Commercial Package Components and Covered Property

Commercial property insurance provides the financial bedrock for commercial enterprises facing catastrophic physical damage to their physical plant, inventory, and equipment. In California and throughout the United States, commercial property risks are predominantly underwritten using the standardized portfolio developed by the Insurance Services Office (ISO). Understanding the modular architecture of the Commercial Package Policy (CPP) and the specific mechanics of the core Building and Personal Property Coverage Form (CP 00 10) is a primary competency tested on the California Claims Adjuster licensing examination.

ISO Commercial Property Program Architecture

A commercial property policy can be issued as a standalone monoline policy or integrated into a Commercial Package Policy (CPP) combining property, commercial general liability, commercial auto, and inland marine coverages. A standard ISO commercial property program uses these components:

  1. Commercial Property Declarations: Identifies the named insured, described premises, policy period, mortgageholders, coverage limits, coinsurance percentages, deductibles, and applicable causes of loss forms.
  2. Common Policy Conditions (IL 00 17): Mandates administrative rules governing cancellation, changes, inspection and audit rights, assignment of the policy, and premium payment obligations.
  3. Commercial Property Conditions (CP 00 90): Governs property-specific rules including concealment or fraud, control of property, legal action against the insurer, other insurance, policy territory, and transfer of recovery rights (subrogation).
  4. Coverage Forms and Causes of Loss Forms: Establishes what property is insured (e.g., CP 00 10) and which perils trigger coverage (e.g., CP 10 10, CP 10 20, or CP 10 30).

Three Categories of Covered Property: CP 00 10

The ISO Building and Personal Property Coverage Form (CP 00 10) divides insurable physical assets into three distinct categories. Coverage applies only to those categories for which a specific limit of insurance is shown on the declarations page.

1. Building

Building coverage insures the building or structure described in the declarations, including:

  • Completed Additions: Structural extensions already completed and annexed to the primary building.
  • Fixtures: Permanent attachments to the structure, including outdoor fixtures (e.g., building-mounted lighting, flagpoles, permanently installed signage attached to the building).
  • Permanently Installed Machinery and Equipment: Boilers, heating, ventilation, and air conditioning (HVAC) systems, electrical sub-stations, and built-in manufacturing machinery.
  • Personal Property Used to Maintain or Service the Building: Property owned by the insured used to maintain the premises, including fire-extinguishing equipment, outdoor furniture, floor coverings, and appliances used for refrigerating, ventilating, cooking, dishwashing, or laundering.
  • Additions Under Construction: Additions, alterations, and repairs under construction, including materials, equipment, and supplies located on or within 100 feet of the premises used for completing the work (provided no other insurance applies).

2. Your Business Personal Property

Your Business Personal Property coverage insures business personal property owned by the named insured and used in the business. The property must be located in or on the described building, or in the open (or in a vehicle) within 100 feet of the building or premises. This category encompasses seven major categories:

  • Furniture and Fixtures: Desks, chairs, shelving units, retail display cases, and lighting not permanently annexed to the real property.
  • Machinery and Equipment: Freestanding production machinery, warehouse forklifts, computers, diagnostic tools, and printing presses.
  • "Stock": Merchandise held in storage or for sale, raw materials, goods in-process, finished goods, and supplies used in packaging or shipping.
  • Other Personal Property Owned by the Insured: Any other personal property owned by the policyholder and utilized in commercial operations.
  • Labor, Materials, or Services Furnished: The insured's labor and materials invested in personal property owned by others, such as an automotive machine shop's labor invested in a customer's engine block.
  • Leased Personal Property: Leased property for which the named insured has a contractual legal obligation to insure.
  • Tenant's Improvements and Betterments: Fixtures, alterations, installations, or additions made to a leased building by a tenant at their own expense, which cannot be legally removed upon lease termination (e.g., custom flooring, drop ceilings, built-in display rooms).

3. Personal Property of Others

Personal Property of Others provides insurance for personal property owned by others that is in the care, custody, or control of the named insured, located in or on the described building or within 100 feet of the premises.

Important

This coverage is useful for bailees such as dry cleaners, commercial equipment repair shops, consignees, and warehouse operators. Payment for property of others is for the account of its owner under the form. Furthermore, The property grant applies regardless of whether the insured was legally liable for the loss, functioning as direct first-party property insurance for customer goods rather than liability insurance.


