Concerns development of accessory dwelling units and related municipal land use regulations.

This New Jersey bill (A 3488) requires municipalities to allow accessory dwelling units (ADUs) - secondary housing units like in-law apartments or backyard cottages - in single-family and two-family residential zones. It mandates that local land use regulations permit ADUs as a "permitted use as of right," removing barriers such as excessive parking requirements, owner-occupancy mandates, or restrictions on occupant relationships. The bill also requires automatic approval (ministerial action) for ADU applications without public hearings, while prohibiting municipalities from imposing additional fees or fire sprinkler requirements beyond those for the main dwelling. It directly affects homeowners seeking to build ADUs, municipalities updating zoning rules, and renters who may benefit from expanded housing options within existing neighborhoods. The bill is pending before the Assembly Housing Committee as of January 2026.
