DHCS Licensing vs Accreditation: How to Vet a California Treatment Center

If this is an emergency, call 911. For a mental health or suicide crisis, call or text 988. Severe alcohol or benzodiazepine withdrawal can be a medical emergency and belongs in an emergency department, not a residential facility. Vetting a program is for planning, not for an emergency in progress.

Every residential addiction treatment program in California says it is licensed. Almost all of them are, and the claim tells you less than families assume — because a DHCS licensed treatment center is licensed for something narrower than most people picture.

The license that the Department of Health Care Services issues to a residential program is, in the department’s own words, a license for residential nonmedical services. That single word — nonmedical — is the most important thing on the document, and it is the thing nobody reads. A licensed facility can run detox. It cannot practice medicine. The gap between those two statements is where most of the confusion about California treatment centers lives, and closing it is the difference between choosing a program that can safely manage a withdrawal and choosing one that will send your family member to an emergency room on night two.

Accreditation is a separate thing again, issued by private organizations rather than the state, and a program can hold one without the other. This guide explains what each credential actually certifies, what none of them certify, how to verify a California program yourself in about twenty minutes using the state’s own public records, and which red flags have an actual legal basis behind them rather than being general advice.

The Four Credentials a California Program Can Hold

People use “licensed,” “certified” and “accredited” interchangeably. In California they are four distinct things, issued by different bodies, covering different services, and meaning different things. A DHCS licensed treatment center might hold all four, or one.

1. A DHCS residential facility license

The Department of Health Care Services holds what its facility licensing page describes as “sole authority to license facilities providing residential nonmedical services to eligible adults” recovering from alcohol or other drug problems. A license is required if a residential facility provides any of the following: detoxification, individual sessions, group sessions, educational sessions, recovery or treatment planning, or incidental medical services. In practice, any residential program in the state offering real treatment must hold one, and holding it is what makes it a DHCS licensed treatment center.

What matters for vetting is the scope. This is a license to operate a residential nonmedical facility. It is not a license to operate a hospital, and it does not authorize the general practice of medicine on site.

2. DHCS AOD program certification

Certification runs under a different chapter of the Health and Safety Code and covers the program rather than the building. DHCS’s certification standards (version 1.0, October 2023) state that no entity may “establish, operate, manage, conduct, or maintain a program without first obtaining a current, valid certification,” subject to statutory exemptions. Certification covers outpatient and intensive outpatient programs as well as residential ones, and an adult residential program must be licensed before it can be certified.

Two details are worth knowing. Certification lasts two years and must be renewed, with the renewal application due at least 120 days before expiry. DHCS must conduct an on-site review at least once during each two-year period, and may make unannounced visits. So a current certificate means a state reviewer has been through the program at some point in the last two years — which is genuinely useful, and quite different from a one-time approval that never gets revisited.

What certification does not mean is a quality score. The standards describe certification as issued when the department determines an applicant is in compliance with the governing requirements, after any cited deficiencies have been corrected. It records compliance at the time of review. Marketing that presents “state certified” as an award is overselling it.

3. A DHCS Level of Care Designation or a residential ASAM Level of Care Certification

This is the newest layer and the most useful one for judging whether a program can handle a particular clinical situation. Health and Safety Code section 11834.015 requires DHCS to adopt the American Society of Addiction Medicine treatment criteria, or an equivalent evidence-based standard, as the minimum standard of care for licensed adult facilities, and the department has done so. Under the DHCS Level of Care Designation program, an adult facility must obtain at least one DHCS designation, at least one residential ASAM Level of Care Certification, or both, as a condition of remaining a DHCS licensed treatment center.

The designations cover four residential levels: 3.1 clinically managed low-intensity residential, 3.2 clinically managed residential withdrawal management, 3.3 clinically managed population-specific high-intensity residential, and 3.5 clinically managed high-intensity residential. A program designated only at 3.1 is a low-intensity residential setting. If someone needs clinically managed withdrawal management, 3.2 is the designation to look for, and a program without it is telling you something about its capability whether it means to or not.

