Thinking about becoming a plumber—but unsure how long it’ll take to get licensed? You’re not alone. Many aspiring tradespeople ask, “How long does it take to get a plumber license?” The answer isn’t one-size-fits-all—it depends on your state, experience, and how quickly you move through training. But don’t worry: this guide breaks it all down so you can plan your path with confidence.
How Long Does It Take to Get a Plumber License? The Short Answer
On average, it takes 2 to 5 years to earn a full plumbing license in the U.S. This includes completing an apprenticeship (typically 4–5 years), passing exams, and meeting state-specific requirements. However, some states allow you to work as a plumbing apprentice or journeyman while training—meaning you can earn while you learn.
💡 Pro Tip: In states like Texas or Florida, you may qualify for a provisional license after just 1–2 years of supervised work—great for getting your foot in the door faster.
Why Licensing Timelines Vary by State
Plumbing is regulated at the state level, not federally. That means licensing rules, required hours, and exam formats differ widely. For example:
| California | 8,000 hours (4 years) | 4–5 years |
| New York | 7,000 hours | 3.5–4.5 years |
| Texas | 4,000–8,000 hours* | 2–5 years |
| Florida | 4,800 hours | 2.5–4 years |
* Texas offers tiered licensing (Apprentice → Journeyman → Master), so timelines vary by goal.
Always check your state’s plumbing board website for exact rules. The U.S. Bureau of Labor Statistics confirms that licensing is mandatory in all 50 states for independent work.
Step-by-Step: How to Get Your Plumber License
Follow these 5 key steps—most take 4–5 years total, but you’ll be working (and earning) throughout:
1. Meet Basic Eligibility Requirements
- Be at least 18 years old
- Have a high school diploma or GED
- Pass a background check (required in most states)
2. Enroll in a Plumbing Apprenticeship
This is the core of your training. Most apprenticeships:
- Last 4–5 years
- Require 1,500–2,000 hours of on-the-job training per year
- Include 144–200 hours of classroom instruction annually
You can find registered programs through:
- Unions (e.g., UA Plumbers & Pipefitters)
- Trade schools
- Local contractors
📌 Real Example: In Illinois, the Chicago JATC (Joint Apprenticeship Training Committee) runs a 5-year program with paid on-site work and weekly classes.
3. Track Your Work Hours Meticulously
Your state will require proof of supervised hours. Keep detailed logs signed by your supervising plumber. Missing documentation = delays.
4. Apply for a Journeyman License
After completing your apprenticeship:
- Submit your hours to the state licensing board
- Pay the application fee ($50–$300, depending on state)
- Schedule your journeyman exam
The exam usually covers:
- Plumbing codes (IPC or UPC)
- Math & blueprint reading
- Safety & installation practices
5. Pass the Exam & Get Licensed
Most states use exams from PSI or ICC. Study with official prep materials. First-time pass rates average 65–75%—so prep well!
Once licensed, you can work independently (in most states) or pursue a Master Plumber license after 1–2 more years.
Can You Speed Up the Process?
Yes—strategically. Here’s how:
✅ Start early: Some states (like Oregon) let you begin apprenticeship hours right after high school.
✅ Take night classes: Accelerate classroom requirements while working days.
✅ Choose high-demand areas: Rural states may fast-track applicants due to labor shortages.
✅ Use military experience: Veterans can often count service hours toward licensing (check VA programs).
However, don’t skip steps. Licensing ensures public safety—cutting corners risks fines or denial.
Common Mistakes That Delay Licensing
Avoid these pitfalls that add months (or years) to your timeline:
- ❌ Not verifying your trainer’s license (your hours won’t count if they’re unlicensed)
- ❌ Missing application deadlines (some states only accept apps quarterly)
- ❌ Underestimating exam prep (plumbing codes change yearly—use 2024 editions)
- ❌ Moving states mid-apprenticeship (you may lose credit for past hours)
⚠️ Expert Insight: “I’ve seen candidates wait 6 extra months because they used outdated study guides,” says Maria Lopez, a licensing examiner in Arizona with 12 years of experience.
Plumbing License vs. Certification: What’s the Difference?
Many confuse these terms—but they’re not the same:
| Mandatoryto work legally in most states | Voluntary(e.g., backflow prevention, medical gas) |
| Issued bystate government | Issued byprivate orgs(e.g., NCCER, PHCC) |
| Allowsindependent contracting | Showsspecialized skill—boosts resume |
While certification isn’t required, it increases earning potential by 10–15% (per PHCC data ).
