Ridgeline Hardware: Coinsurance Penalty, Civil Authority, and Code Upgrades
Ridgeline Hardware insures its building under a commercial property form with an 80% coinsurance clause, in the amount of $2,000,000. An appraisal establishes the replacement cost of the building at $4,000,000. A fire causes $800,000 in covered damage; the policy carries a $10,000 deductible. The same fire damages the neighboring restaurant, and the fire marshal bars access to the entire block for five days. Ridgeline's owner files a business income claim for those five days and also submits $15,000 to demolish the remaining undamaged wall, because current code requires demolition before reconstruction.
1. Calculate the building claim payment and quantify what Ridgeline absorbs.

Apply the coinsurance formula step by step - the deductible comes out of the loss before the ratio is applied:
- Should have carried: 80% x $4,000,000 = $3,200,000
- Ratio: did / should = $2,000,000 / $3,200,000 = 0.625
- Loss net of deductible: $800,000 - $10,000 = $790,000
- Payment: 0.625 x $790,000 = $493,750
Uninsured loss to Ridgeline:
- Deductible: $10,000
- Coinsurance shortfall: $790,000 - $493,750 = $296,250
- Total absorbed: $306,250
Note the direction of the mistake: buying $2,000,000 of insurance on a $4,000,000 building looks like "50% coverage," but the penalty is not 50% of the loss - it is 37.5%, because the benchmark is 80% of value, not 100%. That is why the insured is often surprised by the size of the check. The remedy would have been either $3,200,000 of limit or an agreed value / no-coinsurance arrangement.
2. How many days of the five-day business income claim are payable, and why?
Read the worked answer
The trigger here is the civil authority extension, not direct physical damage to Ridgeline's own property - access was prohibited by a government order because of damage to a neighboring premises.
Standard commercial property forms impose a 72-hour waiting period before civil authority business income coverage begins. Compute in hours, not in whole days:
- Closure: 5 days = 120 hours
- Waiting period: 72 hours = 3 days
- Payable: 2 days
Two further constraints the adjuster must check:
- The civil authority action must result from damage to property other than the insured's, within the required distance (commonly one mile).
- The coverage period is capped (often 4 consecutive weeks) and must fall within the policy period.
So the answer is not "five days" and it is not "zero because our building wasn't hit." It is the excess over the waiting period, capped and inside the time limit.
3. Is the $15,000 demolition of the undamaged wall covered?
Read the worked answer
No - not on the unendorsed form. The ordinance or law exclusion bars loss caused by enforcement of building codes, and the standard form distinguishes three distinct exposures:
| Exposure | What it covers | Covered here? |
|---|---|---|
| A. Undamaged portion of the building | Value of the part that must be torn down | No - excluded |
| B. Demolition cost | Cost to tear down that undamaged portion | No - the $15,000 |
| C. Increased cost of construction | Extra cost to rebuild to current code | No - excluded |
Debris removal coverage does not rescue this: the wall was not damaged by the fire, so removing it is a code-driven cost rather than debris from a covered loss.
The fix is an Ordinance or Law endorsement covering A, B, and C (limits are usually stated separately, often as a percentage of the building limit). Because the coinsurance clause is measured against the building limit, the endorsement limit also needs to be reviewed so it does not create a fresh shortfall. An owner renovating an older building should raise this before the fire, not after.
