2026 Update: California Seller Disclosures, AB 455 & Fast Sale Options

If you're selling a one to four unit home in California, you must complete a Transfer Disclosure Statement (TDS), deliver a Natural Hazard Disclosure (NHD) Statement, and, starting in 2026, disclose any known history of smoking or vaping on the property under AB 455, as required by state law. These documents must reach the buyer before the sale closes, and skipping them, or fudging what you know, can leave you exposed to a lawsuit long after you've handed over the keys.

TL;DR:

Sellers of single-family homes in California must disclose known issues including smoking or vaping history starting in 2026 under AB 455, even if odor is no longer present.

Completing the Transfer Disclosure Statement requires honest reporting of structural, environmental, and permit-related facts, with documentation supporting inspections or repairs.

The Natural Hazard Disclosure report must be current and precise, especially near hazard zone boundaries, to reduce potential liability.

Delays or omissions in delivering required disclosures can lead to legal disputes, canceled deals, or reopened negotiations, especially if late or incomplete.

Fully disclosing known hazards and property issues speeds up sales, reduces post-sale disputes, and builds buyer trust, even during fast or cash transactions.

What Are the Required Seller Disclosures in California?

Every seller needs a mental checklist before listing, because California disclosure requirements aren't optional paperwork. They're state law, and some apply no matter what kind of home you're selling while others depend on where the house sits or what's happened on the property.

Here's what shows up most often:

Transfer Disclosure Statement (TDS): covers known material facts about the property's condition, required for almost every 1 to 4 unit residential sale
Seller Property Questionnaire (SPQ): a companion form many brokers use to dig deeper into the history the TDS might not capture
Natural Hazard Disclosure (NHD) Statement: flags flood zones, fire zones, and seismic risk
Megan's Law notice: a standard statutory notice pointing buyers to the state's sex offender registry, not a requirement to investigate offenders yourself
Federal lead-based paint disclosure: required for any home built before 1978
Mello-Roos or Community Facilities District (CFD) notice: applies if the property carries a special tax assessment
Private Sewer Lateral (PSL) disclosure: required in certain cities with local sewer compliance ordinances
Meth lab cleanup notice: applies only if the property was subject to a contamination order
AB 455 thirdhand-smoke disclosure: new for 2026, applies if you know of a smoking or vaping history

Some of these apply to nearly every seller (TDS, NHD, Megan's Law notice). Others depend entirely on your address or your property's history. A condo in a Mello-Roos district faces a tax notice a single-family home two blocks away might never see. Local ordinances and HOA rules can pile on more forms, so a quick call to your title company or agent about city-specific requirements early in the process saves you from a surprise addition to your disclosure packet a week before closing.

Transfer Disclosure Statement: What Does It Require You to Disclose?

The TDS is the backbone of California's disclosure law, and Civil Code Section 1102 requires sellers of 1 to 4 unit residential properties to deliver it in writing as soon as practicable, before the transfer of title closes. If you own the home and you're the one selling it, you complete this form yourself. It isn't something your agent fills out on your behalf, though they'll guide you through it.

The form walks through several categories, and each one asks you to disclose what you actually know, not what a home inspector might eventually find:

Structural components: roof, foundation, walls, and any known defects or past repairs
Systems and appliances: plumbing, electrical, HVAC, and whether anything included in the sale doesn't work properly
Permits and additions: any room additions, garage conversions, or remodels, and whether they were permitted
Environmental hazards: known issues like asbestos, mold, or soil problems
Neighborhood conditions: nuisances, easements, or shared driveways that could affect the buyer's use of the property

Sellers often miss the small stuff. A leaky faucet you've lived with for years, a room addition your uncle built without pulling a permit back in the 1990s, or a persistent drainage issue in the backyard after heavy rain. These feel minor to you because you've adapted to them. To a buyer, they're material facts, and leaving them off the TDS is exactly the kind of omission that surfaces in a demand letter eighteen months after closing.

If you've had a professional inspection or a specialist's report (a roofer's assessment, a pest control report, a plumber's write-up), attach it to your disclosure packet. It doesn't just inform the buyer. It shows you disclosed everything you had in hand, which matters if a dispute ever comes up.

Pro Tip: Keep a running list of every repair, quote, and inspection report from the day you move in, not the week you decide to sell. Reconstructing a home's history from memory five or ten years later is where honest sellers accidentally leave things out.

