Concerns development and use of accessory dwelling units.

This bill requires New Jersey municipalities to permit accessory dwelling units (ADUs) in single-family and two-family residential zones as a standard use, eliminating the need for special approvals beyond standard zoning. It sets specific size limits (minimum 300 sq ft, maximum 1,200 sq ft), height restrictions (max 20 feet), and setback rules (no more than five feet for detached ADUs). The bill also mandates that ADUs must be rented separately from the primary dwelling but cannot be sold separately, and exempts them from fire sprinkler requirements if the primary dwelling does not require them. These provisions directly affect homeowners seeking to build ADUs and municipalities required to update zoning regulations.
