How to open a rehab center

Pick the kind of rehab center first

"Rehab center" covers at least six different businesses. Each has its own license, staffing floor and payers, so place yours in this table before you look at buildings. The Texas column is the rule we work under every day; the timing column is from our Texas roadmaps where it says so, and from the rule where it cites one.

Program type	License in Texas	Typical time	Our guide
Outpatient, IOP or PHP (clients live at home and come for groups and counseling)	HHSC chemical dependency treatment facility (CDTF) license, 26 TAC 564	First admission in about 6 months on our roadmap's earliest path; nine to twelve months to a full caseload of insured clients	Start an IOP or PHP in Texas; any state
Detox (withdrawal management, residential or ambulatory)	The same CDTF license with detoxification services, plus 26 TAC 564.902	HHSC has 45 days to review the packet, 45 to inspect and 45 to issue; you have 6 months from filing to show compliance (26 TAC 564.403). The building usually sets the pace	Start a detox center in Texas
Residential treatment (clients live on site)	The CDTF license with residential services, plus 26 TAC 564.903 and the subchapter L building rules	The same HHSC windows; zoning, build-out and the fire inspection come first	Start a residential treatment center in Texas
Methadone clinic (opioid treatment program, OTP)	HHSC narcotic treatment program license (26 TAC 563), plus SAMHSA certification, accreditation and a DEA registration	SAMHSA asks for 45 days to decide a provisional application; accreditation is the long pole	Start an OTP in Texas
Mental health clinic or mental health IOP	An outpatient clinic: no facility license that we've found, each clinician is licensed. A mental health IOP or PHP: unsettled, so get HHSC's answer in writing	A clinic opens in about 17 weeks on our group-practice roadmap; a mental health IOP's first admission in about 6 months	Open a mental health clinic; mental health IOP licensing
Sober living home (recovery residence, no treatment on site)	None. Certification is voluntary, through TROHN, but a house that isn't accredited can't receive state money	A house opens in about 11 weeks on our roadmap, with certification after it's running	Open a sober living home in Texas

Most rehab centers end up running more than one of these: a detox that steps clients down to residential, a residential program with an IOP next door, an IOP that partners with a sober living home. Plan the first one well and add the next when it's paying its way; our guide to adding a level of care covers the second step. If you're not sure where the line between PHP, IOP and outpatient sits, read IOP vs. PHP vs. outpatient.

The steps, in order, for any rehab center

The order matters more than any single step. The license comes before insurance contracts, and many contracts come only after accreditation, which needs charts from clients you've already served. Every program launch we run follows this sequence:

1. Choose the program type, the population and the payers. Adults or adolescents, substance use or mental health or both, and which insurance plans people in your area actually carry. Check what those plans pay for that level of care and how many clients a day you'd need to break even.
2. Hire a health-care attorney and a CPA. Ownership, physician roles and how anyone who brings in clients is paid are legal questions to settle before you sign anything.
3. Budget for the gap, not just the build-out. Payroll and rent run for months before the first insurance payment. Our guide to what it costs to open a rehab center breaks it down by program type.
4. Form the business. Entity, EIN, an organization NPI (Type 2), and the same legal name, letter for letter, on every document.
5. Find a building the city approves for that use, in writing, before you sign. A residential or detox program also has to meet the state's building rules for people who sleep there. Sign the lease with a way out if zoning or the license falls through.
6. Write the operational plan and policy manual against your state's rule, line by line, and design the clinical program on the ASAM Criteria most payers use.
7. Hire and train the team to the staffing floors for your program type, with a credential file for every person (staff credential file checklist).
8. Apply for the state license when you're close to ready, pass the inspection, and don't admit anyone until you have it in writing.
9. Enroll with Medicaid and contract with each insurance plan as a facility. How plans decide is in insurance contracts for treatment centers; until a contract is effective, single case agreements can bridge the gap.
10. Open, then get accredited. The Joint Commission and CARF survey programs that are already serving clients; see accreditation for new programs.
11. Build referrals the legal way. Never pay or accept anything of value for a client referral (patient brokering laws), and plan the website and ads to pass review (marketing a treatment center).

