Community Care Licensing decides complaints on a preponderance of the evidence standard: the evidence must show it is more likely than not (more than 50%) that the allegation is true.cdss.ca.gov

A complaint allegation is substantiated when the preponderance of the evidence standard is met.cdss.ca.gov

An allegation is unsubstantiated when the investigation shows there is not enough evidence to prove a violation occurred.cdss.ca.gov

An allegation is unfounded when the evidence shows it could not have happened, is false, or has no reasonable basis.cdss.ca.gov

Memory care

California does not issue a separate memory care licence, and the state's roster does not mark which homes care for residents with dementia. Ask the home how it cares for residents with dementia, and check the citations above.

California's updated dementia care rules for RCFEs took effect January 1, 2025. They aim to support person-centered care and let residents age in place in the least restrictive setting they know as home.cdss.ca.gov

The dementia care standards, once kept in one regulation section, are now spread across several sections so they support care for all residents.cdss.ca.gov

The rules now address resident behaviors whatever the diagnosis, focusing on individual needs, and whether a resident may have items such as cleaning solutions or sharp objects depends on their own needs and appraisal.cdss.ca.gov

Costs

California does not publish what assisted living homes charge, and Sage Mountain Senior Living has no rate on file with us. Ask the home for its full rate sheet, including care level fees and any one-time community fee, before you sign.

An RCFE must give residents or their representatives at least 90 days' written notice of a rate increase, with the amount and the reasons, including a description of the added costs. Increases due to a change in the resident's level of care are an exception.ahum.assembly.ca.gov

When the rate goes up because a resident's level of care changes, the RCFE must give written notice within two business days after it starts providing the new level of care.ahum.assembly.ca.gov

If you have a concern

NursingHomeClear cannot take or act on complaints. California's Community Care Licensing Division investigates complaints about licensed homes, and the long-term care ombudsman is a free, confidential advocate for residents.

California's long-term care ombudsman programs advocate for residents of skilled nursing facilities and of 8,105 residential care facilities for the elderly.aging.ca.gov

California long-term care facilities must post the local ombudsman's number and the statewide hotline, 1-800-231-4024, which takes calls 24 hours a day, 7 days a week. Ombudsman services are free and complaints are confidential.aging.ca.gov
