When a pair of doors is provided, one of the doors must not be less than what width?

The requirement that one of the doors in a pair must be not less than a certain width relates to accessibility standards. Specifically, in building codes and accessibility guidelines, including the Americans with Disabilities Act (ADA), a minimum clear opening width is established to ensure that all individuals, including those using wheelchairs or mobility aids, can easily access passageways.

A door width of 36 inches is the correct specification because it allows for a clear opening that accommodates various mobility devices. This width ensures that people with disabilities can navigate through the doorway without difficulty, promoting inclusivity and compliance with accessibility regulations.

Narrower options, such as 30 or 32 inches, do not meet the ADA's recommendations for accessible routes, which is why they are not appropriate for ensuring adequate access. A door width of 40 inches, while it could also serve accessibility needs, is generally not a standard minimum requirement for pairs of doors, making 36 inches the most appropriate minimum width to meet both accessibility and practical usage standards.
