Housing (Zoning)

AB 194 modifies Wisconsin's housing programs under the Wisconsin Housing and Economic Development Authority. It redefines "developer" to include tribal housing authorities (Section 3) and clarifies "residential housing" to include tax-exempt reservation or trust lands (Section 4). The bill reduces maximum loan limits for housing projects from 33% to 20% of development costs (Section 10) and from 25% to 10% (Section 11). It also requires local governments to submit cost-reduction analyses showing how zoning or fee changes lowered housing costs (Section 7), directly affecting developers, tribal entities, and local governments administering housing programs.

AB 449 requires local governments to allow at least one accessory dwelling unit (ADU) - a separate living space on a single-family property - as a standard permitted use, meaning homeowners can build one without special approvals. Local rules may still limit ADU size (to match the main home's square footage), height, or yard space requirements, but cannot block ADUs entirely. The bill also prohibits using newly created ADUs as short-term rentals (like Airbnb) after a specific date. This directly affects homeowners in single-family zones and local governments that set zoning rules.

SB 473 requires local governments to allow at least one accessory dwelling unit (ADU) per single-family lot as a "permitted use" without special permits, directly affecting homeowners in residential and mixed-use zones. Localities may still set reasonable limits on ADU size (capped at the main house's square footage), height, and setbacks, but cannot impose additional approvals for standard ADUs. The bill also prohibits new ADUs created after its effective date from being used as short-term rentals (like Airbnb), while allowing existing ADUs to remain unaffected. This standardizes ADU access across the state while giving communities flexibility to manage development.

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.
