What is a punch list in construction?

A punch list (snag list) is a document listing minor incomplete or defective work items identified during final inspection before project closeout. It is prepared by architect, owner, or construction manager during walkthrough of completed work. Items typically include cosmetic defects, missing hardware, incomplete finishes, and minor operational issues. Contractor corrects punch list items, then requests final inspection. Completion of punch list is required for substantial completion certificate and final payment release.
