2013 California Standards for Accessible Design Pocket Guide

Advisory 11B-206.2.6 Performance areas.  Performance areas, including but not limited to, stages, platforms and orchestra pits, are treated as raised or lowered areas within a given story and all are required to be accessible by ramp, elevator or, when allowed, by platform lift. In compliance with Section 11B-206.7.1, wheelchair lifts may be used to access stages, platforms and orchestra pits used as performing areas. These areas are required to be accessible whether temporary or not. 

Generally, the accessible route to the stage shall coincide with the route for the general public per Section 11B-206.3, to the maximum extent feasible.  For example, requiring persons with disabilities to go outside the building and reenter the building to gain access the stage when others have a direct route would not be considered coinciding. ◼
