Subcontractor retention release is the payment of retainage funds back to the subcontractor after their work is complete. The timing, process, and legal requirements for release vary dramatically across states. A release that is timely in Georgia may trigger penalties in Florida. A process that works on private projects may violate public project statutes.

This state guide maps the retention release requirements that matter most to GCs and subcontractors. It covers release triggers, notice periods, interest penalties, and dispute resolution options in the states with the most construction activity.

Release Triggers: What Starts the Clock

Retention release timing depends on which event triggers the release obligation. States and contracts define four primary triggers:

Trigger Type	How It Works	States Using This Trigger
Sub's scope completion	Clock starts when the sub's work is accepted	FL, CA, OR, MN, IL
Project substantial completion	Clock starts when the entire project reaches substantial completion	NY, TX, GA, most contract default
Final acceptance/completion	Clock starts when the owner accepts the completed project	Federal (FAR), OH, MD
Milestone-based	Partial release tied to specific sub milestones	Contractual only, no state mandate

The trigger matters because it determines how long the sub waits. A mechanical sub who finishes in month 6 of a 14-month project waits 8+ months for retention if the trigger is project substantial completion. Under a sub-scope-completion trigger, they wait 30-60 days.

State-by-State Release Requirements

Florida

Release trigger: Completion and acceptance of the sub's portion of work.

Deadline: Owner must release retainage to GC within 30 days. GC must pay sub within 10 days of receiving retainage from owner. Total maximum: 40 days from sub's completion.

Interest penalty: 1% per month on late retention payments. Plus prevailing party attorney fees in any action to recover.

Notice requirement: Sub should provide written notice of completion and request for retainage release. No specific statutory form required.

Dispute resolution: If the GC disputes the sub's completion, they must provide written notice of specific deficiencies within the contractual period. Vague objections do not stop the release clock.

California

Release trigger: Completion and acceptance of the sub's work.

Deadline: 30 days from completion of sub's work on private projects. Public projects follow the specific agency's procedures.

Interest penalty: 2% per month on wrongfully withheld retention. This is one of the steepest penalties in the country.

Special rules: Subs may substitute securities (government bonds, bank CDs) in lieu of cash retention. The GC must accept the substitution if the securities meet statutory requirements.

Escrow: Not mandatory, but securities substitution effectively creates an escrow arrangement.

Texas

Release trigger: Government contracts: acceptance of the sub's work by the government entity. Private contracts: per contract terms.

Deadline: Government contracts: 30 days after acceptance. Private contracts: per contract (prompt-payment act applies to progress payments but retainage treatment varies).

Interest penalty: Government contracts: 1.5% per month on late payments. Private contracts: 1.5% per month under the prompt-payment act if the GC has received payment from the owner.

Special rules: On government contracts exceeding $400,000, retainage may not exceed 5% without written justification. The government entity may reduce retainage below 5% at its discretion.

New York

Release trigger: Per contract terms; typically tied to project substantial completion.

Deadline: Per contract, but the Interest on State Contracts Act and Prompt Payment Act apply to government work.

Interest penalty: Government contracts: interest at the rate specified in the contract or the statutory rate (currently the overpayment rate established by the IRS). Private contracts: per contract terms.

Special rules: On public projects, retainage must be deposited in an interest-bearing account if the sub requests it (for prime contracts over a threshold amount). The Wicks Law applies to public projects over $500K in NYC and $3M elsewhere, affecting how retainage flows to trade primes.

Illinois

Release trigger: Completion of the sub's work.

Deadline: Private projects: 60 days from sub's work acceptance. Public projects: 60 days from final acceptance of the sub's work.

Interest penalty: Private: 2% per month. Public: interest at the rate paid by the State Treasurer on warrants, plus attorney fees.

Special rules: On public contracts, the GC must include retainage release provisions that comply with the State Prompt Payment Act. The contractor cannot withhold retention in excess of the percentage the owner withholds from the GC.

Ohio

Release trigger: Completion of the sub's scope of work and approval by the owner or engineer.

Deadline: Public projects: within 30 days of final acceptance. Private projects: per contract terms.

Interest penalty: Public projects: interest at 18% per annum on late retention payments. This is among the highest in the country.

Escrow: Public projects: retainage must be deposited in an escrow account and the sub receives the interest earned. This is mandatory, not optional.

Georgia

Release trigger: Per contract terms. No specific statutory trigger for retainage.

Deadline: Georgia's prompt-payment statute applies to progress payments. Retainage release follows contract terms.

Interest penalty: 1% per month on amounts not paid within 10 days of the contractual due date, if the GC has received payment from the owner.

Special rules: Georgia does not cap retainage percentages or mandate escrow. Contract terms control entirely. This makes Georgia one of the most GC-friendly states for retainage practices.

Release Process: What Documentation Is Required

Regardless of state, the retention release process typically requires these documents from the subcontractor:

1. Final pay application. Shows all work complete, all previous payments received, and the retention balance requested for release.

2. Certificate of substantial completion. Signed by the architect or GC confirming the sub's scope is substantially complete. AIA G704 is the standard form.

3. Punch list completion sign-off. Written confirmation that all punch list items for the sub's scope have been completed and accepted.

