The bill amends several sections of the General Laws in Chapter 45-24, focusing on zoning ordinances. It introduces a new definition for "co-living housing," which describes a specific residential development with units that provide independently rented and lockable living and sleeping spaces, while requiring occupants to share sanitary and/or food preparation facilities with other units. The bill clarifies that existing dwelling units cannot be converted into co-living housing unless authorized by a local zoning ordinance.

Additionally, the bill establishes standard provisions that zoning ordinances must address, including authorizing community living options such as co-living housing in areas serviced by transit and other services. It specifies that co-living housing that meets applicable building and fire code requirements may be allowed in adaptive reuse developments.

The act is set to take effect on January 1, 2026.
