Change of Use / Change of Occupancy Permit
VerifiedRequired whenever a building's use or occupancy classification changes in Westminster, governed by the City's adopted 2021 International Existing Building Code (WMC 11-9-1(9)). The Building Division must confirm a proposed occupancy type is allowed in the existing building, and the Fire Department separately reviews the change for fire code compliance. If no structural changes or improvements are made to the site, an Official Development Plan (ODP) is not required (WMC 11-5-5(B)(3)), but Building Division and Fire Department review still applies.
