The bill amends the General Laws related to mobile and manufactured homes and zoning ordinances. It specifies that the chapter on "Mobile and Manufactured Homes" does not apply to manufactured homes outside of mobile home parks that meet criteria in § 45-24-31, and it adds a new section, 31-44-23, to clarify this. Additionally, the bill updates Chapter 45-24, "Zoning Ordinances," with new definitions for terms like "Accessory dwelling unit (ADU)," "Manufactured home," and others, to provide clarity for local zoning ordinances. It also outlines how certain measurements, such as building height, should be calculated, with exclusions for flood hazard areas. These changes are set to take effect on January 1, 2024.

The bill further details the definitions of various zoning-related terms, including "Household," which is not to be limited to fewer than three unrelated persons, and "Nonconformance," which differentiates between nonconforming uses and dimensions. It introduces provisions for permitted land uses within zoning districts, procedures for evaluating unlisted land uses, and the inclusion of certain uses like households and community residences in most districts. The bill allows for temporary mobile home use during residential structure repairs, ensures disability access, permits accessory dwelling units for family members with disabilities or those aged 62 or older, and recognizes plant agriculture as a permitted use. Additionally, it promotes adaptive reuse of commercial buildings for residential or mixed-use developments, with specific conditions for high-density projects and exemptions from off-street parking requirements. The bill also allows for the consideration of manufactured homes as single-family homes on appropriately zoned lots, with the act taking effect upon passage.
