California Real Estate Disclosures Explained

California has the most comprehensive seller disclosure requirements in the United States — and it is the only state requiring a Natural Hazard Disclosure report. Getting this wrong creates liability that survives the closing by years. Here is every required form, what you must disclose, and the buyer's right to walk away after receiving it.

What Disclosures Are Required in California?

California disclosure is layered. At the bottom sits a statutory floor the legislature requires on every 1-4 unit residential transfer. Above that sit contractual and local disclosures that vary by property and county.

FormAuthorityApplies To
Transfer Disclosure Statement (TDS)Civil Code 1102 - 1102.17Every 1-4 unit residential transfer
Natural Hazard Disclosure (NHD)Civil Code 1103Every residential transfer
Lead-based paint disclosureFederalHomes built before 1978
Megan's Law noticeCivil Code 2079.10aEvery residential transfer
Mello-Roos / special assessmentCivil Code 1102.6bProperties in special tax districts
HOA document packageCivil Code 4525Common interest developments
Water heater and smoke alarm complianceHealth & Safety CodeMost residential transfers

Selling "as-is" does not waive any of this. Civil Code 1102 applies regardless, and any attempted waiver of the disclosure requirement is void as against public policy. As-is means you will not make repairs. It does not mean you can withhold what you know.

What Is the Transfer Disclosure Statement?

The TDS is California's central disclosure form. The legislature wrote the exact language, and the seller must complete it personally — an agent cannot fill it out for you.

You disclose, to the best of your actual knowledge, material defects affecting the property's value or desirability. The form covers:

  • Built-in appliances and their working condition
  • Structural systems — foundation, roof, walls, windows
  • Roof leaks and prior insurance claims
  • Drainage, grading, soil and geological conditions
  • Room additions and whether they were permitted
  • Environmental hazards — lead paint, asbestos, radon, formaldehyde, fuel or chemical storage tanks, contaminated soil or water
  • Neighborhood noise and nuisances
  • Shared facilities, easements, and boundary disputes
  • HOA and common area conditions

Both the seller and each cooperating agent sign it, and agents add their own visual inspection observations separately.

Material facts extend beyond the building. A barking dog, a planned development next door, known criminal activity, or an unpermitted addition can all constitute material facts. The test is whether a reasonable buyer would consider it important — not whether it is physically part of the house.

The Natural Hazard Disclosure: Unique to California

California is the only state in the country that requires a Natural Hazard Disclosure. Under Civil Code 1103, you must disclose whether the property lies within any of six designated zones:

ZoneWhat It Means
Special Flood Hazard AreaFEMA-designated flood risk
Dam Inundation ZoneDownstream of a dam failure path
Very High Fire Hazard Severity ZoneState-designated wildfire risk
Wildland Fire AreaState fire responsibility area
Earthquake Fault ZoneAlquist-Priolo designated fault
Seismic Hazard ZoneLiquefaction or landslide risk

Third-party NHD companies prepare the report, and the seller customarily pays — though the cost is technically negotiable.

This matters enormously in Roman's service area. Large portions of the Ojai Valley, the San Bernardino mountain communities, and hillside areas across Los Angeles County fall into Very High Fire Hazard Severity Zones. That designation now affects not just disclosure but insurance availability — and a buyer who cannot bind coverage cannot close.

The Buyer's Right to Cancel After Disclosure

Delivering disclosures starts a clock. Under Civil Code 1102.13, a buyer may rescind the purchase agreement without penalty:

  • Three business days after personal delivery
  • Five days after delivery by mail

That window reopens if disclosures are materially amended after the contract is signed. If you discover a defect mid-escrow and amend the TDS, the buyer gets a fresh rescission right.

The practical implication for sellers: deliver disclosures early. The TDS is typically delivered within seven days of accepting an offer, and delivering promptly gets the rescission window running and behind you rather than hanging over the transaction.

What Happens If You Fail to Disclose?

This is where California disclosure stops being paperwork and becomes financial exposure that outlives the sale.

Buyers generally have three years from discovering a problem to bring a claim — not three years from closing. A defect that surfaces in year four is still actionable if the buyer only discovered it then.

RemedyWhat It Means
DamagesThe cost to repair what you failed to disclose
Attorney feesFrequently awarded to the buyer
RescissionThe sale is unwound — you return the purchase price

The uncomfortable arithmetic: you may have spent the proceeds, bought another home, and moved on. A rescission claim arriving three years later does not care about any of that.

The safest rule is the simplest one. If you are unsure whether something is material, disclose it. Over-disclosure has almost no downside — a buyer either accepts it or negotiates. Under-disclosure has a very large one. Sellers routinely worry that mentioning a past leak will scare buyers off; in practice a repaired, disclosed, documented leak is far less alarming than one a buyer's inspector finds that you did not mention.

