California property insurance glossary

Last updated: 2026-04-26 · 81 terms

California property insurance has a vocabulary problem. Carriers use industry shorthand in claim letters; statutes use technical language; and the terms a homeowner needs to understand to evaluate a denial often appear nowhere on the carrier's website.

This glossary is the working vocabulary of California first-party property claims — the terms that come up in denial letters, scopes-of-loss, public-adjuster contracts, and bad-faith complaints. Where a term has a California-specific meaning (FAIR Plan, §790.03 claim-handling regulations, the 2025 Aliff ruling on smoke claims, California Insurance Code §2051.5 on disaster-claim valuation), we say so explicitly. Where a term is industry-standard, we define it the way California PAs and California-licensed insurance attorneys actually use it — not the way an out-of-state insurance dictionary might.

Definitions are short on purpose. If you need depth, the relevant FAIR Plan, wildfire, PA-vs-attorney, and carrier-dispute guides go further. If we've gotten a definition wrong or omitted a term you needed, email [email protected]; we update this page based on reader notes.

A

Actual Cash Value (ACV): The depreciated value of damaged property — replacement cost minus depreciation for age, wear, and condition. ACV is what most California carriers pay first; the depreciation holdback is recoverable only after you complete repairs and submit proof under California Insurance Code §2051.5. Carriers sometimes over-depreciate, which is one of the most common claim disputes.
Additional Living Expense (ALE): Coverage for the increased cost of living away from your home while it is being repaired or rebuilt — rent, hotels, restaurant meals above your normal grocery spend, pet boarding, and storage. California requires ALE for at least 24 months on declared-disaster claims (Insurance Code §2051.5) with extensions available. ALE is one of the most undervalued line items in California wildfire claims.
Aliff ruling: A 2025 California Court of Appeal decision (Aliff v. State Farm) holding that smoke-impacted homes can sustain "direct physical loss" within the meaning of a homeowners policy even when there is no visible char or staining. The ruling reshaped how California carriers must evaluate smoke-only claims after the 2025 Los Angeles fires.
Appraisal clause: A binding alternative-dispute mechanism written into most California property policies. When the policyholder and carrier disagree on the amount of loss (not coverage), each side picks an independent appraiser; the two appraisers pick a neutral umpire; any two of the three sign the award. Appraisal resolves valuation disputes faster than litigation but cannot decide whether a loss is covered.
Apparent authority: A doctrine under which an insurance carrier can be bound by statements its agents or adjusters made if the policyholder reasonably believed the agent had authority to make them. Useful when a carrier later denies a claim based on coverage limits the agent verbally promised but never wrote into the policy.

B

Bad faith: A California tort distinct from breach of contract: an insurance carrier acts in bad faith when it unreasonably denies, delays, or undervalues a claim. Successful bad-faith claims unlock damages above the policy limits, including emotional-distress damages and (under Brandt) attorney fees. Recognized in Egan v. Mutual of Omaha and refined across decades of California case law.
Brandt fees: Attorney fees recoverable as damages in a California bad-faith case under Brandt v. Superior Court (1985). When a policyholder must hire an attorney to recover policy benefits the carrier wrongfully withheld, the attorney fees attributable to recovering those benefits are recoverable as tort damages. Brandt fees are a major reason bad-faith litigation can be economically rational even after a contingency fee.
BPP (Business Personal Property): A commercial-policy line item covering inventory, furniture, fixtures, equipment, and other movable property used in the business. BPP claims often hinge on whether the policy values items at ACV or replacement cost, whether off-premises property is covered, and whether code-upgrade costs apply to replacement equipment.
Business interruption: Coverage for lost net income and continuing expenses (rent, payroll, debt service) while a covered loss prevents normal business operations. Triggered by direct physical loss to insured property; typically subject to a waiting period and a maximum period of restoration. The most-disputed line item in California commercial claims after a wildfire or major water loss.

