2013 California Standards for Accessible Design Pocket Guide

ASSEMBLY AREA. [DSA-AC]  A building or facility, or portion thereof, used for the purpose of entertainment, educational or civic gatherings, or similar purposes. For the purposes of these requirements, assembly areas include, but are not limited to, classrooms, lecture halls, courtrooms, public meeting rooms, public hearing rooms, legislative chambers, motion picture houses, auditoria, theaters, playhouses, dinner theaters, concert halls, centers for the performing arts, amphitheaters, arenas, stadiums, grandstands, or convention centers.

Advisory Definition of ASSEMBLY AREA.  The application of the accessibility provisions of this code is based upon the use of the space rather than the occupancy classification. For example, an assembly area may or may not be a Group A Occupancy. A large conference room in a Group B Occupancy or a multi-purpose area in a Group E Occupancy may be an assembly area.◼
