California Wildfire Insurance Claims in 2025: Smoke Damage, Mudslides, and Your Right to “All Loss by Fire”

By: Alexander Cohen and Kevin Pollack

Updated: September 2025 (reflecting this year’s fires and cases)

TLDR

• Yes, smoke/soot/ash contamination can be covered—even when a home is still standing—under California’s “all loss by fire” standard (Insurance Code §§ 2070–2071).
• Mudslides after wildfires may be covered under the efficient proximate cause doctrine, as reaffirmed by DOI Bulletin 2025-3.
• Lab testing matters. Courts increasingly recognize contamination at the microscopic level as damage requiring remediation.
• If your insurer refuses to consider lab results or says “smoke is just dust,” you have strong legal grounds to push back.

Why This Matters Now

On January 7, 2025, wildfires devastated Pacific Palisades, Malibu, Altadena, and Pasadena, destroying over 20,000 structures and burning more than 50,000 acres. Families who lost their homes faced displacement. Others, whose homes remained standing, discovered another crisis: toxic smoke and soot contamination.

Homeowners told us:

“I almost wish the house had burned—it might be easier than battling contamination.”

This isn’t exaggeration. Contaminants like asbestos, heavy metals, lead, formaldehyde, cyanide, and carcinogens infiltrate walls, insulation, and HVAC systems. Without professional remediation, these homes are unsafe—and yet insurers often resist paying.

The Legal Foundation: California’s “All Loss by Fire” Rule

In 1909, after the 1906 San Francisco earthquake and fires, California mandated a Standard Fire Policy. Today, it’s codified in Insurance Code §§ 2070–2071.

The promise is clear: insurers must cover “all loss by fire.”

• Any policy that narrows coverage below this standard is invalid.
• “All loss” includes contamination that renders property uninhabitable.
• This standard is broader than modern “direct physical loss” wording found in most “all-risk” policies.
• While insurers can use different coverage triggering language  in all-risk policies, for the peril of fire the coverage must be “substantially equivalent” to the coverage offered under Insurance Code § 2071 or it is unenforceable.

What Counts as “Physical Damage”?

Courts have clarified that damage does not need to be visible to trigger coverage. It can occur at the microscopic level.

Another Planet Entertainment, LLC v. Vigilant Ins. Co. (2024) 15 Cal. 5th 1106

The California Supreme Court held that “direct physical loss or damage” may include:

• Distinct physical alteration (even if microscopic and invisible)
• Functional impairment (property unusable or uninhabitable)
• Saturation or ingraining of contaminants requiring remediation

The court distinguished losses requiring active remediation (triggering coverage) from Covid-19’s evanescent presence (no coverage) which is easily cleanable because it dissipates.

2025 Wildfire Cases That Changed the Landscape

 Bottega LLC v. National Surety Company (N.D. Cal. 2025) 2025 WL 71989

A California restaurant closed after wildfire smoke made it unsafe to operate.

• Furniture and fixtures were affected and the smell lingered for a long time.
• Insurer’s argument: Smoke is like COVID, easily cleaned and causes no physical damage.
• Court’s finding: Smoke is more like asbestos—it physically alters property.
• Takeaway: Functional impairment = covered loss.

Gharibian v. Wawanesa General Ins. Co. (2025) 108 Cal.App.5th 730

Homeowner alleged smoke damage but provided no objective proof of damage – no physical alteration, no functional impairment, and no ingraining, saturation, or absorption of contaminants.

• Court’s finding: No coverage, due to lack of evidence—not because smoke isn’t covered.
  • But the Court didn’t address or consider Insurance Code § 2071’s “all loss by fire” standard.
• Why it matters: Insurers misuse Gharibian to argue smoke isn’t compensable, but the ruling is limited to cases with no admissible evidence.
• The California Department of Insurance’s Response – March 7, 2025 Bulletin  -highlighting the case is limited to its facts and “should not be interpreted as supporting denial of coverage for smoke damage in all instances as a matter of law.”

Nolte v. Allstate Ins. Co. (Super. Ct. L.A. County, July 7 2025, No. 20STCV41595) and

Hamilton v. Allstate Ins. Co. (Super. Ct. L.A. County, July 29 2025, No. 20STCV38853)

• Insurer’s defense: Relied on Gharibian, claiming smoke damage wasn’t covered because it was not visible or permanent.
• Homeowners’ response:
  • Argued Insurance Code § 2071 “All Loss by Fire”
  • Presented CIH testing showing fire contamination embedded in walls and contents, but the insurer ignored it.
  • Argued that when insurers fail to conduct thorough, objective, and fair investigations to evaluate the full extent of damage, they fail to honor their obligation to fully restore their insurance customers’ property to “pre-loss” condition and leave the homeowners exposed to health and safety risks.
• Outcome: Courts let claims proceed to trial for bad faith and punitive damages, neutralizing Gharibian misuse.

Aliff v. California FAIR Plan Assn., Super. Ct. L.A. County, June 24, 2025, No. 21STCV20095

• FAIR Plan’s policy requires smoke damage to cause:
  • Permanent physical changes;
  • That it be visible to the naked eye or
  •  smellable to the nose, and
  •  Excludes the use of lab testing.
• Court’s ruling: Unlawful under Insurance Code § 2071. Microscopic contamination is sufficient.
• Impact: DOI launched an enforcement action in 2025 against FAIR Plan for illegal policy language.

Mudslides After Fires: The Efficient Proximate Cause Rule

Burned hillsides plus heavy rain = mudslides. Standard policies exclude “earth movement.”

But under the efficient proximate cause doctrine (DOI Bulletin 2025-3):

• If fire is the dominant cause and mudslide is the ensuing loss, the fire peril controls.
• Result: Coverage applies despite exclusions.

Step-by-Step: Protecting Your Wildfire Claim

1. Get Your Policy and Endorsements
   • Ask for the full policy, not just the declarations page.
2. Document Everything
   • Photos, videos, receipts for housing and remediation. Keep a timeline.
3. Insist on Professional Testing
   • Hire Certified Industrial Hygienists (CIHs) to test for contaminants. Core and HVAC sampling matter.
4. Retain the Right Experts
   • CIHs
   • Licensed general contractors
   • Structural engineers
   • HVAC specialists
   • Remediation contractors
   • Contents specialists
   • Real estate appraisers
   • Pool & landscape experts
5. Know Your Codes
   • Insurance Code §§ 2070–2071 and regulations on declared emergencies (ALE, rebuild flexibility, etc.).
6. Push Back on Denials
   • If your insurer ignores lab data or relies on visual inspections alone, cite the 2025 cases and DOI bulletins.

FAQ

Is smoke damage covered if my house didn’t burn?
Yes. Under California’s “all loss by fire” rule, smoke/soot/ash contamination that impairs habitability or requires remediation is covered.

My insurer says it’s just dust—what now?
Request CIH testing. Contaminants like asbestos, cyanide, and heavy metals are invisible but dangerous.

Are mudslides after a wildfire covered?
Yes, if fire is the dominant cause. See DOI Bulletin 2025-3.

Can my insurer refuse lab testing?
No. Courts (e.g., Aliff) found policies excluding lab results unlawful.

What if my insurer cites Gharibian to deny?
Remind them Gharibian was about lack of evidence. Present lab results and other forms of objective evidence to prove damage.
