If you’re a homeowner trying to fix a leaky faucet—or a handyman looking to take on plumbing jobs—you might be wondering: Can you work on plumbing without a license in Texas? The short answer? It depends—but doing unlicensed plumbing work in Texas can come with serious legal and financial consequences. In this guide, we’ll break down exactly what’s allowed, what’s not, and how to stay on the right side of the law while protecting your home or business.
Is Plumbing Work Regulated in Texas?
Yes—very strictly. As of September 1, 2023, Texas transferred oversight of plumbing licensing from the Texas State Board of Plumbing Examiners (TSBPE) to the Texas Department of Licensing and Regulation (TDLR). This shift reinforced the state’s commitment to public safety, water conservation, and code compliance.
According to the TDLR, any plumbing work that affects public health, sanitation, or the potable water supply must be performed by a licensed plumber. This includes installing, repairing, or altering piping systems for water, gas, sewage, or drainage.
“Plumbing isn’t just about pipes—it’s about preventing contamination, ensuring clean water, and avoiding structural damage,” says Carlos Mendez, a master plumber and TDLR compliance advisor.

Can Homeowners Do Their Own Plumbing in Texas?
Yes—with important limitations. Texas law allows property owners to perform plumbing work on their own primary residence, provided they:
- Live in the home (it’s your primary residence, not a rental or flip property).
- Obtain all required permits from your local municipality.
- Pass all inspections by city or county officials.
- Do not hire unlicensed individuals to “help” under your name (this is illegal).
However, you cannot legally do plumbing work on rental properties, commercial buildings, or homes you don’t occupy—even if you own them.
💡 Real-life example: In 2024, a San Antonio landlord was fined $5,000 after a tenant reported repeated sewage backups caused by DIY plumbing repairs. The city cited the owner for unlicensed work on a non-owner-occupied property.
What Types of Plumbing Work Require a License?
Not all plumbing tasks are equal. Here’s a quick breakdown:
| Task | License Required? | Notes |
|---|---|---|
| Fixing a dripping faucet (in your own home) | ❌ No | Permitted for owner-occupants |
| Installing a new water heater | ✅ Yes | Requires permit & licensed pro |
| Replacing a toilet | ❌ No (if in owner-occupied home) | Must comply with local codes |
| Running new gas lines | ✅ Yes | High-risk; always requires license |
| Repairing sewer lines | ✅ Yes | Even partial repairs need a license |
⚠️ Warning: Many cities (like Austin, Dallas, and Houston) have stricter rules than the state minimum. Always check with your local building department before starting any project.
What Happens If You Work Without a License?
The penalties for unlicensed plumbing in Texas are not just fines—they can escalate quickly:
- Fines: Up to $5,000 per violation (TDLR can pursue civil penalties).
- Stop-work orders: Your project halts immediately.
- Permit denial: Future renovation permits may be denied.
- Insurance voidance: Homeowners insurance may refuse to cover water damage from unlicensed work.
- Legal liability: If faulty plumbing causes mold, flooding, or injury, you could face lawsuits.
In 2023, TDLR reported over 1,200 enforcement actions against unlicensed plumbing contractors statewide—a 17% increase from 2022.
Are There Any Exceptions to the Licensing Rule?
Yes, but they’re narrow:
- Homeowners on primary residences (as noted above).
- Farm or ranch owners: Minor plumbing on agricultural properties may be exempt, but only if it doesn’t connect to public water/sewer systems.
- Licensed professionals in related trades: A licensed HVAC technician may handle gas line connections if their license explicitly includes gas piping—but not full plumbing systems.
There is no “handyman exemption” in Texas for plumbing. Unlike some states, Texas does not allow handymen to perform plumbing beyond very minor cosmetic fixes (e.g., replacing a showerhead).
How to Get a Plumbing License in Texas (Step-by-Step)
If you’re serious about plumbing as a career or side business, here’s how to get licensed through TDLR:
- Complete a plumbing apprenticeship (minimum 4 years / 8,000 hours under a master plumber).
- Pass the Journeyman Plumber exam (150 questions, 4-hour time limit).
- Apply through TDLR with proof of experience, exam results, and $115 fee.
- Renew every 2 years with 8 hours of continuing education.
💡 Pro tip: TDLR offers a free online portal to check license status, file complaints, or apply.
You cannot legally advertise or accept plumbing jobs until your license is active and displayed.
Pros vs. Cons: DIY Plumbing in Texas
| Pros | Cons |
|---|---|
| Saves money on simple fixes | Risk of code violations |
| Full control over your project | No warranty or insurance protection |
| Sense of accomplishment | Potential for costly mistakes (e.g., water damage) |
| Legal if you follow owner-occupant rules | May lower home resale value if not permitted |
Ask yourself: Is saving $150 on a water heater install worth risking $10,000 in water damage? For most, the answer is no.
FAQ: Common Questions About Plumbing Licenses in Texas
Q1: Can I help my friend with their plumbing as a favor?
A: Only if you’re not being paid—and even then, only if they live in the home. If you’re doing the work (even unpaid), you’re still technically violating TDLR rules if the work requires a license. Best to avoid it.
Q2: What’s the difference between a Journeyman and Master Plumber license?
A: A Journeyman can work under supervision; a Master can run their own business, pull permits, and supervise others. You need 1 year of experience as a Journeyman before applying for Master status.
Q3: Do I need a license to unclog a drain?
A: If you’re using a plunger or drain snake in your own home, no. But if you’re using motorized equipment, chemicals, or working on a sewer line—even as a homeowner—you may need a permit and professional help.
Q4: Can a general contractor do plumbing without a plumbing license?
A: No. General contractors in Texas must subcontract licensed plumbers for all plumbing work. Performing plumbing without a plumbing license is illegal, even with a GC license.
Q5: How do I report unlicensed plumbing work?
A: File a complaint with TDLR online or call (800) 803-9202. Anonymous reports are accepted.
Q6: Are online plumbing courses enough to get licensed?
A: No. Texas requires hands-on, supervised experience. Online courses can help prepare for exams but don’t count toward your 8,000-hour requirement.
Conclusion: Stay Safe, Stay Legal
So, can you work on plumbing without a license in Texas? Technically, yes—if you’re an owner-occupant doing minor, permitted work on your own home. But for everything else—rentals, commercial jobs, gas lines, sewer repairs—the answer is a firm no.
Getting it wrong doesn’t just risk fines; it risks your home, your health, and your reputation. When in doubt, hire a licensed plumber or contact TDLR for guidance.
