If a California seller knows about a material property defect, the seller usually must disclose it before closing. A buyer’s inspection does not excuse a seller’s silence. An “as-is” sale does not allow a seller to conceal known defects. And if the undisclosed issue affects value, safety, desirability, or use, the buyer may have claims for fraud, concealment, negligent misrepresentation, breach of contract, rescission, damages, and in serious cases punitive damages.
The key issue is usually not just whether the property had a problem. The key issue is whether the seller knew about the problem, whether it was material, whether it was disclosed, and whether the buyer suffered damages because of the omission.
California sellers must disclose known material facts
California Civil Code section 1102 requires sellers of most residential real property to provide statutory transfer disclosures to the buyer. The Transfer Disclosure Statement, often called the TDS, is the central disclosure form in many California residential transactions.
The seller’s duty is not limited to obvious or catastrophic defects. A seller must disclose known material facts that affect the property’s value, desirability, safety, or intended use. This can include water intrusion, mold, roof leaks, drainage problems, foundation movement, plumbing failures, electrical problems, structural issues, unpermitted work, code violations, easement disputes, boundary disputes, and other facts a reasonable buyer would want to know before closing.
California courts have long recognized that material property facts cannot be hidden from a buyer when those facts are known to the seller and not reasonably known to the buyer. The point of the disclosure rules is simple: the buyer should not be forced to purchase a property based on incomplete or misleading information.
The TDS must be accurate, complete, and updated when necessary
The TDS should not be treated as routine escrow paperwork. It is a legal disclosure document. A seller who gives vague, incomplete, or misleading answers may still face liability even if every box on the form was technically filled out.
A seller also should not assume that the buyer’s inspection shifts the burden away from the seller. If the seller knows about a material condition, the safer course is to disclose it clearly and in writing. A buyer’s inspector may miss hidden water damage, concealed mold, prior roof leaks, past foundation movement, or unpermitted work. The seller’s knowledge still matters.
If new information comes up before closing, the seller may need to update the disclosures. California Civil Code section 1102.3 addresses delivery of the disclosure statement and the buyer’s statutory cancellation rights. Late or amended disclosures can affect whether the buyer wants to proceed, renegotiate, request repairs, or cancel.
“As-is” does not mean “say nothing”
Many sellers believe that selling a property “as-is” eliminates disclosure obligations. That is wrong.
Civil Code section 1102 makes clear that waiver of statutory disclosure requirements is void as against public policy, and the delivery of the TDS may not be waived in an “as-is” sale. In practical terms, an as-is clause may limit repair obligations, but it does not give the seller permission to hide known material defects.
An as-is sale usually means the seller is not agreeing to fix every issue. It does not mean the buyer accepts defects the seller knew about but failed to disclose.
Common failure-to-disclose claims after closing
Most nondisclosure disputes involve recurring categories of property problems.
Water intrusion is one of the most common. Prior leaks, roof failures, window leaks, plumbing backups, drainage defects, mold, moisture staining, and wood rot can become serious claims if the seller knew about the condition and failed to disclose it.
Foundation and structural issues are also heavily litigated. Prior engineering reports, hillside movement, settlement cracks, retaining wall problems, soil movement, drainage corrections, or foundation repairs may need to be disclosed.
Unpermitted work can create major exposure. Buyers may inherit the cost of legalizing, correcting, or removing work that was not properly permitted. Sellers who performed unpermitted work, or who knew prior owners performed unpermitted work, should treat that information as important.
Non-physical issues can also be material. Boundary disputes, easement disputes, neighbor conflicts, code enforcement actions, pending litigation, HOA restrictions, rental restrictions, or occupancy problems may all affect value, desirability, or use.
Seller liability often turns on knowledge
A buyer does not win a nondisclosure claim simply by proving the property had a defect. The buyer usually needs to show that the seller knew about the material condition and failed to disclose it.
That knowledge can be proven directly or circumstantially. Useful evidence may include prior inspection reports, contractor invoices, insurance claims, text messages, emails, permit records, photographs, repair receipts, HOA records, neighbor statements, prior listings, and communications during escrow.
Seller nondisclosure cases often turn on whether the seller’s claimed lack of knowledge is believable. For example, a seller who lived with repeated water leaks, hired contractors, made insurance claims, or painted over visible damage may have difficulty arguing they knew nothing.
Real estate agents may also have disclosure duties
Sellers are not the only parties who may face liability. California Civil Code section 2079 requires covered residential brokers and salespersons to conduct a reasonably competent and diligent visual inspection of certain residential properties and disclose facts materially affecting value or desirability that the inspection would reveal.
