According to ADA requirements, what is the minimum clear width for an accessible door opening?
Correct Answer
B) 32 inches
ADA requires a minimum clear width of 32 inches for accessible door openings when the door is opened 90 degrees. This is measured from the face of the door to the 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 taken when the door is in the open position at 90 degrees, measured from the face of the door to the opposite stop. This 32-inch clear width ensures that individuals using wheelchairs, walkers, or other mobility devices can safely and comfortably pass through the doorway. This is a fundamental accessibility requirement that contractors must comply with in all commercial construction and many residential applications.
Why the Other Options Are Wrong
Option A: 30 inches
30 inches is insufficient width and does not meet ADA requirements, making it non-compliant for accessible design
Option C: 34 inches
34 inches exceeds the minimum requirement but is not the minimum standard specified by ADA
Option D: 36 inches
36 inches exceeds the minimum requirement but is not the minimum standard specified by ADA
Memory Technique
Think '32 and free' - 32 inches gives wheelchair users the freedom to pass through doorways safely