C

California FAIR Plan: The California Fair Access to Insurance Requirements Plan — the state-mandated insurer of last resort for property owners who cannot obtain coverage in the admitted market. It provides basic fire coverage with strict limits and exclusions; smoke-only damage and many ancillary coverages have historically been more restrictive than admitted-market policies. Penetration in wildfire-exposed California zip codes has risen sharply since 2020.
Carrier: The insurance company that issued the policy and is contractually obligated to handle the claim. In California, "admitted carriers" are licensed by the California Department of Insurance and participate in the California Insurance Guarantee Association; "non-admitted" carriers (often surplus-lines insurers) are not, which affects how disputes are handled.
Catastrophic claim: A claim arising from a Governor-declared state of emergency or a federally declared disaster — typically a wildfire, earthquake, or major flood event. California provides additional consumer protections on catastrophic claims, including extended ALE, simplified proof of loss, and the §15007 seven-day public-adjuster solicitation moratorium.
CDI (California Department of Insurance): The California state regulator overseeing the insurance industry. CDI licenses public adjusters, regulates carrier conduct under Title 10 of the California Code of Regulations, publishes Commissioner's Bulletins, conducts market-conduct examinations, and accepts policyholder complaints at its Consumer Hotline.
CEA (California Earthquake Authority): A publicly managed, privately funded earthquake insurance pool. Standard California homeowners policies exclude earthquake damage; CEA policies are the most common way California homeowners obtain coverage. CEA policies have unusual deductibles (often 10–25% of dwelling limit) and unique claim-handling rules.
Civil authority coverage: A business-interruption sublimit triggered when a civil authority (fire department, sheriff, evacuation order) prohibits access to the insured property because of a covered peril nearby. Common in California wildfire claims where evacuation orders kept businesses closed even though the fire never reached the property. Subject to time limits, distance requirements, and direct-physical-loss preconditions.
Claim file: The carrier's internal record of every action taken on a claim — adjuster notes, scopes, photographs, expert reports, internal valuation calculations, communications with the insured. Policyholders are entitled to request the claim file under California Insurance Code §2071. Refusal to provide it is a common bad-faith allegation.
Code upgrade (ordinance and law): Coverage for the increased cost of rebuilding to current building code rather than the code in effect when the property was originally built. California building codes have tightened significantly post-2008 (energy, wildfire-zone hardening, ADA), so code-upgrade coverage is often the difference between a livable rebuild and a half-rebuilt house.
Commercial property policy: A first-party policy covering buildings, business personal property, and (when endorsed) business interruption for a commercial enterprise. Distinct from a homeowners policy in policy form (typically ISO CP), in valuation defaults, and in available endorsements such as ordinance and law, equipment breakdown, and extra expense.
Contents: Personal property inside the dwelling — furniture, clothing, electronics, kitchenware, decor. Typically covered at 50–70% of dwelling limit on a residential policy. After a total loss, the carrier expects an itemized inventory; producing a credible inventory is one of the highest-value tasks a public adjuster performs.
Contingency fee: A fee structure where the professional is paid only if the client recovers — calculated as a percentage of the recovery. California public adjuster contingency fees are typically 10–20% (10% on disaster claims is common); insurance attorneys typically charge 33–40%. Contingency fees on California PA contracts are regulated by the California Department of Insurance.
Covered peril: A risk for which the policy provides coverage. On a "named-peril" policy, only specifically listed perils are covered; on an "open-peril" or "all-risk" policy (the more common modern form for residential), every peril is covered unless specifically excluded. Identifying whether a loss is a covered peril is the first question on every claim.

D

Declarations page: The cover page of the policy listing the insured, the dwelling and contents limits, the deductible, the policy period, the named carrier, and any endorsements. The first document a public adjuster or attorney reads on any claim. Often abbreviated "dec page."
Deductible: The amount the insured pays out of pocket before coverage applies. California wildfire deductibles are typically a fixed dollar amount on admitted-carrier homeowners policies; CEA earthquake deductibles are a percentage of dwelling limit; FAIR Plan deductibles vary. Wind/hail and named-storm deductibles common in other states are rare in California.
Demand letter: A written communication from the policyholder (or counsel) to the carrier formally demanding payment of policy benefits, often a precondition for litigation. In California, a well-drafted demand letter that documents bad-faith conduct can be the document that finally moves a stalled claim — or sets up a §790.03 claim-handling regulation violation if ignored.
Denial letter: A written communication from the carrier stating that coverage does not apply, citing specific policy language. California carriers must provide a written denial when they decline coverage. The denial letter is the single most useful document for evaluating whether to escalate to an attorney; preserve it and request the claim file in the same response.
Depreciation: The reduction in value of property due to age, wear, and condition. California carriers calculate depreciation using internal guidelines that often produce aggressive results; depreciating life-safety items, structural components, or items with no real loss in functional value is one of the most common dispute points and one a public adjuster routinely contests.
Direct physical loss: The threshold trigger for most first-party property coverages: there must be tangible, physical alteration of the insured property. The 2025 Aliff ruling held that smoke residue and embedded combustion products can constitute direct physical loss even without visible char, expanding coverage on California smoke-only claims.

