Homeowners insurance is often sold as if it covers "everything except" — with the everything-except section left as fine print. In practice, the exclusions in a standard US homeowners policy are substantial, and the gap between what a homeowner assumes is covered and what actually is covered produces a large share of claim disputes.

This article walks through the exclusions that most often appear in HO-3 (the most common form for single-family homes) and HO-5 policies, and the ways to close the gaps through endorsements or separate policies. It is general guidance, not insurance advice. The NAIC consumer glossary and the Insurance Information Institute's homeowners-insurance basics page are useful starting points.[¹][³]

The named-peril vs open-peril distinction

HO-3 — the most common US homeowners policy form — is a hybrid:

  • Coverage A (dwelling) and Coverage B (other structures) are written on an open-peril basis: damage is covered unless it is specifically excluded.
  • Coverage C (personal property) is written on a named-peril basis: damage is covered only if caused by one of the listed perils (fire, lightning, windstorm, hail, theft, vandalism, explosion, riot, aircraft, vehicles, smoke, and a few others).

HO-5 policies write both dwelling and personal property on an open-peril basis. HO-5 policies cost more and provide broader coverage, particularly for valuable personal property (electronics, jewellery, art).

The practical consequence: an HO-3 policyholder whose personal belongings are damaged by something not on the named-peril list may be surprised to find no coverage. A leak from a second-floor washing machine that damages the first-floor couch, for example, involves a peril (accidental water discharge) that may be covered for the dwelling (Coverage A, open peril) but may not be covered for the couch (Coverage C, named peril).

Flood is excluded

Every standard US homeowners policy excludes flood damage. Flood is defined — generally — as rising water from a natural source (river, lake, ocean), heavy rainfall that overflows drainage, or mudflow.

Flood coverage requires a separate policy, typically from the National Flood Insurance Program (NFIP) administered by FEMA.[²] Private flood insurance is also available in many markets. A homeowner in a flood zone usually has a mortgage requirement to carry flood insurance; a homeowner outside a flood zone often does not but may still want coverage because flood events happen outside designated zones as well.

A common confusion: water damage from a burst pipe or a leaking roof is not "flood" — it is "water damage from internal sources," which IS typically covered by a standard homeowners policy (subject to specific exclusions around long-term seepage). The flood exclusion is specifically about external surface water.

Earthquake is excluded

Standard homeowners policies exclude earthquake damage. Coverage is available through separate earthquake policies or endorsements, most commonly from state-sponsored programs (California Earthquake Authority) or specialty carriers.

Like flood, the earthquake exclusion has subtle boundaries:

  • Damage caused by an earthquake-triggered fire is typically covered because fire is a named peril for personal property and a non-excluded peril for the dwelling on an open-peril policy — the separate "fire following" doctrine treats the fire as an independent cause.
  • Earthquake sprinkler leakage may or may not be covered depending on the form.
  • Landslides and earth movement are typically excluded, whether or not they were earthquake-triggered.

Maintenance, wear and tear, and neglect

Homeowners policies are designed to cover sudden and accidental losses, not gradual deterioration. The maintenance and wear-and-tear exclusion is one of the most common reasons for claim denial.

Typical examples of excluded maintenance issues:

  • Leaking roof due to age (versus a sudden storm-damaged roof).
  • Mould from long-term humidity (versus mould from a specific water-damage event).
  • Termite damage.
  • Carpet wear, paint deterioration, fading.
  • Deferred maintenance causing subsequent damage (for example, a failure to replace a 30-year-old water heater that eventually fails and floods the basement — the resulting water damage may be covered, but the water heater itself and certain direct consequences may not).

The maintenance exclusion is a frequent source of dispute because the line between sudden and gradual is fact-specific. A roof that leaks after a windstorm may look similar to a roof that leaks from age; the adjuster's investigation and the policy's specific language determine which coverage applies.

Business activities

Most homeowners policies exclude property used primarily for business. A dedicated home office with equipment above a specified threshold (often $2,500) may need a business endorsement. A home that is used to run a small business — childcare, salon services, e-commerce fulfilment — may not be covered for the business assets or liability arising from the business activity.

