Thinking about becoming a licensed plumber but unsure how long the process takes? You’re not alone. Many aspiring tradespeople wonder, “How long does it take to get a plumber license?”—especially when balancing work, family, or school. The good news: while timelines vary, most people can earn their license in 2 to 5 years, depending on their path and location. In this guide, we’ll break down every step clearly so you can plan your journey with confidence.
What Is a Plumber License and Why Do You Need One?
A plumber license is a legal credential issued by a state (or local) licensing board that authorizes you to perform plumbing work independently. Without it, you can’t legally pull permits, run your own business, or sign off on installations in most U.S. states.
According to the U.S. Bureau of Labor Statistics (BLS), employment of plumbers is projected to grow 5% from 2022 to 2032—faster than average—making this a stable and in-demand career. But to access those opportunities, licensing is non-negotiable.
How Long Does It Take to Get a Plumber License? (State-by-State Breakdown)
The time required depends heavily on your state’s regulations. Here’s a general overview:
State Type
Typical Timeline
Notes
Apprenticeship-First States (e.g., California, New York)
4–5 years
Must complete a registered apprenticeship before applying for a journeyman license.
Experience-Only States (e.g., Texas, Florida)
2–4 years
Accept documented work hours under a licensed plumber instead of formal apprenticeships.
Hybrid States (e.g., Illinois, Pennsylvania)
3–4 years
Combine classroom training with on-the-job experience.
Pass a background check (some states exclude felonies related to fraud or safety)
Step 2: Complete a Plumbing Apprenticeship or Training Program
Apprenticeships typically last 4–5 years and include:
2,000 hours of paid on-the-job training per year
144–200 hours of classroom instruction annually (covering blueprint reading, local codes, safety, etc.)
Alternatively, some states accept technical school diplomas (e.g., from a trade school) paired with fewer work hours.
According to the National Center for Construction Education and Research (NCCER), graduates of accredited programs often test better on licensing exams—boosting first-time pass rates by up to 25%.
Step 3: Gain Required Work Experience
After your apprenticeship (or training), you’ll usually apply for a Journeyman Plumber License. This requires:
2–4 years of documented experience under a licensed master plumber
Proof via W-2s, tax records, or employer affidavits
Note: In states like Alabama or Georgia, you can sit for the journeyman exam after just 1 year if you have a trade school certificate.
Step 4: Pass the Licensing Exam
Exams typically cover:
Local and national plumbing codes (based on the International Plumbing Code)
Math and blueprint interpretation
Safety and sanitation standards
Most exams are 100–150 multiple-choice questions with a 70–75% passing score. Study guides and prep courses are widely available—many candidates spend 4–8 weeks preparing.
📘 Expert Insight: “Candidates who take a formal exam prep course are twice as likely to pass on their first try,” says Maria Lopez, a licensing consultant with over 15 years in the trade education sector.
Step 5: Apply for Your License
Submit your application to your state board with:
Proof of experience
Exam results
Application fee ($50–$300, depending on the state)
Processing usually takes 2–6 weeks.
Step 6 (Optional): Upgrade to Master Plumber
After 2–5 more years as a journeyman, you can pursue a Master Plumber License, which allows you to:
Start your own plumbing business
Pull permits independently
Supervise apprentices
Factors That Affect Licensing Time
Several variables can speed up or delay your path:
Factor
Can Shorten Timeline?
Can Extend Timeline?
Prior trade experience
✅ (some states give credit)
❌
Full-time vs part-time apprenticeship
✅
❌ (part-time = longer)
Failed exam attempts
❌
✅ (retakes add weeks/months)
State processing delays
❌
✅ (common in CA, NY, IL)
Completing trade school
✅
❌
For example, if you attend a 2-year plumbing program at a community college, you might reduce on-the-job requirements by 6–12 months in states like Colorado or Oregon.
Real-World Example: John’s Journey in Texas
John, a 24-year-old from Austin, wanted to become a plumber after working in construction. Here’s his timeline:
Month 1–6: Enrolled in a 6-month plumbing certificate program at Austin Community College
Month 7–30: Worked 2.5 years under a licensed master plumber (documented 4,000+ hours)
Month 31: Passed the Texas Journeyman Plumber exam on first try
Month 32: Received his license
Total time: ~2 years 8 months—faster than the national average thanks to Texas’ flexible experience rules.
Common Mistakes That Delay Licensing
Avoid these pitfalls:
Not tracking work hours accurately → Leads to rejected applications
Ignoring local code differences → Plumbing codes vary by city (e.g., NYC vs. rural Montana)
Skipping exam prep → First-time pass rates drop to ~55% without study
Assuming reciprocity → Most states don’t accept out-of-state licenses without retesting
⚠️ For reference, plumbing regulations fall under state jurisdiction—there’s no national plumbing license in the U.S. (Source: Wikipedia – Plumbing).
FAQ Section
Q1: Can I get a plumber license without going to trade school?
Yes—in many states, you can substitute trade school with 4–5 years of documented apprenticeship experience under a licensed plumber. However, trade school can shorten the timeline and improve exam success.
Q2: How much does it cost to get a plumber license?
Total costs range from $1,000 to $5,000, including:
Apprenticeship (often paid, but some programs charge tuition)
Exam fees ($50–$200)
Application/license fees ($50–$300)
Study materials ($100–$300)
Q3: Do I need a license to do plumbing work at all?
In most states, yes—if you’re working for pay or on residential/commercial systems. Minor DIY home repairs are usually exempt, but anything involving permits or gas lines requires a license.
Q4: How long does the plumbing exam take?
Most state exams take 3–4 hours to complete. Some states split it into two parts: one on trade knowledge, another on business/law (for master licenses).
Q5: Can I get licensed in multiple states?
Yes, but you’ll likely need to retake exams and meet each state’s experience requirements. A few states (like those in the Midwest) have reciprocity agreements, but they’re limited.
Q6: What’s the difference between a journeyman and master plumber license?
A journeyman can work independently but can’t run a business or supervise apprentices. A master plumber can do all of that—and often needs 2–5 extra years of experience plus a more advanced exam.
Conclusion
So, how long does it take to get a plumber license? The answer is typically 2 to 5 years, but your exact timeline depends on your state, education path, and how quickly you accumulate experience. With strong demand, solid wages (median $60,000+ per year, per BLS), and opportunities for entrepreneurship, the investment pays off.
