4.3 Section I Perils Insured Against and Exclusions
Key Takeaways
- Named-perils forms require proving a listed peril; open-perils forms cover all direct loss unless excluded.
- The basic list (fire, lightning, wind/hail, explosion, riot, aircraft, vehicles, smoke, vandalism, theft) underlies every form.
- Broad form adds falling objects, weight of ice/snow, water discharge, HVAC cracking, freezing, electrical, and volcanic eruption.
- Flood and earth movement are always excluded; flood needs NFIP, earthquake needs HO 04 54, sewer backup needs HO 04 95.
- Anti-concurrent causation excludes a loss if an excluded peril contributes in any sequence with a covered one.
Perils Insured Against
Section I defines what causes of loss are covered. The structure depends on the form. Named-perils coverage (the basic and broad lists, and Coverage C on most forms) pays only when one of the listed perils causes the loss. Open-perils coverage (HO-3/HO-5 dwelling; HO-5 contents) pays for any direct physical loss unless excluded. Knowing the two named-perils lists is essential exam content.
The Basic and Broad Named-Perils Lists
| Basic-Named Perils (also in DP-1) | Added by Broad Form |
|---|---|
| Fire or lightning | Falling objects |
| Windstorm or hail | Weight of ice, snow, sleet |
| Explosion | Accidental discharge/overflow of water/steam |
| Riot or civil commotion | Sudden tearing/cracking of heating/AC systems |
| Aircraft | Freezing of plumbing/HVAC |
| Vehicles | Sudden artificially generated electrical damage |
| Smoke | Volcanic eruption |
| Vandalism or malicious mischief | |
| Theft |
Memory aid for the basic list: "We Have Some Very Eager Adjusters Reviewing Vandalism, Smoke, and Lightning." The broad list adds the second column. The HO-2 uses the full broad list; HO-8 uses a narrowed basic list.
Note how the HO-3 mixes bases: the dwelling (Coverage A and B) is open perils, so a falling tree or a frozen pipe is covered unless excluded, while contents (Coverage C) stay on the broad named-perils list. That is why a question about contents damaged by an unusual cause (say, a meteor) may hinge on whether "falling objects" is a listed broad peril — it is — whereas the same cause hitting the roof is simply open-perils covered.
Section I Exclusions
Exclusions apply to all Section I coverages, including open-perils forms. The classic exam exclusions are:
- Ordinance or Law (cost to comply with building codes when rebuilding)
- Earth Movement (earthquake, landslide, sinkhole) — needs a separate policy or endorsement
- Water Damage (flood, surface water, sewer/drain backup) — flood needs the NFIP
- Power Failure (off-premises)
- Neglect (failure to protect property after a loss)
- War, Nuclear Hazard, Intentional Loss
- Governmental Action
A frequently tested point: the anti-concurrent causation language means that if an excluded peril (e.g., flood) contributes to a loss in any sequence with a covered peril, the loss is excluded. Sewer/drain backup can be added back by the HO 04 95 endorsement; water/sewer backup is NOT the same as flood.
Exclusions matter most on open-perils forms, because there the policy covers everything except what is excluded. On a named-perils form an uncovered cause is simply absent from the list. So an exam item that gives an HO-5 (open perils) and an unusual loss is really asking, "Is this on the exclusion list?" — if it is not excluded, it is covered.
Trap List: Common Exam Pitfalls
- Flood vs. water backup — flood (rising surface water) is always excluded and requires NFIP; sewer/sump backup can be endorsed onto the HO policy.
- Earthquake is excluded and bought back by the HO 04 54 endorsement.
- Mold is generally excluded or sub-limited; it is covered only when resulting from a covered water peril.
- Wear and tear, deterioration, rust, rot, settling, and infestation are excluded maintenance perils on every form.
- Frozen pipes are covered ONLY if the insured used reasonable care to maintain heat or shut off and drain the system in a vacant dwelling.
- On open-perils forms, theft from a dwelling under construction and continuous/repeated seepage are specifically excluded.
The split between sudden water discharge (covered broad peril) and flood/surface water (excluded) and seepage (excluded as gradual) generates many exam items. A burst supply line that floods the kitchen overnight is a covered accidental discharge; a slow leak under the sink that rots the cabinet over months is excluded seepage; a storm-swollen creek entering the basement is excluded flood. Train yourself to spot the keywords sudden and accidental (covered) versus continuous, repeated, gradual, or rising surface water (excluded).
The Open-Peril (HO-3/HO-5) Difference
On HO-3 the dwelling and other structures are open-peril, so the insurer must prove an exclusion to deny; contents remain named-peril (broad list). HO-5 extends open-peril to contents as well. This is why a mysterious-disappearance or accidental-spill loss to personal property is typically denied under HO-3 but may be covered under HO-5. The exam loves a fact pattern where the same loss is covered under HO-5 but excluded under HO-3 contents.
Concurrent Causation and the Tested Exclusions
The standard HO exclusions read with an anti-concurrent-causation lead-in ("we do not insure for loss ... regardless of any other cause or event contributing concurrently or in any sequence"). The big eight excluded perils are: ordinance or law, earth movement, water damage (flood/surface water/sewer backup without endorsement), power failure (off-premises), neglect, war, nuclear hazard, and intentional loss. Many of these have ensuing-loss exceptions — for example, an excluded cause that sets off a fire still has the fire covered.
Pitfall Recap
| Loss | HO-3 result |
|---|---|
| Flood from a river | Excluded (need NFIP) |
| Sewer/drain backup | Excluded unless water-backup endorsement |
| Frozen pipes in a vacant home | Excluded if heat not maintained / water not shut off |
| Mold following a covered water loss | Limited sublimit, not full coverage |
| Earthquake | Excluded; needs endorsement |
Heavy rain causes a nearby river to overflow, and rising water enters the insured's home. The HO-3 is in force with no endorsements. How is this loss handled?
A windstorm tears off shingles, and an inspector finds the roof deck was already rotted from years of leaking. The insurer pays to replace shingles but denies the cost to replace the rotted deck. Which exclusion supports denying the deck?
