According to ADA requirements, what is the minimum clear width for an accessible doorway when the door is open 90 degrees?
Correct Answer
C) 32 inches
ADA requires a minimum clear opening width of 32 inches when the door is open 90 degrees. This typically requires a 36-inch door to achieve the 32-inch clear opening.
Why This Is the Correct Answer
The ADA Standards for Accessible Design specifically requires a minimum clear opening width of 32 inches when a door is open 90 degrees. This measurement is taken from the face of the door to the stop on the strike jamb when the door is fully open. The 32-inch clear width ensures adequate space for wheelchair users and people with mobility devices to pass through comfortably. This is a fundamental accessibility requirement that applies to most doorways in public accommodations and commercial facilities.
Why the Other Options Are Wrong
Option A: 30 inches
36 inches refers to the typical door width needed to achieve the 32-inch clear opening, not the clear opening width itself when the door is open 90 degrees.
Option B: 34 inches
30 inches is insufficient under ADA standards and would not provide adequate clearance for wheelchair users and mobility devices to pass through safely and comfortably.
Option D: 36 inches
34 inches exceeds the minimum requirement, and while it would be compliant, it is not the minimum standard specified by the ADA.
Memory Technique
Think '32 to get through' - 32 inches is the minimum clear width needed for accessibility compliance when doors are open.