E

Egan v. Mutual of Omaha: The 1979 California Supreme Court case establishing that an insurance carrier owes its insured an implied duty of good faith and fair dealing, breach of which gives rise to tort damages. The doctrinal foundation of California first-party bad-faith law.
Efficient proximate cause: A California rule of policy interpretation: when a covered peril and an excluded peril both contribute to a loss, coverage applies if the covered peril is the predominant cause. Crucial in wildfire claims where smoke (typically covered) and pre-existing structural conditions (often excluded) overlap.
Engagement letter: The written contract between a public adjuster (or attorney) and a client establishing scope, fee, and termination terms. California law requires public adjusters to use a CDI-compliant contract that discloses the contingency fee, the right to cancel within three business days, and other consumer protections. No engagement letter, no engagement.
Examination under oath (EUO): A formal sworn examination of the insured by the carrier's counsel under a policy provision. The carrier may demand an EUO as a condition of coverage; refusal can be grounds for denial. EUOs are most common on suspected-fraud claims, large losses, and contested claims; insureds typically should not appear at an EUO without representation.
Extended replacement cost: A homeowners-policy endorsement that pays a percentage above the dwelling limit (often 25–50%) when actual rebuild cost exceeds the policy's stated limit. Critical in California wildfire rebuilds because post-disaster construction inflation routinely pushes rebuild cost above pre-loss dwelling limits.
Endorsement: A written modification to the base policy form that adds, removes, or changes a coverage. California homeowners policies typically include endorsements for ordinance and law, extended replacement cost, water backup, and (sometimes) earthquake. Read the endorsements; they often contain the coverage that makes a claim payable.

F

FAIR Plan: See California FAIR Plan above. The shorthand most policyholders use.
First-party claim: A claim by the insured against their own insurance company under the policy they purchased. Distinct from a third-party claim, where someone other than the insured is making a claim against the insured's liability coverage. All property-damage claims by California homeowners and commercial owners are first-party claims.
Force-placed insurance: Insurance the mortgage lender purchases on the property when the borrower's policy lapses, typically at a higher cost and narrower coverage. California has tightened force-placed-insurance rules after past abuses; force-placed coverage almost always pays less than a properly maintained homeowners policy on the same loss.
Forensic accounting: The discipline of reconstructing financial records to support a business-interruption or extra-expense claim. On commercial wildfire and water-loss claims, forensic accountants prepare the lost-income calculation that drives the BI payment. Often a defining cost-benefit decision on commercial claims above $250K.

G

Good faith: The implied covenant in every California insurance policy that the carrier will deal fairly with its insured. Breach is a tort under Egan; good-faith conduct is the affirmative obligation that the §790.03 regulations operationalize. The opposite of bad faith — see above.
Gruenberg v. Aetna: A 1973 California Supreme Court case extending tort recovery to first-party insureds for emotional-distress damages flowing from bad-faith claim handling. Together with Egan, it established that the harm from carrier misconduct goes beyond the unpaid policy benefits.

H

Homeowner policy (HO-3): The most common California residential policy form: open-peril coverage on the dwelling, named-peril coverage on contents, and bundled liability and ALE. HO-3 is the baseline against which California condo (HO-6), renter (HO-4), and FAIR Plan policies are typically compared.
Hazard: A condition that increases the chance of loss — vacant property, knob-and-tube wiring, an unfenced pool, a wood-shake roof in a wildfire zone. California carriers use hazard inspections to support non-renewal decisions; hazards listed in the policy may also affect whether a loss is covered.
Hardship deferral: A California-specific protection allowing policyholders displaced by a declared disaster to defer premium payments and certain policy obligations. Triggered by Governor or Insurance Commissioner declarations after major wildfire and earthquake events.

I

IICRC S500 / S520: Industry standards for water damage restoration (S500) and mold remediation (S520) published by the Institute of Inspection, Cleaning and Restoration Certification. California adjusters and contractors reference these standards when scoping water and mold losses; non-compliant work product is the basis for many supplemental claims.
Indemnity: The principle that insurance restores the insured to their pre-loss financial position — no more, no less. California valuation disputes are arguments about what a true indemnity payment requires: replacement cost, ACV, code-upgrade differential, and so on.
Industrial hygienist (CIH): A Certified Industrial Hygienist is an environmental health professional who tests for airborne and surface contaminants — soot, PAHs, asbestos, heavy metals, mold. On California smoke-only claims after the 2025 LA fires, a CIH report is often the documentary evidence that turns a denial into a paid loss.
Insured peril: A peril that is covered under the policy form. On an open-peril policy, all perils are insured perils unless excluded; on a named-peril policy, only the listed perils are insured. See "covered peril" above.
Insurable interest: A legal interest in the property such that the insured would suffer financial loss if the property were damaged. Required for valid coverage. Becomes relevant in claims involving recently sold property, divorce, inheritance, and disputed ownership.

