According to the code, the minimum width of at least one egress (exterior) door servicing a residence is _____ inches

• A. 32
• B. 36
• C. 42
• D. 30

Answer: (A)

The main idea is that a dwelling must have an exterior egress door wide enough to let people exit safely in an emergency. Codes set a minimum net clear width for that opening to ensure people can pass through without getting stuck, including during quick evacuations or when someone is carrying items. The requirement is a minimum net clear width of 32 inches for at least one exterior door serving the residence. This 32-inch figure is the width of the opening when the door is open to 90 degrees, measured unobstructed (trim and hardware don’t reduce the clear width). If the opening is narrower than 32 inches, it wouldn’t meet the code. Doors wider than 32 inches, such as 36 inches, still comply and are commonly used, but they exceed the minimum rather than violate it. So, the correct concept is that the opening must be at least 32 inches wide to provide a safe and accessible egress path.
