Our certification articles focus on state-level certification of sober houses, recovery homes, and all other sober living environments. Certification is handled by an agency for each state. Some states don’t have certifying agencies yet. Most of these state sober house certification organizations are affiliated with NARR, the National Alliances for Recovery Residences. State certification is voluntary and agencies which certify sober living homes follow a similar set of standards and expectations for sober house operators.