Seller Property Questionnaire: Why Does It Matter Alongside the TDS?

The SPQ isn't a substitute for the TDS. It's a deeper dive that many California brokers use to catch details the standard form doesn't ask about directly. If your TDS is the summary, the SPQ is the follow-up interview.

Expect questions like these:

Has any part of the property had unpermitted construction or alterations?
Have you filed an insurance claim for water damage, fire, or other loss?
Has there been any pest control treatment, mold remediation, or foundation repair?
Are you aware of any soil, drainage, or grading issues on the lot?

Answer these the same way you approach the TDS: honestly, and with paper to back it up. If you filed an insurance claim for a roof leak in 2022 and had it repaired, say so, and attach the repair invoice. That single document does more to protect you than a vague verbal assurance to your agent that "it's fine now."

Some brokerages use the SPQ as their default practice on every listing, following C.A.R.'s disclosure chart guidance, while others rely on substituted disclosure forms tailored to a specific transaction type. Ask your agent which approach they're using and why, especially if you're selling a property with a complicated history like a prior remodel or a past claim.

Natural Hazard Disclosure: What Hazards Get Reported and How?

The NHD Statement tells buyers whether your property sits in a mapped hazard zone, and Civil Code Article 1.7 spells out exactly which hazards require reporting. This isn't a form you fill out from memory. It's produced by a third-party disclosure company that pulls data from state and federal hazard maps.

The hazards typically covered include:

Special flood hazard areas (as mapped by FEMA)
Area of potential flooding from dam failure
Very high fire hazard severity zones
Wildland fire zones outside those severity zones
Earthquake fault zones
Seismic hazard zones, including liquefaction and landslide risk

One statistic worth remembering: California's fire hazard severity zone maps get periodically updated by state and local fire authorities, so a property that wasn't in a high-severity zone five years ago might be now. Check current status through Cal Fire's Ready for Wildfire resources rather than assuming an older report still holds.

Here's where sellers get tripped up: sometimes a map result is ambiguous, especially near a zone boundary. If your parcel sits close to a mapped fault line or fire severity boundary and the report is unclear, the safer move is to mark "yes" and attach a verification report from a licensed surveyor or geologist rather than guessing "no" and hoping it doesn't come up later. The DRE booklet makes clear that relying on an official public agency map, obtained with ordinary care, can limit your exposure on that specific item, but only if you actually delivered accurate, current information.

What Does AB 455 Require California Sellers to Disclose in 2026?

Starting January 1, 2026, AB 455 requires California sellers to disclose any known history of smoking or vaping on the property. This is a genuinely new obligation, and it catches a lot of sellers off guard because it isn't about odor you can smell during a walkthrough. It's about what you know.

A few things to keep in mind as you think through this disclosure:

Repainting walls or replacing carpet doesn't erase the disclosure duty if you know a prior occupant smoked or vaped regularly inside
The obligation applies to your own tenancy and to any history you're aware of from previous owners or tenants
Vague language like "not aware of any issues" won't hold up if you actually knew otherwise

Pro Tip: If a previous tenant smoked indoors and you handled remediation (ozone treatment, sealant, new drywall), document what you did and disclose the history anyway. A buyer who later claims you concealed a known issue has a much weaker case against a seller who put it in writing upfront.

Which Specialized Disclosures Might Apply to Your Property?

Beyond the core forms, plenty of California sellers run into notices tied to their specific city, property type, or history. These don't apply to everyone, but when they do, they're not optional.

Mello-Roos or CFD notices: if your property carries a special tax assessment for infrastructure, buyers need to see the annual amount and the duration
Private Sewer Lateral (PSL) disclosure: some California cities require sellers to certify sewer lateral condition or complete repairs before closing, so checking local ordinance requirements early avoids a last-minute scramble
Federal lead-based paint pamphlet: mandatory for any home built before 1978, paired with a specific disclosure form
Meth lab cleanup notices: required if the property was ever subject to a contamination cleanup order
Industrial use zone notices: applicable if the property sits near designated industrial or agricultural zones
HOA and CC&R disclosures: if you're in a homeowners association, buyers need governing documents, dues, and any pending assessments

Are Any California Home Sellers Exempt From These Disclosure Rules?

Not every seller has to complete the full TDS and NHD package. Civil Code Section 1102.2 lists specific statutory exemptions, and if you fall into one of these categories, the standard forms may not apply to your transaction.

