Irion County, Texas Plumbing Permit Requirements
Irion County, Texas, does not appear to have a county-level Building & Safety Division that issues general building permits for ordinary construction in unincorporated areas. Instead, the county's regulations focus on specific aspects of development.
- Jurisdiction: The primary regulations found for unincorporated Irion County pertain to subdivision plat approval and manufactured home rental community (MHRC) review, as outlined in the 2025 Subdivision and Manufactured Home Rental Community Regulations.
- Unincorporated Areas: For properties in unincorporated areas, there is no evidence of a countywide general building permit requirement for standard construction. However, applicants must address floodplain status, and the county's floodplain management regulations remain applicable.
- Plumbing and Septic Systems: Permits for On-Site Sewage Facilities (OSSF) or septic systems must currently be obtained directly from the Texas Commission on Environmental Quality (TCEQ) Region 8 office, as Irion County is not the designated permitting agent for these systems.
- State Plumbing Code: Texas officially adopted the 2018 International Plumbing Code (IPC) as the foundation for its statewide plumbing regulations. Local jurisdictions, including counties, have the authority to adopt, amend, or add to the statewide plumbing code to address local needs. However, in unincorporated areas where no specific county plumbing code has been adopted, plumbing must be installed in accordance with a plumbing code adopted by the state. All plumbing work in Texas must be performed by or under the direct supervision of a licensed plumber, with a narrow homestead exemption for owner-occupied, single-family residences.

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.
