How this estimate worksWithin 25% for 7 in 10 homes in testing
Covelight’s estimate starts from the rates 13 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).

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.

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.

What does A Diablo Assisted Living 1 cost?
$5,200 a month to start is a Covelight estimate, likely $4,250–$6,400. 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 13 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 7 other homes of a similar licensed size in Walnut Creek that publish a starting rate, the middle half runs $3,875 to $6,500 a month, and the middle figure is $5,000 (n = 7 other homes publishing a starting rate).
Each of those is a home’s own published figure, gathered on its own date in September 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.
Does A Diablo Assisted Living 1 take Medi-Cal?
On Medi-Cal’s Assisted Living Waiver: this 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.
