16.2 Commercial Property: Building & Personal Property Coverage Form
Key Takeaways Explain This Topic AI
The ISO Building and Personal Property Coverage Form (CP 00 10) segregates insurable property into three distinct categories: Building, Your Business Personal Property (YBPP), and Personal Property of Others (PPO), each requiring an explicit limit on the Declarations.
Property Not Covered encompasses items better insured under specialized forms (such as cash, securities, and autos licensed for highway use) or uninsurable real property hazards (such as land, water, underground pipes, and foundations below the lowest basement floor).
Built-in Additional Coverages provide specified amounts automatically (e.g., Debris Removal at 25% of loss plus $25,000, Preservation of Property for 30 days, and Pollutant Clean-up at $10,000), whereas Coverage Extensions apply only when the Declarations show a coinsurance percentage of 80% or more or a value reporting period symbol.
The three ISO Causes of Loss Forms provide ascending tiers of peril protection: Basic (CP 10 10; 11 named perils), Broad (CP 10 20; Basic plus falling objects, weight of snow/ice/sleet, water damage, and collapse), and Special (CP 10 30; open perils with the legal burden of proof placed on the insurer).
The coinsurance condition penalizes underinsurance at the time of loss using the formula [(Carried Limit / Should Limit) * Loss] - Deductible, which can be suspended entirely by electing the Agreed Value optional coverage.

Commercial Property: Building & Personal Property Coverage Form
Quick Answer: The ISO Building and Personal Property Coverage Form (BPP - CP 00 10) is the foundational commercial property policy form in the United States. It provides coverage across three distinct categories: Building , Your Business Personal Property (YBPP) , and Personal Property of Others (PPO) . Coverage applies to property located in or on the described building or within 100 feet of the described premises. To tailor coverage to specific loss exposures, the BPP pairs with one of three primary Causes of Loss forms: Basic (CP 10 10) , Broad (CP 10 20) , or Special (CP 10 30) . When policyholders fail to maintain property limits meeting the specified coinsurance percentage (typically 80% or 90%) relative to the property's replacement or actual cash value at the time of loss, insurers apply a pro-rata coinsurance penalty that reduces the claim payout.
Commercial Property Policy Architecture & The ISO Modular Framework
Commercial property insurance is structured using a modular policy design established by the Insurance Services Office (ISO). A complete Commercial Property Policy (CPP) or commercial package consists of several integrated components:
Common Policy Declarations: Specifies the named insured, policy period, mailing address, premium summary, and list of included coverage parts.
Common Policy Conditions (IL 00 17): Applies mandatory contractual terms across all coverage lines, including cancellation provisions, changes, examination of books and records, inspections and surveys, and transfer of rights (subrogation).
Commercial Property Declarations: Details the specific premises locations, description of buildings, limits of insurance per category, applicable deductibles, coinsurance percentages, and optional valuation conditions.
Commercial Property Conditions (CP 00 90): Establishes property-specific operational rules, such as concealment/misrepresentation/fraud, legal action against the insurer (typically within 2 years), liberalization, other insurance, policy period/territory, and no benefit to bailee.
Building and Personal Property Coverage Form (CP 00 10): Defines what property is covered, what property is not covered, additional coverages, coverage extensions, and loss settlement conditions.
Causes of Loss Form (CP 10 10, CP 10 20, or CP 10 30): Identifies the perils insured against, general exclusions, and anti-concurrent causation language.
Endorsements: Tailors terms, alters valuation rules, or modifies peril exclusions.
