Facility Access Standards
These standards are based on the following:
- Americans With Disabilities Act
- ADA Accessibility Guidelines
- Section 508 of the Rehabilitation Act: Electronic and Information Technology Accessibility Standards
- 2001 California Building Code, California Code of Regulations, Title 24, Part 2, Vol.1
Paths of travel within facility
Doorways, including emergency exits, need a minimum of 32" clearance. Maneuvering clearance for wheelchair riders requires that the floor area around doorways be free and clear of obstructions.
Maneuvering clearance requires a minimum space of 60" diameter or a 60" by 60" T-shaped space off of an aisle for a pivoting 180-degree turn of a wheelchair rider. Service counter access requires that there must be at least a section that is at a height of 28" - 31" to work surface. Seating for wheelchair riders must be provided at counters, with knee spaces at least 27" high, 30" wide, and 19" deep.
Side aisles should be a minimum of 36" wide, and main aisles should be a minimum of 44" wide. For facilities set up with rows of multiple workstations, measure from the back of an empty chair, pushed in, to the surface edge of the next row of workstations.
There should be 30" by 48" clear floor space at all accessible workstations connected to an aisle. When seating for wheelchair riders is provided at tables or counters, knee spaces of at least 27" high, 30" wide, and 19" deep should be provided. The tops of accessible tables and counters should be from 28" to 31" above the finish floor or ground. If the clear floor space only allows forward approach to an object, the maximum high forward reach allowed should be 48". The minimum low forward reach is 15" (measurements are from the finished floor.)
Objects projecting from walls with their leading edges between 27" and 80" above the finished floor should protrude no more than 4" into walks, halls, corridors, passageways, or aisles. Objects mounted with their leading edges at or below 27" above the finished floor may protrude any amount.
A minimum of 1:20 workstations must be manually adjustable and allow for the measurements stated above under "workstation approach". Adjustable workstation chairs and footrests need to accompany the 1:20 adjustable workstations.
