ACORD 140 Property Section: A Comprehensive Analysis for Brokers

ACORD 140 is the commercial property section of the ACORD commercial lines application suite. It functions as the property-specific data collection form used alongside the ACORD 125 (General Information page), which captures the insured's identity, contact information, and general business operations. ACORD 140 collects the building and contents data that carriers need to underwrite commercial property coverage - construction type, occupancy, protection class, coverage limits, valuation basis, coinsurance percentage, and deductibles. Errors on ACORD 140 are among the top causes of commercial property E&O claims because a wrong construction class or valuation basis mismatch can produce coverage that does not pay what the client expects.

Key Takeaways

• ACORD 140 is the commercial property application section, used with ACORD 125 (General Information) - not a standalone form and not a certificate of insurance.
• ACORD 140 differs from ACORD 24 in function: ACORD 24 is an evidence-of-insurance document; ACORD 140 is an underwriting application.
• The five ISO construction classes (Frame, Joisted Masonry, Non-Combustible, Masonry Non-Combustible, Fire Resistive) are the most consequential data points - misclassification can cause coverage disputes at loss.
• Valuation basis (replacement cost, ACV, or agreed value) determines how a claim is settled - selecting the wrong basis is a coverage error, not just a documentation error.
• Protection Class (PC 1 through PC 10) from ISO's Public Protection Classification program can shift commercial property premiums by 30% to 60% for the same building.
• Coinsurance percentage defaults to 80% in most property forms - selecting 80% without confirming the insured can meet the requirement at loss exposes the agency to E&O claims.
• Carriers including Travelers, Hartford, and Cincinnati frequently decline or request additional information on submissions with missing square footage, unknown occupancy class, or valuation basis inconsistent with the building age and condition.

What ACORD 140 Is - and What It Is Not

The acord-form ACORD 140 is a standardized application form developed by ACORD (Association for Cooperative Operations Research and Development) to collect property underwriting information for commercial lines submissions. It is part of the ACORD commercial lines application suite that typically includes:

• ACORD 125 - General Information (insured identity, operations, prior losses)
• ACORD 140 - Commercial Property Section (building data, coverage requirements)
• ACORD 130 - Commercial General Liability Section (if GL coverage is also being quoted)
• ACORD 137 - Commercial Property - Additional Locations (when multiple locations are involved)

ACORD 140 is an underwriting application. The carrier uses it to evaluate risk and determine whether to offer coverage and at what premium. It is not a policy, a binder, or a certificate. Specifically, it differs from:

ACORD 24 - The ACORD 24 is a Property Insurance Evidence form. It is issued after a policy is bound and provides evidence-of-insurance to a third party (typically a lender or lessor). ACORD 24 shows coverage that exists; ACORD 140 is the application to obtain coverage that does not yet exist. Confusing these forms - for example, providing an ACORD 24 to a carrier as a substitute for an ACORD 140 application - is a fundamental workflow error.

ACORD 25 - The ACORD 25 is a certificate-of-insurance for liability insurance. It is unrelated to commercial property applications.

Section-by-Section Breakdown of ACORD 140

Section 1: Location and Building Description

The first section captures the physical property. Required fields include:

• Street address (must match the carrier's address verification - PO Box insufficient)
• Building description: number of stories, year built, total area in square feet
• Number of units (for habitational)
• Current occupancy

Year built matters for underwriting. Buildings constructed before 1970 trigger underwriting scrutiny at most carriers because electrical wiring systems (knob-and-tube, aluminum wiring) and plumbing materials (galvanized pipe, lead pipe) present higher loss potential. Hartford's commercial property underwriting guidelines, for example, require a property condition report for buildings constructed before 1975 when replacement cost valuation is requested.

Section 2: Construction Type

ISO defines five construction types used across commercial property underwriting:

Construction class is the single most consequential classification on ACORD 140. A building classified as Frame (Class 1) versus Masonry Non-Combustible (Class 4) can differ by 40% to 80% in commercial property premium for an equivalent building value. More importantly, a misclassification discovered at loss can give the carrier grounds to contest coverage if the misrepresentation was material to underwriting.

The most common construction error: classifying a building as Joisted Masonry when the exterior is brick but the roof structure and floor systems are wood. Joisted Masonry requires masonry exterior walls with wood interior supports - many brokers select this class for any brick-exterior building without verifying the roof and floor construction.

Section 3: Occupancy

Occupancy describes what the building is used for. ISO maintains an occupancy classification system that carriers use to assess the hazard class. Common occupancy codes on ACORD 140:

• Mercantile - retail stores, showrooms
• Office - professional offices, administrative buildings
• Habitational - apartments, condominiums, single-family rentals
• Manufacturing - light manufacturing, assembly
• Warehouse - storage, distribution
• Institutional - schools, hospitals, places of worship

Occupancy affects both the rate and the underwriting appetite. A building used as a warehouse for flammable materials occupies a different risk class than a building used for paper storage. Selecting "Warehouse" without disclosing the stored materials class is an underwriting data gap that frequently causes carriers to request supplemental information or decline outright.

