In September 2023, Texas abolished 76 years of mandatory state plumbing licensing — making it one of the only states in the country to voluntarily dismantle a long-standing credentialing system. If you're a plumber in Texas or thinking of starting a plumbing business here, here's what actually changed, what didn't, and why more Texans are getting licensed anyway.
What Happened: HB 1063, Effective September 1, 2023
House Bill 1063, authored by Rep. Brian Harrison (R-Midlothian) and signed by Governor Greg Abbott, passed during the 88th Texas Legislature and took effect September 1, 2023. The bill amended Chapter 1301 of the Texas Occupations Code to make state-level plumbing licensure voluntary rather than mandatory.
Texas had required plumbers to hold a state license since 1947 — 76 years of mandatory credentialing, ended in a single session. The bill was championed by the Institute for Justice and free-market advocates who argued occupational licensing raised barriers to entry without proportionate safety benefits. The Texas Association of Plumbing Contractors (TAPC) and industry groups opposed the change, citing public health and safety concerns.
What TSBPE Now Does
The Texas State Board of Plumbing Examiners (TSBPE) at tsbpe.texas.gov was not abolished. It now operates as a voluntary credentialing body. Specifically:
- Still administers plumbing licensing exams for contractors who want voluntary credentials
- Still sets plumbing codes and technical standards for the state
- Still handles consumer complaints about plumbing work quality
- No longer issues licenses that are legally required to perform plumbing work in Texas
The voluntary credential tiers mirror the former mandatory structure: Apprentice, Tradesman, Journeyman, Master Plumber, and Plumbing Inspector. Verify current fees and application steps directly at tsbpe.texas.gov.
The Surprising Statistic: Licensing Is Up After Deregulation
You'd expect licensing exam volume to crater after the mandate was removed. The opposite happened. According to TSBPE data, licensing exams jumped 111% between 2022 and 2024 — from 4,953 exams in 2022 to 10,447 in 2024. The market responded to freedom with more credentialing, not less.
Why? Because the market still demands it, even if the state doesn't. More on that below.
What Still Applies: City-Level Permits and Requirements
State deregulation does not mean permits disappeared. Every major Texas city still requires plumbing permits for significant work, and those permit systems still effectively screen for competency:
- Houston: The Houston Permitting Center requires contractors to register and designate a qualified plumber to pull permits. This is a local municipal requirement that survived HB 1063 — because it's a city rule, not a state one.
- Dallas: Dallas Building Inspection still requires permits for all significant plumbing work. Contractors pulling permits are expected to demonstrate competency — verify current requirements at dallascityhall.com.
- Austin: Austin Development Services enforces permit requirements and local code compliance regardless of state licensing status.
- San Antonio: San Antonio's Development Services Department continues to enforce permit requirements city-wide.
Major Texas cities effectively still screen for competency through their permit systems. The biggest practical change from HB 1063 is in rural and unincorporated areas — where there's now no state requirement and no municipal permit system. Those areas are now truly unregulated.
The other group most affected: new entrants who previously couldn't navigate the multi-year apprenticeship and exam path required for mandatory licensure. For them, voluntary credentialing is now an on-ramp rather than a gatekeeper.
Why the Market Still Requires It
Even without a legal mandate, the market has effectively re-imposed the requirement through three channels:
- Commercial contracts. General contractors and property managers routinely require TSBPE voluntary credentials as a condition of subcontracting. No credential = no commercial bid opportunities.
- Insurance underwriting. General liability and contractor insurance policies often require demonstrated competency. Insurers may use TSBPE voluntary credentials as an underwriting factor, and an unlicensed plumber who causes property damage faces greater difficulty in insurance claim disputes.
- Banks and SBA lenders. Business financing for plumbing contractors often references state-level credentials, even voluntary ones, as part of creditworthiness assessment.
Federal Requirements That Still Apply
State deregulation didn't change federal law. Two in particular catch Texas plumbers off guard:
- EPA Lead RRP Certification. The EPA's Renovation, Repair, and Painting Rule (40 CFR Part 745) requires any contractor disturbing lead-based paint in pre-1978 homes to be EPA Lead RRP certified. Plumbing work in older Houston, Dallas, or Austin homes frequently triggers this. Certification is through an EPA-accredited provider. See epa.gov/lead.
- OSHA Construction Standards (29 CFR 1926). Federal OSHA regulations covering confined space entry, trenching and excavation, and hazard communication apply to all plumbing work regardless of state licensing status.
Texas vs. Other States
Texas isn't alone in lacking mandatory statewide plumbing licensing — but it's unusual in having abolished one. States without statewide mandatory plumbing license requirements include Kansas, Missouri, Nebraska, and New York (though NYC has some of the strictest local requirements in the country). The difference with Texas: most of those states never had a statewide mandatory system. Texas had one for 76 years and removed it.
What This Means If You're Starting a Plumbing Business in Texas Today
You don't need a TSBPE license to legally operate at the state level. But you almost certainly need one to win commercial work, meet insurance requirements, and pull permits in major cities. Get the voluntary credential anyway. It's your fastest way to differentiate in a newly deregulated market where anyone can now call themselves a plumber.
For homeowners and property managers: always request a TSBPE voluntary credential from any plumber you hire, even though it's no longer legally required. It's still the clearest signal of examined competency and supports insurance coverage if something goes wrong.
