A Customer Blames You for a Failed Inspection That Isn't Yours: Decision Tree

Why this matters

An inspection fails, the correction notice lands, and the customer's first instinct is to call the last contractor who touched the property: you. Sometimes the cited item really is yours. Often it is another trade's work, the previous owner's DIY, a pre-existing condition the inspector is now enforcing, or the inspector reading your permit as if it covered the whole system. If you absorb blame that is not yours, you eat a return trip and a correction you were never paid for; if you brush off a real miss, you lose the customer. The way out is not to argue. It is to read the notice, match each cited item to who actually did that work, and let the paper decide.

Start here: read the correction notice, not the customer

Do not respond to the customer's summary. Get the actual written correction notice from the AHJ (authority having jurisdiction, the local official who enforces the adopted code) and read the specific cited items. Each item names a condition and usually a code section. Your whole diagnosis is matching each cited item to the scope of work it belongs to. Until you have the notice in hand, you are arguing about feelings, not findings.

If the cited item is your work

Own it fast and cleanly. If the notice cites something inside the scope you were permitted and paid for, that is a warranty-grade correction and you fix it at your cost, on your schedule, without drama. A tech who corrects their own miss quickly keeps the customer; one who litigates it loses them even when they eventually comply. Make the correction, request the re-inspection, and document the close-out.

If the cited item is another trade's or a prior contractor's work

This is the most common case, and the paper trail is your defense.

• Match the cited item to your permit scope. If your permit was for one system and the citation is on another, it is not yours to correct.
• Show the customer the notice next to your contract. Point to the item, point to your scope, and let them see the two do not overlap. You are not accusing anyone; you are reading the document.
• Do not correct another trade's work uninvited, even to be helpful. Touching it can transfer liability to you and can require a permit or license you do not hold.
• Offer a path, not a fix. Tell the customer who owns the item (the other trade, the prior contractor, or a new scope they can hire out) and what it will take to clear it.

If it is a pre-existing or grandfathered condition

Sometimes an inspector flags a condition that was legal when it was installed and is only being enforced now because the property is under an active permit. That is not your defect and not the prior installer's, either.

• Confirm with the AHJ whether the item is a true present violation or a grandfathered condition being pulled into current code by the open permit.
• If the AHJ is requiring it as a condition of closing the permit, it becomes a new scope. That is a change order and a conversation about who pays, not a free correction.
• Do not quietly fold it into your job to make the failure go away. That sets a precedent and hides the real cost.

If the inspector conflated your permit with the whole system

Occasionally the failure is a misread: the inspector treated your limited permit as if it covered everything connected to it. Handle this with the AHJ, respectfully.

• Ask the inspector, in person or in writing, to identify the code basis for the cited item and how it falls under your specific permit.
• If it genuinely does not, ask for the notice to be corrected to reflect the actual permitted scope.
• Keep it professional. You want this inspector to pass your next ten jobs, so you are clarifying scope, not scoring a point.

If it is a genuine safety hazard, regardless of who owns it

If the cited condition is an immediate danger (combustion gas, exposed live conductors, backflow into potable water, a structural issue), say so plainly to the customer even when it is not yours to fix. Advise that it be made safe before the system is returned to service. You can decline to correct it and still be the one who told them the truth in writing.

Recap: the order to work it

1. Get the written correction notice and read the specific cited items.
2. Match each item to the scope that actually did that work.
3. If it is yours, correct it fast at your cost and re-inspect.
4. If it is another party's, document, show the customer the notice against your contract, and hand off the path.
5. If it is pre-existing or grandfathered, confirm with the AHJ and treat any required correction as a new scope.
6. If the permit scope was misread, ask the AHJ to clarify in writing.
7. Flag any genuine hazard in writing regardless of ownership.

The judgment to bank: you do not win this by being defensive or by being a pushover. You win it with the notice, your contract, and a calm hand-off of what is not yours.
