Change of Use / Certificate of Occupancy in Casper, Wyoming

Casper does not issue a standalone 'change of use' permit or a freestanding Certificate of Occupancy (C.O.) product separate from its building permit process — confirmed by direct review of the City's Permit Information page, Licenses and Permits page, and Permit Fee Schedule (eff. Feb 2, 2026), none of which list such a product. Per this file's own residential-building-permit and commercial-tenant-improvement-permit entries, 'Final / Certificate of Occupancy' is the final inspection step WITHIN the standard building permit process, not a separately purchasable permit. A genuine change in use or occupancy classification (without new construction) is governed by the 2024 International Existing Building Code (IEBC) — already listed in this file's codesAdopted — which contains dedicated Change of Occupancy provisions (IEBC Chapter 10) requiring compliance verification before the new use begins. Separately, registering a business at a new or different location is handled through the City's business-licensing process, though the specific 'change of location' mechanics were not independently confirmed.

Tips

  • Casper folds 'change of use' into its existing IEBC Chapter 10 (Change of Occupancy) building-code review rather than offering a separate change-of-use product — don't budget for a standalone C.O. fee that doesn't exist in the City's published fee schedule.
  • If a change of use doesn't require construction, the main obligations are likely a Planning/Zoning use-compatibility check (307-235-8241) and a business-license registration/update, not a Building Inspection Division permit — confirm with both offices, since this was not independently verified end-to-end.
  • Confirm zoning compatibility for the new use BEFORE signing a lease or starting a business-license application — Casper's zoning code (Title 17) determines whether the new use is even allowed in that district.
