Change of Use / Certificate of Occupancy in Columbia Falls, Montana
Columbia Falls publishes no standalone change-of-use or certificate-of-occupancy application, checklist, or fee. The City's Building Permit Application's 'Class of Work' field is limited to New, Addition, Remodel, Repair, and Demolition and contains no Change of Use or Change of Occupancy option. Montana law (MCA 50-60-107) establishes the certificate-of-occupancy concept for buildings built under a certified local building code, and Columbia Falls has adopted the 2021 International Existing Building Code (IEBC), which contains the governing change-of-occupancy provisions, but no City-specific implementing process, fee, or timeline was found published.

When you need this permit
- No standalone 'change of use' or 'certificate of occupancy' permit application, checklist, or fee was found published by the City of Columbia Falls after exhaustive search of the DocumentCenter, Forms & Permits page, and Permits & Applications page
- The City's Building Permit Application's 'Class of Work' field is limited to NEW, ADDITION, REMODEL, REPAIR, and DEMOLITION (confirmed directly on the form, DocumentCenter/View/244) and does not include a distinct Change of Use or Change of Occupancy option; a use or occupancy change involving construction work is understood to be submitted as a Remodel under the general Building Permit Application, though this is not stated explicitly by the City
- Columbia Falls has adopted the 2021 International Existing Building Code (IEBC), which contains the governing change-of-occupancy provisions (egress, fire-resistance, and other requirements triggered by a change in a building's occupancy classification), per this record's codesAdopted entries
- Mont. Code Ann. 50-60-107 provides that 'a certificate of occupancy for a building constructed in accordance with the provisions of the state building code or county, city, or town building code must certify that the building conforms to the requirements of the building regulations applicable to it,' but does not itself specify a City of Columbia Falls issuance process, fee, or timeline
- Confirm with the Building Clerk, (406) 892-4432, whether a change in a building's use or occupancy classification requires a Remodel-classified Building Permit and/or triggers a distinct sign-off before occupancy, since no dedicated City document addresses this directly
