What is the difference between blanket and scheduled commercial property insurance?

Blanket insurance covers multiple locations or property types under a single aggregate limit that can be applied in full to any covered location. Scheduled insurance assigns a specific dollar limit to each location individually — you can only claim up to that location's scheduled amount regardless of total coverage carried. After a major storm that hits one location severely, blanket coverage allows you to apply your full policy limit to that location. Scheduled coverage caps your recovery at that location's specific scheduled amount.

Which is better for coastal commercial properties with storm exposure — blanket or scheduled?

For properties in coastal storm zones, blanket coverage generally provides better protection because it doesn't cap your recovery at any single location. A hurricane that hits your Gulf Coast location with $2M in damage while your scheduled limit for that location was $1.5M leaves you with a $500,000 gap under scheduled coverage. With blanket coverage, the full policy aggregate is available for that loss. The trade-off is that blanket policies typically require higher minimum coinsurance percentages and may require more rigorous property valuations.

Does blanket insurance eliminate the coinsurance penalty?

Not automatically. Blanket policies still typically have coinsurance requirements — often 90% of total value across all insured locations. If your blanket limit is below 90% of the combined replacement cost value of all properties, a coinsurance penalty can still apply. An agreed value endorsement on a blanket policy eliminates the coinsurance penalty for the policy term, similar to how it works on single-property policies.

Blanket vs. Scheduled Commercial Property Insurance

Two Coverage Architectures

Blanket vs. scheduled: how limits are assigned

Commercial property owners with multiple locations face a structural choice in how their coverage is organized:

Scheduled (specific) coverage assigns a fixed dollar limit to each building or location listed in the policy. The schedule might show: Building A (Gulf Coast retail): $1,200,000 / Building B (inland office): $800,000 / Building C (warehouse): $600,000. Total scheduled coverage: $2,600,000. If a hurricane causes $1,800,000 in damage to Building A, you can only collect $1,200,000 — Building A's scheduled limit — even though total policy coverage is $2,600,000.

Blanket coverage places all covered locations under a single aggregate limit. Using the same numbers, a $2,600,000 blanket limit means the full $2,600,000 is available for any single loss. If Building A suffers $1,800,000 in damage, you collect $1,800,000 — no location-specific cap applies.

Why blanket coverage matters after a major hurricane

Hurricane events rarely cause proportional damage across all locations. A major storm hits specific corridors intensely — a direct eyewall passage can cause catastrophic damage to properties in a narrow band while locations 30 miles away suffer only minor damage. Under scheduled coverage, your most exposed location is capped at its individual scheduled limit regardless of actual loss severity. Under blanket coverage, your full aggregate limit is available where the damage is worst.

This concentration risk is particularly acute for:

Coastal retail strips or shopping centers where multiple buildings are in the same storm track
Multi-family or condo portfolios in coastal zones
Commercial portfolios with flagship locations that have higher replacement costs than initially estimated

After Hurricane Beryl (2024), some multi-location Gulf Coast commercial property owners with scheduled policies discovered their heavily-damaged primary location was significantly under-scheduled relative to actual replacement costs — a combination of inflation-driven cost increases and initially conservative scheduling at policy inception.

Blanket coverage requirements and trade-offs

Blanket coverage typically comes with stricter requirements than scheduled coverage:

Higher coinsurance requirements — most blanket policies require 90% coinsurance across the combined value of all locations. Failing to maintain this across the full portfolio triggers the coinsurance penalty on any claim.
Statement of Values — insurers typically require a current Statement of Values (SOV) listing all properties and their replacement cost values. The SOV must be kept current as properties are acquired, sold, or improved.
Annual appraisals — given construction cost inflation (25–40% increase over five years), insurers increasingly require current replacement cost appraisals to support blanket limits. Stale valuations create coinsurance exposure.
Premium structure — blanket premiums are calculated on total aggregate values. If one location has significantly higher risk (coastal vs. inland), the blended rate may be higher than scheduling each location at its individual rate.

FAQ

Blanket insurance questions

I have five commercial properties. Is blanket coverage always better than scheduled?

Not always. If your properties are geographically dispersed across different storm risk zones — say, one Gulf Coast property and four inland properties — the inland locations may get a better rate on scheduled coverage than blended into a blanket policy with the high-risk coastal property. The right answer depends on storm correlation risk (how likely are multiple locations to be hit simultaneously?), the accuracy of your property valuations, and your carrier's pricing. Work with a commercial insurance broker who specializes in multi-location coastal property to model both structures.

My blanket policy has a 90% coinsurance requirement. How do I calculate if I'm meeting it?

Add up the current replacement cost values of all properties in the blanket schedule (using current construction costs, not original purchase prices or assessed values). Multiply by 90%. Your blanket limit must equal or exceed this amount. With construction costs up 30% since 2022, many blanket policies that were adequate at inception are now technically underinsured. An annual replacement cost appraisal from a certified appraiser — not an insurance company estimate — is the most reliable way to verify you're meeting the requirement.

Can I add a new property mid-term to my blanket policy?

Yes, usually — blanket policies are designed to accommodate portfolio changes. Notify your insurer immediately when acquiring a new property. Coverage may apply automatically for a limited period (often 30–90 days) for newly acquired properties, but you must formally add the property and update your Statement of Values to ensure permanent coverage. Failure to add new properties promptly can leave them in a coverage gap or create a coinsurance deficiency that affects your entire portfolio.
