What is an Adult Foster Care Home in Oregon? When elderly people or adults with physical disabilities are no longer able to care for themselves in their own homes, adult foster care may be an option. Adult foster homes are single-family residences that offer 24-hour care in a home-like setting. A wide variety of residents are served in Adult Foster Homes, from those needing only room, board and minimal personal assistance to those residents needing full personal care, or skilled nursing care with the help of community-based registered nurses.