Property Not Covered

To prevent moral hazard, avoid duplicating specialty marine or casualty policies, and exclude uninsurable risks, the BPP specifies a detailed list of Property Not Covered. Adjusters must verify whether damaged property falls under these explicit exclusions:

Excluded Property CategoryStatutory / Underwriting Rationale
Money, Securities, Scrip, & StampsExcluded under property forms; requires commercial crime or fidelity coverage.
Accounts, Bills, Currency, Deeds, & Evidences of DebtIntangible financial instruments; lack physical intrinsic value and require specialized inland marine coverage.
Land, Water, Growing Crops, & LawnsReal estate land value, retention ponds, and crops are excluded from commercial structures; crop-hail and multiple-peril crop products have different functions.
Bridges, Roadways, Walks, Patios, & Paved SurfacesCivil infrastructure improvements are exposed to earth movement and maintenance wear; requires specialized inland marine endorsements.
Contraband & Illegal PropertyContraband and property in illegal trade or transportation are excluded under this form.
Vehicles Licensed for Highway UseApply the form’s vehicle restrictions and stated exceptions, including eligible stock. Business auto or other specialty coverage can address different exposures.
Watercraft and AircraftHigh-hazard transportation risks requiring dedicated ocean marine, hull, or aviation coverage forms.
AnimalsExcluded unless owned by others and boarded by the insured, or held for sale as "stock" inside the building (e.g., a commercial pet store).
Electronic DataComputer software, records, and databases are excluded except for the limited $2,500 Electronic Data additional coverage in the 2012 specimen.
Underground Pipes, Flues, or DrainsSubterranean utilities are excluded due to earth movement exposure and difficulty of physical inspection.
Retaining Walls Not Part of BuildingExcluded unless specifically scheduled or attached as part of the primary foundation.

Coverage Extensions

When a policy displays a coinsurance percentage of 80% or higher on the declarations page (or is written on a Value Reporting form), CP 00 10 10 12 provides the following Coverage Extensions, subject to their particular conditions. Many provide additional insurance, but temporary portable storage is within the BPP limit and some valuable-record reproduction costs are also within it:

  1. Newly Acquired or Constructed Property:
    • Buildings: Up to $250,000 for each new building being constructed on the described premises or newly acquired at other locations.
    • Business Personal Property: Up to $100,000 at qualifying newly acquired locations, and qualifying new business property at described premises.
    • Duration: Coverage terminates after 30 days, upon reporting the values to the insurer, or upon policy expiration, whichever occurs first.
  2. Personal Effects and Property of Others: Up to $2,500 at each described premises for eligible personal effects owned by the insured or specified associated persons (the personal-effects grant excludes theft), and personal property of others in the insured's care, custody, or control.
  3. Valuable Papers and Records (Other than Electronic Data): Up to $2,500 at each described premises to cover the cost of researching, replacing, or restoring lost information on physical papers, blueprints, or legal documents damaged by a covered peril.
  4. Property Off-Premises: Up to $10,000 for covered property while temporarily at a location the insured does not own, lease, or operate (e.g., a trade show, exhibition, or temporary storage facility). Qualifying leased storage acquired after policy inception is another permitted location. The extension excludes property in/on a vehicle and salespersons’ custody except at a fair, trade show or exhibition.
  5. Outdoor Property: Covers fences, radio and television antennas, satellite dishes, trees, shrubs, and plants. The maximum limit is $1,000 total, with a strict sub-limit of $250 for any one tree, shrub, or plant.

    Note

    The Outdoor Property extension is strictly limited to five specific named perils: fire, lightning, explosion, riot or civil commotion, and aircraft. Windstorm, hail, vehicular impact, and vandalism are completely excluded under this extension.

  6. Non-Owned Detached Trailers: Up to $5,000 for leased or borrowed commercial trailers used in the business and located on premises, provided the insured has a contractual obligation to insure them.

  1. Business Personal Property Temporarily in Portable Storage Units: The 2012 specimen provides a $10,000 maximum within the applicable BPP limit for qualifying units within 100 feet of the described premises. The 90-day storage/use conditions and cause-form limitations apply. This is not indefinite coverage for an off-site warehouse.

Valuation and ownership interests

The CP 00 10 10 12 starting measure is ACV, with specified exceptions and optional replacement-cost coverage. Sold but undelivered stock uses selling price less discounts and expenses that would otherwise be incurred. Ordinary unsold stock is not automatically valued at its retail asking price. Glass uses the specified safety-glazing replacement measure. The small-building-repair provision requires its coinsurance and cost conditions; it is not universal replacement cost for every property category.

Tenant improvements receive ACV if promptly repaired under the default provision. If not promptly repaired, the form uses original cost multiplied by days from loss to lease expiration, divided by days from installation to expiration; the stated renewal-option rule applies. It pays nothing for those improvements if others pay to repair or replace them. An optional replacement-cost provision can alter this analysis. Thus title, use interest and who funds restoration must be investigated separately.

For example, assume original improvements cost $40,000, the relevant installation-to-expiration period is 1,000 days, and 250 days remain at loss. If the default nonrepair provision applies, the proportional amount is $40,000 × 250 ÷ 1,000 = $10,000 before applicable limits/deductibles. This calculation would be inappropriate if the tenant promptly repaired under a different applicable valuation grant.
