Commercial Property Insurance

Commercial property insurance pays to repair or replace your buildings, equipment and inventory after a covered loss, and business interruption coverage replaces income while you are shut down. This guide explains what it covers, what it leaves out, what drives the price and how to check that your limits are high enough.

The short version
What it is
Insurance that pays for physical damage to buildings, equipment and inventory from covered perils such as fire, theft and wind, and for lost income while you recover.
Who needs it
Anyone who owns or leases space, equipment or inventory. Lenders and landlords usually require it, and data centers and hardware companies depend on it.
Biggest pitfall
Underinsuring. If the limit does not reflect replacement cost, or the valuation or coinsurance terms are wrong, a claim can pay far less than the loss.
What drives price
Building construction and age, location and catastrophe exposure, protection such as sprinklers and alarms, values insured and deductibles.
Typical spend
Priced as a rate on the values insured, so it scales with what you own and where it sits. Coastal and high-hazard locations cost more.
The basics

What is commercial property insurance, in plain English?

Commercial property insurance covers the physical things your business depends on: the building if you own it, the improvements you made if you rent, and the equipment, inventory and furniture inside. When a covered event damages them, the policy pays to repair or replace them.

The second half of the coverage is the one companies forget. Business interruption pays for the income you lose while a covered loss keeps you from operating, along with extra expenses to get back to work faster. For a company with expensive equipment and thin cash reserves, that income coverage often matters more than the building.

Policies list the events they cover, called perils, or cover all risks except those excluded. Either way, the details that decide a claim sit in the valuation method, the coinsurance clause, the deductibles and the exclusions, so they are worth reading before you need them.

Who needs it

Who needs commercial property insurance, and when?

Short answer: any business that owns or leases space, or holds equipment, inventory or prototypes it could not easily replace, needs property coverage. Lenders, landlords and enterprise customers often make it a condition, so the question is usually when, not whether.

The table below maps common situations to what we would typically recommend. It is general guidance, and your lender, landlord or counsel can confirm what a specific agreement requires.

Where you areDo you need it?Why
Remote team, no office, little equipmentOften a light versionCompany laptops and gear are still business property, and personal home policies commonly limit or exclude business equipment. Ask about a small contents policy.
Leasing office or lab spaceYes, usually required by the leaseThe lease normally says who insures the building, who insures your contents and improvements, and what the landlord must be named on. Read those clauses before you sign.
Hardware company with prototypes, tooling or inventoryYes, and watch the valuesPrototypes and test equipment are hard to price and slow to rebuild. Valuation and business income matter as much as the limit.
Owning a building with a mortgageYes, lender requirementLenders typically require replacement cost cover and a mortgagee clause naming them. Many also specify minimum terms for flood where it applies.
Operating a server room, lab or data hallYes, with equipment breakdownMechanical and electrical failure is the common loss, and basic forms exclude it. See the data center section below.
Holding stock in a warehouse or third-party logistics siteYes, check location and transit termsProperty away from your own premises is often covered only up to a sublimit unless scheduled.
Signing enterprise or lender contractsOften, with named wordingContracts may require evidence of property cover, additional insured or loss payee status, and waiver of subrogation. Review them before you sign.
Rule of thumb

Insure what you could not replace out of next month’s cash, and then insure the income you would lose while you rebuild it.

Scope

What commercial property insurance covers, and what it doesn’t

What’s Covered

  • Fire, lightning, explosion, smoke and similar named perils
  • Windstorm, hail and weight of snow, subject to any wind or hail deductible
  • Theft and vandalism of covered property
  • Water damage from sudden events such as a burst pipe or sprinkler discharge
  • Business interruption: lost net income and continuing expenses during the period of restoration
  • Extra expense to keep operating while repairs are made

What’s NOT Covered

Most commercial property insurance policies exclude:

  • Flood and earthquake, which are usually excluded and bought separately
  • Wear and tear, gradual deterioration, rust and corrosion
  • Mechanical or electrical breakdown, unless equipment breakdown coverage is added
  • Employee theft and fraud, which belong on crime insurance
  • Data loss and cyber events, which belong on cyber insurance
  • War, nuclear hazard and intentional damage by the insured
How coverage is triggered

Named perils vs. open perils: which form do you have?

Short answer: a named perils policy covers only the causes of loss it lists, while an open perils policy (often called special form) covers any direct physical loss that is not excluded. Open perils is usually broader, but it is still not unlimited.