Section 4: Protection Class

Protection Class (PC) is ISO's Public Protection Classification - a rating from PC 1 (best fire protection) to PC 10 (no recognized fire protection) assigned to each property location based on proximity to fire departments, fire department staffing and equipment, and municipal water supply adequacy.

Protection Class is not determined by the broker - it is a published ISO classification for each property location. ISO makes PC data available through its FireLine and PPC programs. Carriers purchase this data and apply it automatically when they have the property address. However, brokers often enter a PC on ACORD 140 without verifying the ISO classification for the specific address.

Premium impact of Protection Class: moving from PC 5 to PC 8 for the same commercial building can increase the fire portion of a commercial property premium by 30% to 60%. A PC 10 property (no public fire protection within 5 miles) may be ineligible for standard market commercial property - these properties typically require surplus lines placement.

Section 5: Coverage Section - Limits and Covered Property

This section captures what coverage is being requested:

Building. The limit should represent the replacement cost of the structure (if replacement cost valuation is selected). The building limit does not include the land value - land is not insurable.

Business Personal Property (BPP). Covers furniture, equipment, inventory, and other contents owned by the insured. The BPP limit should be confirmed annually against actual inventory and equipment values. Many insureds underinsure BPP because they estimate rather than inventory.

Business Income / Extra Expense. Coverage for income lost and extra expenses incurred during a property restoration period. The limit should reflect the insured's actual gross earnings exposed during the maximum anticipated restoration period (typically 12 months).

Ordinance or Law. Covers the increased cost of rebuilding to current building codes after a loss. Buildings more than 20 years old in jurisdictions with updated building codes frequently need this coverage. Many ACORD 140 submissions omit Ordinance or Law entirely - a significant coverage gap for older buildings.

Section 6: Valuation Basis

Valuation basis determines how a covered loss is settled. Three bases are commonly used:

Replacement Cost Value (RCV). The carrier pays the cost to replace the damaged property with new property of like kind and quality, without deduction for depreciation. RCV is the standard for most commercial buildings.

Actual Cash Value (ACV). The carrier pays the replacement cost minus depreciation. ACV results in lower payments for older buildings. ACV may be appropriate for properties the insured plans to demolish or significantly modify after a loss.

Agreed Value. The carrier and insured agree on the insured value at policy inception. Agreed value eliminates the coinsurance requirement entirely - the carrier agrees to pay the agreed value without applying a coinsurance penalty. Agreed value requires a separate valuation (appraisal) to establish the agreed amount.

The valuation basis mismatch error. When a broker selects Replacement Cost but fails to conduct or request a replacement cost appraisal, the building may be insured at 60% to 70% of actual replacement cost. At loss, the coinsurance clause reduces the payment proportionally. For a $2 million building insured at $1.2 million with an 80% coinsurance requirement, the carrier would pay only 75% of any covered loss ($1.2M / $1.6M coinsurance requirement). A $400,000 partial loss pays only $300,000.

Section 7: Coinsurance

Coinsurance is the requirement that the insured carry a minimum percentage of the building's replacement cost as coverage. The standard percentage is 80%, but carriers offer 90% and 100% options. A higher coinsurance percentage typically qualifies for a rate credit - and creates a higher underinsurance risk.

Most brokers select 80% coinsurance without explaining the coinsurance concept to the insured or verifying that the coverage limit actually meets the 80% threshold. The ACORD 140 form has a field for the coinsurance percentage - selecting 80% here without adequate limit documentation is one of the top commercial property E&O exposures.

Agreed value as the coinsurance solution. For clients who want coinsurance protection eliminated entirely, the agreed value endorsement (ISO CP 04 02 or equivalent) suspends the coinsurance condition. The insured pays the cost of a periodic appraisal (typically $500 to $2,000 for commercial properties) in exchange for certainty that the coinsurance penalty will not apply at loss.

Section 8: Deductibles

ACORD 140 captures the deductible structure for commercial property coverage. Standard deductibles range from $1,000 to $25,000. High-deductible and large-deductible programs (deductibles of $50,000 to $250,000+) are used for large commercial accounts and require additional underwriting information on the insured's financial capacity to self-fund the deductible exposure.

Special deductibles for wind, hail, and earthquake are applied separately from the all-other-peril deductible. In coastal areas and tornado-prone states, wind/hail deductibles are typically expressed as a percentage of insured value (1% to 5%) rather than a flat dollar amount. ACORD 140 must capture whether the deductible is a flat dollar amount or a percentage - a common error is entering a percentage as a dollar figure or vice versa.

Section 9: Special Coverages and Endorsements

ACORD 140 includes checkboxes for optional or special coverages, including:

• Earthquake coverage (requires separate seismic zone rating)
• Flood coverage (NFIP or private, requires separate application)
• Equipment Breakdown (typically written as a separate policy or endorsement)
• Inland Marine (for equipment off-premises, contractor's equipment, electronic data)
• Spoilage (for refrigerated goods, pharmaceutical inventory)

Carriers including Travelers Commercial Property and Chubb's Commercial Property division require that checked special coverages be accompanied by supplemental underwriting information. Checking "Earthquake" without providing a seismic zone, building age, and construction details will delay the submission.

