9.5 Commercial Property Endorsements and the BOP

Key Takeaways

  • Ordinance or Law (CP 04 05) restores three excluded code-upgrade coverages: undamaged portion, demolition, and increased cost of construction.
  • Earthquake (CP 10 40) and flood are never in standard commercial property; earthquake needs an endorsement, flood a separate policy.
  • The BOP is a pre-packaged property + liability policy for small, low-hazard businesses, written open-peril at replacement cost.
  • The BOP has NO coinsurance clause and builds in business income up to 12 months of actual loss with no separate limit.
  • The BOP excludes workers compensation, commercial auto, and professional liability; those move an account toward a CPP.

Key Commercial Property Endorsements

Endorsements amend the BPP and causes of loss forms to add perils, restore excluded coverage, or change valuation. Knowing which endorsement solves which gap is heavily tested.

EndorsementFormWhat it does
Ordinance or LawCP 04 05Restores code-upgrade cost: loss to the undamaged portion, demolition, and increased cost of construction (three coverages, A/B/C)
Earthquake and Volcanic EruptionCP 10 40Adds the excluded earthquake/earth-movement peril; uses a percentage deductible
Spoilage CoverageCP 04 40Pays for perishable stock spoiled by breakdown or off-premises power interruption
Peak Season LimitCP 12 30Temporarily raises the BPP limit for seasonal inventory swings
Value Reporting FormCP 13 10Adjusts limits to reported values for fluctuating stock
Utility Services - Direct Damage / Time ElementCP 04 17 / CP 15 45Restores loss caused by off-premises utility failure

Ordinance or Law - the Three Coverages

Because building codes are excluded by all causes of loss forms, CP 04 05 restores three pieces: Coverage A pays the value of the undamaged portion of a building the code requires torn down; Coverage B pays demolition cost; Coverage C pays the increased cost of construction to rebuild to current code. Older buildings most need it.

The Businessowners Policy (BOP)

The Businessowners Policy (BOP) is a pre-packaged policy for small to mid-size, low-hazard businesses (offices, retail stores, apartments, restaurants, small contractors). Unlike the hand-assembled CPP, the BOP bundles property and liability into a single simplified form with built-in coverages and few options.

Why the BOP Is Exam-Friendly

The two most-tested BOP features are that it has no coinsurance clause (so no coinsurance penalty — property is written at replacement cost on an open-peril basis) and that business income is built in for up to 12 months of actual loss sustained with no dollar limit and no separate premium. Liability is included on a per-occurrence and aggregate basis comparable to a CGL.

What the BOP Does Not Cover

The standard BOP excludes workers compensation, commercial auto, professional liability, employment practices liability, and large/high-hazard risks. Those are written separately or push the account into a CPP. Ineligible classes typically include manufacturers above a size threshold, auto dealers, banks, bars/taverns with high liquor sales, and contractors with large payrolls.

Built-In BOP Coverages Worth Knowing

The ISO BOP bundles several coverages that the CPP would charge for separately: a small amount of money and securities, employee dishonesty, mechanical breakdown (equipment breakdown), the cost to research lost electronic data, fire department service charge, and a modest amount of outdoor signs. Property is written on a replacement cost basis, and because there is no coinsurance, a partial loss is simply paid up to the limit minus the deductible. Optional endorsements add hired/non-owned auto, employment practices liability, or higher liability limits, but anything high-hazard pushes the account out of the BOP and into a CPP.

Spotting an Endorsement Question

Exam stems describe a gap and ask which form fills it. A bakery losing refrigerated stock after a power outage points to Spoilage (CP 04 40); a ski shop whose inventory triples each winter points to Peak Season (CP 12 30); an older downtown building forced to rebuild to current code points to Ordinance or Law (CP 04 05); a region near a fault points to Earthquake (CP 10 40). Match the exposure word to the endorsement and the answer follows.

Common Traps

  • The BOP has no coinsurance — do not apply the coinsurance formula to a BOP loss.
  • BOP property is open-peril (Special) at replacement cost by default; the CPP defaults to ACV and lets the insured pick the causes of loss form.
  • Ordinance or Law (CP 04 05) is needed because all causes of loss forms exclude code-upgrade cost.
  • Earthquake and flood are still not in a BOP; flood needs a separate policy and earthquake needs an endorsement.
  • The BOP excludes WC, auto, and professional liability — those move the account toward a CPP.
