2019 California Standards for Accessible Design Guide (effective January 1, 2020 with July 1, 2021 amendments)
11B-225.2.3 Library book stacks.
Book stacks available for public use shall be 54 inches (1372 mm) maximum above the finish floor.
Exceptions:
- Book stacks available for public use may be higher than 54 inches (1372 mm) maximum above the finish floor when an attendant is available to assist persons with disabilities.
- Book stacks restricted to employee use are not required to comply with these requirements.
ETA Editor's Note
The ADA Advisory identifies library shelving as self-service shelving, which does not have a height limitation. Therefore, the height limitation imposed by CBC where no attendant is available is more restrictive. Otherwise, the storage requirements imposed by ADA are essentially identical to CBC. See also 11B-227.4 and 11B-904.5.1 pertaining to Self-Service Shelves and Dispensing Devices at Food Service Lines.
