The bill amends zoning ordinance definitions in Chapter 45-24 of the General Laws, introducing a new definition for "Adaptive reuse" and renumbering subsequent definitions to accommodate this change. It provides detailed descriptions for various zoning-related terms, such as "Accessory dwelling unit (ADU)" and "Building height," and specifies that these definitions are to be used in all local ordinances under this chapter. The bill also outlines the permitted uses within residential, industrial, and commercial zoning districts, including households, community residences, and family daycare homes, except where residential use is prohibited for health or safety reasons. Furthermore, the bill includes provisions for temporary housing in cases of building inhabitation due to casualties, accessibility for people with disabilities, and the allowance of accessory dwelling units in owner-occupied residences for family members with disabilities or those aged 62 or older. It declares plant agriculture as a permitted use in all zoning districts, subject to certain conditions. The bill introduces new language () regarding "adaptive reuse," allowing the conversion of commercial buildings into residential units or mixed-use developments, with at least 50% of the existing gross floor area being developed into residential units, and exempts these developments from off-street parking requirements of over one space per dwelling unit. The bill also sets forth conditions for high-density development in adaptive reuse projects, including a percentage of low- and moderate-income housing and access to public sewer and water services. The bill is set to take effect on January 1, 2024.
