Earthquake DIC Coverage
Named-peril earthquake protection for the loss your standard property policy won't touch.
This is an estimate, not a bound policy — a licensed VAB producer confirms final terms before coverage starts. Sgt. Savings can answer questions but can't quote, bind, or guarantee coverage.
Most commercial property policies either exclude earthquake entirely or cap it so low it barely matters. Earthquake DIC (Difference in Conditions) coverage fills that specific gap — a standalone, named-peril policy that pays for direct physical damage from earth movement, written to sit primary, alongside your existing property policy, or as excess above a lower earthquake sublimit. It's built for one job and does it well.
Who This Is Really For
The ideal buyer.
The ideal buyer already owns or manages commercial property in a mapped seismic zone and has read the fine print on their standard policy closely enough to find the earthquake sublimit — usually a figure that would barely cover cosmetic repairs, let alone a real structural loss. Many have already asked their existing property carrier about raising that sublimit and found it either unavailable or priced high enough that a standalone DIC layer made more sense. The trigger is often external and specific: a lender making earthquake coverage a condition of a refinance or new loan, a portfolio acquisition that adds a building in a fault zone, or simply running the numbers on what a total-loss quake scenario would actually cost against what the existing policy would actually pay. This buyer isn't shopping for earthquake coverage in the abstract — they're closing a gap they can point to on their own declarations page. A generic add-on endorsement rarely fits because it's usually capped low by design; this buyer needs a policy structured to sit primary, DIC, or excess specifically around what they already carry.
- Commercial property owners in California, the Pacific Northwest, or the New Madrid seismic zone whose standard policy either excludes earthquake or caps it far below the building's value
- Owners of unreinforced masonry, tilt-up, or soft-story buildings — construction types earthquake underwriters price and inspect closely
- Lenders requiring earthquake coverage as a loan condition on a property in a mapped seismic zone
- Portfolio owners who want a DIC layer wrapped around several locations instead of negotiating earthquake limits property-by-property
- Businesses that ran the numbers on a total-loss earthquake scenario and didn't like what a bare property policy would actually pay
What It Covers
Coverage, broken down.
Direct physical damage from earth movement
Pays for physical loss or damage to the described building and its contents caused by earthquake — ground shaking, fault rupture, and earth movement generally, on an occurrence basis.
Primary, DIC, or excess placement
Structured to fit around what you already carry: written as the primary earthquake policy where you have none, as a Difference in Conditions layer that fills a gap in an existing policy's terms, or as excess sitting above an existing earthquake sublimit.
State-specific terms
Policy terms are adjusted state by state to match each state's earthquake insurance requirements and disclosure rules, so the coverage that binds is the coverage that's actually enforceable where the building sits.
Illustrative Scenario — How This Coverage Responds
Illustrative scenario — a tilt-up warehouse after a moderate quake
A distribution business owns a tilt-up concrete warehouse near a mapped fault line. Its standard commercial property policy has a $250,000 earthquake sublimit — nowhere near what it would cost to repair the building's structure. A magnitude 6 quake cracks several tilt-up panels and shifts the building's foundation enough to require structural repair. Under an illustrative Earthquake DIC layer sitting excess above that $250,000 sublimit, the additional repair cost above the sublimit is what the DIC policy is designed to respond to — subject to its own limit, deductible, and the terms of the schedule. This is a walkthrough of how the coverage is structured, not a claim outcome or dollar figure VAB is promising.
Illustrative example for education only — not a claim outcome or a promise of payment. Every claim depends on the actual policy issued and its terms.
More Than One Way In
More scenarios.
Real coverage doesn't fit one story. Here's who else this shows up for.
The lender-mandated retrofit building
A borrower refinancing a tilt-up commercial building is told by the lender that earthquake coverage is a condition of closing, since the standard property policy's sublimit falls well short of the loan amount. The owner schedules a DIC layer sized to satisfy the lender's requirement rather than negotiating a higher sublimit directly with the existing property carrier. This is an illustration of a common trigger for buying this coverage, not a claim outcome.
The portfolio owner consolidating limits
An owner with several properties spread across a seismic zone has been negotiating earthquake terms building by building, with inconsistent sublimits across the portfolio. Wrapping one DIC layer around the whole schedule gives a consistent effective limit at every location instead of a patchwork of separately negotiated terms. This scenario illustrates how the coverage can be structured across a portfolio, not a specific outcome.
The mid-retrofit building owner
An owner is partway through a seismic retrofit on an older soft-story building and wants coverage in place during the transition, since the building is neither fully vulnerable nor fully upgraded. The DIC policy is placed to reflect the building's current condition, with terms expected to improve once the retrofit is complete and documented. This illustrates how construction status factors into placement, not a specific quote or outcome.
