3.3 Dwelling Perils, Conditions, and Endorsements

Standard Exclusions

The dwelling forms exclude catastrophic, non-fortuitous, and maintenance losses. These apply to all three forms; the DP-3 open-perils promise is bounded by exactly this list.

Water-damage trap: A sudden burst pipe is covered on DP-2/DP-3, but flood, surface water, sewer or drain backup, and continuous seepage are excluded. Sewer backup can be bought back by endorsement.

Anti-Concurrent Causation

Flood, earthquake, and certain water losses are excluded even if a covered peril contributes to the same loss. A landslide triggered by heavy rain is still excluded earth movement, no matter the rain.

Duties After Loss

Coverage depends on the insured meeting policy conditions:

The Vacancy Provision

If the dwelling has been vacant for more than 60 consecutive days immediately before the loss:

• Vandalism and malicious mischief: no coverage at all.
• All other covered perils (fire, wind): payment reduced by 15%.

Example: a home empty and for sale for 75 days is vacant; vandals damage it, and the loss is not covered. A furnished home whose owner is hospitalized three months is unoccupied, and the provision does not strip coverage.

Coinsurance and Loss Settlement

Replacement cost on DP-2/DP-3 applies only if the insured carries at least 80% of the building's replacement cost; otherwise the insurer pays the greater of ACV or a proportional amount.

Formula: (Carried / Required) x Loss - Deductible = Payment.

Worked scenario: a building's replacement cost is $250,000. Required coverage is 80% = $200,000, but the landlord carries only $150,000. A covered fire causes $50,000 damage; deductible is $1,000.

1. Coinsurance factor: $150,000 / $200,000 = 0.75.
2. Apply to loss: 0.75 x $50,000 = $37,500.
3. Subtract deductible: $37,500 - $1,000 = $36,500 paid.

The landlord absorbs $13,500 as a coinsurance penalty. Note the order: the penalty is applied before the deductible.

Appraisal and the Mortgage Clause

Appraisal resolves a dispute over the amount of a covered loss: each party names an appraiser, the two pick an umpire, and agreement of any two binds. It never decides whether a loss is covered.

The Standard Mortgage Clause protects the mortgagee named on the Declarations. Loss is paid to insured and mortgagee as interests appear, and the mortgagee can still collect even if the insured's own coverage is voided by fraud, increased hazard, or neglect. The mortgagee gets separate cancellation notice (commonly 10 days for nonpayment).

Common Endorsements

Because the base forms leave deliberate gaps, endorsements are central to dwelling underwriting. When an exam question says "by endorsement," the base form alone would not respond.

Conditions Wrap-Up

A few more conditions recur on the exam:

• Other insurance: pro-rata sharing among policies covering the same loss.
• Subrogation: the insurer steps into the insured's rights against a negligent third party.
• Concealment or fraud: material misrepresentation voids coverage for the offending insured.
• Liberalization: if the insurer broadens a form at no charge during the period, the broader terms apply automatically.

Matching the three dwelling forms to perils

The dwelling forms parallel the causes-of-loss ladder. DP-1 (Basic) is named-peril covering fire, lightning, and internal explosion, with Extended Coverage (EC) and V&MM addable; it often settles at ACV. DP-2 (Broad) is named-peril but broader (adds the broad-form perils such as falling objects, weight of ice/snow, and accidental water discharge) and settles at replacement cost. DP-3 (Special) is open-peril on the dwelling and other structures (insurer must prove an exclusion) while personal property remains named-peril - the same structure as the HO-3.

Matching a fact pattern to DP-1/2/3 is the core dwelling exam skill.

Endorsements and conditions the DP needs

Because the base DP omits them, the heavily tested endorsements add liability, theft, and (on DP-1) replacement cost, and an Automatic Increase in Insurance endorsement keeps the Coverage A limit pace with inflation. Standard conditions mirror property forms: a coinsurance/loss-settlement condition on the DP-2/DP-3 conditions RC on carrying 80% of value, a vacancy limitation, and duties after loss including prompt notice and proof of loss. A frequent trap: an insured assumes a DP automatically covers a burglary or a guest injury - neither is covered without the theft or liability endorsement.
