Commercial Property Insurance

Commercial property insurance pays to repair or replace a business's building and its contents after a covered event. How much it covers depends on which of three causes-of-loss forms the policy uses, and how much it pays depends on whether the property is insured at replacement cost or actual cash value.

Quick Summary

  • It is first-party coverage: it pays for the business's own property, not for claims other people make against the business.
  • Three levels exist. Basic and broad forms cover a named list of causes; the special form covers all direct physical loss except what the policy excludes.
  • The difference between named-peril and open-peril is who has to prove what. Under a named-peril form the business shows the cause is on the list; under the special form the insurer shows it is excluded.
  • Replacement cost pays to rebuild at today's prices. Actual cash value pays replacement cost minus depreciation, which on older property can be far less than the cost of replacing it.
  • Flood, earth movement, and coastal wind are commonly excluded and bought separately. A flood policy has a waiting period before it takes effect.

Definition

Commercial property insurance is first-party coverage for a business's own physical assets. The Texas Department of Insurance states the scope in one sentence: "Commercial property insurance pays to repair or replace your building and business property damaged by a fire, storm, or other event covered by the policy. It can also pay some of your lost income if your business is unable to operate normally." The National Association of Insurance Commissioners uses the line name "commercial property" and notes it is "also known as business property insurance", describing coverage that "protects the business's location and physical property, such as equipment, inventory, and furniture."

It is worth being precise about what "property" reaches, because it is broader than the building. NAIC's list of what business property may include, whether owned or leased, runs to "the actual building", inventory, "furniture, equipment and supplies", machinery, "computers and other data processing equipment", "valuable papers, books and documents", artwork and antiques, and "signs, fences and outdoor property not attached to a building." A business that rents its premises still has most of that list to insure, and NAIC's own advice on that point is direct: "If you lease your building or office, do not rely on your landlord to provide coverage for your business property. The building typically is insured only for the basic structure and common areas."

Advanced Explanation

The three causes-of-loss forms, and the burden-of-proof flip that is the real difference. The single most consequential choice in a commercial property policy is which of three levels of covered causes it uses, and two regulators describe the ladder in the same terms.

The Texas Department of Insurance sets it out this way. "Basic form policies provide the least coverage. They usually cover damage caused by fire, windstorms, hail, lightning, explosions, smoke, vandalism, sprinkler leakage, aircraft and vehicle collisions, riots and civil commotion, sinkholes, and volcanoes." Broad form policies "usually cover the causes of loss included in the basic form, as well as damage from leaking appliances, structural collapses, falling objects, and weight of ice, sleet, or snow." And "special form policies provide the most coverage. These policies usually cover damage from all causes of loss, except those specifically listed in the policy." NAIC gives the same structure independently, describing the special form as including "basic and broad form coverage plus all other direct physical losses except conditions specifically excluded and listed in the policy."

The practical difference is not just a longer list. Basic and broad are named-peril forms: the policy responds if the cause of loss appears on its list, and the business has to establish that it does. The special form is an open-peril form: everything physical is covered unless the policy excludes it, and it is the insurer that has to point to the exclusion. For an unusual or hard-to-diagnose loss, that difference in who carries the argument can matter more than the difference in the lists.

What the special form excludes is therefore where the reading has to happen. According to the Department, "most policies exclude damages from floods, earth movement, war, nuclear disaster, wear and tear, and insects or vermin." Wear and tear is the one businesses trip on most often, because a slow failure is often the thing that eventually causes visible damage.

Replacement cost versus actual cash value, applied to a business. The Department states the choice and its consequence together: "Commercial property policies provide either replacement cost coverage, actual cash value coverage, or a combination of both." Replacement cost coverage "pays to repair or replace your property at current costs. This means the policy will pay enough to rebuild your building and replace your property with new items, even if the cost is more than what you originally paid." Actual cash value coverage "pays replacement cost minus depreciation", and the Department is blunt about the result: "If you have actual cash value coverage, the policy might not pay enough to fully rebuild your business." NAIC describes the same pair, defining actual cash value as reimbursing "the assessed value lost, damaged or stolen goods after depreciation".

The choice bites hardest on the assets a business has held longest and would have to replace immediately. Depreciated computers, a fifteen-year-old refrigeration unit and worn shelving are precisely the items whose actual cash value is a small fraction of what a replacement costs, and they are also the items a business cannot operate without. A policy written on a combination basis, replacement cost on the building and actual cash value on contents, is common and is worth identifying, because the contents are usually where the gap is.

