7.3 Dwelling Exclusions, Conditions & Endorsements

Key Takeaways

  • Standard ISO General Exclusions—including Ordinance or Law, Earth Movement, Water Damage (flood/sewer backup), Off-Premises Power Failure, Neglect, War, and Nuclear Hazard—apply across all dwelling forms under the concurrent causation doctrine.
  • The Appraisal Clause provides a formal mechanism to resolve disputes over the amount of loss (not coverage): each party selects an appraiser, the appraisers select an umpire, and an agreement of any two sets the binding loss award.
  • North Carolina Standard Fire Policy provisions require lawsuits against the insurer to be initiated within 3 years after the date of loss, following full compliance with policy conditions.
  • Broad Theft Coverage (DP 04 72) is designed for owner-occupants and provides on- and off-premises theft protection with internal sublimits, whereas Limited Theft Coverage (DP 04 73) is designed for landlords and covers on-premises theft only, excluding tenant property.
  • The Personal Liability Supplement (DL 24 01) adds Coverage L ($100k base personal liability with defense costs outside limits) and Coverage M ($1,000 base medical payments to others on a no-fault basis within 3 years).

7.3 Dwelling Exclusions, Conditions & Endorsements

In property loss adjustment, navigating policy exclusions, fulfilling procedural conditions, and interpreting critical endorsements represent the technical core of the claims adjuster's role. Because ISO Dwelling forms are modular, claims adjusters must determine not only whether a direct loss occurred, but whether concurrent causation exclusions apply, whether statutory North Carolina conditions were met, and how attached endorsements alter coverage limits and liabilities.


1. General Exclusions in ISO Dwelling Property Policies

Standard ISO Dwelling forms contain nine General Exclusions that apply to all property coverages (Coverages A, B, C, and D/E). Under the Concurrent Causation Doctrine, if a loss results from a combination of covered and excluded perils (e.g., wind and flood), the exclusion applies to eliminate coverage for any damage directly or indirectly caused by the excluded peril, regardless of any other contributing cause or sequence of events.

Detailed Analysis of Critical Exclusions

  1. Ordinance or Law: Excludes loss or increased repair costs resulting from the enforcement of any ordinance, building code, or zoning law regulating the construction, repair, or demolition of a building. (Can be endorsed or covered up to 10% in modern forms).
  2. Earth Movement: Excludes earthquake, landslide, mudslide, mudflow, earth subsidence, sinkhole collapse, and earth contraction/expansion. Direct fire or explosion resulting from earth movement is covered.
  3. Water Damage (Crucial Exam Concept):
    • Flood & Surface Water: Excludes flood, surface water, waves, tidal water, tsunami, storm surge, and overflow of any body of water.
    • Sewer & Drain Backup: Excludes water or water-borne material backing up through sewers, drains, or discharging from sump pumps (requires Water Backup Endorsement DP 04 95).
    • Subsurface Hydrostatic Pressure: Excludes water below ground level exerting hydrostatic pressure on foundations, basement walls, floors, or paved surfaces.
  4. Power Failure Off-Premises: Excludes loss resulting from the failure of power or other utility services if the failure occurs away from the described location. If power failure causes a covered peril on-premises (e.g., power failure causes a fire), the resulting fire loss is covered.
  5. Neglect: Excludes loss caused by the insured's failure to use all reasonable means to save and preserve property at and after the time of loss, or when endangered by an insured peril.
  6. Governmental Action: Excludes destruction, confiscation, or seizure of property by order of governmental authority. Exception: Destruction ordered by public health or fire authorities to prevent the spread of a covered fire is covered.

2. Policy Conditions & Claims Settlement Provisions

ISO Dwelling policies contain statutory and contractual conditions that govern the legal rights and obligations of both the policyholder and the insurer during claims handling.

1. Insured's Duties After Loss

When a loss occurs, the insured must strictly satisfy several affirmative duties:

  1. Give prompt written notice to the insurer or authorized agent.
  2. Protect the property from further damage, make reasonable emergency repairs, and maintain accurate records of repair expenses.
  3. Prepare a detailed inventory of damaged personal property, showing quantities, descriptions, Actual Cash Values, and amounts of loss claimed, accompanied by bills and receipts.
  4. Exhibit the damaged property to the adjuster and submit to examinations under oath (EUO).
  5. Send to the insurer, within 60 days of the insurer's request, a signed, sworn Proof of Loss detailing the time, origin of loss, insurable interests, all encumbrances, and other insurance policies.

