The bill proposes amendments to the General Laws, focusing on the chapters related to mobile and manufactured homes and zoning ordinances. It introduces a new section, 31-44-23, to Chapter 31-44, which exempts certain manufactured homes from the chapter's provisions if they are not located in a mobile and manufactured home park and meet criteria in § 45-24-31. Additionally, the bill amends Chapter 45-24, effective January 1, 2024, to include a comprehensive list of definitions for terms used in zoning ordinances, such as "Accessory dwelling unit (ADU)," "Aggrieved party," "Applicant," and others, to provide clarity for local ordinance creation. Notably, it defines "manufactured home" in alignment with federal standards and specifies how building height measurements should be calculated, with exclusions for flood hazard areas.

The bill also outlines that zoning ordinances must list all permitted land uses and provides a procedure for evaluating proposed land uses not specifically listed. It ensures that certain uses, like households and community residences, are permitted in most districts, and addresses the temporary use of mobile and manufactured homes due to casualties. It allows for accessory dwelling units as reasonable accommodations and recognizes plant agriculture as a permitted use. The bill promotes adaptive reuse by allowing commercial buildings to be converted into residential or mixed-use developments, with specific provisions for off-street parking exemptions and high-density development conditions. Additionally, it permits towns and cities to consider certain manufactured homes as single-family homes on appropriately zoned lots, with the act taking effect upon passage.
