LANDING - RAMP - LANDING—There is a landing at the top and bottom of each ramp run. Landings and ramps are firm, stable, slip resistant, and 1 : 48 is their maximum cross slope. Where they differ is in their running slopes. 1 : 48 is a landing's maximum running slope. 1 : 12 is a ramp's maximum running slope. An accessible route with a running slope steeper than 1 : 20 is a ramp.

LANDING—Typical Guidelines: a. 36 inches (914 mm) is the minimum width. b. 60 inches (1524 mm) is the minimum depth. c. There is a landing at the top and bottom of each ramp. d. A landing is, at minimum, as wide as the widest ramp attached to it.

LANDING—Where Ramps Change Direction: a. 60 inches (1524 mm) is the minimum width. b. 60 inches (1524 mm) is the minimum depth. c. A landing has a maximum 1 : 48 cross slope and running slope. A 60 inch by 60 inch landing can be a turning space. Inside that minimum turning space, a 180 degree turn will require thought and care. Wherever space permits, minimum widths and depths should be increased in size. Note that the landings and ramps on the next page are wider than the minimum widths illustrated below.

RAMP IN NEW CONSTRUCTION—Typical Guidelines: a. 36 inches (914 mm) is the minimum width. b. 1 : 48 is the maximum cross slope. c. An accessible route with a running slope steeper than 1 : 20 is a ramp. d. 1 : 12 is the maximum running slope. e. Must have an accessible change in level. f. A ramp with a rise greater than 6 inches (152 mm) requires handrails. g. 30 inches (762 mm) is the maximum rise of a single ramp run. Note: In existing construction, when space limitations do not permit a 1 : 12 ramp, there are two exceptions. The exceptions are on pages 68 and 70.

RAMP IN NEW CONSTRUCTION—Running Slope: a. An accessible route with a running slope steeper than 1 : 20 is a ramp. b. 1 : 12 is the maximum running slope of a ramp in new construction.

RAMP IN NEW CONSTRUCTION—Cross Slope: 1 : 48 is the maximum cross slope of a ramp.

RAMP IN NEW CONSTRUCTION—Maximum Rise: a. 30 inches (762 mm) is the maximum rise of a single ramp run. b. A ramp with a rise greater than 6 inches (152 mm) requires handrails that comply with a locality's building standards. Four Components Make Up A Running Slope: a. A running slope has a two unit designation such as 1 : 12. 2. The first number is the vertical change in height, always 1 unit. c. The second number is the horizontal distance in like units. d. As the second number becomes larger, the slope becomes flatter. Example: 1 : 20 is a flatter slope than 1 : 12.

RAMP IN NEW CONSTRUCTION—Design Considerations: Ramp length is a consideration, especially for a building project with a tight budget. A long ramp with a rise of more than 6 inches (152 mm) will require handrails to facilitate the climb. There are ways to avoid the expense of handrails. One alternative is two short ramps with a landing in-between to break up the climb. A second alternative is a flatter, less tiring route with a running slope of 1 : 20 or less.

RAMP IN EXISTING CONSTRUCTION—Exception One: In existing construction, when space limitations do not permit a 1 : 12 ramp, a ramp with a 1 : 12 to 1 : 10 running slope is permitted provided its rise does not exceed 6 inches (152 mm).

RAMP IN EXISTING CONSTRUCTION—Exception One: In existing construction, when space limitations do not permit a 1 : 12 ramp, a ramp with a 1 : 12 to 1 : 10 running slope is permitted provided its rise does not exceed 6 inches (152 mm).

RAMP IN EXISTING CONSTRUCTION—Design Considerations: Because a ramp inside a home requires a significant length of unobstructed floor space, an interior route with a landing-ramp-landing combination is a major design decision. In all cases, 36 inches (914 mm) is the minimum width of a ramp. A landing must be as wide as the widest ramp attached to it, and 60 inches (1524 mm) is a landing's minimum depth.

RAMP IN EXISTING CONSTRUCTION—Exception Two: In existing construction, when space limitations do not permit a 1 : 12 ramp, a ramp with a 1 : 10 to 1 : 8 running slope is permitted provided its rise does not exceed 3 inches (76.2 mm). A ramp steeper t

RAMP IN EXISTING CONSTRUCTION—Exception Two: In existing construction, when space limitations do not permit a 1 : 12 ramp, a ramp with a 1 : 10 to 1 : 8 running slope is permitted provided its rise does not exceed 3 inches (76.2 mm). A ramp steeper than 1 : 8 is prohibited.
