California is one of the most rewarding states to sell property in — and one of the most complicated. Home values are high, demand from qualified buyers is strong, and the state has spent decades building one of the most comprehensive seller disclosure frameworks in the country.
If you're selling in California in 2026, there's a long checklist of legal requirements, tax implications, and market conditions you need to understand before you list. This guide covers everything from mandatory disclosures to transfer taxes to the ongoing home insurance crisis.
What Disclosures Are Required When Selling a Home in California?
California requires more seller disclosures than almost any other state. These aren't optional — failure to disclose can expose sellers to lawsuits long after closing. Here's what's required for most residential transactions.
What Is the Transfer Disclosure Statement (TDS)?
The Transfer Disclosure Statement is California's foundational disclosure form, required for virtually all residential sales of 1–4 units. It asks sellers to disclose known material defects affecting the property — roof condition, plumbing, electrical, past flooding, pest infestations, neighborhood nuisances, and dozens of other issues.
Sellers must complete the TDS honestly and thoroughly. "I didn't know" is not a defense if a court finds you reasonably should have known about a defect.
What Is the Natural Hazard Disclosure (NHD)?
California requires sellers to disclose whether the property lies within designated natural hazard zones. A licensed Natural Hazard Disclosure provider (typically ordered through escrow for $100–$150) generates a report covering:
- Earthquake fault zones (Alquist-Priolo Act fault zones)
- Seismic hazard zones (liquefaction and landslide risk)
- State Fire Responsibility Areas (SFRA) and Very High Fire Hazard Severity Zones (VHFHSZ)
- Flood zones (FEMA Special Flood Hazard Areas)
- Dam failure inundation zones
- Wildland-urban interface areas
In 2026, fire hazard zone disclosures are particularly significant given ongoing insurance market disruptions (more on that below).
What Is the Seller Property Questionnaire (SPQ)?
The Seller Property Questionnaire supplements the TDS with more detailed questions about the property's history — unpermitted additions, HOA disputes, litigation, easements, boundary issues, and neighborhood conditions. Together, the TDS and SPQ form the core of California's seller disclosure package.
What Other Disclosures Are Required?
Beyond the TDS, NHD, and SPQ, California sellers may need to provide:
- Lead-based paint disclosure — Required federally for homes built before 1978. Buyers get a 10-day inspection period specifically for lead.
- Mello-Roos disclosure — If the property is in a Community Facilities District (CFD), sellers must disclose the special tax obligation, which can be $1,000–$5,000+ per year on top of regular property taxes.
- Supplemental property tax notice — Buyers need to understand that a sale triggers a reassessment, which can dramatically increase their annual tax bill.
- HOA disclosures — Extensive documentation package if the property is in a homeowners association, including CC&Rs, financials, meeting minutes, and pending assessments.
- Water heater and smoke detector compliance — Sellers must certify that water heaters are properly braced and that smoke and carbon monoxide detectors are installed and functioning.
- Window security bars — If present, disclosure and buyer acknowledgment are required.
How Do California Transfer Taxes Work?
California imposes transfer taxes when real property changes hands. These are typically paid by the seller and calculated based on the sale price.
What Is the County Transfer Tax?
The base California county transfer tax is $1.10 per $1,000 of sale price (or $0.55 per $500). On a $900,000 sale, that's $990.
Do Cities Charge Additional Transfer Taxes?
Many California cities layer their own transfer taxes on top of the county rate. Some of the most significant:
| City | Transfer Tax Rate | Cost on $1M Sale |
|---|---|---|
| Los Angeles (city) | $4.50 per $1,000 + county | ~$5,490 |
| San Francisco | Progressive (see below) | Varies dramatically |
| Culver City | $4.50 per $1,000 + county | ~$5,490 |
| Pomona | $2.20 per $1,000 + county | ~$3,300 |
| Santa Monica | $3.00 per $1,000 + county | ~$4,100 |
San Francisco's transfer tax is particularly notable: it's progressive and can be substantial on high-value properties. Properties selling for $5–$10 million face a 2.75% rate; properties over $25 million face 6%. A $7 million SF property would owe approximately $192,500 in transfer taxes.
Los Angeles's Measure ULA (the "mansion tax") added a 4% transfer tax on properties at $5–$10 million and 5.5% above $10 million. Sellers of high-value LA properties should confirm its current status with their agent or attorney.
What Are the Capital Gains Tax Implications for California Sellers?
California taxes capital gains as ordinary income — there's no preferential rate. This is a significant difference from federal tax treatment and one of the most important financial considerations for California sellers.
Federal vs. California Capital Gains Tax
- Federal: Long-term capital gains (property held 12+ months) are taxed at 0%, 15%, or 20% depending on income
- California: All capital gains taxed as ordinary income at rates up to 13.3%
Combined federal and California capital gains tax can reach 33%+ for high-income sellers.
