How Do I Get My Journeyman Plumbing License? (Step-by-Step Guide)

Dreaming of turning your plumbing skills into a certified, respected career? You’re not alone. Thousands of apprentices and trade school grads ask, “How do I get my journeyman plumbing license?” every year—and for good reason. This license is your ticket to higher pay, greater job flexibility, and professional credibility. In this guide, we’ll walk you through every step clearly, accurately, and without the confusing jargon.

What Is a Journeyman Plumbing License?

A journeyman plumbing license certifies that you’ve completed the required training, hands-on experience, and passed an exam to legally perform plumbing work independently—though usually still under the supervision of a master plumber, depending on your state.

Unlike an apprentice (who works under direct supervision), a journeyman can install, repair, and inspect plumbing systems solo in most jurisdictions. According to the U.S. Bureau of Labor Statistics, licensed plumbers earn a median annual wage of $60,090—and journeymen often command 20–30% more than unlicensed technicians.

Step-by-Step: How to Get Your Journeyman Plumbing License

While requirements vary by state, the core process is similar across the U.S. Follow these 5 essential steps:

1. Complete a Plumbing Apprenticeship (Typically 4–5 Years)

Most states require 4 to 5 years (or 6,000–8,000 hours) of documented, supervised plumbing experience. This is usually fulfilled through a formal apprenticeship program that combines:

• On-the-job training (85–90% of time)
• Classroom instruction (10–15%, covering codes, safety, blueprint reading, etc.)

You can find registered apprenticeships through:

• Local plumbers’ unions (e.g., UA – United Association)
• Trade schools (e.g., Lincoln Tech, Penn Foster)
• State workforce development boards

✅ Pro Tip: Keep detailed logs of your work hours. Some states require signed affidavits from your supervising plumber.

2. Meet Your State’s Eligibility Requirements

Each state sets its own rules. Common requirements include:

👉 Check your state’s plumbing board website. For example:

• California: CSLB
• Texas: TSBPE
• New York: NYSDOL

3. Submit Your License Application

Once you meet eligibility, apply through your state plumbing licensing board. You’ll typically need:

• Completed application form
• Proof of experience (signed by employer/master plumber)
• Official transcripts (if from a trade school)
• Application fee ($50–$300, depending on state)

Processing can take 2–8 weeks, so apply early.

4. Prepare for and Pass the Journeyman Plumbing Exam

The exam tests your knowledge of:

• Plumbing codes (usually based on the IPC – International Plumbing Code or UPC – Uniform Plumbing Code)
• Local amendments (state-specific rules)
• Math, blueprint reading, and safety practices

Exam Format:

• 80–120 multiple-choice questions
• 3–4 hours allotted
• Passing score: Usually 70–75%

📚 Study Resources:

• International Plumbing Code (IPC) – latest edition
• PSI or ICC exam prep books
• Online practice tests (e.g., Plumbers Training Institute, RedVector)

📊 Pass Rate Insight:
According to industry data, first-time pass rates average 65–75%. Those who use structured study plans are 2x more likely to pass on the first try.

5. Receive Your License and Maintain It

After passing, you’ll receive your journeyman plumbing license—often valid for 1–3 years. Most states require continuing education (CE) for renewal (e.g., 4–8 hours every 2 years on code updates or safety).

State-by-State Variations: What You Must Know

Not all licenses are equal. For example:

• Florida: No statewide journeyman license—licensing is handled at the county level.
• Illinois: Requires 4 years of experience + 300 hours of classroom training.
• Oregon: Mandates a separate backflow prevention certification.
• New Jersey: Requires both written and practical exams.

🔍 Always verify with your local authority. A license in one state rarely transfers automatically.

Common Mistakes to Avoid

• Assuming all states have the same rules → They don’t. Research yours.
• Underestimating the code exam → It’s not just “common sense”—it’s technical.
• Missing renewal deadlines → Letting your license lapse means reapplying (and possibly retesting).
• Failing to document experience properly → Unsigned or vague work logs get rejected.

Journeyman vs. Master Plumber: What’s the Difference?

Many journeymen use this license as a stepping stone to master status—which opens doors to entrepreneurship and higher earnings.

FAQ: Frequently Asked Questions

Q1: How long does it take to get a journeyman plumbing license?

A: Typically 4–6 years total—4–5 years as an apprentice + a few months to apply, study, and test. Some accelerated programs may shorten this slightly, but hands-on experience is non-negotiable in most states.

Q2: Can I get a journeyman license without an apprenticeship?

A: In very few states (e.g., some allow trade school credits to substitute part of the hours), but almost all require documented field experience. Self-taught plumbers usually can’t qualify.

Q3: How much does it cost to get licensed?

A: Total costs range from $300 to $1,000, including:

• Application fees ($50–$300)
• Exam fees ($100–$250)
• Study materials ($50–$200)
• Background check ($25–$75)

Q4: Do I need a journeyman license to work as a plumber?

A: Yes, in most states. Working without a license can result in fines, job loss, or even legal action—especially if you’re doing work beyond basic repairs.

Q5: Can I work in another state with my license?

A: Not automatically. Some states have reciprocity agreements (e.g., between Texas and Louisiana), but you’ll usually need to pass that state’s code exam or meet additional requirements.

Q6: What if I fail the exam?

A: Most states allow you to retake it after 30–90 days. You’ll pay a retest fee (usually $75–$150). Use the time to review weak areas—many who fail the first time pass on the second attempt.

Final Thoughts: Your License, Your Future

Earning your journeyman plumbing license isn’t just about checking a box—it’s about professional pride, financial growth, and career control. With the U.S. facing a shortage of skilled tradespeople, licensed plumbers are in high demand across residential, commercial, and industrial sectors.

If you’ve put in the hours and honed your craft, the license is your well-earned reward. Follow the steps, study smart, and trust the process.
