11B-407 Elevators.
11B-407.1 General.
Elevators shall comply with Section 11B-407 and with ASME A17.1. They shall be passenger elevators as classified by ASME A17.1. Elevator operation shall be automatic.
[2010 ADAS] Advisory 407.1 General. The ADA and other Federal civil rights laws require that accessible features be maintained in working order so that they are accessible to and usable by those people they are intended to benefit. Building owners should note that the ASME Safety Code for Elevators and Escalators requires routine maintenance and inspections. Isolated or temporary interruptions in service due to maintenance or repairs may be unavoidable; however, failure to take prompt action to effect repairs could constitute a violation of Federal laws and these requirements.
DSA regulates the usability of elevators and platform (wheelchair) lifts for persons with disabilities. Accessibility scoping requirements for elevators and lifts are located in Sections 11B-206.6 and 11B-206.7; technical requirements are located in Sections 11B-407, 11B-408, 11B-409 and 11B-410.◼
