I’ve found the following to be helpful questions when interviewing communities or residential care homes…
Observe the lobby when you enter…. How many staff are evident, and are residents “parked” in their wheelchairs? Are they napping in the lobby?
Ask what the staff to resident ratio is during the day AND night. (It will be different at night).
If a residential care home, is the staff awake or asleep during the night?
Is there an RN on staff, and do they reside at the home, or just accessible?

When was the last State survey done? (Should be less than two years). And will they make that report available for you to read? How many deficiencies and how serious were they? Were there fines levied? Are they currently out of compliance, or have they ever been out of compliance with the State?
Does the dietary staff accommodate special needs? Is there an extra charge?
What is the average response time when an assistance button is pressed?
(Most facilities have a program to monitor this).
Will the facility convert you to Medicaid from private pay when necessary? How many years do you need to have lived there before they will do this?
Is there a “fall” requirement they follow? (Some asst care facilities will chart falls, and when there are 3, they will either suggest another heavier care facility or require an increase in level of care and price).. some larger assisted care communities will require you then hire private caregivers if you want to not move.
How long has the Administrator been there? How long has the supervising RN been in place?
Don’t be afraid to take a complete tour…. Including the laundry area. Peek in to the staff lounge, and visit with a few of the residents….

It’s definitely a process of discovery. I hope this helps.
