3.3 Dwelling Perils, Conditions, and Endorsements

Standard Exclusions

Dwelling forms exclude predictable, catastrophic, or maintenance-related causes of loss. Tested exclusions include:

• Ordinance or Law - the added cost to rebuild to current building codes (restorable by endorsement).
• Earth Movement - earthquake, landslide, sinkhole, mudflow (earthquake restorable by endorsement).
• Water Damage - flood, surface water, water below the ground, and sewer backup from outside (flood via the NFIP).
• Power Failure off premises, Neglect, War, Nuclear Hazard, and Intentional Loss.

On the open-peril DP-3, additional exclusions apply to Coverages A and B such as wear and tear, deterioration, mechanical breakdown, smog, rust, mold, settling, and animal/insect damage — the maintenance-type losses an 'all-risk' form would otherwise pick up.

Key Policy Conditions

The dwelling Conditions section governs how claims are paid and how parties behave.

• Other Insurance - if more than one policy covers a loss, each pays its pro rata share (its limit divided by total limits).
• Subrogation - the insurer succeeds to the insured's right to recover from a responsible third party.
• Suit Against Us - any legal action must be started within two years after the loss (state amendatory may change this).
• Loss Settlement - sets ACV vs. replacement cost and the 80% condition.
• Cancellation/Nonrenewal - insurer notice periods (commonly 10 days for nonpayment, longer for other reasons under state law).

The Mortgage Clause is heavily tested: the mortgagee's interest survives even when the insured's own act (such as arson by the owner) would void coverage for the insured.

Two more conditions deserve attention. The Pair or Set clause lets the insurer repair, replace, or pay the difference in value when only part of a set is damaged, rather than paying for the whole set. The Appraisal condition gives either party a way to resolve a dispute over the amount of loss (not coverage): each side names an appraiser, the two select an umpire, and an agreement by any two of the three is binding.

Finally, Duties After Loss require the insured to give prompt notice, protect the property from further damage, prepare an inventory, and submit a signed proof of loss within 60 days when requested — failure to cooperate can jeopardize the claim.

Vacancy and Core Endorsements

Vacancy rule: If the dwelling has been vacant for more than 60 consecutive days before a loss, the insurer will not pay for loss caused by vandalism, sprinkler leakage, glass breakage, water damage, theft, or attempted theft, and all other covered losses are reduced by 15%. This is a prime exam trap because partial recovery — not a flat denial — applies to the still-covered perils.

Commonly endorsed coverages:

Builders Risk and the Dwelling Under Construction Endorsement

A dwelling being built is insured with the Dwelling Under Construction provision (or a separate builders-risk policy). Coverage A is provisional, increasing as construction progresses, and coinsurance is measured against the completed value rather than the in-progress value. The exam tests that theft of building materials is typically excluded until the structure is enclosed and lockable, and that coverage usually ends when the dwelling is completed and occupied.

This pairs with the vacancy condition: once a building is vacant beyond 60 consecutive days, coverage for vandalism, glass breakage, water damage, theft, and sprinkler leakage is suspended, and other losses are paid at a 15% reduced amount. A dwelling under construction is treated as occupied for this purpose, which is why the construction endorsement matters.

Mortgagee Rights and Loss Settlement Conditions

Because most dwellings are financed, the mortgage clause (a standard, or "union," mortgage clause) gives the lender independent rights: the mortgagee is paid even if the insured's own claim is denied for an act the lender did not commit, receives notice of cancellation (typically 10 days), and may pay overdue premium to keep coverage in force. In exchange the insurer gains subrogation against the mortgagee's interest after paying it.

Other settlement conditions the exam tests include appraisal (either party may demand it to resolve a dispute over the amount of loss, not coverage), pro-rata other-insurance, the duty to file a sworn proof of loss within 60 days, and the insurer's option to repair or replace rather than pay cash. Knowing that appraisal settles value disputes — never coverage disputes — is a recurring distractor.

Core Endorsements Recap

Three endorsements appear on almost every dwelling exam. The Broad Theft Coverage endorsement adds theft to an owner-occupied dwelling (theft is not covered on the base DP forms). Automatic Increase in Insurance / inflation guard raises Coverage A by a stated percentage through the term to keep the insured above the 80% threshold. And the Dwelling Special Provisions edition adjusts the form to comply with a particular state's law. Recognizing which endorsement solves a stated gap — theft, inflation, or statutory conformity — is the skill the questions probe.
