What health inspectors found (on-site government inspections — the most independent evidence available)

Health inspection rating: ★★★★☆4/5 · CMS overall rating: 4/5

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.

All citations in the current public record (30)

CMS publishes roughly the last three inspection cycles plus recent complaint investigations. Older surveys drop out of the record as new ones are completed.

Date	Severity	What the facility was cited for
Sep 18, 2025	F · Potential for harm, facility-wide	The facility did not have a registered nurse on duty at least 8 hours a day, or did not have a registered nurse serving full-time as director of nursing.
Sep 18, 2025	D · Potential for harm, one-off	The facility did not provide proper care for pressure ulcers (bedsores) or did not do enough to prevent new ones from forming. Bedsores develop when residents stay in one position too long without help moving.
Sep 18, 2025	D · Potential for harm, one-off	The facility did not keep the environment free of accident hazards, or did not provide enough supervision to prevent accidents like falls.
Sep 18, 2025	D · Potential for harm, one-off	The facility did not provide pharmacy services that meet each resident's needs, or did not employ or contract with a licensed pharmacist.
Sep 18, 2025	D · Potential for harm, one-off	The facility's medication error rate was 5 percent or higher — meaning too many doses were given incorrectly, such as the wrong drug, dose, or time.
Sep 18, 2025	D · Potential for harm, one-off	The facility did not label drugs according to professional standards or did not store them in locked compartments, with controlled drugs (medications with a high risk of misuse) kept under a separate lock.
Sep 18, 2025	D · Potential for harm, one-off	The facility did not have or follow an effective program to prevent and control infections — such as proper hand washing, cleaning, and isolation practices. This is the most commonly cited deficiency nationwide.
Mar 18, 2025	D · Potential for harm, one-off	The facility did not provide the help residents need with basic daily activities — like bathing, dressing, eating, and using the bathroom — for residents who cannot do these things on their own. · from a complaint
Aug 9, 2024	F · Potential for harm, facility-wide	The facility's menus did not meet residents' nutritional needs, or were not prepared in advance, followed as written, kept up to date, or reviewed by a dietician.
Aug 9, 2024	F · Potential for harm, facility-wide	The facility did not get its food from approved, safe sources, or did not store, prepare, and serve food according to professional food safety standards.
Aug 9, 2024	E · Potential for harm, repeated	The facility did not prepare and serve food in a form that meets each resident's individual needs — for example, chopped, pureed, or softened food for residents with chewing or swallowing problems.
Aug 9, 2024	D · Potential for harm, one-off	The facility did not enter each resident's assessment information into the required format and send it to the state within 7 days of completing the assessment, as the rules require.
Aug 9, 2024	D · Potential for harm, one-off	The facility did not provide enough food and fluids to keep residents healthy, such as preventing unplanned weight loss or dehydration.
Aug 9, 2024	D · Potential for harm, one-off	The facility did not make sure its nurses and nurse aides had the skills and training needed to properly care for every resident.
Aug 9, 2024	D · Potential for harm, one-off	The facility did not provide pharmacy services that meet each resident's needs, or did not employ or contract with a licensed pharmacist.
Aug 9, 2024	D · Potential for harm, one-off	The facility did not label drugs according to professional standards or did not store them in locked compartments, with controlled drugs (medications with a high risk of misuse) kept under a separate lock.
Nov 14, 2023	D · Potential for harm, one-off	The facility did not allow a resident's chosen representative — often a family member or someone with power of attorney — to exercise the resident's rights on their behalf. When a resident can't speak for themselves, their representative steps into that role. · from a complaint
Sep 21, 2023	D · Potential for harm, one-off	The facility did not keep the environment free of accident hazards, or did not provide enough supervision to prevent accidents like falls. · from a complaint
Aug 31, 2023	D · Potential for harm, one-off	The facility did not provide treatment and care that follows the doctor's orders and matches the resident's own preferences and goals. · from a complaint
Jun 29, 2023	F · Potential for harm, facility-wide	The facility did not get its food from approved, safe sources, or did not store, prepare, and serve food according to professional food safety standards.
Jun 29, 2023	F · Potential for harm, facility-wide	The facility did not have or follow an effective program to prevent and control infections — such as proper hand washing, cleaning, and isolation practices. This is the most commonly cited deficiency nationwide.
Jun 29, 2023	E · Potential for harm, repeated	The facility did not provide treatment and care that follows the doctor's orders and matches the resident's own preferences and goals.
Jun 29, 2023	D · Potential for harm, one-off	The facility did not keep residents' personal and medical information private and confidential.
Jun 29, 2023	D · Potential for harm, one-off	The facility did not accurately assess a resident's health and needs. Assessments are the foundation for all the care a resident receives.
Jun 29, 2023	D · Potential for harm, one-off	The facility did not properly complete the required screening (called PASARR) that identifies whether a person entering a nursing home has a mental illness or intellectual disability and needs specialized services.
Jun 29, 2023	D · Potential for harm, one-off	The facility did not label drugs according to professional standards or did not store them in locked compartments, with controlled drugs (medications with a high risk of misuse) kept under a separate lock.
Jun 29, 2023	D · Potential for harm, one-off	The facility did not employ enough qualified food and nutrition staff, including a qualified dietician, to properly run its food service.
Jun 29, 2023	D · Potential for harm, one-off	The facility did not serve food and drinks that were appetizing, attractive, and at a safe and pleasant temperature.
Jun 29, 2023	D · Potential for harm, one-off	The facility did not have a working program to monitor how antibiotics are used. Tracking antibiotic use helps make sure these drugs are given only when needed and remain effective.
Jun 29, 2023	D · Potential for harm, one-off	The facility did not keep all essential equipment working safely — things like heating and cooling systems, kitchen equipment, and medical devices.

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)	3.33	4.31	3.95	bottom 5% in California; bottom 28% in the U.S.
Registered Nurse hours	0.29	0.61	0.69	bottom 11% in California; bottom 9% in the U.S.
Weekend total nurse staffing	3.04	3.90	3.50	bottom 5% in California; bottom 33% in the U.S.
Weekend RN hours (not acuity-adjusted)	0.23	0.51	0.48	bottom 17% in California; bottom 18% in the U.S.
Total nursing staff turnover (%)	51.5	36.7	45.8	bottom 12% in California; bottom 33% in the U.S.
RN turnover (%)	0.0	38.1	42.9	—

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 3.72, RN 0.32, weekend 3.40. Staffing rating: 2/5.

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: 4/5 · long-stay residents: 5/5 · short-stay residents: 4/5
