The Truth, the Whole Truth: What You Legally Have to Disclose When Selling a Home

When you are selling your home, it is entirely natural to want to highlight its best features—the custom kitchen cabinetry, the sun-drenched patio, or the brand-new water heater. But what about the less-glamorous realities? The basement that gets a little damp during heavy spring rains, or the DIY deck renovation that you never quite got permitted?

Hiding these flaws is not just bad karma; it can lead to massive legal headaches, rescinded contracts, or expensive lawsuits well after you have handed over the keys.

Transparency is your best defense. Here is a breakdown of what you are legally and ethically obligated to disclose as a seller.

What is a “Material Defect”?

While disclosure laws vary significantly by state, the universal standard revolves around material defects. A material defect is a specific issue with a residential property that:

Has a significant adverse impact on the value of the property.
Poses a direct threat to the health or safety of its occupants.

You are generally only required to disclose issues within your personal knowledge. You do not need to hire a professional inspector to dig up hidden issues before you sell, but you must be entirely honest about what you already know.

The Common “Must-Disclose” Categories

Most state disclosure forms will explicitly ask you to check boxes or write explanations regarding the following areas:

1. Structural and System Failures

If it keeps the house standing, dry, or running, you have to talk about it.

The Big Three: Any known issues with the foundation (cracks, shifting), the roof (active leaks, missing shingles), or the basement/crawlspace (history of flooding or dampness).
Mechanical Systems: Faulty electrical wiring, aging or broken HVAC units, and chronic plumbing or sewer line backups.

2. Environmental & Health Hazards

Lead-Based Paint: This is the only federally mandated disclosure across all 50 states. If your home was built before 1978, you must provide a lead paint disclosure form.
Toxins: The known presence of radon gas, asbestos insulation, or toxic mold.

3. Pest Infestations

A past battle with critters isn’t necessarily a dealbreaker, but a current or history of wood-destroying insect activity (like termites or carpenter ants) must be documented, alongside any structural damage they left behind.

4. Legal, Boundary, and HOA Issues

Disclosures aren’t just physical; they are legal, too.

Property Lines: Active disputes with neighbors over where your driveway ends and theirs begins, or unpermitted fences built over property lines.
HOA Rules & Fees: If your home is in a managed community, you must disclose the existence of the Homeowners Association, their regular dues, and any upcoming “special assessments” (large, one-time fees for community repairs).
Unpermitted Work: If you remodeled your basement or added a bathroom without pulling local building permits, you need to state that clearly.

5. Neighborhood Nuisances

Is your home directly under a major commercial flight path? Is there a landfill a quarter-mile away that smells during hot summer days? If there is a persistent, significant local nuisance, many states require you to note it.

What About “Stigmatized” Properties?

One of the most frequent questions sellers ask is: “Do I have to disclose if someone died in the house?”

This is highly dependent on local laws. Some states require you to disclose a murder or suicide if it occurred within a certain timeframe (e.g., three years). Other states do not consider a death to be a material defect affecting the physical structure and explicitly state you do not have to disclose it unless asked directly. Pro-tip: If a buyer asks you point-blank, never lie.

When in Doubt, Disclose It

Sellers often worry that being too honest will scare buyers away. In reality, the opposite is true.

When a buyer sees a thoroughly filled-out disclosure form detailing past repairs (complete with receipts showing they were fixed by a professional), it actually builds trust. It shows you have cared for the property. On the flip side, trying to cover up a known issue is a ticking financial time bomb.

If you are staring at a disclosure form wondering, “Should I mention this?”—the answer is almost always yes.