The Three Categories of Covered Property (CP 00 10)
To establish coverage under the BPP, a monetary limit of insurance must be designated on the Declarations page for that specific category. The BPP categorizes insurable tangible property into three distinct classes: ┌─────────────────────────────────────────────────────────────┐
- │ BPP (CP 00 10) COVERED PROPERTY CATEGORIES │
- └─────────────────────────────────────────────────────────────┘
- │ │
- ┌────────────────────┴───────────┐ │
- ▼ ▼ ▼
- ┌─────────────────┐ ┌─────────────────┐ ┌─────────────────┐

- │ maint. equip. │ │ 100-ft radius │ │ 100-ft radius │
- └─────────────────┘ └─────────────────┘ └─────────────────┘
- 1. Building Property
The "Building" designation covers more than just the exterior walls and roof. Under the CP 00 10, Building property includes:
The Described Structure: The building or structure described in the Declarations, including completed additions.
Permanently Installed Machinery and Equipment: Boilers, central heating and air conditioning systems, electrical switchgear, elevators, and built-in manufacturing apparatus.
Fixtures, Including Outdoor Fixtures: Built-in lighting, plumbing fixtures, awnings, and outdoor lighting mounted to the structure.
Personal Property Used to Maintain or Service the Building: Fire extinguishers, outdoor maintenance equipment (e.g., snow blowers, lawnmowers owned by the building owner), floor sweepers, and appliances used for refrigerating, ventilating, cooking, dishwashing, or laundering furnished by the landlord.
Additions Under Construction: Additions, alterations, and repairs to the building, including materials, equipment, and temporary structures on or within 100 feet of the described premises, provided no other insurance covers them.
2. Your Business Personal Property (YBPP)
YBPP protects the insured's movable commercial assets located in or on the described building , or in the open (or in a vehicle) within 100 feet of the building or premises. YBPP comprises seven distinct categories:
Furniture and Fixtures: Desks, chairs, filing cabinets, movable display cases, and shelving.
Machinery and Equipment: Non-permanently installed machinery, forklifts, specialized diagnostic tools, and production computers.
Stock: Merchandise held in storage or for sale, raw materials, goods in process, and finished goods, including supplies used in packaging or shipping.
All Other Personal Property Owned by the Insured and Used in the Business: Office supplies, uniforms, marketing materials, and reference libraries.
Labor, Materials, or Services Furnished on Personal Property of Others: The value of repair work, materials, and labor expended by the insured on customer goods (e.g., an auto repair shop or dry cleaner's invested labor on a customer's vehicle or garment).
Tenant's Improvements and Betterments (T&I / TIB): Fixtures, alterations, installations, or additions made to a rented building by a tenant at their own expense, which cannot legally be removed (e.g., custom flooring, built-in acoustic ceilings, specialized architectural storefronts). Coverage protects the tenant's use interest in these improvements.
Leased Personal Property: Personal property leased to the named insured for which the insured has a contractual responsibility to procure insurance (unless insured under Personal Property of Others).
3. Personal Property of Others (PPO)
PPO covers personal property owned by third parties that is in the care, custody, or control (CCC) of the named insured, situated in or on the described building or within 100 feet of the premises.
Indemnity Basis: Coverage is designed for bailment situations, such as dry cleaners, appliance repair shops, computer technicians, and warehousing operations.
Legal Liability Independent: Unlike liability policies, PPO under the BPP pays regardless of whether the insured was legally negligent for the physical damage. Payment is made for the account of the owner of the property.
Property Not Covered & Carve-Out Rationale
The BPP contains a rigorous list of "Property Not Covered." Insurers exclude these property types for distinct underwriting reasons: some are more appropriately covered under specialized policy forms (e.g., Crime, Commercial Auto, Inland Marine), some represent severe catastrophic exposures (e.g., land, growing crops), and others are subterranean assets not subject to standard above-ground property perils.