With named perils, you must show your loss came from a listed cause such as fire, lightning, windstorm or theft. With open perils, the insurer must point to an exclusion to deny the claim. That reverses the burden in a dispute, which is why many lenders and landlords ask for special form on buildings and equipment.

Named perilsOpen perils (special form)
How it worksCovers only the causes listed in the policyCovers direct physical loss unless an exclusion applies
Who carries the burdenYou show the cause is on the listThe insurer shows an exclusion applies
Typical gapsUnlisted events, accidental damage, some water eventsExclusions such as flood, earthquake, wear and tear, and mechanical breakdown
Where it is commonLower cost or simple forms, some contents-only coversBuildings, equipment and most lender-driven programs

Read the exclusions even on an open perils form. Flood, earthquake, wear and tear, mechanical breakdown and intentional acts are commonly carved out, and some policies add exclusions for specific hazards at your location. See the peril and exclusion definitions for the basics.

Which cover responds?

Which part of a property program responds to what?

Short answer: no single property form pays every loss. Fire is usually covered everywhere, but mechanical failure, flood, earthquake and supplier outages each depend on a specific cover. Pick a scenario to see how it typically maps.

How losses are paid

Replacement cost, actual cash value and agreed value

Short answer: replacement cost pays what it costs to repair or replace damaged property with new, while actual cash value deducts depreciation. For anything that wears out quickly, such as computers and tooling, the difference can be large.

Valuation is the term most likely to surprise a policyholder at claim time, because it is rarely discussed at purchase. The same fire can produce very different payments depending on which method the policy uses. See replacement cost and actual cash value for the definitions.

MethodHow it paysWatch for
Replacement costThe cost to repair or replace with similar new property, without a deduction for ageSome policies pay the full amount only after you actually repair or replace, and may pay actual cash value first.
Actual cash valueReplacement cost minus depreciation for age and wearOlder equipment can pay out a fraction of the cost to replace it. Often the default if nothing else is chosen.
Agreed valueA value you and the insurer settle in advance, which can suspend the coinsurance clauseUsually requires a signed statement of values and periodic updates. Ask what happens if values change mid-term.
Functional or limited valuationPays to replace with something that does the same job, or caps payment at a stated basisCommon for older buildings and obsolete equipment. Know where your assets sit on it.
Rule of thumb

Ask your broker one question about every item on the schedule: if it burned tonight, what would the policy pay, and what would a replacement actually cost?

The penalty clause

Coinsurance: the clause that cuts claims

Short answer: a coinsurance clause requires you to insure property to a stated share of its value. If you carry less, the policy pays a proportionally reduced amount even on a partial loss, so underinsuring can cost you far more than the premium you saved.

Say the clause requires insurance to three quarters of the property’s value, and you carry only half. A claim is then paid at roughly two thirds of what it otherwise would be, before the deductible. The size of the shortfall is the penalty, and it applies to small losses as well as large ones. See coinsurance for the formal definition.

Way to avoid the penaltyHow it worksTrade-off
Insure to the required valueKeep limits at or above the share of value the clause requiresNeeds current, honest valuations every renewal.
Agreed valueThe insurer accepts your stated values in advance and waives coinsurance for the termRequires a statement of values and may need renewal each year.
Blanket limitOne limit spread across locations or classes of property instead of separate limits per itemOften tied to a statement of values and an agreed percentage. Check how it applies per location.
Waive or reduce coinsuranceNegotiate the clause away or to a lower shareUsually costs more premium. Often worth it for volatile values.
Setting limits

How to set property limits step by step

Short answer: start from a list of what you own, price each item at what it would cost to replace today, add the income you would lose while rebuilding, and then check the policy’s sublimits and coinsurance against those numbers. Repeat at every renewal.

List assets

Buildings, improvements, equipment, inventory, furniture, prototypes and anything valuable at other locations.

Step 1

Price replacement

Use current quotes, vendor lead times and installation costs, not purchase price or book value.

Step 2

Add income

Estimate monthly net income plus continuing expenses, and how long a rebuild would really take.

Step 3

Check the policy

Compare limits with sublimits, coinsurance, valuation and deductibles line by line.

Step 4

Update yearly

Re-price after growth, new equipment, inflation in construction and equipment costs, or a move.

