Largest nursing home companies in California
There are 1,134 Medicare-certified nursing homes in California. The ten largest operators control 474 of them — 42% of the state.
This ranking counts what each company actually controls. CMS files list operators as separate legal entities, so a group running 133 buildings can appear as 11 unrelated companies. The rankings you find elsewhere count the paperwork; this one counts the buildings.

California nursing home chains and corporations, explained
People search for California nursing home companies in a dozen ways — largest nursing homes, top nursing home chains, nursing home corporations, biggest nursing home groups. They are all asking the same thing: who is actually behind the sign on the building. The answer is in CMS ownership filings, which are public, free, and almost unreadable in raw form.
How this is calculated
Every Medicare-certified nursing home files its owners with CMS. We take those filings, group entities whose facility portfolios overlap into a single corporate family, and count distinct facilities. Entities appearing only as lenders or mortgage holders are excluded — a bank holding paper on a building does not operate it. Full method on the methodology page.