The ASAM certification route is a private one. DHCS notes that the residential ASAM Level of Care Certifications were developed by ASAM in partnership with CARF International, and that an approved ASAM certification satisfies the state requirement. DHCS also makes a point of saying the two are separate, and that holding a DHCS designation does not guarantee eligibility for ASAM certification.

One nuance to ask about directly: DHCS designations are provisional until the department completes an on-site or virtual compliance review. A program can accurately say it holds a designation while that review is still outstanding. Asking whether the designation is provisional or has been through compliance review is a fair and revealing question.

4. Drug Medi-Cal certification

Separate again, and required for a program to be paid by Drug Medi-Cal. This one matters mainly to Medi-Cal members, and its absence is not a mark against a program that serves commercially insured and private-pay clients only. If you are on Medi-Cal, though, a program without it cannot bill your coverage no matter how good it is.

A DHCS reference document on licensing and certification for the Drug Medi-Cal Organized Delivery System maps the requirements by ASAM level. It dates from August 2017, so confirm current requirements with DHCS, but the structure it sets out still describes how the pieces fit together.

ASAM level	Service	State requirement for the setting
1	Outpatient	DHCS-certified outpatient program; no facility license required
2.1	Intensive outpatient	DHCS-certified intensive outpatient program
2.5	Partial hospitalization	DHCS-certified intensive outpatient program
3.1, 3.3, 3.5	Residential	DHCS residential license plus ASAM level of care designation
3.2-WM	Clinically managed residential withdrawal management	DHCS residential license with detox certification
1-WM, 2-WM	Ambulatory withdrawal management	DHCS-certified outpatient program with detox certification
3.7, 4 and their withdrawal management levels	Medically monitored and medically managed inpatient	Hospital-level licensure — not a DHCS residential license
OTP level 1	Narcotic treatment program	DHCS-licensed OTP, plus DEA and federal approval

Read the bottom rows of that table again if you are looking at medical detox. The levels of care that involve genuine medical management are not delivered under a residential nonmedical license. A program advertising “medical detox” from a residential facility is describing something narrower than the phrase suggests, and the next section explains exactly how narrow.

Not sure which level of care is the right one?

The designation a facility holds only matters against what someone actually needs. A clinical conversation settles that first, and the credential check follows from it.

What a DHCS Licensed Treatment Center Cannot Do

Incidental Medical Services is the only medical add-on, and it has hard limits

A DHCS licensed treatment center can apply to provide Incidental Medical Services. DHCS Information Notice 18-031 defines these as optional services provided by a health care practitioner, or by staff under a practitioner’s supervision, to address medical issues associated with detoxification, treatment or recovery. Authority comes from AB 848 of 2015, effective January 1, 2016.

An approved facility must provide six things: obtaining medical histories, monitoring health status, testing related to detoxification, recovery or treatment services, overseeing self-administered medication, and treating substance use disorders including detoxification. The notice sets operational requirements around them, including screening within 24 hours and a practitioner review of the resident assessment within 72 hours of admission. Practitioners must hold a valid California license and show proof of addiction medicine training.

Now the limits, which are the part that matters when you are choosing a program:

Incidental Medical Services may only be provided after DHCS approval. A facility providing them without approval, the notice says, “will be cited and subject to disciplinary action,” up to suspension or revocation of the license.
They expressly do not include general primary medical care, or any service required to be performed in a licensed health facility under Health and Safety Code sections 1200 or 1250. That exclusion is the legal line between a licensed residential program and a hospital.
A facility approved for Incidental Medical Services cannot order or stock bulk prescription medications. Residents self-administer, with oversight.
The services cannot be limited to particular residents or particular beds. They must be available to everyone in the facility.

So the question to ask is not “do you offer medical detox.” It is “are you approved by DHCS for Incidental Medical Services, and what is your physician coverage.” A program approved for Incidental Medical Services with a practitioner who has addiction medicine training is a meaningfully different proposition from one that is not approved and is using the phrase loosely.

