What California sellers must disclose before a home sale
California law requires sellers to disclose known defects and hazard zones in writing before closing. Failing to disclose can trigger lawsuits for damages, rescission, and attorney fees.
When a California home sells, state law requires sellers to tell buyers about known problems with the property in writing before the sale closes. The Transfer Disclosure Statement is the main form, required by California Civil Code Section 1102 for sales of one to four residential units. Sellers must also disclose whether the property sits in hazard zones—flood areas, fire zones, earthquake fault areas, and others—on a separate Natural Hazard Disclosure form. Failing to disclose can expose sellers to lawsuits for rescission (where the buyer cancels and gets their money back), damages equal to the difference between the price paid and actual property value, and attorney fees. These liabilities exist even when buyers have inspected the property or signed "as is" agreements.
Certain sales are exempt: foreclosures, probate transfers, sales between family members or spouses, and court-ordered transfers do not require the TDS. But exempt or not, sellers have a deeper legal duty under California common law to disclose facts "known only to them" that materially affect property value. The state's "half-truth doctrine" means that making a partial statement while omitting qualifying facts counts as non-disclosure. Buyers who discover undisclosed defects have up to three years after closing to file a claim.
The Transfer Disclosure Statement and what it covers
The TDS is a statutory form prescribed by the California Legislature; sellers cannot create their own disclosure documents. The form requires answers "in good faith," defined by law as "honesty in fact in the conduct of the transaction." Sellers must disclose whether appliances, fixtures, and other systems work; any structural damage, water damage, or past repairs (even if completed); defects in major systems; shared driveways, boundary walls, and easement issues; soil issues such as fill or flooding; major damage from fire or earthquakes; zoning violations; neighborhood nuisances including traffic and noise; and HOA disputes or litigation.
Starting in 2026, two new disclosures were added. Assembly Bill 723 requires sellers to disclose if listing photography has been altered with artificial intelligence, and Assembly Bill 455 requires disclosure of tobacco or nicotine residue in the home. Brokers representing the seller must also complete their own section documenting observations from an independent inspection of the property, including "all facts materially affecting the value or desirability" that a reasonably competent inspection would reveal. Brokers face personal liability if they fail to conduct this inspection or if supervising officers fail to ensure compliance.
Timing and buyer rescission rights
California law requires TDS delivery "as soon as practicable before the transfer of title," typically within the first few days after the buyer makes an offer. The timing determines buyer protections. If the seller delivers the TDS before the buyer signs the purchase agreement, the buyer has no rescission right under Civil Code Section 1102.3. If the TDS arrives after the buyer has executed an offer, the buyer gains a powerful remedy: the right to cancel the purchase within three calendar days of personal delivery, or five calendar days if the disclosure is mailed or delivered electronically.
If the seller later amends the TDS because new information surfaces, the amendment restarts the buyer's rescission window from the date of the amended delivery, not from the original disclosure date. Many sellers strategically deliver disclosures before buyers sign offers to eliminate this three-day exit.
Natural hazard zones and separate disclosure
Special Flood Hazard Areas include zones designated by the Federal Emergency Management Agency with a 1 percent annual probability of flooding, plus areas subject to mudflows or flood-related erosion.
A seller must disclose if they know the property is in a hazard zone, or if it appears on local government lists posted at the county recorder, assessor, or planning offices.
Properties in recognized hazard zones often see reduced demand and lower property values. Buyers can argue that the lack of disclosure directly influenced their purchase decision, particularly if a natural disaster occurs and causes damage.
Consequences for sellers who don't disclose
Sellers who fail to disclose material facts can face rescission, where the buyer cancels the sale and receives a full refund. They can also face lawsuits for actual damages equal to the difference between the price paid and the property's actual value with undisclosed defects. In cases involving fraud—when the seller deliberately conceals information—buyers can recover punitive damages and attorney fees. California courts have held that "as is" sales and buyer home inspections do not protect sellers from liability for fraudulent misrepresentation of known, non-visible defects.
The statute of limitations is generous for buyers. Purchasers have up to three years after closing to file claims for non-disclosure. Real estate brokers and their supervising officers share this liability. If a broker's supervising officer fails to ensure that the broker properly inspects the property and discloses all material facts, the officer faces personal responsibility. The "half-truth doctrine" means a seller cannot make a partial statement that omits facts materially affecting the truth of what was stated.
“California courts have held that "as is" sales and buyer home inspections do not protect sellers from liability for fraudulent misrepresentation of known, non-visible defects.”
The broader disclosure duty beyond the form
Completing the statutory TDS form does not shield sellers from broader common-law fraud duties. Courts have held that sellers must disclose all material facts affecting property value, even if the statutory form is properly completed. A material fact is one that a reasonable buyer would consider important in deciding whether to purchase, or one that affects financing. For example, if a property is in a flood zone, the lender will likely require flood insurance, which affects the buyer's total cost of ownership.
Sellers must continue updating disclosures if they learn of new problems before the sale closes. Failure to amend disclosures when new issues emerge increases legal exposure. If a pipe bursts, a roof leak is discovered, or mold appears after the initial TDS is delivered but before closing, the seller must provide an amended disclosure. Each amendment restarts the buyer's three-day or five-day rescission period, giving buyers a fresh opportunity to walk away.
Exemptions and what they mean
Certain transactions are exempt from the TDS requirement entirely. Foreclosure and trustee's sales, probate sales by court order, transfers between spouses or relatives, and new subdivisions subject to state public report requirements do not require the form. However, many sellers in exempt transactions choose to provide disclosures voluntarily to reduce legal risk and signal transparency. Even in exempt transactions, sellers may still face liability under common-law fraud duties if they make affirmative misstatements or conceal known material defects.
Non-compliance with the TDS statute does not automatically invalidate a transaction. Violations do not unwind the sale; instead, the remedy is financial compensation to the buyer. However, this compensation can be substantial, and litigation costs mount quickly.
