Change Orders: How to Review Before You Sign

Your contractor walks over with a clipboard and says, “Hey, we found a little issue behind the drywall. Nothing major, just need to move this drain pipe a few feet. Sign here and we’ll keep going.”

You glance at the paper. It says “Change Order #1” at the top and has a number: $1,850.

Do you sign it?

Most homeowners do. And most homeowners regret it later — not because the work wasn’t needed, but because they signed something they didn’t fully understand. A change order is a legal amendment to your contract. It adjusts the scope, cost, timeline, or all three. Once you sign it, you’re agreeing to everything in it — including the parts you didn’t read.

This guide will walk you through exactly what to check before you put pen to paper. Because the five minutes it takes to review a change order can save you thousands of dollars and months of frustration.

What a change order actually is

Let’s start with the basics.

A change order is a written document that modifies your original construction contract. It’s not a verbal agreement. It’s not a text message. It’s not a “we’ll figure it out later.” It’s a formal, signed amendment that changes what you and your contractor agreed to. If the baseline agreement is fuzzy, review what should be in a remodeling contract first; the change order only makes sense against that original scope.

Change orders happen for three main reasons.

Unforeseen conditions. Nobody knew that drain pipe was in that wall. Or that the floor joists were rotted. Or that the electrical panel was overloaded. These aren’t anyone’s fault — they’re discovered conditions that change the work.

Owner changes. You decided you want taller cabinets. Or you want the window moved two feet to the left. Or you want to add a pot filler at the stove. These are intentional changes to the original plan.

Scope clarifications. The original contract said “install bathroom vanity” but didn’t specify who provides the vanity. Now you and the contractor need to agree on that. Technically this should have been in the original contract, but change orders often fill these gaps.

Each reason requires a different level of scrutiny. Let’s look at how to handle all three.

The six things to check on every change order

Every change order you receive deserves a thorough review. Here’s your checklist.

1. The description of work

Read the description carefully. Does it clearly state what’s being changed, why, and how it affects the existing work? Vague language is a red flag.

Good description: “Relocate bathroom sink drain pipe from current position (east wall) to new position (north wall) to accommodate relocated vanity. Includes cutting and patching drywall on both walls, rerouting 2-inch PVC drain line approximately 6 feet, and pressure testing new line.”

Bad description: “Move drain pipe.”

A bad description leaves room for the contractor to do the minimum required work — and then hit you with another change order for the drywall repair, the paint, or the tile that had to be removed. The good description covers everything related to the change, so you know the total cost upfront. If the original scope is the problem, use a homeowner scope document to separate included work from new work.

2. The cost breakdown

A change order should show you what you’re paying for. Not just the total, but the line items that add up to that total.

Look for:

• Materials: what’s being used and how much it costs
• Labor: how many hours and at what rate
• Subcontractor costs: if a specialty trade is involved
• Overhead and markup: how much the contractor is adding on top
• Permit fees: if the change requires an updated permit

If the change order only shows a total price with no breakdown, ask for one. You have a right to know what you’re paying for. For context on labor, materials, and markup, compare the request against this contractor pricing breakdown.

3. The timeline impact

Every change affects the schedule. Some changes add a day. Others add a week. The change order should tell you which one you’re dealing with.

If the change order says “no schedule impact” but the change involves relocating a structural wall, that’s probably not accurate. Ask the contractor to walk you through how the change affects the overall timeline — and get the revised completion date in writing. If the schedule already felt optimistic, revisit how to compare contractor timelines before you accept a no-delay answer.

4. The effect on other work

A change rarely happens in isolation. Moving a drain pipe might mean the tile layout needs adjusting. Adding a window might affect the exterior siding, the interior drywall, and the trim package.

A well-written change order accounts for these ripple effects. If yours doesn’t, ask: “What else does this change touch?” The answer might point to additional costs that should be included now rather than hit you as a separate change order next week. This is also where scope creep starts if every related item becomes its own surprise.

5. Credit for omitted work

Sometimes a change order removes work as well as adding it. If you decided to skip the built-in shelving you originally wanted, the change order should show a credit for that omission.

Check that the credit is fair. If the original contract charged you $2,000 for the shelving and the change order only credits you $1,200, ask why. There might be legitimate reasons — materials already purchased, labor already spent — but you deserve an explanation. If the omitted work was tied to an allowance, review allowances in construction contracts so the credit is calculated from the right baseline.

6. Signature blocks for everyone

A valid change order should be signed by both you and the contractor. Some contracts also require the architect or designer to sign. Make sure everyone who needs to sign has a place to do so — and that you get a copy after it’s signed.

When to slow down and ask more questions

Not every change order needs hours of review. A $150 change order to swap a light fixture is probably fine. But some situations demand extra caution.

The change order arrived mid-task

If the contractor stops mid-morning to hand you a change order and wants a signature before lunch, slow down. This is pressure-tactics territory. A legitimate change order can wait a few hours or overnight while you review it.