Step 5

Two details catch growing companies. First, replacement cost is not the same as purchase price: lead times, shipping, installation and compliance work can add to the bill. Second, a single limit for the whole schedule may sit far below what you hold at one location. Ask whether limits are per location, blanket or scheduled.

Rule of thumb

Re-price your equipment list whenever you add a major asset or move. A schedule that was right at inception can be too low within a year.

Lost income

Business income and extra expense: how they pay out

Short answer: business income coverage pays lost net income and continuing expenses while a covered loss stops or slows your operations, after a short waiting period and up to the end of the period of restoration. Extra expense pays the added cost of keeping operating, such as renting temporary space.

Coverage starts only if physical damage from a covered cause is what stopped you. A slow customer quarter, a regulator’s order or a cloud outage generally does not qualify, unless the policy specifically extends it. See business interruption for the basics.

Loss happens

A covered event damages your premises or equipment and operations stop or slow.

Day 0

Waiting period

A time deductible, typically measured in hours or days, before income cover begins.

Early

Period of restoration

Income and continuing expenses are paid while you repair, rebuild or relocate with reasonable speed.

Main phase

Extended period

Some policies add a tail while customers return and sales recover to normal.

Recovery

What counts as business income?

Net income you would have earned, plus normal operating expenses that continue, such as payroll you choose to keep and rent. Policies differ on payroll for ordinary employees.

Why it matters: Companies with high payroll and low revenue should confirm how payroll is treated.

What is extra expense?

The additional cost of keeping operating after a loss, such as temporary space, rented equipment or expedited shipping, up to the limit.

Why it matters: It can shorten the shutdown and reduce the income claim, so it is often worth its own limit.

How long is the waiting period?

It varies by policy and is usually stated in hours or days. A shorter wait typically costs more premium.

Why it matters: Confirm whether it counts from the date of damage or the date operations actually stop.

What is the period of restoration?

The time until the property should be repaired or replaced, or operations resume elsewhere, with reasonable speed.

Why it matters: It is not how long it actually takes you. Long lead times for specialty equipment should be raised early.

Pre-revenue companies often ask whether business income applies to them. It can, but it depends on how the policy measures income and whether continuing expenses are covered. Ask your broker how a company with little revenue and large burn would be treated. Some policies cover continuing expenses even when net income is thin, but wording varies.

Equipment and infrastructure

Equipment breakdown, data rooms and high-value gear

Short answer: equipment breakdown cover pays for sudden mechanical or electrical failure of equipment, which basic property forms commonly exclude. Companies with server rooms, labs, test rigs or data centers usually need it.

The losses most likely at a technology company are rarely fires. They are failed cooling, power surges, burned-out controllers and short circuits. These are the exact events that equipment breakdown is written for, often including spoilage and the extra expense of expediting repairs.

Equipment breakdown

Pays for sudden physical damage to covered equipment from mechanical failure, electrical arcing or pressure events, with repair or replacement.

Why it matters: It is the difference between losing a rack to a failed cooling unit and getting paid for it.

Data and software restoration

Basic property forms usually cover the hardware, not the data or software on it. Some forms add limited restoration cost.

Why it matters: Recreating lost data and configurations can cost more than the machine. Cyber cover often handles data loss, so check how they fit together.

High-value and specialty equipment

Prototypes, lab instruments, GPU clusters and unusual machines may need to be scheduled with agreed values and clear lead times.

Why it matters: Standard limits can undercount the real replacement cost and the time to get a replacement delivered.

Utility service interruption

Covers damage or lost income when power, water or telecom service fails at the source rather than at your site. Often needs to be added.

Why it matters: Data and compute operations depend on power, so ask whether the cover includes off-premises power failure.

Data centers have additional questions: redundancy, uptime commitments to tenants, and values for specialty equipment that can reach into the millions. Our data center insurance guide walks through those, and the data centers industry page covers how we place them.

Rule of thumb

If your business cannot run without a piece of equipment, ask whether its failure is covered, how fast it can be replaced, and whether the policy pays for expediting.

Dependency risk

Contingent business interruption: suppliers, customers and cloud

Short answer: contingent business interruption pays lost income when damage at someone else’s location, usually a named supplier or customer, stops your operations. Your own policy does not do this unless it is extended to do so.

A hardware startup that depends on one contract manufacturer is the classic example. If that plant has a fire, your own premises are untouched and standard business income does not respond. See contingent business interruption for how forms usually work.

