Substantial Completion: What Is It and Why Is it Important?

Substantial completion is a key milestone in any construction project. It signals that the project is essentially complete and that the owner can take possession of the property. This milestone is important for a number of reasons, including:

It triggers the final payment to the contractor

It marks the point at which the warranty period begins

It allows the owner to start using or generating revenue from the property

To achieve substantial completion, all major work must be completed and all punch list items must be addressed. Once these milestones are met, the contractor will submit a certificate of substantial completion to the owner. This document signals the end of the construction process and sets in motion the final steps in the project.

If you’re planning a construction project, it’s important to understand the concept of substantial completion and what it means for your project. Working with a knowledgeable contractor can help ensure that your project stays on track and meets all the necessary milestones.
