A guy is finishing his basement. He wants a built-in bar with a vertical cedar face — "probably 40 to 50 pieces, about 3 feet long, 2×4 cedar." Normal basement remodel scope. The contractor nods, picks up his clipboard, and asks one question:
"How close to 2×4 do you want it?"
He shrugs. "I don't know — pretty close, I guess."
What he doesn't know is that "2×4" is the nominal size of lumber. A 2×4 you buy at Home Depot is actually 1½ × 3½ inches, because milling shaves about ⅛ inch off every side. So when his contractor heard "pretty close to 2×4" — and asked the question knowing the answer would matter — he didn't say a word. He went and bought 3×6 rough stock and milled it down to true 2×4.
The bill came in at five times what the homeowner expected. When he complained, the contractor pointed at the order: "I had to mill it down from 3×6 stock. I asked you how close you wanted."
The whole story is up on r/MaliciousCompliance (and recapped on TwistedSifter). The homeowner paid, grudgingly, and never hired the contractor again. The contractor was technically correct. The homeowner was technically gut-punched.
If you've ever stood in your half-demolished kitchen holding an invoice you weren't expecting, you've been in some version of this story.
Change orders aren't the problem. Vague change orders are.
We've all been here
A change order — a written amendment to your remodeling contract — isn't the enemy. Walls open up. Tile goes out of stock. The city wants another inspection. Some changes are nobody's fault. They're part of the job.
What makes a change order go sideways is almost never the change itself. It's how it shows up. We've watched the same three patterns play out over and over:
1. The verbal surprise. Someone on the crew mentions something offhand. We nod. Two weeks later it's a $1,400 line item we never saw coming.
2. "That was already included." We assumed painting was in the bid. The contractor says it wasn't. The contract is vague enough that both of us have an argument.
3. The markup that doesn't add up. A $400 part shows up at $1,100. Nobody can explain the math when we ask.
These aren't rare. They're the most common reason remodeling friendships end. And we — the homeowners — are usually the ones who lose, because by the time the dispute starts, our house is torn apart and we have no leverage.
A second story that's just as familiar
Different homeowner, different thread, same pattern in a different costume.
He'd hired a painter for most of a 2,700 sq ft house. His wife had been texting the painter's wife about colors. The painter's wife then asked them to "send everything by email to formalize the colors and finishes." They did. His wife had changed her mind on the master bedroom color — so the email had the new color. The painter never opened the email. Painted the master in the old color from the texts.
When the bill came, the homeowner paid for everything except half the master — $300 short of the full invoice. The painter was furious. Now they're talking small claims court.
Nobody in that story is obviously evil. There's no fraud, no markup scheme. There's just scope agreed in three different channels with no single source of truth. That's how most "this was supposed to be included" fights actually start.
It's exactly the pattern we kept seeing — which is honestly why we built RemoDone in the first place. The whole idea is to pull the messy contract, texts, and emails into one shared view, so a change made in channel 3 doesn't quietly contradict channel 1 two weeks later.
Paper before work
In many states — and in almost every well-run project — the linchpin is whether the change was clearly written down before the work happened. A couple of examples that show how serious states get about this:
- California — Business & Professions Code §7159.6 says an extra work or change order isn't enforceable against the homeowner unless it's signed and spells out the scope, the cost, and the effect on the schedule.
- New York — General Business Law §771 requires home improvement contracts of $500+ to be in writing, with all amendments signed by both parties.
- Massachusetts — under Chapter 142A, the line from construction lawyers in the state is blunt: "verbal change orders are worth the paper they are not printed on."
Many other states have similar expectations through home improvement statutes, licensing rules, or ordinary contract law. (We're not lawyers, and this isn't legal advice — if we're in an actual dispute, a contractor attorney in our own state is the right call.)
The practical takeaway is the same everywhere: before we sign or agree to anything, we can ask one question that's almost magical in how it changes the conversation —
"Can we put this in writing first?"
That's not adversarial. That's normal. A contractor who pushes back on it is telling us something.
What "normal" actually looks like, with numbers
It helps a lot to know what's typical, because the panic in a change-order moment usually comes from not knowing. Here's roughly where things land.
How much markup is normal? There's no national cap. The industry conventions cluster around these bands:
- 10–20% combined overhead and profit is the conservative band — what insurance adjusters default to ("10 and 10") and what well-drafted residential contracts often specify (United Policyholders, Levelset).
- 20–35% is mainstream for residential remodels. Smaller jobs, more complex scope, and design-build firms cluster at the top of this range (JLC Online, construction2style).
- Above 35% isn't automatically wrong, but it should come with a clear reason — special risk, rush, or a tiny change that's expensive to mobilize for.
One thing most of us don't notice: "10 and 10" compounds. $1,000 of cost + 10% overhead = $1,100, plus 10% profit = $1,210. So "10 and 10" is really 21%, not 20% (R&R Magazine).
How much should change orders add up to? Industry-wide, change orders on remodels typically run 10–25% of the original contract value (Hogan Design & Construction summary). Well-managed design-build projects can stay under 5% (Trimble Constructible). Older homes, vague bids, and lots of late design decisions push us toward the top of the range.
If our changes are tracking near the high end, that's not automatically a sign of a bad contractor — but it's a reason to ask questions. We can pull out the original bid, list every change, total them up, and just ask: "Where are we relative to the base contract?" If the contractor can show us a clean tally and explain each item, we're probably in good shape. If they can't, that's our answer.
Our 5-minute defense, before signing anything
Before signing the next change order that just got handed to us:
1. Ask for the breakdown. Direct labor (hours × rate). Materials with the receipt or quote. The sub's invoice if one was used. Markup as a separate line. A reputable contractor will hand this over. If they get cagey, that itself is information.
2. Find the markup clause in our contract. Search for "change order," "overhead," or "markup." If it says 15% and we're being charged 30%, that's not just a negotiation — it may contradict the contract.
3. Check whether it's in writing and signed before the work. In many states - and in almost every well-run project - this is the linchpin. If the work hasn't started yet, we're in a strong position to say "hold on."
4. Get one outside number. A 20-minute call to another GC or a handyman about the same scope tells us whether the price is real (Nolo's guide walks through this).
When to walk away from the table for an hour
A good contractor doesn't get defensive when we ask these questions. They'll show us the math. They've answered them a hundred times.
A contractor we should be careful with gets vague. They invoke "industry standard" without showing us anything. They push us to sign right now because "the guys are here."
That pressure is the signal. Take a breath, take a photo of the invoice, and step away for an hour. The job will be there when we come back. So will our right to ask.
We hired a contractor for their judgment. We're allowed to use ours, too.
The three things we want to remember
- "Can we put this in writing first?" is the single most important sentence we can say at the moment a change order appears.
- 10–20% markup is conservative. 20–35% is mainstream. Above that needs a real reason. And total change orders typically run 10–25% of the original contract — not zero.
- A good contractor will show us the math. A bad one will pressure us to skip it. The pressure itself is the answer.