DependencyWhat often appliesQuestion to ask
Single-source component or contract manufacturerContingent business income, usually naming the supplier or a class of suppliersIs the supplier named or covered by class, and does the cause of loss need to be physical damage?
Key customer that buys most of your outputCustomer-side contingent cover, if offeredIs there a sublimit and how is loss of sales measured?
Cloud or hosting providerOften not covered by property policies, which generally need physical damageCyber or tech cover may respond to some outages. Ask what each policy calls a covered event.
Utility or logistics providerUtility service interruption, and sometimes transit-related extensionsDoes it cover off-premises failure and for how long?

A pure software outage at a cloud provider is typically not physical damage, so property cover is unlikely to respond. Cyber and technology policies sometimes address system failure and dependent business interruption, and wording varies a lot. Read cyber and tech E&O alongside your property policy to see where the gap is.

Natural catastrophe gaps

Flood and earthquake: why they need separate cover

Short answer: standard commercial property policies typically exclude flood and earthquake, so cover for them is bought separately or added by a specific endorsement. Whether you need it depends on where your property sits and what a loss would cost.

The exclusion catches companies that assume “water damage” means all water damage. A burst pipe is a sudden internal event and is usually covered. Rising water from rain, rivers or surge is flood and usually is not. The same split applies to ground movement, such as earthquake and some landslide events.

Flood

Rising surface water from rain, rivers or tides is typically excluded from standard property forms. Separate flood cover is available, often with its own limits and waiting periods.

Why it matters: Lenders may require flood cover on mortgaged property in mapped hazard areas. Check your lender’s terms.

Earthquake

Ground shaking and related movement are typically excluded. Separate earthquake cover usually carries a percentage deductible and its own limit.

Why it matters: Even small shaking can disrupt equipment, so businesses in exposed regions should price it rather than assume.

Wind and hail

Usually covered, but often with a separate or percentage deductible in exposed regions.

Why it matters: Know the deductible dollar amount before storm season so there are no surprises.

Sublimits

Where flood or earthquake is included, it is often sublimited well below the main limit.

Why it matters: Check the sublimit against what you would need to rebuild and reopen.

A broker can help you decide whether the exposure at your locations justifies the premium. For catastrophe-exposed property, the answer is often yes, and for buildings inland on higher ground it may be a closer call. Either way, make the decision on purpose rather than by default.

Renting space

Tenant improvements and leased space requirements

Short answer: if you rent, the landlord insures the building but you usually insure your contents and the improvements you paid for, and the lease often sets minimum requirements. Read the insurance and casualty clauses of the lease before you sign.

Tenant improvements are build-outs such as walls, flooring, cabling, labs and clean rooms that you installed. Whether they are the landlord’s property or yours, and who must insure them, depends on the lease. A fire that destroys a new lab build-out can leave you paying for it if no one insured it.

Improvements and betterments

Cover for the build-out you paid for as a tenant, often as a separate coverage line on the policy.

Why it matters: Without it, you may pay for the lab again while the lease still requires rent.

Additional insured and loss payee

Landlords and lenders often require to be named on your policy for certain interests.

Why it matters: Missing wording can put you in default on the lease, so confirm exact wording with your broker.

Waiver of subrogation

Often required so your insurer cannot pursue the landlord after paying you, and vice versa.

Why it matters: Check it is endorsed on the policy, not just promised in the lease. See waiver of subrogation.

Coverage for landlord property

Some leases make you responsible for damage you cause to the building or its systems.

Why it matters: That is usually a liability question, so review general liability alongside property.

Certificates of insurance are the usual proof. Our guide on what clients and lenders require on a COI explains what they typically look for.

Property that moves

Property in transit and inland marine

Short answer: standard property forms mainly cover property at your premises, with limited cover off site. Property that travels, sits at job sites or trade shows, or is stored with others is usually handled through transit cover or inland marine.

Inland marine is a broad class of cover for movable property and goods in transit by land, despite the name. For technology companies, it often fits portable equipment, demo units, field gear and shipments to customers.

Equipment away from your premises

Laptops, demo units and field equipment carried to customer sites, events or home offices.

Why it matters: Limits for off-premises property under a standard form are usually low, so scheduled equipment may be needed.

Goods in transit

Shipments of inventory or equipment moving by truck, courier or air, sometimes insured by the carrier only up to a limited amount.