Excluded Property Category Underwriting / Rationale Alternative Insurance Solution
Accounts, Bills, Currency, Deeds, Evidence of Debt, Money, Notes, Securities Highly susceptible to theft, moral hazard, and untraceable disappearance. Commercial Crime Policy (e.g., CR 00 21 Inside the Premises: Theft of Money and Securities)
Animals Living creatures represent biological hazards, disease, and speculative valuation (unless owned as stock inside buildings or boarded). Animal Mortality Floater, Specialized Agricultural Inland Marine
Automobiles & Vehicles Licensed for Highway Use Designed for road travel, subject to highway collisions, moving tort liability, and state financial responsibility laws. Commercial Automobile Policy (Business Auto Coverage Form CA 00 01)
Bridges, Roadways, Walks, Patios, Paved Surfaces Highly durable flatwork; underground or outdoor exposures vulnerable to non-standard perils. Commercial Property Endorsement or Inland Marine Bridge & Tunnel Form
Contraband or Property in Illegal Trade Violates public policy; no lawful insurable interest can attach to illegal goods. Uninsurable under any legal contract
Excavations, Grading, Backfilling, Land, Water Immense catastrophic exposures (erosion, landslide); land cannot be physically destroyed by fire. Specialized Difference-in-Conditions (DIC) or Flood/Quake placement
Foundations Below Lowest Basement Floor / Underground Pipes & Flues Subterranean structures are largely immune to typical surface perils (fire, windstorm) and artificially inflate coinsurance values. Specific endorsement (CP 14 10) deleting the foundation exclusion
Pilings, Piers, Wharves, Docks, Retaining Walls Not Part of Building Waterfront exposures vulnerable to wave wash, tidal surge, and marine perils. Ocean Marine Hull/Piers Floaters, Commercial Inland Marine
Electronic Data Intangible asset subject to malware, corruption, and systemic deletion (covered up to $2,500 under Additional Coverages). Cyber Liability Policy / Electronic Data Processing (EDP) Inland Marine Floater
Additional Coverages vs. Coverage Extensions
The BPP provides ancillary coverages through two distinct mechanisms: Additional Coverages (built into the form and automatically available) and Coverage Extensions (which activate only if the policy Declarations show a coinsurance percentage of 80% or more or a value reporting period symbol). ┌────────────────────────────────────────────────────────┐

- └─────────────────────────┘ └────────────────────────┘ └──────────────────────────────────┘
- 1. Built-in Additional Coverages
These coverages are provided automatically without requiring an 80% coinsurance condition:
Debris Removal: Pays the cost to remove debris of covered property damaged by a covered peril. The standard limit is 25% of the total amount paid for the direct physical loss plus the deductible . If the debris removal expense exceeds this 25% allocation, or if the combined loss and debris removal exceeds the policy limit, an additional $25,000 is available per occurrence.
Preservation of Property: If the insured moves covered property to protect it from damage by an imminent covered peril, the BPP provides open-peril coverage for direct physical loss while being moved and for up to 30 days at the temporary storage location.
Fire Department Service Charge: Provides up to $1,000 (unless a higher limit is shown in the Declarations) for fire department response charges assumed by contract or required by local ordinance. This payment is in addition to policy limits and carries no deductible .
Pollutant Clean-Up and Removal: Covers expenses to extract pollutants from land or water at the described premises if the discharge is caused by a covered cause of loss occurring during the policy period. Provides up to $10,000 annual aggregate , and the loss must be reported to the insurer in writing within 180 days of the event.
Increased Cost of Construction: Applies only when the Replacement Cost valuation optional coverage is activated. It pays the increased cost to comply with the enforcement of building ordinances or laws regulating repair or construction following a covered physical loss. Provides up to the lesser of $10,000 or 5% of the building limit .
Electronic Data: Pays to replace or restore electronic data destroyed or corrupted by a covered cause of loss, with a standard limit of $2,500 annual aggregate .
2. Coverage Extensions
Coverage Extensions act as supplemental insurance amounts, payable in addition to the policy's stated limits. They apply only when the Declarations show a coinsurance percentage of 80% or greater or a value reporting period symbol:
Newly Acquired or Constructed Property:
Buildings: Up to $250,000 per building for new structures being built on the described premises or newly acquired buildings at other locations intended for similar use or warehouse operations.
