3.3 Dwelling Perils, Conditions, and Endorsements

Standard Exclusions

Even the open-perils DP-3 carves out major causes of loss. The dwelling exclusions track the broader property program:

• Flood (surface water, waves, tidal water, overflow) – covered only through the National Flood Insurance Program (NFIP) or a separate policy.
• Earthquake and earth movement – added back only by endorsement.
• War and nuclear hazard.
• Ordinance or law – the extra cost to rebuild to current building codes is excluded unless endorsed.
• Neglect – failure of the insured to use reasonable means to protect property at and after a loss.
• Wear and tear, deterioration, mechanical breakdown, rust, mold, and inherent vice – maintenance items, not insured perils.
• Power failure and intentional loss by the insured.

Exam tip: Flood and earthquake are the two exclusions tested most; both require separate coverage and are never picked up automatically by the DP-3 open-perils language.

How Exclusions Interact With Open Perils

A recurring point of confusion is how exclusions behave on the open-perils DP-3. Open perils does not mean everything is covered; it means everything is covered unless an exclusion or special limitation removes it. The exclusion list is therefore the true measure of a DP-3's breadth. When a flood, earthquake, or wear-and-tear loss occurs, the insurer points to the exclusion and the open-perils language provides no relief. This is also why a separately purchased flood or earthquake policy is not optional padding but the only route to those perils, regardless of which dwelling form is in force.

Key Policy Conditions

Conditions are the rules of the contract. The most heavily tested:

Vacancy and the Insured's Conduct

A dwelling left vacant changes the risk and the coverage. Standard rules:

• After the dwelling has been vacant for more than 60 consecutive days before a loss, vandalism and malicious mischief, glass breakage, water damage, and theft attempt losses are excluded or reduced.
• The insurer may also reduce a loss payment by a percentage when vacancy increased the hazard.

The insured's own behavior matters too. Intentional loss by an insured voids coverage for that insured, and concealment or fraud voids the policy. The appraisal clause does not resolve coverage disputes, only the dollar amount of a covered loss; coverage disputes go to the courts.

The Mortgage Clause

Most dwellings are financed, so the mortgage (mortgagee) clause is a frequent exam topic. Under it:

• A covered loss is paid to the insured and the mortgagee jointly, protecting the lender's security interest.
• The mortgagee's right to recover survives many acts of the insured that would otherwise void coverage (for example, the insured's fraud or increase of hazard), provided the mortgagee was unaware.
• The mortgagee must notify the insurer of a change in ownership or occupancy it becomes aware of, pay premium on demand if the insured fails to, and submit proof of loss if the insured does not.
• If the insurer pays the mortgagee for a loss it denies to the insured, the insurer gains the mortgagee's rights against the borrower (subrogation to the loan).

Common Endorsements

Endorsements modify the chosen base form. The most frequently sold:

• Personal Liability Supplement – adds Coverage L (personal liability) and Coverage M (medical payments) because no DP form includes liability.
• Automatic Increase in Insurance – raises Coverage A by a set percentage each year to keep pace with inflation.
• Ordinance or Law – pays the additional cost to rebuild to current codes, otherwise excluded.
• Broadened Theft / Theft Coverage – adds or expands theft, especially on owner-occupied dwellings (recall the DP-1 has none).
• Earthquake and Special Provisions – add the earthquake peril or adjust the form for state-specific requirements.

Exam tip: Whenever a question says coverage applies "by endorsement," the base form alone would not respond; liability and ordinance-or-law are the classic examples.

Duties After Loss in Practice

The Duties After Loss condition is a frequent exam target because failing it can defeat an otherwise valid claim. The insured must give prompt notice, take reasonable steps to protect the property from further damage (and keep records of repair costs), prepare an inventory of damaged personal property, cooperate in the investigation, and submit a signed, sworn proof of loss within the time the policy allows (commonly 60 days after the insurer requests it).

Worked example. An insured suffers a kitchen fire but waits four months to report it, by which time water and smoke residue have worsened the damage and the scene is altered. The insurer may reduce or deny the portion of the loss attributable to the delay under the neglect exclusion and the duties condition, even though fire itself is a covered peril.
