Unincorporated Cache County requires a certificate of occupancy / change of occupancy permit for: Required before any building or structure (or portion of one) in unincorporated Cache County is used or occupied, and before any change of occupancy of a building or structure or portion of one is made, per item 7 of the county's Building Permit Application document.; For projects involving new construction, an addition, a remodel, or a commercial tenant improvement, the Certificate of Occupancy is issued following that project's Final Inspection; the same application document states in bold: 'OWNER(S) ARE NOT ALLOWED TO MOVE IN PRIOR TO RECEIVING THE CERTIFICATE OF OCCUPANCY.'; For structures in unincorporated Cache County, a completed and signed Cache County Public Works and Fire District Pre-Occupancy Checklist must be submitted to the Building Division at the time of Final Inspection 'in order to pass the inspection and to receive a Certificate of Occupancy,' per that checklist's own instructions; it is the property owner's or designee's responsibility to obtain the required Public Works and Fire District sign-offs, and the sheet must be available on-site during inspections.; A change in occupancy classification of an existing building (e.g., converting an existing commercial space to a different IBC occupancy group or a different use within the same group) falls under IEBC Chapter 10, Change of Occupancy, within the statewide-adopted 2024 International Existing Building Code — Utah Code § 15A-2-103(1)(i).; No standalone 'Change of Use' application form was found published by Cache County; a change-of-occupancy project is submitted through the same Building Permit Application channel used for all other permit types, describing the proposed 'Structure use type' (item 3 of that form).. If your project isn't listed, confirm with Cache County Building Division at (435) 755-1650 before starting work.

For a project that already has a building, addition, remodel, or tenant-improvement permit, the Certificate of Occupancy is issued at Final Inspection with no separate fee — the Building Division Fee Schedule (Ord. 2024-18) has no distinct Certificate-of-Occupancy line item. For a change of occupancy with no accompanying construction permit, the county's own fee schedule does not specify a figure; this is a genuine gap — confirm directly with Development Services, (435) 755-1650.

No standalone Change of Use application was found. Cache County's general Building Permit Application document covers this: item 3 captures the 'Structure use type' and item 7 states, quoting the form directly, 'A building or structure shall not be used or occupied in whole or part, and a change of occupancy of a building or structure or portion thereof shall not be made, until the building official has issued a certificate of occupancy therefor.'

A completed Cache County Public Works and Fire District Pre-Occupancy Checklist must be submitted at Final Inspection whenever it is required by a zoning clearance or encroachment permit, per that checklist's own instructions. Owners may not occupy or move into the structure before the Certificate of Occupancy is received, per the Building Permit Application document.
