Rehab in Los Angeles typically lasts between 30 and 90 days, depending on the individual's needs, the severity of their addiction, and the type of treatment program they enroll in. In some cases, long-term residential care may extend to six months or longer to support full behavioral stabilization and relapse prevention.

What Determines the Duration of Rehab in LA?
Several clinical and logistical factors influence the length of stay:
- Type of Substance Use Disorder (SUD): Individuals with long-term or multiple addictions may require extended treatment timelines.
- Co-occurring Conditions: Patients with dual diagnoses (e.g., addiction and depression) often need longer stays for integrated mental health treatment.
- Treatment Type: Outpatient programs are typically shorter, while inpatient or residential programs can last significantly longer.
- Progress and Compliance: Programs may adapt length based on patient milestones such as detox completion, participation in therapy, and sobriety duration.

Common Rehab Program Lengths in Los Angeles
Rehab centers in Los Angeles generally offer standardized program lengths with flexibility built in:
- Detox Programs (5–7 Days): Medically supervised detoxification to manage withdrawal symptoms.
- 30-Day Programs: Designed for individuals with lower levels of dependence or strong external support systems.
- 60-Day Programs: Allow more time for therapy, habit-building, and emotional stabilization.
- 90-Day Programs: Recommended for individuals with chronic addiction histories or co-occurring disorders.
- Extended Programs (120+ Days): Tailored for long-term recovery needs, sometimes including transitional living arrangements.
Why 30 Days Is Not Always Enough
While many insurance policies default to covering 30-day treatment, research indicates that longer durations are associated with higher success rates. According to the National Institute on Drug Abuse (NIDA), programs lasting at least 90 days show the best long-term outcomes in relapse prevention and patient well-being.

Benefits of Longer Rehab Durations
Choosing a longer program can offer several clinical benefits:
- Stronger coping mechanisms through repeated therapeutic exposure.
- More time to address trauma or root causes.
- Better preparation for reintegration, including relapse prevention planning.
- Gradual independence with monitored steps toward outpatient care or sober living.
When Short-Term Rehab Is Effective
Not all individuals need extended care. Short-term rehab may be effective if the person:
- Is attending treatment early in their addiction trajectory.
- Has a strong support network outside of rehab.
- Maintains high motivation levels for recovery.
- Has no co-occurring mental health conditions.
How Long Do Outpatient Programs Last?
Outpatient rehab in Los Angeles can range from one month to over a year, depending on intensity:
- Standard Outpatient (1–3 Months): Includes 1–3 weekly sessions for therapy and check-ins.
- Intensive Outpatient Programs (IOP) (2–4 Months): Provide 3–5 sessions per week, allowing clients to maintain work or school schedules.
- Partial Hospitalization Programs (PHP) (1–3 Months): Offer daily care without overnight stays, lasting up to 6 hours per day.
Transitioning to Aftercare or Sober Living
Upon completing a formal program, many clients transition to:
- Sober Living Homes in Los Angeles, which offer structure and accountability.
- Aftercare programs that include regular therapy, alumni meetings, and medication-assisted treatment if applicable.
These additional supports help reduce relapse risk and improve long-term outcomes.
Is Longer Always Better?
Longer programs aren't universally better — the ideal duration is tailored to individual needs. Rehab should be long enough to address both physical and psychological recovery, but not so long that it delays reintegration without purpose.
For individuals seeking discretion, comfort, and privacy, many opt for a luxury rehab in Los Angeles where they can receive extended care in a supportive environment.
