3.3 Dwelling Perils, Conditions, and Endorsements
Key Takeaways
- DP-2 adds broad named perils over DP-1's basic perils; DP-3 is open-peril on the building, so the insurer bears the burden of proving an exclusion to deny a claim.
- The DP coinsurance/loss-settlement provision requires insuring to at least 80% of replacement cost to collect replacement cost on partial losses; underinsurance triggers a penalty paid at ACV.
- Common exclusions mirror HO forms: ordinance or law, earth movement, water damage (flood/sewer backup), war, nuclear hazard, neglect, and intentional loss.
- Key endorsements include the Personal Liability Supplement (adds Coverage L and M), Automatic Increase in Insurance, Broad Theft/Limited Theft, and Dwelling Under Construction.
- Vandalism coverage is suspended after 60 consecutive days of vacancy, and the vacancy condition can reduce or void recovery on certain perils.
Perils Across the Forms
| Form | Peril Basis | Burden of Proof |
|---|---|---|
| DP-1 | Basic named: fire, lightning, internal explosion (EC and V&MM optional) | Insured proves a covered peril caused the loss |
| DP-2 | Broad named: adds falling objects, weight of ice/snow/sleet, accidental water discharge, freezing, artificially generated electrical current, building collapse | Insured proves a covered peril |
| DP-3 | Open peril on Coverage A and B; broad named on Coverage C | Insurer must prove an exclusion to deny |
The burden-of-proof shift on DP-3 is the single most important practical advantage of the open-peril form.
Coinsurance and Loss Settlement
The dwelling replacement-cost loss settlement condition (on DP-2 and DP-3) requires the insured to carry at least 80% of replacement cost at the time of loss to collect full replacement cost on a partial loss. If they carry less, the recovery is the greater of ACV or the amount produced by the coinsurance formula:
Payment = (Amount of insurance carried / Amount required) x Loss, less deductible
Worked Numeric: Coinsurance Penalty
A dwelling has a replacement cost of $400,000. The 80% requirement = $320,000. The owner carries only $240,000. A partial fire loss costs $100,000; the deductible is $1,000.
- Coinsurance ratio = $240,000 / $320,000 = 0.75
- 0.75 x $100,000 = $75,000
- Less the $1,000 deductible = $74,000 paid
The owner absorbs the remaining $26,000 of the loss as a penalty for underinsuring. Had they carried $320,000 or more, the policy would pay the full $100,000 minus the deductible ($99,000).
Exam trap: Coinsurance is tested on replacement cost, not market value or the limit purchased. Land value is never included in the replacement-cost calculation.
Standard Exclusions
The DP exclusions track the homeowners forms closely:
- Ordinance or law — cost to rebuild to current code (add the Ordinance or Law endorsement)
- Earth movement — earthquake, landslide, sinkhole collapse, mudflow
- Water damage — flood, surface water, sewer/drain backup, underground water
- Power failure off-premises, neglect, war, nuclear hazard
- Intentional loss by an insured
Exam trap: Flood is NEVER covered by a dwelling policy. Direct an exam scenario involving rising water to the National Flood Insurance Program (NFIP), not to a DP endorsement.
Key Conditions
- Vacancy — Vandalism and glass breakage are suspended after the dwelling is vacant more than 60 consecutive days.
- Pro rata liability / Other Insurance — the policy pays its share when other coverage applies.
- Subrogation, appraisal, and the suit-against-us clause all mirror standard property conditions.
Common Endorsements
| Endorsement | Effect |
|---|---|
| Personal Liability Supplement | Adds Coverage L (personal liability) and M (medical payments) the base form lacks |
| Automatic Increase in Insurance | Raises Coverage A by a stated percentage each year for inflation |
| Broad Theft / Limited Theft | Adds theft (Broad for owner-occupants; Limited for non-owner-occupied) |
| Dwelling Under Construction | Insures a home being built, with limits keyed to completed value |
| Ordinance or Law | Pays the extra cost to rebuild to current building code |
Replacement Cost Versus Actual Cash Value
The valuation method drives the dollars an exam question expects. Actual cash value (ACV) is replacement cost less depreciation, reflecting age and wear. Replacement cost pays to repair or replace with like kind and quality without deducting depreciation, subject to the 80% coinsurance requirement. DP-1 settles building losses at ACV; DP-2 and DP-3 settle at replacement cost when the 80% test is met. On contents, even DP-3 typically settles at ACV unless a replacement-cost-on-contents endorsement is added — a distinction candidates routinely miss.
How Coinsurance Penalties Actually Bite
Coinsurance penalizes only partial losses. On a total loss, the policy simply pays the limit (or the replacement cost up to the limit) regardless of the 80% test, because the insured cannot recover more than the limit anyway. The penalty therefore matters most on moderate fires and storm claims where the insured carried, say, 60% of replacement cost. Always identify whether the exam scenario is partial or total before applying the formula — a total-loss question that tempts you into a coinsurance calculation is a classic trap.
The Mortgagee (Loss Payee) Clause
Nearly every insured dwelling carries a mortgage, so the standard mortgage clause is a tested condition. It protects the lender's interest even if the insured's own claim is denied for an act the insured committed (such as arson or misrepresentation). The mortgagee receives separate notice of cancellation (commonly 10 days for nonpayment), may pay a premium the insured failed to pay, and is paid to the extent of its interest before the owner. This independent protection is why lenders require evidence of insurance before closing.
Other Insurance and Pro Rata Liability
When more than one policy covers the same loss, the dwelling form's pro rata clause shares the loss in proportion to each policy's limit. If a $100,000 loss is covered by a $300,000 policy and a $100,000 policy ($400,000 total), the first pays 75% ($75,000) and the second pays 25% ($25,000). This prevents the insured from collecting more than the loss and is the property-side analog to contribution by equal shares in liability coverage. Recognizing pro rata sharing is essential for multi-policy exam scenarios.
A dwelling with a replacement cost of $500,000 is insured for $300,000 on a DP-3 with an 80% coinsurance loss-settlement clause. A $120,000 partial loss occurs with a $1,000 deductible. What does the policy pay?
