Changes to Staircase Requirements in U.S. Apartment Buildings

Historically, U.S. apartment buildings taller than three stories were mandated to have at least two staircases, a regulation aimed at enhancing safety during emergencies such as fires. However, since 2024, several states have begun to relax this requirement for smaller apartment buildings, allowing the construction of single-staircase structures. Proponents argue that this change is a crucial step in addressing the ongoing housing crisis in the United States.

States including Colorado, Connecticut, Maine, Montana, New Hampshire, Texas, and Tennessee have already enacted code changes permitting single-staircase designs. Washington State is set to join this list in July 2026. Additionally, states like California, Hawaii, New York, Minnesota, Oregon, and Virginia are currently conducting studies to assess the implications of adopting similar regulations.

Supporters of the new regulations, such as Stephen Smith, executive director of the Center for Building in North America, assert that allowing single-staircase buildings can facilitate the development of residential units on smaller lots. This shift could potentially lower construction costs and increase the availability of housing in urban areas. Smith notes, “We’re seeing single-stair buildings on what were otherwise unbuildable small lots,” highlighting the practical benefits of this regulatory change.

Despite the potential benefits, the relaxation of safety regulations has raised concerns among critics. Opponents argue that reducing the number of staircases could compromise safety in emergencies, particularly in densely populated buildings. They emphasize that multiple exits are essential for ensuring the safe evacuation of residents during critical situations.

Proponents of the changes maintain that the new regulations are designed with safety in mind, asserting that modern building materials and fire safety technologies can mitigate risks associated with single-staircase designs. However, critics remain skeptical, calling for more comprehensive studies to evaluate the long-term safety implications of these changes.

While proponents cite the potential for increased housing availability, critics highlight the lack of empirical data on the safety outcomes of single-staircase buildings. There is a need for further research to address these concerns and to ensure that safety is not compromised in the pursuit of housing solutions.

As more states consider adopting single-staircase regulations, the ongoing debate between housing development and safety will likely continue. Future studies and legislative reviews will be crucial in determining the long-term impacts of these changes on both housing availability and resident safety.
