Texas Landscaping License Requirements (2026)
By Gabriel Giner, Editor · Reviewed 2026-05-01 · CLR Editorial Review Desk
Texas does not issue a state-level landscape contractor trade license, but TWO state credentials are mandatory depending on scope: (1) any landscape irrigation installation, design, or service requires a Licensed Irrigator (LI) license from the Texas Commission on Environmental Quality (TCEQ) under 30 TAC Chapter 344 and Texas Occupations Code Chapter 1903, and (2) any commercial pesticide application requires a Commercial Pesticide Applicator license from the Texas Department of Agriculture (TDA) Pesticide Section under Texas Agriculture Code Chapter 76. Major cities (San Antonio, Austin, Dallas, Houston) require local landscape contractor registration and enforce drought-stage watering rules.
The Licensing Authority
Licensing for this trade is governed by Texas Commission on Environmental Quality (irrigation) and Texas Department of Agriculture (pesticide) (TCEQ / TDA), the agency that issues and regulates the credential under Texas Occupations Code Chapter 1903 (Landscape Irrigators), 30 TAC Chapter 344, Texas Agriculture Code Chapter 76. TCEQ licenses landscape irrigators, irrigation technicians, and irrigation inspectors. TDA licenses commercial pesticide applicators. Texas does not license landscape installation contractors at the state level; cities and counties may impose local registration.

Answers to Common Questions
Does Texas license landscape contractors?
Not for installation. Texas requires the TCEQ Licensed Irrigator for any irrigation work and the TDA Commercial Applicator for any pesticide work, but pure planting/sod/mulch work needs only local registration.
Is the TCEQ irrigator license really required?
Yes. Texas Occupations Code §1903.251 makes any irrigation design, installation, or service without an LI license a violation with civil penalties up to $5,000 per day.
What is Category 3A?
TDA Category 3A — Ornamental and Turf — covers commercial pesticide application to landscape ornamentals, turf, and trees. Required for any commercial spraying.
Are there drought watering restrictions?
Yes. San Antonio (SAWS), Austin (Austin Water), Dallas, and Houston all enforce drought-stage watering rules with day-of-week restrictions and time-of-day limits.
How often does the TCEQ LI license renew?
Annually. Renewal requires 8 CEU hours per year.
