New commercial, industrial and multi-family developments in Clackamas County — including commercial and industrial building additions and tenant improvements — are required to have a Certificate of Occupancy in order for the structure to be occupied for its intended purpose and open to the general public.
Clackamas County issues both Temporary Certificates of Occupancy (TCO) and Permanent Certificates of Occupancy (CO). The following information reviews what these certificates mean and outlines the process to apply for and obtain a TCO and CO for your project.

The building permit specialist will update the status of your TCO application each time a division or agency signs off.
You are responsible for following up on the various required sign-offs. The permit specialist will not send you updates on your TCO as sign-offs occur.
When the last division or agency signs off on the TCO, the Building official will sign the TCO certificate and you will be contacted to let you know the TCO has been approved and issued.
The process for a CO is the same as for a TCO. The same agencies that signed off on the TCO must sign off on the CO once they are satisfied that their corrections or improvements have been completed.
