9.5 Commercial Property Endorsements and the BOP

Key Takeaways

  • Key endorsements: Ordinance or Law (CP 04 05), Spoilage (CP 04 40), Earthquake (CP 10 40), Peak Season (CP 12 30), and Value Reporting (CP 13 10).
  • Ordinance or Law has three coverages: undamaged-portion loss (A), demolition cost (B), and increased cost of construction (C).
  • The BOP is a pre-packaged property-plus-liability policy for eligible small and mid-sized businesses, unlike the hand-assembled CPP.
  • BOP defaults are Special open-peril, replacement cost, and no coinsurance; business income runs 12 months with no waiting period.
  • Auto dealers, bars, most manufacturers, banks, and large or tall buildings are ineligible for the BOP.

Why Endorsements Matter

The base BPP and Causes of Loss forms leave deliberate gaps that endorsements close. Knowing which endorsement solves which exposure is a steady source of exam points.

EndorsementFormWhat it does
Ordinance or LawCP 04 05Pays to demolish undamaged portions and rebuild to current code (Coverage A loss of value, B demolition, C increased cost of construction)
SpoilageCP 04 40Covers perishable stock spoiled by power outage or equipment breakdown
EarthquakeCP 10 40Buys back the earth-movement exclusion
Peak SeasonCP 12 30Temporarily increases business personal property limits for seasonal inventory swings
Value ReportingCP 13 10Adjusts premium to fluctuating inventory values via periodic reports
Building Ordinance - ICCCP 04 09Coordinates with the BPP's increased cost of construction additional coverage

Ordinance or Law - The Three Coverages

Ordinance or Law (CP 04 05) is the most-tested endorsement because the base forms exclude code-upgrade costs. It has three parts:

  1. Coverage A - Loss to the undamaged portion of a building that an ordinance requires to be demolished (included in the building limit).
  2. Coverage B - The cost to demolish the undamaged portion and clear the site (a separate limit).
  3. Coverage C - The increased cost of construction to rebuild to current code (a separate limit).

Worked scenario: a fire destroys 60 percent of an older building, and code requires the remaining 40 percent be torn down because the damage exceeds 50 percent. Without CP 04 05, the BPP pays only for the burned 60 percent. With it, Coverage A pays the value of the undamaged 40 percent, Coverage B pays to demolish it, and Coverage C pays the extra cost of code-compliant reconstruction.

The Businessowners Policy (BOP)

The Businessowners Policy (BOP) is a pre-packaged policy combining property, liability, and business income for small and mid-sized businesses. Unlike the hand-built CPP, the BOP bundles coverages with generous automatic features and simplified rating - the commercial cousin of the homeowners policy.

Eligibility

Eligibility turns on class of business and size. ISO's BOP program targets apartment buildings, offices, mercantile (retail), processing and service, and certain limited contractor and wholesale risks within stated limits.

FactorTypical limit
Building sizeGenerally up to ~35,000 sq ft (varies by class)
Annual salesOften capped (commonly $3M-$15M per class)
Number of storiesUsually 6 or fewer for office/apartment
ClassMust appear on the eligible-class list

How the BOP Differs From the CPP

The BOP's appeal is that coverages requiring separate forms or endorsements on a CPP are built in.

FeatureBOP automatic provisionCPP equivalent
Building / BPP perilsSpecial (open-peril)Must select CP 10 30
ValuationReplacement costACV default unless RC elected
Business income & extra expense12 months, no coinsurance, actual loss sustained, no waiting periodRequires CP 00 30 with coinsurance
Coinsurance on propertyNone80% default
Seasonal increaseAuto up to 25% in peak seasonNeeds CP 12 30
Newly acquired buildingsLimited automatic (commonly up to $250,000)Extension at 80%+ coinsurance

The 12-month, no-coinsurance, actual-loss-sustained business income with no waiting period is the BOP's signature advantage - on a CPP the same protection needs a separate CP 00 30 with a coinsurance percentage and a 72-hour wait.

Liability Under the BOP

The BOP includes business liability and medical payments comparable to a CGL occurrence form, with typical per-occurrence limits such as $300,000, $500,000, or $1,000,000 and medical payments commonly $5,000 to $10,000 per person. Because liability is bundled, a small retailer gets coordinated property and liability under one product rather than assembling a CPP.

Common Traps

  • The BOP is pre-packaged; the CPP is hand-assembled. A stem describing a modular policy with separate coinsurance is a CPP.
  • BOP property is Special form and replacement cost by default, with no coinsurance - the opposite of the BPP's ACV/80-percent defaults.
  • BOP business income runs 12 months with no waiting period; the CPP's CP 00 30 imposes the 72-hour wait.
  • Large buildings, auto risks, most manufacturers, bars, and banks are ineligible for the BOP.

Optional Endorsements on the BOP

The BOP can be tailored with its own endorsements rather than the CPP forms. Common additions include hired and non-owned auto liability (the BOP excludes owned autos), employment-related practices coverage, liquor liability for incidental sales, and utility services - time element. Because the base BOP is already broad, exam questions usually test what the BOP does not include by default: owned-auto liability, professional liability, workers compensation, and flood or earthquake all require separate policies or endorsements.

Worked Comparison - Same Risk, Two Structures

Consider a 10,000-square-foot retail store with $400,000 of building value, $200,000 of contents, and $300,000 of projected annual income. On a CPP, the agent selects CP 00 10 with the Special CP 10 30, picks 80 percent coinsurance, elects replacement cost, and adds CP 00 30 with a coinsurance percentage and the 72-hour wait. On a BOP, all of that is built in: Special open-peril, replacement cost, no property coinsurance, and 12-month actual-loss-sustained business income with no waiting period - usually at a lower combined premium for an eligible class.
