How do you check a landscape irrigation license in Texas?

In Texas, landscape irrigation work falls under TCEQ, the Texas Commission on Environmental Quality, which issues landscape irrigator, irrigation technician and irrigation inspector licenses. Its landscape irrigation page links to a search of its licensing and registration records for landscape irrigators and irrigation companies, and a homeowner can use it as an optional public-record step.

Key facts

Where do you look up a Texas irrigator's license?

TCEQ's landscape irrigation page, read 22 October 2026, carries a link headed Search Licensing or Registration Information, with one line under it: "Find licensed or registered landscape irrigators and companies."

Source: TCEQ, Landscape Irrigation, read 22 October 2026.

TCEQ's page on license holder contact information explains why a result can show little more than a name and a license: "TCEQ does not publish any license holder information without the license holder’s consent." In our reading, a result with no business phone or address is not a finding on its own.

Who needs a TCEQ license to work on a sprinkler system?

TCEQ's licensing page for landscape irrigators, read 22 October 2026, opens its overview with this line: "A person may not sell, design, install, maintain, alter, repair, service or inspect an irrigation system—or consult in these activities—in this state, unless the person is licensed by the TCEQ."

Source: TCEQ, Landscape Irrigator, Irrigation Technician and Irrigation Inspector licenses, read 22 October 2026.

The same page adds a supervision line for the hookup itself: "While connecting an irrigation system to a water supply, a licensed irrigation technician must be under the direct supervision of a licensed landscape irrigator."

TCEQ's rules page names where the rules sit, in its own heading line: "Publications and rules for landscape irrigation under Title 30, Texas Administrative Code, (30 TAC) Chapter 344."

Some people are exempt, and the licensing page sends readers to one rule for the list: "View 30 TAC §30.129 for a list of all exemptions."

It adds a note for anyone who is exempt: "Note, a person who is exempt from the license requirements shall comply with the standards established in 30 TAC, Chapter 344".

What can each TCEQ irrigation license holder do?

TCEQ's licensing page describes three licenses. On the first it says: "Landscape Irrigator (LI) can sell, design, consult, install, maintain, alter, repair, or service an irrigation system, including the connection of such system to a private or public, raw or potable water supply, or any water supply."

Source: TCEQ, Landscape Irrigator, Irrigation Technician and Irrigation Inspector licenses, read 22 October 2026.

On the second: "Irrigation Technician (IT) can connect a landscape irrigation system to a water supply, including installing a backflow prevention device; and may maintain, alter, repair, service, or direct the installation of an irrigation system under the supervision of a licensed irrigator."

Source: TCEQ, Landscape Irrigator, Irrigation Technician and Irrigation Inspector licenses, read 22 October 2026.

Of irrigation inspectors, the page says: "They can inspect the irrigation system, determine if the irrigation system complies with the rule requirements, determine if the appropriate backflow prevention device is installed, provide test results to the water purveyor, and investigate complaints."

The page also keeps the inspector role apart from the trade, saying that "individuals who own an irrigation company, consult for an irrigation company, or work for an irrigation company may not simultaneously be an Irrigation Inspector."

TCEQ's landscape irrigation page adds a rule about a seal: "Each irrigator, upon being licensed with the commission, shall obtain a seal. Licensed irrigators shall not engage in any landscape irrigation services without physical possession of the seal and the license."

Source: TCEQ, Landscape Irrigation, read 22 October 2026.

On how long a license lasts, the licensing page says: "Occupational licenses are valid for three years then must be renewed with TCEQ."

Where do you take a complaint about a Texas irrigator?

TCEQ's complaint page, read 22 October 2026, starts with the local route: "Complaints regarding landscape irrigation need to be filed with the local program, if available."

Source: TCEQ, Make a Complaint About a Landscape Irrigator, read 22 October 2026.

It explains who runs those local programs: "Any city, town, county, special district, other political subdivision of the state, or water supplier may develop a landscape irrigation program and municipalities with a population of greater than 20,000 are required to adopt a landscape irrigation program."

Source: TCEQ, Make a Complaint About a Landscape Irrigator, read 22 October 2026.

TCEQ's own role comes after that: "The TCEQ Landscape Irrigation Program accepts complaints when there is no local jurisdiction."

The same page answers a question about getting money back: "No, TCEQ has no authority to recover any funds you lose because of the negligence of a license holder."

Source: TCEQ, Make a Complaint About a Landscape Irrigator, read 22 October 2026.

TCEQ's landscape irrigation page also describes a court route for unlicensed work: "Complaints against an unlicensed irrigator can now be filed in Municipal and Justice of the Peace courts, and law enforcement officers can issue a ticket; both citing a violation of Texas Occupational Code, Sec. 1903.256."

Source: TCEQ, Landscape Irrigation, read 22 October 2026.

What should you ask a Texas irrigator before work starts?

Ask which TCEQ license each person on your job holds, then look each one up in TCEQ's licensing and registration records. These questions are practical suggestions, not TCEQ rules.

  1. Ask whether the person holds a landscape irrigator or an irrigation technician license, and get the number in writing.
  2. If a technician will connect the system to your water supply, ask which landscape irrigator supervises that work.
  3. Search each number in TCEQ's licensing and registration records, and read the name and the license type on the result.
  4. Ask your city or water supplier whether it runs a landscape irrigation program, and whether your job needs a permit or an inspection.
  5. Keep a note of each number you searched, with your contract.
