Key Takeaways
- Standard homeowners insurance generally does not include earthquake damage; check a separate policy or endorsement.
- A percentage deductible can leave a substantial amount for your household to fund.
- Compare building, belongings and other coverages separately, including any separate deductibles.
Earthquake insurance is useful to evaluate by asking what loss the household would keep after the contract pays its covered share. A large stated limit is only one part of the answer. The deductible, covered causes of loss and separate property limits also matter.
Find the coverage before comparing the price
The NAIC’s earthquake-insurance overview explains that earthquake coverage may be sold as an endorsement or a stand-alone policy. Standard homeowners coverage generally does not cover the shaking damage that earthquake insurance is intended to address. Do not assume a general reference to natural disasters adds that protection.
Collect the actual policy wording and endorsements. Identify the home, other structures and belongings you want to insure, then check whether each appears in the coverage schedule. Ask the insurer to explain any difference between the quote summary and the contract.
Calculate the deductible using the stated base
The NAIC’s deductible guidance warns that earthquake deductibles can be substantial and that separate coverages may have separate deductibles. Do not assume the percentage is applied to a repair bill. Confirm the amount or coverage limit to which the percentage applies.
Fictional example: a 15% deductible applied to a stated $300,000 dwelling coverage amount equals $45,000. A hypothetical $12,000 repair bill does not turn that deductible into $1,800. This arithmetic illustrates the specified percentage base; it does not calculate a real claim or recommend a deductible.
Ask how the deductible interacts with the limit and with covered damage to belongings or other structures. Write the answer in dollars where possible. Two quotes with the same premium can leave very different amounts for the household to absorb.
Compare the loss your household would retain
- Which buildings, belongings and additional costs are included?
- Which coverages have separate limits or deductibles?
- How is an event defined, and how are aftershocks treated?
- What exclusions or valuation provisions could change a payment?
- What damage-reporting and inspection requirements apply?
The NAIC notes that a contract can group earthquake events within a specified period and that the period can vary. Check the wording instead of treating a commonly quoted time window as universal. Damage caused by fire, broken pipes or other consequences also needs review under the relevant policy; causation and exclusions matter.
Keep the affordability test realistic
Compare the annual premium with the coverage and the deductible you could actually fund. A lower premium does not solve the problem if a covered loss would leave an unaffordable uninsured amount. Likewise, a cash reserve is not automatically large enough for every catastrophe simply because it covers routine repairs.
Use the insurance coverage checkup to inventory current protection and the emergency-fund guide to separate accessible household reserves from other savings.
Prepare a policy record you can use
Keep the declarations, full wording, endorsements, inventory and verified claims contact in a secure location. Record your questions for a licensed insurance professional or state insurance department. If damage occurs, prioritize safety and follow the insurer’s reporting instructions; a qualified inspection may be necessary to assess damage you cannot see.
