About this data: Every number on this page comes from the California Department of Social Services' Community Care Licensing Division (CCLD) public records, which ARFlookup.com refreshes weekly; last updated October 22, 2026. Stats cover the facilities currently operating (every status but Closed), except licensed beds, which count licensed facilities only. Citation totals are each facility's cumulative Type A and Type B citations; capacity is the licensed number of residents, not current occupancy. Always confirm with CCLD before making a decision.