A license is not a quality rating, and it is not an endorsement

Nothing in the licensing scheme assesses treatment outcomes, staff-to-client ratios beyond the minimum, the clinical model, or whether anyone actually gets better. It assesses compliance with the regulations governing the facility. A DHCS licensed treatment center can hold a clean license and deliver mediocre care, and the state record will not tell you. For the parts of the decision that licensing does not reach, our guide to choosing a treatment center covers the clinical and practical questions, and the general explainer on how to tell whether a rehab is licensed covers the mechanics outside California.

Accreditation: What CARF and the Joint Commission Actually Assess

Accreditation is voluntary, private and standards-based. An accreditor publishes a set of standards covering governance, clinical practice, documentation, staff qualifications, client rights and quality improvement; the program prepares against them; surveyors visit; and accreditation is awarded for a fixed term, with periodic resurvey. The two names you will see most often in addiction treatment are CARF International and the Joint Commission.

What that gives you, as someone vetting a program, is an independent read on whether the organization runs itself properly — whether treatment plans are individualized and documented, whether outcomes are measured at all, whether complaints go anywhere, whether staff hold the credentials the program claims. That is a real signal, and it covers ground the state license does not.

What it does not give you is a guarantee. Accreditors assess systems and documentation against standards at a point in time. A well-documented program is not automatically a good one, and an unaccredited program is not automatically a bad one — accreditation costs money and staff time, and some small, genuinely good programs skip it.

The line between voluntary and mandatory has blurred in California, though. Because an approved residential ASAM Level of Care Certification satisfies the state’s level of care requirement, and because those certifications were developed with CARF International, many California residential programs now hold a private certification as the route to meeting a state obligation. Our broader explainer on the accreditations rehabs hold covers the national picture.

	DHCS license	DHCS certification	Accreditation
Issued by	State of California	State of California	Private organizations (CARF, Joint Commission)
Mandatory?	Yes, for residential facilities providing treatment	Yes, for programs, with statutory exemptions	Voluntary, though the ASAM certification route now meets a state requirement
Covers	The facility and its physical operation	The program and its services	Governance, clinical practice, documentation, quality systems
Term	Ongoing, subject to enforcement	Two years, renewable	Fixed term with periodic resurvey
Tells you about quality?	No	Compliance at time of review only	Partially — systems and documentation, not outcomes

How to Verify a California Program Yourself

All of this is checkable, free, and mostly public. Five steps, in this order.

Step 1 — Find the facility in the state list

DHCS publishes a dataset of non-medical alcohol and drug recovery and treatment facilities, listed alphabetically by county, as SUD Recovery Treatment Facilities. It can be searched online or downloaded. If a residential program claims to be a DHCS licensed treatment center and does not appear in it, that is the end of the conversation, not the start of one.

Step 2 — Check the level of care designation

The DHCS Level of Care Designation page links a list of designated facilities. Confirm the program appears, and confirm it holds the level your clinician has recommended rather than simply some designation. Questions can go to LCDLOCDesig@dhcs.ca.gov.

Step 3 — Look at the violations record

DHCS publishes a treatment facility violations map under the accountability section of its facility licensing page. This is the step almost nobody takes and the one most likely to change a decision. A single old citation on an otherwise long record is normal. A pattern, or anything recent and serious, is worth asking about directly — and a program’s answer to “I saw this on the state violations map, can you walk me through it” is informative however it goes.

Step 4 — Confirm the Incidental Medical Services approval if detox is involved

The license itself reflects the approval, because DHCS issues a new license showing Incidental Medical Services once it approves an application and completes a site visit. Ask to see the current license rather than a logo on a website, and ask who the approved health care practitioner is.

Step 5 — Call the state if anything does not match

The DHCS Licensing and Certification Division answers general questions on (916) 322-2911 or at LCDQuestions@dhcs.ca.gov. If something looks wrong, the licensing and certification complaints page carries an online complaint form and a toll-free line on (877) 685-8333, with complaints also taken at sudcomplaints@dhcs.ca.gov. The division investigates complaints against licensed and certified programs and against registered or certified counselors, and says that where an unlicensed sober living home appears to be providing licensable services, “an investigation may be opened.”

