Coinsurance, Civil Authority, and Code Upgrade After a Supply-Line Failure
Northgate Bakery owns a 12,000-square-foot building insured on a commercial property policy with a building limit of $1,200,000, a business personal property limit of $400,000, business income coverage of $500,000 with a 72-hour waiting period and a 30-day extended period of indemnity, and an 80% coinsurance clause on a replacement cost basis. A water supply line inside the building bursts, flooding the bakery and undermining the adjacent public sidewalk. The city closes the street for nine days because of the sidewalk collapse, blocking customer access. Building repairs take six weeks and cost $600,000; equipment and inventory damage is $120,000, and the replacement cost of the personal property is confirmed at $600,000. The current code requires a fire-suppression upgrade that adds $150,000. A commissary kitchen is rented for $8,000 per week for seven weeks. The bakery's business income loss runs $60,000 per month, and a wholesale account worth $30,000 per month cancels permanently. Each coverage part has a $10,000 deductible.
1. Calculate the building and business personal property payments, showing the coinsurance arithmetic and each deductible.

Coinsurance is calculated coverage part by coverage part, using the limit purchased, the value that should have been insured, and the loss.
Building: the 80% requirement is 0.80 × $2,000,000 replacement cost = $1,600,000. The limit purchased is $1,200,000, so the insured carried $1,200,000 ÷ $1,600,000 = 75% of the requirement. The $600,000 loss is reduced to $600,000 × 0.75 = $450,000. Subtract the $10,000 deductible for a payment of $440,000. The $160,000 shortfall is the insured's coinsurance penalty.
Business personal property: the requirement is 0.80 × $600,000 = $480,000, and the limit is $400,000. That is 83.3% of the requirement, which satisfies the 80% clause, so no penalty applies. The $120,000 loss is paid in full less the $10,000 deductible, or $110,000.
The different results illustrate the point of coinsurance: the same insured was adequately insured on personal property but substantially underinsured on the building. The $10,000 deductible applies separately to each coverage part, so it should not be applied once to the combined loss.
2. How long does business income coverage run, and does the civil authority closure add a separate period?
Read the worked answer
The period of restoration begins 72 hours after the physical damage and ends when the building should be repaired and reopened with reasonable speed, not when the insured actually reopens. Here that is six weeks of repairs, so the base business income loss is 1.5 months × $60,000 = $90,000. If the policy includes a 30-day extended period of indemnity, add one month of income, $60,000, for a total of $150,000, subject to the $500,000 limit. Extra expense for the commissary kitchen is a separate coverage, generally not subject to coinsurance, and runs while reasonably necessary to avoid or minimize the shutdown: seven weeks × $8,000 = $56,000, subject to its own limit and deductible treatment.
The civil authority closure does not simply add nine days on top. Civil authority coverage requires that access to the insured's premises be prohibited because of damage to property other than the insured's by a covered cause, and it usually has a short fixed limit, often four weeks. Here the bakery's own building was damaged and unusable, so the period of restoration already covers the lost income. Paying both would duplicate the same loss. The civil authority coverage matters only for any additional period when the bakery is physically usable but access is still prohibited after repairs are complete; document the dates carefully.
The permanently cancelled wholesale account is not automatically covered. Lost income from a customer who will not return may be recoverable during the period of restoration and any extended period, but a permanent loss generally requires extended business income or similar coverage and proof that the account would have continued.
3. Is the $150,000 fire-suppression upgrade covered, and what endorsements should Northgate buy?
Read the worked answer
Ordinance or law is excluded under the unendorsed commercial property form. The policy responds to the direct physical loss, not to the cost of bringing the undamaged portions of the building into compliance with a current code adopted after construction. Without an ordinance or law endorsement, the $150,000 upgrade is the insured's cost, and it is significant relative to the $1,200,000 building limit.
An ordinance or law endorsement can address three separate exposures: the value of the undamaged portion of the building that must be demolished, the cost of demolition, and the increased cost of construction or repair to comply with code. Each has its own sublimit or treatment, and the insured must read them because the increased-cost sublimit is often much smaller than the building limit. For a bakery, the fire-suppression requirement is a predictable upgrade, so the sublimit should be set at a realistic number rather than a default.
Northgate should also correct the coinsurance problem at renewal by insuring the building to at least $1,600,000, or by choosing agreed value or a margin clause, and should confirm whether the business income limit and extended period match the actual six-week rebuild and customer-recovery timeline. The $500,000 limit is adequate for this loss but would be thin for a total loss affecting the holiday season.
