3.3 Dwelling Perils, Conditions, and Endorsements

Perils Insured Against

The perils escalate across the three forms. Candidates should memorize the boundaries.

• DP-1 base: Fire, Lightning, Internal Explosion.
• DP-1 with Extended Coverage (EC): adds Windstorm/Hail, Explosion, Riot/Civil Commotion, Aircraft, Vehicles, Smoke, Volcanic Eruption (mnemonic WC SHAVERS variants).
• DP-1 with V&MM: adds Vandalism and Malicious Mischief.
• DP-2/DP-3 named perils add the broad group: weight of ice/snow/sleet, accidental water discharge, freezing, falling objects, building glass breakage, sudden electrical damage, and tearing apart/cracking/burning/bulging of heating or AC systems.

DP-3 then writes the structure open-peril, so any cause not excluded is covered — shifting the burden of proof to the insurer.

A recurring trap is that even DP-3's open-peril Coverage A still excludes specific causes such as wear and tear, marring, deterioration, mechanical breakdown, rust, mold, vermin, and settling. "Open peril" does not mean "everything"; it means everything except the listed exclusions and a handful of named limitations. On contents, all three forms remain named-peril, so a contents loss must still trace to a peril on the broad list. Candidates who assume DP-3 covers gradual or maintenance-type damage will miss these questions.

Standard Exclusions

All dwelling forms exclude the same broad categories regardless of open or named peril. The classic exclusions:

• Ordinance or Law, Earth Movement (earthquake, landslide, sinkhole), Government Action, Power Failure (off-premises), Neglect, War, Nuclear Hazard, and Intentional Loss.
• Water Damage — flood, surface water, sewer/drain backup, and water below the surface are excluded; this is why flood coverage requires the NFIP or a private flood policy.

Many exclusions can be bought back: Earthquake by the DP 04 26 endorsement, Ordinance or Law by DP 04 71, and water/sewer backup by a backup endorsement. Earthquake endorsements carry a separate percentage deductible (commonly 5%-25% of the dwelling limit), not a flat dollar deductible.

Key Policy Conditions

The Mortgage Clause protects the lienholder's interest even if the insured's act would void coverage, and entitles the mortgagee to separate notice of cancellation.

The other-insurance and pair-or-set conditions also surface on the exam. When more than one policy covers the same loss, the dwelling form pays only its pro-rata share of the total insurance in force. Under the pair-or-set condition, the insurer may either restore the set or pay the difference between the set's value before and after the loss — it is not obligated to pay as if the whole set were destroyed when only one item is damaged. Recognizing that these conditions cap recovery often separates two close answer choices.

Common Endorsements

Because the dwelling forms are bare property contracts, endorsements are heavily tested:

• DP 04 01 / Personal Liability Supplement — adds Coverage L (liability) and Coverage M (medical payments), turning the property-only DP into a package similar to a HO.
• DP 04 11 Additional Insured — names a person with an insurable interest.
• DP 04 26 Broad Theft Coverage — adds on-premises and off-premises theft for owner-occupants (theft is otherwise excluded).
• DP 04 73 Ordinance or Law and Replacement Cost on Contents endorsements.

Note a frequent trap: theft is not covered in any base dwelling form; it must be endorsed, and broad theft is generally only available to owner-occupants, not investor landlords.

The Exclusions That Survive Even Open-Peril Forms

Even the broadest DP-3 open-peril form carries the standard property exclusions: ordinance or law, earth movement, water damage (flood, surface water, sewer backup), power failure, neglect, war, nuclear hazard, and intentional loss. Several can be added back: an Ordinance or Law endorsement, a Water Backup endorsement, and a separate flood policy through the NFIP. The exam reliably asks which standard exclusion forces the insured to buy a separate flood policy — the answer flows from the water-damage exclusion.

Conditions and High-Frequency Endorsements

The DP form's conditions mirror other property forms: insurable interest, duties after loss, appraisal, the standard mortgage clause, subrogation, and a pro-rata other-insurance provision. Tested endorsements include:

• Automatic Increase in Insurance — raises the dwelling limit periodically to track inflation.
• Dwelling Under Construction — adjusts the limit as the structure rises in value (builders risk concept).
• Broad Theft Coverage — adds theft to DP-2/DP-3 for an owner-occupant.
• Personal Liability and Medical Payments — bolt Section II onto the property-only base form.

The vacancy rules matter on rentals: extended vacancy suspends vandalism and certain water losses.

Dwelling Peril Tiers and a Theft Caution

The three dwelling forms map to peril tiers: DP-1 covers fire, lightning, and internal explosion, with Extended Coverage (EC) perils (windstorm, hail, aircraft, vehicles, riot, smoke, volcanic eruption) and V&MM available for extra premium.

DP-2 is broad named-peril and DP-3 is open-peril on the dwelling. None of the unendorsed dwelling forms includes theft for an investor/landlord by default; theft must be added by the Broad Theft Coverage endorsement, and even then it favors an owner-occupant. This is the most common dwelling-coverage trap: assuming theft is automatic when it is not.
