(844) 569-1713There are 1198 SAMHSA-listed addiction treatment facilities in California. Los Angeles leads with 68 facilities, followed by San Diego (43) and Long Beach (28). At the other end of the spectrum, 138 of the listed communities have only one or two facilities — which matters, because for outpatient care especially, the closest option is often the most sustainable one.
A useful way to read this page: treatment capacity here is comparatively spread out — the top five cities hold only about 16% of listed facilities. If you need a harder-to-find program type, start with those hubs. If you need weekly outpatient care you can actually get to, start with the city list further down — smaller-town facilities are often the difference between finishing a program and quietly dropping out of one.
All 13 levels of care and program types we track are available somewhere in California — including the harder-to-find categories like medical detox, sober living, and teen treatment. Availability varies significantly by city, though; the table and program links below show where each level of care is actually offered.
Program Availability in California
| Program type | Facilities | Share of listed facilities |
|---|---|---|
| Medical Detox | 476 | 40% |
| Inpatient & Residential Rehab | 530 | 44% |
| Partial Hospitalization (PHP) | 234 | 20% |
| Intensive Outpatient (IOP) | 428 | 36% |
| Outpatient Rehab | 752 | 63% |
| Medication-Assisted Treatment | 814 | 68% |
| Sober Living Homes | 70 | 6% |
| Veterans' Rehab | 552 | 46% |
| Women's Rehab | 1091 | 91% |
| Men's Rehab | 1095 | 91% |
| Teen & Adolescent Rehab | 219 | 18% |
| Senior Rehab | 542 | 45% |
| Dual Diagnosis Treatment | 911 | 76% |
Reading the table: a facility can offer several program types at once, so the percentages overlap and won't sum to 100. In California, Men's Rehab is the most widely reported category (1095 facilities), while Sober Living Homes is the sparsest (70 facilities) — if you need one of the sparser categories, expect a shorter list of options and check the program page early in your search.

How to Choose a Rehab in California
The first question isn't "which facility?" — it's "how much structure does this situation need?" Detox, residential care, day programs, and outpatient counseling solve different problems, and a mismatch in either direction undermines the whole effort. Our levels of care guide lays out what each involves so you can narrow the field before comparing individual programs.
Distance matters differently at different levels of care. Outpatient treatment lives or dies on attendance, so favor what's genuinely reachable from the city list below. Residential treatment removes the commute entirely — which puts every facility in California, including the Los Angeles cluster, realistically on the table.
Handle the money question early, not at admission. Confirm network status directly with both the facility and the insurer — our insurance guide walks through exactly what to ask — and know that free and low-cost options exist if coverage falls through. If the person you're searching for fits a specific population — veterans, teens, women, seniors, or anyone managing a co-occurring mental health condition — the who-we-help guides are worth ten minutes before you start calling programs.
Cities in California
If Your City Isn't Listed
Facility locations don't limit who they serve. Some smaller communities in the list above show no local facilities of their own — their pages point to the nearest listed options instead, because facilities routinely serve patients from surrounding towns and counties, and larger hubs like Los Angeles and San Diego draw from most of the region. If your town isn't in the list at all, check the cities nearest you first — and remember that for residential care, anywhere in California — or beyond it — is within reach, since you stay on-site.
Frequently Asked Questions
How many addiction treatment facilities are in California?
There are 1198 SAMHSA-listed addiction treatment facilities in California, with the largest concentrations in Los Angeles, San Diego, and Long Beach. Every one appears in SAMHSA's National Directory, meaning it holds a state license, certification, or approval — this directory doesn't include unverified or scraped listings.
Which cities in California have the most rehab facilities?
Los Angeles has the most with 68 facilities, followed by San Diego (43) and Long Beach (28). The five largest hubs together hold about 16% of the state's listed facilities — but 138 smaller communities have one or two local facilities each, which often matters more for outpatient care you'll attend weekly.
Does California have every level of addiction care?
Yes — all 13 program types this directory tracks are reported by at least one facility in California, including medical detox, residential treatment, PHP, IOP, medication-assisted treatment, and sober living. Availability varies by city, so use the program links on this page to see exactly where each is offered.
How much does rehab cost in California?
Cost is driven by the type and length of treatment, not the state line — a few weekly outpatient sessions and a month of residential care sit at opposite ends of the price spectrum, and insurance network status moves the number more than geography does. See our cost of rehab guide for realistic ranges by level of care, and the free and low-cost rehab guide if paying out of pocket isn't an option.
Is every facility listed on this page licensed?
Yes, in the specific sense that matters: every listing comes from SAMHSA's National Directory, which only includes facilities licensed, certified, or approved by their state's substance use treatment authority. We don't add scraped or unverified listings. A license is the floor rather than the ceiling, though — our levels of care guides cover the questions worth asking any program before admission.
