Private Construction Contract Reform: Retainage Cap Reinforced in New York
In late 2025, New York further clarified and strengthened statutory protections governing retainage in private construction contracts. On December 19, 2025, Governor Kathy Hochul signed A.5405/S.5655 into law, amending the New York General Business Law to make clear that contractual provisions requiring retainage above five percent are void and unenforceable. This legislation builds directly on the 2023 amendments to New York’s Prompt Payment Act and reflects the Legislature’s continued effort to promote prompt and predictable payment practices in private construction projects.
Background on the Prompt Payment Act and Retainage Limits
In November 2023, New York enacted significant amendments to the Prompt Payment Act, codified primarily in General Business Law §§ 756-a and 756-c. Among other reforms, the statute imposed a five percent cap on retainage in private construction contracts with a total value of $150,000 or more. The law was intended to address long-standing concerns that excessive retainage unfairly shifted financial risk to contractors and subcontractors and delayed payment well beyond the completion of meaningful work.
Under the 2023 amendments, retainage in covered private construction contracts could not exceed five percent of the total contract sum, and a subcontractor’s retainage could not exceed the percentage withheld from the prime contractor. The amendments also required release of retainage within thirty days after final approval of the work and allowed contractors to submit a final invoice upon substantial completion, as defined by the contract, rather than waiting until full project closeout. Despite these changes, some parties continued to draft contracts that attempted to require retainage in excess of the statutory cap, creating uncertainty as to whether such provisions were enforceable.
The 2025 Amendment Clarifying Enforceability
The 2025 legislation directly addressed these attempts to contract around the statute. By amending General Business Law § 757, the Legislature expressly provided that any provision in a covered private construction contract requiring retainage above five percent of the contract sum is void and unenforceable as a matter of law. The amendment applies to contracts entered into on or after November 17, 2023, the effective date of the original Prompt Payment Act reforms. As a result, parties cannot rely on negotiated contract language to justify higher retainage on newer contracts, even if such provisions were agreed to by all parties at the time of execution. This clarification reinforces that the five percent retainage cap is mandatory rather than a default rule and eliminates arguments that sophisticated parties may opt out of the statutory framework.
Practical Implications for Owners, Contractors, and Subcontractors
For owners and developers, the 2025 amendment underscores the importance of reviewing and updating standard form agreements, procurement documents, and project manuals to ensure that retainage provisions comply with current law. Contract language that requires or permits retainage above five percent now carries a clear risk of being deemed unenforceable.
General contractors should similarly review prime contracts and subcontract forms to confirm that retainage provisions align with the statutory cap and mirror the retainage actually withheld by the owner. Internal accounting and project administration practices should also be reviewed to ensure retainage is released in accordance with the statutory timelines.
Subcontractors and trade contractors should be aware that retainage withheld in excess of five percent on covered private projects may violate the General Business Law. The 2025 amendment strengthens the statutory basis for challenging excessive retainage and may affect how payment disputes are resolved on projects subject to the Prompt Payment Act.
Key Takeaways
New York’s 2025 legislation reinforces the State’s policy favoring prompt payment and limits on retainage in private construction contracts. By expressly voiding contractual provisions that exceed the statutory five percent cap, the Legislature has reduced uncertainty and curtailed attempts to circumvent the Prompt Payment Act through contract drafting.
Parties involved in private construction projects in New York should carefully review existing contract forms and payment practices to ensure compliance with the reinforced retainage regime. Proactive review and revision of contract documents can help avoid disputes, payment delays, and potential exposure under the General Business Law. If you have questions about how these changes may affect your construction contracts or ongoing projects, you should consult with experienced construction counsel to evaluate your specific circumstances.
