An access control system may be deployed at a location in a multi-tenant environment. The access control system may store access control information at one or more of an access control device, an access control bridge device, or an access control server. Tenant-specific access control information may be respectively stored at tenant-specific access control devices to control access to tenant-specific areas of the location. Shared access control information may be stored at shared access control devices to control access to common areas of the location. The access control system may be selectively configured such that an access device, an access control bridge device, or the access control server processes requests for access that are received at the location.
