What is the minimum clear width required for an accessible door opening under ADA guidelines?
Correct Answer
B) 32 inches
ADA requires a minimum clear width of 32 inches for accessible door openings. This measurement is taken with the door open at 90 degrees, measuring from the face of the door to the opposite stop.
Why This Is the Correct Answer
The ADA Standards for Accessible Design specifically requires a minimum clear width of 32 inches for accessible door openings. This measurement is critical for wheelchair accessibility and is taken with the door in the open position at 90 degrees. The clear width is measured from the face of the door to the opposite stop, not the rough opening or door frame width. This 32-inch requirement ensures adequate space for wheelchair users to navigate through doorways safely and independently.
Why the Other Options Are Wrong
Option A: 30 inches
30 inches is insufficient width for wheelchair accessibility and does not meet ADA requirements, as it would create barriers for users with mobility devices
Option C: 34 inches
34 inches exceeds the minimum requirement and while acceptable, it is not the minimum standard specified by ADA guidelines
Option D: 36 inches
36 inches exceeds the minimum requirement and while acceptable, it is not the minimum standard specified by ADA guidelines
Memory Technique
Remember '32 and free' - 32 inches minimum clear width allows wheelchair users to pass through freely
