The bill amends the General Laws in Chapter 45-24, which pertains to zoning ordinances, by introducing and clarifying definitions for a wide range of terms relevant to local zoning and land use. These terms include "Abutter," "Accessory dwelling unit (ADU)," "Cluster," "Community residence," "Day care," "Development," and many others. The definitions are intended to standardize language across local ordinances and ensure clarity in zoning and development processes. The bill also addresses the measurement of building height, particularly in flood hazard areas, and defines the concept of "Cluster" development, which concentrates buildings to preserve open space. It sets clear zoning waivers and licensing requirements for community residences and day care facilities, aligning zoning ordinances with the comprehensive plan adopted pursuant to chapter 22.2 of the title.

Furthermore, the bill defines additional terms such as "Floodplains," "Freeboard," "Halfway house," "Lot," "Mixed use," "Nonconformance," and "Overlay district," among others, to provide clear interpretations within legal and developmental frameworks. Notably, the bill inserts a new definition for "zero lot line development" and adds a new section, 45-24-37, outlining general provisions for permitted uses within zoning districts. It allows for temporary placement of mobile homes in the event of residential buildings being rendered uninhabitable, ensures access for people with disabilities, permits accessory dwelling units for family members with disabilities or those aged 62 or older, and recognizes plant agriculture as a permitted use in all zoning districts with certain exceptions. Additionally, the bill introduces section 45-24-37.1, which establishes minimum housing options as permitted uses in zoning-use districts and promotes the adaptive reuse of residential structures that are at least 20 years old. The bill also specifies conditions for the redevelopment of dwellings to contain additional units, addresses parking requirements, establishes minimum size requirements for dwelling units, and provides for the review of applications and the award of attorneys' fees in cases of municipal non-compliance.
