3.3 Dwelling Perils, Conditions, and Endorsements

Exclusions — Even on Open Perils

The DP-3 is open-perils, but examiners love to test that open perils still has exclusions. The standard dwelling exclusions are:

• Ordinance or law — added cost to rebuild to current code (rebuilt by endorsement)
• Earth movement — earthquake, landslide, sinkhole (earthquake endorsement available)
• Water damage — flood, surface water, sewer/drain backup, underground water
• Power failure originating off the residence premises
• Neglect to save and preserve property at and after a loss
• War, nuclear hazard, and intentional loss by an insured
• Governmental action (seizure or destruction by order)

The DP-3 adds open-perils-specific carve-outs: wear and tear, deterioration, mechanical/electrical breakdown, settling/cracking, smog/rust, pollutants, and damage from insects, birds, rodents, or domestic animals. Mold is largely excluded with a narrow exception when it results from a covered water loss.

Many of these exclusions exist to keep insurance from paying for maintenance. Wear and tear, gradual deterioration, and settling are predictable owner expenses, not fortuitous accidents, so they are excluded on every form. Earth movement and flood are excluded because they are catastrophic, geographically concentrated, and would make coverage unaffordable if bundled into a standard dwelling rate. The fix is targeted: an earthquake endorsement for earth movement, a separate NFIP or private flood policy for flood. Neither is rebuilt by simply moving up to the DP-3.

Key Policy Conditions

Conditions tell you how the contract is administered after a loss:

The mortgage clause is heavily tested: a lender can still collect when the insured cannot, provided the lender meets its own duties of premium payment, proof of loss, and notice.

The appraisal condition is another favorite. Appraisal resolves disputes over the dollar amount of a loss, not whether the loss is covered. Each party hires an appraiser, the two appraisers select an umpire, and an agreement by any two of the three sets the amount. Coverage disputes are settled by the courts, not appraisal — choosing appraisal as the remedy for a coverage denial is a classic wrong answer. The duties-after-loss condition similarly protects the insurer: failure to give prompt notice, protect the property, or file a sworn proof of loss within the stated period can reduce or void recovery.

ACV vs. Replacement Cost Math

Actual Cash Value = Replacement Cost − Depreciation. Suppose a roof costs $20,000 to replace, has a 25-year expected life, and is 15 years old. Depreciation is 15/25 = 60%.

• Depreciation amount: $20,000 × 0.60 = $12,000
• ACV settlement (DP-1): $20,000 − $12,000 = $8,000
• Replacement-cost settlement (DP-2/DP-3, coinsurance met): $20,000 less deductible

This $12,000 difference is exactly why the DP-1 is cheaper and why a landlord with an aging building may still buy a DP-3 for replacement-cost recovery.

Endorsements That Rebuild Coverage

Because the base DP is narrow, endorsements are common:

• Personal Liability Supplement — adds Coverage L (liability) and Coverage M (medical payments); the only way to get liability on a DP.
• Broad Theft Coverage Endorsement — adds on/off-premises theft for owner-occupants; Limited Theft is for tenant-occupied risks.
• Dwelling Under Construction — adjusts the limit to reflect rising value as the structure is built; premium is based on the average amount during construction.
• Automatic Increase in Insurance — periodically raises Coverage A to keep pace with inflation.
• Ordinance or Law Coverage — buys back the excluded cost to rebuild to current building codes (often 10% of Coverage A).
• Earthquake Endorsement — adds earth-movement coverage with its own (often percentage) deductible.

The Big Exclusions and the Endorsements That Buy Them Back

Even open-peril DP-3 excludes a familiar list: ordinance or law, earth movement (earthquake), flood/water, war, nuclear hazard, neglect, intentional loss, and power failure originating off premises, plus wear and tear, mechanical breakdown, and vermin as maintenance items. The exam expects you to know which endorsement restores each gap:

Exam alert: The base dwelling policy has no liability and DP-1/DP-2 exclude theft unless added. Landlords commonly add Fair Rental Value protection and a liability endorsement to round out the rental exposure.
