When a contractor presents a change order after doing the work, first compare the extra work with the signed scope and change-order clause. Request the reason, labor, materials, markup, date, and claimed approval in writing. Do not assume the whole charge is valid or invalid because contract rules and state law vary.
A 2026 homeowner received a proposed $3,200 increase on a $4,500 demolition contract after quantities exceeded the contractor estimate. Other threads describe extra work priced only after completion. The core problem is approval and risk allocation.
Start here: a practical action plan
- Collect the original scope.
- Itemize added work.
- Identify the claimed approval.
- Require signed future changes.
- Signing a backdated form.
- Treating every disputed dollar alike.
- Ignoring the contract notice clause.
Reconstruct the original agreement
Collect the signed contract, drawings, specifications, allowances, exclusions, messages, site photos, invoices, and the change-order clause. Highlight the original work, conditions the contractor agreed to investigate, and any written notice required when hidden conditions appear.
FTC guidance emphasizes putting promises, scope, cost, and dates in a written contract. The effect of an unsigned or retroactive change depends on the contract and state law. Use the state consumer office or qualified local counsel for legal interpretation.
Worked example: separate scope from price
Example: the original contract is $18,000. The contractor requests $4,800 for added plumbing. The homeowner finds a text approving only a $1,200 camera inspection and temporary repair. The amount without identified written approval is $4,800 - $1,200 = $3,600.
The $3,600 is the amount requiring further analysis, not automatically the amount owed or withheld. Ask whether the added work was necessary to protect property, requested verbally, already inside the original scope, or governed by a contractual emergency provision.
| Hypothetical change audit | Calculation | Amount |
|---|---|---|
| Original contract | Signed scope | $18,000 |
| Requested change | Added plumbing | $4,800 |
| Documented approval | Inspection and temporary repair | $1,200 |
| Amount requiring review | $4,800 - $1,200 | $3,600 |
Test claimed approval and cost evidence
Request an itemized description, quantities, labor hours and rate, material invoices, subcontractor invoice, overhead, profit, tax, schedule effect, and photographs of the condition. Ask when the contractor discovered the issue and why pricing and approval did not occur first.
Compare the claimed approval with the contract. A discussion that a problem exists is not necessarily approval of a specific scope and price. Conversely, conduct and emergency circumstances can matter under local law. Preserve facts rather than rewriting the history.
Set a written rule for every later change
For disputed dollars, communicate the exact lines in writing and continue handling undisputed contract obligations as advised locally. Do not threaten, erase messages, or sign a backdated form. Obtain local guidance before withholding money or terminating the contract.
For future changes, require a numbered form stating scope, added or reduced price, new contract total, schedule effect, allowance credit, signatures, and approval date before work begins. Keep an emergency contact and documentation rule for conditions that cannot safely wait.
- Collect the original scope and clause.
- Itemize the added work and price.
- Identify the exact claimed approval.
- Require signed changes going forward.
Frequently asked questions
Do I owe for a change order I did not sign?
It depends on the contract, facts, and state law. Document the scope, approval, and cost and get local advice.
What should a change order include?
Include the changed scope, price or credit, new total, schedule effect, and dated approvals.
What if the contractor found hidden damage?
Ask for prompt photos, an explanation, options, and a priced change before work when safety permits.
Can a text message approve extra work?
It may be evidence of approval, but its meaning depends on the wording, contract, and local law.
Should I refuse the entire next payment?
Separate undisputed work from disputed change lines and obtain local guidance before withholding payment.
How do I prevent retroactive change orders?
Put a written approval process and emergency exception in the contract and enforce it consistently.
