Retainage on Change Orders Is Quietly Eating Your Pay

You finished the job. Punch list is done, the owner is happy, and you are waiting on the last check. Then you actually do the math on what is still outstanding and it is bigger than you thought — because retainage was not just held on your base contract. It was held on every single change order you ran through the job, and nobody, including you, ever added those up.

That is the quiet version of getting burned. No argument, no dispute letter, no lawyer. Just five percent here and ten percent there on twenty-two change orders, sitting in someone else’s bank account eighteen months after you hauled off the last dumpster. Retainage on change orders is one of the most reliable ways contractors lose money they already earned, and it is almost always a paperwork problem, not a payment problem.

Heads up: this is general information, not legal advice. Retainage requirements change and vary by state and by project type — confirm the current rules with your state’s licensing board, contracting authority, or a licensed attorney before relying on them.

What retainage actually does to a change order

Retainage (some contracts call it retention) is the slice of every progress payment the owner or GC holds back until the work is complete and accepted. On the base contract you plan for it. You price it in, you know it is coming, and you chase it at closeout.

Change orders are different, because a change order is money that did not exist when you signed. Most contracts apply retainage to the revised contract sum, which means every approved change order silently increases the pile being held. Add $180,000 in change orders to a job with 10% retention and you have just parked another $18,000 in someone else’s account — on work you did not budget for, financed out of your own cash flow, and probably never tracked separately.

Here is the part that stings. Base contract retainage is easy to prove: one number on one document everybody agrees on. Change order retainage is spread across a dozen scattered emails, a couple of texts, and a Word file somebody renamed. When it is time to collect, the burden is on you to reconstruct it — and if your change order paperwork is loose, some of it will not be collectible at all.

The real cost when change order retainage goes sideways

Let us make it concrete. A commercial interiors sub runs a nine-month job. Base subcontract $640,000. Over the job they issue 19 change orders totaling $214,000 — added millwork, a rerouted feeder, three rounds of owner-driven finish changes, and a pile of T&M tickets that later got rolled up.

• Retainage held on base: $64,000 at 10%. Planned for. Fine.
• Retainage held on change orders: $21,400. Not planned for, not tracked.
• Change orders built on verbal or email-only approval: 6, worth $47,000.

At closeout the GC releases retainage on the base contract, because that number is not in dispute. Then they push back on the six unsigned changes. Now you are not fighting for $21,400 of retainage — you are fighting for $47,000 of principal plus the retainage sitting on top of it, with no signed document to put on the table. You will probably settle. You will probably settle low. And you will absorb the difference out of a margin you priced at 12%.

The damage does not stop at the check:

1. Cash flow. You already paid your crew and your suppliers for that work. The retainage is not profit sitting idle — it is working capital you loaned out for free.
2. Deadlines you miss. Lien and bond claim deadlines in most states run from a date tied to when you last furnished labor or materials, not from the day someone finally tells you no. Sit on unpaid change order retainage for months and you can run the clock out on your best leverage.
3. The relationship. Every dollar you chase at closeout is a hard conversation with the person who decides whether you get the next job. That is a bad trade for money you should have locked down months earlier.
4. You repeat it. Contractors who lose money this way usually change nothing. They quietly write it off and run the next job the same way.

Five ways contractors lose retainage on change orders

1. Not knowing retainage applies to changes at all

Plenty of contractors assume retention applies only to the original contract sum. Read your contract. If it says retainage is calculated on the contract sum as adjusted, every change order you sign adds to the withheld total. Know that number before you sign the change, not after.

2. Building the work before the change order is signed

This is the big one. Unsigned change orders do not just risk the principal — they poison the retainage claim sitting on top of it. If the owner disputes whether the work was ever authorized, the retainage on it becomes a rounding error inside a much bigger fight. Signed paperwork before the crew starts is the whole game.

3. Rolling T&M tickets up at the end

Ten weeks of daily tickets bundled into one change order at final billing is an invitation to negotiate. Convert tickets into a signed change order weekly, while the work is still fresh in everyone’s memory.

4. No log

If you cannot produce a single sheet showing every change order, its value, its status, the date it was signed, and the retainage held against it, you cannot collect efficiently. You will be digging through email threads while the person holding your money waits you out.

5. Never showing retainage as a visible line

Retainage that does not appear as a running balance on your own paperwork is retainage you will forget to chase. It should be a number you can read in five seconds.

Fix one: put every change order on a proper spreadsheet

If you run your job from a laptop and you like seeing the whole picture at once, use a spreadsheet built for this. Our free Excel change order template gives you a clean, professional change order form with line items, markup, tax and the revised contract value calculated for you — plus a change order log tab that tracks every change on the job in one place. That log is exactly what you need at closeout: dates, values, approval status and a running total you can hand to a GC without apologizing for it.

Add a retainage column to the log, set it to your contract percentage, and you get a live figure for how much of your change order money is being held right now. It takes about a minute to set up and it turns retainage from a nasty surprise into a number you can invoice against. You can download the free change order spreadsheet and use it on every job you run — no charge, no catch.

