An assisted living center is a residential living and medical care facility for people who may need help with daily needs such as bathing, grooming, dressing, laundry, housekeeping, and food preparation—and who may need some medical care or assistance with medication management—but not the degree of medical care provided by a nursing home. Assisted living centers are designed for senior citizens who are no longer capable of living alone but who want to enjoy some independence and the social aspects of group dining, activities, and outings to local places and events.

In Oregon, assisted living facilities (ALFs) are regulated by the Oregon Department of Human Services, Seniors and People with Disabilities Division. These facilities provide housing, residential care, and support services to elderly individuals who require assistance with daily living activities but do not need the full-time health care services provided by nursing homes. Oregon's regulations for ALFs include requirements for staffing, resident care, medication management, dietary services, and social activities. Facilities must be licensed and are subject to inspections to ensure compliance with state standards. Additionally, Oregon has a Bill of Rights for residents of long-term care facilities, which includes the right to be treated with respect, the right to privacy, and the right to receive care that is free from abuse or neglect. Assisted living residents in Oregon can expect to live in a safe environment that promotes their independence while providing the necessary level of care and support.
