What Is Certificate of Occupancy in Construction?
Definition
A certificate of occupancy (CO) is a document issued by the local building department that certifies a building has been inspected and meets all applicable building codes, zoning regulations, and safety requirements for its intended use. No building can be legally occupied without a valid certificate of occupancy.
The certificate of occupancy is the final regulatory approval required before a building can be used. To obtain a CO, the building must pass all required inspections, including structural, electrical, plumbing, mechanical, fire protection, and accessibility. The building official conducts a final inspection to verify that the constructed building matches the approved plans and meets all code requirements.
The CO specifies the type of occupancy the building is approved for, such as business, assembly, residential, or mixed use. It also lists the maximum occupant load for assembly spaces and any specific conditions or restrictions. A building cannot be used for a purpose different from what the CO specifies without applying for a change of occupancy.
Temporary certificates of occupancy (TCO) may be issued when the building is substantially complete and safe for occupancy but minor items remain to be finished. A TCO has an expiration date by which all remaining work must be completed and a final CO issued. Failure to obtain the final CO before the TCO expires can result in the building being shut down.
Why It Matters
A certificate of occupancy is a legal requirement. Occupying a building without one violates building codes and can result in fines, legal action, and insurance complications. For the project owner, the CO is the milestone that allows tenants to move in and revenue to begin flowing. For the contractor, it is often tied to final payment milestones in the contract.
How HomeFloorPlan Helps
HomeFloorPlan helps teams prepare for final inspection by tracking all open items that could prevent a CO from being issued. The platform visual punch list makes it easy to verify that all deficiencies have been addressed before calling for the final inspection, reducing the risk of failed inspections and delayed occupancy.
Frequently Asked Questions
What is the difference between a certificate of occupancy and a temporary certificate of occupancy?
A certificate of occupancy is a permanent approval to occupy the building. A temporary certificate of occupancy (TCO) allows occupancy for a limited time while minor work items are completed. TCOs have expiration dates and must be converted to a final CO when all work is finished.
Who issues a certificate of occupancy?
The local building department or building official issues the certificate of occupancy after conducting a final inspection and confirming that the building meets all applicable codes. The contractor or owner typically requests the final inspection when the building is ready.