One thing to know before you file: DHCS says complainants “will not be automatically notified of the outcome of a complaint.” You can request the outcome when the investigation closes, at which point the department begins a Public Records Act request on your behalf. Keep your own copy of whatever you submit.

Sober Living Homes Sit Outside This System Entirely

This is the single most common misunderstanding in California, and it has consequences. DHCS states plainly that it “does not license, certify, or investigate complaints against sober living/transitional living homes.” A home that provides housing and peer support, and does not provide alcohol or drug treatment services, is not a DHCS licensed treatment center and does not need to be: it needs no state license and has no state oversight. It may need local permits or business licenses from the city or county, and that is the extent of it.

That is not an argument against sober living, which does real work in supporting long-term recovery. It is an argument for understanding what you are buying. A sober living home is housing with structure and rules. If a home is in fact providing counseling sessions, treatment planning or detoxification, it has crossed into licensable territory and should hold a license — and DHCS may investigate if it does not.

Our overview of sober living and recovery housing explains how it fits into a recovery plan, and the guide to sober living house rules and expectations covers what a well-run home looks like from the inside.

Red Flags With an Actual Legal Basis

Most “red flags” lists are general advice. These four rest on specific California law or DHCS policy, which makes them worth more.

Anyone offering or taking a payment for sending you somewhere

California Health and Safety Code section 11831.6 provides that licensed facilities and certified programs — along with their owners, partners, officers, directors, shareholders holding at least a 10 percent interest, employees, workers, and registered or certified counselors — “shall not give or receive remuneration or anything of value for the referral of a person who is seeking” alcohol or drug recovery or treatment services. If a person who is helping you find treatment is being paid by the place they send you to, that arrangement is prohibited for the parties this section covers. Asking “are you paid by the facilities you refer to” is a legitimate question and the answer should be no.

“Medical detox” with no Incidental Medical Services approval

Covered above. The claim and the credential should match, and the credential appears on the license.

A program that will not show you the license

The license is a document. A program that deflects, sends a brochure instead, or points at an accreditation logo when you asked about the state license, is answering a different question than the one you asked. The state list and the designation list let you check independently in any case.

Level of care promises that outrun the designation

A facility designated at 3.1 describing itself as equipped for complex withdrawal is overstating its scope. The designation list is public and takes a minute to check.

Questions to Ask on the Admissions Call

Ten minutes of specific questions will tell you more than an afternoon of reading websites. These are the ones tied to what this page covers.

What is your DHCS license number, and may I have a copy of the current license?
Which DHCS Level of Care Designations do you hold, and has the compliance review been completed or is the designation still provisional?
Do you hold a residential ASAM Level of Care Certification, and from whom?
Are you approved by DHCS for Incidental Medical Services? Who is the approved health care practitioner, and what are their addiction medicine credentials?
Is your AOD program certification current, and when was your last state site review?
Are you accredited, by whom, and when does the accreditation expire?
Are you certified for Drug Medi-Cal?
Does anyone outside your organization receive payment for referring clients to you?
If someone needs a level of care above what you are designated for, what is your transfer arrangement and with which facility?

If you are making these calls on someone else’s behalf, our guide to supporting a loved one covers the part of this that is harder than the paperwork.

What Licensing Has to Do With Coverage

Credentials and coverage are connected but not the same. An insurer will generally not pay for a facility that is not appropriately licensed, and many plans require accreditation as a condition of network participation. But the clinical decision about whether a level of care is covered runs on a different track: for substance use treatment in California, it runs on the ASAM Criteria, which state law requires plans to use for level of care, continued stay and discharge decisions. Our page on California SUD parity sets out what the law requires, and the Anthem Blue Cross coverage guide works through one carrier in detail.

The practical overlap is this: the designation a facility holds and the level of care your plan has authorized need to match. A plan that has authorized clinically managed high-intensity residential care expects a facility designated for it. Where they do not line up, somebody is going to receive a bill, and it will not be the facility.

