This bill aims to facilitate the development of accessory dwelling units (ADUs) in New Jersey by mandating that municipalities adopt or amend land use regulations to allow for their creation on lots containing single-family dwellings. It recognizes ADUs as a valuable housing option that can help meet the state's housing demand while providing affordable living spaces for various groups, including family members and individuals with disabilities. The bill outlines specific requirements for municipalities, including that ADUs must be permitted as a right in zones where single-family or two-family dwellings are allowed, and it prohibits certain restrictions that could hinder their development, such as requiring a passageway between the ADU and the principal dwelling or imposing minimum age requirements for occupants.

Additionally, the bill streamlines the approval process for ADUs by classifying applications as ministerial actions, which do not require public hearings. If a municipal agency does not act on a complete application within 60 days, the application is automatically approved. The legislation also ensures that municipalities cannot impose additional standards beyond those specified in the bill, thereby preventing delays or denials based on other local ordinances. Overall, the bill seeks to enhance housing availability and affordability in New Jersey by promoting the development of ADUs while maintaining necessary safety and building code requirements.
