2022 California Standards for Accessible Design Guide (effective January 1, 2023)
11B-404.3 Automatic and power-assisted doors and gates.
Automatic doors and automatic gates shall comply with Section 11B-404.3. Full-powered automatic doors shall comply with ANSI/BHMA A156.10. Low-energy and power-assisted doors shall comply with ANSI/BHMA A156.19.
11B-404.3.1 Clear width.
Doorways shall provide a clear opening of 32 inches (813 mm) minimum in power-on and power-off mode. The minimum clear width for automatic door systems in a doorway shall provide a clear, unobstructed opening of 32 inches (813 mm) with one leaf positioned at an angle of 90 degrees from its closed position.
[2010 ADA Standards] 404.3.1 Clear Width. Doorways shall provide a clear opening of 32 inches (815 mm) minimum in power-on and power-off mode. The minimum clear width for automatic door systems in a doorway shall be based on the clear opening provided by all leaves in the open position.
ETA Editor's Note
CBC clear width requirement is more stringent at multi-leaf automatic and power-assisted doors than 2010 ADA Standards, since it must be provided by one door leaf.
11B-404.3.2 Maneuvering clearance.
Clearances at power-assisted doors and gates shall comply with Section 11B-404.2.4. Clearances at automatic doors and gates without standby power and serving an accessible means of egress shall comply with Section 11B-404.2.4.
Exception: Where automatic doors and gates remain open in the power-off condition, compliance with Section 11B-404.2.4 shall not be required.
ETA Editor's Note
The implication of 11B-404.3.2 is that power-assist devices (ANSI/BHMA A156.19) cannot substitute for required door maneuvering clearances, even if standby power is provided. Automatic door operators (ANSI/BHMA A156.10) can substitute for required door maneuvering clearances under one of the following conditions: a) standby power is provided; or, b) the door or gate remains open during power failure or cessation. See also DSA Advisory 11B-404.3.
11B-404.3.3 Thresholds.
Thresholds and changes in level at doorways shall comply with Section 11B-404.2.5.
11B-404.3.4 Doors in series and gates in series.
Doors in series and gates in series shall comply with Section 11B-404.2.6.
11B-404.3.5 Controls.
Manually operated controls shall comply with Section 11B-309. The clear floor space adjacent to the control shall be located beyond the arc of the door swing.
11B-404.3.6 Break out opening.
Where doors and gates without standby power are a part of a means of egress, the clear break out opening at swinging or sliding doors and gates shall be 32 inches (813 mm) minimum when operated in emergency mode.
Exception: Where manual swinging doors and gates comply with Section 11B-404.2 and serve the same means of egress compliance with Section 11B-404.3.6 shall not be required.
11B-404.3.7 Revolving doors, revolving gates, and turnstiles.
Revolving doors, revolving gates, and turnstiles shall not be part of an accessible route.