How to open a rehab center in Texas

Texas is simpler than most states in one way: a single HHSC license, the chemical dependency treatment facility (CDTF) license under Health and Safety Code chapter 464 and 26 TAC chapter 564, covers outpatient, IOP, PHP, residential and detox. Your application says which services you'll provide at which site, and each service adds its own section of the rule. What that means in practice:

Texas rule	What it means for your rehab center
No treatment before approval	An applicant may not provide chemical dependency treatment until HHSC gives written notice of approval (26 TAC 564.403). There is no "open and apply" path.
The 6-month clock	After you file, you have 6 months to show HHSC you meet the rules or the application is denied. File when the site, policies and staff files are close to ready, not before.
The fee scales with sites and beds	$1,200 for a two-year license, plus $125 for each additional site and $35 per residential bed (26 TAC 564.408). A 16-bed residential program at one site: $1,760.
Each service adds a rule	Detox adds 564.902 (a physician medical director, a nurse on duty at least 8 hours a day, a physician or designee on call 24 hours). Intensive residential adds 564.903 (an average of at least 30 hours of services per client a week, direct-care ratios of 1:16 awake and 1:32 asleep, caseloads of no more than 10).
Adding services later	Under 564.405, a licensed program notifies HHSC in writing before adding outpatient or day treatment, and applies and gets written approval first for residential, detox and added beds (adding a level of care).
Who counsels	Counseling is provided by or under qualified credentialed counselors (QCCs), such as LCDCs; see staffing requirements in Texas.
Faith-based programs	Programs that use only nonmedical methods have their own path under chapter 464, subchapter C, and are exempt from the CDTF license, with their own requirements.
Medicaid needs the license	TMHP has said Texas Medicaid SUD treatment may be given only in a licensed CDTF (TMHP notice), and most members are in managed care, so you also contract with each plan in your area (Texas Medicaid credentialing).

Three more Texas specifics catch new owners:

• Corporate practice of medicine. Under Texas's strong corporate practice of medicine doctrine, a business owned by non-physicians generally can't employ physicians to practice medicine. If your rehab center will have a medical director or prescribers, which every detox does, your attorney sets up the structure first (hiring a medical director).
• The Patient Solicitation Act (Occupations Code chapter 102) bans paying or accepting anything for securing patients, whatever the payer, self-pay included.
• Methadone is a different license. A detox that wants methadone tapers beyond the federal 3-day exception is opening an opioid treatment program, with its own HHSC license under chapter 466.

The application, form by form, is in our Texas CDTF license guide, and every rule in the chapter is matched to the document that proves it in the 26 TAC 564 requirements map. What changes from Houston to the Panhandle (zoning, the Medicaid plans and the local public system) is in opening a program in Texas, by city.

What changes by program type

Detox

A detox is a 24-hour medical service. Texas's floor is a physician medical director, a history and physical within 24 hours of admission, a licensed nurse on duty at least 8 hours every day and a physician or designee on call around the clock (26 TAC 564.902); medically monitored programs usually staff nurses on every shift. One post covered around the clock is 168 hours a week, about 4.2 full-time staff before anyone takes time off. Storing benzodiazepines or buprenorphine needs a DEA registration for the site, and methadone outside an OTP or hospital is limited to 3 days while arranging a referral (21 CFR 1306.07(b)). Details: how to start a detox center in Texas.

Residential treatment

Residential adds the hours, ratio and caseload rules above, building rules for people who sleep on site, and one number that shapes the whole business: 16 beds. Federal Medicaid defines an institution for mental diseases (IMD) as a facility of more than 16 beds primarily treating mental diseases, substance use disorders included (42 CFR 435.1010), and generally won't pay for adults 21 to 64 in one. That's why so many rehab centers have 16 beds. Details: the IMD section of our residential guide.

PHP, IOP and outpatient

The fastest rehab center to open, and the one we run ourselves. Most payers expect about 20 hours a week for PHP and at least 9 for adult IOP. Medicare pays for PHP and, since 2024, IOP only through hospitals, community mental health centers and a few other provider types (CMS, CY 2024 outpatient rule), so a freestanding program plans its payer mix without Medicare. Details: how to start an IOP or PHP in Texas and how to start a PHP.

Methadone clinic (OTP)

Four approvals from four bodies: SAMHSA certification under 42 CFR Part 8, accreditation by a SAMHSA-approved body, a DEA narcotic treatment program registration renewed every year, and the state license. They depend on each other, so the filing order matters. Details: how to start an OTP in Texas. Programs that only want buprenorphine don't need an OTP; see adding MAT to a program.

Sober living

A recovery residence provides housing, not treatment. Texas doesn't license recovery residences; certification is voluntary through TROHN, which certifies to the NARR standard, and since September 1, 2025 a Texas recovery house that isn't accredited can't receive state money. A house can't provide treatment on site without a facility license. Details: how to start a sober living home and the TROHN certification guide.

Opening a mental health facility or clinic

Mental health is licensed differently from substance use. In Texas, an outpatient therapy and psychiatry clinic is built on its clinicians' licenses (counselors, social workers, marriage and family therapists and psychologists through the Behavioral Health Executive Council; physicians through the Texas Medical Board; nurse practitioners through the Board of Nursing), and we haven't found a facility license for a freestanding clinic. A crisis stabilization unit or private psychiatric hospital is licensed by HHSC under Health and Safety Code chapter 577. A mental-health-only IOP or PHP sits in between: it doesn't fit the CDTF license, which requires a substance use diagnosis, and as far as we've found Texas has no license written for it, so get HHSC's answer for your model in writing. Our guides: how to open a mental health clinic in Texas, licensing a mental health IOP or PHP and, if you'll treat both, running a dual diagnosis program.

