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 and state requirements, the journey can take anywhere from 2 to 5+ years, depending on where you live and your prior experience. In this guide, we’ll break it down step by step so you can plan your path with confidence.
What Is a Plumbing License—and Why Do You Need One?
Before diving into timelines, it’s important to understand what a plumbing license actually is. In the U.S., a plumbing license is a state-issued credential that legally allows you to perform plumbing work for pay. Without it, you risk fines, legal trouble, or being barred from working on residential or commercial projects.
According to the U.S. Bureau of Labor Statistics, employment of plumbers is projected to grow 5% from 2022 to 2032—faster than average—making now a great time to enter the field. But you can’t skip the licensing process.
💡 Did you know? Some states (like Kansas and Missouri) don’t require a statewide plumbing license, but most cities and counties do. Always check local regulations.

How Long Does It Take to Get a Plumbing License? The Short Answer
On average, it takes 4 to 5 years to become a fully licensed journeyman plumber in most states. This includes:
- 2–5 years of apprenticeship (hands-on training + classroom instruction)
- Passing a state or local licensing exam
- Meeting age and education requirements (usually 18+ with a high school diploma or GED)
However, timelines vary significantly by state. Let’s look closer.
State-by-State Breakdown: Licensing Timelines Compared
| California | 4 years | Yes | 4–5 years |
| Texas | 4 years | Yes (for journeyman) | 4+ years |
| New York | 5 years | Yes | 5+ years |
| Florida | 4 years | Yes | 4–5 years |
| Illinois | 4–5 years | Yes | 4–6 years |
| Colorado | 4 years | Yes | 4–5 years |
⚠️ Note: Some states like Wyoming and South Dakota have minimal or no state-level plumbing licensing—but local jurisdictions often fill the gap.
Step-by-Step: How to Get Your Plumbing License (Timeline Included)
Step 1: Meet Basic Eligibility Requirements (Time: 0–1 month)
- Be at least 18 years old
- Have a high school diploma or GED
- Pass a background check (in most states)
Step 2: Enroll in a Plumbing Apprenticeship (Time: 2–5 years)
This is the longest phase. Most apprenticeships combine:
- 2,000+ hours of on-the-job training per year
- 144+ hours of classroom instruction annually
You’ll work under a licensed master plumber while learning pipefitting, blueprint reading, local codes, and safety protocols.
🛠️ Pro Tip: Join a union (like UA – United Association) or non-union program through a trade school. Union programs often pay you while you learn!
Step 3: Apply for Your Journeyman License (Time: 1–3 months)
Once you’ve completed your apprenticeship:
- Submit proof of hours (signed by your supervisor)
- Pay application fees ($50–$300, depending on state)
- Schedule your exam
Step 4: Pass the Licensing Exam (Time: 1 day + prep)
The exam typically covers:
- Plumbing codes (often based on the IPC – International Plumbing Code)
- Math calculations (pipe sizing, water pressure)
- Local regulations
Study guides and practice tests are available through your state’s licensing board.
Step 5: Receive Your License & Start Working (Time: 2–6 weeks)
After passing, your license is issued. You can now work independently as a journeyman plumber.
📈 Career Boost: After 2–5 more years as a journeyman, you can pursue a Master Plumber License, allowing you to run your own business.
Factors That Affect How Long It Takes
Several variables can speed up or delay your timeline:
✅ Prior Experience: Military veterans or those with related construction experience may get credit for some hours.
✅ Accelerated Programs: Some trade schools offer fast-track apprenticeships (e.g., 3-year programs in Arizona).
❌ Exam Failures: Failing the test adds weeks or months of re-study and re-testing.
❌ Incomplete Paperwork: Missing documentation is a common delay—keep meticulous records of your hours.
Common Mistakes That Delay Licensing (And How to Avoid Them)
- Not tracking work hours properly → Use a digital log or official apprentice timesheet.
- Ignoring local vs. state rules → A city license ≠ state license. Verify both.
- Skipping prep courses → Invest in a $50–$100 exam prep course—it boosts pass rates by 30%+.
- Assuming reciprocity → Most states don’t accept out-of-state licenses without retesting.
