This bill aims to promote the development of accessory dwelling units (ADUs) in New Jersey by establishing clear regulations for municipalities. It mandates that municipal land use regulations must allow for the creation of ADUs and prohibits any regulations that would restrict property owners from developing these units. The bill defines key terms related to ADUs and outlines the responsibilities of municipalities in adopting model ordinances provided by the Commissioner of Community Affairs. Additionally, it streamlines the approval process for ADU applications, requiring municipalities to treat these applications as ministerial actions without public hearings and mandates a decision within 60 days.

The legislation also restricts associations managing planned real estate developments from enforcing unreasonable restrictions on ADUs, ensuring that any conflicting provisions are rendered void. Municipalities must adopt one of two model ordinances created by the Commissioner, and any differing regulations must be submitted for approval within 60 days. The bill further stipulates that if a municipal agency fails to act on an application within the specified timeframe, the application is automatically deemed approved. The Commissioner is tasked with implementing necessary regulations and publishing the model ordinances, with the bill set to take effect six months after enactment.
