This bill proposes amendments to the General Laws in Chapter 23-27.3, specifically revising the State Building Code. It increases the membership of the building code standards committee from thirteen to twenty-five, ensuring representation from various professionals such as architects and engineers. The bill sets out the terms of appointment, including staggered initial terms and three-year terms thereafter, and changes the quorum requirement to a majority of current members instead of the previous thirteen. It also details the process for member removal by the governor and defines the committee's powers, including hiring necessary assistance. The committee is authorized to adopt and administer a state building code, resolve code conflicts, and establish a rehabilitation code for existing buildings. The bill includes insertions regarding committee appointments, quorum requirements, and the inclusion of small multiple dwellings in the residential code, while deleting the old quorum number and previous dwelling classifications.

Additionally, the bill requires the state building code to be updated with specific provisions for buildings with six or fewer units, such as maximum building height and egress travel distance, without mandating the installation of fire sprinkler systems or a fire resistance rating exceeding two hours. The state fire marshal and building commissioner are tasked with developing recommendations to resolve fire safety and building code conflicts by July 1, 2025, with implementation by January 1, 2026. The bill also calls for the development of standards for single-exit stairways in buildings up to six stories, known as "point access blocks," with the same deadlines for recommendations and implementation. The act is set to take effect immediately upon passage.