The Primary Residence Exclusion
Most homeowners can exclude $250,000 in capital gains (single filer) or $500,000 (married filing jointly) from both federal and California tax — provided you've lived in the home as your primary residence for at least 2 of the last 5 years. This exclusion eliminates tax exposure for most sellers in moderate-priced markets.
For sellers in expensive California markets who've owned for many years, gains above the exclusion can be substantial. A couple who bought in the Bay Area for $600,000 in 2010 and sells for $1.5 million in 2026 could have $400,000 in taxable gains — roughly $52,000–$80,000 in combined federal/state tax depending on their income.
What Happens to Property Taxes (Prop 13) When You Sell?
Your Prop 13 tax basis does not transfer to the buyer. When a California property changes hands, it triggers a reassessment to current market value.
This is critical context for buyers (their tax bill will be much higher than yours was), and it's something sellers must disclose through the supplemental tax notice. A buyer purchasing your $1.2 million home may see annual property taxes jump from your $3,000/year (if you've owned since the 1990s) to $15,000/year at current assessed value.
California offers limited exceptions that allow Prop 13 basis transfers — for parents transferring to children (Prop 19, which tightened in 2021) and for seniors 55+ purchasing a replacement home. Consult a tax professional if these apply.
What's Happening With California Home Insurance in 2026?
The California homeowner insurance market remains severely stressed in 2026, particularly in fire-prone areas. Several major insurers have stopped writing new policies or withdrawn from the state, and many California sellers are navigating this reality as part of their transaction.
Key points for sellers:
- Buyers scrutinize insurance availability — a home in a High Fire Hazard Severity Zone that can't be insured affordably can kill a deal
- The FAIR Plan — California's insurer of last resort — has seen enrollment surge; buyers face premiums 3–5x standard market rates
- Disclose known insurance issues proactively — surprises in escrow cause deals to collapse
- Insurance contingencies are increasingly common — buyers want an out if they can't obtain coverage
If your property is in a fire zone, confirm what coverage is available before you list.
What Does the Timeline of a California Home Sale Look Like?
A typical California residential transaction from listing to close takes 30–45 days, though this can vary based on financing type and complexity.
| Phase | Typical Timeline |
|---|---|
| Prepare disclosures, staging, photography | 1–2 weeks before list |
| Active on MLS | Days 1–14 (offer review period) |
| Offer acceptance and ratification | Day 7–14 |
| Inspection period | Days 1–17 after acceptance |
| Buyer loan contingency period | 21 days (default) |
| Appraisal contingency | Within loan period |
| Contingency removal | Day 21–25 |
| Final walkthrough | 5 days before close |
| Close of escrow (COE) | Day 30–45 |
California escrow is handled by neutral third-party escrow companies (unlike many other states that use attorneys). Escrow coordinates the exchange of funds, the recording of the deed, and the distribution of proceeds.

FAQ
Are seller disclosures required in California even if the buyer is purchasing "as-is"?
Yes. "As-is" in California means the buyer agrees to purchase without requesting repairs — it does not relieve the seller of disclosure obligations. You must still complete the TDS, SPQ, NHD, and all other required disclosures. Concealing known defects in an as-is sale can still result in legal liability.
How is capital gains tax calculated when selling a California home?
Start with your sale price, subtract your adjusted cost basis (original purchase price plus capital improvements), and that's your gain. Subtract the primary residence exclusion ($250,000 single / $500,000 married) if you qualify. The remaining taxable gain is subject to federal capital gains rates (0–20%) and California income tax rates (up to 13.3%). Consult a CPA for your specific situation.
What is a Mello-Roos tax and does it affect my home sale?
Mello-Roos is a special tax levied in Community Facilities Districts (CFDs), common in newer California subdivisions. It funds infrastructure and community services and can run $1,000–$5,000+ per year. Sellers must disclose if the property is subject to Mello-Roos. The buyer takes on this obligation at closing — it can affect their purchasing power and must be factored into offer negotiations.
What happens to escrow in a California home sale?
Escrow is handled by a neutral, licensed escrow company (not an attorney). Once both parties sign the purchase agreement, escrow opens and coordinates all transaction milestones: receiving the buyer's deposit, ordering title, facilitating contingency removals, coordinating with the lender, and ultimately disbursing funds and recording the deed on closing day.
Do I need a real estate attorney to sell a home in California?
California does not require an attorney for residential real estate transactions — a licensed real estate broker and escrow officer handle the process. However, for complex situations (estate sales, title disputes, divorce, commercial-residential mixed use), consulting a real estate attorney is advisable.
