What minimum clear width does the Federal Housing Administration (FHA) regulations permit for a main stairway?

The Federal Housing Administration (FHA) sets specific standards for home construction to ensure safety and accessibility, particularly in areas such as stairways. The minimum clear width permitted for a main stairway under FHA regulations is 2 feet 8 inches. This dimension is important because it helps accommodate the passage of individuals, including those using mobility aids or who need assistance, ensuring that stairways are safe and accessible for everyone.

A clear width of less than 2 feet 8 inches could result in difficulties for users navigating the stairs, especially in emergency situations. Therefore, adhering to the FHA standard of 2 feet 8 inches helps ensure regulatory compliance and promotes safety and usability in residential buildings.
