Definition
Retainage (also called retention) is a portion of each construction progress payment that is withheld by the owner—or sometimes by the construction lender—until the project reaches substantial or final completion.
In simple terms: it is money held back to ensure the contractor finishes the job properly.
How Retainage Works
During construction, contractors submit periodic pay applications. The owner pays the approved amount minus a retainage percentage.
Example
- Contract value: $5,000,000
- Monthly approved draw: $500,000
- Retainage: 10%
Payment to contractor = $500,000 – $50,000 (retainage) = $450,000.
The $50,000 withheld is released later, typically after punch list completion.
Typical Retainage Percentages
- 5%–10% is common in private commercial projects
- Public projects may have statutory caps
- Some contracts reduce retainage after 50% completion
- Final retainage is often tied to lien waivers and closeout documents
Retainage and Subcontractors
General contractors often withhold retainage from subcontractors as well. This creates layered retention:
- Owner → General Contractor retainage
- General Contractor → Subcontractor retainage
Delays in upstream payments can affect subcontractor cash flow.
Retainage vs. Construction Holdback
- Retainage: Percentage withheld from each progress payment.
- Lender holdback: Funds not advanced until certain milestones are met.
In many projects, both mechanisms operate simultaneously.
Release of Retainage
Retainage is typically released when:
- Substantial completion is certified
- Punch list items are completed
- Certificate of Occupancy is issued (if required)
- Final lien waivers are delivered
- As-built drawings and warranties are submitted
Why Retainage Matters to Investors
- Risk mitigation: Ensures contractors complete final details.
- Leverage: Provides financial incentive for timely performance.
- Cash flow timing: Impacts final construction draw and equity deployment.
- Project closeout control: Ties documentation delivery to payment.
Common Pitfalls
- Releasing retainage before punch list completion.
- Failing to obtain final lien waivers before payment.
- Not defining clear retainage reduction milestones.
- Ignoring state-specific statutory requirements.
- Disputes over what qualifies as “substantial completion.â€
Investor & Developer Checklist
- Confirm retainage percentage in construction contract.
- Align retainage release with lender draw schedule.
- Track punch list status before approving release.
- Collect final lien waivers from all tiers.
- Document substantial completion certification.
Retainage in Construction Loans
Construction lenders often mirror retainage requirements and may:
- Withhold a percentage from each draw request
- Require third-party inspection reports
- Condition final funding on project closeout documentation
This creates dual oversight: contractual (owner) and financial (lender).
