Earthquake Insurance Considerations for Apartment Owners
- 5 days ago
- 6 min read
Owning apartment buildings can be highly profitable—but it also comes with risks that many investors underestimate. One of the most overlooked exposures we see at Wexford Insurance is earthquake risk, especially because it’s not automatically included in a standard policy.
In Nate Jones’s experience as a former underwriting manager, apartment owners often don’t even realize they have a coverage gap until a lender, broker, or loss event forces the conversation. “Earthquake insurance is one of those coverages that gets ignored right up until the moment it becomes critical—and by then, options can be limited or expensive,” says Nate Jones, CPCU, ARM, CLCS, AU.
If you own, manage, or invest in multifamily properties, understanding how earthquake exposure impacts your apartment insurance program can make the difference between protecting your long-term asset—or taking on devastating financial loss.
Average Cost of Earthquake Insurance for Apartment Buildings
Earthquake insurance is almost always written separately from your standard commercial property insurance or as an endorsement. Costs vary widely depending on construction type, location risk scores, and building characteristics.
Below are realistic estimated ranges based on what we see working with apartment owners nationwide.
$500 to $2,500 annually per small-to-mid-size property
Larger portfolios: $2,500 to $10,000+
Does not include earthquake damage

What Factors Affect Earthquake Insurance Costs for Apartment Owners
Earthquake pricing is one of the most technical areas of insurance underwriting. Unlike general liability or auto policies, this coverage depends heavily on engineering-level details.
Here’s what underwriters evaluate:
Construction Type
Wood-frame properties typically perform better during seismic activity than unreinforced masonry. Soft-story buildings (with open parking levels) often face stricter underwriting scrutiny.
At Wexford Insurance, we’ve seen older unreinforced buildings either:
Get significantly higher premiums, or
Be declined by standard carriers entirely
Building Age and Retrofit History
Older apartment buildings without seismic retrofits are considered higher risk.
If your property has had upgrades—like bolting foundations or reinforcing structural walls—it can significantly improve your underwriting profile.
Soil Conditions
Soil plays a major role in earthquake damage severity.
Soft soils amplify shaking
Rocky or stable soils reduce movement
Carriers often use third-party seismic risk modeling tools to assess this.
Replacement Cost Valuation
Earthquake deductibles are tied to total building value.
For example:
$5 million building
15% deductible
= $750,000 out-of-pocket before coverage applies
Nate Jones, CPCU, ARM, CLCS, AU often emphasizes this point:
“A lot of owners focus on premiums but ignore the deductible math. On earthquake policies, your retention is what really matters.”
Building Height and Layout
Mid-rise and high-rise buildings tend to have more complex structural risk. Larger footprints and irregular shapes can also impact pricing.
Portfolio Size and Carrier Appetite
If you own multiple apartment buildings, carriers may:
Offer better pricing through portfolio bundling
Or limit capacity depending on geographic spread
Earthquake-Specific Insurance Requirements for Apartment Owners
Unlike some other coverages, earthquake insurance is rarely mandated universally—but that doesn’t mean it's optional in practice.
Lender Requirements
Many lenders require earthquake coverage as a condition of financing, especially for:
Newly acquired properties
Refinanced loans
Larger multifamily complexes
At Wexford Insurance, we regularly step in when a borrower is days away from closing and realizes coverage is required.
Deductible Threshold Expectations
Some lenders will:
Cap acceptable deductible levels
Require specific coverage limits
This is critical because a policy that satisfies insurance requirements might still fail lender conditions.
Building Code Considerations
Older buildings may need to meet updated structural standards during reconstruction—even if earthquake retrofits weren’t previously required.
This can create:
Higher rebuild costs
Longer repair timelines
Business Interruption Expectations
Lenders and investors often expect coverage for:
Loss of rental income
Extended downtime during repairs
Without this, even an insured property can produce zero revenue for months.
Regulatory Oversight
Insurance products, including earthquake policies, are regulated by individual states through their Departments of Insurance.
You can learn more about how these policies are typically structured through the Insurance Information Institute.
How to Lower Your Apartment Insurance Costs (Including Earthquake Coverage)
While earthquake risk can’t be eliminated, there are smart steps you can take to reduce costs and improve insurability.
1. Invest in Seismic Retrofits
Foundation bolting
Structural reinforcements
Soft-story mitigation
These improvements can noticeably reduce premiums.
2. Adjust Deductibles Strategically
Choosing a higher deductible lowers premiums—but increases risk.
At Wexford Insurance, we often balance this by aligning deductibles with your:
Cash reserves
Risk tolerance
3. Maintain Accurate Property Valuations
Outdated valuations can:
Inflate premiums
Cause claim issues
We recommend periodic replacement cost reviews.
4. Bundle Policies When Possible
Combining:
Property
Liability
Workers comp
can improve overall pricing.
5. Document Risk Improvements
Keep records of:
Structural upgrades
Maintenance history
Engineering evaluations
Underwriters reward documented risk management.
6. Work With an Independent Insurance Agency
An independent agency like Wexford can:
Access multiple carriers
Compare coverage options
Negotiate better terms
7. Review Coverage Before Major Events
Before:
Acquisitions
Refinancing
Expansion
Insurance should always be reviewed proactively—not reactively.
FAQ: Earthquake Coverage for Apartment Buildings
Is earthquake insurance included in standard apartment insurance?
No. Earthquake coverage is almost always excluded from standard commercial property insurance policies and must be purchased separately or added by endorsement.
Why are earthquake deductibles so high?
Deductibles are based on a percentage of total building value, not a flat amount. This reflects the potential severity and widespread damage associated with seismic events.
Do all apartment owners need earthquake insurance?
Not always—but many lenders require it, and certain property types face a higher risk profile. It ultimately depends on your investment strategy and risk tolerance.
Does earthquake insurance cover loss of rental income?
Only if you add business interruption (loss of rents) coverage. This is not always included automatically and should be carefully reviewed.
Can older apartment buildings still qualify for coverage?
Yes, but with limitations. Older buildings often face higher premiums, stricter underwriting, or require specialty carriers.
How long does it take to process an earthquake claim?
These claims often take longer than standard property claims because:
Structural assessments are required
Engineering reports must validate damage
The process can take months depending on severity.
What’s the biggest mistake apartment owners make?
In Nate’s experience:
“The most common mistake is assuming ‘it won’t happen here.’ Earthquake exposure doesn’t care about assumptions—it’s about risk modeling and financial readiness.”
Why Apartment Owners Choose Wexford Insurance

We’re not tied to a single carrier. As a Trusted Choice independent agency, we represent multiple insurance companies, which allows us to shop the market and find the best combination of coverage and price.

We’ve worked with apartment owners across the country—from small 6-unit buildings to large multifamily portfolios—and we’ve seen firsthand how earthquake coverage decisions impact long-term financial outcomes.
Recently, we helped a property owner who was refinancing a mid-size apartment complex. Their lender required earthquake insurance with specific deductible limits. The existing policy didn’t meet those terms, and closing was at risk.
