Well I live in the UK and over here it depends on the disability whether you live alone or not, but many people do so I can't see it being any different where you are.
Many people who are disabled can live a normal life in a place of their own, in which you can also have a carer come visit if need be. My step father's uncle has lost his legs and has false ones and he lives on his own. He has his food delivered by a company that specialises in food for the elderly and disabled, and I think he has a nurse come visit to assist him with things. The only time I've known him not be able to live on his own was a few months ago when he broke his hip. The hospital made him stay there whilst be recovered and then transferred him to a nursing home.
That aside, he is back home and indipendant again.
