California Seller Disclosures Explained: What You Have to Disclose (and What Happens If You Do Not)
Selling a home in California comes with a legal obligation most sellers underestimate: telling the buyer the truth about the property.
What is the truth? How much to do share? How do you share it? These are the questions sellers ask themselves all the time and often have no idea how to answer these questions without putting themself at risk for a potential non-disclosure claim by a buyer.
Disclosure is where sellers get into the most legal trouble after closing. The roof leak you “forgot.” The neighbor dispute you hoped would not come up. The unpermitted bathroom you figured nobody would notice. These are the things that turn into demand letters and lawsuits a year after you have moved on with your life. This post walks through what California disclosure law actually requires, the forms you will be filling out, the gray areas that trip sellers up, and how to protect yourself whether you are selling with an agent or on your own.
The Legal Standard: Known Material Facts
California law requires sellers of residential property to disclose known material facts that affect the value or desirability of the property. And “material” is interpreted broadly. The practical test is simple: if a reasonable buyer would want to know it before buying, disclose it.
Notice the word “known.” You disclose what you know. You are not required to hire inspectors, climb into the crawl space, or guarantee the condition of the home. The law does not punish honest ignorance. What it punishes is concealment, and it punishes a very specific kind of strategic ignorance too: you cannot carefully avoid confirming a problem so that you can later say you never technically knew. If the ceiling stain appeared after the last big rain, “I never had it looked at” is not the shield people think it is.
And then there is the “as is” myth, which deserves its own paragraph because it costs sellers real money every year. Selling as is means you are not agreeing to make repairs. That is all it means. It does not mean the buyer takes the house blind, and it absolutely does not mean you can stay quiet about known problems. In California, an as-is sale with full disclosure is perfectly legal. An as-is sale used to hide a known defect is a lawsuit with a delay timer on it.
The Disclosure Documents You Will Be Filling Out
The Transfer Disclosure Statement, or TDS, is the core California disclosure form required in most residential sales. It walks through the condition of the property room by room and system by system: appliances, roof, plumbing, electrical, foundation, additions, modifications, and a long list of “are you aware of” questions covering everything from easements to neighborhood noise. Here is something a lot of people do not realize: the TDS generally cannot be waived, even in a for sale by owner transaction, even if the buyer says they do not care. The legislature made it mandatory precisely so that nobody could pressure anybody into skipping it.
The Seller Property Questionnaire digs deeper into the property’s history. Insurance claims you have filed, repairs you have made, disputes with neighbors, lawsuits involving the property, deaths on the property, and other facts a buyer would care about. Where the TDS asks about the house, the SPQ asks about the house’s story.
The Natural Hazard Disclosure reports whether the property sits in mapped hazard zones: flood zones, very high fire hazard severity zones, earthquake fault zones, seismic hazard zones, and more. A third-party company usually prepares this report for a modest fee, and in fire-prone parts of California, buyers and their insurers read it very carefully these days.
Depending on your property and your city, you may also have lead-based paint disclosures for homes built before 1978, smoke detector and water heater bracing compliance statements, HOA document packages with their own statutory delivery rules, septic and well disclosures, and local point-of-sale requirements that vary city by city. The full stack of paperwork is bigger than most sellers expect, and every page of it exists because somebody, somewhere, once got burned.
Selling without an agent? Every single one of these obligations still applies, and you are the one responsible for meeting them. FSBO sellers save the commission but carry the full disclosure burden alone, which is why we wrote a full guide onselling your home without an agent in California later in this series.
What You Must Disclose (The List Sellers Wish Was Shorter)
When known, sellers should disclose things like roof leaks and plumbing problems, foundation movement and drainage issues, water intrusion and past flooding, mold you know about, pest damage and past infestations, and fire or smoke damage. Past problems count even if they were repaired. The correct move with a repaired problem is to disclose both the problem and the repair, with documentation if you have it. A documented repair is a selling point. A hidden one is a liability.
Beyond the physical house, disclose unpermitted additions or work done without final permits, boundary disputes and encroachments, easements you are aware of, shared driveway or fence arrangements, deaths on the property within the past three years, insurance claims, and known neighborhood issues like a barking dog war, planned construction next door, or the band that practices in the garage two houses down every Saturday. Yes, courts have treated persistent neighborhood nuisances as material.
When in doubt, the rule is simple: disclose. A disclosed defect is a negotiating point that might cost you a few thousand dollars in a credit. A concealed defect is a lawsuit that can cost you the repair, the legal fees, and in cases of intentional concealment, much more. There is no version of this where hiding the problem is the financially smart move.
What Happens If You Do Not Disclose
Failure to disclose in California carries real consequences. A buyer who discovers a concealed defect can seek damages for the cost of repairs and the diminished value of the property. Where the concealment was intentional, the exposure climbs, and in serious cases a buyer can seek to unwind the entire sale. Add attorney fees, expert costs, and the months of your life the dispute will consume, and the math gets ugly fast.
And here is the part sellers consistently underestimate: these claims show up late. The buyer moves in, the first heavy rain arrives in December, the ceiling stain blooms, and the contractor they call says “oh yeah, this has been leaking for years.” Now the questions start. Who knew what, and when? The paper trail usually exists. Contractor invoices, insurance claims, emails with neighbors, permit records, even your old listing photos. “I did not know” is a hard argument to make against your own documents.
One more thing worth knowing: your liability does not transfer to your agent. Sellers sometimes assume that if the agent handled the paperwork, the agent owns the problem. Agents have their own duties, but the disclosure obligations belong to you, and you are the one signing the forms.
How to Protect Yourself as a Seller
Fill out your disclosure forms completely, honestly, and in your own words. Do not copy vague language from somewhere on the internet, and do not answer “unknown” to questions you actually know the answer to. Specific, plain-language disclosure is your best protection: “roof leaked at the chimney flashing in 2023, repaired by ABC Roofing, invoice available” is a fortress compared to a checked box.
Keep copies of everything you provide and a record of when you provided it. Disclosure timing matters because buyers have rights tied to when they receive certain forms. Late disclosure of something significant can give a buyer leverage, or an exit, at the worst possible moment in your escrow.
And if something feels gray, get legal advice before deciding to leave it off. An attorney review of your disclosure package before it goes out is one of the cheapest insurance policies in real estate, and it is a core part of the real estate services we provide to California sellers. It costs a fraction of what defending a failure-to-disclose claim costs after closing.
