2022 California Standards for Accessible Design Guide (effective January 1, 2023)
DIVISION 4: ACCESSIBLE ROUTES
11B-401.1 Scope.
The provisions of Division 4 shall apply where required by Division 2 or where referenced by a requirement in this chapter.
11B-402.2 Components.
Accessible routes shall consist of one or more of the following components: walking surfaces with a running slope not steeper than 1:20, doorways, ramps, curb ramps excluding the flared sides, elevators, and platform lifts. All components of an accessible route shall comply with the applicable requirements of Division 4.
11B-403.1 General.
Walking surfaces that are a part of an accessible route shall comply with Section 11B-403.
11B-403.2 Floor or ground surface.
Floor or ground surfaces shall comply with Section 11B-302.
11B-403.3 Slope.
The running slope of walking surfaces shall not be steeper than 1:20. The cross slope of walking surfaces shall not be steeper than 1:48.
Exception: The running slope of sidewalks shall not exceed the general grade established for the adjacent street or highway.
When the running slope of a walking surface exceeds 5%, it must comply with the accessibility requirements for ramps.
A sloping sidewalk with a running slope in excess of 5% is excluded from ramp requirements for landings and handrails but it must comply with cross-slope and width requirements. ◼
ETA Editor's Note
The 2022 CBC Exception at 11B-403.3 is not present in the 2010 ADA Standards. Therefore, technically, the 2010 ADA Standards are more stringent with regard to the slope of sidewalks at streets or highways. CBC does not define street or highway but does define sidewalk as " ... contiguous to a street used by the public." It is inferable, whether intended or not, that sidewalks serving as accessible routes alongside private roadways are not excepted from the slope limitation.
On August 8, 2023, the U.S. Access Board published in the Federal Register its final rule on accessibility guidelines for pedestrian facilities in the public right-of-way. More information may be found on the Access Board's website: U.S. Access Board Issues Final Rule on Public Right-of-Way Accessibility Guidelines (access-board.gov).
In 2013, in response to feedback, the U.S. Access Board issued a proposed Supplemental Rule to address accessibility for Shared Use Paths (used by pedestrians, bicyclists, and others for transportation or recreation), distinguished from sidewalks, as well as from trails. More information about this rulemaking process is available on the Access Board’s website: https://www.access-board.gov/guidelines-and-standards/streets-sidewalks/shared-use-paths.
11B-403.4 Changes in level.
Changes in level shall comply with Section 11B-303.
11B-403.5 Clearances.
Walking surfaces shall provide clearances complying with Section 11B-403.5.
Exception: Within employee work areas, clearances on common use circulation paths shall be permitted to be decreased by work area equipment provided that the decrease is essential to the function of the work being performed.
11B-403.5.1 Clear width.
Except as provided in Sections 11B-403.5.2 and 11B-403.5.3, the clear width of walking surfaces shall be 36 inches (914 mm) minimum.
Exceptions:
- The clear width shall be permitted to be reduced to 32 inches (813 mm) minimum for a length of 24 inches (610 mm) maximum provided that reduced width segments are separated by segments that are 48 inches (1219 mm) long minimum and 36 inches (914 mm) wide minimum.
- The clear width for walking surfaces in corridors serving an occupant load of 10 or more shall be 44 inches (1118 mm) minimum.
- The clear width for sidewalks and walks shall be 48 inches (1219 mm) minimum. When, because of right-of-way restrictions, natural barriers or other existing conditions, the enforcing agency determines that compliance with the 48-inch (1219 mm) clear sidewalk width would create an unreasonable hardship, the clear width may be reduced to 36 inches (914 mm).
- The clear width for aisles shall be 36 inches (914 mm) minimum if serving elements on only one side, and 44 inches (1118 mm) minimum if serving elements on both sides.
- The clear width for accessible routes to accessible toilet compartments shall be 44 inches (1118 mm) except for door-opening widths and door swings.
ETA Editor's Note
CBC Exceptions 2, 3 and 4 at 11B-403.5.1 are not present in the 2010 ADA Standards. Therefore, CBC requirements related to the clear width of accessible routes are more stringent.
FIGURE 11B-403.5.1 CLEAR WIDTH OF AN ACCESSIBLE ROUTE
11B-403.5.2 Clear width at turn.
Where the accessible route makes a 180 degree turn around an element which is less than 48 inches (1219 mm) wide, clear width shall be 42 inches (1067 mm) minimum approaching the turn, 48 inches (1219 mm) minimum at the turn and 42 inches (1067 mm) minimum leaving the turn.
Exception: Where the clear width at the turn is 60 inches (1524 mm) minimum compliance with Section 11B-403.5.2 shall not be required.