L

Liability coverage: The portion of a homeowners or commercial policy that pays for bodily injury or property damage the insured causes to others. Distinct from first-party property coverage. Important for California homeowners on dog-bite, slip-and-fall, and pool claims, but rarely the focus of property-damage disputes.
Litigation hold: A formal duty to preserve documents, photographs, communications, and physical evidence relevant to a potential or actual lawsuit. Once litigation is reasonably foreseeable, both the policyholder and the carrier must preserve their records. Spoliation — destruction after the duty attaches — can carry serious sanctions.
Loss of rents: A landlord coverage replacing rental income lost while a covered loss makes the property uninhabitable. The income-replacement analog of ALE, but for property held for rental rather than owner-occupied. Usually written as an endorsement to a rental dwelling policy.
Lowball offer: An informal term for a carrier settlement offer materially below a defensible scope-of-loss valuation. California §790.03(h) lists lowballing as an unfair claim-handling practice when the carrier knows the offer is unreasonably low. The threshold most California public adjusters work above; the threshold a bad-faith attorney might pursue.

M

Matching coverage (§10103): California Insurance Code §10103.5 (and underlying regulations) governs whether undamaged adjacent material — siding, roofing, flooring, cabinets — must be replaced to match repaired sections. California courts and regulators have generally held that "comparable material and quality" requires reasonable matching, not industry-best-effort. A frequent dispute on partial-loss claims.
Mediation: A non-binding alternative-dispute process where a neutral mediator helps the policyholder and carrier negotiate a settlement. California courts often require mediation before trial in bad-faith cases; CDI offers a no-cost mediation program for residential claims under certain dollar thresholds.
Mitigation duty: The insured's obligation to take reasonable steps to prevent further damage after a loss — tarping a roof, drying out a flooded basement, securing a damaged structure. The carrier owes the cost of reasonable mitigation; failure to mitigate can reduce or void coverage on the resulting additional damage.
Mold sublimit: A reduced limit (often $5,000–$25,000) that California homeowners policies typically apply to mold remediation, regardless of the dwelling limit. The dispute on mold claims often turns on whether a higher-limit water-loss endorsement displaces the mold sublimit when mold is the consequence of a covered water loss.

N

Named-peril policy: A policy that covers only the perils specifically listed in the policy form. The narrower of the two main forms. California FAIR Plan policies are named-peril; some commercial policies are named-peril; most modern California homeowners policies are open-peril on the dwelling.
Notice of loss: The insured's formal notification to the carrier that a loss has occurred. Most California policies require prompt notice; what counts as prompt varies. Late notice is a defense the carrier may raise, but in California it is generally a defense only when the delay actually prejudiced the carrier's investigation.

O

Open-peril policy: A policy that covers every peril unless specifically excluded. Sometimes called "all-risk." The standard form on the dwelling section of modern California homeowners policies. Disputes on open-peril policies usually turn on whether an exclusion applies, not whether the peril is listed.
Ordinance and law (code upgrade): The endorsement that pays for the increased cost of rebuilding to current code rather than original code. See "code upgrade" above. Frequently underused on California wildfire claims because policyholders don't know to ask for it; the affiliated firm flags it on every total-loss intake.
Overhead and profit (O&P): A percentage line item (typically 10% overhead and 10% profit) that general contractors add to a job involving three or more trades. California carriers sometimes resist paying O&P on claims where they believe the policyholder will self-perform; California case law generally requires O&P when a GC is reasonably needed to coordinate the rebuild.

P

Period of restoration: On a commercial business-interruption claim, the time period during which the carrier owes lost income — typically beginning at the loss and ending when the property is or could be restored with reasonable speed. The period of restoration is a frequent dispute on California commercial wildfire and water-loss claims.
Policy limits: The maximum amount the carrier will pay under each coverage. Listed on the declarations page. California first-party recovery is generally capped at policy limits; bad-faith damages and Brandt fees are recoverable above policy limits in a successful tort action.
Pre-existing damage: Damage that existed before the loss event. California carriers raise pre-existing damage as a partial defense on roof, foundation, and structural claims. The dispute usually requires comparing pre-loss inspection records, prior claims history, and current scope-of-loss; a public adjuster's job is to isolate damage attributable to the current peril.
Proof of loss: A sworn statement by the insured documenting the loss, the cause, the value, and supporting evidence. Most California policies require a proof of loss within a specified period (often 60 days). On declared-disaster claims California has tightened proof-of-loss requirements in the policyholder's favor; signing a proof of loss does not waive future supplements if new damage is discovered.
Public adjuster: A California-licensed insurance professional who represents the policyholder — not the carrier — in a first-party claim. PAs document the loss, prepare scopes and estimates, and negotiate with the carrier on the policyholder's behalf. Licensed and regulated by the California Department of Insurance under Insurance Code §15000 et seq.

