California Home Seller Disclosure Requirements

California has the most comprehensive home seller disclosure regime in the United States. This page walks through every form a California seller of 1-to-4 unit residential property is required to deliver, the legal basis for each, and what happens if you don't.

This is general information, not legal advice. California disclosure law is enforced by statute and case law, and the consequences of skipping a disclosure can include rescission of the sale, lawsuits, and personal liability. Work with a real estate attorney or licensed broker on any specific situation.

The two required state forms (TDS and NHD)

Two forms are required by California state law for virtually every residential resale of a 1-to-4 unit property:

1. Transfer Disclosure Statement (TDS)

Required by California Civil Code sections 1102 through 1102.14. The TDS is the central seller disclosure document. It covers:

• Major appliances included in the sale and their condition.
• Structural components: roof, walls, foundation, floors, ceilings, windows.
• Room additions, alterations, and any work done without permits.
• Damage history: flooding, drainage, slope, fire, earthquake, settlement.
• Neighborhood nuisances: noise, odors, smoke, agricultural operations.
• Common interest development information if applicable.
• Any other known material facts affecting value or desirability.

Critical detail: the seller must personally complete the TDS. The listing agent cannot fill it out for the seller. The agent's job is to deliver it and document the delivery.

2. Natural Hazard Disclosure (NHD)

Required by Civil Code 1103. The NHD identifies whether the property sits in any of six specifically designated hazard zones:

• Special Flood Hazard Area (FEMA-designated).
• Area of Potential Flooding (dam inundation zone).
• Very High Fire Hazard Severity Zone.
• Wildland Fire Area (state responsibility area).
• Earthquake Fault Zone (Alquist-Priolo).
• Seismic Hazard Zone (liquefaction or landslide risk).

California is the only state in the country that requires this specific six-zone disclosure. Most sellers buy a Natural Hazard Disclosure Report from a third-party provider (about $100 to $150) which compiles all six zones automatically; doing it manually is possible but error-prone.

Additional required disclosures

Lead-Based Paint Disclosure (federal, but California-specific notes)

Federal law (42 USC 4852d) requires lead-based paint disclosure for any home built before 1978. The form must be signed by the seller and acknowledged by the buyer, and buyers get a 10-day inspection period. California enforces this aggressively because of the state's large pre-1978 housing stock.

Megan's Law Database Notice

Civil Code 2079.10a requires the listing agent to provide a written notice that registered sex offender information is available at the California Department of Justice's Megan's Law website. The notice itself is required; checking the database is the buyer's responsibility.

Mello-Roos Disclosure

If the property is in a Community Facilities District subject to a Mello-Roos special tax (Civil Code 1102.6b), the seller must disclose the existence of the tax and provide information about the assessed amount. Common in newer suburban developments built since the 1980s.

Earthquake Safety Disclosure

For properties built before 1960 (specific older construction types), the seller must provide the booklet "The Homeowner's Guide to Earthquake Safety" along with the disclosure form within it.

Water-Conserving Plumbing Fixtures

Civil Code 1101.5 requires disclosure of compliance with water-conserving plumbing fixture requirements (low-flow toilets and showerheads). Properties built or substantially renovated after 1994 generally comply; older properties may not.

Carbon Monoxide and Smoke Detector Compliance

State law requires properly functioning smoke detectors and, for properties with gas appliances or attached garages, carbon monoxide detectors. Disclosure of compliance is standard.

Delivery requirements and timing

Most state-required disclosures (TDS, NHD, lead paint) must be delivered to the buyer before acceptance of the purchase offer. If delivered after acceptance:

• Buyer has 3 days to terminate the contract if delivered in person.
• Buyer has 5 days to terminate if delivered by mail.
• The termination right runs from the date of delivery.

This is why standard California real estate contracts specifically reference disclosure delivery timing. Most agents deliver the TDS and NHD as soon as the listing goes live to avoid creating buyer rescission rights post-acceptance.

What happens if you don't disclose

California courts take seller disclosure obligations seriously. The consequences scale with the materiality of the omission and the seller's knowledge:

• Rescission of the sale: a successful claim can force the seller to unwind the transaction and buy the home back, often months or years after closing.
• Damages: actual cost to repair the undisclosed condition, plus consequential damages like temporary relocation expenses.
• Punitive damages: available where the seller fraudulently concealed a known defect.
• Attorney's fees: standard California real estate contracts include fee-shifting clauses. The losing side often pays both sides' legal costs.
• Personal liability: California's disclosure laws can pierce LLC and trust structures in fraud cases. Selling through an entity does not always protect individual sellers from liability.

The statute of limitations on most disclosure claims runs from when the defect was discovered, not when the home was sold. Sellers can be sued years after closing if the buyer later discovers an undisclosed condition the seller knew about.

The disclosure folder you should build before listing

California sellers who walk into the listing process with documentation already organized have a substantially smoother transaction. Items to gather:

• Permit records for every renovation, addition, deck, or finished basement.
• Receipts for major repairs (roof, HVAC, water heater, electrical, plumbing).
• Engineer reports for any structural or foundation work.
• Pest control history, especially termite treatment records.
• Any insurance claims filed on the property.
• HOA documents if applicable, including current bylaws and recent meeting minutes.
• Earthquake retrofit documentation if any seismic work was done.
• Water heater strap and earthquake bracing documentation.
• Compliance documentation for water-conserving fixtures if applicable.

How agents typically handle disclosures

Most California listing agents use a standard disclosure packet that bundles the required state forms with their own broker-specific addenda. Common additions to the state requirements:

• Seller Property Questionnaire (SPQ), a broader supplemental disclosure.
• Statewide Buyer and Seller Advisory (SBSA), covering general market conditions.
• Brokerage-specific advisories on environmental conditions, neighborhood considerations, and similar topics.

The SPQ in particular is widely used because it gives sellers a structured prompt to disclose items they might not think to volunteer on the TDS alone. Many California attorneys advise sellers to err on the side of over-disclosure, since the cost of disclosing too much is near-zero while the cost of disclosing too little can be a five-or-six-figure judgment.

The bottom line for California sellers

California disclosure law is built on a single principle: if you knew about it, you have to tell the buyer. The state forms are the structured floor. Honest answers and complete documentation are the actual standard.

Build the record while you own the home, keep every receipt and permit, and you walk into the listing process with most of what you need already organized. Documentation consistently saves sellers more money in disclosure compliance and avoided post-sale litigation than any other pre-listing investment.
