Certificate of Occupancy

Also known as: CO, C of O, occupancy permit

Definition

A certificate of occupancy (CO) is an official document from a local government confirming that a building meets code and is safe and legal to occupy for a specific use. Businesses often need a valid CO before they can legally operate in a space.

A certificate of occupancy, or CO, is the local government’s sign-off that a building is safe and legal to occupy for a specific use. For a business, it is the difference between legally operating and getting shut down. A space zoned and certified for offices may not be valid for warehousing or light manufacturing.

Why it trips up small businesses

When you lease raw space or change how a building is used, you may need a new CO, which can mean inspections, a build-out, and delays before you can open. Pair that with industrial zoning rules and the move-in timeline gets complicated fast.

Frequently asked questions

Why do you need a certificate of occupancy?
A CO confirms a building is code-compliant and legally usable for its intended purpose. Without a valid CO for your use, a city can stop you from operating, deny permits, or fine you, so it matters before you sign or move in.
Who is responsible for the certificate of occupancy?
Responsibility varies. The building owner usually holds the base CO, but a change of use or a build-out can require a new one, and that often falls to the tenant. Always confirm the CO covers your intended use before committing.
