Homeowners Conditions and Duties After Loss

Key Takeaways

  • Section I conditions govern the property claim: duties after loss, the loss settlement (replacement cost vs. ACV) clause, appraisal, the suit-against-us deadline, and subrogation.
  • Replacement cost on the dwelling requires the insured to carry at least 80% of full replacement cost; falling short triggers a coinsurance-style penalty paid on a proportional formula.
  • Personal property is settled at actual cash value (ACV) by default; HO 04 90 / built-in replacement cost provisions can upgrade Coverage C settlement.
  • Duties after loss include prompt notice, protecting property from further damage, preparing an inventory, and submitting a signed proof of loss, usually within 60 days of the insurer's request.
  • Appraisal resolves disputes over the AMOUNT of loss, not over whether coverage applies; coverage disputes go to court under the suit-against-us condition.

Conditions: The Rules of the Game

The Conditions sections of the ISO HO 00 03 spell out the obligations both parties accept once a loss occurs. Section I conditions govern property; Section II conditions govern liability. The exam concentrates on the Section I conditions, because they drive how much the insured actually collects.

Duties After Loss (Section I)

After a covered property loss, the named insured must:

  1. Give prompt notice to the insurer or its agent.
  2. Protect the property from further damage and make reasonable temporary repairs (repair costs are reimbursable).
  3. Cooperate with the investigation and, if asked, submit to a recorded statement or examination under oath.
  4. Prepare an inventory of damaged personal property with quantities, descriptions, and amounts.
  5. Submit a signed, sworn proof of loss within 60 days of the insurer's request.

Failure to perform these duties can void or reduce the claim. The proof-of-loss deadline is a frequent test item - memorize 60 days after the company's request, not 60 days after the loss.

Loss Settlement: Replacement Cost and the 80% Rule

The Loss Settlement condition is the most heavily tested clause in property insurance. Two valuation methods appear:

  • Actual Cash Value (ACV) = replacement cost minus depreciation.
  • Replacement Cost (RC) = the cost to repair or replace with like kind and quality, with no deduction for depreciation.

The building (Coverage A - Dwelling and Coverage B - Other Structures) is settled at replacement cost, provided the insured carries insurance equal to at least 80% of the full replacement cost of the dwelling at the time of loss. This 80% requirement functions like a coinsurance clause.

The Coinsurance / Replacement-Cost Penalty Formula

If the insured carries less than 80%, the recovery on a partial loss is the greater of (a) the ACV of the damaged part, or (b) the amount produced by this formula:

Payment = (Limit Carried / 80% of Replacement Cost) x Loss - Deductible

Use this disciplined order on the exam:

  1. Find the required amount: 80% x full replacement cost.
  2. Form the ratio: limit carried / required amount.
  3. Multiply the ratio by the loss.
  4. Subtract the deductible.
  5. Compare to ACV; pay the larger; never exceed the policy limit.

Worked Coinsurance Example

A dwelling has a full replacement cost of $400,000. The insured carries Coverage A of $280,000 with a $1,000 deductible. A windstorm causes a $100,000 partial loss (ACV of the damaged portion is $70,000).

StepCalculationResult
Required (80%)0.80 x $400,000$320,000
Ratio$280,000 / $320,0000.875
RC formula0.875 x $100,000 - $1,000$86,500
ACV alternative$70,000 - $1,000$69,000
Insurer paysgreater of the two$86,500

Because the insured was underinsured (carried 70% of value, not 80%), it absorbs part of the loss: the $13,500 shortfall plus the deductible. Had the insured carried at least $320,000, the full $100,000 (less the $1,000 deductible) would be paid as replacement cost.

Personal Property, Appraisal, Suit, and Subrogation

  • Coverage C - Personal Property is settled at ACV by default; a built-in or endorsed replacement-cost provision (e.g., HO 04 90) upgrades contents settlement.
  • Appraisal - if the parties disagree on the amount of loss, either may demand it: each picks an appraiser, the two pick an umpire, and agreement by any two binds. It resolves value, never coverage.

Two final conditions close out Section I:

  • Suit Against Us - the insured cannot sue the insurer unless it complied with policy terms and the action is brought within two years (state-amended in many jurisdictions) after the loss.
  • Subrogation - after paying, the insurer steps into the insured's rights to recover from the at-fault party; the insured must not impair that right.
Test Your Knowledge

A home has a $500,000 replacement cost. The owner insures Coverage A for $300,000. A partial fire loss is $80,000 (deductible $1,000). Applying the replacement-cost penalty formula, the insurer pays approximately:

A
B
C
D
Test Your Knowledge

The insured and insurer agree the roof is a covered loss but disagree on the dollar amount of damage. The correct condition to invoke is:

A
B
C
D

The Insured's Duties After Loss - A Checklist the Exam Tests

Failing the duties after loss can reduce or void an otherwise valid claim, so the exam treats them as a memorizable list. After a covered loss the insured must:

  • Give prompt notice to the insurer or its agent (and notify police for theft).
  • Protect the property from further damage and make reasonable temporary repairs (keeping records).
  • Prepare an inventory of damaged personal property with quantities and values.
  • Cooperate in the investigation, exhibit the damaged property, and submit to examination under oath.
  • File a signed, sworn proof of loss within the time the policy states (commonly 60 days on request).
ConditionEffect on a dispute
AppraisalEither party may demand it to resolve a value dispute (each picks an appraiser; the two pick an umpire)
Suit against usInsured must sue within a stated period (often 2 years) and only after meeting all duties
SubrogationInsurer steps into the insured's recovery rights against a negligent third party

Exam Trap: Appraisal resolves disagreements over the amount of loss, not over whether coverage applies; a coverage denial is a legal question for the courts, not the appraisal panel.

Quick Recall - Conditions That Resolve Disputes

Two conditions decide how a value disagreement is settled, and the exam tests the difference:

  • Appraisal resolves disputes about the amount of loss: each side names an appraiser, the two select an umpire, and any two of the three agree on the value.
  • Suit against us bars a lawsuit until the insured has met all policy duties and is filed within the policy's stated period (often two years).
  • Subrogation transfers the insured's recovery rights to the insurer after payment.

Appraisal never decides whether coverage applies - that legal question is reserved for the courts.
