Thinking about becoming a licensed plumber—but unsure how much it’ll really cost? You’re not alone. Many aspiring tradespeople wonder, “How much does it cost to get a plumber’s license?” The answer isn’t one-size-fits-all—it varies by state, experience level, and the type of license you pursue. But don’t worry: this guide breaks down every expense clearly, so you can plan your career path with confidence and avoid surprise fees.
What Exactly Is a Plumber’s License?
A plumber’s license is an official credential issued by a state or local authority that allows you to legally perform plumbing work. Licensing ensures plumbers meet safety standards, understand local codes, and protect public health. In most U.S. states, working without a license—especially on residential or commercial projects—is illegal and can result in fines or legal action.
According to the U.S. Bureau of Labor Statistics (BLS), employment of plumbers is projected to grow 5% from 2024 to 2034, faster than average, driven by new construction and aging infrastructure. That makes now a smart time to enter the field—if you’re prepared for the investment.
How Much Does It Cost to Get a Plumber’s License? (By State)
Licensing costs vary significantly depending on where you live. Below is a comparison of total estimated costs for a journeyman plumber license—the most common entry-level credential—in several states:
| State | Application Fee | Exam Fee | Training/Education | Total Estimated Cost |
|---|---|---|---|---|
| Texas | $115 | $78 | $1,500–$3,000 | $1,700–$3,200 |

💡 Note: These totals include mandatory classroom or apprenticeship training, exam fees, background checks, and application processing. Some states (like Pennsylvania) require additional insurance or bonding, which can add $100–$500.

Step-by-Step: How to Get Your Plumber’s License (With Real Costs)
Here’s a realistic roadmap most states follow—with actual numbers based on 2026 data:
1. Complete a Plumbing Apprenticeship (2–5 Years)
Most states require 4,000–8,000 hours of hands-on training under a licensed plumber.
- Cost: Often $0 if you’re paid while learning (average apprentice wage: $18–$25/hour).
- However, some union programs charge $500–$2,000/year for classroom instruction.
2. Take Required Plumbing Courses
Even in paid apprenticeships, you’ll need classroom hours in:
- Blueprint reading
- Local plumbing codes (IPC or UPC)
- Safety protocols
- Typical cost: $1,200–$4,000 total over 2–4 years.
3. Apply for Your License
Submit proof of experience, pay fees, and undergo a background check.
- Application fee: $50–$150
- Background check: $25–$75
4. Pass the Licensing Exam
Exams cover code knowledge, math, and practical scenarios.
- Exam fee: $75–$150
- Study materials: $50–$200 (books, online courses, practice tests)
📌 Pro Tip: In states like Arizona and Colorado, you can take the exam before completing all hours—but you won’t receive the license until requirements are met.
5. Renew and Maintain Your License
Most licenses renew every 1–2 years.
- Renewal fee: $50–$200
- Continuing education: Often 4–8 hours/year at $20–$50/hour
Hidden Costs to Watch Out For
Don’t forget these often-overlooked expenses:
- Tools & Equipment: Basic toolkit = $500–$1,500
- Liability Insurance: Required in many states = $300–$800/year
- Business License: If you plan to work independently = $50–$300
- Travel & Time: Missed wages during exams or classes
While not part of the “license fee” itself, these impact your total startup cost.
Journeyman vs. Master Plumber: Which Should You Get?
| Credential | Experience Required | Avg. Cost | Salary Potential (2026) |
|---|---|---|---|
| Journeyman | 2–4 years | $1,500–$4,000 | $55,000–$75,000 |
| Master Plumber | 4–8 years + exam | $2,000–$5,500 | $80,000–$110,000+ |
Most professionals start as journeymen. A master license lets you pull permits, run a business, and supervise others—but it’s not required for entry-level work.
