3.3 Dwelling Perils, Conditions, and Endorsements

Perils and the Open- vs Named-Peril Burden of Proof

Under named-peril forms (DP-1, DP-2, all DP contents), the insured must prove the loss was caused by a listed peril. Under open-peril coverage (DP-3 building), the insurer must prove an exclusion applies to deny the claim. This shift in burden of proof is a heavily tested concept.

Common DP exclusions across forms include Ordinance or Law, Earth Movement, Water Damage (flood, surface water, sewer backup), Power Failure, Neglect, War, Nuclear Hazard, and Intentional Loss. Wear and tear, deterioration, mechanical breakdown, and birds/vermin/rodents/insects are also excluded — these often surface as DP-3 "open peril" traps where candidates assume everything is covered.

Loss Settlement and Coinsurance Math

DP-2 and DP-3 settle building losses at Replacement Cost if the insured carries at least 80% of replacement cost at the time of loss. If carried below 80%, the insurer pays the greater of ACV or the coinsurance formula:

Payment = (Carried ÷ Required) × Loss − Deductible

Worked example: A DP-3 dwelling has a replacement cost of $400,000. Required to avoid penalty = 80% × $400,000 = $320,000. The insured carries only $240,000. A partial fire loss is $100,000; deductible is $1,000.

• Coinsurance ratio = $240,000 ÷ $320,000 = 0.75
• Indemnity = 0.75 × $100,000 = $75,000
• Less deductible: $75,000 − $1,000 = $74,000 paid

The insured absorbs the $25,000 penalty plus the deductible because of underinsurance.

ACV vs Replacement Cost — Worked Example

A roof with a 20-year life is 12 years old when a windstorm destroys it. Replacement cost = $18,000.

• Depreciation = 12/20 = 60%; depreciated amount = 0.60 × $18,000 = $10,800
• ACV = $18,000 − $10,800 = $7,200

Under DP-1 (ACV form) the insured collects $7,200 (less deductible). Under DP-3 meeting the 80% coinsurance condition, the insured collects the full $18,000 replacement cost (less deductible), then is typically paid ACV first and the recoverable depreciation after repairs are completed.

Key Conditions and Common Endorsements

Conditions are the rules that make the contract work. Frequently tested DP conditions:

• Insurable Interest and Limit — the insurer never pays more than the insured's interest or the policy limit.
• Duties After Loss — prompt notice, protect property, submit a signed Proof of Loss within 60 days of the insurer's request, cooperate.
• Loss Payment — within 60 days after proof of loss and agreement.
• Pair or Set, Appraisal, Subrogation, Mortgage Clause (protects the lender even if the insured violates a condition).
• Cancellation/Nonrenewal, Liberalization (any broadening of the form during the term applies automatically at no charge), and Other Insurance (pro-rata) clauses.

The Proof of Loss deadline and Duties After Loss are the conditions most likely to defeat a claim: an insured who refuses to submit a signed, sworn proof of loss, ignores examination under oath, or fails to protect property from further damage can have an otherwise covered claim denied. The insurer in turn must pay within 60 days after receiving the proof of loss and reaching agreement on the amount, or after an appraisal award or court judgment fixes the amount.

Endorsements customize the DP form. Common ones: Broad Theft Coverage (DL 24 01 — adds theft, which is excluded in the base forms), Dwelling Under Construction, Automatic Increase in Insurance (inflation guard), Ordinance or Law, Personal Liability Supplement (DL 24 02) adding liability and medical payments, and Earthquake.

The Mortgage Clause and Other-Insurance Mechanics

The Standard Mortgage Clause is a tested favorite because it protects the lender as a separate contract. Even if the insured voids coverage (arson, fraud, increased hazard the insured concealed), the mortgagee is still paid to the extent of its interest, provided the lender pays any premium the insured failed to pay and notifies the insurer of known hazards. The insurer that pays a denied insured but an innocent mortgagee acquires the lender's rights via subrogation against the borrower.

When more than one policy covers the same dwelling, the Other Insurance condition makes each policy pay its pro-rata share — its limit divided by total limits, times the loss. A $100,000 loss split across a $200,000 and a $300,000 policy pays 2/5 ($40,000) and 3/5 ($60,000) respectively. Subrogation, appraisal (used to resolve disputes over the amount, not coverage), and the pair-or-set clause round out the conditions examiners most often quote.

The DP Broad-Form Peril List

DP-2 and the personal-property coverage of DP-3 insure against a broad named-peril list the exam expects you to recognize. Building on the basic fire/lightning/internal-explosion core, the broad form adds: windstorm and hail, explosion, riot and civil commotion, aircraft, vehicles, smoke, vandalism and malicious mischief, falling objects, weight of ice, snow, or sleet, accidental discharge or overflow of water or steam, sudden and accidental tearing apart/cracking/burning/bulging of a heating or water system, freezing of plumbing, and sudden and accidental damage from artificially generated electrical current.

The recurring qualifier is sudden and accidental — gradual leaks, seepage, and wear are excluded.

Vacancy and the Suspension of Perils

A frequently tested condition: when a dwelling is vacant beyond 60 consecutive days, the policy suspends coverage for vandalism, glass breakage, water damage, theft, and sometimes others, and reduces any otherwise-payable loss by a percentage. Vacant (no occupants and no contents) differs from unoccupied (furnished but nobody home) — only vacancy triggers the suspension. A landlord whose tenant moved out two months ago and a vandalism loss follows is the textbook fact pattern.

Key Dwelling Endorsements

• Automatic Increase in Insurance — raises Coverage A periodically to keep pace with inflation.
• Dwelling Under Construction — adjusts the limit to the completed value as the structure rises.
• Broad Theft / Limited Theft — adds the theft peril otherwise absent.
• Ordinance or Law — pays the extra cost to rebuild to current code (otherwise excluded).
• Earthquake and Water Back-Up of Sewers/Drains — buy back commonly excluded perils.

Coinsurance and Recovery on DP Forms

DP-2/DP-3 settle building losses at replacement cost if the insured carries at least 80% of replacement value; below that, recovery is the larger of ACV or the coinsurance-formula amount. DP-1 always settles at ACV. When a stem gives a replacement cost, an 80% requirement, a carried limit, and a partial loss, apply (carried ÷ required) × loss − deductible, then cap at the limit — identical mechanics to commercial coinsurance.
