H.R. 9564, the Military Housing Innovation Act, requires the Comptroller General to conduct a comprehensive study on whether the Defense Department should allow "point-access block design" in military housing construction projects. Point-access block design refers to residential buildings up to six stories tall where a single internal stairway provides access to all units, a construction method that could potentially reduce building costs and increase affordable housing options near military installations. The study, due within 18 months and conducted in coordination with the Department of Defense, Department of Housing and Urban Development, and the National Institute of Standards and Technology, will examine how adopting this design approach would affect construction costs, housing quality and availability, fire safety outcomes, and the rental housing market around military bases. The Comptroller General will deliver a final report within two years that includes recommendations on whether the Defense Department should update its building codes to allow this construction method for military family housing and unaccompanied housing projects. The legislation aims to explore ways to improve the affordability and feasibility of building new military housing while maintaining safety standards.
