The minimum width of at least one exterior egress door servicing a residence is often required to be how many inches?

• A. 32
• B. 30
• C. 36
• D. 42

Answer: (A)

The important idea is ensuring an exterior exit has enough opening width to allow safe egress, including for occupants who may need extra space. For a residence, at least one exterior door that serves as an egress must provide a minimum clear width of 32 inches when the door is opened to 90 degrees. This 32-inch figure is the actual usable width of the opening, not the rough door size, and it aligns with accessibility and safety requirements in many codes. A narrower width, like 30 inches, would not meet these egress standards, while wider openings such as 36 or 42 inches exceed the minimum.
