Simple Certificate of Completion Template

Full Description

This certificate of completion for construction is a simple, editable document that confirms the work on a project has been finished in accordance with the contract documents. Use it at the end of the job, after the final walkthrough, to put completion in writing for the owner, consultants and contractor.

What is a certificate of completion in construction?

A certificate of completion is a short document signed at the end of a construction project, or a defined part of it, stating that the work has been completed as required by the contract. It is usually issued after an inspection where the owner, consultants and contractor walk the site together and agree the work is done. It marks the formal close of construction and is often linked to final payment, release of holdbacks and the start of warranty periods.

When to use it

• After the final walkthrough, once everyone agrees the work is complete.
• When the contractor needs written confirmation of completion to close out the contract.
• To complete a phase or separate package of work on a larger project.
• As part of the closeout documents handed to the owner.
• For small contractors who need a simple letter of completion for a client.

What’s included

This is a simple certificate of completion in an editable document format. It is written so the consultants can issue it to the contractor once the completion inspection is done, or so the contractor can submit it to the client when the construction work is finished. You can add your company details, project information and signature lines to suit your contract.

How to fill it out

1. Enter the project name, address and contract or job number.
2. Name the owner, contractor and consultants involved.
3. Describe the scope of work being certified as complete. Be specific if it covers only one phase.
4. Record the date of the completion inspection and the date of completion.
5. Note any agreed exceptions, such as minor deficiencies or seasonal work still to finish.
6. Have the authorized people from each party sign and date it.
7. Copy it to everyone involved and file it with your closeout documents.

Common mistakes to avoid

• Signing before the deficiency list is agreed. Attach or reference the list instead.
• Leaving the scope vague. Name the exact work, area or phase being certified.
• Assuming the certificate replaces permits or inspections required by your local authority.

Frequently asked questions

Who issues a certificate of completion in construction?

It depends on the contract. On many projects the architect, engineer or owner’s representative issues it after inspecting the work. On smaller jobs the contractor often prepares it and the owner signs to accept the work. Check your contract for who has the authority to certify completion.

What is a contractor certificate of completion?

A contractor certificate of completion is a document the contractor prepares to confirm they have finished the work in the contract. The owner or consultant then reviews and signs it to agree. It is commonly used on smaller projects and renovations where there is no formal consultant certification process.

Is a certificate of completion the same as a certificate of occupancy?

No. A certificate of completion is an agreement between the parties to the construction contract that the work is done. A certificate of occupancy, where required, is issued by the local building authority and confirms the building can be legally occupied. You may need both.

What happens if I don’t have a completion certificate?

Without written confirmation of completion, it can be harder to show when the work finished. That date often matters for final payment, holdback release and the start of warranty periods. A signed certificate gives all parties a clear, dated record to refer to if questions come up later.

What should a letter of completion include?

Include the project name and address, the parties, a clear description of the completed work, the inspection and completion dates, any agreed exceptions or open deficiencies, and signatures from each party. Keep the wording simple and match the names and scope to your contract documents.
