WHEREAS, Massachusetts faces an urgent need to expand the supply of housing to address affordability challenges, support economic growth, and ensure access to safe and stable homes for people and familiesacross the state;

WHEREAS, building types that enable efficient use of land and support feasible mid-rise residential development—including single-stair construction under appropriate conditions—can play a critical role in increasing housing production in areas with existing infrastructure and services, as recommended by the Unlocking Housing Production Commission;

WHEREAS, Massachusetts is committed to incorporating advances in fire prevention and life-safety systems and ensuring that building code requirements are grounded in rigorous technical analysis to maximize public safety;

WHEREAS, single-stair multifamily residential buildings of moderate height are widely permitted in other states and internationally, subject to specific design, fire-safety, and operational safeguards;

WHEREAS, current Massachusetts building code requirements generally require two means of egress for multifamily residential buildings above three stories, limiting the feasibility of mid-size residential construction across the state;

WHEREAS, it is in the public interest to convene relevant technical experts and stakeholders to evaluate, based on evidence and best practices, the conditions under which single-stair multifamily residential buildings may be safely permitted in Massachusetts, and to recommend any necessary regulatory updates;

NOW, THEREFORE, I, Maura T. Healey, Governor of the Commonwealth of Massachusetts, by virtue of the authority vested in me by the Constitution, Part II, c. 2, § I, Art. I, do hereby order as follows:

Section 1.  Establishment of the Technical Advisory Group on Single-Stair Multifamily Residential Buildings

There is hereby established, within the Office of the Governor, a Technical Advisory Group on Single-Stair Multifamily Residential Buildings (the “Technical Advisory Group”).

The purpose of the Technical Advisory Group shall be to study, and advise the Governor and Lieutenant Governor, on the conditions under which single-stair multifamily residential buildings should be permitted in Massachusetts, subject to appropriate safeguards to adequately address health and safety concerns.

The Technical Advisory Group shall specifically:

1. Conduct a comparative technical analysis of the safety performance of single-stair multifamily residential buildings relative to buildings with two or more means of egress, drawing on empirical data, peer-reviewed research, and applicable standards;
2. Recommend updates to the Massachusetts State Building Code (780 CMR) that would permit the construction of single-stair multifamily residential buildings, with proposed height and unit limits; and
3. Identify and recommend measures to mitigate any health and safety impacts unique to single-stair multifamily residential buildings. The Technical Advisory Group shall submit a final report reflecting its recommendations to the Governor and Lieutenant Governor not later than 12 months from the effective date of this executive order, unless extended by the Governor.

For purposes of this Executive Order, a “single-stair multifamily residential building” means a multifamily residential building in which the dwelling units are served by one interior exit stairway as the required means of egress for residents.
