The license is statewide

HHSC licenses substance use programs as chemical dependency treatment facilities under Health and Safety Code chapter 464 and 26 TAC 564, and no Valley city adds a treatment license. As of October 2026 the fee under 26 TAC 564.408 is $1,200 plus $125 per additional site. Programs here often plan a second site, McAllen and Harlingen or Brownsville, because the Valley is long and clients won't drive its length. Each address needs its own license and its own certificate of occupancy from its own city. The forms are in our CDTF license guide, the rules in 26 TAC 564 in plain English, and the whole sequence in how to start an IOP or PHP in Texas.

Which city's permit office?

The first question is jurisdiction. McAllen, Edinburg, Mission, Pharr, Weslaco, Harlingen and Brownsville each run their own zoning, permits and inspections, and addresses outside city limits answer to the county.

In McAllen, anyone who plans to build, alter or change the occupancy of a building must first apply to the Building Permits and Inspections Department and get the required permits (City of McAllen), and the city's commercial permit application says improvements can't be occupied until a certificate of occupancy is issued (McAllen commercial permit application). Turning an office or retail suite into group rooms is a change of occupancy, so expect permits and inspections even with little construction.

Wherever you are, ask the city in writing before you sign:

1. Is an outpatient substance use treatment program allowed at this address, and under what zoning approval?
2. Does the existing certificate of occupancy cover our use and occupant load, or is this a change of occupancy?
3. What permits and inspections will the build-out need, and how long are reviews running?
4. What does the fire marshal check before we open?

Lease with a contingency for the certificate of occupancy and the HHSC license. Every site step is on our Texas IOP opening checklist.

Medicaid plans in the Hidalgo service area

After the HHSC license, enroll with TMHP, then credential with each plan. TMHP has said Medicaid SUD treatment may only be delivered in a licensed chemical dependency treatment facility (TMHP notice).

Program	Who it covers	Plans in the Hidalgo service area
STAR	Most children, pregnant women and some families	Driscoll, Molina, Superior, UnitedHealthcare
STAR+PLUS	Adults with disabilities and adults 65 and older	Molina, Superior, UnitedHealthcare
CHIP	Children in families above Medicaid income	Molina, Superior

• Three plans sit in both adult programs. Molina, Superior and UnitedHealthcare are each listed in STAR and STAR+PLUS here, so an adult program can pick two or three and cover both. Start with the ones your referral sources' patients carry. Our guides: Molina, Superior HealthPlan, UnitedHealthcare and Optum.
• Driscoll Health Plan is the regional plan, tied to Driscoll Children's Hospital, and serves the Valley and the Coastal Bend in STAR. It matters most for adolescent programs.
• The service area is bigger than the Valley. Laredo (Webb County) and Eagle Pass (Maverick County) are in the same Hidalgo service area, so a plan contract here covers members there too if you open a second site.

The process is in our Texas Medicaid credentialing guide and every area's line-up in Texas Medicaid health plans by service area. Our credentialing service files and follows each application.

Spanish-first services and the border

• Run the program in Spanish, not just the postings. 26 TAC 564.506 requires the client bill of rights, HHSC's complaint information and the grievance procedure posted in English and a second language. In the Valley, that's the floor: hire bilingual counselors, translate the intake packet, consents and treatment plan forms, and run Spanish-language groups when the census supports them. Our intake packet checklist lists every form to translate.
• Document in the language you can audit. Notes written in English with services delivered in Spanish are common; say in the note which language the session was in, and keep interpreter use documented.
• Clients without Texas coverage. Some clients live in Mexico or carry coverage that won't pay a Texas program. A Texas Medicaid contract covers Texas Medicaid members only. Verify benefits before admission (our sister site's VOB checklist), and publish a self-pay rate if you'll offer one.
• Records across the border. Sharing SUD records with a provider in Mexico still needs a consent that meets 42 CFR Part 2.

