How Long Does It Take to Get a Plumbing License? (2024 Guide)

Thinking about becoming a licensed plumber but unsure how long the process takes? You’re not alone. Many aspiring tradespeople ask, “How long does it take to get a plumbing license?”—and the answer isn’t one-size-fits-all. From apprenticeships to exams, the timeline depends on your state, experience, and dedication. In this guide, we’ll break down exactly what to expect so you can plan your path with confidence.

Why Does Plumbing License Timing Vary by State?

The U.S. doesn’t have a national plumbing license. Instead, each state (and sometimes counties or cities) sets its own rules. That means the time it takes to become licensed in California could differ drastically from Texas or New York.

According to the U.S. Bureau of Labor Statistics (BLS), most states require 2 to 5 years of hands-on experience before you can even sit for the licensing exam. Some states, like Pennsylvania, don’t require state-level licensing at all—though local jurisdictions often do.

💡 Pro Tip: Always check with your state’s plumbing board or department of labor first. The U.S. Department of Labor’s Apprenticeship Finder is a trusted starting point.

Step-by-Step Timeline: From Beginner to Licensed Plumber

Here’s a realistic, step-by-step breakdown of the typical journey:

1. Meet Basic Eligibility Requirements (Time: Immediate – 1 month)

Most states require:

• A high school diploma or GED
• Minimum age (usually 18)
• Clean background check (some states disqualify felony convictions)

2. Enroll in a Plumbing Apprenticeship (Time: 4–5 years)

This is the core phase. Apprenticeships combine on-the-job training (typically 8,000–10,000 hours) with classroom instruction (500–1,000 hours).

• Union programs (e.g., through UA – United Association) often last 5 years.
• Non-union or private apprenticeships may be shorter—some as fast as 3–4 years if you work full-time and complete coursework efficiently.

📊 Data Point: The BLS reports that 94% of plumbers learn via apprenticeships, making this the most common—and respected—path.

3. Apply for Your Journeyman License (Time: 1–3 months after apprenticeship)

Once you’ve logged the required hours, you can apply to take the journeyman plumber exam. Processing times vary:

• Fast states: Arizona, Florida (2–4 weeks)
• Slower states: California, New York (6–12 weeks)

The exam usually covers:

• Plumbing codes (IPC or UPC)
• Math and blueprint reading
• Safety and local regulations

Pass rates average 65–75% on the first try, according to industry surveys.

4. Work as a Journeyman (Optional but Recommended) (Time: 1–4 years)

Many plumbers stop at journeyman status. But if you want to own your own business or pull permits independently, you’ll need a master plumber license—which requires additional experience (usually 1–4 more years).

5. Take the Master Plumber Exam (Time: 1–2 months to schedule & pass)

This advanced test dives deeper into system design, code interpretation, and business practices.

State-by-State Comparison: How Long Does It Really Take?

⚠️ Note: Some states (e.g., Kansas, Missouri) allow reciprocity, meaning if you’re licensed in one state, you may qualify faster in another.

For a full list of licensing authorities, refer to the Wikipedia page on plumbing regulation in the United States , which provides helpful context on code adoption and oversight.

Can You Speed Up the Process?

Yes—with smart planning:

• Start early: Enroll in a pre-apprenticeship program at a trade school (e.g., Penn Foster, Lincoln Tech). These can count toward classroom hours.
• Work full-time: Part-time apprenticeships stretch the timeline.
• Study ahead: Use resources like PSI Exams or ICC study guides to prep early for the test.
• Track hours meticulously: Lost paperwork = delayed applications.

🛠️ Real Example: Marcus T., a plumber in Denver, completed his 3-year apprenticeship in 2.5 years by working 50+ hours/week and attending night classes. He passed his journeyman exam on the first try.

Common Mistakes That Delay Licensing

Avoid these pitfalls:

• Not verifying local requirements (city vs. state rules differ!)
• Missing continuing education (some states require it before renewal)
• Failing to renew on time (lapsed licenses mean restarting the clock)
• Skipping background checks (required in 40+ states)
