Requirements
Texas HVAC plumbing licensing is administered by TDLR (the Texas State Board of Plumbing Examiners merged with TDLR in 2019). To obtain a Journeyman Plumber license, you must accumulate the required hours of on-the-job plumbing experience under a licensed Journeyman or Master Plumber. Many applicants follow a two-step path: first obtaining a Tradesman Plumber-Limited license after approximately 4,000 hours, then continuing to accumulate hours toward the full Journeyman license. After completing the required hours, you apply to TDLR, pass the PSI written exam, and pay the license fee.
Steps to Apply
- 1
Register as a Plumber's Apprentice with TDLR and begin working under a licensed Journeyman or Master Plumber.
- 2
Accumulate the required hours of on-the-job plumbing experience (approximately 4 years / 8,000 hours).
- 3
Optional intermediate step: apply for a Tradesman Plumber-Limited license after approximately 4,000 hours, which allows limited independent work while continuing toward Journeyman.
- 4
Submit your Journeyman Plumber application to TDLR with documentation of your work history verified by your supervising licensed plumber.
- 5
Schedule and pass the PSI Journeyman Plumber written exam. Study the Texas Plumbing License Law, plumbing code, and calculations.
- 6
Pay the TDLR Journeyman Plumber license fee (~$43) and receive your license. Your license must be renewed annually.
