Change orders aren’t the problem. Untracked scope drift is.
If you’re a homeowner, the fastest way to get surprise bills is to approve changes verbally, over text, or “we’ll figure it out later.” The fix is a simple system: every change must be written as a delta against the baseline scope.
This post gives you a homeowner-friendly Change Order Template using the only format that scales:
- Add (new work)
- Remove (work no longer included)
- Modify (work changed in quantity/material/method)

Who this is for
Best for: homeowners in active repairs/remodels who expect changes (or already have them)
Use when: your contractor says “we found something” or you want to change materials, layout, or scope
The homeowner rule: no written approval, no work
If a contractor starts “extra work” without a written, priced change order, you lose leverage and your budget becomes a suggestion.
Your standard should be:
- No signature → no work
- No baseline reference → no change order
- No evidence → no approval
Step 1: Identify your baseline (the version you agreed to)
Every change order must reference the baseline. That baseline can be:
- your signed proposal
- your scope list
- your “Repair Packet” scope bullets
- a dated email thread summarizing agreed scope
Write it down in the change order as:
Baseline reference: “Proposal dated ___” or “Scope version ___ dated ___”
Step 2: Write the delta (Add / Remove / Modify)
Add (new work)
Use Add when something was not in the baseline scope and is being added.
Examples:
- Add additional drywall replacement beyond defined area
- Add new circuit for appliance
- Add waterproofing membrane upgrade
Remove (work deleted)
Use Remove when something in the baseline is no longer being done.
Examples:
- Remove planned vanity replacement
- Remove paint in adjacent room
- Remove trim replacement
Modify (work changed)
Use Modify when the work is still “the same line,” but changes in:
- quantity (more/less)
- materials (upgrade/downgrade)
- method (different approach)
Examples:
- Modify flooring from LVP to tile
- Modify cabinet from stock to custom
- Modify repair area from 20 sq ft to 45 sq ft
Step 3: Require evidence for the change
Changes are easier to approve when you can see why they’re necessary.
Evidence examples:
- photos of concealed damage
- moisture meter readings
- inspection notes
- manufacturer lead time / discontinued material notice
- measurements showing quantity increase
If there’s no evidence, require it before approving.
Step 4: Price + schedule impact must be separate
Every change order should state:
- Cost impact: $___
- Schedule impact: ___ days
- Payment timing: due now / due at milestone / due at completion
Avoid “T&M without cap” unless you explicitly agree and understand the risk.

Common homeowner traps (and how to avoid them)
Trap #1: “It’s minor—just do it”
Minor changes stack up. Track them as deltas.
Trap #2: “We’ll settle up at the end”
That turns into a surprise invoice. Approve each delta before work proceeds.
Trap #3: Vague language (“as needed,” “repair area”)
Force boundaries. If the boundary expands, that’s a delta.
FAQs
Do change orders have to be in writing?
They should be. Written change orders prevent disputes and protect both sides. If it’s not written and approved, it’s unclear what was agreed.
When should I sign a change order?
Before the extra work starts. Always.
What if the contractor says it’s “required”?
Ask: “Required by what?” Then request evidence (inspection note, code requirement, photos of concealed damage). If it’s truly required, it becomes an ADD or MODIFY with evidence.
What if we can’t price it exactly yet?
Use a not-to-exceed cap and define what triggers re-approval. Don’t accept unlimited T&M without constraints.
