Doors and Gates in Series [§404.2.6]

At hinged or pivoted doors or gates in series, a separation is required that is at least 48” plus the width of doors or gates swinging into the space. This allows users to clear one door or gate before opening the next and applies to those doors or gates that are opposite each other where travel through both doors is required.

Recommendation:  Wheelchair space 30” min. by 48” min. beyond the swing of a door in other configurations, such as vestibules with doors on adjacent walls, will provide room to clear one door before opening the next.
