3.3 Dwelling Perils, Conditions, and Endorsements

Covered Perils by Form

The exam expects you to recall which perils attach to which form. The progression is cumulative: DP-2 contains everything in DP-1 (with EC/V&MM built in) plus the broad perils, and DP-3 contains DP-2's content perils plus open-perils on the structure.

Common Exclusions

All dwelling forms exclude the standard property exclusions: ordinance or law, earth movement (earthquake, landslide, sinkhole collapse), water damage / flood, power failure (off-premises), neglect, war, nuclear hazard, and intentional loss. Flood and earthquake are insured separately (NFIP / DIC or DP 04 90 series earthquake endorsement). "Water damage" excludes flood, surface water, and sewer/drain backup unless backup is endorsed.

Key Policy Conditions

• Coinsurance (DP-2/DP-3): the 80% insurance-to-value requirement; underinsurance triggers the penalty formula in 3.2.
• Loss Settlement: ACV on DP-1; Replacement Cost on DP-2/DP-3 buildings when carried to 80%+ of RCV. Personal property settles on ACV unless RCV is endorsed.
• Duties After Loss: prompt notice, protect from further damage, prepare inventory, submit a signed and sworn proof of loss within 60 days of the insurer's request.
• Appraisal: when the insured and insurer disagree on the amount of loss (not coverage), either may demand appraisal; each picks a competent appraiser, and the two select an umpire. Agreement by any two sets the amount.
• Pair or Set / Loss to a Pair: the insurer may repair, replace, or pay the difference in ACV before and after the loss.
• Subrogation, Mortgagee Clause (Standard/Union mortgage clause protects the lender even if the insured's act voids coverage), Cancellation/Nonrenewal, Other Insurance (pro rata).

Frequently Tested Endorsements

• DP 04 11 – Personal Liability Supplement: adds Section II liability and medical payments to a Dwelling policy.
• Broad Theft Coverage / Limited Theft: adds on-premises (and broad/off-premises) theft to DP-2/DP-3. Not available on DP-1.
• Dwelling Under Construction: adjusts the Coverage A limit to track completed value as construction progresses.
• Automatic Increase in Insurance (inflation guard): raises Coverage A periodically to keep pace with replacement cost.
• Earthquake (DP 04 90 series) and Ordinance or Law endorsements buy back excluded exposures.

Worked Example — ACV Settlement on a DP-1

A DP-1 insures a roof with a replacement cost of $14,000 and an expected life of 20 years; the roof is 12 years old when a covered windstorm (EC endorsed) destroys it. Depreciation = 12/20 = 60%. ACV = $14,000 − (0.60 × $14,000) = $14,000 − $8,400 = $5,600.

With a $500 deductible, the DP-1 pays $5,100. Because the DP-1 settles on ACV, the insured absorbs the $8,400 of depreciation. The same roof on a DP-3 (RCV, carried to 80% of value) would pay the full $14,000 less the deductible = $13,500 — dramatically illustrating the cost of choosing the cheaper Basic form.

Reading the Exclusions Like the Exam Does

The dwelling exclusions follow the standard ISO anti-concurrent-causation logic on the broad/special forms: if an excluded peril (flood, earth movement) contributes to a loss "in any sequence," the resulting damage is excluded even if a covered peril also operated. This is why a windstorm-plus-flood hurricane loss splits between the dwelling policy (wind) and an NFIP policy (flood) — the dwelling form will not pay for the flood-caused portion.

Key exclusion distinctions tested heavily:

• Earth movement excludes earthquake, landslide, mudflow, and sinkhole; bought back by the earthquake endorsement.
• Water damage excludes flood, surface water, waves, sewer/drain backup, and underground water seepage — backup is added by a separate sewer/drain endorsement.
• Ordinance or law excludes the increased cost to rebuild to current code; added by the Ordinance or Law endorsement (often as a percentage of Coverage A).
• Power failure off the premises and neglect to protect property after a loss are excluded.

Mortgagee, Other Insurance, and Subrogation in Practice

The standard (union) mortgage clause protects the lender's interest even when the insured's own act or neglect would void coverage — the insurer pays the mortgagee and may then pursue its subrogation rights against the borrower. The Other Insurance condition makes the dwelling form pay pro rata when more than one policy applies. Subrogation lets the insurer recover from a negligent third party after paying the insured; the insured must not impair that right (e.g., by signing a waiver after a loss).

Other Coverages Built Into Dwelling Forms

Dwelling forms include several additional/other coverages that operate without reducing the Coverage A limit unless stated: debris removal, reasonable repairs, property removed from premises endangered by a covered peril (covered against direct loss for up to 30 days), fire department service charge (commonly $500), and collapse in the broad and special forms. The other structures coverage and a percentage for trees, shrubs, and plants also appear. Knowing these are automatic, and which ones carry their own sublimits, is frequently tested.

Key Dwelling Conditions

The dwelling conditions mirror commercial property logic: a pro-rata other-insurance clause, an appraisal clause for amount-of-loss disputes, subrogation, a mortgage clause protecting the lender, and loss settlement that pays replacement cost on the dwelling in DP-2 and DP-3 if the insured carries at least 80% of replacement cost, otherwise the larger of ACV or the coinsurance result. The liberalization clause automatically extends any broadening of coverage the insurer adopts without additional premium during the policy period.

Common Endorsements That Reshape the Dwelling Policy

Producers tailor dwelling policies with endorsements: Broad Theft Coverage (owner-occupants) and Limited Theft Coverage (non-owner-occupants) add theft the base forms omit; Dwelling Under Construction handles builders risk; the Automatic Increase in Insurance endorsement raises the limit periodically to track inflation; and Personal Liability and Premises Medical Payments endorsements bolt the liability coverages onto a dwelling policy that otherwise has none. Recognizing that liability is added, not built in, separates dwelling from homeowners.
