Alcohol and other drug-free residences (which may be single family dwellings, duplexes, multiplex apartment buildings or communal residential facilities) for people who are recovering from an alcohol and/or other drug use disorder and need a sober environment in order to sustain an abstinent lifestyle. Residents are free to organize and participate in support group meetings or any other activity that helps them maintain sobriety, but neither the homes nor the residents provide treatment, recovery, detoxification services or other supportive services; and supervision of individual recovery is not provided. Because they provide no services, sober living homes do not require a license but are generally subject to landlord/tenant laws.