Easton v. Strassburger is the leading California case behind this broker inspection and disclosure duty. The case recognized that real estate professionals may have disclosure obligations when material facts affecting the property are known or should be discovered through a reasonable inspection.
Agents can also face exposure based on what they actually knew, what they observed, what they were told, and what they represented during the transaction. Depending on the facts, a claim may involve the seller, listing agent, buyer’s agent, broker, inspector, contractor, or other transaction participants.
Buyer claims and remedies after closing
A buyer who discovers an undisclosed material condition after closing may have several possible claims, including fraud, concealment, negligent misrepresentation, breach of contract, rescission, and statutory disclosure claims.
The available remedies depend on the facts. A buyer may seek repair costs, diminished value, investigation costs, relocation expenses, loss of use, consequential damages, rescission, attorney’s fees if recoverable by contract or statute, and punitive damages where intentional fraud can be proven.
Rescission is not always practical, especially if the buyer has already moved in, repaired the property, refinanced, or made major changes. In many cases, the more realistic claim is for damages based on repair costs, loss in value, or other financial harm caused by the nondisclosure.
What buyers should do after discovering a defect
A buyer who discovers a serious issue after closing should preserve evidence before making major repairs. Photograph the condition, keep damaged materials if possible, obtain contractor reports, request permit records, collect disclosure documents, and organize escrow communications.
Do not rely only on verbal conversations. The strongest cases are usually document-driven.
The main questions are: What is the defect? When did it begin? Who knew about it? Was it disclosed? Would a reasonable buyer have cared? What did it cost to investigate, repair, or correct? Did the condition reduce the property’s value?
Those questions usually drive the legal claim.
What sellers should do before listing
Sellers should disclose known material issues clearly and in writing. If there is uncertainty, the safer approach is usually to disclose enough information to avoid creating a misleading impression.
Prior repairs should not be hidden. If a seller had significant water damage, mold remediation, roof leaks, drainage work, foundation movement, plumbing failures, electrical repairs, structural repairs, insurance claims, or unpermitted construction, the seller should not assume the issue disappeared because repairs were made.
A complete disclosure is usually less risky than a clean-looking disclosure that omits material history.
Frequently asked questions
What counts as a material defect in California?
A material defect is a condition a reasonable buyer would want to know before buying, negotiating price, removing contingencies, or deciding whether to proceed. This can include water intrusion, mold, foundation problems, roof defects, drainage issues, unpermitted work, electrical problems, plumbing failures, code violations, easement disputes, boundary disputes, and other issues affecting value, safety, desirability, or use.
Can a buyer sue after closing for failure to disclose?
Yes. A buyer may sue after closing if the seller failed to disclose a known material fact. Possible claims include fraud, concealment, negligent misrepresentation, breach of contract, rescission, and statutory disclosure claims. The strength of the case depends on proof of knowledge, materiality, reliance, and damages.
Does an as-is sale protect the seller?
Not from known nondisclosure. An as-is clause may limit repair obligations, but it does not allow a seller to conceal known material facts. Civil Code section 1102 does not allow the statutory TDS requirement to be waived simply because the property is sold as-is.
Does the seller have to disclose past repairs?
Often, yes. Past repairs can be material if they relate to significant conditions such as water intrusion, mold, foundation movement, roof leaks, plumbing failures, electrical problems, structural issues, drainage problems, or unpermitted work. A prior repair may matter because it tells the buyer about the property’s history and risk.
What if the seller says they did not know about the defect?
Lack of knowledge is a common defense. But the issue is fact-specific. Courts may consider repair history, prior complaints, contractor records, insurance claims, visible symptoms, communications, and whether the seller’s denial is credible. Many nondisclosure cases turn on circumstantial evidence of knowledge.
Can the real estate agent be liable too?
Possibly. Under Civil Code section 2079, covered residential agents and brokers have a duty to conduct a reasonably competent and diligent visual inspection and disclose material facts affecting value or desirability that the inspection would reveal. Agent liability depends on what the agent knew, saw, should have disclosed, and represented during the transaction.
How long does a buyer have to bring a claim?
The deadline depends on the claim and when the buyer discovered or reasonably should have discovered the problem. Fraud, contract, negligence, and statutory claims may have different deadlines. Buyers should get legal advice quickly because delay can affect both the statute of limitations and the quality of the evidence.
Bottom line
California sellers must disclose known material facts. Buyers do not have to absorb losses caused by concealed defects simply because the problem was discovered after closing. But these cases are evidence-driven. The outcome usually depends on what the seller knew, what was disclosed, what the buyer relied on, and what damages resulted.
