Thinking about becoming a plumbing inspector in Texas? You’re not alone. With growing infrastructure demands and strict building codes, qualified plumbing inspectors are in high demand across the Lone Star State. But how do you get a plumbing inspector license in Texas? The process can feel overwhelming—but don’t worry. This guide breaks it down clearly, step by step, so you can start your career with confidence and compliance.
What Is a Plumbing Inspector in Texas?
A plumbing inspector in Texas is a licensed professional authorized to review, evaluate, and approve plumbing installations in residential, commercial, and industrial buildings. Their role ensures that all systems comply with the Texas State Board of Plumbing Examiners (TSBPE) regulations and the International Plumbing Code (IPC) adopted by the state.
According to the U.S. Bureau of Labor Statistics, employment for construction and building inspectors—including plumbing inspectors—is projected to grow 3% from 2024 to 2034, faster than average, driven by urban development and aging infrastructure.
💡 Fun fact: Texas has over 170,000 licensed plumbers—but only a fraction hold inspector credentials, making this a niche with strong earning potential.
Who Regulates Plumbing Inspectors in Texas?
The Texas State Board of Plumbing Examiners (TSBPE) oversees all plumbing-related licenses, including inspector certifications. As of 2026, TSBPE remains the sole authority—even though there were legislative discussions in prior years about its potential dissolution. Always verify current status via the official TSBPE website.
For background on regulatory frameworks, see Wikipedia’s overview of occupational licensing in the U.S., which explains why states like Texas maintain strict credentialing for public safety roles.
Step-by-Step: How to Get a Plumbing Inspector License in Texas
Step 1: Meet the Basic Eligibility Requirements
Before applying, you must satisfy these mandatory prerequisites:
- Be at least 18 years old
- Have a high school diploma or GED
- Hold an active Master Plumber license in Texas (or equivalent out-of-state license with reciprocity)
- Have at least 4 years of verifiable plumbing experience, with 2+ years in Texas under a licensed master plumber
⚠️ Note: You cannot skip the Master Plumber license. Texas does not allow direct entry into inspector roles without this foundational credential.
Step 2: Gain Relevant Inspection Experience (Recommended)
While not always required, TSBPE strongly recommends hands-on experience with code enforcement or plan review. Many successful applicants work alongside city or county building departments before applying.
Consider volunteering or interning with local municipalities—this builds credibility and deepens your understanding of real-world code application.
Step 3: Complete Required Training (If Applicable)
As of 2026, Texas does not mandate pre-licensing coursework for plumbing inspectors. However, taking a code review course (e.g., through ICC or ASSE) can significantly boost your exam readiness.
Popular options include:
- ICC’s Plumbing Inspector Training (B2 Certification prep)
- Texas A&M Engineering Extension Service (TEEX) courses
These aren’t required by TSBPE but are highly valued by employers.
Step 4: Submit Your Application to TSBPE
Visit the TSBPE online portal and complete the Plumbing Inspector Application. You’ll need:
- Proof of Master Plumber license
- Employment verification forms (signed by supervising plumbers)
- Application fee: $115 (as of January 2026)
- Background check consent
Processing typically takes 2–4 weeks.
Step 5: Pass the Texas Plumbing Inspector Exam
Once approved, you’ll receive an exam eligibility notice. The test is administered by PSI Services at testing centers statewide.
Exam Details:
- Format: 100 multiple-choice questions
- Time Limit: 4 hours
- Passing Score: 70%
- Content Areas:
- Texas Plumbing Code (based on IPC with state amendments)

📚 Pro Tip: Use the TSBPE Exam Reference List—it includes the exact code books allowed during the open-book exam. Bring annotated copies!
Step 6: Receive Your License & Maintain It
Upon passing, you’ll get your Plumbing Inspector license valid for 1 year. Renewal requires:
- $115 renewal fee
- 8 hours of continuing education (including 1 hour on Texas laws/rules)
- Submission before expiration date
Failure to renew on time may require re-examination.
Common Challenges & How to Avoid Them
| Challenge | Solution |
|---|---|
| Failing the exam on first try | Take a practice test; focus on Texas-specific amendments to IPC |
| Incomplete work history documentation | Keep detailed logs of projects, dates, and supervisors |
| Confusion about license types | Remember: Inspector ≠ Master Plumber. You need both. |
| Delays in application processing | Submit early and double-check all forms for accuracy |
Plumbing Inspector vs. Other Licenses in Texas
Not all plumbing credentials are equal. Here’s how they compare:
| License Type | Purpose | Required for Inspector? |

| Journeyman Plumber | Install/repair under supervision | ❌ No |
| Master Plumber | Run a business, pull permits | ✅ Yes |
| Plumbing Inspector | Approve/reject plumbing work | Final goal |
| Backflow Tester | Test cross-connection devices | Optional but helpful |
You must hold a Master Plumber license before pursuing inspector status.
