Cardinal Point at Mariner Square
What is a CCRC?
A Continuing Care Retirement Community (CCRC) offers multiple levels of care on a single campus — typically independent living, assisted living, and skilled nursing. Residents often enter under a long-term contract and can transition between care levels as their needs change. CCRCs in California are regulated by the California Department of Social Services.

Quick facts
Memory care context
Cardinal Point at Mariner Square is a California-licensed Residential Care Facility for the Elderly (RCFE) with 153 beds, operated by Cardinal Pt Mariner, Gallaher Sr Lvg, and Wellquest. The facility is designated as a Continuing Care Retirement Community (CCRC), but state licensing data does not confirm a dedicated memory-care designation. California Title 22 requires any RCFE accepting residents with dementia to meet standards under §87705 and §87706, including individualized care plans, staff training, and appropriate supervision. CDSS records show 10 inspection reports on file with one Type B deficiency (potential for harm) and zero Type A deficiencies (actual harm). Three complaints have been investigated during the inspection period. The most recent inspection occurred on February 13, 2026.
Questions to ask on your tour
Based on Cardinal Point at Mariner Square's state inspection record.
State licensing data does not confirm a memory-care designation for this 153-bed CCRC — does the facility currently accept residents with dementia, and if so, which building or unit provides that care?
The inspection history shows one Type B deficiency — what was the specific Title 22 section cited, and what corrective action was taken?
Three complaints were filed with CDSS during the inspection period on file — what were the subjects of those complaints, and which were substantiated?
If you accept dementia residents, how do you document compliance with California Title 22 §87705 requirements for dementia-specific staff training?
With three operators listed on the license (Cardinal Pt Mariner, Gallaher Sr Lvg, Wellquest), who has day-to-day responsibility for resident care decisions and regulatory compliance?
