Texas irrigation work is licensed by TCEQ. Here are the three license types, the $111 fee, the exam figures and the irrigator-in-charge rule for companies.
In Texas, irrigation work is licensed by the Texas Commission on Environmental Quality (TCEQ), not by a contractor board. If you sell, design, install, maintain, repair or inspect a landscape irrigation system, the state expects a TCEQ license in your name. A company that does not hold one itself has to put a licensed irrigator in charge of the work. This guide covers the three license types, the fees and exam figures TCEQ publishes, and the business rules that matter when you hire.
At a glance
- TCEQ issues three irrigation licenses: Landscape Irrigator, Irrigation Technician and Irrigation Inspector.
- The application fee is $111, and the exam requires at least 70 percent in each section.
- No education or work experience is required for the Landscape Irrigator license, but approved training is.
- Licenses last three years. Renewal needs continuing education: 24 hours for an irrigator, 16 for a technician.
- An unlicensed business owner must employ a licensed irrigator as irrigator-in-charge.
Who Must Be Licensed in Texas
Under Texas Occupations Code 1903 and the TCEQ rules in 30 TAC Chapter 30, a person may not sell, design, install, maintain, alter, repair, service or inspect an irrigation system, or consult on those activities, without a TCEQ license. Connecting a system to a water supply is covered too. For the overall Texas picture beyond irrigation, start with our Texas contractor license guide.
Some people are exempt. Licensed plumbers, engineers, architects and registered landscape architects are generally exempt when the irrigation work is incidental to their profession, and property owners working on their own homes are also exempt. Exempt persons must still follow the Chapter 344 irrigation standards.
The Three TCEQ Irrigation Licenses
| License | What it allows | Training | Continuing education |
|---|---|---|---|
| Landscape Irrigator | All irrigation work, including connecting to any water supply | Basic Irrigator Licensing Course | 24 hours |
| Irrigation Technician | Connecting to a water supply, plus maintaining, repairing and directing installation under a licensed irrigator | Irrigation Technician Course or Landscape Irrigator Licensing Course | 16 hours |
| Irrigation Inspector | Verifying permits, inspecting systems and backflow devices, investigating complaints | Landscape Irrigator course, backflow tester course and a water conservation or water audit course | 24 hours |
An Irrigation Technician who connects a system to a water supply must work under the direct supervision of a licensed Landscape Irrigator. Getting a Landscape Irrigator license expires any current Irrigation Technician license, so you hold one or the other.
Fees, Exam and Timeline
TCEQ lists the application fee at $111 for the initial license and $111 for renewal. The exam does not have a separate fee listed on the TCEQ licensing page. The Landscape Irrigator exam runs six hours, and not every computer-based testing center can accommodate an exam over four hours, so confirm before you schedule.
| Item | What TCEQ publishes |
|---|---|
| Application fee | $111 |
| Passing score | At least 70 percent in each exam section |
| Landscape Irrigator exam length | Six hours |
| Processing time | About 3 to 4 weeks, barring deficiencies |
| License term | Three years |
| Renewal fee | $111 |
Fees are set by the board or testing vendor and can change. Verify the current amount with the provider before you pay.
The Licensing Steps in Order
- Complete the required TCEQ training for the license you want.
- Submit the TCEQ application and a criminal history attestation.
- Pay the $111 application fee.
- Wait for the approval letter, which TCEQ sends by mail, then schedule the exam.
- Pass every section with at least 70 percent.
- Renew every three years with your continuing education hours, the renewal application, a criminal history attestation and the $111 renewal fee.
Renewals, Late Renewals and Expired Licenses
Under Texas Water Code 37.006, TCEQ must send written notice at least 60 days before a license expires. A license expired for 30 days or less can be renewed with a late fee of no more than 1.5 times the normal renewal fee. A license expired for more than 30 days cannot be renewed, so the holder reapplies for a new license, including any required exam. An expired license holder cannot perform licensed work until the license is renewed.
The Irrigator-in-Charge: Business Rules That Matter
This is the part most owners miss. Under 30 TAC 344.31, a business owner who is not licensed under Chapter 1903 is an exempt business owner, and that owner must employ a licensed irrigator as the irrigator-in-charge. The rules put clear duties on the business:
- The owner must make sure all irrigation services are supervised by a licensed irrigator.
- The owner must verify the license of every irrigator and technician working for the business.
- The irrigator-in-charge supervises all irrigation services of the business (30 TAC 344.35).
- A license number can be used at only one entity as the irrigator-in-charge (30 TAC 344.34).
- A licensed irrigator or technician must be on site at all times during installation (30 TAC 344.62).
A conflict rule also applies to inspectors. Under 30 TAC 30.120, someone who owns, consults for or works for an irrigation company may not serve as an Irrigation Inspector at the same time. People who hold both an irrigator or technician license and an inspector license must submit the Landscape Irrigation Program Conflict of Interest Affidavit with their renewal if they want to keep both current.
Penalties for Irrigation Work Without a License
Installing an irrigation system without a license is a Class C misdemeanor under Occupations Code 1903.256. TCEQ can also take disciplinary action under 30 TAC 344.21, including monetary penalties, suspension or revocation of a license. TCEQ may deny an application for reasons such as fraud, gross negligence or a record of continuing violations in the preceding five years.
Choosing Between the Irrigator and Technician License
The Irrigation Technician license is the shorter road. It needs no education or work experience, its training course is shorter in scope than the irrigator course, and it carries 16 renewal hours instead of 24. The trade off is authority. A technician works under a licensed irrigator, may not advertise irrigation services and may not act as the irrigator. A crew member who wants to run jobs, sign off on installs or be named irrigator-in-charge needs the Landscape Irrigator license.
Because earning the irrigator license ends any technician license you hold, plan the move for a renewal window rather than mid-term. Write down the date your current license expires, the date your continuing education is due and the date the exam center can seat a six hour exam. Those three dates decide your schedule more than any other factor.
When Your Irrigation Company Needs a Qualifier
The irrigator-in-charge rule is the same idea that drives qualifying agent placements in other trades: the company is allowed to operate because a credentialed person is on the payroll and answerable for the work. A full-time W-2 employee fills that seat. The credential has to belong to a person who works for the company, and the license number can serve only one entity.
If you own the business but hold no TCEQ license, you have two options. You can earn the Landscape Irrigator license yourself, or you can employ a licensed irrigator as your irrigator-in-charge. If you are weighing the second option across several trades or states, read what a qualifying agent does and how our Texas qualifying agent guide applies. Whether a given person can serve as irrigator-in-charge depends on that person holding the TCEQ license.
Irrigation also touches plumbing. Backflow devices and water connections are regulated, and Texas plumbers are exempt only when irrigation is incidental to their profession. See the Texas plumbing license guide if your company does both.
