Thinking about fixing a leaky faucet or installing a new water heater in your Texas home? You might be wondering: “Do you need a license to do plumbing in Texas?” It’s a smart question—because getting it wrong could mean fines, safety hazards, or even voided home insurance. Whether you’re a homeowner, a handyman, or an aspiring plumber, understanding Texas plumbing laws is essential. Let’s break it all down clearly and confidently.
Is a Plumbing License Required in Texas?
Yes—generally, you do need a license to perform plumbing work in Texas, but there are important exceptions depending on who you are and what kind of work you’re doing.
Since September 2023, the Texas Department of Licensing and Regulation (TDLR) has resumed full oversight of plumbing licensing after a brief deregulation period. This means that anyone performing plumbing services for compensation must hold a valid state-issued license—unless they fall under specific exemptions.
💡 Key Fact: According to TDLR, unlicensed plumbing work can result in fines up to $5,000 per violation and potential legal liability if something goes wrong.
Who Needs a Plumbing License in Texas?
Licensed Professionals
If you’re offering plumbing services for pay, you must be licensed by TDLR. This includes:
Installing or repairing water supply lines
Working on drainage or vent systems
Installing water heaters, fixtures, or gas lines
Performing any work that affects the potable water system
Exemptions: When You Don’t Need a License
Texas law allows a few key exemptions:
Homeowners doing work on their own primary residence
You can legally do your own plumbing if you live in the home and aren’t renting it out.
However, you must still comply with local building codes and obtain permits where required.
Farm or ranch owners working on agricultural property
Plumbing work on property used solely for farming or ranching may be exempt.
Certain government or utility employees
Workers employed directly by municipalities or utility companies may be exempt under specific conditions.
⚠️ Warning: If you’re a handyman or contractor doing plumbing as part of a larger job (e.g., bathroom remodel), you still need a plumbing license unless you subcontract to a licensed plumber.
Types of Plumbing Licenses in Texas
Texas offers several license levels based on experience and scope of work:
Apprentice
None (must be registered)
Work under direct supervision of a licensed plumber
Journeyman
4,000+ hours (≈2 years)
Install, repair, and maintain plumbing systems independently
Master Plumber
8,000+ hours (≈4 years) + Journeyman license
Design systems, pull permits, supervise others, run a business
To qualify, you must:
Be at least 18 years old
Pass required exams (trade and law)
Provide proof of work experience
Pay application and exam fees (typically $100–$150)
All licenses must be renewed every two years with continuing education credits.
Operating without a plumbing license in Texas isn’t just risky—it’s illegal. Consequences include:
Fines: Up to $5,000 per violation (TDLR enforcement)
Cease-and-desist orders: You may be forced to stop work immediately
Lawsuits: If faulty work causes water damage or health issues, you could face civil liability
Insurance issues: Homeowners’ insurance may deny claims for unlicensed work
📊 Real-World Example: In 2024, a San Antonio handyman was fined $12,000 after TDLR found he’d installed gas lines without a license—leading to a minor carbon monoxide leak. The homeowner’s insurance refused to cover repairs.
