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

SB 247 standardizes rules for accessory dwelling units (ADUs) - secondary homes on the same lot as a primary residence - across cities, towns, and homeowners' associations in Wisconsin. It requires municipalities to allow at least one ADU per eligible parcel "by right" (without special permits), limits ADU size to 75% of the main home's square footage, and bans extra fees, discriminatory design rules, additional parking requirements, or separate utility connections for ADUs. The bill also voids private deed restrictions or HOA rules that block ADUs and prohibits associations from restricting ADUs except for public health/safety reasons. This directly affects homeowners, local governments, and community associations by removing barriers to building ADUs on single-family lots.
