Section 1010.1/Doors, Gates, and Turnstiles

IBC 1010 covers egress door requirements including minimum width, swing direction, hardware, and operation requirements.

What this section requires

Egress doors must have a minimum clear width of 32 inches (measured between the face of the door and the stop with the door open 90 degrees). Door height must be at least 80 inches. Doors serving an occupant load of 50 or more or in Group H occupancies must swing in the direction of egress travel. Exit and exit access doors must be openable from the egress side without the use of a key, special knowledge, or effort.

Why this section exists

Doors are the most critical components in the egress path. A door that is too narrow creates a bottleneck during evacuation. A door that swings against the flow of egress can be pushed shut by crowd pressure. A door that requires a key or special knowledge to open traps occupants who are unfamiliar with the building. Every requirement in Section 1010 addresses a documented failure mode in fire evacuations.

What plan reviewers look for

Plan reviewers check door widths on the floor plan against the occupant load served. They verify swing direction for rooms with occupant loads of 50 or more. They check hardware specifications for panic hardware where required (Group A and E occupancies with occupant loads over 50, Group H). They also verify that doors in the means of egress are not equipped with locks that require keys from the egress side.

Common violations

Door swings against egress flow
A door serving a room with an occupant load over 50 swings into the room instead of in the direction of egress. This is one of the most common architectural plan review comments.
Clear width less than 32 inches
A door shown as 2'-8" (32 inches nominal) does not provide 32 inches of clear width when the door thickness, frame stop, and hardware are accounted for. A 3'-0" door is the minimum to reliably provide 32 inches clear.
Panic hardware not specified
An assembly or educational occupancy with more than 50 occupants does not specify panic hardware on the exit doors. Section 1010.1.10 requires panic hardware in these conditions.
Compliance tip
Annotate occupant loads on the floor plan at each door. Verify swing direction for every room with 50 or more occupants. Specify panic hardware in the door schedule for applicable occupancies. Use 3'-0" doors minimum in the means of egress to ensure 32 inches clear width.
