Wildfire smoke damage to a house that did not burn: what California requires of the claim
A house that survives a wildfire can still have a smoke claim. California's Department of Insurance said in Bulletin 2025-7, dated March 7, 2025, that smoke damage can be covered where a policy insures against direct physical loss of or damage to property, that insurers may not deny such claims without an appropriate investigation, and that when professional testing is warranted the insurer should arrange and pay for it. Below, that bulletin, the standard policy's smoke wording and California's disaster claim rules become a checklist and an evidence log for a standing home.

Why smoke claims are disputed
Fire damage is easy to see. Smoke damage often is not. Soot and ash settle into ductwork, insulation, carpets and soft furnishings; odor lingers; residue can sit on surfaces that look clean. That gap between what is visible and what is there is where smoke claims get argued, and it is why the legal standard matters more here than for most losses.
Homeowners policies generally pay for direct physical loss or damage. The California Supreme Court explained what that means in a 2024 decision, Another Planet Entertainment, LLC v. Vigilant Insurance Company, as quoted in the department's bulletin: under California law, direct physical loss or damage to property requires a distinct, demonstrable, physical alteration to property. The physical alteration need not be visible to the naked eye, nor must it be structural, but it must result in some injury to or impairment of the property as property. Read that sentence twice. It cuts both ways: a smoke claim does not need visible damage, but it does need evidence that the property was physically altered and impaired, not just that smoke passed by.
A 2025 California Court of Appeal decision involving Wawanesa General Insurance Company held that the homeowners' smoke evidence in that case was not enough to establish coverage. Some insurers read it broadly. The department rejected that reading in Bulletin 2025-7: the decision is limited to the facts of that case, does not conflict with the Supreme Court's ruling, and should not be interpreted as supporting denial of smoke damage coverage in all instances as a matter of law. The practical lesson from both cases is the same. Smoke claims are decided on evidence, so the claim file has to carry it.
What Bulletin 2025-7 asks of insurers, point by point
The bulletin is addressed to all property and casualty insurers handling smoke damage claims for properties in California wildfire areas, and it says its expectations apply to every insurer, including the California FAIR Plan. A bulletin states the department's position and expectations; the statutes and regulations it cites are the binding rules. Here is what it says, set beside what each point means for a homeowner.
| The bulletin says | Source it relies on | What to do with it |
|---|---|---|
| Recent cases do not support the position that smoke damage is never covered as a matter of law | Another Planet (Cal. Supreme Court, 2024) | If a denial says smoke is never covered, ask the insurer to cite the policy language and the facts it relied on |
| Whether a claim is covered depends on the specific policy language and the unique facts of each claim | The bulletin's own position | Read your policy's insuring agreement and smoke wording; build the facts with testing and photographs |
| Insurers must adopt and implement reasonable standards for processing smoke claims and make good faith efforts at prompt, fair and equitable settlements where liability is reasonably clear | Insurance Code section 790.03(h) | Ask the insurer for its standards for evaluating smoke claims, in writing |
| Every insurer must conduct and diligently pursue a thorough, fair and objective investigation | Fair Claims Settlement Practices Regulations, 10 CCR 2695.7(d) | Request an inspection; note in writing if none was offered |
| It is not reasonable to deny a smoke claim without an appropriate investigation | The bulletin's guidance | A denial with no inspection or testing is a point to raise with the department |
| It is not reasonable to require the insured to incur substantial costs to investigate their own claim | The bulletin's guidance | Before paying for testing yourself, ask the insurer to arrange it |
| If professional testing is warranted, the department expects the insurer to contract and pay for it | The bulletin's guidance | Put the testing request in writing and ask who will pay |
| Insurers are encouraged to consider distributing low-cost at-home test kits as a first step where professional testing may not be initially warranted; results may warrant more investigation | The bulletin's guidance | Use a kit if offered, keep the results, and ask for professional testing if they show contaminants |
| Insurers should handle smoke claims in compliance with laws, regulations and best practices for remediation | The bulletin's guidance | Ask what remediation standard the insurer's scope follows |
The bulletin also records a health reason for care. Citing the Los Angeles County Department of Public Health, it says fire debris and ash from wildfires may contain asbestos, heavy metals, chemicals and other hazardous substances, and that improper handling can spread them through a community. That is the reason testing and proper remediation, not a quick wipe-down, sit at the center of the department's expectations.
