Corona sits in western Riverside County, a growing city of more than 170,000 people served by a county-level treatment infrastructure that has evolved significantly over the past decade. All residential alcohol and drug recovery or treatment facilities operating in Corona must hold a valid license from the California Department of Health Care Services (DHCS) through its Substance Use Disorder Compliance (SUDC) Division Licensing and Certification Branch.
Outpatient detox and SUD treatment programs are required to hold a separate DHCS certification. This requirement became mandatory under California Health and Safety Code Chapter 7.1, which took full effect in January 2025.
The county’s public treatment system is operated through Riverside University Health System Behavioral Health (RUHS-BH), which runs a Substance Abuse Prevention and Treatment (SAPT) program with a dedicated clinic in Corona. Residents can call the county CARES Line at (800) 499-3008 any time, day or night, for a clinical assessment and referral.
When evaluating options, keep in mind that Corona’s treatment community includes private facilities and publicly funded county clinics. If you are searching for the right fit, understanding how to choose a detox center can help clarify the differences between hospital-based medical detox, residential programs, and outpatient care.
In May 2025, RUHS-BH also received more than $333 million in state Behavioral Health Continuum Infrastructure Program (BHCIP) funding from Proposition 1 to expand services across Riverside County, which will increase local treatment capacity over the next several years.
