Clear floor space and turning space

Chapter 3: Building Blocks Clear Floor or Ground Space and Turning Space Knee and Toe Space Depth Where knee and toe space is required, it must be at least 17” deep. In all cases, the minimum depth may be further determined by the required reach to operable parts served by the clear floor space. Knee and toe space is required below drinking fountains, lavatories and sinks, dining and work surfaces, and those sales and service counters that provide a forward approach. 17” min Obstructed Reach Depth At any element, the knee and toe space must be as deep as the required reach to X (25” max) operable parts. This facilitates access since a forward reach does not extend far beyond the toes. Both the reach depth and the knee and toe space depth are limited to 25” measured from the leading edge of obstructions. Space beyond this depth is not usable. ≥ X (25” max) max) 5
