Retainage: what is held back and when it is released

Retainage is part of a payment held until the contract’s release conditions are met. Check the percentage, the amounts it applies to and the release deadline before bidding. It can leave cash tied up after your work is finished, so include that wait in your funding plan.

What gets withheld, and by whom

Retainage can apply at both levels: the owner’s payments to the GC and the GC’s payments to a sub. Your subcontract and applicable law determine what may be withheld from you.

Three things about your own withholding are worth reading closely in the subcontract:

• Compare your percentage with the owner’s. Check both contracts and any statutory cap. For covered New York construction contracts, GBS 756-c limits retainage and restricts downstream withholding. Do not assume the same rule covers every state or project.
• Approved change orders are usually retainage-bearing too. A $30,000 change order on a 10% job means another $3,000 waits with the rest.
• Stored materials may or may not be included. Some subcontracts hold retainage on labor only, some on the full billed amount including material still in a warehouse.

Retainage is also not a backcharge. A withholding for defective work comes off one pay application with a reason attached. Retainage follows the agreed basis and applicable limits; it does not necessarily apply to every item.

The percentage is a contract term, not a standard

The examples here use 5% and 10% to explain the arithmetic. They are not a survey of market rates or permission to withhold those amounts. The number that governs your job is the one printed in your subcontract — unless a statute in your state overrides it, which is a real possibility and worth checking.

• Public work can be capped by statute. The applicable public-contracting or prompt-payment rule is the source.
• Federal work has its own contract clauses. FAR 52.232-27 addresses construction payment and subcontract payment provisions. Read the clauses incorporated into your contract.
• Private commercial work can also be regulated. Check the project state rather than assuming private means unregulated.

Ask a construction attorney in your state before you assume a cap protects you.

Example: 10% retainage on a $240,000 job

Fictional example: a mechanical sub has a $240,000 scope, eight months of progress billing and an assumed 10% retainage:

At an 8% net margin, the profit on that job is $19,200. The retainage is $24,000. Every dollar of profit and then some is sitting in the owner's account on the day you finish. That is the number to look at, not the percentage: at single-digit margins, 10% retainage is not a 10% problem, it is all of the profit held for an unknown number of months.

Why the money sits longer than your scope did

Release may depend on substantial completion of the whole project rather than your scope alone; check the contract and any right to earlier release. Site work, underground utilities, concrete and framing finish early and then wait on everyone downstream. An excavation sub who wrapped in month two of a fourteen-month build can be holding retainage for a year.

Release can depend on other trades' punch lists, inspection, a certificate of occupancy, or architect sign-off. Lien deadlines may run before retainage is payable and can have a separate rule, so get the actual state deadlines and diary them.

The closeout package that unlocks it

Release can require both completion conditions and a documented request. Check the actual contract list and statutory deadline. Get your part of that list from the project manager in the first month, not the last:

• Punch list items signed off in writing
• As-built drawings for your scope
• Operation and maintenance manuals and warranty documents
• Final inspection or authority sign-off where required
• Certified payroll through the last day, on prevailing-wage jobs
• Final lien waivers from you, your suppliers and any lower-tier subs you used
• Consent of surety, where the bond requires it

The lien waiver is central. A conditional waiver can be tied to payment while an unconditional form can take effect on signature. Do not sign a final unconditional waiver before confirming cleared funds and the project-state form.

If the file is complete and the money still does not move, your state's prompt payment act may set a deadline for release after substantial completion, and may separately require a GC to pass retainage down within a set period of receiving it. Deadlines and remedies vary widely, so check the statute for your state and for the job type.

What to negotiate before you sign

Subject to legal requirements, ask whether the GC will agree to any of these terms:

• Early release for a completed scope. Written into the subcontract: retainage on your work releases when your scope is accepted, not when the project is.
• A step-down. A higher percentage early, then less after defined completion.
• Labor only. No retainage on stored or installed material, which for equipment-heavy trades is most of the contract value.
• A cap in dollars. 10% of each payment until the held amount reaches an agreed figure, then nothing further.
• A retainage bond or letter of credit in lieu of cash. Ask whether it is available and what it costs.

All of it lands better in the bid conversation than in month five, when you are asking for a favor rather than negotiating a term.

Carrying it in your price

If you cannot negotiate the terms, price them. Work out the peak amount held on the jobs you actually bid, decide how you will fund that gap, and include the financing cost in your price calculation.

On the $240,000 job above, $24,000 carried for six months costs you whatever your line of credit charges — at an illustrative 10% annual simple interest rate, that is $1,200, about 6% of the job's profit spent on waiting. Use your own rate, not that one. Two of those overlapping and you are funding $48,000 of someone else's guarantee out of a business that does not have $48,000 spare.

Save the calculated selling rate in your DoneQuote service catalog and review it on the quote before sending. Carry the approved breakdown into the GC’s schedule of values and track applications, payments and retained balances in your billing records.

Retainage is not a reason to skip commercial work. It is a reason to know, before you sign, exactly how much of your profit the job will hold and for how long.
