Statewide rules that apply here
Texas plumbing licenses come from the Texas State Board of Plumbing Examiners (TSBPE). There are four license types: Tradesman Plumber Limited, Journeyman Plumber, Master Plumber and Plumbing Inspector. Licenses renew every year, and every licensee needs six hours of continuing professional education to renew. (source: Texas State Board of Plumbing Examiners)
A property owner does not need a plumbing license to do plumbing in the property owner's homestead (Occupations Code 1301.051). Your city can still require a permit and inspection. (source: Texas Legislature)
