Thinking about a career in plumbing but unsure how long it’ll take to get officially licensed? You’re not alone. Many aspiring tradespeople ask, “How long does it take to get a plumber license?” — and the answer isn’t one-size-fits-all. It depends on your state, experience, and how quickly you complete training and exams. But don’t worry: this guide breaks it all down clearly, so you can plan your path with confidence.
Why Licensing Matters for Plumbers in the U.S.
Before diving into timelines, it’s important to understand why licensing is non-negotiable. In nearly every U.S. state, you cannot legally perform plumbing work for pay without a license. Licensing protects public health and safety by ensuring plumbers understand local codes, water systems, and safety protocols. 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 now an excellent time to enter the field.
How Long Does It Take to Get a Plumber License? (State Breakdown)
The short answer: 2 to 5 years. But let’s unpack that.
Most states require a combination of apprenticeship hours, classroom instruction, and licensing exams. Here’s a general timeline:
| Step | Typical Duration | Details |
|---|---|---|
| 1. High School Diploma or GED | 0–4 years (already completed) | Required to start any formal plumbing path |
| 2. Plumbing Apprenticeship | 4–5 years | 8,000–10,000 hours of on-the-job training + 500–1,000 classroom hours |
| 3. Journeyman License Exam | 1–3 months prep | After apprenticeship; allows independent work under supervision |
| 4. Master Plumber License (optional) | Additional 1–2 years | Requires 1–4 more years of experience post-journeyman |
💡 Note: Some states (like Florida or Texas) allow you to sit for a journeyman exam after just 4 years, while others (like New York) may require 5 full years of verified experience.

Step-by-Step: How to Get Your Plumber License in the U.S.
Step 1: Meet Basic Eligibility Requirements
- Be at least 18 years old
- Have a high school diploma or GED
- Be legally authorized to work in the U.S.
Step 2: Enroll in a Plumbing Apprenticeship
Most future plumbers join a registered apprenticeship program through:
- A union (e.g., UA Plumbers & Pipefitters)
- A trade school (e.g., Lincoln Tech, Penn Foster)
- A private plumbing company that sponsors apprentices
⏱️ Typical commitment: 4–5 years, working 40+ hours/week on job sites while attending night classes 1–2 nights/week.
Step 3: Track and Verify Your Hours
Keep detailed logs of your work hours. Many states require notarized affidavits from licensed plumbers who supervised you. Missing paperwork can delay your application by months.
Step 4: Apply for Your Journeyman License
Submission requirements often include:
- Completed application form
- Proof of hours (usually 4,000–8,000 depending on state)
- Application fee ($50–$300)
- Background check
Step 5: Pass the Licensing Exam
The exam usually covers:
- Local and national plumbing codes (IPC or UPC)
- Math for pipe sizing and pressure calculations
- Safety and backflow prevention
📊 Pass rates: Vary by state, but average around 65–75% on the first try. Studying with official prep materials (like those from PSI or Prometric) boosts success.
Step 6: Receive Your License & Renew as Required
Most licenses must be renewed every 1–2 years, often with continuing education credits (4–8 hours annually).
State-by-State Timeline Comparison
| State | Min. Apprenticeship | Journeyman Exam Eligibility | Total Time (Approx.) |
|---|---|---|---|
| Texas | 4 years | After 4 years | 4–4.5 years |
| California | 4 years | After 4 years + 720 class hours | 4–5 years |
| New York | 5 years | After 5 years | 5+ years |
| Florida | 4 years | After 4 years + 600 class hours | 4–4.5 years |
| Illinois | 4 years | After 4 years | 4–5 years |
⚠️ Important: Always check your state’s plumbing board website (e.g., CSLB for California, TDLR for Texas). Rules change frequently!
Common Reasons for Delays (And How to Avoid Them)
Even with good planning, setbacks happen. Here’s how to stay on track:
- Incomplete documentation: Use a digital log app (like ClockShark or Fieldwire) to track hours in real time.
- Failing the exam: Take a prep course. Many trade schools offer free retake support.
- Background issues: Disclose any past convictions early—some states offer waivers.
- Moving between states: Licenses don’t transfer. You may need to re-test or complete additional hours.
FAQ: How Long Does It Take to Get a Plumber License?
Q1: Can I get a plumber license without an apprenticeship?
In most states, no. A few (like Montana or Alaska) allow “experience-only” paths if you’ve worked under a licensed plumber for years—but you still need verifiable proof and must pass the same exam.
Q2: How much does it cost to get licensed?
Total costs range from $1,000 to $4,000, including:
- Apprenticeship tuition (if attending trade school): $500–$2,000/year
- Exam fees: $50–$200
- License application: $100–$300
- Study materials: $50–$200
Q3: Can I work while getting my license?
Yes! As an apprentice, you earn while you learn—average starting wage is $18–$25/hour, with raises each year.
Q4: What’s the difference between a journeyman and master plumber license?
A journeyman can install and repair systems but can’t pull permits or run a business. A master plumber can do all that, supervise others, and often earns 20–30% more.
Q5: Do I need a license for small jobs like fixing a leaky faucet?
If you’re charging for the work, yes—even for minor repairs. Unlicensed plumbing can result in fines up to $5,000 in states like California.
Q6: How fast can I get licensed if I already have construction experience?
Some states offer credit for related experience (e.g., pipefitting or HVAC), potentially reducing required hours by 10–20%. But you’ll still need plumbing-specific training and must pass the plumbing code exam.
Conclusion: Your Plumbing License Is Worth the Wait
So, how long does it take to get a plumber license? Typically 4 to 5 years—but that investment pays off fast. Licensed plumbers in the U.S. earn a median salary of $60,000/year, with top earners clearing $100,000+, especially in high-demand areas like California or the Northeast.
More importantly, you’ll join a recession-resistant trade where your skills are always in demand. Whether you’re drawn to the hands-on work, problem-solving, or independence of the job, licensing is your golden ticket.
