Yes, Wisconsin permits full-time RV living, but local zoning and health codes impose critical constraints. State law treats RVs as temporary dwellings unless permanently affixed to land, triggering municipal enforcement. Counties like Dane and Milwaukee enforce 2026 updates to their zoning ordinances, requiring RV parks to secure conditional-use permits for long-term occupants. Off-grid parking on private property often violates county subdivision rules unless the land is legally subdivided for residential use.
Key Regulations for Living in an RV Full Time in Wisconsin
- Zoning Ordinances: Municipalities classify RVs as recreational or accessory dwellings; permanent occupancy typically violates residential zoning unless the RV is sited in a licensed park. Dane County’s 2026 amendments now mandate RV parks to obtain conditional-use permits for stays exceeding 180 days annually.
- Health and Safety Codes: Wisconsin Administrative Code § SPS 321.09 requires RVs used as primary residences to meet minimum square footage, sanitation, and egress standards. Local health departments, such as Milwaukee’s, inspect off-grid setups for compliance with wastewater disposal and potable water access.
- Property Tax and Land Use: Counties assess RVs as personal property unless permanently affixed to a foundation. Walworth County’s 2025 enforcement crackdown penalizes undeclared long-term RV dwellings on agricultural or vacant lots, citing violations of Wis. Stat. § 70.32(2)(a).
