Plumbing in Denton
Denton's Residential Permits page lists the city's amendments to the 2021 International Residential Code, Building Code, Plumbing Code, Mechanical Code, Fuel Gas Code and Existing Building Code, and to the 2020 National Electrical Code. That's newer than the state's starting point: TSBPE's rule adopts the 2018 UPC and IPC and lets a political subdivision amend for local concerns that don't substantially vary from board rules. Every city over 5,000 residents writes its own plumbing ordinance under Occupations Code 1301.551, with its own permit and plumbing inspector.
You won't find a plumbing fee, a hardness figure or any statement on lead service lines on Denton's pages, so take all three questions to the city's permit office. EPA's federal list pairs City Of Denton, PWSID TX0610002, with the city on the basis of an operator address, and the system serves 150,037 people on surface water. As of the 2020 to 2024 ACS, Denton's median year built is 1997.
