Do you need a permit for ADU Construction in Uintah County?
In Utah, a ADU Construction requires a building permit.
An accessory dwelling unit (ADU) always requires a building permit because it adds a habitable dwelling, including electrical, plumbing, mechanical permits and egress/zoning review. Plans are reviewed under the Statewide (local may vary) code (IRC 2024); apply through Uintah County Community Development before work begins.