Business Personal Property: Up to $100,000 per building at newly acquired locations or newly constructed buildings.
Coverage Window: Coverage ceases 30 days after acquisition/construction begins, when the insured reports values to the carrier, or upon policy expiration, whichever occurs first.
Personal Effects and Property of Others: Up to $2,500 per described premises for personal effects owned by the insured, officers, partners, or employees (excluding loss by theft), and personal property of others in the insured's care, custody, and control.
Valuable Papers and Records (Other Than Electronic Data): Up to $2,500 per premises for the cost to research, replace, or restore lost information on paper records damaged by a covered peril.
Property Off-Premises: Up to $10,000 for covered property temporarily located away from the premises (e.g., at a trade show, exhibition, or in storage at a leased location), excluding property in or on a vehicle or in the care of a salesperson.
Outdoor Property: Covers outdoor fences, radio/TV antennas, trees, shrubs, and plants, but only for losses caused by the perils of fire, lightning, explosion, riot, civil commotion, or aircraft . The maximum limit is $1,000 total , with a sublimit of $250 per tree, shrub, or plant (windstorm and vehicle damage are strictly excluded).
Non-Owned Detached Trailers: Up to $5,000 for trailers used in the business that the insured does not own, provided there is a contractual duty to insure them.
Business Personal Property Temporarily in Portable Storage Units: Up to $10,000 for property in portable storage units (e.g., PODS) located within 100 feet of the premises, for a maximum of 90 days .
Causes of Loss Forms: Basic vs. Broad vs. Special
The BPP coverage form contains no peril definitions within its own text. It must be attached to one of three Causes of Loss forms to determine which hazards are covered.
Feature Basic Form (CP 10 10) Broad Form (CP 10 20) Special Form (CP 10 30)
Peril Architecture Named Perils (11 perils) Named Perils (14 perils + Collapse) Open Perils (Covers direct physical loss unless excluded)
Burden of Proof Insured must prove peril caused loss Insured must prove peril caused loss Insurer must prove loss was caused by an excluded peril
- Fire & Lightning Included Included Included
- Explosion, Wind, Smoke Included Included Included
- Vandalism & Sprinkler Leakage Included Included Included
- Sinkhole Collapse & Volcanic Action Included Included Included
- Falling Objects Excluded Included (Roof exterior must be penetrated first) Included
- Weight of Snow, Ice, or Sleet Excluded Included Included
- Water Damage (Accidental Leakage) Excluded Included (Plumbing/HVAC discharge, not flood) Included
- Collapse Additional Coverage Excluded Included (Specified causes: decay, insect damage, weight) Included
- Theft of Personal Property Excluded Excluded Included (Subject to standard sublimits and exclusions)
- The Anti-Concurrent Causation Doctrine and Mandatory Exclusions
Under the Special Form (CP 10 30), coverage is presumed unless the insurer demonstrates that an exclusion applies. Furthermore, eight specific catastrophic exclusions are governed by the anti-concurrent causation (ACC) lead-in clause. This clause states that loss caused directly or indirectly by any of these eight perils is completely excluded , regardless of any other cause or event contributing concurrently or in any sequence to the loss:
Ordinance or Law: Enforcement of any municipal code or law regulating construction, repair, or demolition.
Earth Movement: Earthquake, landslide, mine subsidence, earth sinkage, or volcanic eruption (volcanic action is covered).
Governmental Action: Seizure or destruction of property by governmental authority (except destruction to prevent the spread of a fire).
Nuclear Hazard: Nuclear reaction, radiation, or radioactive contamination.
Utility Services (Off-Premises): Failure of power, communication, water, or other utility service occurring away from the described premises.
War and Military Action: Declared war, civil war, insurrection, or warlike action.
Water: Flood, surface water, waves, tidal water, tsunami, overflow of any body of water, spray from any of these, mudslide, sewer or drain backup, and subterranean water seepage.
