Do I need a permit for addition or structural alteration in Unincorporated Salt Lake County?

Permit required

Yes. In Utah, addition or structural alteration generally requires a permit, and Unincorporated Salt Lake County is no exception.

Additions and structural alterations are regulated statewide under the 2021 IRC as amended by Utah Code 15A-3-201 through 15A-3-206. Utah's IRC amendments let the building official inspect insulation and the exterior wall envelope, and Utah's Chapter 11 energy rules require verification by inspection before interior finishes are installed. If a county building inspection cannot be made within three business days of a request, Utah law lets the applicant use a third-party inspection firm from the county's approved list (17-79-810 and 15A-1-105). Owner-builders must file the state Owner/Builder Certification Agreement with the building department.