Know The Gaps
What this doesn't cover.
Every policy has limits. Knowing them before you buy is how you avoid a denied claim later.
Fire or explosion following the quake
Fire-following-earthquake is typically a standard fire policy's job, not this policy's — confirm your fire coverage doesn't have its own earthquake-related exclusion or you can end up with neither policy responding.
Flood, including quake-triggered flooding or tsunami
A seismic event can trigger flooding (broken water mains, tsunami in coastal zones) that this policy treats as flood, not earthquake — flood needs its own policy.
Land movement and land-stabilization issues not tied to a covered earthquake
Slow ground settlement, slope failure, or soil instability that isn't the direct result of a seismic event falls outside a named-peril earthquake form.
Wear and tear or non-seismic settlement
A cracked foundation from age or poor original construction isn't an earthquake loss just because it's discovered after a quake — the crack has to be caused by the seismic event.
Faulty design or workmanship
If a building fails because it wasn't built to code or seismic standard, that's a construction-defect issue, not something this coverage is meant to underwrite.
Seismic events before the policy started or after it ends
Coverage is occurrence-based and dated — a pre-existing crack from a quake before your policy incepted doesn't become a covered loss just because you now carry this policy.
Dishonest or criminal acts
Standard fraud exclusion — this is property coverage for a natural peril, not a crime policy.
Behind The Quote
What goes into the decision.
What actually moves your price and your approval — no black box.
Construction type
Unreinforced masonry, tilt-up, and older soft-story wood-frame buildings perform worst in a real seismic event, so underwriters price and inspect them the most closely — a documented retrofit to a recognized seismic standard is the concrete step a buyer can take to improve terms.
Proximity to a mapped fault or seismic zone
Location relative to known fault lines and seismic hazard maps (California, the Cascadia zone, the New Madrid zone) drives both availability and pricing, since it sets the baseline probability and severity of a covered event at that specific address.
The existing property policy's own earthquake terms
Whether the DIC layer needs to sit primary, fill a gap, or sit excess above an existing sublimit depends entirely on what the underlying property policy already does — sharing that policy's actual earthquake language at application is what lets the DIC layer be structured to actually respond where the underlying policy stops.
Retrofit and code-compliance status
A building retrofitted to a recognized seismic standard, or built to current code, is a materially different risk than an unretrofitted older structure of the same type — documentation of any retrofit work is worth providing at application even if it isn't yet complete.
State-specific disclosure and requirements
Earthquake insurance rules vary by state, so the policy's terms and required disclosures are adjusted to where the property actually sits — confirming the property's exact location and any state-specific requirements early avoids surprises at binding.
Getting Covered
How it actually works.
- Tell us the building's construction type, location, and current property/earthquake coverage (if any).
- We structure the policy to sit primary, DIC, or excess based on what you already carry.
- Terms and the state disclosure package are finalized for the state the property sits in.
- After a seismic event, you report the loss and an adjuster evaluates direct physical damage against the schedule.

Questions, answered straight
No jargon on earthquake dic coverage — just what you're actually asking.
Most standard commercial property forms either exclude earthquake outright or cap it at a small sublimit, because the potential loss from a major seismic event is large and geographically concentrated. Earthquake DIC exists specifically to fill that gap without forcing you to replace your entire property program.
Difference in Conditions. It's a policy written to cover the gap between what your existing property policy covers and what a fuller earthquake policy would cover — either broader perils, higher limits, or both, layered on top of what you already have.
Yes, if flood is a real exposure for the property. Earthquake and flood are underwritten and priced as separate perils industry-wide, and this policy specifically excludes flood, including flood triggered by an earthquake.
It's placed nationwide, with terms adjusted to each state's requirements — that includes the Pacific Northwest's Cascadia zone and the New Madrid seismic zone in the central U.S., not just California.
Unreinforced masonry and older soft-story wood-frame buildings typically draw the most underwriting scrutiny and the highest pricing, because they perform worst in a real seismic event. Retrofitted or newer code-compliant buildings generally place more easily.
Beyond This Coverage
What people in your situation also need.
Commercial Real Estate Financing
The same building carrying the earthquake exposure is often also being purchased, refinanced, or leveraged, and a lender frequently requires earthquake coverage as a financing condition.
ExploreBusiness Banking
A commercial property owner in a seismic zone typically already needs an operating banking relationship to manage reserves for the property's deductible and ongoing upkeep.
