Recovery residences have spread rapidly in the United States in recent decades. In 2011, the National Association of Recovery Residences (NARR) was founded to promote a recovery-oriented continuum of support for those with substance use disorders by credentialing recovery residences that implement empirically-based recovery principles and practice standards. NARR currently represents more than 1,900 recovery residences in the United States. The purpose of this document is to answer some of the most frequently asked questions about recovery residences.
