ExplainerWhat is a change order?
A change order is a written, signed record of a change to a project's original scope — work added or removed, and how it affects the price and the schedule. It amends the contract so the contractor and client agree, in writing, on exactly what changed and what it costs before the work happens. On renovations, it's the single most important paperwork habit for protecting your margin.
Why change orders matter
Renovations change constantly — a client adds a feature, a hidden condition turns up behind a wall, a finish gets swapped. Without a change order, that extra work quietly becomes unpaid work, and "what we agreed" becomes an argument. A signed change order makes every change explicit, approved, and billable.
What a change order should include
- Description of the change.
- Reason — client request, hidden condition, etc.
- Cost impact — an add or a credit.
- Schedule impact — days added, if any.
- Updated total — the new contract value.
- Signatures & date — both parties, before the work starts.
When do you need one?
Any time the work differs from the signed scope in a way that affects cost or schedule. If you catch yourself thinking "we'll sort it out later," that's the moment to write a change order instead. It's part of a healthy renovation management process and keeps client communication clean.

What is a change order?
A change order is a written, signed record of a change to the original scope of a project — added or removed work, and its effect on price and schedule. It amends the contract so both sides agree on what changed and what it costs before the work is done.
What should a change order include?
A description of the change, the reason, the cost impact (add or credit), the schedule impact, an updated contract total, and both parties' signatures with a date. Approve it before doing the work.
Why are change orders important?
They protect your margin and your relationship. Without them, extra work turns into unpaid work and disputes over 'what we agreed.' A signed change order makes every scope change explicit and billable.
When do I need a change order?
Any time the work differs from the signed scope — the client adds something, a hidden condition appears, or a material is swapped. If it changes cost or schedule, it's a change order.
