A detail drawing shows a bathroom door with a note stating '32" MIN CLR'. According to ADA requirements, what does this specification ensure?
Correct Answer
B) There is 32 inches minimum clear width when door is open 90 degrees
The '32" MIN CLR' specification ensures there is a minimum 32-inch clear width when the door is opened to 90 degrees, which is required by ADA for accessible passage through doorways.
Why This Is the Correct Answer
The '32" MIN CLR' notation specifically refers to the clear width opening when the door is in the open position at 90 degrees. This is a critical ADA requirement that ensures wheelchair users and people with mobility devices can pass through doorways safely. The clear width is measured from the face of the door when open to the opposite door jamb, accounting for the door thickness and hardware that reduces the actual passable space.
Why the Other Options Are Wrong
Option A: The door is 32 inches wide
This confuses the door width with clear width - a 32-inch wide door actually provides less than 32 inches of clear opening due to door thickness, hinges, and hardware taking up space in the opening.
Option C: The door frame is 32 inches clear height
The notation 'CLR' refers to clear width (horizontal measurement), not clear height (vertical measurement), and ADA door height requirements are separate from this specification.
Option D: 32 inches clearance is required on both sides of the door
The 32-inch requirement is for the clear width of the door opening itself, not for clearance space on both sides of the door, which has different ADA requirements for maneuvering space.
Memory Technique
CLR = Clear passage for wheelchair Roll-through (32 inches minimum when door is open)