Opening a rehab center in another state

There is no national rehab license. Each state decides who licenses or certifies treatment programs, and substance use and mental health programs are often regulated by different offices. Two examples from our state guides: California's Department of Health Care Services licenses residential facilities and certifies outpatient programs (DHCS program certification), and Florida's Department of Children and Families licenses each component of a substance use program under chapter 397 and rule 65D-30.

1. Find the agency. SAMHSA lists each state's single state agency for substance use services in its SSA directory. It's usually the licensing agency, or knows who is.
2. Read the rule for your program type: the definitions, staffing and credentials, records and the building section.
3. Ask in writing which license each service needs, what the application costs, whether there's an inspection before you serve clients, and whether anything sits on top (a certificate of need in some states, adolescent approvals, medications on site).

Our state guides name the agency, the rule, the fees and the Medicaid plans for an outpatient program in Alabama, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida, Georgia, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nevada, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Tennessee, Utah, Virginia, Washington, West Virginia and Wisconsin. Start there, then ask that agency which license residential, detox and methadone need in that state. The order of the work and what payers expect are the same everywhere; see how to start an IOP in any state.

Federal rules that apply in every state

Rule	Who it reaches
42 CFR Part 2	Federally assisted programs that hold themselves out as treating substance use disorders: their records and consents. See the Part 2 guide
42 CFR Part 8	Any program dispensing methadone for opioid use disorder
DEA registration	Each location where controlled substances are stored or dispensed (21 CFR 1301.12): every detox that stores or gives controlled medications, and every OTP
The IMD exclusion	Residential and detox facilities of more than 16 beds that want Medicaid for adults 21 to 64
EKRA, 18 U.S.C. 220	Treatment facilities, recovery homes and labs: no payment for referrals, under any payer
TRICARE accreditation	Residential SUD facilities must be accredited by the Joint Commission, CARF, COA or another approved body (TRICARE Policy Manual, chapter 11, section 8.1), and so must IOPs and PHPs

What it costs to open a rehab center

It depends most on whether clients sleep there. Our projection model's example outpatient program (PHP and IOP, 24 clients at full census) needs $111,000 in one-time costs and about $258,000 in cash in all before it pays for itself, and its 8-bed sober living example about $14,400 to open, before attorney and consulting fees. Detox and residential cost far more, mostly in round-the-clock staff and the building. The line-by-line version, with every government fee we can source and the staffing math for 24-hour programs, is in how much it costs to open a rehab center.

Questions

How do you open a drug rehab center?

Pick the program type (detox, residential, PHP, IOP, outpatient or a methadone clinic), form the business, lease a building the city approves for that use, get your state's facility license before treating anyone, then contract with insurance plans as a facility and seek Joint Commission or CARF accreditation once you're serving clients.

Do you need a license to open a rehab center?

For treatment, yes, in nearly every state. In Texas it's the HHSC chemical dependency treatment facility license for outpatient, IOP, PHP, residential and detox, and a narcotic treatment program license for methadone. A sober living home that provides no treatment isn't licensed in Texas.

How long does it take to open a rehab center?

On our Texas roadmap an outpatient program's first admission comes in about 6 months on the earliest path, and a full caseload of insured clients takes nine to twelve months, because insurance contracts follow the license. Residential and detox depend on the building: zoning, build-out and the fire inspection come before the state license.

How do I open a rehab center in Texas?

Apply to HHSC for a chemical dependency treatment facility license naming the services you'll provide at each site, and meet 26 TAC 564 plus 564.902 for detox or 564.903 for residential. File only when you're nearly ready, because you have 6 months to show compliance, and don't admit anyone until HHSC approves in writing. Then enroll with TMHP and contract with each plan.

Can I open a rehab center without being a doctor or counselor?

Yes, many owners aren't clinicians. You'll need qualified clinical leadership the license names, and in Texas the corporate practice of medicine doctrine shapes how a non-physician-owned center works with its medical director, so settle the structure with a health-care attorney first.

Why do rehab centers have 16 beds?

Because federal Medicaid treats a facility of more than 16 beds that primarily treats mental illness or substance use as an institution for mental diseases, and generally won't pay for adults 21 to 64 there.

What's the easiest kind of rehab center to open?

An outpatient program or IOP: no beds, no 24-hour staffing and a smaller building. A sober living home is simpler still, but it isn't treatment and can't bill insurance for care.
