County allows a tiny home as a single-family dwelling in its Single Family Residential district, while Oconto County, Barron County, Sawyer County and Waushara County answer with limits, often minimum sizes.7 We could not confirm any statewide tiny-home definition; the Uniform Dwelling Code is the statewide construction standard for one- and two-family dwellings.2 See the tiny-home list.
