Many people who complete addiction treatment still need support after treatment ends. This stage can be difficult because daily life often brings new pressure, old routines, and possible exposure to alcohol or drug use.
A sober living house helps bridge that gap. It gives people a stable, alcohol- and drug-free place to live while they continue building a sober life.
A major study by Douglas L. Polcin, Ed.D., Rachael Korcha, M.A., Jason Bond, Ph.D., and Gantt Galloway, Pharm.D. helps show why this kind of housing matters. Their paper, What Did We Learn from Our Study on Sober Living Houses and Where Do We Go from Here?, reviewed findings from a study of 300 people living in two types of sober living houses over an 18-month period.
The Study Behind the 620% Sober Living Success Claim
The strongest number in the study came from Options Recovery Services (ORS) in Berkeley, California. This program combined outpatient treatment with sober living housing.
At the start of the study, 11% of ORS residents had six-month abstinence. At six months, that number increased to 68%. At 12 months, it remained 68%. At 18 months, the rate was 46%, still much higher than baseline.
That 68% abstinence rate is more than six times the 11% baseline rate. This is where the claim that sober living can improve success by about 620% comes from.
This does not mean every sober living house will produce the same result. It means that, in this study setting, residents had a much higher abstinence rate after entering a structured sober living environment.
The 620% figure comes from one program in one study: six-month abstinence at Options Recovery Services rose from 11% at entry to 68%. It shows what a structured sober living setting achieved there, not a result every home can promise.
The authors explain why the living environment matters:
“Lack of a stable, alcohol and drug-free living environment can be a serious obstacle to sustained abstinence. Destructive living environments can derail recovery for even highly motivated individuals.”
These quotes are important because they connect the study’s results to a clear recovery problem: many people leave treatment without a stable place to continue recovery.
How the Sober Living Study Was Designed
The study followed residents in two sober living house models.
The first model was Options Recovery Services (ORS) in Berkeley, California. ORS connected sober living housing with outpatient treatment.
The second model was Clean and Sober Transitional Living (CSTL) in Sacramento County, California. CSTL operated freestanding sober living houses that were not connected to formal treatment.
Residents were interviewed at four points:
- During their first week in the sober living house
- At six months
- At 12 months
- At 18 months
The researchers measured alcohol and drug use, employment, arrests, mental health symptoms, social support, and 12-step involvement.
This structure matters because it followed residents over time. Instead of only asking whether sober living helped in theory, the study tracked what happened after people entered the houses.
Sober Living Abstinence Rates at 6, 12, and 18 Months
Both sober living models showed improvement in abstinence, but the results were different by setting. Here are the abstinence rates for each program at every interview point.
| Time point | Options Recovery Services (Berkeley) | Clean and Sober Transitional Living (Sacramento County) |
|---|---|---|
| Baseline | 11% | 20% |
| 6 months | 68% | 40% |
| 12 months | 68% | 45% |
| 18 months | 46% | 42% |
The study also measured the highest number of substance-use days in a month. At ORS, the average dropped from 19 days at baseline to 3 days at six months, 4 days at 12 months, and 7 days at 18 months. At CSTL, it dropped from 19 days at baseline to 11 days at six months, 9 days at 12 months, and 13 days at 18 months.
These numbers show that sober living was linked with both higher abstinence and fewer days of substance use.
Sober Living Also Supported Daily Stability
The study did not only look at sobriety. It also looked at whether residents improved in everyday life.
At CSTL, residents improved in several areas:
- Employment
- Mental health symptoms
- Arrests
Arrests dropped from 42% in the six months before baseline to 26% at six months and 22% at 12 months. At 18 months, arrests increased slightly to 28%, but this was still lower than baseline.
At ORS, employment also improved. The odds of being arrested dropped by 80% from baseline to six months, and the reduction continued at 12 and 18 months.
These findings matter because recovery is not only about avoiding alcohol or drugs. It is also about rebuilding stability, work, relationships, and daily life.
Why the Living Environment Matters
The study supports a simple point: where a person lives after treatment can affect recovery.
A person may leave treatment with strong motivation. But if they return to an unsafe or unstable environment, recovery can become harder. They may face old triggers, conflict, isolation, or easy access to substances.
A sober living house helps reduce those risks by creating a recovery-focused setting. That setting often includes:
- A substance-free home
- Clear house rules
- Peer support
- Regular routines
- Recovery-focused expectations
The authors described sober living houses as alcohol- and drug-free living environments for people trying to abstain from alcohol and drugs. These houses usually do not provide formal treatment. Instead, they focus on peer support, house rules, resident responsibility, and daily recovery routines.
