Frequently Asked Questions

How do I find and vet a home care agency in San Mateo?
To find the best home care in San Mateo, start by filtering our directory by the specific level of care needed, such as companion care or specialized dementia support. Once you have a shortlist, verify that the agency is licensed by the California Department of Social Services. We recommend asking three critical questions during your initial call: "How do you screen your caregivers?" "What is your backup plan if a caregiver is sick?" "Are your caregivers W-2 employees or 1099 contractors?" (W-2 employees are generally better for consumer protection).
Are the providers in the HomeCareAtlas directory licensed?
The HomeCareAtlas directory includes providers sourced from public records, including CMS Home Health Compare data and state licensing databases. We display available licensing and quality data where we have it. In California, most home care organizations must hold a Home Care Organization (HCO) license. We encourage families to independently verify that any agency they are considering holds active licensure and insurance in California. You can check an agency's license status directly with the California Department of Social Services.
What is the difference between Home Care and Home Health in California?
This is a common point of confusion for families in San Mateo. Home Care: Provides "non-medical" support, such as help with bathing, dressing, meal preparation, and transportation. This is typically paid for out-of-pocket or via Long-Term Care Insurance. Home Health: Provides "skilled medical care," such as wound care, physical therapy, or medication administration. This is usually prescribed by a doctor and may be covered by Medicare or private health insurance.
How much does home care cost in San Mateo?
Home care in San Mateo runs about $37 to $49 per hour, averaging about $43/hr, depending on hours booked and the level of specialized care. Rates track nearby markets: Redwood City has 17 agencies listed and charges comparable rates, so cross-shopping nearby cities is a useful way to sanity-check quotes. Most agencies in San Mateo County require a 4-hour minimum shift. If you need around-the-clock care, ask about flat daily "live-in" rates, which can be cheaper than hourly for 24/7 supervision.
Does Medicare or Insurance cover home care in San Mateo?
Standard Medicare generally does not cover non-medical home care (custodial care) in California. However, if your loved one has a Long-Term Care Insurance policy, it will likely cover these services after a waiting period. For veterans in San Mateo, you may be eligible for the VA Aid and Attendance benefit, which can provide a significant monthly stipend specifically for home care. Some Medicare Advantage plans in California have also begun offering limited in-home support services as a supplemental benefit.
Is home care a safe alternative to Assisted Living in San Mateo?
Home care allows seniors in San Mateo to "age in place" in a familiar environment, which is often preferred for those with early-to-mid-stage dementia. It is a safe alternative to a facility as long as the home is modified for safety (e.g., grab bars, no rug hazards) and the level of care matches the senior's needs. If a senior requires constant medical intervention or is a high flight risk due to advanced Alzheimer's, a specialized memory care facility in San Mateo County might be a more appropriate long-term solution.
What does the CMS Quality Rating mean?
Agencies with a Medicare Quality Rating have been evaluated by the Centers for Medicare & Medicaid Services (CMS) based on clinical outcomes. The rating looks at how well patients improve in areas like mobility, pain management, bathing independence, and medication management. It also measures how quickly care starts and how often patients avoid unnecessary hospital visits. Ratings range from 1 to 5 stars. Not all agencies in San Mateo have CMS ratings — non-medical home care agencies and newer agencies may not be rated. A CMS rating reflects the skilled home health side of an agency's services, not non-medical companion care.
How many home care agencies are in San Mateo?
San Mateo has 109 home care agencies listed in our directory, serving San Mateo County. This includes Medicare-certified home health agencies and non-medical home care providers. For context, nearby Redwood City (17) and South San Francisco (10) show up in our directory with their own agency counts — useful if you want to widen your search. About 17.0% of San Mateo residents are age 65 or older, which drives steady local demand for in-home care.
What questions should I ask when interviewing a home care agency?
When interviewing agencies in San Mateo, ask these key questions: Are your caregivers W-2 employees or independent contractors? (W-2 means the agency handles payroll, insurance, and liability.) What background check process do you use? What happens if my regular caregiver is unavailable? Can I meet the caregiver before services begin? What is your minimum shift requirement? How do you handle complaints or emergencies? Do you create a written care plan? For a more detailed guide, see our full article on how to choose a home care agency.
What is the difference between a home care agency and a home care registry?
An agency employs caregivers directly as W-2 employees. The agency handles payroll, taxes, insurance, training, supervision, and backup coverage if a caregiver is unavailable. A registry connects families with independent caregivers who are 1099 contractors — the family becomes the employer of record and takes on liability for payroll taxes, workers comp, and oversight. Agencies typically cost more per hour but include insurance, backup coverage, and professional oversight. In California, agencies and registries are regulated differently — agencies must hold a Home Care Organization (HCO) license from the California Department of Social Services.
