How Texas compares
The mean hourly wage for plumbers in Texas is $29.22, 16% below the US mean of $34.70. Texas's estimate uses prices its own plumbers publish, so the wage does not enter it. None of the states bordering Texas has a page here yet, so the table compares it with the national estimate only.
| Area | Estimate | Midpoint | Plumber wage |
|---|---|---|---|
| Texas | $4,100–$8,200 | $6,100 | $29.22 |
| United States | $4,000–$7,500 | $5,800 | $34.70 |
Permits and licensing in Texas
The Texas State Board of Plumbing Examiners licenses and registers plumbers in Texas and adopts the state plumbing codes by rule. License types include Master Plumber and Journeyman Plumber. You can check a plumber's license on the state license search. Plumbing permits come from the city. Houston charges by the fixture, with a minimum fee and an administration fee. Ask your building department how it prices a whole-house repipe.
- City of Houston Permitting Center: $34.24 for the first three plumbing fixtures plus $11.41 for each additional fixture; minimum permit fee $97.56 and a $33.56 administration fee apply. For a house with 2 full baths and 11 fixtures, that comes to $126–$159.
Plumbing code in Texas
The Board's rule 22 TAC 367.2 adopts the 2018 Uniform Plumbing Code and the 2018 International Plumbing Code, and lets political subdivisions adopt a plumbing code with local amendments. Your city or county can add local amendments, so the building department that issues the permit has the final word.

Age of Texas's housing
Half of the housing units in Texas were built before 1994, by the Census Bureau's ACS 2024 1-year count. 12% were built before 1960, when galvanized supply pipe was common. 26% were built from 1980 to 1999, the two Census decades that overlap the years polybutylene pipe was made. Age alone does not tell you what pipe a house has; a plumber or inspector can.
