Retainage in Construction Contracts Explained
Retainage is money you earned but the payer holds back. The risk is not the percentage — it is how long it is held and what triggers release.

Overview
Retainage (or retention) is a percentage of each progress payment withheld until the work is complete, meant to give the payer security that the job will be finished and defects corrected.
The economics depend on the rate, what it applies to, and — most importantly — when it is released. Retainage held until final completion of the whole project can keep a sub’s profit tied up long after its scope is done.
Topics to check
Retainage is commonly five to ten percent of each payment. Check whether it applies to labor only or also to stored materials and equipment, and whether the rate steps down after the project reaches substantial completion or a percentage milestone.
Some state prompt-payment statutes cap retainage or require reduction after a milestone, especially on public work — but the limits are state-specific.
Release tied to a subcontractor’s own completion and acceptance is far better than release tied to final completion of the entire project. A sub that finishes early can otherwise wait many months — carrying the held retainage as unpaid profit — until the last trade is done.
Look for early-release or reduction mechanisms, separate retainage accounts (sometimes required on public jobs), and whether interest accrues on held amounts.
Negotiate a step-down (for example, retainage cut in half at substantial completion), release tied to your own scope completion, retainage on labor but not stored materials, and a clear punch-list-only holdback at the end rather than full retainage.
Preserve lien and bond rights for unpaid retainage; missing a lien or bond-claim deadline can forfeit the right to recover held money.

- Retainage is earned money withheld as completion security — commonly 5–10%.
- The biggest risk is release tied to whole-project completion, not your own scope.
- Some states cap retainage or require step-down, especially on public work.
- Negotiate step-down, early release on your scope, and no retainage on stored materials.
- Track lien and bond deadlines so unpaid retainage stays recoverable.

Guide confidence marker: Needs lawyer verification.
- Retainage caps, step-down requirements, escrow rules, and release timing are governed by state prompt-payment and lien statutes that vary widely.
- Confirm retainage and release rights with a construction attorney in the project’s state.

Frequently asked questions
How much retainage is normal?
Five to ten percent of each progress payment is common, sometimes stepping down after substantial completion. Some states cap retainage on public projects. The right number depends on the project and the state.
When should retainage be released?
Ideally when your scope is complete and accepted, not when the entire multi-trade project reaches final completion. Tying release to whole-project completion is a common red flag for subcontractors.
Is this legal advice?
No. This is general information for issue-spotting. Construction-contract enforceability — pay-if-paid, no-damages-for-delay, indemnity, lien and lien-waiver rules, retainage limits, and prompt-payment rights — varies by state and by whether the project is public or private, so confirm high-stakes points with a construction attorney licensed in the project’s state.
