Plumbing in San Antonio
Development Services in San Antonio sets a $57.50 base fee for a plumbing permit on commercial and existing residential work, on its fiscal year 2027 schedule revised October 2026. Each fixture is $8.05, a water heater or vent (gas or electric) is $9.20, a water softener is $19.55, and a gas permit has its own $57.50 base fee. Only a state-registered master plumber can pull a plumbing permit here. The one exception is an existing home that's the owner's homestead, where the owner does the work personally and files a Plumbing Homeowner Affidavit.
Applications go through the BuildSA portal, and the residential page links a No Permit Required list. SAWS posts a 2026 Main System Water Quality Report as a PDF, with separate reports for five smaller systems: Castle Hills, Geronimo Forest, Mountain Laurel, Northeast and Texas Research Park. San Antonio Water System, PWSID TX0150018, is the city's match in EPA's federal list, made from its operator's address rather than a service boundary, and it supplies 2,643,729 people with purchased surface water.
Owner-occupied homes here have a median value of $235,700, and the median year built is 1985 (Census, 2020 to 2024). Hiring someone? TSBPE's public license search takes a name, license number, city or county. The permit pages don't name a plumbing code edition, so put that question to Development Services at 3-1-1 or 210-207-6000.
