If you need to build a handicap accessible ramp to attach to your deck be aware that there are very specific rules that must be followed.First you must build the ramp at a 1:12 slope, which means that you can only drop 1â for every 12â of distance the ramp covers.ADA ramps that extend beyond 30â must have an intermediate landing.he ramp and platforms must be finished with a slip resistant surface. Ramps are usually framed with 2x12 stringers the same as stairs. Because ramps will usually terminate at the ground it may be necessary to bury a part of the frame to provide a smooth landing area.
