Doors required to be accessible by 4.1 shall
comply with the requirements of 4.13.
4.13.2 Revolving Doors And
Revolving doors or turnstiles shall not be the only means of passage at an accessible
entrance or along an accessible route. An accessible gate or door shall be provided
adjacent to the turnstile or revolving door and shall be so designed as to facilitate the
same use pattern.
Gates, including ticket gates, shall meet all applicable specifications of 4.13.
4.13.4 Double-Leaf Doorways
If doorways have two independently operated door leaves, then at least one leaf
shall meet the specifications in 4.13.5 (width) and 4.13.6 (maneuvering clearances at doors). That leaf shall be
an active leaf.
4.13.5 Clear Width
Doorways shall have a minimum clear opening of 32 in (815 mm) with the
door open 90 degrees, measured between the face of the door and the opposite stop (see Fig. 24). Openings more than 24 in (610 mm) in
depth shall comply with 4.2.1 and 4.3.3 (see Fig. 24).
EXCEPTION: Doors not requiring full user passage, such as shallow closets, may have the
clear opening reduced to 20 in (510 mm) minimum.
4.13.6 Maneuvering Clearances At Doors
Minimum maneuvering clearances at doors that are not automatic or power-assisted shall be
as shown in Fig. 25(a) & Fig. 25(b) & Fig. 25(c). The floor or ground area
within the required clearances shall be level and clear.
EXCEPTION: Entry doors to acute care hospital bedrooms for in-patients shall be exempted
from the requirement for space at the latch side of the door (see dimension "x"
in Fig. 25) if the door is at least 44 in (1120 mm) wide.
4.13.7 Two Doors In Series
The minimum space between two hinged or pivoted doors in series shall be 48 in
(1220 mm) plus the width of any door swinging into the space. Doors in series shall swing
either in the same direction or away from the space between the doors (see Fig. 26).
4.13.8 Thresholds At Doorways
Thresholds at doorways shall not exceed 3/4 in (19 mm) in height for exterior sliding
doors or 1/2 in (13 mm) for other types of doors. Raised thresholds and floor level
changes at accessible doorways shall be beveled with a slope no greater than 1: 2 (see
Note: Thresholds and surface height changes in doorways are particularly inconvenient for
wheelchair users who also have low stamina or restrictions in arm movement because complex
maneuvering is required to get over the level change while operating the door.
4.13.9 Door Hardware
Handles, pulls, latches, locks, and other operating devices on accessible doors shall have
a shape that is easy to grasp with one hand and does not require tight grasping, tight
pinching, or twisting of the wrist to operate. Lever-operated mechanisms,
push-type mechanisms, and U-shaped handles are acceptable designs. When sliding
doors are fully open, operating hardware shall be exposed and usable from both sides.
Hardware required for accessible door passage shall be mounted no higher than 48
in (1220 mm) above finished floor.
Note: Some disabled persons must push against a door with their chair or walker to open
it. Applied kickplates on doors with closers can reduce required maintenance by
withstanding abuse from wheelchairs and canes. To be effective, they should cover the door
width, less approximately 2 in (51 mm), up to a height of 16 in (405 mm) from its bottom
edge and be centered across the width of the door.
4.13.10 Door Closers
If a door has a closer, then the sweep period of the closer shall be adjusted so that from
an open position of 70 degrees, the door will take at least 3 seconds to move to a point 3
in (75 mm) from the latch, measured to the leading edge of the door.
Note: Closers with delayed action features give a person more time to maneuver through
doorways. They are particularly useful on frequently used interior doors such as entrances
to toilet rooms.
4.13.11 Door Opening Force
The maximum force for pushing or pulling open a door shall be as follows:
- 4.13.11(1) Fire doors shall have the minimum opening force allowable by the appropriate
- 4.13.11(2) Other Doors
- Exterior hinged doors: (Reserved).
- 4.13.11(2)(b) Interior hinged doors: 5 lbf (22.2N)
- 4.13.11(2)(c) Sliding or folding doors: 5 lbf (22.2N)
These forces do not apply to the force required to retract latch bolts or disengage other
devices that may hold the door in a closed position.
Note: Although most people with disabilities can exert at least 5 lbf (22.2N), both
pushing and pulling from a stationary position, a few people with severe disabilities
cannot exert 3 lbf (13.13N). Although some people cannot manage the allowable forces in
this guideline and many others have difficulty, door closers must have certain minimum
closing forces to close doors satisfactorily. Forces for pushing or pulling doors open are
measured with a push-pull scale under the following conditions:
A4.13.11(1) Hinged Doors:
Force applied perpendicular to the door at the door opener or 30 in (760 mm) from the
hinged side, whichever is farther from the hinge.
A4.13.11(2) Sliding Or Folding Doors:
Force applied parallel to the door at the door pull or latch.
A4.13.11(3) Application Of Force:
Apply force gradually so that the applied force does not exceed the resistance of the
door. In high-rise buildings, air-pressure differentials may require a modification of
this specification in order to meet the functional intent.
4.13.12 Automatic Doors And
If an automatic door is used, then it shall comply with ANSI/BHMA A156.10-1985. Slowly
opening, low-powered, automatic doors shall comply with ANSI A156.19-1984. Such doors
shall not open to back check faster than 3 seconds and shall require no more than 15 lbf
(66.6N) to stop door movement. If a power-assisted door is used, its door-opening force
shall comply with 4.13.11 and its closing shall conform to the requirements in ANSI
Note: Sliding automatic doors do not need guard rails and are more convenient for
wheelchair users and visually impaired people to use. If slowly opening automatic doors
can be reactivated before their closing cycle is completed, they will be more convenient
in busy doorways.
