Memory care is not priced here: a dementia-care designation is not on file for this home. Ask the home.
Starting monthly rate$6,200likely $5,050–$7,600
Covelight’s estimate starts from the rates 15 small homes and similar homes within 3 miles publish, then adjusts for this home’s size, state care approvals, Medi-Cal waiver participation, years licensed and the area’s prices. In testing, the likely range held the real rate for 6 in 10 homes. This home’s own rate is not on file.
Basic help with daily careUsually includedup to $600

How people payPrivate pay, Medi-Cal waiver, SSI/SSP, veterans, insurance
- MedicareDoes not pay for room and board in a care home. It can still cover hospice or home-health visits inside one.
- Private payMost residents pay from savings, a home sale or family help. Ask for the rate and what it includes in writing.
- Medi-Cal Assisted Living WaiverThis home is not on the DHCS participation list dated October 1, 2026. Ask the program about current options. The waiver pays for care services, not room and board.
- SSI/SSPCalifornia’s 2026 standard is $1,626.07 a month; $1,444.07 of it goes to the home and $182 stays with the resident. Whether this home accepts it is not on file — ask.
- VeteransVA Aid & Attendance can add to a veteran’s or surviving spouse’s pension. Ask whether residents here have used it.
- Long-term care insuranceMost policies pay for licensed care homes. Ask what paperwork the home provides for claims.

How this estimate worksWithin 25% for 7 in 10 homes in testing
Covelight’s estimate starts from the rates 15 small homes and similar homes within 3 miles publish, then adjusts for this home’s size, state care approvals, Medi-Cal waiver participation, years licensed and the area’s prices. In testing, the likely range held the real rate for 6 in 10 homes. This home’s own rate is not on file.
- Only prices a home put out itself count: its own website, a listing it supplied, or a price Seniorly says the home confirmed. Prices a listing site shows without saying where they came from are left out.
- Nearby homes are the nearest of the same size that publish a rate, widening from 3 to 40 miles until at least 8 do. The estimate starts from what they charge, then adjusts for this home’s size, state care approvals, Medi-Cal waiver participation, years licensed and the area’s prices.
- Room, care-level, second-person and move-in lines come from what California homes publish on listing sites. Memory care uses Covelight’s researched premium over assisted living.
- Totals add each line’s figure and combine the lines’ ranges as separate charges, because a home is rarely at the top, or the bottom, of every line at once.
- We tested this estimate on 1,546 California homes that publish their own starting rate. It was within 10% of the real rate for 3 in 10 homes and within 25% for 7 in 10; the likely range held the real rate for 6 in 10 (September 12, 2026).
- It cannot see this home’s specials, how it assesses care, or which rooms are open.
Avoid surprises on the billWhat changes the price, and what to ask
- The care level
Some homes charge one all-inclusive rate. Others add levels or points as needs grow. Ask how the level is set, who decides, and what the next level costs.
- What is billed separately
Medication management, incontinence supplies, transportation and a second person in the room are often extra. Ask for the list in writing.
- Move-in costs
A one-time move-in fee or deposit is common. Ask what it covers and whether any of it comes back if the stay is short.
- Increases
California requires at least 90 days’ written notice, with reasons, before a rate rises (Health & Safety Code §1569.655). A change in the resident’s care level is the section’s own exception and can be billed sooner.
An estimate for planning, not a quote. A home sets the price after hearing about the care needed.

“Typical” is the statewide median for licensed homes this size. It does not adjust for years licensed, and older licenses have had more visits and reports. The median is across the 6,916 licensed small board-and-care homes (6 or fewer beds) in the state record. The figures compared are the state’s totals, not the documents.

An “unsubstantiated” complaint is not a finding of wrongdoing — it means the state investigated and could not confirm the allegation. Outcome words are the state’s own; we never grade, score, or color a record, and we publish no reviews — the state’s dated documents stand in their place.

A citation does not make a home unsafe, and an empty file does not make a home good.

What does Chateau Sabelle cost?
$6,200 a month to start is a Covelight estimate, likely $5,050–$7,600. This home’s own rate is not on file. Ask: “What is the all-in monthly rate, and what would push it higher?”
Covelight’s estimate starts from the rates 15 small homes and similar homes within 3 miles publish, then adjusts for this home’s size, state care approvals, Medi-Cal waiver participation, years licensed and the area’s prices. In testing, the likely range held the real rate for 6 in 10 homes. This home’s own rate is not on file.
Among 18 other homes of a similar licensed size in San Mateo that publish a starting rate, the middle half runs $6,000 to $7,000 a month, and the middle figure is $6,600 (n = 18 other homes publishing a starting rate).
Each of those is a home’s own published figure, gathered on its own date between September and October 2026 — not an average of ours, and not a survey. Similar size means small and mid-size homes counted together, and large communities counted on their own, because they are different markets.
A home outside the band is not overcharging or underpricing: a starting rate covers different things in different homes, which is the first thing to ask about.
The price is made in the phone call. Nothing here is a quote, an offer or a discount.
A starting rate is the room and the base care. California homes commonly bill care levels, medication management, supplies, transport and a second person in the room as extras. Many also charge a one-time fee at move-in. Ask for that list in writing before anything is signed.
Only prices a home put out itself count here: its own website, a listing it supplied, or a price a listing site says the home confirmed. Prices a site shows without saying where they came from are left out.
