Yes. Any plumbing work beyond simple fixture replacement requires a permit in Utah municipalities — new construction, bathroom additions, remodels that relocate drain or supply lines, and water heater replacement in many jurisdictions. Two plumbing inspections are standard: rough-in inspection after pipes are installed but before walls close (including supply pressure test), and final inspection after fixtures are set and operational. RainFire Builders pulls all required plumbing permits, coordinates both inspections, and never closes walls before rough-in inspection approval — a commitment that protects both the homeowner and the project.
