The bill amends Sections 45-23-44 and 45-24-33 of the General Laws to enhance regulations regarding land subdivision and zoning ordinances. In Section 45-23-44, it introduces new provisions that require municipalities to establish clear physical design requirements for subdivisions, ensuring that local regulations specify objective standards. It allows municipalities to set minimum lot sizes per zoning district, with specific limitations outlined in § 45-24-33(d). Additionally, the bill mandates that wetland buffers be included in the calculation of minimum lot areas while maintaining existing definitions and protections for wetlands.

In Section 45-24-33, the bill requires zoning ordinances to address land use, building dimensions, and environmental protections, with a notable change mandating special provisions for development incentives by July 31, 2026. These incentives are aimed at promoting benefits such as increased open space and improved traffic conditions. The bill establishes new parameters for minimum lot sizes, allowing municipalities to set their own limits but capping them at 2,500 square feet for lots near public transit, 5,000 square feet for lots served by public water and sewer, and one acre for all other lots. It also includes provisions for calculating buildable lot areas, transferring development rights, and regulating development near scenic areas, with the act taking effect immediately upon passage.
