If you’re considering plumbing work in the Lone Star State—whether you’re a homeowner tackling a DIY project or a new tradesperson building a career—you’ve probably asked yourself: “Do you have to be a licensed plumber in Texas?” The short answer? It depends. But the consequences of getting it wrong can be serious, from fines to safety hazards. In this guide, we’ll break down exactly when a license is required, who’s exempt, and why it matters—for your wallet, your home, and your legal protection.
Is a Plumbing License Required in Texas?
Yes—in most cases, you must be a licensed plumber to legally perform plumbing work in Texas. The Texas State Board of Plumbing Examiners (TSBPE) oversees all plumbing licensing and enforcement. However, there are notable exceptions that often cause confusion.
According to the Texas Occupations Code, Chapter 1301 , anyone installing, repairing, or altering plumbing systems that connect to public water or sewer lines must hold a valid state license. This includes residential, commercial, and industrial plumbing.
💡 Key Fact: As of 2025, Texas reinstated full authority to the TSBPE after a temporary sunset in 2021. Licensing is now fully enforced statewide.
Who Can Legally Do Plumbing Work Without a License?
Not everyone needs a license—but the exemptions are narrow and strictly defined:
1. Homeowners Doing Work on Their Own Primary Residence
If you own and live in the home, you can perform plumbing work yourself without a license. However:
You cannot hire unlicensed help to assist you.
You must still comply with local building codes and obtain permits.
The work cannot be for resale (e.g., flipping houses).
2. Farm or Ranch Owners (for Agricultural Use Only)
Property owners can install or repair plumbing on land used exclusively for farming or ranching, as long as it’s not connected to a public water or sewer system.
3. Manufactured Home Installers (Limited Scope)
Installers certified by the Texas Department of Housing and Community Affairs (TDHCA) may connect plumbing in manufactured homes—but only as part of the initial setup, not for repairs or modifications later.
⚠️ Warning: Many contractors falsely claim “handyman exemptions.” Texas does not have a general handyman license that covers plumbing. If the job involves water supply, drainage, or gas lines, a plumbing license is almost always required.
What Happens If You Work Without a License?
Operating as an unlicensed plumber in Texas isn’t just risky—it’s illegal. Penalties include:
Fines up to $5,000 per violation
Cease-and-desist orders
Inability to collect payment (courts often side with homeowners in disputes with unlicensed workers)
Liability for damages if faulty work causes leaks, mold, or structural damage
A 2023 report from the TSBPE showed that over 1,200 enforcement actions were taken against unlicensed plumbing activity—up 18% from 2022. One Houston contractor was fined $28,000 after installing faulty gas lines in three homes, leading to a minor explosion.

Licensed vs. Unlicensed Plumbers: What’s the Real Difference?
Legal Authority
✅ Fully authorized by the state
❌ Operating illegally in most cases
Insurance & Bonding
✅ Usually carries liability insurance
❌ Rarely insured
Code Compliance
✅ Trained in current plumbing codes
❌ May cut corners or use outdated methods
Warranty
✅ Work often guaranteed
❌ No recourse if something goes wrong
Permit Handling
✅ Can pull permits legally
❌ Cannot obtain permits
Choosing a licensed professional isn’t just about legality—it’s about safety, reliability, and peace of mind.
Why Licensing Matters: Safety, Standards, and Trust
Plumbing isn’t just about fixing leaks. Poorly installed systems can lead to:
Backflow contamination (mixing sewage with drinking water)
Gas leaks from improper pipe fittings
Structural damage from hidden water intrusion
The Uniform Plumbing Code (UPC), adopted by Texas, exists to prevent these risks. Licensed plumbers are trained to follow these standards—unlicensed workers often aren’t.
According to a Wikipedia overview of plumbing codes , standardized regulations reduce public health risks by up to 60% in developed regions. In Texas, where droughts and hard water add extra strain on systems, proper installation is even more critical.
FAQ: Do You Have To Be a Licensed Plumber in Texas?
Q1: Can a handyman do plumbing in Texas?
A: Only if the work is minor (e.g., replacing a faucet washer) and doesn’t involve altering pipes, drains, or water supply lines. Any work beyond basic maintenance requires a plumbing license.
Q2: Do I need a license to replace a water heater?
A: Yes. Installing or replacing a water heater involves gas lines, electrical connections, or plumbing modifications—all of which require a licensed plumber in Texas.
Q3: Are cities in Texas allowed to set their own plumbing rules?
A: Local jurisdictions can enforce stricter codes, but they cannot waive the state licensing requirement. For example, Austin and Dallas both require additional permits, but the plumber must still be TSBPE-licensed.
Q4: How can I verify if a plumber is licensed?
A: Use the official TSBPE License Lookup Tool . Enter the plumber’s name or license number to confirm status and any disciplinary history.
Q5: What if I hired an unlicensed plumber by accident?
A: You may be able to file a complaint with TSBPE. However, you could also face issues with insurance claims or home inspections if unpermitted work is discovered.
Q6: Can I get a plumbing license with a criminal record?
A: It depends. The TSBPE reviews applications case-by-case. Minor offenses may not disqualify you, but felonies related to fraud, theft, or violence could.
Conclusion: When in Doubt, Go Licensed
So, do you have to be a licensed plumber in Texas? For almost all professional plumbing work—yes. While limited exemptions exist for homeowners and agricultural use, the vast majority of installations, repairs, and modifications require a state-issued license.
Choosing a licensed plumber protects your home, your health, and your legal rights. Plus, it ensures the job is done right the first time—saving you money and stress in the long run.
