The proposed bill introduces CHAPTER 24.8, titled "Home-Fit Dwelling Units," to Title 45 of the General Laws, establishing new accessibility standards for residential dwelling units aimed at individuals with physical disabilities. Key provisions include a requirement that at least 25% of new construction of covered dwelling units must meet Type A accessibility standards, while first-floor units in multi-story buildings must fully comply with these standards, and upper floors must adhere to Type B adaptable unit standards. Custom-built homes and existing permits prior to the chapter's effective date are exempt from these requirements. The bill also mandates that sellers of newly constructed units disclose compliance with these standards to prospective buyers and outlines a process for requesting exceptions to the design standards.

Additionally, the bill assigns the director of housing the responsibility to consult stakeholders to develop implementation rules and regulations, and it establishes an incentive program to encourage compliance by January 1, 2026. It requires that applications for construction permits include acknowledgments of the design features and any public financial assistance received, with penalties for violations such as providing false information or failing to comply with design features. The enforcement of these provisions will be managed by the Department of Housing or through private action, allowing for a three-year period to bring forth a cause of action upon discovering noncompliance. The act will take effect upon passage.
