Thinking about becoming a plumber but unsure where to start? You’re not alone. Many aspiring tradespeople ask: “Do you need a license to be an apprentice plumber?” The short answer: usually not—but it depends on your state and employer. In this guide, we’ll clear up the confusion, break down real requirements, and show you exactly how to begin your plumbing journey the right way.
What Is a Plumbing Apprentice?
A plumbing apprentice is someone learning the trade under the supervision of a licensed journeyman or master plumber. Apprenticeships typically last 4 to 5 years and combine on-the-job training (around 2,000 hours per year) with classroom instruction (144+ hours annually).
According to the U.S. Bureau of Labor Statistics (BLS), employment of plumbers is projected to grow 5% from 2022 to 2032, faster than the average for all occupations—making now a great time to enter the field.
Do You Need a License to Be an Apprentice Plumber?
In most U.S. states, you do not need a plumbing license to start as an apprentice. However, you do need to be registered or enrolled in a state-approved apprenticeship program.
Here’s how it works:
Licensing applies to journeymen and master plumbers, not apprentices.
Apprentices must work under direct supervision of a licensed plumber.
Some states require apprentice registration (not a license) with a state board or agency.
For example:
California: Requires apprentice registration with the Department of Industrial Relations.
Texas: No state license for apprentices, but local jurisdictions may have rules.
New York: Mandates enrollment in a registered apprenticeship program.
⚠️ Warning: Working without proper registration (where required) can result in fines for both you and your employer.

Common Misconceptions About Apprentice Licensing
Let’s bust some myths:
❌ Myth: “I need a license before I can touch a pipe.” ✅ Truth: Apprentices learn by doing—but only under supervision.
❌ Myth: “All states have the same rules.” ✅ Truth: Rules vary widely. In Alabama, no registration is needed; in Oregon, you must register within 30 days of starting.
❌ Myth: “I can skip the classroom part.” ✅ Truth: Most states require 144+ hours of technical instruction per year to qualify for journeyman exams later.
Benefits of Starting as a Licensed Apprentice (Even Without a License)
While you don’t need a license, being a registered apprentice offers real advantages:
✅ Earn while you learn – Average apprentice pay: $18–$25/hour (BLS, 2024) ✅ Path to licensure – Completing an approved program fast-tracks your journeyman exam ✅ Job security – 94% of apprentices retain employment after completion (DOL data) ✅ No student debt – Unlike college, most programs cost little or nothing
FAQ: Do You Need a License to Be an Apprentice Plumber?
Q1: Can I work as a plumber without any license if I’m just helping a friend?
A: Technically, yes—but only if you’re not being paid and not doing work that requires a permit (like installing water heaters or sewer lines). Once you’re paid or doing regulated work, you must be a registered apprentice working under a licensed plumber.
Q2: How long does it take to go from apprentice to licensed plumber?
A: Typically 4–5 years. After completing your apprenticeship hours and classroom training, you can sit for the journeyman plumber exam in your state.
Q3: Do I need a high school diploma to become an apprentice?
A: Yes, nearly all programs require a high school diploma or GED. Strong math and reading skills are essential for reading blueprints and calculating pipe angles.
Q4: Can I start an apprenticeship at age 30 or older?
A: Absolutely! Plumbing welcomes career changers. The average apprentice age is 24, but many start in their 30s, 40s, or beyond.
Q5: What’s the difference between an apprentice, journeyman, and master plumber?
A:
Apprentice: In training, supervised, no license
Journeyman: Licensed to work independently (after 4–5 years + exam)
Master: Advanced license allowing you to run a business, pull permits, and supervise others
Q6: Are online plumbing courses enough to become an apprentice?
A: No. While online courses can help with theory, hands-on training under a licensed plumber is mandatory. State boards won’t accept purely online programs for licensure.
