Major Defect

When buyers, agents, and inspectors talk about a "major defect," they generally mean a significant problem with a property that goes beyond routine maintenance or ordinary wear: something that affects how the home functions, whether it's safe to occupy, its structural integrity, or its overall value.

Common examples of what people typically describe as major defects include: significant structural concerns (foundation movement, compromised framing), safety hazards (electrical systems in dangerous condition, failing heating equipment), major system failures (roof at or beyond the end of its service life, HVAC not functioning), and evidence of significant moisture intrusion or water damage.

What's important to understand: there is no single universal definition of "major defect" that applies to every home, every inspection, every contract, or every jurisdiction. The term is often used informally to distinguish problems that require serious attention from routine maintenance items, but severity, context, and what's appropriate to do about a finding depend on the specific situation.

Not all inspection findings carry equal weight. Identifying which findings in an inspection report represent significant concerns, as opposed to maintenance items, deferred upkeep, or ordinary wear, is one of the most important skills a buyer can develop when reviewing the report.

Major defects matter because they:

- May affect the safety of the home's occupants - Can be costly to repair, sometimes significantly so - May raise questions about whether the property was properly maintained or disclosed - May change how a buyer thinks about the transaction, such as whether to proceed, renegotiate, or seek further evaluation

Finding a significant defect during an inspection does not automatically mean a transaction must end. Buyers typically have options: requesting repairs, asking for a credit or concession, seeking specialist evaluation to understand the full scope and cost, or, depending on the contract, renegotiating terms. The right response depends on the specific finding, the contract, the market, and the buyer's own situation and priorities.

When an inspector notes a concern and recommends evaluation by a specialist (a structural engineer, an electrician, a roofer), that recommendation is meaningful. Getting that follow-up evaluation is the appropriate way to understand whether a finding rises to the level of a major defect and what addressing it would involve.

During a home inspection, the inspector observes what appears to be significant settling in the crawl space and recommends evaluation by a structural engineer. The buyer arranges for a licensed structural engineer to visit the property. The engineer provides an assessment of the extent of the movement, whether it is active or historical, and what remediation, if any, may be appropriate. The buyer then reviews the engineer's report with their agent to decide how to proceed within the inspection period.

"Every defect found during an inspection is a major defect."

Inspections routinely identify a wide range of conditions, from safety hazards and significant system failures to minor maintenance items, cosmetic wear, and conditions that are simply normal for a home of that age and type.

A door that doesn't latch properly, worn weatherstripping, a missing GFCI outlet, or a water heater nearing the end of its typical service life are all things an inspector may document. They are not the same as a failing foundation, a compromised electrical panel, or significant structural movement. Understanding the difference between findings that require prompt, serious attention and those that reflect routine maintenance is essential to making informed decisions about an inspection report.

When unsure how to weigh a specific finding, ask the inspector to explain it, and where the inspector has recommended specialist follow-up, get that evaluation before drawing conclusions.
