The bill amends Chapter 45-24 of the General Laws by adding a new section titled "Recovery houses." This section defines a recovery house as a residential structure that is properly zoned according to a town or city's zoning ordinance and provides recovery support services for individuals recovering from substance abuse addiction. The bill stipulates that recovery residences must be treated as a residential use of property, granting them the same rights and responsibilities as other residential properties.

Additionally, the bill prohibits cities and towns from enacting any zoning ordinance that imposes restrictions, prohibitions, or other provisions on recovery houses that are not applicable to other residential homes in similar types of structures within the same zoning district. This includes ensuring that recovery houses are not subjected to additional provisions related to state building or fire codes that do not apply to typical residential uses. The act will take effect immediately upon passage.
