PLUMBING x HOUSTON x TEXAS

Plumbing contractors in Houston, Texas.

Plumbing contractors operating in Houston, Texas, must navigate a dual-layer regulatory environment. At the state level, the Texas State Board of Plumbing Examiners (TSBPE) governs individual licensing and professional conduct. All plumbing work must be performed by or under the direct supervision of a licensed professional, with a Responsible Master Plumber (RMP) overseeing the business entity.

Locally, the City of Houston Permitting Center manages the permitting and inspection process. Contractors must register their state license with the city to pull permits for residential or commercial projects. Adherence to the Uniform Plumbing Code is mandatory, and failure to secure permits or pass inspections can result in significant fines and legal liability.
