Texas Plumbing Legislation, Codes, and Guidelines

State Statutes and Codes

Plumbing regulation in Texas is primarily governed by the Plumbing License Law, which is codified under Chapter 1301 of the Texas Occupations Code. This statute mandates that plumbing work be performed by or under the direct supervision of a licensed plumber, with specific exceptions for homestead owners. Regarding technical standards, the Texas State Board of Plumbing Examiners (TSBPE) adopts plumbing codes to ensure the proper design, installation, and maintenance of plumbing systems. While the state adopts specific codes as a baseline, Texas law allows municipalities and political subdivisions to adopt and amend plumbing codes to address local concerns, provided those amendments do not substantially vary from state rules or laws. Consequently, local jurisdictions may choose between recognized standards, such as the International Plumbing Code (IPC) or the Uniform Plumbing Code (UPC), and apply their own local amendments.

Primary State Board

The Texas State Board of Plumbing Examiners (TSBPE) is the primary state agency responsible for the regulation of the plumbing industry in Texas. Its authority includes the licensing and examination of plumbing professionals, the enforcement of the Plumbing License Law, the adoption of plumbing codes for areas not otherwise regulated, and the oversight of continuing professional education for licensees.
