SECTION 1133B

GENERAL ACCESSIBILITY FOR ENTRANCES, EXITS AND PATHS OF TRAVEL

1133B.2 Doors.

1133B.2.3.2 Automatic and power-assisted doors.  If an automatic door is used, then it shall comply with BHMA A156.10. Slowly opening, low-powered, automatic doors shall comply with BHMA A156.19. Such doors shall not open to back check faster than 3 seconds andshall require no more than 15 Ibf (66.72 N) to stop door movement. If a power-assisted door is used, its door-opening force shall comply with Section 1133B.2.5and its closing shall conform to the requirements in BHMA A156.19. When an automatic door operator is utilized to operate a pair of doors, at least one of the doors shall provide a clear, unobstructed opening width of 32 inches (813 mm) with the door positioned at an angle of 90 degrees from its closed position.

Exceptions:

1.      The provisions of Section 1133B.2.3 shall not apply to existing buildings, except when otherwise required under conditions applicable to access for persons with disabilities. In existing buildings, the following shall apply:

Where the occupant load is less than 10, except Group I, Division 1 occupancies, or where the occupant load is greater than 10 and it is determined that compliance with Section 1133B.2.3 would create an unreasonable hardship, a projection of 5/8 inch (16 mm) maximum will be permitted for the latch side stop.

2.      In existing buildings, the provisions of this section shall not apply when legal or physical constraints will not allow compliance with these building standards or equivalent facilitation without creating an unreasonable hardship. See Section 1.9.1.5.

ETA Editor's Note

The requirements of 2010 CBC 1133B.2.3.2 are similar to those of 1991 ADAAG 4.13.12.  The requirements of 2013 CBC 11B-404.3 are similar to 2010 ADAS 404.3, except more stringent regarding leaf width.  The newer regulations are clearly more stringent regarding electrical power and substitution of powered doors for required maneuvering clearances.
