Can a homeowner do their own plumbing in Texas?

State law says a property owner does not need a plumbing license for plumbing in their own homestead. Most cities still require a permit and inspection, and El Paso only issues trade permits to licensed, registered contractors.

Sources differ. State licensing law exempts a property owner doing plumbing in their own homestead (Occupations Code 1301.051), a person doing air conditioning work in a building they own solely as their home (1302.053), and electrical work "not specifically regulated by a municipal ordinance" done in or on a dwelling by a person who owns and resides in it (1305.003(a)(6)). El Paso's homeowner affidavit says a homeowner may NOT obtain mechanical, electrical, plumbing, irrigation or fire systems permits unless licensed with the state and registered with the city, and that trade permits are only issued to state licensed contractors registered with the city (Ord. No. 18508). The state exemption is about licensing; the city controls its permits. Call El Paso Planning and Inspections before planning DIY trade work.
