According to ADA guidelines, what is the minimum clear width required for an accessible doorway?
Correct Answer
B) 32 inches
ADA requires a minimum clear width of 32 inches for accessible doorways when the door is open 90 degrees. This provides adequate space for wheelchair passage.
Why This Is the Correct Answer
The ADA Standards for Accessible Design specifically require a minimum clear width of 32 inches for accessible doorways when measured with the door open at 90 degrees. This measurement is taken from the face of the door to the opposite door jamb or stop. The 32-inch clear width ensures adequate space for standard wheelchairs to pass through comfortably. This is a fundamental accessibility requirement that contractors must follow in all commercial construction and many residential applications.
Why the Other Options Are Wrong
Option A: 30 inches
30 inches is insufficient width for wheelchair accessibility and does not meet ADA minimum standards for clear doorway width.
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
Think '32 and free' - 32 inches gives wheelchair users the freedom to pass through doorways safely