FIGURE 11B-403.5.2 CLEAR WIDTH AT TURN
11B-403.5.3 Passing spaces.
An accessible route with a clear width less than 60 inches (1524 mm) shall provide passing spaces at intervals of 200 feet (60,960 mm) maximum. Passing spaces shall be either: a space 60 inches (1524 mm) minimum by 60 inches (1524 mm) minimum; or, an intersection of two walking surfaces providing a T-shaped space complying with Section 11B-304.3.2 where the base and arms of the T-shaped space extend 48 inches (1219 mm) minimum beyond the intersection.
11B-403.6 Handrails.
Where handrails are provided along walking surfaces with running slopes not steeper than 1:20 they shall comply with Section 11B-505.
11B-403.7 Continuous gradient.
All walks with continuous gradients shall have resting areas, 60 inches (1524 mm) in length, at intervals of 400 feet (121,920 mm) maximum. The resting area shall be at least as wide as the walk. The slope of the resting area in all directions shall be 1:48 maximum.
ETA Editor's Note
CBC requirement 11B-403.7 is not present in the 2010 ADA Standards. Therefore, CBC requirements related to continuous gradients are more stringent.
11B-404.1 General.
Doors, doorways, and gates that are part of an accessible route shall comply with Section 11B-404.
Exceptions:
- Doors, doorways, and gates designed to be operated only by security personnel shall not be required to comply with Sections 11B-404.2.7, 11B-404.2.8, 11B-404.2.9, 11B-404.3.2 and 11B-404.3.4 through 11B-404.3.7. A sign visible from the approach side complying with Section 11B-703.5 shall be posted stating “Entry restricted and controlled by security personnel”.
- At detention and correctional facilities, doors, doorways, and gates designed to be operated only by security personnel shall not be required to comply with Sections 11B-404.2.7, 11B-404.2.8, 11B-404.2.9, 11B-404.3.2 and 11B-404.3.4 through 11B-404.3.7.

The force for pushing or pulling open a door or gate shall be as follows:
[2010 ADA Standards] 404.2.9 Door and Gate Opening Force. Fire doors shall have a minimum opening force allowable by the appropriate Administrative Authority. The force for pushing or pulling open a door or gate other than fire doors shall be as follows:
- Interior hinged doors and gates: 5 pounds (22.2 N) maximum.
- Sliding or folding doors: 5 pounds (22 N) maximum.
- Required fire doors: the minimum opening force allowable by the appropriate administrative authority, not to exceed 15 pounds (66.7 N).
- Exterior hinged doors: 5 pounds (22.2 N) maximum.
ETA Editor's Note
The CBC limitation for opening force at non-rated exterior doors is more stringent than the 2010 ADA Standards, and can be difficult to meet without a powered device at exterior doors exposed to wind, or leading from spaces that operate at negative pressure with respect to the exterior environment. That is the principal reason for the preceding Exception to 11B-404.2.9 that does not appear in the 2010 ADA Standards.
These forces do not apply to the force required to retract latch bolts or disengage other devices that hold the door or gate in a closed position.
Exception: When, at a single location, one of every eight exterior door leafs, or fraction of eight, is a powered door, other exterior doors at the same location, serving the same interior space, may have a maximum opening force of 8.5 pounds (37.8 N). The powered leaf(s) shall be located closest to the accessible route.
a. Powered doors shall comply with Section 11B-404.3. Powered doors shall be fully automatic doors complying with Builders Hardware Manufacturers’ Association (BHMA) A156.10 or low energy operated doors complying with BHMA A156.19.
b. Powered doors serving a building or facility with an occupancy of 150 or more shall be provided with a back-up battery or back-up generator. The back-up power source shall be able to cycle the door a minimum of 100 cycles.
c. Powered doors shall be controlled on both the interior and exterior sides of the doors by sensing devices, push plates, vertical actuation bars or other similar operating devices complying with Section 11B-309.
At each location where push plates are provided there shall be two push plates; the centerline of one push plate shall be 7 inches (178 mm) minimum and 8 inches (203 mm) maximum above the floor or ground surface and the centerline of the second push plate shall be 30 inches (762 mm) minimum and 44 inches (1118 mm) maximum above the floor or ground surface. Each push plate shall be a minimum of 4 inches (102 mm) diameter or a minimum of 4 inches by 4 inches (102 mm by 102 mm) square and shall display the International Symbol of Accessibility complying with Section 11B-703.7.
