What a Home Inspection Actually Catches (And What It Doesn't)

Most buyers assume a home inspection is a full, top-to-bottom guarantee that nothing's wrong with the house. It isn't, and knowing exactly where that line sits is what actually protects you during your inspection period.

What a standard inspection covers

A home inspector does a visual walkthrough of the home's major systems and structure: the roof, foundation, exterior, attic, electrical panel, plumbing, HVAC, and structural components. They'll run faucets, flip breakers, and test what's accessible, and hand you a report, usually within a day or two, flagging anything that's damaged, unsafe, or nearing the end of its life.

The gaps that catch buyers off guard

A few of these are worth calling out specifically, since they're easy to assume are covered when they're not:

• Pests and termites: this requires a separate wood-destroying insect (WDI) inspection. It's often required anyway for VA and FHA loans, so it's worth asking for even on a conventional loan.
• Septic and sewer lines: inspectors will run water and flush toilets to listen for obvious problems, but they won't scope the line with a camera. On older homes, a separate sewer scope is genuinely worth the money.
• Mold, radon, and lead: these need licensed specialists and lab testing, not a general inspector's visual check.
• Code compliance: inspectors flag safety concerns, but they aren't code enforcement, so an addition or renovation could be non-compliant without it showing up in the report.
• Future lifespan: a working furnace or water heater today doesn't come with a prediction of how many years it has left.

What this means for you as a buyer

None of this is a reason to skip an inspection, it's still one of the most valuable things you'll do before closing. It just means knowing when to bring in a specialist: a sewer scope on an older home, a WDI inspection in termite-prone areas, or a radon test if the inspector flags a reason for concern. Your inspection contingency is there to give you room to ask, negotiate, or walk away if something significant turns up.

If you're not sure which extra inspections make sense for a specific property, that's exactly the kind of thing worth asking before you're standing in the driveway on inspection day.
