Property Insurance Claims Glossary of Key Terms

Property insurance claims involve a specialized vocabulary that directly shapes how coverage is interpreted, disputes are resolved, and settlements are calculated. This page defines the core terms used across residential, commercial, and catastrophe property claims in the United States. Familiarity with these definitions is essential for understanding policy language, adjuster communications, and regulatory filings under state insurance codes.

Definition and scope

Property insurance terminology draws from three overlapping sources: policy contract language standardized by the Insurance Services Office (ISO), state insurance codes administered by individual state departments of insurance, and federal guidelines issued through agencies such as the Federal Emergency Management Agency (FEMA) for flood-specific claims under the National Flood Insurance Program (NFIP).

The glossary below covers terms relevant to first-party property claims — those filed by the policyholder against their own insurer — as distinct from third-party liability claims. For a structured comparison of these two claim types, see Property Claims vs. Liability Claims.

Core definitional terms:

• Peril — A specific cause of loss named or excluded in a policy. Named-peril policies cover only listed events (fire, theft, windstorm); open-peril (or "all-risk") policies cover all causes not explicitly excluded.
• Occurrence — An event or continuous condition that triggers coverage. Defined distinctly from "accident" in many commercial forms.
• Loss — The reduction in value or physical damage to insured property resulting from a covered peril.
• Claim — A formal demand submitted to the insurer requesting payment for a covered loss.
• Policy Period — The dates between which a covered loss must occur for the policy to respond. Losses outside this window are not covered regardless of when they are discovered.
• Declarations Page (Dec Page) — The summary section of a policy listing named insured, property address, coverage amounts, deductibles, and policy number. It is the primary reference document during filing a property insurance claim.

How it works

Understanding how these terms interact requires tracing them through the claims process in sequence. The process typically moves through four phases: loss occurrence, claim filing, adjustment, and settlement.

1. Loss occurrence — A covered peril damages insured property during the policy period.
2. Notice of loss — The policyholder notifies the insurer, triggering the insurer's duty to investigate. insurance.ca.gov/01-consumers/105-type/95-guides/03-res/upload/CA-Fair-Claims-Settlements-Practices-Regulations.pdf)).
3. Adjustment — A licensed adjuster evaluates the loss. Key terms at this stage include:
4. Actual Cash Value (ACV) — Replacement cost minus depreciation. See the detailed breakdown at Actual Cash Value vs. Replacement Cost Claims.
5. Replacement Cost Value (RCV) — The cost to repair or replace damaged property with like kind and quality at current prices, without depreciation deduction.
6. Depreciation — A reduction in value based on age, condition, and useful life of the damaged item.
7. Holdback — The portion of RCV withheld until repairs are completed and receipts submitted.
8. Settlement — Payment issued after deductibles, depreciation (if ACV policy), and coverage limits are applied. See Property Claim Settlement Process for procedural detail.

Deductible types operate at this stage and materially affect net payment:

• Flat deductible — A fixed dollar amount subtracted from each claim payment.
• Percentage deductible — A percentage of the insured dwelling value, common for wind and hurricane coverage. On a $400,000 home with a 2% wind deductible, the out-of-pocket threshold is $8,000 before the insurer pays.
• Disappearing deductible — Reduces to zero as loss severity increases; less common in modern residential forms.

The full taxonomy of deductible structures is covered in Insurance Deductible Types for Property Claims.

Common scenarios

Specific terms appear with higher frequency depending on the type of loss. The following scenarios illustrate term application in context.

Water damage claims involve terms such as:
- Sudden and accidental — The qualifying standard for most covered water losses; burst pipes typically qualify, while slow leaks often do not.
- Flood exclusion — Standard homeowners policies (ISO HO-3 form) exclude flood damage by definition. Flood coverage requires a separate NFIP or private flood policy. Details appear in Water Damage Property Claims.

Fire damage claims commonly involve:
- Total loss — When repair cost exceeds the insured value or a threshold percentage (often 75–80% of insured value, varying by state) of the structure's value.
- Debris removal — A coverage sublimit for clearing damaged materials. Many ISO forms cap this at 5% of the Coverage A limit.

Catastrophe and natural disaster claims introduce:
- CAT code — An internal insurer designation tracking claims from a declared catastrophe event. FEMA disaster declarations affect NFIP claim processing and federal assistance eligibility.
- Proof of Loss — A sworn statement submitted by the policyholder attesting to the nature and dollar amount of a loss. Required under most policies within 60 days of loss under NFIP rules (44 C.F.R. § 61.13). See also Proof of Loss Statement Guide.

Decision boundaries

Certain terms define the boundary between covered and excluded losses, and misapplication of these terms is a primary driver of claim disputes documented by the National Association of Insurance Commissioners (NAIC).

Key boundary terms:

• Exclusion — A policy provision that removes specific perils, property types, or loss causes from coverage. An exclusion must be clearly stated to be enforceable under most state insurance codes. For full coverage of exclusion categories, see Coverage Exclusions in Property Claims.
• Concurrent causation — When two perils combine to produce a loss and one is excluded, policy language determines whether the entire loss is excluded or only the excluded peril's contribution. Anti-concurrent causation clauses (found in ISO HO-3 post-1991 editions) exclude the entire loss if an excluded peril contributes in any sequence.
• Ensuing loss — Covered damage that results from an excluded cause. For example, a fire ignited by an excluded earth movement event may still be covered under the fire peril.
• Sue and Labor clause — A provision requiring policyholders to take reasonable steps to prevent further damage after a loss. Failure to comply can reduce or void a claim. This directly connects to Temporary Repairs and Property Claims.
• Subrogation — The insurer's legal right to recover claim payments from a liable third party after compensating the insured. Explained in full at Property Insurance Subrogation Explained.
• Bad faith — A legal standard applied when an insurer unreasonably denies or delays a valid claim. State tort law governs bad faith standards; penalties and available remedies vary by jurisdiction. The NAIC Model Unfair Claims Settlement Practices Act provides the baseline regulatory framework adopted in modified form by 46 states (NAIC Model Laws).
