Additional sections of R404 address surfaces, size, knee and toe clearance, position, approach and maneuvering space. R404.2 provides specific information stating that surfaces are required to be firm, stable and slip resistant and free of surface level changes. They are allowed to have a running slope that is consistent with the grade of the adjacent pedestrian access route. Cross slope shall be 2 percent maximum.

The size of the clear space is required to be 2.5 ft x 4.0 ft minimum. The clear space can be positioned for either a forward or side reach, so directly in front of the pushbutton or off to one side. The side of the clear space has to adjoin the pedestrian access route or another clear space. If the clear space is confined on all or part of three sides, additional maneuvering space is required.