Why it matters: Carrier liability is often capped well below the goods’ value, so check whether your policy tops it up.

Installation and job sites

Equipment installed at a customer or construction site before it is accepted.

Why it matters: The question is who bears risk, the customer, a contractor or you. Contracts and builder’s risk can decide it.

Stored with others

Inventory held at a warehouse, fulfillment partner or contract manufacturer.

Why it matters: Confirm the other party’s own insurance and whether your policy covers stock at that address.

Ask for these

Property enhancements worth asking about

Short answer: beyond the base form, the features we raise most often are equipment breakdown, extra expense, utility interruption, ordinance or law, debris removal and valuation terms. Each is usually an endorsement or sublimit, so check what is actually included.

Equipment breakdown

Covers sudden mechanical and electrical failure, which basic forms often exclude.

Why it matters: For labs and server rooms it is often the loss most likely to happen.

Ordinance or law

Pays extra cost to rebuild to current building codes after a covered loss, not just to the old standard.

Why it matters: Older buildings can require upgrades that a standard replacement cost payment does not include.

Debris removal

Pays to clear damaged property from the site after a loss, often with its own limit.

Why it matters: Clean-up can be a large share of a big claim, so check the limit.

Utility service interruption

Covers damage or lost income from off-premises power, water or telecom failure.

Why it matters: Operations that rely on power should confirm it applies beyond a short outage.

Extended period of indemnity

Continues business income after repairs are complete while sales recover.

Why it matters: Customers do not always return the day you reopen.

Valuation and agreed value

Replacement cost valuation, with agreed value where values are stable.

Why it matters: It decides how much you get and whether coinsurance applies.

Property of others

Covers customer or partner property in your care.

Why it matters: Hardware companies often hold others’ equipment for testing or repair.

Loss payee and additional insured wording

Names lenders, landlords or customers where required.

Why it matters: Contracts commonly require it, and wrong wording can breach them.

What changes over time

How property needs change as you grow

Short answer: property exposure grows with every new lease, piece of equipment and inventory build, and replacement values drift with market costs. Review limits at least annually, and again after any move, major purchase or change in what happens inside the building.

What changesWhat to do
You add a location or moveNotify your broker before you move. Check that the new address is covered and that catastrophe exposure and lease requirements have been reviewed.
You buy major equipmentAdd it to the schedule with current replacement cost. Check lead times and whether it needs special wording.
Costs of construction or equipment riseUpdate replacement values so limits and coinsurance still hold.
Your revenue grows or shrinksRe-run the business income worksheet and the period of indemnity needed.
Claims or renewal arriveExpect underwriters to ask about loss history and what you changed afterward. See loss runs.
The market hardensExpect higher rates or deductibles in catastrophe-exposed regions. Early renewal conversations help.

If you stop operating or sell a building, coverage ends and so does any lender or landlord requirement. Cancel only after confirming nothing remains insurable, such as stock in storage, equipment awaiting sale or property still in transit.

What claims look like

Three property claims that test the policy

Scenario 01

The fire in the lab

What happenedA fire started in a shared electrical panel at a hardware company’s leased lab, destroying prototypes and test equipment and closing the space for ten weeks.

The claimProperty damage to equipment and inventory, plus lost income during the shutdown.

What respondedProperty coverage paid to replace the equipment, and business interruption paid continuing expenses and lost net income through the restoration period.

Scenario 02

The burst pipe versus the flood

What happenedA pipe burst overnight and damaged inventory in a warehouse. Separately, heavy rain pushed water in through the loading dock in the same month.

The claimTwo water losses with different causes.

What respondedThe burst pipe was covered as a sudden water event. The rain flooding was excluded because flood requires its own policy, which the company had not bought.

Scenario 03

The cooling failure in the server room

What happenedA cooling unit failed in a small data room, overheating servers and switches worth several hundred thousand dollars.

The claimDamage to equipment from a mechanical failure, with no fire or outside cause.

What respondedOnly a policy with equipment breakdown coverage responded. A basic property form would have excluded the loss as mechanical breakdown.

Scenarios are illustrative composites based on common claim patterns, not specific Alton Risk clients. Whether a real claim is covered depends on the policy wording and the facts.

When it happens

How to document a property claim and what to expect

Short answer: report the loss quickly, protect the property from further damage, keep damaged items until the adjuster has seen them, and gather proof of what you owned and what the shutdown cost. Policies usually have notice conditions, so delay can create problems.

