South Jordan, UT Building Safety: Plumbing Permits (2026)

South Jordan adopts the International Plumbing Code (IPC) with Utah state amendments under Title 15 of the Municipal Code. Permits are required for installing or altering any water supply, drainage, waste, vent (DWV), gas piping, or water heater. Like-for-like replacement of fixtures (faucets, toilets, sinks) by the occupant in a single-family home typically does not require a permit, but water heater swaps and any work that modifies piping do require one. All non-exempt work must be performed by a plumber licensed by Utah DOPL unless the homeowner is performing it on their owner-occupied primary residence. Inspections include rough-in (before walls are closed) and final. South Jordan's water and sewer system is operated by the city — backflow prevention devices are required on irrigation systems and commercial connections, and cross-connection control is enforced. Permit fees are based on valuation or fixture count depending on project type. Working without a permit can result in double fees, required exposure of concealed work for inspection, and stop-work orders.
