Certificate of Substantial Completion

In one sentence

A document certifying that construction is complete enough for the property to be used for its intended purpose.

The longer version

Substantial completion marks the point where a project is finished enough to occupy and operate, even if minor punch-list items remain. It triggers important milestones: final draws, the start of warranties, and conversion of construction to permanent financing.

Lenders confirm substantial completion through the architect's certificate and inspection before releasing final construction funds or converting a forward commitment.