Frequently Asked Questions

What does it mean to be a DHCS licensed treatment center?

It means the Department of Health Care Services has licensed the facility to provide residential nonmedical services to adults recovering from alcohol or other drug problems. A license is required for a residential facility to provide detoxification, individual or group sessions, educational sessions, recovery or treatment planning, or incidental medical services. It is a facility license covering compliance with the regulations, not an assessment of treatment quality or outcomes, and it does not authorize the general practice of medicine on site.

Is DHCS licensing the same as certification?

No. Licensing covers the residential facility; certification covers the program and its services, runs under a different chapter of the Health and Safety Code, and applies to outpatient and intensive outpatient programs as well as residential ones. An adult residential program must be licensed before it can be certified. Certification lasts two years, requires renewal, and involves at least one on-site state review per two-year period.

Do all California rehabs have to be accredited?

Accreditation by a private body such as CARF International or the Joint Commission is voluntary. However, California requires licensed adult residential facilities to hold at least one DHCS Level of Care Designation or at least one residential ASAM Level of Care Certification, and the ASAM certifications were developed in partnership with CARF International. So many California residential programs do hold a private certification, as the route to satisfying a state requirement.

How do I check whether a California treatment center is licensed?

Search the DHCS SUD Recovery Treatment Facilities dataset, which lists non-medical alcohol and drug recovery and treatment facilities alphabetically by county. Then check the DHCS list of level of care designated facilities to confirm which levels the program holds, and review the DHCS treatment facility violations map. Ask the program for a copy of the current license as well, because the license itself shows whether Incidental Medical Services are approved.

What are Incidental Medical Services and why do they matter?

Incidental Medical Services are optional services provided at a licensed residential facility by a health care practitioner, or by staff under a practitioner’s supervision, to address medical issues associated with detoxification, treatment or recovery. They require DHCS approval, which is reflected on the license. They expressly exclude general primary medical care and anything that must be performed in a licensed health facility, and an approved facility may not stock bulk prescription medications. If a residential program advertises medical detox, the approval is the thing to verify.

Does DHCS license sober living homes?

No. DHCS states it does not license, certify, or investigate complaints against sober living or transitional living homes. A home that provides housing and peer support without providing treatment services needs no state license, though it may need local permits or business licenses. If a sober living home is providing licensable services such as counseling or detoxification, DHCS says an investigation may be opened.

What do the DHCS level of care designations 3.1, 3.2, 3.3 and 3.5 mean?

They correspond to ASAM residential levels: 3.1 is clinically managed low-intensity residential services, 3.2 is clinically managed residential withdrawal management, 3.3 is clinically managed population-specific high-intensity residential services, and 3.5 is clinically managed high-intensity residential services. A facility must hold at least one. Check that the program holds the level your clinician recommended, not merely that it holds one, and ask whether the designation is still provisional pending a DHCS compliance review.

How do I file a complaint about a California treatment facility?

Use the DHCS Licensing and Certification Division complaint form online, or by mail or fax. The toll-free complaint line is (877) 685-8333, the public line is (916) 322-2911, and complaints are also taken at sudcomplaints@dhcs.ca.gov. DHCS investigates complaints against licensed and certified programs and against registered or certified counselors. Complainants are not automatically notified of the outcome but may request it when the investigation closes.

Does a licensed facility have to accept my insurance?

No. Licensing and certification are state requirements; network participation is a private contract between the facility and the insurer, and Drug Medi-Cal certification is separate again. A program may be fully licensed and still be out of network for your plan. Check the credential and the network status as two separate questions.

Is an unaccredited program a bad program?

Not necessarily. Accreditation costs money and staff time, and some small programs that deliver good care do not pursue it. Its absence means you have less independent information and should ask more questions yourself — about clinical model, staff credentials, how treatment plans are individualized, and whether outcomes are tracked. Its presence means an outside body has reviewed the program’s systems and documentation against published standards, which is useful but is not a guarantee of results.
