Well if you don't plan to enable her, I would put off the 'housing her' thing, and of course stop buying any beer, or doing anything that creates a safe landing for her.
If she wants to get sober, and needs to detox she can call 911. She can call the Salvation Army, it's free.. it's rehab. She can call AA. As long as she doesn't have consequences for what she's doing, she has absolutely no reason to change. Allow her the dignity to suffer the real consequences of what she is doing to her self, and to pursue a better life, and recovery on her own, if she ever wants it. If she is in need of emergent medical or mental health care, call 911.
