Thinking about becoming a licensed plumber—but unsure how much it’ll really cost? You’re not alone. Many aspiring tradespeople ask, “How much does it cost to get a plumbing license?” The answer isn’t one-size-fits-all—it varies by state, experience level, and even your training path. But don’t worry: this guide breaks down every expense clearly, so you can plan your journey with confidence and no financial surprises.
What Is a Plumbing License—and Why Do You Need One?
Before diving into costs, let’s clarify what a plumbing license actually is. In most U.S. states, you must be licensed to legally perform plumbing work—especially on residential or commercial systems involving water, gas, or sewage.
A plumbing license proves you’ve met state-mandated standards for safety, code compliance, and technical skill. It protects consumers and boosts your credibility (and earning potential!). According to the U.S. Bureau of Labor Statistics, licensed plumbers earn a median annual wage of $60,090—and many top earners clear $90,000+ with experience.
💡 Fun fact: Plumbing is one of the oldest licensed trades in the U.S., with formal licensing dating back to the early 1900s as cities adopted modern sanitation systems [source: Wikipedia – Plumbing].

- Combines on-the-job training (2,000+ hours/year) with classroom instruction
💬 Pro Tip: The U.S. Department of Labor’s Apprenticeship.gov lists registered plumbing programs nationwide—many with no tuition fees.
3. Take Plumbing Classes (Optional but Recommended)
Cost: $1,000–$15,000
Trade schools (e.g., Lincoln Tech, Penn Foster) offer accelerated programs. While not always required, they boost exam pass rates.
4. Pass the Journeyman Plumbing Exam
Cost: $50–$300
Covers plumbing codes (typically IPC or UPC), math, blueprint reading, and safety.
- Most states use exams from PSI, Prov, or state-specific boards
- Pass rates average 65–75% on first attempt
5. Submit Your License Application
Cost: $75–$500
Includes:
- Proof of experience
- Exam score
- Background check ($25–$100)
- Fingerprinting (in some states)
6. Renew & Maintain Your License

Hidden Costs to Watch For
Don’t get blindsided! Beyond the obvious fees, consider:
- Study Materials: $50–$200 (code books, practice tests)
- Retake Fees: If you fail the exam, expect to pay again
- Bond or Insurance: Some states require a surety bond ($100–$500) or liability insurance

Plumbing License Costs vs. Potential Earnings: Is It Worth It?
Let’s do the math:
- Total upfront investment: ~$500–$2,000 (if you skip trade school)
- Average starting salary (licensed journeyman): $50,000–$65,000
- ROI timeline: <6 months for many
Compare that to unlicensed handymen who often earn $15–$25/hour—and can’t legally pull permits or work on major systems.
📊 According to HomeAdvisor, licensed plumbers charge $80–$150/hour, with emergency calls reaching $250/hour.
Verdict: Yes—it’s absolutely worth the investment.