4. Final lien waiver. Unconditional waiver covering all work performed and all payments received, including the retention being released. Most states have statutory waiver forms.

5. Sub-tier lien waivers. Waivers from the sub's suppliers and sub-subcontractors for all materials and labor provided.

6. Warranty documentation. Written warranties for the sub's work per the contract requirements, plus manufacturer warranties for installed products.

7. As-built documents. Marked-up drawings showing the actual installed conditions for the sub's scope.

8. Closeout documents. O&M manuals, attic stock, spare parts, testing reports, and any other documents required by the subcontract.

Interest Calculation on Late Retention

When a GC misses the retention release deadline, interest accrues. The calculation method varies by state:

State	Interest Rate	Calculation Method	Compounding
California	2% per month	Simple interest	No
Florida	1% per month	Simple interest	No
Illinois	2% per month	Simple interest	No
Ohio (public)	18% per annum	Simple interest	No
Texas (gov't)	1.5% per month	Simple interest	No
Minnesota	1.5% per month	Simple interest	No
New York	IRS overpayment rate	Compounding allowed	Varies

Example calculation: $50,000 retention, 90 days late in California.

$50,000 x 2% per month x 3 months = $3,000 in penalties
Plus attorney fees if the sub had to send a demand letter or file suit

Dispute Resolution When Retention Is Contested

When the GC withholds retention citing deficiencies and the sub disagrees, resolution depends on the contract and state law.

Contractual remedies:

Mediation (most AIA and ConsensusDocs contracts require mediation first)
Arbitration (if the contract includes an arbitration clause)
Litigation (if the contract does not mandate alternative dispute resolution)

Statutory remedies:

Mechanic's lien (the sub files a lien for the unpaid retention amount)
Payment bond claim (on bonded projects, the sub claims against the GC's bond)
Prompt-payment act claim (the sub sues for the retention plus statutory penalties)
Stop-work notice (in states allowing suspension of work for non-payment)

Practical resolution steps:

Sub sends written demand for retention release with supporting documentation
GC responds within contractual period with specific deficiency items and costs
Parties attempt to resolve through project-level negotiation
If unresolved, escalate to mediation per contract terms
If mediation fails, proceed to arbitration or litigation

The average retention dispute takes 4-8 months to resolve through mediation and 12-24 months through litigation. Legal costs for the GC average $15,000-$35,000 per dispute.

Retention Release Tracking Across Multiple States

Multi-state GCs face the highest compliance risk because each project follows different rules. A tracking system must handle:

Different release triggers per state and project type
Different deadline calculations based on the trigger date
Different interest rates and penalty provisions
Different documentation requirements
Different escrow obligations

Manual tracking across 15+ projects in 5+ states is where errors occur. The most common error: applying one state's deadline to a project in a different state. The second most common: failing to start the release clock when the sub's scope is complete because the PM was tracking project completion, not sub completion.

Frequently Asked Questions

Can a GC release retention to some subs but not others on the same project?

Yes. Each subcontract is a separate agreement with independent retention terms. The GC can and should release retention to subs who have completed their work, even if other subs are still working. Holding all retention until the last sub finishes penalizes early-completing subs without legal justification.

What if the owner has not released retention to the GC?

This depends on whether the subcontract contains a pay-if-paid or pay-when-paid clause. In states that enforce pay-if-paid clauses, the GC's obligation to release sub retention may be conditioned on receiving retention from the owner. In states that void pay-if-paid clauses (New York, California, and others), the GC must release sub retention per the contractual or statutory deadline regardless of owner payment.

Is there a statute of limitations on retention claims?

Yes. The statute of limitations for a breach of contract claim (which includes wrongful retention withholding) varies by state, typically 3-6 years from the date the retention was due. Mechanic's lien filing deadlines are much shorter, typically 60-120 days from the sub's last day of work. Subs who miss the lien deadline may still pursue a contract claim.

Can the sub charge the GC for the cost of financing withheld retention?

Not typically under standard contract terms. However, some specialty subcontracts include a "cost of money" provision that allows the sub to bill the GC for the financing cost of retained funds held beyond the contractual release date. This is more common in negotiated contracts with large mechanical and electrical subs.

Does the GC need to provide a reason for withholding retention?

Yes, in virtually all circumstances. A blanket withholding of retention without itemized deficiencies is legally vulnerable. The GC must identify specific incomplete or defective work items, provide written notice per the contract terms, and withhold only the amount reasonably related to the identified deficiencies. Withholding the full retention for a $2,000 punch list item on a $500,000 subcontract is disproportionate and courts will not uphold it.

What is a conditional vs. unconditional retention release waiver?

A conditional waiver is effective only when the sub receives the retention payment. If the check bounces, the waiver is void. An unconditional waiver is effective immediately upon signing, regardless of whether payment has been received. Subs should provide conditional waivers with the retention request and unconditional waivers only after funds have cleared.

Release deadlines, interest calculations, and documentation requirements differ in every state. SubcontractorAudit's pay application audit tracks retention release triggers by state, calculates penalties for late release, and generates change order-adjusted retention balances automatically.
