How Do You Get a Journeyman Plumbing License? (Step-by-Step Guide)

Thinking about leveling up your plumbing career? If you’ve been working as an apprentice and are now ready for more responsibility—and higher pay—you’re probably asking: how do you get a journeyman plumbing license? This license is a major milestone that proves your skills, boosts your credibility, and opens doors to better jobs and even self-employment. In this guide, we’ll walk you through every step, from training hours to state exams, so you can earn your license with confidence.

What Is a Journeyman Plumbing License?

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

Unlike an apprentice, a journeyman can:

• Install, repair, and maintain plumbing systems
• Read blueprints and building codes
• Diagnose and solve complex plumbing issues
• Pull permits in some jurisdictions

According to the U.S. Bureau of Labor Statistics (BLS), licensed plumbers earned a median annual wage of $60,090 in 2023, with journeyman-level plumbers often earning 15–25% more than apprentices.

💡 Pro Tip: While licensing is handled at the state or local level, the general path is similar nationwide—just with different hour requirements and exam formats.

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

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

Most states require 4 to 5 years (or 8,000–10,000 hours) of documented on-the-job training under a licensed master plumber or approved plumbing contractor.

• Apprenticeships often combine paid fieldwork with classroom instruction (usually 144+ hours per year).
• Many are offered through unions (like UA Local 136) or trade schools.
• Keep detailed logs of your work—states like Texas and California audit these records.

2. Meet Your State’s Eligibility Requirements

Requirements vary by state, but common criteria include:

• Minimum age (usually 18+)
• High school diploma or GED
• Proof of completed apprenticeship hours
• Clean criminal background (some states disqualify felony convictions related to fraud or violence)

📌 Example:

• New York: 7,000 hours of experience + 500 classroom hours
• Florida: 4 years (8,000 hours) under a certified contractor
• California: Varies by city—Los Angeles requires 8,000 hours + 2,000 school hours

3. Submit Your Application & Pay Fees

Once eligible:

• Apply through your state’s plumbing licensing board (or local jurisdiction).
• Submit proof of experience, school transcripts, and ID.
• Pay application fees ($50–$300, depending on location).

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

4. Prepare for and Pass the Journeyman Plumbing Exam

The exam tests:

• Trade knowledge (pipe sizing, venting, drainage, gas lines)
• Local and national plumbing codes (usually based on the IPC—International Plumbing Code)
• Math and blueprint reading

Most exams are multiple-choice, 80–100 questions, with a 70%+ passing score.

📚 Study Resources:

• International Plumbing Code (IPC) – latest edition
• Plumbing Exam Prep by Contractor Campus
• Practice tests from PSI Services or IBT

⏱️ Average Study Time: Successful candidates spend 40–80 hours preparing.

5. Receive Your License and Renew as Required

After passing:

• You’ll receive your journeyman plumbing license (physical card or digital certificate).
• Some states issue it immediately; others mail it in 2–4 weeks.
• Renewal is typically every 1–2 years, often requiring continuing education (e.g., 4–8 hours on code updates or safety).

State-by-State Comparison: Key Requirements at a Glance

📌 Note: Always verify with your state’s plumbing board—rules change frequently.

Common Mistakes to Avoid

• ❌ Under-reporting work hours: Keep a daily log signed by your supervisor.
• ❌ Ignoring local amendments: The IPC is national, but cities like Chicago or NYC have stricter local codes.
• ❌ Cramming last-minute: Plumbing codes are complex—start studying early.
• ❌ Assuming reciprocity: Most states do not accept out-of-state licenses without retesting.

Benefits of Holding a Journeyman License

• Higher Earnings: Journeymen earn $25–$40/hour vs. $15–$22 for apprentices.
• Job Security: Skilled trades face chronic labor shortages—BLS projects 5% job growth through 2032.
• Career Flexibility: Work for contractors, go union, or start your own business (after becoming a master).
• Professional Credibility: Clients and employers trust licensed professionals.

FAQ Section

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

A: Typically 4–5 years of apprenticeship plus exam prep. From application to license issuance, the final process takes 1–3 months.

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

A: In most states, no. Formal apprenticeship or equivalent documented experience is mandatory. A few states (like Arizona) allow “experience-only” paths, but these are rare and heavily scrutinized.

Q: Is the journeyman exam hard?

A: It’s challenging but passable with preparation. Nationally, first-time pass rates average 65–75%. Focus on code comprehension—not just memorization.

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

A: In licensed states (like CA, NY, TX), yes—you cannot legally perform plumbing work without a license at the appropriate level. In unlicensed states (like Kansas or Missouri), certification is optional but still valuable for credibility.

Q: Can I work in another state with my journeyman license?

A: Generally, no. Plumbing licenses are not reciprocal across state lines. You’ll likely need to reapply, possibly retake the exam, and meet local requirements.

Q: What’s the difference between journeyman and master plumber?

A: A journeyman works independently but can’t pull permits or run a business in most states. A master plumber has 2+ additional years of experience, passes a more advanced exam, and can supervise teams, own a company, and approve plans.
