Assisted living residences or assisted living facilities (ALFs) are housing facilities for people with disabilities. These facilities provide supervision or assistance with activities of daily living (ADLs); coordination of services by outside health care providers; and monitoring of resident activities to help to ensure their health, safety, and well-being.

Assistance may include the administration or supervision of medication, or personal care services provided by a trained staff person.

Assisted living as it exists today emerged in the 1990s as an eldercare alternative on the continuum of care for people, for whom independent living is not appropriate but who do not need the 24-hour medical care provided by a nursing home and are too young to live in a retirement home. Assisted living is a philosophy of care and services promoting independence and dignity.
