# Certificate of Occupancy vs. Permit

Also known as: CO vs permit

A permit authorizes construction to begin; a Certificate of Occupancy confirms it was completed correctly and the building is legal to occupy.

A building permit and a Certificate of Occupancy (CO) are two distinct milestones in the construction lifecycle. The permit is issued before work begins and authorizes the project; it does not certify that the work was done correctly. The CO is issued after all required inspections pass and certifies that the completed structure is safe, code-compliant, and legally ready for occupancy. A project can have an open permit with no CO for months or years — a sign of stalled construction. Some jurisdictions issue a Temporary Certificate of Occupancy (TCO) when a building is substantially complete but minor items remain.

## Why it matters for contractors

Monitoring the gap between permit issuance and CO issuance reveals stalled projects, phased construction, and active job sites where subcontractors are still being engaged.