At each location where vertical actuation bars are provided the operable portion shall be located so the bottom is 5 inches (127 mm) maximum above the floor or ground surface and the top is 35 inches (889 mm) minimum above the floor or ground surface. The operable portion of each vertical actuation bar shall be a minimum of 2 inches (51 mm) wide and shall display the International Symbol of Accessibility complying with Section 11B-703.7.
Where push plates, vertical actuation bars or other similar operating devices are provided, they shall be placed in a conspicuous location. A level and clear floor or ground space for forward or parallel approach complying with Section 11B-305 shall be provided, centered on the operating device. Doors shall not swing into the required clear floor or ground space.
d. Signs identifying the accessible entrance required by Section 11B-216.6 shall be placed on, or immediately adjacent to, each powered door. Signs shall be provided in compliance with BHMA A156.10 or BHMA 156.19, as applicable.
e. In addition to the requirements of Item d, where a powered door is provided in buildings or facilities containing assembly occupancies of 300 or more, a sign displaying the International Symbol of Accessibility measuring 6 inches by 6 inches (152 mm by 152 mm), complying with Section 11B-703.7, shall be provided above the door on both the interior and exterior sides of each powered door.
11B-404.2.10 Door and gate surfaces.
Swinging door and gate surfaces within 10 inches (254 mm) of the finish floor or ground measured vertically shall have a smooth surface on the push side extending the full width of the door or gate. Parts creating horizontal or vertical joints in these surfaces shall be within 1/16 inch (1.6 mm) of the same plane as the other and be free of sharp or abrasive edges. Cavities created by added kick plates shall be capped.
Exceptions:
- Sliding doors shall not be required to comply with Section 11B-404.2.10.
- Tempered glass doors without stiles and having a bottom rail or shoe with the top leading edge tapered at 60 degrees minimum from the horizontal shall not be required to meet the 10 inch (254 mm) bottom smooth surface height requirement.
- Doors and gates that do not extend to within 10 inches (254 mm) of the finish floor or ground shall not be required to comply with Section 11B-404.2.10.
- Reserved.
[2010 ADA Standards] 4. Existing doors and gates without smooth surfaces within 10 inches (255 mm) of the finish floor or ground shall not be required to provide smooth surfaces complying with 404.2.10 provided that if added kick plates are installed, cavities created by such kick plates are capped.
ETA Editor's Note
Lacking Exception 4 at 11B-404.2.10, CBC is more stringent at existing doors than 2010 ADA Standards.
11B-404.2.11 Vision lights.
Doors, gates, and side lights adjacent to doors or gates, containing one or more glazing panels that permit viewing through the panels shall have the bottom of at least one glazed panel located 43 inches (1092 mm) maximum above the finish floor.
Exception: Glazing panels with the lowest part more than 66 inches (1676 mm) from the finish floor or ground shall not be required to comply with Section 11B-404.2.11.
ETA Editor's Note
The vision light requirement of CBC 11B-404.2.11 is derived from the 2010 ADA Standards 404.2.11. Under ADA, an existing door with a noncompliant vision light is a Safe Harbored element for path of travel and barrier removal purposes but will have to comply when the door is replaced, and may not be relocated elsewhere on an accessible route. Under CBC, an existing primary entrance door with a noncompliant vision light is not Safe Harbored, unless the Exception at 11B-404.2.11 applies, and must be mitigated under path of travel obligations.
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.
11B-405.1 General.
Ramps on accessible routes shall comply with Section 11B-405.
Exception: In assembly areas, aisle ramps adjacent to seating and not serving elements required to be on an accessible route shall not be required to comply with Section 11B-405.
11B-405.2 Slope.
Ramp runs shall have a running slope not steeper than 1:12.
Exception: Reserved.
[2010 ADA Standards] EXCEPTION: In existing sites, buildings, and facilities, ramps shall be permitted to have running slopes steeper than 1:12 complying with Table 405.2 where such slopes are necessary due to space limitations.
Table 405.2 Maximum Ramp Slope and Rise for Existing Sites, Buildings, and Facilities
Slope1 |
Maximum Rise |
---|---|
Steeper than 1:10 but |
3 inches (75 mm) |
Steeper than 1:12 but |
6 inches (150 mm) |
1. A slope steeper than 1:8 is prohibited.
ETA Editor's Note
Lacking the Exception at 11B-405.2, CBC is more stringent at existing ramps than 2010 ADA Standards.
11B-405.3 Cross slope.
Cross slope of ramp runs shall not be steeper than 1:48.
11B-405.4 Floor or ground surfaces.
Floor or ground surfaces of ramp runs shall comply with Section 11B-302. Changes in level other than the running slope and cross slope are not permitted on ramp runs.
11B-405.5 Clear width.