Report

Notify your broker and insurer promptly and note the date and time of discovery.

First

Protect

Take reasonable steps to prevent further damage and keep receipts for them.

Next

Document

Photograph and list damage, gather purchase records and evidence of values.

Then

Adjust

An adjuster inspects, reviews the numbers and issues a position, often in stages.

Review

Evidence of ownership and value

Invoices, asset registers, serial numbers and photos of equipment and stock.

Why it matters: It speeds the claim and supports replacement cost values.

Business income proof

Financial statements, payroll records, sales history and a record of continuing expenses.

Why it matters: Income claims are paid on numbers you can demonstrate, so tidy records help.

Mitigation

Steps you took to limit damage, such as moving stock or boarding openings.

Why it matters: Policies expect reasonable steps, and costs are often recoverable.

Proof of loss and cooperation

Many policies require a signed statement and cooperation with inspection or examination.

Why it matters: Deadlines apply, so ask your broker what your policy requires.

Your insurer may also pursue whoever caused the loss, which is called subrogation. Do not sign a release with a third party before checking with your broker, as it could affect your own claim. Learn what to expect in first notice of loss.

Rule of thumb

Before a loss, photograph your equipment and keep an up-to-date asset list somewhere that survives a fire at the building. It is the cheapest claim help you can buy.

Pricing

What moves the price of commercial property insurance?

Property is priced as a rate applied to the values you insure, so the same building can cost very differently depending on where it sits and how it is protected.

FactorWhy it moves your premium
Values insuredThe more you insure, the higher the premium. Accurate replacement cost values matter, because underinsuring creates a coinsurance penalty at claim time.
Construction, age and roofFire-resistive construction and recent updates to the roof, wiring and plumbing lower the rate.
Location and catastrophe exposureWind, hail, wildfire and flood exposure raise price and can add separate deductibles or exclusions.
ProtectionSprinklers, monitored fire and burglar alarms and nearby fire protection reduce risk.
Occupancy and operationsWhat happens inside matters. Labs, manufacturing and data halls rate differently from offices.
DeductiblesHigher deductibles lower premium, and wind and hail often carry their own percentage deductible.
Business interruption periodA longer period of indemnity and a shorter waiting period cost more but protect more.
Getting covered

How to get property insurance quoted without delay

Short answer: bring a statement of values, building details and your business income figures, and be upfront about location hazards and loss history. Missing details usually lead to conservative terms or a slower quote.

What to have ready

  1. Addresses and your relationship to each: own, lease or storage.
  2. A list of equipment and inventory with replacement values, including high-value and specialty items.
  3. Building details: year built, construction, roof, wiring and plumbing updates.
  4. Protection: sprinklers, alarms, security and any fire or flood mitigation.
  5. Business income worksheet: revenue, fixed costs and realistic time to rebuild.
  6. Lease and lender insurance clauses, including required wording.
  7. Loss history, plus a summary of any upgrades since.

What delays a quote most often?

Missing values, unclear occupancy, unreported catastrophe exposure and last-minute lease requirements.

Why it matters: Each is avoidable with a short checklist before you go to market.

What mistakes cost companies the most?

Insuring at purchase price, ignoring coinsurance, assuming flood or breakdown is included, and not updating values after growth.

Why it matters: These are typically the reasons a claim pays less than expected.

Can a package policy be enough?

Small, low-value operations may fit a package that combines property and liability, though limits and exclusions need reading.

Why it matters: Check that the package covers equipment breakdown, business income and your lease terms. See quick quotes for GL and workers’ comp.

From the carrier’s side of the table

What underwriters ask before they quote

A property submission needs more than an address. Carriers price the building, the contents and the location separately, and missing details usually lead to conservative terms.

  • A statement of values for buildings, contents, equipment and inventory, on a replacement cost basis.
  • Construction details: year built, number of stories, construction type and roof age.
  • Protection: sprinklers, alarms, security and fire department distance.
  • Occupancy: what the space is used for and who else is in the building.
  • Business income figures: revenue, fixed costs and how long you would need to rebuild.
  • Loss history for the last five years.
  • Lease or lender requirements, including loss payee and additional insured wording.
Self-audit

Questions to ask about your current policy

  1. Are values insured on a replacement cost basis, not actual cash value?
  2. Do the limits reflect current rebuild and equipment costs, or last year’s?
  3. What does the coinsurance clause require, and are you meeting it?
  4. How long is the waiting period and the period of indemnity on business interruption?
  5. Do you have equipment breakdown, flood and earthquake coverage if you are exposed to them?
  6. Do wind and hail carry a separate percentage deductible, and could you absorb it?

