This bill modifies the existing legal framework surrounding Accessory Dwelling Units (ADUs) by expanding their definition and allowing for detached units. The definition of an ADU is amended to specify that it can be located on a lot containing a single-family dwelling, rather than being limited to being within or attached to the principal dwelling. New definitions for "attached unit" and "detached unit" are introduced, clarifying the distinctions between the two. The bill also increases the maximum allowable square footage for ADUs, stipulating that the total living space of an accessory dwelling unit shall not exceed 950 square feet, while ensuring it cannot be restricted to less than 750 square feet.

Additionally, the bill mandates that municipalities must allow one detached accessory dwelling unit as a matter of right, without imposing additional requirements for lot size or other controls beyond those applicable to single-family dwellings. It also prohibits municipalities from requiring a familial relationship between occupants of the principal and accessory dwelling units and allows for the conversion of existing structures into ADUs, regardless of current dimensional requirements. The act is set to take effect on July 1, 2025.
