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

 Advisory 11B-221.1 General.  Several different types of accessible seating are required in an assembly seating area.

Wheelchair seating areas, integrated into the general seating plan, are required so that people using wheelchairs are not isolated from other spectators or their friends and family. These seating areas must comply with Section 11B-221.2.

Companion seats are required next to each wheelchair seating location. The companion seat is a conventional seat that accommodates a friend or companion. These seats must comply with Section 11B-221.3.

Aisle seating is required to be provided in addition to the wheelchair seating areas. At least five percent of aisle seats (but not less than one) are required to either have no armrest on the aisle side or to have a removable or folding armrest on the aisle side. These seats accommodate people who have a mobility disability but who wish to use a seat that is not in a wheelchair seating location. These seats must comply with Section 11B-221.4.

Semi-ambulant seating is required in addition to the spaces provided for wheelchair users.  At least one percent of all seats (but no fewer than two) are required to provide 24 inches clear leg room from the front edge of the seat to the nearest obstruction or to the back of the seat immediately in front. These seats accommodate people who have a mobility disability but who wish to use a seat that is not in a wheelchair seating location.  These seats must comply with Section 11B-221.6. ◼