2. Loss Settlement & Pair and Set Clause

  • Loss Settlement: DP-1 settles all property at ACV. DP-2 and DP-3 settle Coverages A & B at Replacement Cost if the 80% coinsurance condition is met, and Coverage C at ACV. Under the two-step settlement rule, the insured collects ACV initially and has 180 days from the date of loss to notify the insurer of intent to repair and recover the withheld depreciation holdback.
  • Pair and Set Clause: In a loss to a pair or set, the insurer is not obligated to pay for the total loss of the entire set. The insurer may elect to:
    1. Repair or replace any part to restore the pair or set to its pre-loss value; or
    2. Pay the financial difference between the Actual Cash Value of the set before and after the loss.

3. The Appraisal Clause

When the insurer and insured agree that coverage exists but fail to agree on the dollar amount of the loss, either party may demand appraisal in writing:

  • Each party selects a competent, impartial appraiser within 20 days of the written demand.
  • The two appraisers select a competent, disinterested umpire (if they cannot agree on an umpire within 15 days, either party may request a judge of a court of record to appoint one).
  • The appraisers evaluate the loss independently. If they reach an agreed figure, that figure is binding. If they disagree, they submit their differences to the umpire.
  • A written agreement signed by any two of the three (Appraiser + Appraiser, or Appraiser + Umpire) sets the final binding loss award.
  • Each party pays its chosen appraiser and splits the umpire's fee and administrative appraisal expenses equally (50/50).

4. Other Insurance and Pro-Rata Liability

If other valid and collectible property insurance covers the same loss, dwelling policies settle on a pro-rata basis:

Insurer’s Share=(Policy LimitTotal Limits of All Applicable Policies)×Covered Loss\text{Insurer's Share} = \left( \frac{\text{Policy Limit}}{\text{Total Limits of All Applicable Policies}} \right) \times \text{Covered Loss}

5. North Carolina Statutory Conditions

  • Cancellation Notice Rules: Under North Carolina law, the insurer must give 10 days' written notice for non-payment of premium. For cancellation during the first 60 days of a new policy or for non-renewal, the insurer must provide at least 30 days' written notice.
  • Suit Against Us (Statute of Limitations): Under North Carolina General Statutes governing the Standard Fire Policy, no legal action can be brought against the insurer unless all policy provisions have been complied with and the action is started within 3 years after the date of loss.

3. Critical Dwelling Policy Endorsements

Because baseline dwelling forms provide minimal monoline property protection, ISO provides standard endorsements to customize coverage for landlords and homeowners.

└──────────────────────────┴──────────────────────────────────────────────────┘

1. Automatic Increase in Insurance (DP 04 11)

Also known as the Inflation Guard Endorsement, this endorsement automatically increases Coverage A and Coverage B limits on a daily pro-rata basis throughout the annual policy term by a specified percentage (e.g., 4%, 6%, or 8%). It prevents policyholders from falling below the 80% coinsurance threshold during inflationary building cycles.

2. Theft Coverage Endorsements: Broad vs. Limited Theft

Standard dwelling policies exclude the peril of theft. Insurers provide two distinct endorsements to address theft risk:

FeatureBroad Theft Coverage (DP 04 72)Limited Theft Coverage (DP 04 73)
Eligible InsuredsOwner-Occupants of the dwellingLandlords / Non-Owner Occupants
Geographic ScopeOn-Premises & Off-Premises WorldwideOn-Premises ONLY (Described location)
Tenant PropertyExcludedExcluded (Covers landlord's furnishings only)
Money & Bullion Limit$200$200
Securities & Manuscripts$1,500$1,500
Jewelry, Watches, Furs$1,500 (for loss by theft)$1,500
Firearms & Accessories$2,500$2,500
Silverware & Goldware$2,500$2,500

3. Dwelling Under Construction Endorsement (DP 17 08)

Attached when a residential building is being constructed. Key provisions include:

  • Coverage Limit: The Coverage A limit is written for the full expected completed value of the dwelling.
  • Premium Rating: Premium is charged at a discounted rate (typically 50% of the normal rate) to reflect the average value exposed during the construction lifecycle.
  • Settlement: Loss payments reflect the actual percentage of completion at the moment of loss.
  • Occupancy Requirement: The insured must notify the insurer within 30 days of dwelling completion or occupancy.

