Change Orders, Explained
Almost every remodel changes at least a little between the contract and the finish, and the change order is the tool that keeps those changes fair and documented. Handled well, it protects both you and the contractor. Handled badly — verbally, vaguely, or after the fact — it is where budgets quietly balloon and disputes begin. This guide explains what a change order is, when you need one, and how to keep them under control.
The short version
- A change order is a written amendment to the contract that alters scope, price, or schedule.
- They arise from your requests, hidden conditions, or unavailable materials.
- A proper change order is priced and signed before the work proceeds.
- Verbal changes are the enemy — get every one in writing.
- A contingency budget cushions the changes you cannot foresee.
What a change order is
A change order is a formal, written amendment to your original contract. It describes what is changing, what it costs (or credits back), and any effect on the schedule, and both you and the contractor sign it before the changed work happens. It exists because the original contract priced a specific scope — the moment that scope shifts, the price and timeline may need to shift too, and the change order is how that is done transparently.
Why changes happen
Change orders are normal, not a sign something went wrong. They usually come from one of three sources:
- You change your mind. You upgrade a finish, add a feature, or decide to move a wall after seeing the space framed. This is the most common and the most controllable source.
- Hidden conditions. Demolition reveals rot, outdated wiring, failing plumbing, or a surprise behind the walls that has to be addressed.
- Availability. A specified material is discontinued or badly delayed, forcing a substitution that costs more or less.
| Change source | Example | Controllable? |
|---|---|---|
| Homeowner request | Upgrading countertops mid-job | Yes — decide early |
| Hidden condition | Rot found during demo | No — use a contingency |
| Material availability | Discontinued tile | Partly — approve substitutes fast |
What a proper change order includes
A trustworthy change order is specific and complete. It should state exactly what work is being added, removed, or altered; the cost change, broken out rather than a vague lump; the effect on the schedule; and both signatures with a date. Most importantly, it is signed before the work is done — not presented as a surprise on the final invoice. If a contractor wants to proceed on a handshake and “figure out the cost later,” that is exactly the pattern to refuse.
Pro tip — agree on the change-order process before you start
Do not wait until the first change to learn how your contractor handles them. During the contract stage, ask how change orders are priced and approved, and get that process in writing. Knowing that every change will be documented and signed before work proceeds sets the tone for the whole project and prevents the “we’ll settle up at the end” surprise.
How to keep change orders from piling up
You cannot eliminate change orders, but you can minimize them. Make as many decisions as possible before construction starts — finalize your selections and plans so you are not redesigning mid-build. Build a contingency into your budget, a sensible percentage set aside specifically for the surprises demolition will find. And when a change does come up, decide quickly, because indecision stalls the crew and delay has its own cost.
The budget reality
Experienced homeowners treat the contract price as a floor, not a ceiling, and plan for it to rise somewhat through change orders. That is not pessimism — it is how remodels work, especially in older homes. A contingency fund turns an alarming mid-project surprise into a manageable line item, and keeps a discovered problem from forcing you to choose between going over budget and leaving work undone.
FAQ
Are change orders a bad sign?
Not by themselves — some are unavoidable, especially when demolition reveals hidden conditions. What matters is how they are handled: a good contractor documents and prices each one before proceeding. Frequent, vague, or after-the-fact changes are the real warning sign.
Do I have to accept a change order?
For your own requests, you decide. For hidden conditions like rot or code issues, some fixes are genuinely necessary to finish the job safely and legally, but you are still entitled to a written, priced change order before the work proceeds — and to a second opinion if something seems off.
How much should I budget for changes?
Setting aside a contingency of a sensible percentage of the project cost is a common practice, with a larger cushion for older homes that are more likely to hide surprises. It converts an unexpected problem into a planned line item rather than a crisis.
What if a contractor does extra work without a change order?
Do not pay for undocumented extras added to the final bill without your prior written approval. Insist that every change be a signed change order before the work happens; that expectation, set at the start, is your best protection against surprise charges.