What the policy itself says about smoke
Every quotation in this table is taken from the sample homeowners form the Insurance Information Institute posts online: ISO's Homeowners 3 Special Form, the October 2000 edition (HO 00 03 10 00). California law adds rules of its own, and insurer forms differ from the sample, so read your own policy's insuring agreement and smoke language alongside this.
| Part of the policy | How the HO-3 sample treats smoke | What it means for a smoke claim |
|---|---|---|
| Coverage A, the dwelling, and Coverage B, other structures | Insured against direct physical loss unless the loss is excluded. Exclusion A.2.c.(6)(d) removes smoke from agricultural smudging or industrial operations, and (6)(e) removes the discharge, dispersal, release or escape of pollutants, which the form defines to include smoke, vapor, soot and fumes, unless the discharge is itself caused by a Peril Insured Against named under Coverage C | Fire or lightning and smoke are both Coverage C named perils, so smoke and soot released by a wildfire usually fall within the exception to the pollutants exclusion in the sample. Once that is settled, the question becomes whether the home suffered direct physical loss. Insurer forms differ, so check your own exclusion wording |
| Coverage C, personal property | Insured for named perils; peril 7, Smoke, means sudden and accidental damage from smoke, and does not include smoke from agricultural smudging or industrial operations | Smoke damage to belongings is a named peril in the sample; document each damaged item |
| Coverage D, loss of use | Pays additional living expense if a covered loss makes the residence premises not fit to live in, and up to two weeks if a civil authority prohibits use because of direct damage to a neighboring premises by a covered peril | An uninhabitable smoke-damaged home can trigger living expense coverage; California adds its own rules, below |
| Duties after loss | Prompt notice, protect the property from further damage, keep records of repair expenses, prepare an inventory, show the damaged property, and send a signed sworn proof of loss within 60 days after the insurer's request | Do not discard damaged items before they are documented; California extends the proof-of-loss timing after a declared emergency |
The table leaves two working conclusions. First, because the dwelling coverage in the sample is written against direct physical loss, the Supreme Court's definition of physical alteration is the standard your evidence has to meet for the structure. Second, smoke is a named peril for contents in the sample, which makes an item-by-item inventory the heart of the personal property part of the claim. Our home inventory guide shows the format.
California's disaster claim rules that apply to a smoke claim
When the fire is part of a declared state of emergency, California law adds time and protections that change how a smoke claim should be paced. The department's 2026 annual notice of significant laws, dated January 9, 2026, summarizes them. These apply to losses relating to a state of emergency as defined in Government Code section 8558; the notice warns that the version to use depends on the date of the emergency.
