When fully opened, what is the maximum width reduction allowed for a door?

The maximum width reduction allowed for a door when fully opened is critical for ensuring accessibility and safety within buildings, especially in commercial contexts. A reduction of 7 inches is in line with standard building codes and regulations, which typically state that exit doors must provide a minimum clear width to facilitate safe egress. The reasoning behind this allowance is to strike a balance between the functionality of the door and safety protocols.

Having a maximum width reduction of 7 inches ensures that even when a door is partially obstructed or under pressure, it still allows sufficient space for individuals to pass through, which is particularly important in emergency situations. A reduction greater than this could compromise accessibility, especially for individuals with mobility challenges or those needing assistance.

Hence, 7 inches is established as the maximum acceptable reduction to maintain both functionality and safety within building design standards.
