Dwelling Restrictions and Added Options

In this lesson you will
  • Identify standard dwelling policy general exclusions and post-loss policy conditions.
  • Compare the eligibility rules, coverage scopes, and restrictions of the Broad Theft and Limited Theft endorsements.
  • Explain how the Automatic Increase in Insurance endorsement, Dwelling Under Construction endorsement, and Personal Liability Supplement modify standard dwelling policy coverage.

Standard Dwelling Policy Exclusions

Standard dwelling forms (DP-1, DP-2, and DP-3) share a core set of general exclusions. These exclusions apply across the policy to avoid covering catastrophic losses or events within the insured's direct control. Standard dwelling policies exclude losses caused by earth movement, including earthquake, landslide, and mudflow. Water damage from flood, surface water, waves, and sewer or drain backup is also excluded under standard dwelling forms.

Other standard exclusions address external utility failures, intentional harm, and governmental action. Off-premises power failure is excluded, though an ensuing loss caused by a covered peril, such as a fire resulting from a power surge, may be covered. Policies exclude losses from war, including insurrection, and nuclear hazards. Standard dwelling forms exclude a loss caused by an act committed by or at the direction of an insured with the intent to cause a loss; they also exclude loss resulting from an insured's failure to use reasonable means to save and preserve property at and after a loss.

Destruction or seizure of property by governmental authority is excluded, with a limited exception for action taken to prevent the spread of a covered fire. In addition, standard dwelling forms generally exclude the costs of enforcing building ordinances or laws, except to the extent the form provides limited additional coverage or an endorsement adds coverage.

For example, if heavy rains cause a nearby creek to overflow and flood a client's basement, the standard dwelling policy will not pay for the water damage. Similarly, if an insured homeowner intentionally sets fire to their own detached garage, the intentional loss exclusion prevents recovery.

Exam tip. Remember the off-premises power failure rule: the direct loss from the utility disruption is excluded, but if an ensuing covered peril develops, such as an accidental fire sparked when electricity returns, the policy covers the resulting fire damage.

Common mistakes

  • Assuming that standard dwelling policies cover personal liability automatically, forgetting that liability requires the Personal Liability Supplement or a standalone policy.
  • Believing that a landlord can buy the Broad Theft endorsement, when only an owner-occupant qualifies for Broad Theft.
  • Thinking that the Dwelling Under Construction endorsement covers the full completed limit from day one, rather than a percentage corresponding to work completed to date.
  • Assuming the initial notice of loss must always be submitted in writing, when the standard condition requires prompt notice without specifying it must initially be written.

Key points

  • Standard dwelling policies exclude catastrophic perils such as flood, earth movement, war, and nuclear hazards, as well as intentional losses, insured neglect, and off-premises power failure without an ensuing covered loss.
  • Post-loss conditions require the insured to provide prompt notice, protect property from further damage, keep repair records, and submit a sworn proof of loss within 60 days of the insurer's request.
  • Disagreements over loss amounts are resolved through the appraisal condition using two appraisers and an umpire, while other insurance pays on a proportionate share basis.
  • Unendorsed dwelling forms do not cover theft of personal property, though theft-related building damage may be covered; standard ISO Broad Theft covers eligible owner-occupants' personal property on and off premises worldwide, while Limited Theft provides on-premises coverage for eligible non-occupant owners, subject to its exclusions.
  • The Automatic Increase in Insurance endorsement raises building limits pro rata continuously throughout the term, while the Dwelling Under Construction endorsement covers an intended occupant's building based on the percentage completed to date.
  • The Personal Liability Supplement adds Coverage L for third-party legal liability and defense costs, along with Coverage M for no-fault medical payments to visitors within typically three years of an accident.
