ADAAG Manual

Landings [4.8.4]

Landings at the top and bottom and intermediate landings, must be at least 60 inches long so maneuvering space is available for approaching ramps straight on. Landings must be at least as wide as the ramp they serve and cannot slope more than 2% in any direction. Where ramps change direction, the landing must be at least 60 by 60 inches. This applies to switchback ramps, ramps with a 90 degree turn, and angled ramps. Recommendation: Ramps and landings should be configured to facilitate maneuvering. For example, runs should be aligned along the outside landing edge, as in the case of ramps with a 90 degree turn, so that a wider turn is permitted. Handrail extensions can wrap around landings. It is recommended that landings of exterior ramps be drained so that water does not accumulate on the surface.
