Commercial Property Insurance

Coverage built around the building, occupancy, values, income, and lease obligations.

Insurance guidance for California commercial building owners, lessors-risk operations, apartment owners, commercial condominiums, and eligible mixed-use properties.

Commercial property insurance begins with the building and who occupies it.

Construction, age, roof, electrical, plumbing, HVAC, fire protection, occupancy, tenants, cooking, vacancy, maintenance, location, catastrophe exposure, and replacement cost all influence eligibility and program structure.

We organize the submission around accurate property data, tenant use, valuations, income, leases, loss control, and the coverage requirements imposed by lenders or ownership agreements.

Commercial property risks we can evaluate

Lessor's Risk

Nonresidential buildings leased to eligible office, retail, service, warehouse, or other qualifying tenants.

A Connected Property Program

Coverage should follow the building, income, equipment, liability, and ownership obligations.

Property limits alone do not address every exposure. Valuation, income, ordinance, equipment, liability, catastrophe, and umbrella coverage should be coordinated.

Building Coverage

Covered direct physical loss to the insured building and qualifying attached property, subject to causes of loss and valuation.

Building

Business Income & Rents

Qualifying lost rental income, continuing expenses, and extra expense following a covered suspension.

Income

General Liability

Eligible premises and operations liability, including covered bodily injury or property damage allegations.

Liability

Ordinance or Law

Selected increased costs arising from enforcement of building codes after a covered loss, subject to limits and terms.

Codes

Equipment Breakdown

Mechanical, electrical, pressure-system, and qualifying building-equipment breakdown exposures.

Systems

Crime & Cyber

Selected employee, funds-transfer, computer, privacy, and building-management technology exposures where appropriate.

Crime

Flood & Earthquake

Catastrophe protection generally requiring separate coverage or endorsements and individual underwriting.

Catastrophe

Umbrella or Excess

Additional limits over eligible premises, auto, employer, and other scheduled liability policies.

Limits

Valuation and Business Income

The limit should reflect what rebuilding and interruption could actually cost.

Market value, loan balance, tax value, and replacement cost measure different things. Construction costs, demolition, code upgrades, professional fees, debris, lead times, and income restoration should be considered.

Replacement cost

Building characteristics, local construction costs, quality, foundations, attached structures, and special features inform the estimate.

Coinsurance and valuation

Replacement cost, actual cash value, agreed value, functional valuation, and coinsurance provisions can materially affect recovery.

Restoration period

Permits, design, demolition, contractor availability, materials, code compliance, and tenant buildout can extend downtime.

Rental income

Current rents, vacancy, lease terms, tenant turnover, continuing expenses, and restoration assumptions support the limit.

Tenant operations can change the risk

A building insured as office or light retail can change materially when a tenant introduces cooking, manufacturing, automotive work, hazardous materials, cannabis, entertainment, or vacancy. Lease and notification procedures matter.

Association property is not the same as an individually owned building

A condominium association master policy, an individual commercial unit, and a building owner's lessors-risk policy can have different responsibilities. Governing documents and ownership should be reviewed before deciding which page or market applies.

Preparing for Underwriting

A complete commercial-property submission answers four questions.

Accurate building, occupancy, value, and loss-control information reduces preventable underwriting delays.

What is the building?

Construction, age, square footage, stories, roof, wiring, plumbing, HVAC, protection, and updates.

Who occupies it?

Owner or tenants, operations, occupancy percentages, cooking, hazards, vacancy, and lease responsibilities.

What values and income are exposed?

Building replacement cost, contents, rents, business income, equipment, improvements, and restoration time.

What external requirements apply?

Lenders, leases, ownership entities, condominium documents, catastrophe concerns, limits, and renewal timing.

Documents to Prepare

Give the underwriter a complete picture.

Commercial-property review is strongest when building data, occupancy, valuations, and insurance history agree.

Property

Building and updates

Statement of values, construction details, roof and system ages, updates, protection, photos, inspections, and maintenance.

Occupancy

Tenants and income

Tenant schedule, operations, leases, rent roll, vacancy, cooking or hazards, business income, and ownership entities.

Insurance

Policies and losses

Current declarations and forms, five years of currently valued loss runs when available, lender requirements, and requested limits.

Frequently Asked Questions

Questions commercial property owners often ask.

How should a commercial building insurance limit be selected?

The limit should be supported by a current replacement-cost estimate considering construction, size, quality, special features, local costs, demolition, code requirements, and other rebuilding expenses. Market value and loan balance are not substitutes for replacement cost.

What is lessors-risk insurance?

Lessor's risk generally refers to insurance for a building owner leasing premises to others. Eligibility and coverage depend on the building, tenants, operations, leases, values, protection, and loss history.

Does commercial property insurance include earthquake or flood?

Not automatically. Earthquake and flood are commonly excluded or limited under standard property forms and may require separate policies or endorsements subject to underwriting.

Why does an insurer need a tenant schedule?

Tenant operations affect fire, liability, theft, water, hazardous-material, cooking, vacancy, and catastrophe exposure. The schedule also helps verify occupancy and rental-income assumptions.

What should a building owner prepare for an insurance review?

Prepare the current policy, loss runs, statement of values, construction and system details, roof and update information, tenant schedule, rent roll, photos, inspections, leases, lender requirements, and desired coverage.
