Plumbing in Stockton
Check the calendar before you drive to Stockton's Permit Center. It's at 501 W. Weber Ave., Building 2, First Floor, open Monday to Friday from 8:00 to 4:30, but it closes on alternate Fridays, and the first Friday runs 8:00 to 12:00 only. Permit technicians answer at (209) 937-8561 during those hours. Call first. The City Municipal Utilities Department serves much of Stockton but not all of it, so check the name on your water bill.
It matters for scale. The city's 2025 water report averages 242 mg/L of hardness in its groundwater, with readings from 117 to 351, against 53 from the Delta Water Treatment Plant and 58 from the SEWD surface supply. Ask which source feeds your street before you pay for a softener. On the city system, send water questions to WaterFacts@stocktonca.gov or call (866) 786-5987. Smell gas? Leave the house, call 911, then call PG&E at 1-800-743-5000.
Skip the Permit Center drive. Through the Accela Citizen Access portal, the city says you can apply, pay fees, check status and schedule inspections at any time, and it lists over-the-counter plumbing permits. For the cost, send the city's Building Permit Fee Estimate Request form, then compare the answer with the permit line on the company's quote.