Disclosures That Trip Up California Sellers

Unpermitted work

A converted garage, an added bathroom, an enclosed patio. If you know it was done without permits, disclose it. Buyers find out during appraisal or through county records anyway, and discovering it late looks like concealment even when it was oversight.

Prior insurance claims

The TDS asks. Claims history is also visible to buyers through CLUE reports, so a claim you omitted is one they can independently find.

Deaths on the property

Deaths within the past three years must be disclosed. California law specifically protects AIDS-related deaths — a seller may not disclose that an occupant had or died from AIDS.

Mello-Roos and special assessments

Properties in special tax districts require separate disclosure under Civil Code 1102.6b. This matters in newer master-planned communities — parts of Orange County, Harvest at Limoneira in Santa Paula, and much of the Inland Empire. Buyers who discover a $400 monthly assessment after removing contingencies are unhappy buyers.

Neighborhood conditions

Known material facts extend past your property line: a planned development, chronic noise, a problem neighbor, drainage from an adjacent lot. If you know it and a reasonable buyer would want to know it, it belongs on the form.

Who Prepares Your Disclosure Package?

This is where the choice of listing model has a concrete consequence, and it is worth understanding before you pick one.

ModelWho Assembles DisclosuresYour Exposure
Flat fee MLSYou doFull — no agent review
Discount / low commission brokerageVaries by brokerageConfirm in writing before signing
Full-service flat feeAgent prepares and reviews with youSame as a percentage agent
Traditional percentage agentAgent prepares and reviews with youStandard

A flat fee MLS service places your listing and stops. You complete the TDS, order the NHD, assemble the HOA package, and manage delivery timing — alone. For a straightforward property with a knowledgeable seller that can work. For a home with unpermitted work, a fire-zone designation, or a complicated HOA, it is where liability gets created.

Roman is a flat fee realtor, not a flat fee MLS service. The $7,250 or $9,250 covers full listing representation — including disclosure package preparation, review, and delivery timing — the same scope a 2.7% listing agent provides. A discount realtor or low commission realtor still charges a percentage; ask specifically what their fee includes here, because it varies.

Selling a property with disclosure complexity? Unpermitted work, fire zone, HOA, or Mello-Roos — Roman handles the package at a flat fee, not a percentage.

Frequently Asked Questions

What disclosures are required when selling a house in California?
At minimum: the Transfer Disclosure Statement (TDS) under Civil Code 1102, the Natural Hazard Disclosure (NHD) under Civil Code 1103, a lead-based paint disclosure for homes built before 1978, and the Megan's Law notice. Additional disclosures apply for Mello-Roos districts, HOA properties, well and septic systems, and certain local requirements.
What is the Transfer Disclosure Statement (TDS)?
California's central seller disclosure form, required by Civil Code 1102 through 1102.17 on every transfer of a 1-4 unit residential property. The seller discloses, to the best of their actual knowledge, material defects affecting the property's value or desirability -- appliances, structural systems, roof leaks, prior insurance claims, drainage, soil conditions, neighborhood noise, and more.
Can my agent fill out the TDS for me?
No. The seller must personally complete the TDS. An agent cannot fill it out on your behalf. Both the seller and the cooperating agents sign it, and each agent adds their own visual inspection observations.
Do I still have to disclose if I sell as-is?
Yes. Selling as-is does not waive California's disclosure obligations. Civil Code 1102 applies regardless, and any attempted waiver of the requirement is void as against public policy. As-is means you are not agreeing to make repairs -- it does not mean you can withhold what you know.
What is the Natural Hazard Disclosure and why is it unique to California?
California is the only state that requires it. Under Civil Code 1103, sellers must disclose whether the property lies within any of six designated zones: Special Flood Hazard Area, Dam Inundation Zone, Very High Fire Hazard Severity Zone, Wildland Fire Area, Earthquake Fault Zone, or Seismic Hazard Zone. Third-party companies prepare the report, and the seller customarily pays.
Can a buyer cancel after receiving disclosures?
Yes. Under Civil Code 1102.13, a buyer has three business days after personal delivery, or five days after delivery by mail, to rescind the purchase agreement without penalty. That window resets if disclosures are materially amended after the contract is signed.
What happens if I fail to disclose something?
Exposure is significant and long-lived. Buyers generally have three years from discovering the problem to file suit. Remedies can include damages equal to repair costs, attorney fees, and in serious cases rescission of the sale -- meaning you return the purchase price. A defect you concealed can surface years after you have spent the proceeds.
Does a death on the property have to be disclosed?
Deaths occurring on the property within the past three years must be disclosed. California law specifically protects AIDS-related deaths from this requirement, and a seller may not disclose that an occupant had or died from AIDS.
