Retainage
A percentage of each progress payment withheld by the owner until final completion and inspection. Common retainage is 5 to 10 percent. The held-back funds are released at project closeout, giving the owner financial leverage to ensure punch-list items are completed.
Retainage is a percentage of each progress payment that the owner withholds until final completion of the project. It is a cash flow management tool and, more importantly, a performance incentive built into the payment structure.
Why Retainage Exists
Without retainage, a contractor could collect nearly all of the contract value during construction, leaving little incentive to return and complete punch-list items, address warranty issues, or ensure final closeout is smooth. Retainage creates a meaningful pot of money (often 10 percent of contract value) that only gets released when the project is genuinely finished, keeping the contractor motivated to complete every last detail.
How Much Is Typical
5 to 10 percent is standard across most residential and commercial construction. Some states limit retainage by statute, especially on public projects or residential work. The applicable contract, combined with local law, determines the exact percentage and conditions.
Release Conditions
Retainage is typically released at final completion, after the punch list is resolved, final lien waivers are submitted, and in some cases, a certificate of occupancy is issued. The release conditions are spelled out in the contract. Contractors should pay attention to these conditions because overlooked items (a missing lien waiver, an unsigned final walkthrough, a remaining punch item) can delay release even after the bulk of the work is complete.
Frequently asked questions
5 to 10 percent is the typical range in residential and commercial construction, though this varies by contract and jurisdiction. Some states limit the retainage percentage or the duration for which it can be held on public or residential projects. The specific contract should always be consulted.
Typically at final completion and after punch-list items are resolved. Some contracts release part of the retainage at substantial completion and the balance after the punch list is finished. The release is often tied to final lien waivers, certificates of occupancy, and in some cases warranty commencement.
Sometimes. Many contracts allow reducing retainage at specific milestones if the project is proceeding well. This rewards strong performance and improves the contractor's cash flow. Others keep retainage at a consistent percentage throughout the project.