| Rule | What it provides | Code section cited by the department |
|---|---|---|
| Proof of loss | The insurer shall not require proof of loss less than 100 days after the loss, and must grant additional three-month extensions for good cause when delays are beyond the insured's control | Insurance Code 2051.5(b)(3) |
| Time to collect full replacement cost | No less than 36 months from the first actual cash value payment, with six-month extensions for good cause (12 months outside a state of emergency) | Insurance Code 2051.5(b)(1) and (2) |
| Additional living expenses when uninhabitable | If a covered peril renders the home uninhabitable, a policy with living expense coverage shall not limit recovery, though the insurer may instead provide a reasonable alternative remedy that addresses the condition preventing habitation | Insurance Code 2060(b)(2) |
| Duration of living expenses in an emergency | At least 24 months from the inception of the loss, with up to 12 more months for delays beyond the insured's control, and six-month extensions for good cause | Insurance Code 2060(b)(1) |
| Civil authority orders | Where an order restricts access to the home in connection with a covered peril, living expense coverage for at least two weeks, with two-week extensions for good cause | Insurance Code 2060(c) |
| List of covered living expenses | On request, the insurer must provide a list of items it believes would be covered | Insurance Code 2060(a) |
| Copy of the policy | After a covered loss, a complete current copy of the policy, endorsements and declarations page, free, within 30 calendar days of a request | Insurance Code 2084 |
| Appraisal | After a government-declared disaster, appraisal may be requested by either side but shall not be compelled | Insurance Code 2071 |
Two of these deserve action on the first day. Ask for the complete policy copy under section 2084, because a smoke claim turns on the insuring agreement and the smoke wording, and you need the exact words. And ask for the list of covered living expenses under section 2060(a) before you book a hotel. Our additional living expenses guide explains the additional-cost test that decides what is reimbursed.
In September 2026 the Legislature passed and the Governor signed further smoke damage bills, including AB 1642 and AB 1795, according to CalMatters reporting of September 15, 2026. The desk could not read the chaptered text on the official legislative site during this check, so this page does not describe their terms; check the Department of Insurance for how they apply to your claim and when.
Building the evidence: the smoke claim log
The Supreme Court's standard asks for demonstrable physical alteration. The bulletin asks insurers to investigate thoroughly. The evidence log below is how a homeowner meets both halves. It is this desk's practical worksheet, not a form any regulator requires. Keep one row per area of the home and one row per tested surface, and send copies with your claim.
| Area or item | What to record | Evidence that tends to carry weight |
|---|---|---|
| Exterior surfaces, roof, gutters | Ash or char deposits, staining, the date first noticed | Dated photographs, close-ups with a scale, before any cleaning |
| HVAC system and ductwork | Whether the system ran during the fire, filter condition, odor at the vents | Photographs of the filter and vent registers; an HVAC inspection report |
| Interior walls, ceilings, attic, insulation | Discoloration, residue on wipe tests, odor by room | Photographs, wipe samples, at-home test kit results, professional sampling results |
| Soft furnishings, carpets, clothing, bedding | Odor, residue, items affected per room | Item inventory with photographs; cleaning or replacement quotes |
| Hard contents and electronics | Residue, corrosion, function | Photographs; repair or cleaning estimates |
| Testing | Who requested it, who performed it, what was sampled, results | Lab reports; the insurer's written response to your testing request |
| Health and habitability | Symptoms or advice that the home was not fit to live in, any civil authority order | Written advice, the order, and dates you were out of the home |
| Communications | Every call and letter with the insurer, adjuster and remediation contractor | Dated notes, names, and copies of letters |
The testing row is the one the bulletin speaks to most directly. Ask the insurer in writing to arrange and pay for testing if it is warranted, and keep its answer. If the insurer offers an at-home kit as a first step, use it and keep the results; the bulletin notes that depending on those results, additional investigation and processing may be warranted. If you test on your own before asking, you may struggle to recover the cost, and you lose the insurer's participation in choosing what is sampled.
Contents: clean, restore or replace
Belongings are often the largest part of a smoke claim on a standing home, and the hardest to agree on. Some items clean well; some hold odor or residue after cleaning; some are cheaper to replace than to restore. The policy wording and the testing decide which is which, not a rule of thumb.
