36 CFR Parts 1190 and 1191 ADA and ABA Accessibility Guidelines - Preamble (Discussion of Comments and Changes)

The guidelines specify that LULA elevator cars be at least 42 inches wide and 54 inches deep with a door on the narrow end providing at least 32 inches clear width (408.4.1). In the final rule, the Board has added alternate dimensions which are substantively consistent with the latest edition of the ANSI A117.1 standard. These dimensions permit a car at least 51 inches by 51 inches provided that the door has a clear width of at least 36 inches (408.4.1, Exception 1).
