Texas plumbing license: apprentice, tradesman, journeyman and master

You start by registering as a Plumber's Apprentice with the Texas State Board of Plumbing Examiners (TSBPE). Your hours only count after that. With 4,000 hours you can take the Tradesman Plumber-Limited exam, and with 8,000 the Journeyman exam, each a written test plus a hands-on practical. A Texas plumbing license renews every year, after 6 hours of continuing education.

How do you get a Texas plumbing apprentice license?

Strictly it's a registration, not a license. As of October 2026 you must be at least 16, send the TSBPE an application with a $15 fee, and give fingerprints once. You can then learn and help with plumbing, but only with a licensed plumber on site the whole time. The TSBPE says you must register before you can start counting hours.

Drain cleaning and residential utility work are separate registrations added on top of the apprentice registration.

Texas plumbing licenses compared

A tradesman can work on one- and two-family homes under a Responsible Master Plumber. On other buildings, a journeyman or master has to be on the job site. The written exam fee is paid to Pearson VUE on top of these: $68.50 for tradesman and journeyman, $128.50 for master.

The Master Plumber page says 2 years as a journeyman, but the August 2025 candidate handbook still says 4 years, and lists a $175 application fee instead of $25. Check with the TSBPE at (512) 936-5200 before you apply.

The Texas plumbing exam: written, then hands-on

ExamWrittenPractical
Tradesman Plumber-Limited85 questions, 120 minutes6 parts, 240 minutes
Journeyman Plumber100 questions, 120 minutes6 parts, 240 minutes
Master Plumber308 questions, 360 minutes plus an optional 30-minute breakNone

You need 70%, and you haven't passed until both parts are passed. The written test is at Pearson VUE centers. The practical is only at the TSBPE's sites in Austin and Waco, and you book it at least ten days ahead.

On the journeyman practical you cut and join PVC, copper, threaded steel and cast iron, judge water heater installations, and design a two-story drain and vent system, then build it in a scale model. The board supplies the materials. Short pants and open-toed shoes aren't allowed. If you already hold a tradesman license, you skip the practical when you move up.

You study the Texas plumbing law and board rules plus one code: the 2018 International Plumbing Code with the 2018 International Fuel Gas Code, or the 2018 Uniform Plumbing Code.

Texas plumbing inspector license

Inspectors are licensed by the same board. You need a high school diploma or GED and 500 hours of training and experience in the plumbing industry, unless you already hold a Texas master or journeyman plumber, engineer or architect license. The exam fee is $55, and so is the license.

Keeping and checking a Texas license

Your first license gets a random expiry date 6 to 18 months after you pass, then it renews yearly. Renewal fees and the late rules are on the renewal page, and the TSBPE's public search shows whether a plumber is licensed.