Three clauses in the HO-3 sample shape the answer. Smoke is a named peril for personal property, so the damage has to be sudden and accidental damage from smoke. Personal property settles at actual cash value unless your policy carries a replacement cost endorsement for contents, which changes the basis. And condition D, Loss to a Pair or Set, lets the insurer either repair or replace part of a pair or set to restore its value, or pay the difference in actual cash value before and after the loss; that matters for matched furniture, sectional sofas, and sets of drapes where only some pieces were cleaned successfully.
| Item group | What to ask before agreeing to cleaning | What to keep |
|---|---|---|
| Clothing, bedding, drapes | What cleaning method and standard will be used, and what happens if odor remains | A list by room, photographs, and the cleaner's inventory and results |
| Upholstered furniture and mattresses | Whether testing showed residue in the material, and whether cleaning or replacement is proposed | Photographs, test results, and the written decision |
| Electronics | Whether residue can affect function, and who will test them | Model numbers, photographs, a repair shop's written assessment |
| Food, medicines, cosmetics | Whether the insurer will pay to replace items exposed to smoke and ash | A list, photographs, and disposal records |
| Matched sets | How the pair or set condition will be applied | Photographs of the whole set before and after cleaning |
If a contents cleaning company takes items away, get its inventory of what it took, signed and dated, before anything leaves the house, and photograph each box. A disagreement about whether an item came back clean is far easier to resolve when both sides hold the same list.
A worked claim: how the ledger adds up
A made-up claim shows how the pieces add up. Every figure is invented for clean numbers; none is an average, a quote, or a typical smoke claim, and real results depend on the policy, the testing and the remediation scope.
A home a short distance from a fire perimeter is standing but has ash in the attic and ducts and smoke odor throughout. Testing arranged by the insurer finds residue in the ducts and attic. The remediation scope and contents estimate come to:
| Line (hypothetical) | Coverage in an HO-3 style policy | Amount |
|---|---|---|
| HVAC cleaning and new filters | Dwelling | $4,500 |
| Attic insulation removal and replacement | Dwelling | $7,500 |
| Interior cleaning, sealing and repainting | Dwelling | $12,000 |
| Contents cleaning: textiles, upholstery, clothing | Personal property | $5,000 |
| Professional testing | Arranged and paid by the insurer, per the bulletin's expectation | Not billed to the household |
| Subtotal of covered repair and cleaning | $29,000 | |
| Less deductible, applied once | -$2,500 | |
| Payable before any depreciation holdback | $26,500 |
Adding it up: $4,500 plus $7,500 is $12,000; plus $12,000 is $24,000; plus $5,000 is $29,000; less a $2,500 deductible is $26,500. Living expenses for the weeks the home was being remediated would run on their own line and limit, as Coverage D does, and are not in the table. If the dwelling settles at replacement cost, the insurer may pay the actual cash value first and release the rest when work is done; in a declared emergency, California gives at least 36 months from the first payment to collect the full replacement cost. Our recoverable depreciation guide explains that second payment.
Smoke claim mistakes, and how to answer a denial
Cleaning before documenting. Remediation removes the evidence of physical alteration. Photograph and, where the insurer agrees, test first; then clean. If health requires urgent cleaning, document thoroughly, keep samples or the filters you remove, and tell the insurer in writing what you did and why.
Paying for lab testing before asking the insurer. The bulletin expects the insurer to arrange and pay for warranted testing. Ask first, in writing.
Treating odor as the whole claim. Odor is a symptom. The claim is stronger when it ties odor to residue found by testing in specific places: the ducts, the attic, the textiles.
Mixing living expenses with repair receipts. They are paid under different coverages, limits and clocks. Keep two folders.
A denial that says smoke is never covered. The department's position is that recent cases do not support that statement. Ask the insurer to identify the policy language and facts behind its decision, and bring the exchange to the department if it does not.
A denial that cites a pollution exclusion. The sample's dwelling exclusions include pollutants, and the definition names smoke and soot, so an adjuster may quote it. The same clause carries its own exception: it does not apply when the discharge is itself caused by a Peril Insured Against named under Coverage C, and fire and smoke are both named there. Answer in writing by quoting that exception, ask which cause the insurer says released the smoke, and ask for its own form's wording if it differs from the sample.
Outside California. The bulletin and the disaster claim rules are California's. The policy wording and the evidence log apply anywhere, but the testing and timing rules do not travel; ask your own state insurance department what it expects of insurers after a wildfire.
