A Wheelchair Ramp and the Law?

Answer 1

cific requirements for a wheelchair ramp are outlined in the Americans with Disabilities Act (ADA). Any passageway, or means of entry, with a slope greater that a 1:20 ratio is considered a ramp and must comply with these specifications.

The slope of any ramp should be the gentlest possible with the maximum being 1:12. The maximum height of a ramp between level areas should be 30 inches with a width of 36 inches. Each ramp must have a level landing, at least as wide as the ramp, and at least 60 inches in length, at its top and bottom. If a ramp changes direction at the landing, the landing must be at least a 60 inch square. A landing with a door must conform to additional space requirements based on the direction in which the door swings, hinge and latch positions.

Requirements for curb ramps being constructed at existing sites are somewhat different. They allow a slightly steeper slope if necessary

Every ramp higher than 6 inches or longer than 72 inches is required to have handrails on both sides. The handrails must have a width or diameter of 1 ¼ inches to 1 ½ inches, or the equivalent, and the space between the handrail and the wall must be 1 ½ inches. The handrails must be 34 to 38 inches high. Handrails intended for children’s use should be 28 inches high.

The gripping surfaces should be continuous for the length of the rail. The inside handrail of any ramp that turns at an angle must be continuous for the length of the ramp. The ends of any handrails not required to be continuous must extend at least 12 inches beyond the ramp segment and be parallel to the level surface. The ends must be either rounded or attached to a post or wall.

Ramps and landings with drop-offs must be protected by walls or curbs at least 2 inches high.

Ramp surfaces must conform to the general floor and ground specifications elsewhere in the law. Outdoor ramps must not allow for water buildup.
