Where can I find living arrangements for low income Dad who's an alcoholic?

Dad moved in with me last month. He lived in the backwoods, 7 miles from nearest town, reliant on driving. With the terrible winter in the east and a broken down vehicle, he'd become housebound, and getting more feeble. I got him Meals on Wheels so he'd have at least one decent meal per day.

His monthly income is totally from SS, $900/mo. He did not own the place where he was staying, and he has no other assets to sell.

So we moved him (and his dog) 2500 miles to stay with me. BAD mistake. He's an alcoholic, drinks in his room, thinking I cant tell. Last night he was stumbling around naked, incoherent, and had an "accident" (poop in the hallway) before he could make it to the bathroom.

He has a long-standing problem with alcohol, which I began noticing when he was about age 50. He didn't drink when I was a kid, but made up for it when he got older. He got a DUI a few years ago.

My poor mother went through hell with him and died a couple years ago, I think to get away from him. Since I haven't lived with him for a long time, I didn't realize how bad his alcohol problem is.

He's been examined twice by doctors in the last 6 months. They have pronounced him "mentally competent," and fine on his own. If he's not drinking, he's alert and even charming.

Dad is totally stubborn and wants to do things his way. He won't apply for Medicaid, and won't go to AA or other treatment. I'm not going to let him ruin my my own life, as it's intolerable to have a volatile drunk in my house.

I work full time,and am not in a position to be a caretaker. I'm also not going to pay thousands per month for a live-in caretaker or assisted living (not that we have the money, or that he'd go anyway, or even that he'd qualify, since 2 different medical professionals have determined that he's "competent").

Does anyone have any suggestions on what resources might be available to provide to him before he's out on the street?
