I have a family member that may be living there how could I find that out

You cant. They wont tell you anything about any residents especially if they are victim to DV.

The short answer is "no." If you are on good terms with this person, you should ask them. Otherwise, MYOB.

You can't. It's a closed facility. They don't tell you at the front desk or if you call there n ask for residents. And there are no phones in the rooms people stay in unless they have cell phones
