2016 California Standards for Accessible Design Pocket Guide - Eff. Jan. 1, 2017

 Advisory 11B-219.5 Permanent and portable systems.  The California Building Code (CBC) requires permanently installed assistive listening systems in those assembly areas where audible communication is integral to the use of a space (movie theaters, concert and lecture halls, playhouses, meeting rooms, etc.); where fixed seating is provided and where there may be an audio-amplification system. For other assembly areas, such as those without fixed seating, the CBC requires either a permanently installed system or a portable system. If a portable system is provided an adequate number of electrical outlets or other supplementary wiring to support the system is required. While this provision does not necessarily require the addition of electrical outlets, consideration should be given to locating outlets to support dispersion of seating available for individuals using the assistive listening systems. ◼
