Licensing for Asst Living and Continuous Care (aka Nursing or Skilled) is mostly left up to the states, as is enforcement of such. Therefore, what is "standard" in my state may not be so in yours. It is up to you to find out what your state laws and regulations are, unfortunately.
If you have questions regarding caregiving, assistance programs, facility care, etc., a good place to start is your local Area Agency on Aging. There is an AA in every state, one of the few federal programs nationwide. They will have branch offices in many counties, although of course they cannot be everywhere. They should always be your first stop - there will be many! - for seniorcare resources.
Back to facilities:
If a facility receives any federal funds, it must adhere to the guidelines set by the federal government. Many facilities don't take these funds, and are thus free to offer, or not offer, whatever it can.
A direct quote from an eldercare website (Argentum):
"...In your state or in the state where you’re seeking a senior living residence, you may find that some properties may be licensed, others may be unlicensed, some may accept Medicaid payments for services, and others may be limited to private pay. While this variety can be confusing, it has allowed senior housing to evolve and change to meet the variety of different markets and consumer preferences within those markets. "
Translated this means that states can, or choose not to, regulate what services are provided at Asst Lvg and Continuous Care facilities. Some states prohibit AL facilities from providing CC at all; other states do not.
So it's not a good idea to ask for general advice on the web unless you are very sure the answer APPLIES TO YOUR STATE OF DOMICILE. I could give you a very good rundown on senior/eldercare facilities in my area, but unless you live in the State of California that advice might be entirely useless to you.
In our state, Independent, Assisted, Skilled Care, and Continuous Care are all separate categories: very rigorously licensed and each with its own set of safety, inspection, and services requirements. Some facilities serve only one or two categories. Others may offer Continuous Care which is all three categories.
But the definition of CC will change from state to state; so again, know YOUR state's laws, or the laws of the state you intend to retire to.
HTH!
