ADAAG Manual

Floor Plan of Elevator Cars [4.10.9]

The car dimensions specified in ADAAG are based on earlier accessibility guidelines developed in accord with industry standards. Alternate dimensions that provide wheelchair turning space (60 inch diameter circle or T-turn) wholly within the car are acceptable. Hospital-type cars sized to accommodate stretchers (usually at least 80 inches long) can have side-opening doors if the car is at least 60 inches wide. The primary test is whether a wheelchair user can enter the car, maneuver within reach of the controls, and exit. In alterations, smaller car sizes (minimum 47 inch width and 69 inch length) are permitted in cases of technical infeasibility, including where limited by existing shaft configurations (minimum car size is 48 by 48 inches). See ADAAG 4.1.6(3)(c).
