Cronin House provides addiction recovery services in Hayward, CA through co-ed adult residential care. Our DHCS-licensed program uses measurement-based care.
There is no judgment here.
At Cronin House, you get structured, 24/7 residential care for substance use and co-occurring mental health conditions. Stays can last up to 90 days, based on your clinical needs, in a co-ed adult program.
Our team includes compassionate professionals, many of whom are in recovery themselves. They understand what you’re facing and offer real-world guidance and 24/7 support as you build a stable path forward.
You’ll live in a safe, supportive setting where you can practice new routines and lifestyle choices. Once a month, Cronin House hosts an Awards Night that celebrates recovery milestones for current clients and alumni. Families are invited to join, and there’s dessert to mark the occasion.
