9.5 Commercial Property Endorsements and the BOP

Key Takeaways

  • Ordinance or Law (CP 04 05) restores three coverages: loss to the undamaged portion, demolition cost, and increased cost of construction.
  • Earthquake (CP 10 40) and flood are never built into the causes-of-loss forms and must be added separately or written through the NFIP.
  • Equipment Breakdown covers boiler, machinery, and electrical-arcing losses the causes-of-loss forms exclude.
  • The Businessowners Policy (BOP) is a pre-packaged product for small to mid-sized risks that writes property on a Special, replacement-cost basis automatically.
  • BOP business income is automatic for 12 months with no coinsurance and no waiting period, and ineligible classes include auto dealers, bars, banks, and most manufacturers.

Why Endorsements Matter

The BPP and the causes-of-loss forms leave deliberate gaps; endorsements restore or broaden coverage for an added premium. Knowing which endorsement solves which exposure is a steady source of exam questions.

Ordinance or Law in Three Parts

Coverage A pays for the value of the undamaged portion that a code forces you to tear down; Coverage B pays demolition cost; Coverage C pays the increased cost of construction to rebuild to current code. The base forms exclude all three, so older buildings in code-heavy jurisdictions need CP 04 05.

Flood and Earthquake

Flood and earth movement are excluded by Basic, Broad, and Special alike. Flood is usually written through the National Flood Insurance Program (NFIP) or a private flood policy; earthquake is added by CP 10 40, which carries its own (often percentage) deductible.

Worked Example - Ordinance or Law

A 40-year-old store suffers $300,000 of fire damage. The city orders the remaining structure demolished and rebuilt to current code, adding $90,000 of code-upgrade cost and $40,000 to demolish the undamaged walls. The base policy pays the $300,000 direct loss; only the CP 04 05 endorsement pays the extra $130,000 of demolition and increased construction cost.

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, written on ISO form BP 00 03. Unlike the hand-built CPP, its coverages bundle generous automatic features with simplified, class-based rating.

BOP Property Section

FeatureBOP automatic provision
Building and BPPSpecial (open-peril) form
ValuationReplacement cost automatically
Business income and extra expense12 months, no coinsurance, actual loss sustained, no waiting period
Seasonal increaseBPP limit auto-increases up to 25 percent in peak season
Newly acquired buildingsLimited automatic coverage (commonly up to $250,000)

The 12-month, no-coinsurance, actual-loss-sustained business income is the BOP's signature advantage over the CPP's separate CP 00 30 with a coinsurance election.

BOP Liability Section

LimitTypical amount
Each occurrence$1,000,000
General aggregate$2,000,000
Products-completed operations aggregate$2,000,000
Medical payments$5,000 per person
Damage to premises rented to you$50,000 to $100,000

Defense costs are paid in addition to the limits, just as under the commercial general liability form. Medical payments are paid without regard to fault, which often heads off a larger liability suit, while the general aggregate caps total payouts in the policy year and the each-occurrence limit caps any single claim.

Built-In Coverages That Cost Extra on a CPP

Beyond the headline features, the BOP packs in smaller automatic coverages a CPP would charge for separately - limited money and securities, forgery or alteration, fire department service charge, pollutant cleanup, business income from dependent property, and small sublimits for fire-extinguisher recharge and electronic data. This bundling is why a BOP often costs less than the sum of equivalent monoline coverages while still delivering broad protection, the core value proposition for an owner who employs no risk manager.

How a BOP Is Rated

BOP rating is class-rated rather than judgment-rated: the insurer slots the risk into a published class such as an office, restaurant, or apartment, applies a rate per $1,000 of property value and per square foot or unit, and adds liability by class and limit. Because rating is simplified, BOPs are quick to quote and issue, the trade-off being rigid eligibility. A risk that outgrows the size or revenue limits, or shifts to an ineligible class such as a retailer that begins manufacturing, must move to a CPP.

Eligibility

Eligibility is class- and size-driven: apartment, office, mercantile (retail), processing and service, and limited contractor or wholesale risks within stated building-size and revenue limits.

Common Traps

  • BOP building coverage is Special and replacement cost automatically - do not confuse it with the BPP's ACV default.
  • Auto dealers, bars, and manufacturers are ineligible; a restaurant with limited alcohol sales is generally eligible.
  • Ordinance or Law has three parts; only CP 04 05 restores demolition and increased construction cost.
  • Flood and earthquake are never built in - flood goes to the NFIP, earthquake to CP 10 40.
