Change orders on a Portland remodel, explained
The single biggest source of remodel sticker shock — what a change order really is, why it happens, how to read one, and how to keep the avoidable kind to a minimum.
Ask anyone who's been burned by a remodel and the story usually involves change orders: the project that “started at $150,000” and finished well past it. But change orders aren't the enemy. They're how a contract adapts to reality. The trick is telling the legitimate ones from the avoidable ones, and both from the kind that mean you hired wrong. Here's how remodel change orders really work.
What a change order actually is
A change order is a formal, written amendment to your construction contract. It documents a change to the scope (what's being built), the price, and often the schedule — and, done right, it is reviewed and signed by both you and the contractor before the changed work is performed. That “before” is the whole point: a change order exists so there are no surprises on the final invoice. If work changes and you find out when the bill arrives, the process has failed.
The two kinds — and they're very different
Nearly every change order falls into one of two categories, and telling them apart tells you a lot:
- Owner-requested. You change your mind — a different tile, a moved wall, an added skylight. These are entirely legitimate and entirely within your control. They cost the most when they come late, after the related work is already built.
- Discovered conditions. The crew opens a wall and finds knob-and-tube wiring, rot, a hidden leak, an un-level floor, or a foundation issue. In Portland's older homes this is common and often genuinely unforeseeable — no one can bid what they can't see. This is exactly what your contingency is for.
A reasonable number of discovered-condition change orders on a 1915 Foursquare is normal. A steady stream of change orders for things that should have been in the original drawings is not — that's either sloppy estimating or a deliberate strategy.
How to read a change order
A good change order is short and unambiguous. Before you sign one, confirm it states:
- What's changing — the specific work added, removed, or modified.
- The cost — a clear price for the change, not a vague “to be determined.”
- The schedule impact — how many days, if any, it adds to the timeline.
- Sign-off — space for both parties to approve, dated, before work begins.
If a change order is missing the price or the schedule impact, don't sign it — ask for a complete one. Vague change orders are how small changes quietly compound into a blown budget.
How to keep the avoidable ones low
You can't prevent every change order, but you can prevent most of the avoidable kind:
- Decide early. Lock your design and finish selections before construction starts. Late decisions are the number-one source of avoidable change orders — see our remodel process & timeline guide.
- Keep a real contingency. Budget 10–15% you don't touch, specifically for discovered conditions. Our cost guides build this in — for kitchens and whole-home renovations especially.
- Hire detail. A firm whose original scope and allowances are thorough leaves far less to become a change order later.
The red flag: change orders as a business model
Here is the pattern to watch for. Some contractors win the job with a low bid, knowing the scope is thin, then recover their margin through a steady drip of change orders once you're committed and it's painful to switch. This is why the lowest bid is so often the most expensive project — our guide to how remodel estimates work shows how to spot a thin one before you sign. The other defense is upstream, at hiring: our guide to vetting a Portland remodeler covers the questions — about scope detail and the change-order process — that surface this before you sign.

Frequently asked questions
- What is a change order in a remodel?
- A change order is a written, signed amendment to your construction contract that documents a change to the scope, price, or schedule after the contract is signed. It either adds, removes, or modifies work — and it should always be in writing, with the cost and any schedule impact stated and approved before the work happens.
- Are change orders normal, or a red flag?
- Some are completely normal — especially discovered-condition change orders in older Portland homes, where opening a wall reveals something no one could have seen. What's a red flag is a steady stream of change orders for things that should have been caught in design, or a contractor who uses them to make up a lowball bid. The cause matters more than the count.
- How do I avoid change orders?
- Most avoidable change orders come from decisions made late. Lock your design and finish selections before construction starts, keep a contingency for genuine surprises, and hire a firm whose original scope is detailed enough that little is left vague. You can't eliminate discovered-condition changes in an old home, but you can budget for them.
- Do I have to pay for a change order I didn't approve?
- You shouldn't. A legitimate change order is approved in writing before the work is done. If a contractor performs extra work and bills you after the fact without sign-off, that's exactly the practice a clear written change-order process is meant to prevent — and a reason to confirm that process before you sign the contract.
