3.3 Dwelling Perils, Conditions, and Endorsements

Perils, Exclusions, and the Coinsurance Condition

The Dwelling forms share the standard property exclusions: ordinance or law, earth movement, water damage (flood/sewer backup/surface water), power failure, neglect, war, nuclear hazard, and intentional loss. These are the same baseline exclusions tested across the property line; flood and earthquake require separate coverage or endorsement.

The most numerically tested condition is the 80% replacement-cost coinsurance provision on DP-2 and DP-3. To collect full replacement cost on a partial loss, the insured must carry insurance equal to at least 80% of the dwelling's full replacement cost at the time of loss.

The Coinsurance Formula

The loss-settlement formula is:

Recovery = (Amount carried / Amount required) x Loss, capped at the policy limit, minus deductible

Where Amount required = 80% x replacement cost value (RCV). If the insured meets the 80% requirement, losses are paid at full replacement cost up to the limit. If the insured is underinsured, the penalty applies on partial losses; total losses are paid up to the limit regardless.

Worked Numeric: Coinsurance Penalty

A dwelling has an RCV of $300,000. The insured carries only $180,000 on a DP-3. A covered fire causes a $60,000 partial loss. Deductible is $1,000.

• Amount required = 80% x $300,000 = $240,000.
• Did/Required ratio = $180,000 / $240,000 = 0.75.
• Indemnity before deductible = 0.75 x $60,000 = $45,000.
• Less $1,000 deductible = $44,000 paid.

The insured is penalized $15,000 for being underinsured. Had the insured carried at least $240,000, the loss would have been paid at the full $60,000 less deductible (RCV settlement).

Common Dwelling Endorsements

Trap: a base Dwelling policy provides no liability coverage — it is property-only. Liability and medical payments must be added by the Personal Liability Supplement endorsement. Theft is not a covered peril on the unendorsed DP forms.

Loss Settlement: RCV, ACV, and the Functional Option

Three valuation methods appear on the exam. Replacement cost (RCV) pays to repair/replace with like kind and quality with no deduction for depreciation — available on DP-2/DP-3 buildings when the 80% coinsurance test is met. Actual cash value (ACV) is RCV minus depreciation — the default on DP-1 and on personal property. Functional replacement cost pays to repair with modern, functionally equivalent (often cheaper) materials, used for older or obsolete dwellings.

Key trap: even on DP-2/DP-3, personal property (Coverage C) is settled at ACV, not replacement cost, unless a replacement-cost-on-contents endorsement is added. Only the building enjoys RCV by default.

Key Policy Conditions

The Dwelling conditions parallel the broader property line and are frequently tested:

• Duties after loss — give prompt notice, protect from further damage, prepare an inventory, and submit a signed proof of loss within 60 days when requested.
• Appraisal — either party may demand appraisal when they disagree on the amount of loss (not coverage); each picks an appraiser, the two select an umpire, and any two of the three agree.
• Subrogation — the insurer steps into the insured's rights against a responsible third party after paying a claim.
• Cancellation/nonrenewal — notice periods vary by state and reason; nonpayment usually allows shorter notice.
• Mortgage clause — protects the lender's interest even if the insured's act voids coverage.

Vacancy, Endorsements, and the Mechanics of a Dwelling Claim

Several conditions and add-ons decide whether a dwelling claim is paid in full.

The Vacancy Provision

Dwelling claims hinge on occupancy. If the dwelling is vacant beyond 60 consecutive days before a loss, coverage for certain perils - vandalism, glass breakage, water damage, theft attempt, and sprinkler leakage - is suspended, and other losses may be reduced. Landlords with turnover between tenants are the classic exposure.

Exam trap: Vacancy beyond 60 days suspends specific perils (notably vandalism and water damage). "Unoccupied" (furnished but no one living there) is not the same as "vacant" (empty of contents) - the exam tests the difference.

High-Value Dwelling Endorsements

• Broad Theft Coverage - adds on- and off-premises theft to a dwelling form.
• Dwelling Under Construction - adjusts limits as the structure's value rises.
• Automatic Increase in Insurance - raises Coverage A periodically to track inflation.
• Ordinance or Law - pays the extra cost to rebuild to current building codes, which the base form excludes.

Loss Settlement Recap and a Worked Number

Under DP-3 replacement-cost settlement, a dwelling insured to at least 80% of replacement cost collects full repair cost (no depreciation) up to the limit. A $250,000-replacement-cost home insured for $160,000 (only 64%, below 80%) suffering a $40,000 roof loss recovers the larger of ACV or (limit / 80% of value) x loss = ($160,000 / $200,000) x $40,000 = $32,000 before deductible - the under-insurance penalty in action.
