Yes. If you’re selling a 1 to 4 unit residential property in California, state law requires you to complete specific disclosure forms, most importantly the Transfer Disclosure Statement (TDS) and the Natural Hazard Disclosure (NHD), before the sale closes. We tell every seller the same thing upfront: deliver these early, deliver them completely, and document that delivery, because late or incomplete disclosures give buyers a statutory right to walk away.
TL;DR:
- Providing complete disclosure forms, including the Transfer Disclosure Statement and Natural Hazard Disclosure, before the sale closes is crucial to avoid buyer rescission rights.
- Disclose only what you actually know about material defects, such as past leaks or unpermitted additions, with detailed explanations attached to clarify previous repairs or issues.
- Deliver disclosures “as soon as practicable,” ideally before the offer, and use timestamped electronic records to prevent rescission if sent late.
- Coordinate inspections like pest or roof reports early, share findings with your agent, and disclose neighborhood-specific issues proactively to build trust.
- Gather all permits, inspection reports, receipts, and relevant documents in advance, enabling quick, specific disclosures that protect you from future legal claims.

What Are the Disclosure Requirements in California for Home Sellers?
California Civil Code § 1102 et seq. sets the baseline: sellers of most 1 to 4 unit residential properties must provide written disclosures using standardized state forms, and the Transfer Disclosure Statement is the anchor document. Beyond the TDS, sellers typically owe buyers a Natural Hazard Disclosure, a Megan’s Law notice, and several situational notices depending on the property’s location and age.
The Transfer Disclosure Statement asks about the condition of major systems and structural components, roof age, known water intrusion, permit history, and any defects you’re aware of in appliances, plumbing, electrical, or foundation. You complete it personally, based on your actual knowledge, and you sign it. Your agent completes a separate section covering their visual inspection findings.
The Natural Hazard Disclosure covers flood zones, fire hazard severity zones, earthquake fault zones, and seismic hazard zones. Most sellers order this report through a third-party natural hazard disclosure company rather than researching each zone manually; escrow or your agent typically coordinates this. Delivering the NHD late can trigger the same rescission exposure as a late TDS, which we cover in more detail in our natural hazard disclosure guide.
Megan’s Law requires sellers to point buyers to the state’s official registry rather than provide offender details directly. A short standardized notice satisfies this.
Other notices come up depending on your property:
- Mello-Roos or special tax district notices, when the property sits inside an assessment district
- Supplemental property tax notices explaining reassessment after sale
- Lead-based paint disclosures for homes built before 1978
- Smoke detector and water heater bracing compliance statements
Your DRE consumer booklet walks through each of these in plain language, and it’s worth reading once even if your agent handles the paperwork.
What Counts as a Material Defect You Must Disclose?
California’s disclosure standard is narrower than most sellers assume: you disclose what you actually know, not what a hypothetical inspection might uncover. The statute doesn’t require you to hire an engineer before listing. It requires honesty about what you’re aware of.
Material defects generally include:
- A roof leak you patched three years ago, even if it hasn’t recurred
- Foundation cracks, past or present, structural or cosmetic
- Unpermitted additions or room conversions
- Past pest infestations, even if treated
- Neighbor disputes over boundaries, easements, or noise
Cosmetic wear, like scuffed paint or dated countertops, isn’t material. When in doubt, disclose and attach a brief explanatory note describing what happened and what you did about it.
Pro Tip: A one-sentence explanation attached to a “yes” answer, like “roof leak repaired in 2022, no recurrence,” protects you far better than a bare checkbox ever could.
When Must You Deliver Disclosures, and What Rights Does the Buyer Have?
California law expects disclosures delivered “as soon as practicable” before transfer of title. In practice, most Bay Area transactions deliver the TDS and NHD before the buyer’s offer is accepted, often as part of the listing packet, so the buyer reviews everything before writing an offer at all.
When disclosures arrive after the buyer has already signed a purchase agreement, Cal. Civ. §1102.3 gives the buyer a right to cancel:
- Three days to terminate if the disclosures were delivered in person
- Five days to terminate if delivered by mail or electronic transmission
- The clock resets if you issue a material amendment to those disclosures later, so avoid last-minute changes once the window has started
Electronic delivery through your transaction platform works, but keep a timestamped delivery record. Escrow officers rely on that documentation to confirm the rescission period has closed before scheduling your closing date.
Who Is Responsible: You or Your Agent?