Fungus, Wet Rot, Dry Rot, and Bacteria: Presence, growth, or spread of mold or rot (except as provided under limited $15,000 additional coverage).
Other exclusions not subject to anti-concurrent causation include wear and tear, rust, corrosion, continuous seepage of water over 14+ days, mechanical breakdown, dishonest acts of employees, and unexplained inventory shortage.
Valuation Conditions: ACV, Replacement Cost, and Agreed Value
How a covered loss is adjusted depends upon the valuation provisions selected in the Declarations:
1. Actual Cash Value (ACV) Standard
By default, the BPP settles losses on an Actual Cash Value (ACV) basis. ACV is traditionally defined in property-casualty jurisprudence as Replacement Cost minus physical depreciation (taking into account age, wear, tear, and obsolescence). Alternatively, some jurisdictions apply the Broad Evidence Rule , allowing adjusters and courts to evaluate any relevant factor affecting value (e.g., market value, neighborhood deterioration, economic obsolescence).
2. Replacement Cost (RC) Endorsement
If the Declarations activate the Replacement Cost optional coverage:
The insurer agrees to settle losses without deduction for physical depreciation, paying the cost to repair or replace damaged property with materials of like kind and quality.
Actual Repair Requirement: The policyholder must actually repair, rebuild, or replace the property within a reasonable timeframe. If the insured chooses not to rebuild, settlement defaults to ACV.
Underwriters' Safeguard: To prevent moral hazard, the insured can initially file an ACV claim and subsequently file for the replacement cost difference within 180 days of the loss once repairs are completed.
3. Agreed Value Optional Coverage
The Agreed Value provision is used when coinsurance compliance would be difficult to establish due to fluctuating values or unique structures. Under Agreed Value:
The insured and insurer agree upon the insurable value of the property prior to policy inception, substantiated by an audited Statement of Values.
The coinsurance clause is completely suspended for the agreed timeframe.
In the event of a total or partial loss, the insurer pays the full loss up to the agreed limit, provided the limit equals or exceeds the agreed value amount.
4. Inflation Guard and Peak Season Endorsements
Inflation Guard (optional coverage in the form): Automatically increases the building or personal property limit continuously throughout the policy period by an agreed annual percentage (e.g., 4%, 6%, or 8%) applied on a pro-rata daily basis, preventing underinsurance caused by rising construction costs.
Peak Season Limit of Insurance Endorsement: Automatically increases YBPP limits during specified peak operational months (e.g., a retailer increasing inventory coverage by $500,000 from October 1 to December 31) without requiring permanent limit increases or mid-term policy cancellations.
Coinsurance Formula & Numerical Penalty Calculations
The Coinsurance Condition encourages commercial policyholders to purchase adequate insurance relative to the actual value of their property. Underwriters offer discounted rates per $100 of coverage when an insured agrees to an 80%, 90%, or 100% coinsurance clause.
The Mathematical Coinsurance Formula Claim Payment = ( Amount of Insurance Carried Value of Property at Time of Loss × Coinsurance Percentage × Amount of Loss ) − Deductible \text{Claim Payment} = \left( \frac{\text{Amount of Insurance Carried}}{\text{Value of Property at Time of Loss} \times \text{Coinsurance Percentage}} \times \text{Amount of Loss} \right) - \text{Deductible} Claim Payment = ( Value of Property at Time of Loss × Coinsurance Percentage Amount of Insurance Carried × Amount of Loss ) − Deductible Payment = ( Did Should × Loss ) − Deductible \text{Payment} = \left( \frac{\text{Did}}{\text{Should}} \times \text{Loss} \right) - \text{Deductible} Payment = ( Should Did × Loss ) − Deductible
Note: The final payment can never exceed the stated policy limit of insurance, and the deductible is applied after the coinsurance penalty calculation.
- Worked Practical Scenarios: Coinsurance and Property Adjustments
- Scenario 1: Applying the Coinsurance Penalty
Building Profile: Industrial warehouse located in Cleveland, Ohio.
