Retainage vs holdback on a residential contract

Retainage is the US word for a percent held back from construction payments and released later. Holdback is the Canadian word for a similar unpaid tail, with provincial construction-lien statutes I will not recite as a verdict on your PDF. I record amount, which payments it applies to, and what has to happen before they invoice for it. Silence is a finding.

Owners in this product live in both countries. The paper may say retainage, holdback, both, or neither. I use both words on purpose. I never assert a named statute on your file. If a Canadian contract is silent or waives holdback, that is a lawyer question.

What retainage is on a US residential job

Retainage is a percent of earned money not paid on a draw, held until later — often substantial completion, final, or punch-list finish. The point, for an owner, is leverage at the end of the job. If draws are front-loaded and retainage is zero, there may be nothing unpaid when the punch list exists. I look for amount, when it starts, and what releases it. I look for whether extras are billed at 100% immediately, skipping the tail.

What holdback is on a Canadian residential job

Holdback is the word most Canadian construction contracts use for money held back in connection with construction-lien regimes. Percent, duration, and release are provincial. I will not write “10% for 45 days in Ontario” onto your kitchen remodel as if I had read your statute into the PDF. I will record whether the paper names holdback, the amount, the start, and the release. If it is silent, I say so. If it waives holdback, I say that is a lawyer question — not a Nico verdict.

Substantial versus final versus punch-list money

Paying out at substantial completion can leave no money for incomplete work. I look for what is still unpaid after substantial, and what list has to be finished before final payment. Punch-list retainage: a defined list, a deadline, money held. If both fire, I merge them in the UI rather than scare you twice. Ask: what is still unpaid after substantial completion, and how many days do you have to finish the punch list?

Lien waivers, and a Canadian caution

On US jobs I look for lien waivers with each draw from the GC and major subs. Paying the GC does not stop a sub lien. Ask for a partial waiver with each draw and a final waiver at last payment. On Canadian jobs I do not tell an owner to take a waiver in lieu of holdback. That substitution is a lawyer conversation. I will not write it as a tip.

How extras interact with the tail

Change orders sometimes bill 100% when signed. That can skip retainage or holdback. On the change-order checker I ask whether the extra is under the same unpaid tail as the original work, and when it is due — at signing, next draw, or 100% now. Due when signed is leverage in the other direction.

What I record, in one list

• Word used: retainage, holdback, both, neither.
• Percent, if stated.
• Which payments it is taken from.
• What event releases it: substantial, final, punch, a number of days.
• Whether extras follow the same rule.
• Waiver language, if any — flagged, not interpreted.

Questions to send

1. What percent is held back, from which payments, and what has to happen before you invoice for it?
2. What is still unpaid after substantial completion, and what list has to be finished before final payment?
3. Does retainage or holdback apply to this extra the same as the original work?
4. Will I get a partial waiver from you and the major subs with each draw, and a final waiver at last payment?

Why both words appear on Nico

This product is generic for Canada and the US. A US owner who searches holdback will land on Canadian lien articles. A Canadian owner who searches retainage will land on AIA-style forms. I keep both words in titles, FAQs, and the contract checklist so the paper’s vocabulary is not lost in translation. I still will not apply a statute. If your lawyer uses a third word — “retention,” “security holdback,” “deficiency holdback” — I record the word the PDF used and ask what releases it.

Silence is the usual residential miss. The total looks round. Draws look monthly. Nobody named a tail. I mark it. The question is the same in both countries: what percent is held back, from which payments, and what has to happen before you invoice for it. If the answer is “we do not do that,” you have a fact about leverage at punch. I will not dress that fact up as a conclusion about the law.

On extras, ask the tail question again. An extra billed at signing can quietly skip the unpaid remainder that protects the punch list. If the original work had 10% sitting unpaid and the extra is due in full this week, the record just changed. Put that next to the running total. Related: change order versus invoice.

Deposits sit at the other end of the same rope. A large start fee plus no unpaid tail means almost all of the money moved before you can walk a finished room. I will not call that a scheme. I will put the two percents next to each other. Related: contractor deposit before work exists.

Warranty start dates interact with the tail. If warranty starts at substantial and the unpaid money is released at substantial, punch-list work has neither money nor warranty leverage. I look at both clauses. I do not rewrite them. Ask when the warranty starts, what it excludes, and what is still unpaid after substantial completion. Those are two questions on one walkthrough.

If you uploaded a Canadian PDF and a US PDF in the same bid comparison, I will not merge holdback and retainage into one invented term. I will show what each file said. Equalizing allowances is not the same as equalizing statutory tails. I never pick a winner.

Read the release sentence twice. “On substantial completion” and “when the last sub is paid” and “forty-five days after publication of a certificate” are not the same event. I quote whichever one is in the file. If none is in the file, that is the finding. Upload the contract to the bid audit if you want that sentence pulled with the rest of the money section. Keep the answer with the paper. The unpaid tail is only useful if you can point at the sentence later.

What I will not say

I will not say your holdback clause matches a provincial act. I will not say a retainage percent is “normal.” I will not say a waiver is worthless or ironclad. I quote the paper. You decide. If you want that pass on a contract or a change order, use the tools. First completed analysis is free. Related: contractor deposit before work exists, and change order versus invoice.
