Ramp Slopes

A ramp is comprised of horizontal sloped runs connected by level landings between runs. Any slope greater than 1:20 and less than 1:12 along an accessible route shall be considered a ramp that is required to comply with ADA accessibility codes and compliances. The least possible slope should be used whenever possible. The maximum allowable slope in any new construction is 1:12 with a maximum rise of 30” | 76.2 cm without a landing. A ramp with a slope between 1:12 and 1:16 can have a maximum horizontal length of 30’ | 9.14 m without a landing. A ramp with a slope between 1:16 and 1:20 can have a horizontal run up to 40’ | 12.19 m before requiring a landing.
