What does A Beloved Home of Diamond Bar cost?

$4,500 a month to start is a Covelight estimate, likely $3,700–$5,550. 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 24 small homes and similar homes within 8 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 228 other homes of a similar licensed size across Los Angeles County that publish a starting rate, the middle half runs $4,000 to $6,300 a month, and the middle figure is $5,000 (n = 228 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. What Medi-Cal’s Assisted Living Waiver covers in a care home.

Does A Beloved Home of Diamond Bar take Medi-Cal?

On Medi-Cal’s Assisted Living Waiver: this home appears on the DHCS participation list, August 9, 2026. Confirm eligibility and current participation with the program. The waiver pays for care services, not room and board.

Who holds the license?

The license is held by A Beloved Home of Diamond Bar LLC, per CDSS records as of September 13, 2026.

Can A Beloved Home of Diamond Bar keep a resident on hospice?

Hospice care is approved on this license, covering up to 6 residents, per CDSS records as of September 13, 2026.

How people payOn the Medi-Cal waiver list · private pay, SSI/SSP, veterans, insurance
  • 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 appears on the DHCS participation list, August 9, 2026. Confirm eligibility and current participation with the program. The waiver pays for care services, not room and board. For a resident on SSI/SSP, California’s 2026 standard sends $1,444.07 a month to the home for 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.
  • MedicareDoes not pay for room and board in a care home. It can still cover hospice or home-health visits inside one.
If the money runs out, what Medi-Cal covers
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 community 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.

  • What is the full monthly cost for the room and care we need, and what does it include?
  • What would the next care level cost, and who decides when it changes?
  • What is billed separately, and is there a one-time fee or deposit at move-in?
  • Is any private-pay period required before another payment program can begin?
How this estimate worksWithin 25% for 7 in 10 homes in testing

Covelight’s estimate starts from the rates 24 small homes and similar homes within 8 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.

24 homes like this within 8 miles publish starting rates mostly between $3,300–$5,000.

  • 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).

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 and the questions below stand in their place.

Life here

Rooms, meals, the rhythm of a day, faith and language, pets and house rules — as the home describes them. Tap any detail for its source and date; nothing here is graded.

The home has not described daily life anywhere we have reviewed yet — that is the case for most small homes, and it says nothing about the home. These questions fill in the picture; keep the ones that matter to you.

Before you call

Ask every home the same questions — the state’s record does not answer these. Keep the ones that matter and they travel with your saved homes.

  1. What is included in the monthly rate, and what costs extra?
  2. Who is awake overnight, and how do residents ask for help?
  3. Which rooms does the non-ambulatory approval cover, and what transfer support is provided?
  4. What could change whether someone can stay here?
  5. Can we see a bedroom and share a meal during a visit?
