Master Plumber License (Journeyman / Tradesman precede)
Texas licenses plumbers individually through the Texas State Board of Plumbing Examiners (TSBPE) — one of only a few boards not folded into TDLR. Plumbers go through a formal apprentice → tradesman → journeyman → master path, and only a Master Plumber (holding a Responsible Master Plumber designation) can operate a plumbing company.
Step-by-step: how to become a licensed Texas plumber
The full path — apprentice to Responsible Master Plumber — takes 8+ years. Journeyman is the practical working license and is achievable in 4 years with steady work.
- Register as a Plumbing Apprentice with TSBPE ($25/year). Must work under a Master or Journeyman.
- Optional: earn Tradesman Plumber-Limited license after 4,000 hours (~2 years) and a passing exam. Lets you perform residential plumbing under general supervision but not commercial.
- Complete 8,000 hours (4 years) of documented plumbing work to qualify for the Journeyman exam.
- Pass the Journeyman Plumber exam through PSI: closed-book, 100 questions, 5 hours, 70% to pass.
- Work 4 more years (8,000 hours) as a Journeyman before you can sit for the Master exam.
- Pass the Master Plumber exam: closed-book, 100 questions, 5 hours, 70%. Add the Responsible Master Plumber designation (extra exam) to legally run a company.

Can I own a plumbing business in Texas without being a Master Plumber?
You can own the LLC or corporation, but you cannot legally offer plumbing services without a Responsible Master Plumber (RMP) as your qualifying agent. The RMP must be a full-time employee (or the owner). If your RMP quits, you have 60 days to designate a replacement or the state suspends the company's ability to pull permits.
Does Texas have plumbing license reciprocity?
TSBPE has journeyman-level reciprocity with Louisiana, Arkansas, and Oklahoma if you've held an equivalent license there for 3+ years. Master and RMP licenses always require Texas exams. Experience from any state counts toward the hours requirement if properly documented with W-2s and letters from prior employers.
What's the difference between a Journeyman and a Tradesman Plumber-Limited in Texas?
Journeyman covers all plumbing work (residential and commercial) under a Master's responsible supervision. Tradesman Plumber-Limited is capped at residential only, and the supervising Journeyman or Master must be reachable but doesn't need to be on-site. Tradesman is a good stepping-stone for apprentices who don't yet have 8,000 hours toward Journeyman.
Can a general contractor do plumbing work in Texas?
No. Texas Occupations Code Chapter 1301 requires a licensed plumber for any work involving water supply, drainage, venting, gas piping, or medical gas. General contractors must subcontract to a licensed plumbing company (with a Responsible Master Plumber). Unlicensed plumbing work is a class A misdemeanor with fines up to $4,000 per violation.
