Entry tier; works under direct Journeyman or Master supervision. Cannot pull permits.
Texas Plumbing License Guide 2026: Master, Journeyman, and Tradesman Tiers
Texas regulates plumbers through the Texas State Board of Plumbing Examiners (TSBPE), a separate agency from the rest of the construction trades licensing. The Texas structure is unusual: you progress through three tiers (Tradesman → Journeyman → Master), and each tier has a separate exam, separate experience requirement, and separate authorities. Master Plumbers can pull permits independently; Journeymen cannot.
Texas is the largest US plumbing market by revenue, generating an estimated $14.8 billion in plumbing services in 2025 per IBISWorld. The state license is relatively affordable compared to California, with first-year total cost typically under $1,200 if you already have the experience. The bottleneck is the experience requirement: 8,000 hours (about 4 years full-time) of supervised work before sitting for the Master exam.
This guide covers the three tiers, the full TSBPE application process, the actual exam content, the medical gas and water supply protection specialties that command premium rates, and how to operate compliantly as a master plumber across the Texas grid system (which fragments locally between Houston, DFW, San Antonio, Austin permitting jurisdictions).
License Classifications

Step-by-Step Application Process
1. Register as an Apprentice (year 1-4)
Before you can sit for any plumbing exam in Texas, you must register as an apprentice with TSBPE and accumulate documented work hours under a Master Plumber. Apprentice registration is $30 annually. Your sponsoring Master must submit quarterly work logs. 8,000 verified hours is the threshold for Tradesman + Journeyman path. Most apprentices reach this in 4 years of full-time work; faster if you work 50+ hour weeks.
2. Pass the Tradesman exam (after 4,000 hours, optional)
The Tradesman exam is optional but recommended. It lets you do limited work in 1- and 2-family residential up to a specific scope. $115 exam fee. 50-question test, 70% to pass. Open-book on the Texas Plumbing Statutes only; closed-book on plumbing code (2018 UPC with state amendments). Most apprentices skip this and go straight to Journeyman after 8,000 hours.
3. Pass the Journeyman exam (after 8,000 hours)
After 8,000 verified work hours, file the Journeyman application ($145) and sit for the exam. 80-question test, 70% to pass, 4 hours. Covers plumbing code, gas piping, drainage and venting calculations, fixture sizing, water heaters, water supply pressure and sizing. PSI administers; sites in all major Texas metros plus border cities. Journeymen can work on any plumbing system but cannot pull permits or operate a business.
4. Wait the mandatory year as Journeyman
Texas requires 1 year as a registered Journeyman before you can sit for the Master exam. This year cannot be waived. Use it to study and bank money - Master exam fees and bond costs hit $1,500+ in your first year of independent operation.
5. Pass the Master exam
Master exam is $200, 80 questions, 70% to pass, 4 hours. Covers everything on the Journeyman exam plus business law, contracts, Texas Plumbing License Law (Chapter 1301 Occupations Code), employee management, and advanced calculations. Pass rate is approximately 56% for first-time test takers per TSBPE 2024 data. Most successful applicants study 80-120 hours.
6. Register as Master Plumber + get a Responsible Master Plumber (RMP) endorsement
After passing the Master exam, register as a Master Plumber ($175). If you want to operate your own plumbing company in Texas, you also need the Responsible Master Plumber (RMP) endorsement, which is an additional registration with TSBPE that authorizes you to pull permits in the company name. RMP endorsement is $250. Your company gets a separate Master Plumber number printed on contracts and trucks.
7. File insurance and bond
Texas does not require a state bond for plumbing contractors. Some Texas cities (Houston, San Antonio, Plano) require local bonds of $5,000-25,000 for permit pulling within their jurisdiction. General liability insurance is not required by TSBPE but is required by every commercial general contractor you would sub-contract under. Industry standard is $1M general liability + $1M auto, typical annual premium $1,800-3,500.

Continuing Education + Renewal

CE must be from a TSBPE-approved provider. Renewal cycle is annual; renewal fees lapse after 30 days late with $50 late fee. License is suspended 60 days after expiration. Reinstatement requires showing all back CE plus a $250 reinstatement fee. Approved CE providers include PHCC Texas, IAPMO online courses, and accredited community college continuing education programs.
Common Pitfalls to Avoid
- Letting your apprentice registration lapse. TSBPE will not count work hours during a lapsed period.
- Failing to obtain RMP endorsement before operating a plumbing business. Master license alone is not enough - you cannot pull permits in your company name without RMP.
- Skipping the mandatory 1-year Journeyman period before Master exam. TSBPE rejects Master applications submitted earlier; fee is non-refundable.
- Working in Houston, San Antonio, or other jurisdictions with local bond requirements without filing the local bond. Local permit offices verify with the state license database before issuing permits.
- Forgetting CE hours. The most common reason for Texas plumbing license suspension is missing the 6-hour annual CE.
- Operating across jurisdictions without checking local registration requirements. Some Texas cities (Plano, Austin, Dallas) require separate plumbing contractor registration on top of state license.

Frequently Asked Questions
Do I need a separate license for each Texas city?
You need a state plumbing license (TSBPE) plus city-level contractor registration in some metros. Houston requires a local Master Plumber registration ($75 annual) on top of state license. Plano, Austin, and Dallas have similar but different local requirements. San Antonio requires bond posting at the city level. Always check the local permit office before bidding work in a new city.
Can I get a Texas Master Plumber license through reciprocity?
Texas has limited reciprocity. Oklahoma, Arkansas, Louisiana, and New Mexico Master Plumbers can apply for a Texas Master Plumber license without re-testing if they have 2+ years of active licensed master experience in the reciprocating state, no disciplinary history, and pay the standard application fees. All other states must take the Texas exams.
How much does a Master Plumber make in Texas?
Texas Master Plumber operating their own company: median net income $135,000-185,000 annually per 2024 BLS + IRS Schedule C data, with top-quartile master plumbers in Houston and Dallas exceeding $250,000 net. Master Plumbers employed by a company (not owning one) typically earn $85,000-115,000. Specialty endorsements (MGPI, WSPS) add 15-30% to hourly rates.
How long does the entire path from apprentice to Master take?
Minimum 5 years from registration to Master endorsement: 4 years apprenticeship (8,000 hours), pass Journeyman exam, 1 year mandatory as Journeyman, pass Master exam. Most plumbers take 6-8 years because work hours accumulate slower than expected (vacation, slow weeks, illness, training time that does not count toward 8,000).
Is the Medical Gas Piping Installer (MGPI) endorsement worth it?
For plumbers in Houston, Dallas, San Antonio, Austin: yes. Medical facilities pay premium rates for MGPI-certified installation work, typically $95-145/hr vs $75-115/hr for general commercial plumbing. The endorsement requires ASSE 6010 certification (separate, $1,200 course + exam) on top of the TSBPE endorsement fee. ROI is usually achieved within 6 months of certification through dental office, surgery center, and hospital work.
What permits can a Journeyman pull?
None in their own name. Journeymen can work on plumbing systems but cannot pull plumbing permits. All permits must be pulled by a licensed Master Plumber with RMP endorsement. This is the primary reason Journeymen advance to Master - independent business ownership requires Master + RMP.
