3.3 Dwelling Perils, Conditions, and Endorsements

Perils, Exclusions, and Loss Settlement

Beyond the form/peril structure, DP exam items focus on policy conditions that govern how a claim is paid. Two conditions dominate: the loss settlement (coinsurance) condition and the valuation basis (ACV vs. replacement cost).

The DP-2 and DP-3 building loss settlement clause requires the insured to carry at least 80% of the replacement cost to collect replacement cost on a partial loss. Carry less and the insurer pays the greater of (a) ACV of the damaged part, or (b) a proportion determined by the coinsurance formula. DP-1 buildings are settled at ACV regardless.

Worked Coinsurance Example

A DP-3 dwelling has a replacement cost of $400,000. The 80% coinsurance requirement means the insured should carry 0.80 x $400,000 = $320,000. The insured actually carries only $240,000. A partial fire loss costs $50,000 to repair (RC).

Payment = (Did carry / Should carry) x Loss = ($240,000 / $320,000) x $50,000 = 0.75 x $50,000 = $37,500, less any deductible. Because the insured was underinsured (75% of requirement), the insurer pays 75% of the loss on the replacement-cost track. The insured absorbs the $12,500 coinsurance penalty plus the deductible.

ACV vs. Replacement Cost

• Actual Cash Value (ACV) = replacement cost minus depreciation. If a 10-year-old roof with a 20-year life and a $20,000 replacement cost is destroyed, ACV = $20,000 x (10 remaining / 20 total) = $10,000.
• Replacement Cost pays to repair/replace with like kind and quality without depreciation, subject to the 80% coinsurance condition and the policy limit.

DP-1 settles buildings and contents at ACV. DP-2/DP-3 settle the building at replacement cost (if coinsurance is met) but personal property remains ACV unless a replacement-cost endorsement is added.

Common Conditions and Endorsements

Key conditions the exam tests:

• Insurable interest limits recovery to the insured's financial interest.
• Other insurance - DP pays its pro rata share if other coverage exists.
• Subrogation - the insurer assumes the insured's recovery rights after paying.
• Mortgage clause - protects the lender's interest even if the insured's act voids coverage.
• Vacancy - V&MM and certain water/glass losses are suspended after 60 consecutive days of vacancy.

Why the Greater-Of Rule Matters

The loss settlement condition pays the greater of the ACV of the damaged part or the coinsurance-formula amount—then never more than the policy limit or the actual cost to repair. So an underinsured insured still receives at least ACV. In the $400,000 example above, if ACV of the damaged portion were $40,000 (higher than the $37,500 coinsurance figure), the insurer would pay the $40,000 ACV instead. Test writers use this to check whether you remember the floor is ACV, not zero.

Also note the small-loss exception: many DP loss settlement clauses pay replacement cost in full for partial losses under $2,500 (or a stated figure) without applying the proportional penalty, easing claims for minor damage.

Exclusions Common to All DP Forms

Even the open-peril DP-3 carries standard exclusions. Memorize the recurring list: ordinance or law, earth movement (earthquake), flood/water damage from outside, power failure off-premises, neglect, war, nuclear hazard, and intentional loss. DP-3 adds open-peril-specific exclusions such as wear and tear, deterioration, mechanical breakdown, latent defect, smog/rust/mold, settling, and damage by insects/birds/rodents/domestic animals.

Trap: a DP-3 covers the dwelling 'all-risk,' but if the cause traces to one of these excluded perils—say a foundation cracks from earth movement—the loss is denied despite the open-peril language. Ensuing-loss provisions may restore coverage for a separate covered peril that results (e.g., a fire that follows an excluded event).

Key Dwelling Conditions

Several DP conditions appear on the exam:

• Loss settlement — DP-1 pays ACV; DP-2/DP-3 pay replacement cost on the dwelling subject to the 80% insure-to-value condition.
• Other insurance — pro rata sharing when more than one policy applies.
• Mortgage clause — protects the lender's interest even if the insured's act voids coverage.
• Subrogation — preserved unless waived in writing before a loss.

Frequently Tested Endorsements

Ordinance or Law: A Worked Point

A 40-year-old dwelling suffers major fire damage; current code now requires updated wiring and an upgraded foundation costing an extra $25,000 beyond simple replacement. Without an Ordinance or Law endorsement, the policy pays only to restore the building to its prior condition and excludes the code-upgrade cost. With the endorsement (often expressed as a percentage of Coverage A), that extra demolition-and-rebuild-to-code cost is covered. The exam uses older-home scenarios precisely because the ordinance-or-law exclusion is a standard gap many insureds discover only at claim time.
