Most doors within a means of egress are required to be side-hinged or pivoted swinging doors, but there are specific exceptions in the model codes which define where sliding doors are allowed. Many of the accessibility requirements that apply to swinging doors also apply to sliding doors, although some of the requirements are slightly different for sliding doors vs. swinging doors. For example, the maneuvering clearance required for a sliding door is different from that required for a swinging door.
The ADA standards and ICC A117.1 both cover the accessibility requirements for manually-operated sliding doors that are part of an accessible route. These mandates include a maximum opening force, minimum clear opening width, required maneuvering clearance, and requirements pertaining to operable hardware.
