Plumbing permits across Greater Houston

Your plumber's license comes from the state. Your permit comes from wherever your address sits: the City of Houston, a suburban city, or the county.

A plumbing license is statewide: anyone doing plumbing work on your home needs one from the Texas State Board of Plumbing Examiners, whichever city you live in. source

Permits are local. Inside a city, that city's permit office decides which jobs need a permit and which code applies. Houston uses amended Uniform Plumbing Code rules; several suburbs use the International Plumbing Code instead. source

Unincorporated areas such as Cypress and much of Spring fall under county rules. Harris County's permit office handles development permits under its floodplain rules and septic permits; its published FAQ does not describe a plumbing permit program. Water and sewer there usually come from a municipal utility district. source
