I'm not sure what you mean when you ask whether "this facility" is obligated to do something. When she (you) moved to your home, I'm guessing that the facility was no longer responsible for her well-being.
Not sure what you mean by "bias discriminatory assumption". Please consult with an attorney in your area to make sure everything you are concerned about is addressed.

You should first deal with the eviction. If it is for non-payment of rent, then there may not be anything you can do, however, if you can avoid having the eviction on your credit report, you should do so (one way to do that is to have a "move out deal" with the LL where you agree to move by a certain date if she/he dismisses the eviction proceeding or doesn't go to court). You should consult with a housing attorney or your local legal aid organization (your mother may qualify for their services as a senior with disabilities). If you have complaints about the treatment she was given at the care facility, you should file a complaint with the state department of health. You may also want to speak with a non-profit organization that deals with nursing/care facilities, such as CANHR.