Disputes about the amount. If the insurer accepts the claim but disputes the remediation price, the policy's appraisal clause may apply, but after a declared disaster California says appraisal may be requested by either side and not compelled. Our appraisal clause guide sets out the process and a break-even worksheet.
If the claim stalls or is denied
Start with the insurer, in writing. Ask what investigation was done, whether testing was considered and why it was or was not arranged, which policy language the decision rests on, and what further evidence would change it. The bulletin says the department will monitor how insurers handle smoke claims. If you still have questions after contacting the insurer, it directs policyholders to the department's toll-free hotline at 800-927-4357 or its website. Send the department the bulletin's own points that you believe were not met, with your evidence log. Our claim denial appeal guide takes the written appeal step by step, and the claim timing guide tabulates California's deadlines for acknowledging, deciding and paying.

Common questions
Does homeowners insurance cover wildfire smoke damage to a house that did not burn?
It can. The California Department of Insurance says recent court cases do not support the position that smoke damage is never covered, and that the California Supreme Court confirmed smoke damage can be covered where a policy insures against direct physical loss of or damage to property. Whether a particular claim is covered depends on the policy language and the facts, so the claim has to show physical alteration to the property, which the court said need not be visible to the naked eye.
Who pays for smoke and ash testing on a California claim?
The California Department of Insurance says that if professional testing is warranted for a specific claim, it expects the insurance company to contract and pay for those services, and that it is not reasonable for an insurer to require the insured to incur substantial costs to investigate their own claim. It also encourages insurers to consider giving policyholders low-cost at-home test kits as a reasonable first step where professional testing may not be warranted at first.
Can my insurer deny a smoke claim without inspecting the house?
California's department says it is not reasonable to deny a smoke damage claim without conducting an appropriate investigation, and points to the Fair Claims Settlement Practices Regulations, which require every insurer to conduct and diligently pursue a thorough, fair and objective investigation. If your claim was denied without an inspection or testing, ask in writing what investigation was done, then contact the department at 800-927-4357 if the answer does not satisfy you.
How long do I have to file proof of loss after a wildfire in California?
For a loss relating to a declared state of emergency, the department's 2026 annual notice says an insurer shall not require proof of loss less than 100 days after the loss, and must grant additional three-month extensions for good cause when an insured acting in good faith meets delays beyond their control. Your policy may give more time. Calendar the date the insurer gives you, in writing.
Will insurance pay for a hotel while my smoke-damaged house is cleaned?
If the home is rendered uninhabitable by a covered peril, California law as summarized in the department's 2026 annual notice says a policy with additional living expense coverage shall not limit the policyholder's right to recovery, though the insurer may instead provide a reasonable alternative remedy that fixes the condition preventing habitation. For a declared emergency, living expense coverage runs at least 24 months, with extensions. Keep receipts from the first night.
Does the HO-3 policy cover smoke damage to belongings?
In the ISO HO-3 sample, personal property is insured for named perils, and smoke is one of them: sudden and accidental damage from smoke, excluding smoke from agricultural smudging or industrial operations. The dwelling itself is insured against direct physical loss unless excluded. Its exclusions name agricultural and industrial smoke and also the discharge of pollutants, defined to include smoke and soot, but the pollutants exclusion does not apply when a Coverage C peril such as fire or smoke caused the discharge, which is how wildfire smoke usually arrives. Insurer forms can differ, so read your own policy's smoke wording.
My insurer denied my smoke claim under a pollution exclusion. How do I answer?
In the ISO HO-3 sample, the pollutants exclusion for the dwelling ends with an exception: it does not apply when the discharge is itself caused by a peril named under Coverage C, and fire and smoke are both on that list. Write back quoting the exception, ask the insurer which cause it says released the smoke and soot, and ask for the exact wording it relies on, because insurer forms can differ from the sample. In California, the department takes calls at 800-927-4357 if the reply ignores the exception.
