California IDEX Practice Exam

According to the CBC, what is the minimum width of a stair when handrails are required on either side?

1. 36"

2. 38"

3. 42"

4. 44"

The correct answer is: 44"

The correct answer is based on the California Building Code (CBC) stipulations regarding the minimum width of stairs that require handrails on either side. According to the CBC, the minimum width for a stairway when handrails are required on both sides is 44 inches. This width ensures that there is sufficient space for two people to pass each other comfortably while also allowing for the safe installation of handrails, which are critical for providing support and preventing falls. Wider stairs enhance accessibility, particularly in public spaces where higher foot traffic might demand extra room for safety and convenience. The specification also incorporates safety standards that aim to accommodate emergency situations, allowing room for individuals to maneuver effectively. In contrast, widths that are less than 44 inches would not meet the regulatory requirements for handrails on both sides, which is important for ensuring the protection of individuals using the stairway. Thus, adherence to this minimum width is vital for maintaining safety standards set forth in the building code.