Fix two: get changes signed on the spot, from a phone

Spreadsheets are great for tracking. They are slower at the part that actually protects you: getting a signature before the work starts. If your problem is that changes get approved in a truck at 7am and written up three weeks later, the approval needs to happen at the moment of the conversation.

That is what the free digital change order tool is for. You type the change on your phone while you are standing in front of the client, hit send, and they sign it on their own phone in about thirty seconds. The revised contract value updates itself, everything is timestamped, and you finish the job with a complete signed record of every change — which is precisely what you need when you go to collect the retainage held against them. It is genuinely free, and if you are wondering how that works, we explain it on the pricing page.

Most contractors end up using both. The spreadsheet lives on the office machine for tracking and closeout; the digital change order tool lives in your pocket for getting the signature before anyone swings a hammer. Pick whichever fits how you work — the point is that the change is documented before it is built.

What the law says, and why you should check yours

Retainage is heavily regulated, and the rules differ by state and by whether the project is public or private. A few examples that show how much variation there is:

• California. Senate Bill 61 caps retention on private construction contracts at 5% for contracts entered into on or after January 1, 2026, replacing the old 10% industry norm. Retention withheld from any individual progress payment may not exceed 5%, and total retention across the contract may not exceed 5% of the contract price. There are exceptions, including residential-only projects of four stories or fewer, and situations where a party requests performance and payment bonds in writing and does not receive them.
• New York. For private construction contracts entered into on or after November 17, 2023, an amendment to the state’s Prompt Payment Act caps retainage at 5% of the contract sum, and contract terms requiring more than that are void.
• New Mexico. Retainage is prohibited on most publicly and privately funded projects.
• Texas. House Bill 3485, applying to contracts entered into on or after September 1, 2023, gives contractors and subcontractors a statutory right to decline owner-directed additional work where there is no written, fully executed change order and the aggregate value of unexecuted change orders for that additional work exceeds 10% of the original contract or subcontract amount — without being liable for delay damages for that decision. The right is not waivable by contract.

Broadly, states that legislate retainage tend to cap it at either 5% or 10%, and on private work in states without a cap it usually comes down to what your contract says. Texas is worth noting even if you never build there, because it shows the direction of travel: legislatures increasingly treat an unsigned change order as a legitimate reason to stop work. Do not lean on that. Get the signature.

Again — general information, not legal advice. Verify anything above with your state’s licensing board, contracting authority or an attorney before you act on it.

Your retainage change order checklist

Run this on every job. Ten minutes at the start, five figures saved at the end.

1. Read the retainage clause before you sign. Note the percentage, whether it applies to the adjusted contract sum, and what triggers release.
2. Check whether your state caps retainage for this project type. If your contract exceeds the cap, raise it before you sign, not at closeout.
3. Set up your change order log on day one, with a retainage column.
4. Never build a change without a signature. Not a text, not a nod — a signature.
5. Convert T&M tickets into signed change orders weekly.
6. Show retainage as a visible line on every invoice, including retainage held on change orders.
7. Calendar your lien and bond claim deadlines the moment a change order is signed.
8. At substantial completion, submit one clean retainage release request covering the base contract and every change order, backed by the log.

None of that is complicated. It is discipline applied to paperwork most contractors treat as an afterthought — and it is the difference between collecting everything you earned and writing off a chunk of it as the cost of doing business. If you want more on this side of the job, the rest of our writing lives on the ChangeOrdersPro blog, and our guide to change order markup and overhead covers the other half of the margin problem.

Frequently asked questions

Is retainage held on change orders as well as the base contract?

Usually yes. Most construction contracts calculate retainage on the contract sum as adjusted, which means every approved change order increases the amount being withheld. Read your retainage clause before you sign, and track the retainage held against change orders separately — that is the money contractors most often forget to collect.

How do I track retainage on change orders without extra software?

A spreadsheet does it fine. The free Excel change order template includes a log tab listing every change order with its value, date and approval status. Add a retainage column set to your contract percentage and you get a live total of how much change order money is being held. It is free to download and use on any job.

Can retainage on a change order be released before the job is finished?

Sometimes. Some contracts and some state prompt payment statutes allow reduced or released retention once a defined milestone is reached, such as 50% completion or substantial completion. It depends on your contract language and your state’s rules, so check both. If your contract is silent, negotiating a release trigger before you sign is far easier than arguing for one at closeout.

What happens to retainage on a change order that was never signed?

It becomes part of a much bigger problem. If the work was never authorized in writing, the dispute stops being about a retainage percentage and becomes about whether you get paid for the work at all. Getting a signature before the crew starts is the only reliable protection — the free change order tool exists for exactly this: send the change from your phone and have it signed in about thirty seconds.

Is any of this legal advice?

No. This is general information only. Retainage caps, release timing and change order requirements change and vary by state and by project type — confirm the current rules with your state’s licensing board, contracting authority or a licensed attorney before relying on them.