Your listing agent carries an independent legal duty to conduct a reasonably competent visual inspection of accessible areas and disclose what they observe, separate from what you disclose yourself. This is often called the Agent Visual Inspection Disclosure, and it exists precisely because sellers sometimes miss things they’ve grown used to seeing every day.
Expert reports, structural pest inspections, roof certifications, electrical panel assessments, don’t just inform your answers. They shift liability. If a licensed inspector signs off on a system and something later fails, you and your agent are in a much stronger position than if you’d guessed.
- Order pest and roof reports early if the property is older or shows visible wear
- Share every report with your agent before the TDS is finalized, not after
- Ask your agent to walk the property with you and flag anything you might overlook
Pro Tip: If you’re unsure whether something is disclosable, ask your agent to review it against a recent inspection report rather than guessing. That single conversation resolves more disputes than any form ever will.
Which Local and Recently Updated Disclosures Should You Check?
Location drives a surprising share of your disclosure obligations, and recent statutory changes have added new ones. Sellers in Mello-Roos districts must make a good-faith effort to notify buyers of the special tax, usually by including the district’s own notice or directing buyers to the county assessor’s records.
Fire hazard rules matter across much of the East Bay hills and wildland-adjacent neighborhoods. Cal Fire’s ReadyForWildfire mapping tool shows whether a property sits in a high or very high fire hazard severity zone, and homes built before 2010 in those zones face additional retrofit and disclosure notices tied to defensible space and construction materials.
Starting January 1, 2026, sellers must include a statutory electrical advisory for many properties, encouraging buyers to have the electrical system inspected and flagging that older homes may carry insurance and fire risk tied to limited electrical capacity. This is separate from, and in addition to, the TDS’s existing electrical questions.
A related trigger applies to domestic water storage tanks in some jurisdictions, requiring specific written notice when a property relies on one.
Roughly 1 in 3 California addresses now falls within a mapped fire hazard zone under current Cal Fire data, which is one reason we tell Bay Area sellers to check the map before listing, not after an offer arrives.
Your Practical Seller Checklist for a Clean Disclosure Process
Getting through disclosure obligations smoothly comes down to sequencing. Gather documents before you list, not while you’re fielding offers.
- Pull permits for any past work, HOA documents and CC&Rs if applicable, Mello-Roos notices, and utility or insurance records
- Order pest, roof, or electrical inspection reports if the property is older or shows visible issues; the report cost is small compared to the liability protection it buys
- Compile dated photos and repair receipts for anything you disclose, so your explanatory notes have backup
- Coordinate with your listing agent and escrow officer on a delivery timeline that gets disclosures to buyers before they submit an offer whenever possible
- Flag neighborhood-specific issues honestly, hillside drainage patterns, known slope movement, or shared-driveway disputes common in parts of the Berkeley and Oakland hills
Pro Tip: If your property sits on a slope or near a known drainage easement, mention it even if you’ve never had a problem. Bay Area buyers and their inspectors look for exactly this, and disclosing it first builds trust instead of raising suspicion.
Our HOA document review checklist and escrow timeline guide both walk through the coordination steps in more detail if your sale involves either.
Official Forms, Statutes, and Hazard Maps Worth Bookmarking
Start with the primary sources rather than a summary of a summary. The DRE’s consumer booklet and its official TDS forms are the baseline reference. The statute text itself, Civil Code §1102 and §1102.3, governs timing and rescission rights.
For situational notices, check Megan’s Law and Cal Fire’s ReadyForWildfire maps directly rather than relying on secondhand summaries. Nolo’s plain-English overview is a useful bridge between statute and practice.
When a disclosure question is genuinely ambiguous, a short consultation with a real estate attorney is worth more than guessing.
Our Take: Why Statutory Compliance Alone Isn’t Enough
The statute gives you a floor, not a strategy. Cal. Civ. §1102 tells you what forms to complete and when, but it doesn’t tell you how to write a TDS answer that actually protects you if a buyer sues eighteen months after closing. That gap is where most sellers get exposed, not because they lied, but because they answered vaguely.
Conventional advice treats disclosure as a compliance checkbox: fill out the form, hand it over, move on. We think that undersells the value of specificity. A vague “yes” on a roof question is a liability. A dated, specific explanation with a repair receipt attached is a defense. The difference costs you ten extra minutes and saves you a potential dispute.
Prioritize this: gather your documentation before you list, not during escrow. Sellers who scramble for permits and receipts after an offer arrives lose negotiating leverage and delay closing. Sellers who show up with a complete, well-documented disclosure package close faster and face fewer post-sale surprises.
