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

Thinking about a stable, hands-on career with strong earning potential? You’re not alone—plumbing is one of America’s most in-demand skilled trades, with over 500,000 jobs projected by 2032 (U.S. Bureau of Labor Statistics). But before you can fix a leak or install a water heater, you need to know how do you get a plumbing apprentice license—the essential first step toward becoming a licensed plumber. This guide breaks it all down clearly, so you can start your journey with confidence.

What Is a Plumbing Apprentice License?

A plumbing apprentice license (often called an apprentice registration) is your official entry ticket into the plumbing trade. It’s not a full license to work independently—instead, it allows you to train under a licensed master plumber while earning a wage and completing classroom instruction. Most states require this registration before you can legally begin on-the-job training.

💡 Did You Know?
According to the U.S. Department of Labor, plumbing apprentices typically earn 40–50% of a journeyman’s wage in their first year—with regular raises as they gain skills.

Do All States Require a Plumbing Apprentice License?

No—requirements vary by state. While most states regulate plumbing at the state or local level, a few (like Kansas and Wyoming) have minimal or no state-wide plumbing licensing. However, even in unregulated states, cities or counties often require apprentice registration.

To check your state’s rules, visit your state’s plumbing board website or the U.S. Department of Labor’s Apprenticeship Finder (an official .gov resource).

✅ Pro Tip: Always verify local requirements—even if your state doesn’t mandate it, your city might.

Step-by-Step: How Do You Get a Plumbing Apprentice License?

Here’s the exact process most aspiring plumbers follow:

1. Meet Basic Eligibility Requirements

Most states require you to:

• Be at least 16–18 years old (18 in most states)
• Have a high school diploma or GED
• Be legally authorized to work in the U.S.
• Pass a drug screening (common for union programs)

2. Find a Sponsoring Employer or Program

You can’t apply alone—you need a licensed plumbing contractor or union to sponsor your apprenticeship. Options include:

• Union programs (e.g., UA Plumbers and Pipefitters)
• Non-union contractor-sponsored programs
• State-registered apprenticeship programs

🔍 How to Find One:
Use the U.S. Department of Labor’s Apprenticeship Job Finder to search for registered plumbing apprenticeships near you.

3. Submit Your Application to the State or Local Board

Once you have a sponsor, apply for apprentice registration. This usually involves:

• Completing an application form
• Paying a fee ($25–$100, depending on location)
• Providing proof of employment/sponsorship
• Submitting ID and education documents

Processing times range from 1–4 weeks.

4. Begin Your Apprenticeship (On-the-Job + Classroom Training)

A standard plumbing apprenticeship lasts 4–5 years and includes:

• 2,000 hours of paid on-the-job training per year
• 144–200 hours of classroom instruction annually (covering safety, blueprint reading, local codes, etc.)

📚 Example: In California, apprentices attend classes at a trade school or union hall one night per week while working full-time with a licensed plumber.

5. Track Your Hours and Pass Required Exams

Keep detailed logs of your work hours. Many states require periodic progress reviews and may ask you to pass interim exams before advancing.

After completing your apprenticeship, you’ll be eligible to take the journeyman plumber exam—the next step in your career.
