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

This bill establishes statewide standards for accessory dwelling units (ADUs) in New Jersey, requiring municipalities to allow ADUs as a permitted use in single-family and two-family residential zones. It sets specific requirements including minimum 300 square feet and maximum 1,200 square feet floor area, maximum height of 20 feet, and no more than 5-foot sideyard and rear yard setbacks. The bill mandates that applications for ADUs must be approved ministerially within 60 days without public hearings, prohibits selling ADUs separately from primary dwellings, and requires municipalities to include plans for promoting affordable ADUs in their housing elements. Municipalities may impose reasonable restrictions in specific circumstances, such as historic districts or very small lots, but cannot prohibit ADUs outright.