12-Step Involvement and Social Support Predicted Better Outcomes
The study found that two factors were especially important.
First, 12-step involvement was one of the strongest predictors of better outcomes. Residents who were more involved in 12-step groups were more likely to have better recovery results.
This involvement was linked with:
- Higher abstinence
- Fewer substance-use days
- Fewer arrests
- Lower legal problems
Second, social support mattered. At CSTL, heavier alcohol and drug use in a resident’s social network was linked with worse outcomes. This shows why sober peer support can be so important after treatment.
A sober living house can help residents build healthier connections by placing them in a setting where other people are also focused on recovery.

How Long Residents Stayed in Sober Living
The study also found that residents often stayed long enough to benefit from the sober living environment.
Average length of stay was:
- 254 days at ORS
- 166 days at CSTL
Both averages were longer than 90 days. The authors compared this with the National Institute on Drug Abuse recommendation of at least 90 days to receive maximum benefit from treatment.
This matters because recovery takes time. Residents may need time to build sober routines, find work, repair relationships, strengthen support systems, and prepare for independent living.
The study also found that many residents kept improving even after they left sober living. By 18 months, nearly all residents had left the houses, but many improvements were still maintained.
What the Study Does Not Prove
The study is important, but it needs to be explained carefully.
It does not prove that every sober living house will produce a 620% improvement. It also does not prove that sober living alone caused every positive result.
The study had two key limitations:
- Residents chose to enter sober living, so personal motivation may have affected the results.
- The two sober living models served different groups of people, so they cannot be directly compared.
Even with those limits, the findings are useful. They show that residents in these sober living houses improved in several major areas over time.
- ✓Policies and house agreements to have signed
- ✓Inspections, insurance, and intake paperwork
- ✓What the first week actually requires
What This Means for Families and Referral Partners
This study shows that sober living can be an important next step after treatment, especially when a person does not have a stable sober place to live.
A sober living house may help someone who:
- Has completed treatment but still needs structure
- Needs distance from old triggers
- Benefits from sober peer support
- Needs more time before living independently
- Is rebuilding work, routines, and daily stability
For families, this means housing choice matters. A supportive home environment can help protect early recovery.
For treatment providers and referral partners, the study supports sober living as a practical recovery support option after treatment.
For families Choosing the Right Sober Living HomeWhy More Quality Sober Living Homes Are Needed
Many communities do not have enough quality sober living homes. This creates a gap between treatment and long-term recovery.
A well-run sober living home provides more than a bed. It offers a stable, substance-free setting with clear expectations, peer support, accountability, and time to rebuild daily life.
The Polcin, Korcha, Bond, and Galloway study shows that sober living houses can support measurable improvement in:
- Abstinence
- Substance use
- Arrests
- Employment
- Mental health symptoms
That is why sober living homes matter. They help people continue recovery in daily life, not just during treatment.
Frequently Asked Questions About Sober Living After Treatment
How long should someone stay in a sober living home?
The length of stay can vary depending on individual needs, but longer stays are often linked with better outcomes. Many residents benefit from several months of structured support. This time allows them to build routines, secure employment, and strengthen recovery habits.
Can someone work while living in a sober living home?
Yes, most sober living homes encourage residents to work or actively seek employment. Having a job helps build responsibility and financial stability. It also supports a structured daily routine that reinforces recovery.
Are sober living homes only for people right out of treatment?
No, sober living homes can support people at different stages of recovery. Some residents enter immediately after treatment, while others join later to regain stability. The environment is designed to support ongoing recovery at multiple points.
What happens if someone breaks the rules in a sober house?
Each home has clear rules and consequences to maintain a safe environment. If rules are broken, there may be warnings, increased accountability, or removal from the home. This structure helps protect all residents and reinforces responsibility.
How do sober living homes help prevent relapse?
Sober living homes reduce exposure to triggers by offering a stable and substance-free setting. They provide accountability, peer support, and daily structure. These factors help residents stay focused and better manage challenges in early recovery.
How to Open a Sober House That Serves Your Community
Opening a sober house can be a meaningful way to support recovery in your community. It can also help meet the need for safe, structured housing after treatment.
A strong sober living home needs:
- Clear house rules
- Consistent leadership
- A substance-free environment
- Peer support
- Connection to outside recovery resources
- A recovery-focused culture
Clinical experience is not always required to become an operator, but a strong framework is important.
Vanderburgh Sober Living (VSL) is a cooperative network of independently operated sober houses. VSL supports mission-driven operators with guidance, systems, certification support, and an ongoing community.
