Accessibility design criteria illustrating wheelchair clearances and knee space dimensions for built-in counters and lavatories. The elevation and plan views detail a minimum 27-inch high knee clearance, a minimum 9-inch high toe clearance, and specific depth and width requirements. Configuration A and C show vertical clearances with 27 inches and 29 inches minimum to the underside, while the plan view indicates a maximum 25-inch depth and 30-inch minimum width. Side clearances require an 8-inch minimum reach and an 11-inch minimum toe and knee depth at the floor level.
