Coinsurance Penalty on a Partial Strip-Center Fire
An LLC owns a 22,000-square-foot retail strip center. The building's replacement cost is $2,400,000. The policy has a $1,500,000 building limit, an 80% coinsurance clause, a $25,000 deductible, replacement-cost settlement, and no agreed value. A fire in one unit causes $400,000 in replacement-cost damage, $280,000 actual cash value, and $30,000 in debris-removal expense. The policy also provides 10% ordinance-or-law coverage and a $50,000 debris-removal sublimit. The insured has no other property insurance and has not made any prior claims. The insurer's adjuster says the claim is "underinsured" and applies the coinsurance formula. The owner wants to know whether to accept a $250,000 advance and rebuild, or to challenge the adjustment. The lease requires the owner to restore the shell within 180 days.
1. Compute the coinsurance penalty and the amount payable before any ordinance-or-law costs.
Read the worked answer
Required insurance = 80% × $2,400,000 = $1,920,000. Insurance carried = $1,500,000. The coinsurance ratio is $1,500,000 ÷ $1,920,000 = 0.78125, so the insured is a coinsurer for roughly 21.875% of the loss.
If the policy applies coinsurance to the entire covered loss, add the building damage and debris removal: $400,000 + $30,000 = $430,000. The debris amount is within the $50,000 sublimit. Payment before deductible = $430,000 × 0.78125 = $335,937.50. Subtract the $25,000 deductible: $310,937.50.
If the form applies coinsurance only to the building loss and treats debris removal as additional coverage, the math is ($400,000 × 0.78125) + $30,000 − $25,000 = $317,500. The adjuster must read the coinsurance and debris-removal clauses to determine which result governs. The $280,000 ACV figure matters only if the insured cannot or does not rebuild; it does not change the coinsurance ratio.
2. The building department now requires $90,000 of code upgrades to the damaged unit. How does the 10% ordinance-or-law coverage apply, and does it change the coinsurance result?
Read the worked answer
Ordinance-or-law coverage is limited to 10% of the $1,500,000 building limit, or $150,000. The $90,000 requirement is therefore within the sublimit. Under most commercial forms, ordinance-or-law coverage is additional coverage; whether it is itself subject to coinsurance depends on the wording. If it is not subject to coinsurance, add $90,000 to the payable amount: $310,937.50 + $90,000 = $400,937.50 (or $407,500 under the alternative calculation).
If the form includes ordinance-or-law within the coinsurance calculation, then the $90,000 must be added to the loss before applying the ratio: $430,000 + $90,000 = $520,000 × 0.78125 = $406,250, less the $25,000 deductible = $381,250. That is a material difference, so the adjuster should quote the policy language in the demand.
Also check whether the code upgrade triggers coverage for the undamaged portion of the building. Here the requirement is limited to the damaged unit, so the undamaged-portion coverage likely does not apply.
3. Should the owner accept the $250,000 advance and rebuild, and what should the adjuster recommend about the limit going forward?
Read the worked answer
The coinsurance penalty is contractual and generally not negotiable unless the insurer miscalculated the replacement cost or the limit was misrepresented. The adjuster should verify the $2,400,000 replacement-cost figure independently. If that figure is overstated, the required insurance drops and the penalty shrinks.
Accepting an advance is reasonable if the owner needs to start repairs, but the check should be accepted as a partial payment, not a release. The owner should not sign a proof of loss or settlement agreement that waives the right to contest the coinsurance calculation. Keep every receipt and contract because replacement-cost holdback will be released only after the work is completed.
Going forward, the limit should be at least $1,920,000, or the owner should buy agreed-value coverage. The premium savings from the $1,500,000 limit were illusory because the owner now bears nearly 22% of every loss. If the owner has other buildings, blanket coverage may reduce the chance of a repeat penalty.