A polite response: “I’d like to review this carefully. Can we pick a time this afternoon to go over it together?”

The change order fixes a mistake

If the contractor needs to move a window they installed in the wrong location, that’s their mistake — not a change to the scope. You shouldn’t pay for that. Make sure the change order clearly states who’s responsible for the cost. If it’s unclear, ask directly: “Is this a warranty issue or a scope change?”

The change order feels like the original scope

Sometimes a contractor writes a change order for work that was implied in the original contract. If you feel like you’re paying twice for something you thought was included, push back. “I thought this was part of the original bid. Can you show me where it was excluded?”

If the original contract was vague, that’s a problem — but it’s one you share with the contractor. A good-faith discussion usually resolves it.

The change order total is significant

Any change order that adds more than 10% to your original contract price deserves extra scrutiny. Ask for a detailed breakdown. Consider getting a second opinion from a designer or architect. And make sure you understand how paying for this change affects your overall budget.

How change orders affect your payment schedule

This is a detail most homeowners miss.

Your original contract has a payment schedule tied to specific milestones: “10% at signing, 25% when foundation is complete, 25% when framing is done,” and so on. A change order adds cost, but it doesn’t automatically adjust the payment schedule.

Ask: “How will this change order affect my payment schedule? Will I need to pay for this immediately, or will it be added to the next draw?”

Some contractors expect payment for change orders within 30 days. Others roll them into the next progress payment. Neither is wrong, but you need to know which one applies so you can plan your cash flow.

For the full payment context, read construction payments: deposits, progress, and final checks before you decide whether a change belongs in the next draw or the final payment.

The difference between a change order and a change directive

This is a technical distinction, but it matters when things get contentious.

A change order is signed by both parties. You and the contractor agree on the scope, cost, and timeline, and you both sign.

A change directive is a written instruction from you (or your architect) directing the contractor to proceed with a change before the cost is finalized. It’s used when the work can’t wait for a full cost agreement — for example, if an emergency repair is needed to prevent further damage.

Change directives should be rare. When one shows up, understand that you’re authorizing work without knowing the final cost. That’s risky. Only sign a change directive if the situation genuinely can’t wait.

How to document your approval process

Good documentation prevents disputes. Here’s a simple system.

Create a folder — physical or digital — specifically for change orders. When you receive one, log the date, the change order number, a brief description, and the dollar amount. Note when you approved it and when you signed. The same record-keeping habits in how to document project decisions apply here, just with extra attention to dollars and dates.

This takes five minutes per change order and gives you a clear record if there’s ever a disagreement about what was approved and when.

Quick Answers

Q: Do I have to sign a change order immediately?

No. You have the right to review it. A reasonable contractor will give you time to read and ask questions. If someone pressures you to sign on the spot, that’s a red flag.

Q: Can I refuse a change order?

Yes. If you don’t agree with the scope, cost, or schedule impact, you can refuse to sign. But understand the consequences: the contractor may not proceed with the changed work, and that might delay or stop your project. Work through the disagreement collaboratively rather than just saying no.

Q: What if the work is already done when I get the change order?

This is not acceptable practice. Work should not proceed on a change until both parties have signed. If your contractor did work before getting your signature, raise the issue. Some contractors do this as a “better to ask forgiveness than permission” tactic. A legitimate contractor will walk through the work with you and come to a fair agreement.

Q: How many change orders is normal?

There’s no magic number, but a well-planned project might have 3-8 change orders. A project with 20+ change orders usually points to insufficient upfront planning. That said, older homes and complex renovations naturally generate more change orders.

Q: Can a change order reduce the price?

Absolutely. If you decide to omit something, remove a finish, or simplify a detail, the change order should show a credit. Don’t assume the contractor will proactively offer credits — ask about them.

Q: Should my designer or architect review change orders?

If you have a designer or architect involved in your project, yes — especially if the change affects design intent, structural elements, or code compliance. Their fee may include change order review, or they may charge for it separately. Ask upfront.

Q: What if I disagree with the cost of a change order?

Start with a conversation. Ask for the breakdown. If you still disagree, consider getting an independent estimate from another contractor. If the gap is significant, your contract may include a dispute resolution process — mediation, arbitration, or both.

Q: Do change orders extend the warranty?

Usually not. Change order work is typically covered by the same warranty as the original contract, but the warranty period starts from substantial completion of the original project, not from the date of the change order. If the change order adds significant systems work (like a new HVAC zone), negotiate to have that specific work carry its own warranty period.

Q: Can I write my own change order?

Yes. If you want to change something, you can initiate the change order process. Put your request in writing: “I’d like to change the kitchen countertops from laminate to quartz. Please provide a change order showing the additional cost and schedule impact.” This puts the ball in their court and creates a paper trail.