4. Personal Liability Supplement (DL 24 01)

Dwelling policies contain no liability protection in their base wording. The Personal Liability Supplement attaches comprehensive liability coverage:

  • Coverage L — Personal Liability: Base limit of $100,000 per occurrence. Covers third-party bodily injury (BI) and property damage (PD) caused by an occurrence for which the insured is legally liable. Legal defense costs are paid by the insurer outside and in addition to policy limits.
  • Coverage M — Medical Payments to Others: Base limit of $1,000 per person. Pays necessary medical, surgical, dental, ambulance, hospital, and funeral expenses incurred within 3 years of the accident date. This is no-fault coverage applying to guests and visitors injured on premises or injured off-premises due to the insured's activities. It strictly excludes the named insured and regular household residents.

4. Comprehensive Adjuster Case Study

Claims Scenario: A landlord in Raleigh, North Carolina owns a single-family rental dwelling insured concurrently under two separate DP-3 policies (Policy A with Insurer A: $300,000 Coverage A limit; Policy B with Insurer B: $100,000 Coverage A limit). Policy A also carries a Limited Theft Coverage Endorsement with a $5,000 limit and a $500 deductible, while Policy B does not carry theft coverage. Both policies carry standard $1,000 property deductibles.

Incidents and Claims Filed:

  1. Burglary Loss: Burglars break into the rental home while between tenants. They tear out and steal the landlord's newly installed central HVAC exterior condenser unit ($4,200 ACV / $5,000 RC), steal landlord maintenance power tools from the garage ($1,200 ACV), and cause $2,500 in physical structural damage to the exterior door and frame.
  2. Subsequent Fire Dispute: Two months later, a kitchen electrical fire causes severe damage. Insurer A scopes the fire repair at $60,000 RCN, while the insured's public adjuster submits an estimate of $90,000 RCN. The parties reach an impasse and demand formal appraisal.

Adjuster's Technical Claim Resolution:

Part 1 — Theft & Burglary Claim:

  • Physical Door Damage ($2,500): Covered under Coverage A of both DP-3 policies as open-peril physical damage.
    • Total Insurance in force = $$300,000 + $100,000 = $400,000$.
    • Insurer A share: $\frac{$300,000}{$400,000} = 75% \times $2,500 = $1,875$.
    • Insurer B share: $\frac{$100,000}{$400,000} = 25% \times $2,500 = $625$.
  • Stolen HVAC Condenser ($4,200 ACV): Under DP-3, theft of building fixtures from an unoccupied structure is covered under the Limited Theft endorsement on Policy A.
  • Stolen Tools ($1,200 ACV): Landlord tools on-premises covered under Policy A Limited Theft.
  • Total Theft on Policy A: $$4,200 + $1,200 = $5,400$ (capped at $5,000 endorsement limit).
  • Policy A pays $$5,000 - $500 \text{ deductible} = $4,500$.

Part 2 — Fire Appraisal Resolution:

  • Insurer A and the insured each select an appraiser. The appraisers select an impartial local building contractor as umpire.
  • Insurer A's appraiser assesses the fire loss at $65,000. Insured's appraiser assesses it at $85,000.
  • The umpire and Insurer A's appraiser agree on an award of $72,000. Because two of the three signed the award, the $72,000 figure is legally binding on all parties.
  • Pro-Rata Settlement Allocation:
    • Insurer A pays: $75% \times $72,000 = $54,000 - $1,000 \text{ deductible} = $53,000$.
    • Insurer B pays: $25% \times $72,000 = $18,000 - $1,000 \text{ deductible} = $17,000$.
    • Total net indemnification paid to insured for fire loss: $70,000.