Endorsements and standalone policies address this:

  • Home-based business endorsement. Extends limited coverage to business property and liability for a qualifying home-based business.
  • Business owner's policy (BOP). A standalone small-business policy for businesses that outgrow home-based-business endorsement thresholds.
  • Short-term rental endorsement. Addresses the specific gap for homeowners who rent their home via Airbnb or similar platforms.

Intentional acts and criminal activity

Intentional damage by the insured is excluded. Damage caused by criminal activity of the insured or a household member is excluded. These exclusions are enforced even when the homeowner's co-insureds (an innocent spouse, for example) were not involved in the intentional act — though courts in some states narrow the exclusion to preserve innocent-co-insured coverage.

Motor vehicles

Homeowners policies generally exclude damage to motor vehicles. Coverage for motor vehicles comes from auto policies. The narrow exception: motor vehicles not required to be licensed (riding lawnmowers, certain golf carts) are typically covered as personal property.

Acts of war and nuclear hazard

Every standard homeowners policy excludes war, insurrection, and nuclear hazard. These exclusions are rarely invoked in practice but are uniformly in the policy forms.

Government action

Confiscation, destruction, or seizure by civil authority is excluded. Damage caused by a government-ordered demolition (after a fire in an adjoining structure, for example) may be excluded unless a specific endorsement or separate coverage applies.

Animal damage, insects, and vermin

Damage caused by household pets, rodents, birds, and insects is typically excluded. A dog that chews the carpet, termites that eat the beams, or mice that nest in the wiring are all generally outside coverage. One exception: bats and squirrels that enter through storm damage may have a narrow coverage window depending on the specific cause of entry.

Power failure and service interruption

Loss caused by power failure that originates off the insured premises is typically excluded. Spoiled food in a refrigerator after a neighbourhood-wide outage, for example, is usually not covered unless a separate food-spoilage endorsement is added.

Liability exclusions

The liability section of a homeowners policy has its own set of exclusions. The most frequent:

  • Business pursuits. Injuries arising from the insured's business activities are typically not covered under the homeowners liability section.
  • Motor vehicle liability. Auto policies cover this.
  • Intentional acts. Intentional infliction of harm is not covered.
  • Dog bites (sometimes). Some policies exclude specific dog breeds or all dogs; others cover the first bite and then exclude the dog after a bite incident.
  • Swimming pools and trampolines (sometimes). Some policies exclude these attractive nuisances entirely; others require safety features (fencing, covers) before coverage applies.
  • Professional services. A doctor's or dentist's home-office professional liability is not covered under the homeowners liability section.

Endorsements that close common gaps

Several endorsements close the most common coverage gaps:

  • Scheduled personal property endorsement. Lists specific high-value items (jewellery, art, cameras, musical instruments) with explicit limits that exceed the base policy's per-item and per-category sub-limits.
  • Water backup and sump-pump overflow endorsement. Adds coverage for sewer backup and sump-pump failure, which are typically excluded under the base policy.
  • Service-line endorsement. Covers damage to underground utility lines that run from the street to the house.
  • Ordinance-or-law endorsement. Covers the additional cost of rebuilding to current building codes after a covered loss, which the base policy often caps.
  • Identity theft endorsement. Adds expense coverage for identity-theft resolution.
  • Extended dwelling replacement cost endorsement. Adds a percentage buffer (typically 25 to 50 percent) above the Coverage A limit for rebuilding when replacement costs exceed the policy limit.

Reading the policy form

The dec page summarises coverages and limits. The policy form — often 40 or more pages — contains the definitions, exclusions, and conditions. When a loss happens, the adjuster reads the policy form, not the dec page. A homeowner considering a coverage question is typically best served by reading the exclusions section of the form before assuming a loss is covered.

Where DocAssessment fits

DocAssessment extracts homeowners policy declarations deterministically — coverages, limits, endorsements, deductibles — before any AI model sees the document. The methodology page describes the seven-step pipeline. For a homeowners policy, the extraction surfaces the form type (HO-3, HO-5), the Coverage A/B/C/D limits, deductibles, and attached endorsements, and flags gaps where common risks (flood, earthquake, water backup, identity theft) are not addressed by separate coverage or endorsements.

The analysis is informational. For specific coverage questions, adjusters and insurance agents are the right next stops; for a disputed claim, an insurance-coverage attorney or the state department of insurance complaint process applies.
