How to Get Your Plumbing Contractor License in Texas

Texas does not issue a plumbing contractor license. What it does instead is license individual plumbers at different skill levels, then add a separate designation for those who want to run a plumbing business and take contracts under their own name. That designation is called the Responsible Master Plumber (RMP), and it’s what allows you to operate a plumbing business in Texas.

To get there, most plumbers move through four stages:

• Registered Apprentice
• Journeyman Plumber
• Master Plumber
• Responsible Master Plumber (RMP)

The Texas State Board of Plumbing Examiners (TSBPE) oversees all of it.

If you’re searching for a Texas plumbing contractor license, what you’re actually looking for is the Responsible Master Plumber (RMP) designation.

For most licensed plumbers, reaching the RMP designation takes at least five to seven years, depending on apprenticeship hours and training path. That timeline starts on the day you register as an apprentice — not the day you first pick up a pipe wrench.

1. Register as a Plumber’s Apprentice
2. Complete 8,000 hours of field experience
3. Pass the Journeyman Plumber exam
4. Work as a Journeyman for 1 to 2 years
5. Pass the Master Plumber exam
6. Obtain $300,000 in commercial liability insurance
7. Apply for the Responsible Master Plumber designation

Start as a Registered Apprentice

Before any of this counts, you need to register as a Plumber’s Apprentice with the TSBPE. You have to be at least 16 years old. Registration requires a completed application, a small fee (check tsbpe.texas.gov for current amounts), and fingerprint data. That last part is a one-time requirement for everyone in the Texas plumbing licensing system.

Don’t skip this step or delay it. The TSBPE is explicit: any hours you work in the plumbing trade before you’re registered as an apprentice don’t count toward the experience requirements for higher licenses. Those hours are gone forever. Register first.

As an apprentice, you can assist with plumbing installations under the direct supervision of a licensed plumber. Direct means that licensee is on-site with you. If they leave, you’re digging trenches.

Get Your Journeyman Plumber License

To sit for the Journeyman Plumber exam, you need at least 8,000 hours of documented plumbing trade experience as a registered apprentice or Tradesman Plumber-Limited, certified by your employer on a TSBPE Employer Certification Form. You also need a 48-hour training course approved by the TSBPE, or enrollment in a program approved by the U.S. Department of Labor Office of Apprenticeship. If you already hold a Journeyman or Master Plumber license from another state, that training requirement is waived.

You’ll pay separate application, examination, and licensing fees. Current amounts are listed at tsbpe.texas.gov.

Once licensed, you can legally perform plumbing work for employers throughout Texas, but you still cannot operate your own plumbing business.

Get Your Master Plumber License

The Master Plumber exam is the next gate. To qualify, you need to have held your Journeyman Plumber license for at least two years, or at least one year if you completed a DOL Office of Apprenticeship-approved training program.

The exam involves fees paid both to the TSBPE when you apply and to Pearson VUE on test day. Current fee amounts are at tsbpe.texas.gov.

A Master Plumber may install, change, repair, and renovate plumbing, and can directly supervise apprentices and Tradesman Plumber-Limited licensees on most job sites. Passing the Master exam does not authorize you to operate a plumbing business. You still need the Responsible Master Plumber designation.

Get Your Responsible Master Plumber (RMP) Designation

This is what most people searching for a “plumbing contractor license” are actually after. The Responsible Master Plumber (RMP) designation is what lets you operate a plumbing company, pull permits, and take contracts under your own license number. Per the TSBPE, the RMP is responsible for the general supervision and management of plumbing work performed under contracts secured under that license, whether the workers are employees or subcontractors.

To get it, you must be a licensed Master Plumber in good standing and carry at least $300,000 in commercial general liability insurance. You submit the application, a Certificate of Insurance signed by your agent, and the required fee. The TSBPE offers online applications, which process faster than mail. See tsbpe.texas.gov for current amounts.

Once you have the RMP designation, the responsibilities are real. You’re on the hook for making sure everyone on your jobs is properly licensed or registered. Permits, inspections, direct supervision wherever registrants are working. Your company name and RMP license number have to appear on all service vehicles. One RMP designation, one company. You can’t hold it for multiple businesses at the same time.

The paperwork obligations start immediately too. Every estimate, invoice, and receipt you send a customer must include your RMP name, license number, and the TSBPE disclosure — in at least 12-point font, on the first page, every time. It’s one of the more commonly missed compliance requirements once a plumber starts running their own jobs.

Keep Your License Current

All TSBPE licenses renew annually. You need six hours of continuing professional education each year to be eligible. If your license lapses for more than two years, you can’t just renew it. You’re back to square one: re-register as an apprentice, meet current eligibility requirements, and take the exams again from the bottom.

Set renewal reminders well before your expiration date. Once you’re running a plumbing business, keeping estimates, invoices, customer records, and licensing information organized can save time during renewals and audits. Those are the same records that get pulled when a complaint is filed or an inspection happens — the cleaner your paperwork, the faster those situations resolve.

Verify the Current Requirements

Texas plumbing license requirements and fees can change. Always verify the current requirements directly with the TSBPE before submitting any application at tsbpe.texas.gov.
