4.3 Section I Perils Insured Against and Exclusions

Key Takeaways

  • The basic peril list (HO-8) is fire/allied perils; the broad list (HO-2, HO-3 contents) adds water-discharge, ice weight, falling objects, and appliance perils.
  • Open-peril forms cover all risk except stated exclusions; no peril list applies.
  • All forms exclude ordinance/law, earth movement, water (flood/backup/seepage), power failure, neglect, war, nuclear, intentional loss, and governmental action.
  • Anti-concurrent causation excludes flood/earth-movement losses even when a covered peril contributes concurrently.
  • Sudden/accidental pipe discharge is covered; flood, gradual seepage, and sewer backup are excluded absent endorsement.

Named Peril Lists: Basic vs. Broad

Named-peril Homeowners forms draw from two lists. The basic list (used by HO-8 and the lowest-tier dwelling coverage) contains the original fire-and-allied perils. The broad list (used by HO-2 and for Coverage C on the HO-3) adds several water-related and falling-object perils. Open-peril forms (HO-3 dwelling, HO-5 throughout) do not use a list at all - they cover all risk except stated exclusions.

Basic named perils (HO-8): fire and lightning; windstorm and hail; explosion; riot and civil commotion; aircraft; vehicles; smoke; vandalism and malicious mischief; theft; volcanic eruption.

Broad list adds (HO-2, and Coverage C of HO-3): falling objects; weight of ice, snow, or sleet; accidental discharge or overflow of water or steam; sudden and accidental tearing apart/cracking/burning/bulging of a heating or AC system; freezing of plumbing; sudden and accidental damage from artificially generated electrical current. The mnemonic "the broad form adds the perils a homeowner can suffer from inside the house" helps recall the water and appliance perils.

Section I Exclusions (Apply to ALL Forms)

Even open-peril forms exclude these. The exam tests recognition that these losses are not covered regardless of whether the form is named or open peril:

ExclusionNotes / Trap
Ordinance or lawCost to comply with building codes; partially restored by 10% Additional Coverage
Earth movementEarthquake, landslide, sinkhole - needs separate endorsement/policy
Water damageFlood, surface water, sewer/drain backup - flood needs NFIP/private flood; backup is endorsable
Power failureOff-premises power interruption
NeglectFailure to protect property after a loss
WarIncluding undeclared war and warlike acts
Nuclear hazardReaction, radiation, contamination
Intentional lossBy or at the direction of an insured
Governmental actionSeizure or destruction by order

These eight to nine exclusions are sometimes recalled with the mnemonic that they are the perils too catastrophic or controllable to be insured in a standard homeowners contract.

Anti-Concurrent Causation

The water and earth-movement exclusions include an anti-concurrent causation (ACC) lead-in: the loss is excluded "regardless of any other cause or event contributing concurrently or in any sequence to the loss." This means if an excluded peril (e.g., flood) combines with a covered peril (e.g., wind) to cause the same damage, the entire loss is excluded - the insurer does not have to apportion. This is a major exam concept and the reason flood and earthquake must be insured separately.

Exam trap: A burst pipe causing sudden water discharge IS covered (it is a broad-form peril). But continuous or repeated seepage over weeks, flood (surface water), and sewer backup (absent endorsement) are all excluded. Distinguish sudden/accidental discharge (covered) from gradual seepage and external water (excluded).

Theft and Other Peril Restrictions

The theft peril carries its own exclusions even on open-peril forms. Theft is not covered when committed by an insured, theft in or from a dwelling under construction (until completed and occupied), and theft from that part of a residence rented to someone who is not an insured. Off-premises theft of property at a residence the insured does not occupy is also restricted. These carve-outs explain why a tenant's theft of the landlord's furnishings, or jewelry stolen during a remodel of an unoccupied new build, may be denied.

Vandalism and glass breakage are suspended once a dwelling has been vacant for more than 60 consecutive days before the loss (the vacancy condition discussed earlier). Mold, fungus, and wet rot are excluded except a limited amount when resulting from a covered water loss. Birds, vermin, rodents, and insects are excluded as wear-and-tear type causes.

Exam trap: Distinguish vacant (no occupant and no contents) from unoccupied (furnished but temporarily empty). Only true vacancy beyond the stated period triggers the suspension of vandalism, glass, and certain water perils - a frequently misread distinction on licensing exams.

Section I Exclusions Common to All HO Forms

Every Homeowners form excludes the same core perils through the anti-concurrent-causation lead-in: ordinance or law, earth movement (earthquake/landslide/sinkhole), water damage (flood, surface water, sewer/drain backup, subsurface water), power failure (off-premises), neglect, war, nuclear hazard, intentional loss, and governmental action. The anti-concurrent wording means if an excluded peril (flood) combines with a covered peril (wind) to cause a loss, the entire loss is excluded — the most-tested Section I trap, especially after hurricanes where wind and flood overlap.

Sewer/drain backup and earthquake are added only by endorsement.

Covered vs. Excluded Water and the Hurricane Trap

Water losses divide sharply: accidental discharge from a plumbing, heating, or appliance system inside the dwelling is covered; flood, surface water, and sewer/drain backup are excluded without endorsement.

After a hurricane, wind-driven rain entering through a wind-created opening is generally covered as wind damage, but storm surge and rising water are flood — excluded and payable only by the NFIP. Because anti-concurrent causation excludes the entire loss when flood combines with a covered peril, adjusters and exam questions parse exactly which water caused which damage. Sewer backup is added by the water back-up endorsement.
