The proposed bill introduces a new chapter, CHAPTER 24.8, titled "Home-Fit Dwelling Units," to Title 45 of the General Laws concerning towns and cities. This chapter establishes requirements for new housing developments with four or more dwelling units that receive state financial assistance or are developed on land owned by or conveyed from the state or a quasi-state entity. Specifically, it mandates that at least 10% of these units comply with Type A accessibility standards and an additional 25% comply with Type B standards, as defined in the ICC A117.1-2017 building code.

The bill includes definitions for key terms such as "Accessibility," "Home-fit," and "Authorized agency," and stipulates that sellers of covered dwelling units must provide written disclosure at the time of first conveyance indicating whether the unit complies with Type A or Type B design provisions.

Additionally, the bill outlines the process for implementing these standards, including the development of criteria for granting waivers from the requirements, which can only be issued by a municipal building official under specific conditions. Municipalities are required to submit annual reports to the executive office of housing, detailing the number of building permits and certificates of occupancy issued that included Type A and Type B standards, as well as the number of waivers granted and the reasons for those waivers. The executive office of housing will compile this information into an annual report for the General Assembly.

The act is set to take effect upon passage for rulemaking and implementation purposes and will apply to covered dwelling units permitted on or after July 1, 2027.
