Generally, all rikishi (sumo wrestlers) belong to a stable or sumo beya. Young sumo wrestlers enter the heya and will stay there for the entirety of their careers. They have responsibilities like cooking, cleaning, and caring for the senior rikishi of the heya. Junior rikishi live in dormitory-style accomodations. I believe high ranking and married rikishi can live seperate from the sumo beya.
Each sumo-beya is headed by an Oyakata who generally is a former high-ranked rikishi who now trains and cares for lower-ranked rikishi. Currently there are a couple of stables headed by non-japanese: Narutobeya headed by Bulgarian former rikishi Kotoushuu and Musashigawa-beya headed by former American Yokozuna: Musashimaru.
As wrestlingnerd indicates above high ranking rikishi (Juryo level and above) receive good salaries; lower-ranked sumo wrestlers do not earn all that much, however their daily expenses are paid. As they work their way up (and possibly attain seniority) they get better stipend and better jobs in the heya.