Common Errors in ACORD 140 Completion

The errors that generate the most carrier declinations and E&O claims:

Wrong construction class for masonry buildings. As noted above, selecting Joisted Masonry for brick-exterior buildings without verifying roof and floor construction is the most frequent construction class error. Verify with the insured or a site inspection before selecting the class.

Missing square footage. Every major carrier requires total building area in square feet for commercial property underwriting. A submission without square footage is returned or declined. Do not estimate - obtain the figure from the insured, building records, or county assessor data.

Valuation basis inconsistent with building age and condition. Selecting Replacement Cost for a 1955 industrial building in poor condition will trigger carrier pushback. ACV or functional replacement cost valuation may be more appropriate, or a current appraisal may be required.

Omitting the occupancy hazard class for warehouse risks. "Warehouse" is too broad for underwriting purposes. Carriers need to know what is stored - the commodity class directly affects the rate and appetite. Failure to specify storage contents is the top cause of warehouse submission incompleteness.

Business Interruption limit based on prior year premium. Some brokers set the Business Income limit at the same dollar figure as the property premium - there is no rational basis for this. The correct Business Income limit is the insured's projected gross earnings for the period of restoration (typically 12 months).

How ACORD 140 Differs From ACORD 24

The critical operational distinction: ACORD 140 is submitted to carriers as part of the new business or renewal quote process. ACORD 24 is issued to mortgage lenders, lessors, and other third parties who need proof that a property policy is in force. An agent who sends an ACORD 24 to a carrier instead of an ACORD 140 has provided evidence of existing coverage - not an application for new coverage. This workflow error delays binding and can cause coverage lapses.

Frequently Asked Questions

What is ACORD 140 used for in commercial property insurance?

ACORD 140 is the commercial property section of the ACORD application suite. It collects building description, construction type, occupancy, protection class, coverage limits, valuation basis, coinsurance percentage, and deductible information for commercial property underwriting submissions. Carriers use ACORD 140 data to assess the risk and generate a premium quote. It is submitted alongside ACORD 125 (General Information page) for new business and renewal submissions.

What is the difference between ACORD 140 and ACORD 24?

ACORD 140 is an underwriting application - it is sent to a carrier before coverage is bound to request a quote. ACORD 24 is an evidence of property insurance form - it is issued to third parties (mortgage lenders, landlords) after coverage is bound to demonstrate that a commercial property policy is in force. ACORD 140 precedes the policy; ACORD 24 follows the policy. Submitting an ACORD 24 to a carrier in place of an ACORD 140 is a workflow error that will delay or prevent binding.

How do ISO construction classes affect commercial property premiums on ACORD 140?

ISO construction classes (Frame, Joisted Masonry, Non-Combustible, Masonry Non-Combustible, Fire Resistive) directly affect commercial property rates. Frame construction (Class 1) is the highest-risk class and carries the highest rate. Fire Resistive (Class 5 or 6) is the lowest-risk class and carries the lowest rate. The premium difference between Frame and Fire Resistive on the same building value can exceed 50% at standard market carriers. Misclassifying a building - particularly selecting a lower-risk class than the structure warrants - is a material misrepresentation that can void coverage at loss.

What valuation basis should I select on ACORD 140?

The correct valuation basis depends on the insured's situation. Replacement Cost Value (RCV) is standard for most commercial buildings - it pays to replace with new property without depreciation deduction. Actual Cash Value (ACV) is appropriate for properties the insured does not intend to rebuild to original condition. Agreed Value is best for insureds who want to eliminate coinsurance exposure entirely - it requires a current appraisal and suspension of the coinsurance clause (ISO CP 04 02). For most commercial clients, RCV with an agreed value endorsement provides the best combination of full recovery at loss and coinsurance protection.

What is the coinsurance requirement on ACORD 140 and how does it work?

Coinsurance requires the insured to carry coverage equal to a specified percentage (typically 80%) of the building's replacement cost. If the insured carries less than the required percentage, the carrier applies a coinsurance penalty that reduces partial loss payments proportionally. Example: an $2 million building with 80% coinsurance requires $1.6 million in coverage. If the policy limit is $1.2 million, partial losses are paid at 75% ($1.2M / $1.6M). A $400,000 loss pays only $300,000. The fix is either an adequate coverage limit or the agreed value endorsement.

What are the most common errors when completing ACORD 140?

The five most common ACORD 140 completion errors are: (1) wrong construction class - particularly selecting Joisted Masonry for buildings where the roof structure is wood but the exterior is masonry; (2) missing square footage, which causes carrier declinations or delays; (3) valuation basis inconsistent with building age and condition; (4) business income limit not tied to actual gross earnings exposure; and (5) omitting the storage commodity class for warehouse risks. Each of these errors either delays the submission, generates carrier requests for additional information, or creates coverage gaps that surface at loss.
