Retainage

Retainage (also called retention) is a standard practice in construction where a percentage of each progress payment - typically 5% to 10% - is withheld until the project reaches substantial completion or final completion. The withheld funds serve as financial leverage to ensure contractors and subcontractors complete their work to specification.

For general contractors, retainage management is a two-sided obligation. GCs must track retainage withheld from their subcontractors while also managing retainage withheld from them by the project owner. Mismanaging retainage can create cash flow issues for subcontractors and lead to lien filings, payment disputes, or project delays.

Retainage requirements vary by state, with some jurisdictions capping the allowable percentage or requiring retainage to be held in escrow accounts. Federal projects under the Miller Act and many state prevailing wage projects have specific retainage rules that GCs must follow.

When evaluating retainage in a construction compliance context, GCs should consider the contract terms, state statutory limits, and the impact on subcontractor cash flow. Retainage should be released promptly upon substantial completion to maintain good subcontractor relationships and avoid lien exposure.

In the construction industry, retainage directly affects subcontractor cash flow and project risk. General contractors who implement systematic tracking of retainage obligations - including release triggers, escrow requirements, and state-specific caps - report fewer payment disputes and stronger subcontractor relationships. Automated pay application systems can track retainage across all active projects and flag when release conditions are met.
