Failure to Disclose a Home Defect in California: Seller Liability, Explained

Seller liability for nondisclosure, explained for sellers and the agents who advise them

In California, selling a home comes with one of the most demanding disclosure regimes in the country. Sellers are expected to tell buyers what they know about the property’s condition — and when they don’t, the consequences can follow them long after the sale closes. For real estate agents, understanding these rules is just as important: it’s how you protect your clients and yourself from liability claims.

Here’s a clear look at what California sellers must disclose, what happens when something is left out, and how disputes like an undisclosed pool leak typically play out.

The core rule: disclose known material defects

California Civil Code section 1102 and the sections that follow generally require sellers of residential property (one to four units), subject to specified exemptions, to deliver a completed Transfer Disclosure Statement, or “TDS,” to the buyer as soon as practicable before transfer of title. On that form, the seller discloses what they know about the property’s condition.

The TDS covers a wide range of items, including the condition of structural and mechanical components — roof, foundation, walls, floors, plumbing, and electrical systems — as well as known environmental hazards. Importantly, the law generally requires sellers to disclose defects they know about. It does not require them to tear open walls or commission inspections to discover problems they’re unaware of. The duty is honesty about what you know, not omniscience.

“As-is” does not mean “don’t ask, don’t tell”

One of the most common and costly misconceptions is that selling a home “as-is” removes the obligation to disclose. It doesn’t. Even in an as-is sale, a California seller still must disclose known material facts that affect the property’s value or desirability. The as-is clause shifts responsibility for repairs — it does not give a green light to hide a known problem.

Agents have duties too

Disclosure obligations don’t fall on sellers alone. Under California Civil Code § 2079, which codifies the visual-inspection duty recognized in Easton v. Strassburger, a real estate broker or agent generally must conduct a reasonably competent and diligent visual inspection of accessible areas of the property offered for sale and disclose to a prospective buyer all facts materially affecting the value or desirability of the property that the inspection would reveal. That’s why understanding disclosure law is a practical risk-management tool for agents — not just legal background.

What happens when a seller fails to disclose

A seller or agent who willfully or negligently fails to perform applicable disclosure duties may be liable for the actual damages the buyer suffers as a result. In practice, damages may include the cost to repair the undisclosed problem, although the available remedies and measure of damages depend on the facts and legal claims asserted. Disputes can also involve claims of misrepresentation or fraud, depending on the facts.

Many California purchase agreements include a mediation provision that may require the parties to attempt mediation before litigation or may affect a party’s ability to recover attorney’s fees, so a nondisclosure dispute may proceed to mediation through a provider such as JAMS before anyone sees the inside of a courtroom. Resolving these matters early, with experienced counsel, can often save both sides significant time and expense.

A typical situation (illustrative)

A buyer moved into a home with a backyard pool and soon noticed the water level kept dropping. Investigation revealed a leak in the pool — a condition the sellers may have known about before the sale but did not disclose on the TDS. If the purchase contract required mediation, the dispute could proceed to a JAMS mediation, where the parties might work toward a resolution concerning the alleged undisclosed defect.

Note: This example illustrates the kind of nondisclosure dispute we handle. It does not describe a specific client or outcome, and every matter is different.

How sellers and agents can protect themselves

• When in doubt, consider disclosing. If you’re unsure whether something is material or how to complete a disclosure form, consult your real estate professional or a qualified California attorney.
• Document the condition and any repairs. Keep records of known issues, inspections, invoices, and what was communicated to the buyer.
• Don’t rely on “as-is” as a shield. It does not excuse a failure to disclose a known defect.
• Agents: conduct the visual inspection required by law and document it. A diligent, documented walkthrough can help protect your clients and support compliance with your professional duties.
• Get advice early if a claim surfaces. Many disputes are far cheaper to resolve before they escalate.

Frequently asked questions

Do I have to disclose problems I already fixed?

A past defect can still be material — for example, prior water intrusion or a repaired structural issue. Whether disclosure is required depends on the facts, including what the seller knows and whether the condition materially affects value or desirability. An attorney can help you assess specific items.

I’m selling “as-is.” Do I still need a TDS?

Generally, yes, although statutory exemptions may apply. The as-is designation addresses who pays for repairs; it does not eliminate applicable duties to disclose known material facts on the TDS.

What can a buyer recover if a seller fails to disclose?

Potentially, actual damages caused by the nondisclosure, which may include the cost to repair the undisclosed condition. The available remedies and any additional claims depend on the facts and applicable law.

We have a dispute — do we have to go straight to court?

Often not. Many California purchase contracts include mediation provisions, and mediation may be required before litigation or may affect attorney’s-fee recovery. Many disclosure disputes are resolved through providers such as JAMS without a trial.
