Retainage and the Fight Over Final Payment
Every construction dispute is really an argument about the last five percent, because by the time it starts, the last five percent is all the leverage anyone has left.
What this report covers
- Retainage is withheld from each progress payment, not saved up from the last one.
- Many states cap residential retainage by statute and require release within a set period after completion.
- Substantial completion — usable for its intended purpose — is the usual trigger, not final perfection.
- Prompt payment statutes often add interest and attorney fees to a wrongfully withheld release.
- A retainage dispute and a lien claim run on different clocks, and the lien deadline is the unforgiving one.
Retainage looks like an accounting detail and functions as the entire enforcement mechanism of a construction contract. Every other protection — the schedule, the specification, the warranty — depends on the contractor still wanting something the owner has.
What retainage is, precisely
Retainage is a percentage withheld from each progress payment as the work proceeds, accumulating into a sum released at completion. Two things follow from that definition and both are frequently misunderstood.
First, it is withheld along the way. An owner who pays every invoice in full and then declines to pay the final one has not retained anything; they have stopped paying, which is a different legal position and a much weaker one.
Second, it belongs to the contractor. It is earned money held as security for completion, not a discount, and it is released when the condition it secures has been satisfied.
Several states cap retainage on residential work by statute, commonly at five percent, and some require reduction once the job is substantially complete. A contract term above the cap is unenforceable to that extent, and a contractor who accepted it is generally still entitled to the statutory position.
The trigger: substantial completion
The release condition is normally substantial completion, not perfection. A project is substantially complete when it can be used for its intended purpose, even though minor items remain. For a house that usually means the certificate has issued and the family can move in.
Marking it matters because several clocks start from it:
- The period for releasing retainage, or for reducing it.
- The warranty period on the work.
- In many states, the window for filing a lien claim.
- The transfer of risk and of insurance responsibility for the finished work.
Record the date in writing when it happens. Reconstructing it a year later from photographs and text messages is a common and avoidable exercise.
Punch lists and proportionate withholding
Once a project is substantially complete, the remaining items are documented on a punch list. The rule that governs the money at this point is proportionality: the owner may retain an amount reasonably related to finishing the list — commonly one and a half to two times the estimated cost — and must release the rest.
| Situation | Defensible | Not defensible |
|---|---|---|
| Minor snagging remains | Hold twice the estimated cost | Hold the whole balance |
| Work is defective | Hold the cost to cure, with an estimate | Hold indefinitely without notice |
| Permit not closed | Hold pending the final inspection | Hold after the certificate issues |
| Documents outstanding | Hold pending waivers and warranties | Invent new conditions late |
A good punch list is specific, dated, agreed in writing, and priced. A list that grows each time the contractor completes an item is evidence of bad faith, and it is the fastest way for an owner to lose a case they would otherwise have won.
Prompt payment statutes
Most states have prompt payment legislation covering private construction as well as public work. The provisions that matter to a homeowner:
- A deadline for releasing retainage after the triggering event.
- Interest running on late payment, often at a statutory rate well above commercial rates.
- A requirement to give written notice of the reason for withholding, within a set period.
- Fee-shifting to the prevailing party in a dispute about withheld payment.
That last provision changes the economics. An owner withholding twelve thousand dollars without written notice of the reason can find themselves paying the sum, interest, and the contractor's legal fees — considerably more than the defects were worth. The protective step is trivial: state the reason in writing, with the amount attributable to each item, within the statutory window.
The lien clock runs regardless
A contractor who is not paid does not need to sue to create leverage. They record a lien, and the deadline for doing so is short and independent of any negotiation. An owner who believes a dispute is being worked out amicably can find a lien recorded against the property because the contractor's filing period was about to expire.
Two consequences follow. For the owner: expect a lien in any genuine dispute, and understand that it is a preservation step rather than an escalation. For the contractor: diary the deadline separately from the negotiation, because the notice and filing periods are unforgiving and a missed one leaves only a contract claim.
Closing out so the last payment is uncontroversial
The final payment goes smoothly when the conditions were defined at the start. A workable closeout package: unconditional lien waivers from the contractor and everyone who served notice, a copy of the closed permit and the certificate of occupancy, warranties and manuals, as-built drawings where relevant, and a signed punch list showing every item completed.
Where allowances were used, the reconciliation should already be agreed rather than arriving with the final invoice — an unreconciled allowance is the most common reason a final payment is contested at all.

Questions readers ask
How much can I hold back?
Whatever the contract says, subject to any statutory cap in your state. Five to ten percent of each progress payment is the common range, and several states cap residential retainage at five percent or require it to be reduced once the job is substantially complete. A retainage figure that appears only at the end, rather than being withheld along the way, is not retainage — it is a refusal to pay, and it is treated differently.
When does the contractor get it?
Usually within a defined period after substantial completion or after final acceptance, whichever the contract and the state statute specify. Prompt payment statutes commonly set fifteen to thirty days and add interest for late release. Conditions such as delivery of lien waivers, warranties, manuals and a closed permit are legitimate preconditions if the contract states them.
Can I hold everything back over a punch list?
Rarely, and doing so is where owners lose. Once a project is substantially complete, most statutes and most contracts allow retention of an amount reasonably related to the cost of finishing the outstanding items — commonly one and a half to two times that estimate — not the whole balance. Holding the entire final payment over a list of minor items turns the owner into the party in breach.
