What these terms mean
Type A citations are for “the most serious type of violations in which there is an immediate risk to the health, safety or personal rights of those in care,” and are issued “even if the violation is corrected on the spot.”
Type B citations are for “a violation that, if not corrected, may [pose] an immediate risk to the health, safety or personal rights of clients,” such as faulty medical record keeping or staff training.
CCLD: “There is no difference between an inconclusive and an unsubstantiated complaint allegation. Both terms mean that there was no preponderance of evidence to prove that an alleged violation occurred.” Allegations CCLD finds unfounded are also not substantiated.
This community is licensed for 6 residents; larger communities are visited and complained about more often, so read counts with size in mind.

Paying with Medicaid and other programsHow Medicaid pays for care in California, and other programs
How Medicaid pays for care in California
- Assisted Living Waiver (ALW). Medi-Cal can pay for assisted living care services through the Assisted Living Waiver, but only in 15 counties, only for people who need nursing home level care, and there is a waitlist. The resident still pays room and board. (state page)
- Waitlist. The Assisted Living Waiver has a waitlist. DHCS reported 18,365 people on it in December 2025. (source)
Ask the community whether it accepts Medicaid.

How Lilisity works. The only scores or rankings Lilisity publishes are the Top Communities list and the Excellence Awards, both built from phone-verified resident and family interviews. Communities can pay Lilisity a flat monthly fee to manage their own listing: photos, prices, contact details, and receiving the inquiries families choose to send them. The fee is the same no matter how many families contact them or move in. Senior Living Alliance, which runs Lilisity, offers the same listing to its member communities as part of their membership; members pay SLA for its resident and family interview program. No community pays Lilisity per inquiry, per referral or per move-in. Payment never changes a testimonial, a rating, or the order of search results. The "Nearby Senior Living Alliance communities" box shows member communities only. How we verify testimonials · How we are paid
