Certificate of Completion
A document confirming that a construction project has been completed according to the plans, permits, and applicable codes. Issued by the Authority Having Jurisdiction for permitted work and often required before final payment, occupancy, or transfer of property.
A certificate of completion is a document from the local Authority Having Jurisdiction confirming that a construction project has been completed according to the approved plans, permits, and applicable codes. It is the official AHJ sign-off that the work is done correctly.
When Certificates Apply
Any permitted project generates a certificate at completion. The certificate may be called a certificate of completion, a certificate of occupancy, or use different terminology depending on the AHJ and the project type. New construction and major renovations requiring occupancy typically receive certificates of occupancy. Smaller renovations and restoration work receive certificates of completion. Both serve the same fundamental purpose: documenting regulatory sign-off.
What It Takes to Get One
The path to certificate typically runs through: permit issuance, completion of all work per the permit scope, passing of all scheduled inspections (including final inspection), resolution of any outstanding items, and submission of any required final documentation. The AHJ reviews and issues the certificate once all conditions are satisfied.
Why It Matters at Closeout
The certificate is a key part of project closeout. It protects the property owner by documenting that the work was legal and compliant. It supports future transactions — buyers and lenders often require certificates to confirm past work was permitted. For insurance restoration, the certificate documents that repair work was completed properly, supporting the claim and avoiding future compliance issues. Contractors who close out cleanly deliver the certificate as part of the final handoff package.
Frequently asked questions
Certificates of occupancy (CO) are typically issued for new buildings and major renovations, authorizing the building for occupancy. Certificates of completion (CoC) are often issued for projects that do not require a full CO — like renovations to existing occupied structures or additions without changes to the primary use. Terminology and use vary by AHJ.
The local Authority Having Jurisdiction — usually the city or county building department. The certificate is issued after final inspection confirms all work meets code and matches the approved permit. Projects without permits do not receive a certificate, which can cause complications at future sale.
For restoration claims involving permitted work, yes, typically. The certificate documents that the work was completed to code, supporting the claim payment and protecting the owner from future compliance issues. Contractors closing out restoration jobs should obtain and deliver the certificate as part of closeout.
