The 5 Coverage Gaps We Find Most Often in Commercial Property Policies

Most coverage gaps are not the result of a bad policy. They develop quietly, as a property changes and the policy does not change with it. A few appear often enough to be worth checking on any commercial property program.

1. Outdated building values

The most common gap and usually the most expensive. Construction costs have risen substantially in recent years while many insured values have been carried forward largely unchanged.

The consequence is not simply a shortfall at the top end. Coinsurance provisions require you to insure to a stated percentage of full value, commonly 80 or 90 percent, and falling short lets the carrier reduce payment on partial losses proportionally. A building insured at 70 percent of its required value may recover roughly 70 percent of a covered partial claim, which is why this shows up on ordinary claims and not just catastrophic ones.

How to close it: obtain a current replacement cost valuation and update it annually rather than applying a percentage increase to an older figure.

2. Missing or insufficient ordinance and law coverage

When an older building is damaged, current building codes typically apply to the repair. That can require upgrades the original structure never had, and in some cases can require demolition of undamaged portions of the building that no longer conform.

Standard property policies frequently exclude or heavily sublimit these costs. Ordinance or law coverage is usually written in three parts, and knowing which you have matters:

• Coverage A: the value of the undamaged portion you are required to demolish.
• Coverage B: the cost of that demolition and debris removal.
• Coverage C: the increased cost of construction to bring the rebuild up to current code.

Coverage C is where the largest dollars usually sit, and it is also where sublimits are most often too small.

How to close it: confirm all three parts are present and that the Coverage C limit is realistic for your building's age and jurisdiction. Older buildings in stricter code jurisdictions carry the largest exposure.

3. Business income and extra expense that no longer match reality

Business income coverage, called loss of rents on many commercial property policies, replaces income while the property is being repaired. Extra expense covers the additional costs of operating during that period, such as temporary space or expedited shipping on materials.

Two things commonly go stale. The rent roll has grown since the limit was set, and the realistic rebuild timeline has lengthened because of permitting delays and contractor availability.

The timeline piece is governed by the period of restoration, the window during which the carrier will pay. Twelve months is a common default, and complex or large rebuilds frequently run longer. An extended period of indemnity endorsement continues payments for a set time after the property reopens, recognizing that tenants and revenue do not return the day the doors unlock.

How to close it: set the limit from your current rent roll, confirm the period of restoration is realistic for your building type and jurisdiction, and consider whether an extended period of indemnity fits.

4. Water backup and flood assumptions

Property policies almost universally exclude flood, defined as rising surface water, and separately exclude water that backs up through sewers or drains unless a water backup endorsement is added. Owners frequently assume one addresses the other. They are separate exclusions requiring separate solutions, and flood generally requires a standalone policy through the NFIP or the private market.

Flood zone designations also change over time as FEMA remaps areas. A property mapped outside a high risk zone at acquisition may sit inside one today, and lender requirements can change with it.

How to close it: verify the current flood zone designation, confirm whether water backup coverage is in place, and check its sublimit, which is often far lower than owners expect.

5. Unverified tenant and vendor insurance

Leases and service contracts routinely require tenants and vendors to carry insurance and to name the owner as an additional insured, meaning your entity is added to their policy so their insurer responds when their activity causes a loss. Those requirements only function if certificates of insurance, or COIs, are collected, reviewed, and kept current.

A certificate is a snapshot showing coverage existed on the date issued, so a file full of expired COIs provides limited protection. It is also worth confirming that additional insured status was actually endorsed onto the policy rather than simply typed onto the certificate.

When a tenant's or contractor's coverage has lapsed, the loss frequently returns to your program, affecting both the claim payment and the loss runs that shape your pricing for years afterward.

How to close it: maintain a tracking process with renewal reminders, and verify additional insured status rather than relying on the certificate alone.

What this means for you

None of these gaps are exotic and none require a specialty policy to address. They persist mainly because nothing prompts a review until a claim does. An annual coverage check against how the property actually operates today catches most of them well before that point.
