What is a Certificate of Occupancy?
A Certificate of Use and Occupancy (CUO) establishes the approved legal use of a building or space. Previous certificates of occupancy issued for a building or space are superseded by the most recent legal use documented by the CUO. The CUO is required by the Ohio Building Code for every building to establish or to change its use as described by the code. Banks, other financial institutions, and government agencies often request proof of your legal occupancy by requesting a copy of the CUO.