If you can’t answer yes to all of them, book a short coverage review (opens in a new tab) and we will read the policy with you.

Frequently Asked

Common questions

What does commercial property insurance cover?

+

Commercial property covers physical damage to your buildings, equipment, and inventory from perils such as fire, theft, and weather, and typically includes business interruption for lost income while you recover. Builder's risk covers structures under construction.

What is business interruption coverage?

+

Business interruption replaces income you lose when a covered event shuts down operations, and can cover the extra expense of keeping the business running. For data centers and capital-intensive operations, structuring BI correctly is critical.

Do data centers need specialized property coverage?

+

Yes. Data center property programs must address equipment breakdown, redundancy, uptime obligations to tenants and hyperscalers, and high-value contents, which requires carriers who understand mission-critical infrastructure.

What is builder's risk insurance?

+

Builder's risk covers buildings and materials during construction or renovation. It is usually required by lenders and contracts, and we align limits and terms to those requirements.

What is the difference between replacement cost and actual cash value?

+

Replacement cost pays what it costs to repair or replace damaged property with new, while actual cash value subtracts depreciation for age and wear. Replacement cost generally costs more in premium but pays more at claim time, and some policies only release the full amount once you actually replace the property.

What is coinsurance and how does the penalty work?

+

Coinsurance is a clause that requires you to insure property to a stated share of its value. If you carry less, the insurer typically reduces every covered claim in proportion to the shortfall, even for partial losses, so underinsuring can cost much more than the premium saved. Agreed value or a waiver of the clause can avoid it.

What is the difference between named perils and open perils?

+

A named perils policy covers only causes of loss it lists, while an open perils policy covers direct physical loss unless an exclusion applies. Open perils is typically broader and shifts the burden to the insurer to show an exclusion, but it still excludes things such as flood, earthquake and wear and tear.

Does commercial property insurance cover flood or earthquake?

+

Typically not. Standard commercial property policies usually exclude flood and earthquake, so they are bought separately or added by endorsement, often with their own limits and deductibles. Whether you need them depends on where your property is and what a loss would cost to repair.

How long is the waiting period on business interruption coverage?

+

It varies by policy and is usually stated in hours or days. The waiting period works like a time deductible, so income during that window is typically not paid. A shorter waiting period usually costs more premium, so check how it is measured in your policy.

What is extra expense coverage?

+

Extra expense pays the added costs of keeping your business operating after a covered loss, such as temporary space, rented equipment or faster shipping. It can reduce the income lost in a shutdown, and some policies give it its own limit separate from business income.

Does my landlord’s insurance cover my equipment and improvements?

+

Usually not. A landlord’s policy generally covers the building, not your contents or the improvements you paid for as a tenant. The lease decides who insures what, so confirm those clauses and consider coverage for your equipment, inventory and build-out.

Do I need property insurance if my team works remotely?

+

Often yes, in a lighter form. Company laptops, hardware and inventory kept at homes or storage are still business property, and personal home policies commonly limit or exclude business equipment. A small contents policy or scheduled equipment can address that, depending on the policy wording.

Is equipment in transit or off site covered?

+

It depends. Standard property forms mainly cover property at your premises, with limited cover for property elsewhere. Equipment that travels, ships or sits at job sites is typically handled through transit cover or inland marine, and carrier liability for shipped goods is often capped below true value.

What is contingent business interruption?

+

Contingent business interruption pays lost income when damage at a supplier’s or customer’s location stops your operations, rather than damage at your own. It is usually added to a policy and may need the supplier named or described by class. Ask how your policy defines a covered event.

Does property insurance cover a cloud or hosting outage?

+

Typically not. Property policies generally require direct physical damage, and a pure software or network outage at a provider is not physical damage. Cyber and technology policies sometimes address system failure and dependent outages, but wording varies, so read them together.

What documents do I need to file a property claim?

+

Expect to provide proof of ownership and value such as invoices, asset lists, photos and serial numbers, plus business income records like financials and payroll. You may also need a signed proof of loss. Report the loss promptly, protect the property and keep damaged items until the adjuster inspects them.
