How To Get Your Plumbing License From State to State

Thinking about moving your plumbing business—or your career—to another state? You’re not alone. Thousands of licensed plumbers relocate each year, only to discover that how to get your plumbing license from state to state isn’t as simple as packing a toolbox. Each state sets its own rules, experience thresholds, and exam standards. But don’t worry—you’re in the right place. This guide breaks down exactly what you need to know to transfer or obtain a new plumbing license legally, efficiently, and without costly delays.

Why Plumbing Licenses Vary by State

Plumbing isn’t just about fixing leaks—it’s about public health, safety, and compliance with local building codes. That’s why the U.S. doesn’t have a national plumbing license. Instead, each state (and sometimes individual counties or cities) regulates its own licensing process through a state board or department of professional regulation.

According to the U.S. Bureau of Labor Statistics, there were over 520,000 plumbers, pipefitters, and steamfitters employed nationwide in 2024, with job growth projected at 5% through 2034. Yet, less than half of states offer full or partial license reciprocity—meaning you often can’t just “transfer” your credentials.

💡 “State-specific plumbing codes reflect regional needs—from freeze-proof piping in Minnesota to seismic bracing in California,” explains Maria Lopez, a senior licensing consultant at the National Inspection Testing and Certification Corporation (NITC).

Step-by-Step: How to Get Your Plumbing License in a New State

1. Determine Your Target State’s Licensing Authority

Start by identifying the correct agency. Most states use a:

• State Board of Plumbers
• Department of Professional Regulation
• Division of Occupational Licensing

For example:

• Texas → Texas State Board of Plumbing Examiners
• Florida → Department of Business and Professional Regulation (DBPR)
• California → Contractors State License Board (CSLB)

🔍 Tip: Search “[State Name] plumbing license board” to find the official site.

2. Check License Type & Classification

States classify plumbing licenses differently:

• Apprentice (entry-level, supervised work)
• Journeyman (mid-level, can work independently)
• Master Plumber (can supervise, design systems, pull permits)

Some states (like Illinois) also require separate endorsements for gas fitting or medical gas.

3. Review Experience Requirements

Most states require 4–5 years of documented plumbing experience under a licensed plumber. However, this varies:

Keep detailed logs: dates, employer names, project types, and supervisor contact info.

4. Verify Reciprocity Agreements

Only a handful of states have formal reciprocity:

• Alabama ↔ Georgia ↔ Mississippi (via Southern States Agreement)
• North Dakota ↔ South Dakota ↔ Minnesota (limited reciprocity)

Even with reciprocity, you may still need to:

• Pass a state-specific code exam
• Pay application fees ($100–$500)
• Complete background checks

⚠️ No state offers automatic nationwide recognition. Always confirm current rules—policies change frequently.

5. Prepare for Exams (If Required)

Most states require passing:

• A trade exam (practical plumbing knowledge)
• A business/law exam (if applying for a contractor license)

Study materials are often available through:

• PSI Exams (administers tests in 30+ states)
• State board websites
• Prep courses from organizations like PHCC (Plumbing-Heating-Cooling Contractors Association)

Average pass rates hover around 65–75%, so thorough prep is essential.

6. Submit Your Application

Gather these common documents:

• Proof of identity (driver’s license, SSN)
• Work experience affidavits (signed by licensed supervisors)
• Transcripts (if using trade school hours)
• Exam scores
• Application fee

Processing times range from 2 weeks (Utah) to 12+ weeks (California).

7. Maintain Your Original License (If Possible)

Don’t let your home-state license expire during the transition. Some states require an active license from your previous state to qualify for reciprocity or reduced requirements.

Common Challenges & How to Avoid Them

❌ Assuming All Licenses Are Equal

A “journeyman” in one state may be equivalent to an “apprentice” in another. Always compare scope-of-work definitions.

❌ Missing Continuing Education (CE) Requirements

States like Florida and Massachusetts require CE credits to renew or transfer licenses. Track your hours early.

❌ Underestimating Local Code Differences

The International Plumbing Code (IPC) is adopted by most states—but with amendments. For instance:

• California requires water-conserving fixtures by law.
• Texas has strict backflow prevention rules.

Familiarize yourself with your new state’s adopted code version (e.g., IPC 2021 vs. 2024).

Pro Tips for a Smooth Transition

• ✅ Contact the state board directly—many offer pre-application consultations.
• ✅ Join a local union or trade association (e.g., UA – United Association) for support and networking.
• ✅ Use digital tools like License Finder (by NCCCO) or CareerOneStop (U.S. Dept. of Labor) to compare state requirements side-by-side.
• ✅ Keep all records digitized—PDFs of pay stubs, W-2s, and signed affidavits save time.

FAQ Section

Q1: Can I work as a plumber in another state while waiting for my license?

A: Generally, no. Most states prohibit unlicensed plumbing work—even minor repairs. Some allow temporary permits for emergency work, but these are rare and tightly regulated.

Q2: Do military veterans get expedited plumbing licensing?

A: Yes! Over 35 states participate in the Veterans Licensing Initiative, which waives fees, accepts military training as experience, and fast-tracks applications. Check your target state’s veteran services office.

Q3: What if my home state doesn’t license plumbers?

A: A few states (e.g., Kansas, Missouri, Wyoming) don’t require state-level plumbing licenses—only local city/county permits. In this case, you’ll likely need to start as an apprentice or prove equivalent experience through work history and exams.

Q4: How much does it cost to get licensed in a new state?

A: Total costs typically range from $300 to $1,200, including:

• Application fees ($100–$500)
• Exam fees ($75–$200)
• Background checks ($50)
• Study materials ($100–$300)

Q5: Can I hold plumbing licenses in multiple states?

A: Absolutely—and many contractors do. There’s no legal limit, though maintaining them requires tracking renewal dates, CE credits, and fees for each.

Q6: How long does the entire process take?

A: On average, 4 to 12 weeks—but it can stretch to 6 months in high-demand states like California or New York if documentation is incomplete.
