Texas, Lee County Plumbing Permit Regulations and County Ordinances for Unincorporated Areas

Lee County, Texas Plumbing Permit Requirements

In Lee County, Texas, plumbing permits are generally handled by the county's Development Services Department, particularly for properties located in unincorporated areas. A permit is required for the installation, replacement, or relocation of plumbing fixtures or sewer connections. For commercial structures or trade permits valued at $125,000 or more, or those with 250 or more fixture units, a design professional is required. Similarly, an irrigation permit is necessary for lawn irrigation systems connected to a potable water source.

For properties in unincorporated areas of Lee County, a development permit is required for most construction, including plumbing-related work. This applies to residential, commercial, oil and gas pipeline, and water development. Any individual structure exceeding 100 square feet requires a permit, as do all septic systems. If any portion of the property is located within the 1% chance (100-year) floodplain, additional requirements apply, such as flood-proofing measures, engineering studies, and specific documentation like elevation certificates or engineering certifications.

Contractors are encouraged, and in many cases required, to use Lee County's eConnect online permitting system. Paper applications are typically only accepted from owner-builders and must be submitted in person.

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.
