The Inspection Passed but You Know Something Is Wrong: Decision Tree

Why this matters

A passed inspection feels like permission to move on. But an inspector can miss things, and a green sticker does not make an unsafe install safe. When your gut and the paperwork disagree, the paperwork is not the tiebreaker. A sticker does not carry current, hold pressure, or vent combustion; the work does. This tree is for the moment the inspection passed and you still know something is not right.

Start here: is it an immediate safety hazard?

Before you weigh anything else, handle danger:

• If the defect is an active hazard (a gas connection that could leak, a bond or ground that is not there, a flue that could spill combustion products, a connection that could overheat), correct it or make it safe now, regardless of the pass. A passed inspection is not authorization to leave a hazard in place.
• If you cannot make it safe on the spot, do not leave it energized, pressurized, or in service. Isolate it and tell the customer plainly why.

The pass protects the paperwork. It does not protect the people who live with the work.

If it is your own work

You do not get to hide behind the inspector's miss. If you know your install has a real defect, you fix it, pass or no pass. The inspection is a check on your work, not a substitute for doing it right. Correcting your own known defect quietly and properly is cheaper than the callback, the failure, or the liability when it surfaces later.

If it is a genuine safety defect the inspector missed

Sometimes the miss is on work in the system that is now yours to stand behind:

• Correct it. A missed hazard is still a hazard. The fact that it passed changes the paperwork, not the physics.
• Document what you found and what you did, with photos. If it ever surfaces, your record shows you caught and corrected it rather than covered it.
• Do not rely on the pass as a defense. "It passed inspection" has never made a failed gas connection or a missing ground safe, and it will not protect you when the consequence lands.

If it is a code miss but not a hazard

Not every miss is dangerous. A non-hazard code deviation is a judgment call:

• If you touched it or it is inside your scope, correct it. Leaving a known code miss on your own work invites the next inspector, buyer, or contractor to find it.
• If it is outside your scope and not a hazard, disclose it in writing and note that it is pre-existing and not part of your work. You are not obligated to rebuild the whole property, but you do not stay silent either.
• When unsure whether it is a hazard, treat it as one until you can rule it out.

If it is someone else's work in the same system

Unpermitted or substandard prior work that passed alongside yours is not something you certify by association:

• Draw a written scope boundary: your work ends here; the existing work beyond is pre-existing and not evaluated or modified by you.
• Do not vouch for it just because the inspection covered the visit. You attest to what you did and can verify, nothing more.

Should you tell the inspector?

Usually you handle the fix and move on. Raise it with the authority having jurisdiction (the AHJ, the local building official) when the miss is systemic or repeatable: an inspector consistently passing a genuinely dangerous condition is a pattern worth a professional, factual heads-up, not to embarrass anyone but because the next house gets the same miss. Keep it about the condition and the code, never personal.

Recap

1. Hazard first: correct it or take it out of service, pass or not.
2. Your own work: fix a known defect regardless of the sticker.
3. Missed safety defect you inherit: correct, document, do not lean on the pass.
4. Non-hazard code miss: correct what you touched, disclose what you did not.
5. Someone else's work: scope boundary in writing, certify nothing you cannot verify.