Actual Value at Time of Loss: $2,000,000 (Replacement Cost).
Coinsurance Requirement: 80%.
Required Limit ("Should"): 2,000,000 × 80% = $1,600,000.
Policy Limit Carried ("Did"): $1,200,000 (Underinsured).
Deductible: $10,000.
Loss Sustained: $400,000 physical fire damage.
Calculation Steps:
Calculate the Coinsurance Ratio: Carried Should = $ 1 , 200 , 000 $ 1 , 600 , 000 = 0.75 (or 75 % ) \frac{\text{Carried}}{\text{Should}} = \frac{\$1,200,000}{\$1,600,000} = 0.75 \text{ (or } 75\%\text{)} Should Carried = $1 , 600 , 000 $1 , 200 , 000 = 0.75 (or 75% )
Apply the ratio to the gross loss: $ 400 , 000 × 0.75 = $ 300 , 000 \$400,000 \times 0.75 = \$300,000 $400 , 000 × 0.75 = $300 , 000
Subtract the deductible: $ 300 , 000 − $ 10 , 000 = $ 290 , 000 \$300,000 - \$10,000 = \mathbf{\$290,000} $300 , 000 − $10 , 000 = $290 , 000
Result: The insurer pays $290,000 . The policyholder absorbs a $110,000 financial penalty ($100,000 coinsurance penalty + $10,000 deductible) due to failing to carry an adequate property limit.
Scenario 2: Debris Removal Additional Coverage Calculation
Loss Profile: Commercial retail strip center experiences severe fire damage.
Building Limit: $1,000,000.
Direct Physical Loss to Building: $900,000.
Debris Removal Expense: $260,000.
Deductible: $5,000.
Calculation Steps:
Pay the direct loss: $900,000 − $5,000 deductible = $895,000 .
Apply the 25% debris cap: 25% × ($895,000 paid + $5,000 deductible) = $225,000 . Debris removal is included within the building limit.
Apply the limit: Only $1,000,000 − $895,000 = $105,000 of the limit remains, so $105,000 of debris removal is paid within the limit (less than the $225,000 cap).
Additional $25,000: Because debris removal expense plus the direct loss payment exceeds the limit (and the expense also exceeds the 25% cap), the additional $25,000 of debris removal coverage applies.
Result: Total debris payment = $105,000 + $25,000 = $130,000 . Total paid = $895,000 + $130,000 = $1,025,000. The insured absorbs the remaining $130,000 of debris removal cost plus the $5,000 deductible.
Common Exam Traps & Strategic Pitfalls
Warning
Exam Trap 1: Coinsurance is Evaluated at Time of Loss, Not Inception A policyholder may purchase an insurance limit that perfectly satisfies an 80% coinsurance requirement on January 1. If rapid inflation or local construction cost surges increase the property's replacement cost by 25% by November, and a loss occurs on December 1, the coinsurance calculation is evaluated based on the property value at the exact time of the loss . The insured will incur a severe coinsurance penalty unless they attached an Inflation Guard endorsement or maintained an Agreed Value provision.
Caution
Exam Trap 2: Outdoor Property Peril Limitations Candidates frequently assume that because an insured selected the Special Form (CP 10 30), outdoor fences, trees, and shrubs are covered for windstorm or vehicle damage under the Coverage Extension. Under the BPP, the Outdoor Property extension strictly covers only six perils : fire, lightning, explosion, riot, civil commotion, and aircraft. A tornado or windstorm blowing down expensive decorative trees yields $0 under the BPP.
Note
Exam Trap 3: Tenant's Improvements and Betterments Ownership Improvements and betterments installed by a commercial tenant legally become the real property of the building landlord upon installation. However, under the BPP, the tenant can insure them under Your Business Personal Property (YBPP) because the tenant possesses an insurable use interest during the lease term.
