Vestibules

Vestibules must provide adequate maneuvering space for wheelchair users to navigate between door sets. The document includes detailed technical diagrams illustrating compliant vestibule configurations.

Door in Series Configuration

Layout: Doors swing in same direction

This configuration provides maneuvering space for wheelchair users when doors are aligned in sequence.

Both Doors Open Out (Serving Other Than a Required Exit Stairway)

Layout: Both doors open outward

Note: This configuration serves areas other than required exit stairways and provides additional space when door is equipped with both a latch and a closer.

Doors at Adjacent Walls

Layout: Doors positioned at 90-degree angle

This configuration allows wheelchair turning radius at corner vestibules.

Doors at Opposite Walls

Layout: Doors face each other

This configuration provides straight-through passage for wheelchair users.

Note: These diagrams illustrate the specific requirements of these regulations and are intended only as an aid for building design and construction.