R

Replacement cost (RCV): The cost to replace damaged property with new property of like kind and quality at current prices, without deduction for depreciation. Most California homeowners policies pay ACV first and release the depreciation holdback once repairs are complete and proof submitted under California Insurance Code §2051.5. RCV is typically the higher of the two values.
Reservation of rights: A carrier letter advising the insured that it is investigating the claim while reserving the right to deny coverage later under specified policy provisions. A reservation of rights is not a denial — it is a notice that one may follow. California rules require reservation letters to identify the specific provisions at issue.
Retroactive denial: A carrier denial issued after the carrier has begun handling the claim or made partial payments. California regulators view retroactive denials skeptically; when a carrier reverses course after months of investigation, the reversal can support a §790.03 claim-handling violation argument.
Rider: A synonym for endorsement — a written modification to the base policy form. Common riders on California homeowners policies include scheduled-personal-property riders for jewelry, art, and firearms, and water-backup riders for plumbing and sewer events.

S

Scope of damage: The complete itemized list of what was damaged, the unit of measure, the replacement specification, and the labor/material rate. The scope is the document a public adjuster builds; it is the document on which the entire valuation argument rests. A tight, defensible scope is the difference between a paid claim and a fight.
Smoke damage: Loss caused by combustion byproducts — soot, char, ash, polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds. After the 2025 LA fires and the Aliff ruling, California courts have held that smoke residue can constitute direct physical loss even where there is no visible char. CIH testing is the standard way to document smoke damage.
Sublimit: A reduced limit applied to a specific category of property or peril within an otherwise higher policy limit — for example, a $2,500 sublimit on jewelry inside a $250,000 contents limit, or a $10,000 mold sublimit. Sublimits often surprise policyholders; reading the declarations page and endorsements is the only way to find them in advance.
Subrogation: The carrier's right to step into the insured's shoes and pursue a third party who caused the loss after paying the claim. Common in California wildfire claims where utilities, contractors, or neighbors may have caused the loss. Subrogation recovery does not affect the insured's payment but can affect deductible reimbursement.

T

Total loss: A claim where the cost of repair exceeds the value of the property, or where the property is rendered economically unrecoverable. California "constructive total loss" rules generally require the carrier to pay the full dwelling limit when repair is not economically feasible. California Insurance Code §2051.5 also tightens carrier obligations on declared-disaster total losses.
Tort: A civil wrong giving rise to damages independent of contract. In California first-party insurance practice, the tort of bad faith is the doctrine that allows recovery of emotional-distress and Brandt-fee damages above policy limits. Distinguished from breach of contract, where damages are typically capped at policy benefits.

U

Underinsurance: A condition where the policy's dwelling limit is below the actual cost to rebuild. Endemic in California after rapid post-2020 construction inflation; many California homeowners on policies more than three years old are underinsured by 20–40% relative to current rebuild cost. Extended replacement cost endorsements partially offset this.
Unfair claim handling (§790.03): California Insurance Code §790.03(h) lists the practices that constitute unfair claim handling: misrepresenting policy provisions, failing to acknowledge or act on claims promptly, failing to adopt reasonable claim-handling standards, lowballing, denying claims without reasonable investigation, and others. The statutory framework that operationalizes the duty of good faith.
Umbrella policy: An excess-liability policy that sits above the liability limits on a homeowners or auto policy. Provides additional protection on third-party claims; typically does not affect first-party property coverage. California umbrella policies are a separate purchase from the underlying homeowners policy.

V

Vacancy clause: A policy provision reducing or eliminating coverage when the insured property has been vacant for more than a stated period (often 60 days). Significant for California rental property owners between tenants and for second-home owners. Vacancy clauses are a common partial-defense the carrier raises on water-damage and vandalism claims.
Valuation dispute: A disagreement about the amount of loss when coverage is not in dispute. The classic public-adjuster fight: the carrier acknowledges the loss is covered but disagrees on what it is worth. Resolved through documentation, supplements, the appraisal clause, and (rarely) litigation.

W

Wear and tear exclusion: A policy exclusion for damage caused by gradual deterioration rather than a discrete event. California carriers raise wear-and-tear on roof claims, plumbing claims, and foundation claims. The dispute usually turns on whether the loss is the discrete event or the underlying degraded condition; the efficient-proximate-cause rule often resolves it.
