What health inspectors found (on-site government inspections — the most independent evidence available)
Health inspection rating: ★★★★☆4/5 · CMS overall rating: 5/5
The health inspection star above is graded on a curve within each state — a set share of each state's facilities gets each star level — so a facility can have few citations and still rate 2–3 stars if others in its state did even better. The overall rating combines that inspection score with staffing and self-reported quality measures.
Most serious findings (actual harm or immediate jeopardy)
▲ Immediate jeopardy, repeated · Feb 17, 2023 · F-0801
The facility did not employ enough qualified food and nutrition staff, including a qualified dietician, to properly run its food service.
Why it matters: Without qualified nutrition staff, residents' special diets and nutritional needs may be handled incorrectly, risking weight loss and health decline.
Severity (K): A life-threatening or extremely dangerous situation affected several residents. Among the most serious findings an inspection can produce.

Nurse staffing (from payroll records, adjusted for how much care residents need)
| Measure | This facility | California avg | U.S. avg | Where it stands |
|---|---|---|---|---|
| Total nurse staffing (hours per resident per day) | 4.98 | 4.31 | 3.95 | top 15% in California; top 13% in the U.S. |
| Registered Nurse hours | 0.81 | 0.61 | 0.69 | top 17% in California; top 27% in the U.S. |
| Weekend total nurse staffing | 4.38 | 3.90 | 3.50 | top 18% in California; top 14% in the U.S. |
| Weekend RN hours (not acuity-adjusted) | 0.29 | 0.51 | 0.48 | bottom 31% in California; bottom 29% in the U.S. |
| Total nursing staff turnover (%) | 12.2 | 36.7 | 45.8 | top 1% in California; top 1% in the U.S. |
| RN turnover (%) | 16.7 | 38.1 | 42.9 | top 13% in California; top 9% in the U.S. |
Hours are per resident per day, case-mix adjusted by CMS so facilities caring for sicker residents can be compared fairly (same basis as the CMS staffing star). "Top X%" means better than most facilities: more staffing hours, or lower turnover. Raw (unadjusted) reported hours: total 4.22, RN 0.69, weekend 3.71. Staffing rating: 5/5.
Self-reported quality measures
Note: these ratings are based on data the facility reports about itself to CMS. They are not independently verified by inspectors, and can look better than inspection findings. Give more weight to the inspection results above.
Quality measures rating: 5/5 · long-stay residents: 5/5 · short-stay residents: —/5