The coinsurance clause, and why under-insuring costs more than the shortfall. A commercial property policy typically requires the business to carry insurance equal to a stated percentage of the property's value. NAIC describes the mechanism: it is "a clause contained in most property insurance policies to encourage policy holders to carry a reasonable amount of insurance," and "if the insured fails to maintain the amount specified in the clause (usually at least 80%), the insured shares a higher proportion of the loss."

The consequence for a business is proportional rather than absolute, and this is the part that surprises people: a business insured for half of what the clause requires does not merely hit its limit sooner, it has every partial loss reduced in proportion. A $40,000 fire on a building insured at half the required amount is not a $40,000 claim; it is a fraction of one, before the deductible. Since a total loss is capped by the policy limit anyway, the clause's bite falls almost entirely on the partial losses that make up most claims. NAIC's practical advice follows from that: "have your business property value assessed before you buy, and periodically after you purchase insurance", because the value the clause is measured against moves with construction costs.

What the policy does not include, and where each of those lives instead. A business reading a commercial property policy for the first time is usually surprised by the size of this list, and the Department enumerates it:

  • Flood. "Most commercial property policies don't cover damage from flooding," and a separate policy is needed. Note the timing trap: "There's a 30-day waiting period after you buy a flood policy before the coverage goes into effect", so it cannot be arranged when weather is forecast.
  • Coastal wind and hail, in the states that carve it out. The Department tells a business on the Texas coast or in Harris County on Galveston Bay that its policy "probably doesn't cover wind and hail damage", and directs it to the state windstorm association, which "won't sell you a policy if there's a hurricane in the Gulf of Mexico." That is Texas's arrangement. Which coastal states exclude wind from the standard policy, and what residual market stands behind it, is a question about the individual state.
  • Crime. Separate coverage exists for "robbery and safe burglary", "forgery and alteration", "employee theft", "cyber crime", and "money and securities, which insures money, securities, and other property against losses that happen on or off your business site."
  • Inland marine, which despite the name "covers property kept on land, not on water", and reaches accounts receivable, computers, contractor equipment, fine art, property in transit, valuable papers, and property held for others.
  • Lost income. Business interruption coverage "pays for the income you lose if your business can't operate normally", and extra expense coverage "pays additional costs to return your business to normal after it's damaged." These are additions rather than components.
  • Code upgrades. Ordinance or law coverage "pays extra construction or repair costs to meet current building codes", which is the gap that turns a covered rebuild into a partly uninsured one for an older building.
  • Equipment breakdown. Boiler and machinery coverage reaches "boilers, air conditioning units, compressors, steam cookers, electric water heaters, and similar machinery."

How to Remember

Three questions decide what a commercial property policy is worth: which causes it covers, whether it pays new-for-old or depreciated, and whether you carried enough to satisfy the coinsurance clause.

Used in a Sentence

“The bakery's commercial property insurance replaced the two ovens and the walk-in cooler after the electrical fire, though the eleven-year-old mixer was settled at actual cash value and came in $6,400 short of a new one.”

How It Works

  1. The business values its property, building and contents, at what it would cost to replace. This is the figure the coinsurance clause is measured against, not the purchase price and not the tax-assessed value.
  2. It chooses a causes-of-loss form. Basic, broad or special, which determines both the range of covered causes and who has to prove what.
  3. It chooses a valuation basis, replacement cost or actual cash value, and may choose differently for the building and the contents.
  4. It sets limits and a deductible. A higher deductible lowers the premium and raises the out-of-pocket cost on any claim.
  5. It adds the coverages the base policy excludes where the exposure applies: flood, coastal wind, crime, inland marine, business interruption, ordinance or law, equipment breakdown.
  6. It re-values periodically, because construction costs move and the coinsurance percentage is measured against current replacement cost.

A hypothetical works the coinsurance arithmetic, which is where a policy most often disappoints. Vasquez Upholstery occupies a building with a replacement cost of $900,000. Its policy carries an 80 percent coinsurance clause and a $5,000 deductible, and the business insured the building for $500,000 because that is what it paid for it years ago.

