Certificate of Occupancy Policy

After a project passes Final Inspection, a Certificate of Occupancy (C of O) is issued. This allows the business to begin operation or a homeowner to move in. The International Building Code, Section 111, requires specific information to be included on the C of O. This information includes, among other things, the project address and the owner’s
name. The owner listed on the C of O is the owner at the time the construction permit is issued. If ownership of a property changes during construction, a Change of Record Affidavit is required in order to change the permit and the resulting C of O. Once the C of O has been issued, no changes will be allowed. The C of O will stay with the property based on the property address indefinitely, even if there is a change in ownership or a tenant change. If the
current use of the building or tenant space changes, a new C of O must be established.

When all required inspections have passed and the information is documented, a certificate of occupancy will be automatically generated if the project requires one. A green tag signifying compliance with certain code requirements will be given to projects that do not require a new certificate of occupancy.

completion, or portion thereof, a Temporary Certificate of Occupancy may be issued. This includes such uses as
