Dreaming of a stable, in-demand career with strong earning potential? You’re not alone. Many Americans are turning to skilled trades like plumbing—and Texas offers one of the clearest paths to licensure in the country. If you’ve ever searched “how to become a licensed plumber in Texas,” you’re in the right place. This guide breaks down every requirement, timeline, and tip you need to succeed—no guesswork, just facts from the field.
Why Get a Plumbing License in Texas?
Plumbing isn’t just about fixing leaky faucets—it’s a licensed profession that ensures public health and safety. In Texas, only licensed plumbers can legally perform plumbing work on residential or commercial properties. Working without a license can result in fines up to $5,000 per violation (Texas Occupations Code §1301.451).
Plus, the demand is soaring:
- The U.S. Bureau of Labor Statistics projects 15% job growth for plumbers nationwide through 2032—much faster than average.
- In Texas alone, over 5,000 new plumbing jobs are expected by 2026 (Texas Workforce Commission).
- Licensed plumbers in Texas earn $52,000–$85,000 annually, with master plumbers often exceeding $100K.
A license isn’t just a legal requirement—it’s your ticket to credibility, higher pay, and business ownership.
Step 1: Meet Basic Eligibility Requirements
Before you even pick up a wrench, ensure you qualify:
- Be at least 18 years old
- Have a high school diploma or GED
- Be a U.S. citizen or legal resident
- Pass a background check (felonies may disqualify you—check with the Texas State Board of Plumbing Examiners)
💡 Pro Tip: While not required, taking high school courses in math, physics, or shop class gives you a head start on pipe calculations and blueprint reading.
Step 2: Complete a Plumbing Apprenticeship
Texas requires 4,000 hours (about 2 years) of supervised plumbing experience to qualify for a tradesman license—the first official step. Most aspiring plumbers fulfill this through an apprenticeship.
Your Apprenticeship Options:
| Union Apprenticeship(e.g., UA Local 68) | 4–5 years | Paid training, classroom instruction, job placement | Competitive entry, union dues |
| Non-Union Apprenticeship(with licensed contractor) | 2+ years | Flexible start, hands-on focus | Less structured curriculum |
| Trade School + On-the-Job Training | 1–2 years | Faster theory foundation | May cost tuition ($3K–$15K) |
⚠️ Important: Your supervising plumber must be licensed in Texas and report your hours to the state. Keep detailed logs—lost paperwork = delayed licensing.

Step 3: Apply for a Tradesman Plumber License
After 4,000 hours, you’re eligible for the Tradesman Plumber-Limited (TPL) license. This allows you to work under supervision on residential projects up to 2 stories.
Application Checklist:
✅ Proof of 4,000 supervised hours
✅ $33 application fee
✅ $78 exam fee
✅ Government-issued ID
Submit everything through the Texas State Board of Plumbing Examiners (TSBPE) portal: www.tsbpe.texas.gov
Step 4: Pass the Texas Plumbing Exam
The TPL exam has two parts:
- Law & Rules (25 questions) – Covers Texas plumbing code, ethics, and regulations
- Technical Knowledge (60 questions) – Tests pipe sizing, drainage, venting, and safety
You need 70% to pass. The test is open-book (you can bring codebooks), but time is tight—2.5 hours total.
📚 Study Resources:
- International Plumbing Code (IPC)
- Texas Administrative Code, Title 16, Chapter 70
- TSBPE’s free study guide (download on their website)
First-time pass rates hover around 65%—so don’t wing it. Most successful candidates spend 4–8 weeks prepping.
Step 5: Advance to Journeyman & Master Licenses
Once licensed, you can climb the ladder:
Journeyman Plumber License
- Requires 8,000 hours (4 years) of experience
- Allows independent work on all residential and light commercial projects
- Exam: $103 fee, 100 technical questions
Master Plumber License
- Requires 12,000 hours (6 years) + Journeyman license held for 1+ year
- Permits unlimited plumbing work, including design and supervision
- Qualifies you to start your own plumbing business
💼 Real-World Insight: “I went from apprentice to master in 6 years,” says Marcus R., a Houston-based plumbing contractor. “The license let me double my income and hire my own team.”
Common Mistakes to Avoid
- Skipping the background check: Even minor offenses can delay approval. Disclose everything upfront.
- Using unlicensed mentors: Hours only count if your supervisor holds a current Texas license.
- Ignoring continuing education: While Texas doesn’t require CE for renewal, staying updated on code changes prevents costly errors.
- Rushing the exam: Take a prep course—many community colleges (like Austin Community College) offer affordable options.
