Do I need a permit for bathroom remodel in Unincorporated Wasatch County?

It depends. Whether bathroom remodel needs a permit in Unincorporated Wasatch County comes down to the details of your project.

Tiling, painting, cabinets, countertops, and similar finish work are exempt under Utah's adopted IRC R105.2, but moving drains or supply lines, adding circuits or fans, or moving walls needs a permit. Utah sets its own lavatory spacing: a lavatory may not be set closer than 12 inches from its center to a side wall, with a 24 by 21 inch clear space in front (IRC P2705 as amended by 15A-3-205). Minor plumbing incidental to repairing a fixture is exempt from licensing only if no water, soil, waste, or vent piping is modified; plumbing system work on a handyman project must be done by a licensed plumbing contractor (58-55-305). Utah's amended IRC adds accessory dwelling units to the smoke and carbon monoxide alarm rules that apply when permitted alterations, repairs, or additions occur, and requires carbon monoxide alarms on each level of the dwelling unit where they are required (IRC R314.2.2, R315.2.2, and R315.3 as amended by 15A-3-202). This remodel moves plumbing, adds a tub or shower, or changes wiring, exhaust venting or walls. Like-for-like fixture swaps are the part of a bathroom remodel most often exempt; moving pipes and new wiring are not. Plumbing and electrical work each normally need their own permit and rough-in inspection before the walls are closed, so schedule inspections before drywall or tile backer goes up. Bathrooms have specific electrical safety rules, such as ground-fault protection on outlets, which the electrical inspection checks.
