Required documents

• RequiredSign Permit application materials (submitted by email)Re-chased 2026-07-23: the County's old standalone Sign Permit Application PDF (DocumentCenter View 957) is confirmed permanently retired, not merely broken -- the County's current 'Application Forms' page (827/Application-Forms) lists 26 specific planning-permit application PDFs by document ID (Variance, Conditional Use Permit, Final Site Plan, Sketch Plan, Temporary Use Permit, etc.) and Sign Permit is not among them. In its place, a live 'Sign Permit Checklist' (DocumentCenter View 22930, current as of 6/2026) is now the operative submittal document -- confirmed live 2026-07-23, it lists the required attachments and states 'Review timeframes are ESTIMATED to be 7 business days.' Per the County's official Planning & Zoning page (summitcountyutah.gov/307/Planning-Zoning), under 'How to apply for a Planning Permit': 'To apply for a planning permit, please email the application and required materials to planningapplications@summitcountyutah.gov' -- confirming intake for Planning Division permit types (which include Sign Permits, per this entry's Development Code sourcing) is by email, not the Building Division's EPROCESS360 portal.

• If no building permit was required (e.g., a pure change of use with no construction), the use itself must conform to the Development Code and all other applicable statutes/ordinances, or qualify as a valid legal nonconforming use under Section 10-8-1 (Section 10-3-20(J)(1)(b))