Cameron and Willacy: the coast

Hidalgo County is inland, but Cameron and Willacy counties are in TDI's designated catastrophe area, where most new construction, roof work, major repairs and alterations need inspection by a TDI-appointed engineer and a certificate of compliance (TDI windstorm inspections). A Brownsville or Harlingen build-out with exterior work should budget for it. Valley-wide, hurricane season runs June 1 to November 30 and heavy rain floods low streets; check the address on FEMA's flood maps and write closures and telehealth continuation into your plan. Comply's emergency operations plan guide covers it.

The local landscape

Earn referrals with quick assessments, bilingual staff and honest updates. Paying or giving anything of value for referrals is illegal under the Texas Patient Solicitation Act and EKRA (patient brokering laws, explained). We never arrange referrals.

• Tropical Texas Behavioral Health is the local mental health and IDD authority for Cameron, Hidalgo and Willacy counties (HHSC LMHA directory), and its Edinburg office runs OSAR for Region 11, the program that screens people and links them to state-funded substance use treatment (HHSC OSAR page). It also offers its own substance use services, so know what it does and where you fit next to it. Clients from Starr, Webb or the other counties have their own authorities, listed in the same directory.
• Hospitals. The Valley's hospital systems discharge patients who need a step down. Case managers want your levels of care, accepted plans, Spanish capacity and assessment times.
• Courts and probation. If the county runs a drug court or other specialty court under Government Code chapter 123, reports to it go only with the client's Part 2 consent.
• Clinics and counselors refer clients who need more than weekly therapy. A Spanish and English one-pager with schedules and plans does more than lunches. Legal marketing is in how to market a treatment center.

The order of work in the Valley

Step	Valley detail	Typical time in our roadmap
1. Program model and budget	Levels of care, Spanish groups, one site or two, payers. Run the break-even calculator.	1–2 months
2. Site search	Which city; zoning; change of occupancy; windstorm rules in Cameron and Willacy	about 30 days
3. Lease with a contingency	Out if the certificate of occupancy or license fails; free rent for the build-out	about 3 weeks
4. Build-out	Permits from that city; translate your forms while you wait	about 6 weeks
5. Certificate of occupancy and fire inspection	Keep both for HHSC and the accreditor	about 3 weeks
6. HHSC license and inspection	Bilingual postings in place before the inspection	about 2–3 months
7. Facility contracts	TMHP, then two or three of Molina, Superior and UnitedHealthcare, plus Driscoll for adolescents, and commercial plans	about 90 days each

The times are the planning figures in our own launch roadmap, not promises. On that roadmap the first admission comes about 6 months after kickoff. Costs are in how much it costs to start an IOP.

Questions

Which Medicaid plans serve McAllen and the Rio Grande Valley?

HHSC's August 2026 map lists Driscoll, Molina, Superior and UnitedHealthcare for STAR, and Molina, Superior and UnitedHealthcare for STAR+PLUS, in the Hidalgo service area: Cameron, Duval, Hidalgo, Jim Hogg, Maverick, McMullen, Starr, Webb, Willacy and Zapata counties.

Who is the local mental health authority in the Valley?

Tropical Texas Behavioral Health, for Cameron, Hidalgo and Willacy counties. Its Edinburg office runs the region's OSAR program for state-funded substance use treatment.

Where do I get a certificate of occupancy in McAllen?

From the City of McAllen's Building Permits and Inspections Department. Edinburg, Mission, Pharr, Harlingen, Brownsville and the other cities each have their own office.

Do we have to offer services in Spanish?

Texas requires key postings in English and a second language under 26 TAC 564.506. Beyond the rule, a Valley program without Spanish-speaking counselors and forms will struggle to fill groups.

How long does it take to open an IOP in the Rio Grande Valley?

Plan on nine to twelve months to a full caseload of insured clients. Pick the plans first, because credentialing usually takes longer than the license.

Other Texas cities: Corpus Christi, San Antonio, El Paso, and every city on opening a program in Texas, by city.