  • The clause requires 80% × $900,000 = $720,000 of coverage.
  • The business carries $500,000, so the ratio is $500,000 ÷ $720,000 = 0.6944.
  • A partial loss of $120,000 is settled at 0.6944 × $120,000 = $83,333, less the $5,000 deductible, so $78,333 is paid.
  • The business absorbs $41,667 of the $120,000 loss, of which $36,667 is the coinsurance shortfall and $5,000 is the deductible.

Now the two comparisons that make the point. Had the building been insured at the full $720,000, the same loss would have been settled at $120,000 less the deductible, so $115,000. And had the loss instead been a total one, the $500,000 limit would have capped the claim anyway, so the coinsurance calculation would have added nothing. That is why the clause's real effect is on partial losses, which are most losses.

The figures are illustrative, and the exact settlement formula is the one written into the policy's own coinsurance condition, which differs in detail between commercial and homeowners forms. The mechanism is not illustrative: a coverage shortfall is applied as a proportion of every partial claim for as long as the under-insurance lasts, which is why a stale property valuation is expensive in a way that does not show up until there is a claim.

Pros and Cons

Pros

  • Covers the assets a business cannot operate without, including inventory, equipment and records, not merely the building.
  • The special form shifts the burden of proof to the insurer, which matters most for the unusual losses hardest to attribute to a named cause.
  • Replacement cost coverage keeps pace with construction and equipment prices, so a long-held building is not underinsured by inflation alone.
  • Available to a tenant as well as an owner, which is the coverage a leased business most often assumes the landlord provides and does not.
  • Bundled into a businessowners policy for most small businesses, which is generally cheaper than buying the parts separately.

Cons

  • The exclusions are extensive and include the perils many businesses most fear: flood, earth movement, and coastal wind and hail in exposed areas.
  • Flood coverage has a waiting period, so it cannot be bought in response to a forecast.
  • Actual cash value settlement on contents can leave a large gap on older equipment, which is the equipment a business is least able to do without.
  • The coinsurance clause reduces every partial claim in proportion to any under-insurance, so a stale valuation is a hidden reduction in coverage rather than a smaller policy.
  • Lost income is not included. A covered physical loss that shuts the business for six weeks produces no income replacement without separate business interruption coverage.
  • Basic and broad forms leave the business to establish the cause was on the list, which is a real disadvantage when the cause is disputed.

People Also Asked

Answers to the most frequently asked questions.

What is the difference between basic, broad and special form?
They are three levels of covered causes of loss. The Texas Department of Insurance describes basic form as covering a named list including fire, windstorm, hail, lightning, explosion, smoke, vandalism, sprinkler leakage and vehicle collision; broad form as adding causes such as leaking appliances, structural collapse, falling objects, and weight of ice, sleet or snow; and special form as covering "damage from all causes of loss, except those specifically listed in the policy." The structural difference is that under the first two the business shows the cause is covered, while under the special form the insurer shows it is excluded.
Should I buy replacement cost or actual cash value coverage?
Replacement cost pays to repair or replace "at current costs", while actual cash value "pays replacement cost minus depreciation." The Texas Department of Insurance advises that "to be fully protected, make sure your policy provides replacement cost coverage", and notes that under actual cash value "the policy might not pay enough to fully rebuild your business." The gap is widest on older contents, which is also usually the equipment a business has to replace immediately to reopen.
Does commercial property insurance cover flood damage?
Generally no. The Texas Department of Insurance states that "most commercial property policies don't cover damage from flooding", and that a separate flood policy is needed, available from insurers that sell it or from the National Flood Insurance Program. There is a timing trap worth knowing: "There's a 30-day waiting period after you buy a flood policy before the coverage goes into effect", so the coverage cannot be arranged once a storm is forecast.
What does the coinsurance clause do to my claim?
It reduces every partial claim in proportion to any shortfall in coverage. NAIC describes it as a clause "to encourage policy holders to carry a reasonable amount of insurance," under which, "if the insured fails to maintain the amount specified in the clause (usually at least 80%), the insured shares a higher proportion of the loss." Because a total loss is capped by the policy limit regardless, the clause's effect falls almost entirely on partial losses, which is why keeping the insured value current matters more than it appears to.
If I lease my premises, do I still need this?
For the contents, almost certainly. NAIC's advice is direct: "If you lease your building or office, do not rely on your landlord to provide coverage for your business property. The building typically is insured only for the basic structure and common areas." A tenant's inventory, equipment, furniture, records and improvements are the tenant's to insure, and the lease may impose further requirements or penalties, so it is worth reading alongside the policy.
