2019 California Standards for Accessible Design Guide (effective January 1, 2020 with July 1, 2021 amendments)

11B-405.7 Landings.

Ramps shall have landings at the top and the bottom of each ramp run. Landings shall comply with Section 11B-405.7.

Advisory 11B-405.7 Landings. Ramps that do not have level landings at changes in direction can create a compound slope that will not meet the requirements of this chapter. Circular or curved ramps continually change direction. Curvilinear ramps with small radii also can create compound cross slopes and cannot, by their nature, meet the requirements for accessible routes. A level landing is needed at the accessible door to permit maneuvering and simultaneously door operation. ◼

(a) straight

(b) change in direction

(c) top landing

11B-405.7.1 Slope.

Landings shall comply with Section 11B-302. Changes in level, slopes exceeding 1:48, and detectable warnings shall not be permitted.

Exception: Reserved.

11B-405.7.2 Width.

The landing clear width shall be at least as wide as the widest ramp run leading to the landing.

11B-405.7.2.1.

Top landings shall be 60 inches (1524 mm) wide minimum.

Advisory 11B-405.7.2.1 Top landing width. Handrail extensions are not permitted to obstruct required clear landing dimensions except as allowed by the exception to Section 11B-307.2. Where the ramp width is less than the top landing width additional landing length may be necessary to accommodate handrail extensions required to be in the direction of the ramp run without diminishing the required clear landing length. Additional landing length may be provided across the entire landing width or as a level extension at the top of the ramp run. ◼

11B-405.7.3 Length.

The landing clear length shall be 60 inches (1524 mm) long minimum.

11B-405.7.3.1.

Bottom landings shall extend 72 inches (1829 mm) minimum in the direction of ramp run.

11B-405.7.4 Change in direction.

Ramps that change direction between runs at landings shall have a clear landing 60 inches (1525 mm) minimum by 72 inches (1829 mm) minimum in the direction of downward travel from the upper ramp run.

[2010 ADA Standards] 405.7.4 Change in Direction. Ramps that change direction between runs at landings shall have a clear landing 60 inches (1525 mm) minimum by 60 inches (1525 mm) minimum.

11B-405.7.5 Doorways.

Where doorways are located adjacent to a ramp landing, maneuvering clearances required by Sections 11B-404.2.4 and 11B-404.3.2 shall be permitted to overlap the required landing area. Doors, when fully open, shall not reduce the required ramp landing width by more than 3 inches (76 mm). Doors, in any position, shall not reduce the minimum dimension of the ramp landing to less than 42 inches (1067 mm).

[2010 ADA Standards] 405.7.5 Doorways. Where doorways are located adjacent to a ramp landing, maneuvering clearances required by 404.2.4 and 404.3.2 shall be permitted to overlap the required landing area.

Advisory 11B-405.7.5 Doors at ramp landings. Where a door swings onto a ramp landing width, additional ramp landing length as specified may be necessary to accommodate a clear level area for the wheelchair user to clear the door swing and not risk rolling backward down the ramp run. Where the ramp width is less than the landing width, additional ramp landing length may be provided as a level extension at the top of the ramp run, or the entire width of the landing. ◼
