AB 365 Wisconsin Assembly · 2025-2026 Regular Session

Relating to: local and private regulation of accessory dwelling units. (FE)

AB 365 requires cities, towns, and homeowners' associations to allow accessory dwelling units (ADUs) - small secondary homes on existing properties - as a "permitted use" without special permits on eligible parcels. It prohibits local governments and HOAs from charging extra fees (beyond standard building permits), imposing stricter design rules than for main homes, requiring separate utilities or parking, or banning ADUs via deed restrictions. The bill permits size limits (capping ADUs at 75% of the main home's square footage on single-family parcels) but bans all other restrictive rules. It directly affects local zoning authorities, municipal ordinances, and HOA covenants governing residential properties.