Court-ordered sales, including probate transfers
Foreclosure sales and trustee's sales
Transfers between co-owners or within a family (certain qualifying transfers)
Bankruptcy-related transfers
New construction sales covered by a public report

Even if you're legally exempt, voluntary disclosure of known material facts is still worth considering. Exemption from the statutory form doesn't eliminate the general duty to avoid fraud or intentional concealment. If you're handling an inherited property or a trust transfer, talk with an attorney before assuming you're fully in the clear. Estate and trust situations often have nuances that a generic exemption doesn't fully cover.

When Must Disclosures Be Delivered, and What Happens if They're Late?

Timing isn't just a formality here. It creates real legal windows that can unravel a deal if missed.

California law requires disclosures to be delivered "as soon as practicable" before the transfer of title, and most brokerages aim to get the full packet to buyers before or within about seven days of an accepted offer
If disclosures arrive after the buyer has already signed the purchase agreement, the buyer may have a limited period to cancel, depending on delivery method and timing as prescribed by law.
Electronic delivery has its own timing rules, so confirm with your agent whether your delivery method starts the clock correctly

Document everything. A dated email, a signed receipt, or a delivery confirmation from your escrow officer protects you if a buyer later claims they never got the disclosures on time. Late delivery doesn't just risk a cancellation. It can also reopen negotiations right when you thought the deal was locked.

Who's Responsible: You or Your Real Estate Agent?

Your agent has a separate duty from yours, and it's worth understanding where the line falls. Real estate agents must conduct a reasonably competent and diligent visual inspection of the property under the DRE's guidance, and document their findings on the Agent Visual Inspection Disclosure.

Your duty covers what you actually know about the property's history and condition
Your agent's duty covers what a reasonable visual inspection would reveal, not hidden defects behind walls or under flooring
If multiple brokers are involved in a transaction, each one may carry a separate delivery and inspection responsibility
Agent-level knowledge and seller-level knowledge create two distinct disclosure obligations, so one party's honesty doesn't excuse the other's negligence

What Happens if You Fail to Disclose a Known Issue?

Buyers who discover an undisclosed defect after closing generally have real options, and the deadline to act isn't always short. Under the discovery rule, a claim can surface years after the sale, tied to when the buyer actually found the problem rather than when the sale closed.

A buyer who proves a seller knew about a defect and failed to disclose it may pursue actual damages under Section 1102.13, and in cases involving intentional concealment, a fraud claim can carry additional exposure well beyond simple repair costs.

Keep every receipt, every written repair description, and every inspection or specialist report you've gathered. If you're unsure whether something needs to go on the form, attaching a Home Inspection Report or an expert's written opinion is almost always safer than leaving the space blank.

How Should You Prepare Your Disclosure Package Before Listing?

Getting this right isn't about filling out forms the night before your listing goes live. It's about building a paper trail months in advance.

Gather your documents first: permits, repair receipts, insurance claim records, and any HOA paperwork tied to the property
Order the NHD report early, and if any hazard zone result looks ambiguous, get a verification report from a licensed professional before you finalize the form
Complete the TDS and SPQ with full honesty, including the AB 455 thirdhand-smoke disclosure if it applies to your property's history
Time-stamp delivery of every disclosure document, and keep digital and physical copies well past closing in case a question surfaces later
If you're selling fast or as-is, know that a cash offer can simplify logistics, but it doesn't remove your statutory disclosure duties

Pro Tip: Build your disclosure packet the same week you decide to sell, not the week you list. Sellers who assemble their paperwork early tend to move through escrow with fewer renegotiations, because there's nothing left for a buyer's inspector to "discover" that you hadn't already put in writing.

Why Full Disclosure Actually Speeds Up Your Sale

Sellers who disclose everything upfront, even the unflattering stuff, tend to close faster and face fewer renegotiations. Buyers relax when they see documentation instead of vague reassurances. A thorough, honest disclosure packet becomes your best defense if a dispute ever surfaces after closing. Some sellers still choose a cash sale specifically to sidestep repair negotiations, but even then, the disclosure duty travels with the property, not around it.

Full disclosure compliance takes time you might not have if you're facing foreclosure, an inherited property, or a home that needs more repairs than your budget allows. Some cash buyers purchase homes in any condition throughout San Luis Obispo County, often closing in a matter of days instead of the weeks a traditional listing demands.
