How to Get Your Texas Landscape Irrigator License
In Texas, almost any professional irrigation work requires a license from the Texas Commission on Environmental Quality (TCEQ). Whether you’re operating as a Landscape Irrigator, Irrigation Technician, or Irrigation Inspector, you must hold the appropriate credential for the work you perform under Texas Occupations Code Chapter 1903.
Irrigation systems connect directly to a property’s drinking water supply. Improper installation can contaminate potable water or waste thousands of gallons through poor design and leaks. That’s why Texas requires professional licensing.
Texas Landscape Irrigator Licensing Process
Most irrigation contractors need the Texas Landscape Irrigator license. Here’s what the licensing process looks like:
Step 1 | Complete an approved training course |
Step 2 | Submit TCEQ application and fee |
Step 3 | Wait for approval letter (3 to 4 weeks) |
Step 4 | Schedule exam at a testing center |
Step 5 | Pass the licensing exam |
Step 6 | Renew every three years |
The sections below explain each step in more detail.
Can You Perform Irrigation Work Without an Irrigation License in Texas?
In almost every case, no.
Texas Occupations Code Chapter 1903 requires anyone who sells, designs, installs, maintains, alters, repairs, services, or inspects an irrigation system to hold the appropriate TCEQ license. This applies to the individuals actually performing regulated irrigation work. Specific exemptions are listed in 30 TAC §30.129. If you think an exemption may apply to your situation, verify it against the rule before assuming you’re covered.
Who Needs Which License?
| If you… | You need… |
|---|---|
| Own an irrigation business | Landscape Irrigator (LI) |
| Design irrigation systems | Landscape Irrigator (LI) |
| Install systems under a licensed irrigator | Irrigation Technician (IT) |
| Inspect systems for a municipality or water district | Irrigation Inspector (II) |
The Three License Types
The Landscape Irrigator (LI) is the license most contractors need. It covers selling, designing, installing, maintaining, altering, repairing, or servicing any irrigation system, including the connection to a water supply. This is what sprinkler contractors and irrigation business owners carry.
The Irrigation Technician (IT) is the field-worker credential. Technicians can handle hands-on installation and service work but must be under the direct supervision of a licensed irrigator when connecting to a water supply. The IT license is not sufficient to run your own irrigation business.
The Irrigation Inspector (II) is for people verifying permits and code compliance on behalf of municipalities or water districts. Inspectors can’t simultaneously own or work for an irrigation company.
Landscape Irrigator License Requirements
Texas doesn’t require a college degree or prior work experience. To qualify for the Landscape Irrigator license, you need to:
- Complete an approved Basic Irrigator Licensing Course
- Submit a TCEQ application and criminal history attestation
- Pay the $111 licensing fee
- Pass the licensing exam
The Basic Irrigator Licensing Course is offered by TCEQ-approved training providers across the state. The six-hour licensing exam covers system design, water conservation, backflow prevention, and Texas rules. The training is your best preparation.
The Application Process
Apply through TCEQ’s online licensing portal after completing training. You’ll submit your application, a criminal history attestation, and the $111 fee.
TCEQ reviews the application and mails an approval letter to the address on file. That takes about three to four weeks. Once your application is approved, TCEQ authorizes you to schedule the licensing exam. You can’t schedule until the letter arrives.
Texas Landscape Irrigator Exam
The Landscape Irrigator exam is computer-based, administered at approved testing centers across Texas, and runs six hours. Not every center can accommodate an exam that long, so confirm availability before booking.
You need at least 70 percent in each section to pass. Scores are available immediately when you finish. You can bring a non-programmable calculator; scratch paper is provided by the proctor.

| Item | Cost |
|---|---|
| Application fee | $111 |

Training providers and testing centers set their own prices, so total out-of-pocket costs vary. TCEQ posts current licensing fees at tceq.texas.gov.
How Long Does the Process Take?
| Step | Typical Timeframe |
|---|---|
| Complete training course | Varies |
| Application review | 3 to 4 weeks |

Texas Landscape Irrigator License Renewal
Your license is valid for three years. There’s no grace period. Once it’s expired, you’re not licensed.
To renew, you need 24 continuing education hours, a renewal application, a criminal history attestation, and $111. CE hours must be earned before the expiration date. TCEQ’s license lookup tool lets you track your current hours so nothing sneaks up on you.
The Inspector Conflict of Interest Rule
If you hold a Landscape Irrigator license and later pursue an Irrigation Inspector license, read the conflict of interest rules before applying. Under 30 TAC Chapter 30, Subchapter D, inspectors can’t own or work for an irrigation company at the same time. Holding both licenses is technically allowed, but you can’t use them concurrently.
Many Texas contractors include their license number on estimates and invoices. Cinderblock stores it once and automatically adds it to future customer documents, so you don’t have to enter it manually every time.
The Short Version
Complete a TCEQ-approved training course. Apply online, pay $111, wait three to four weeks for your approval letter. Pass a six-hour exam with at least 70 percent in each section. Your Texas Landscape Irrigator license is valid for three years. Renew with 24 CE hours and another $111. TCEQ’s irrigation licensing page has everything official in one place.
