California Building Standards
While they’ve adopted the format of the ADA, the State of California relies on the California Building Code to outline their compliance laws. This means that the requirements for assistive listening systems in California are a little different. You can find the requirements listen under sections 11B-219 and 11B-706 in the CBC, which gets updated every three years.
