2022 California Standards for Accessible Design Guide (effective January 1, 2023 with July 1, 2024 amendments)

11B-108 Maintenance of accessible features. Features for accessibility must be permanently functional, unobstructed and may not be removed. It is not sufficient to provide features such as accessible routes, parking, elevators, ramps or signage if those features are not maintained in a manner that enables individuals with disabilities to use them. Inoperable elevators, locked accessible doors, or "accessible" routes that are obstructed by furniture, filing cabinets or potted plants are not accessible to nor usable by persons with disabilities. ◼
