Earthquake vs. Homeowners

In California this pairing matters more than almost anywhere else, because a standard homeowners policy specifically excludes earthquake damage. This page shows what each does and doesn't cover.

Earthquake vs. Homeowners — At a glance
	Earthquake	Homeowners
What it covers	Damage caused by earth movement - shaking, and often resulting damage - to your dwelling, and depending on the policy, contents and loss of use.	Common perils such as fire, wind, theft, and many kinds of water damage, plus liability and additional living expenses - but not earth movement.
When it applies	A quake or earth movement damages your home; sold as a separate policy or endorsement.	An everyday covered peril occurs; it is your base property policy.
Typical cost	Varies with location, soil, and construction; deductibles are percentage-based and can be substantial.	Higher overall, since it bundles many perils - but it explicitly leaves out earthquake.
Key limits or exclusions	Deductible is a percentage of the dwelling limit, not a flat dollar amount; some policies limit contents and exterior features.	Earth movement is a named exclusion - earthquake, landslide, and sinkhole damage are not covered.
Best suited for	California homeowners wanting protection from quake damage, especially in higher-risk areas.	Every homeowner - it is the foundation policy earthquake coverage sits alongside, not inside.

A named exclusion, filled by a separate policy

A standard homeowners policy covers a broad list of perils but deliberately excludes earth movement - meaning earthquake, landslide, and similar ground shifts are not covered. That gap is intentional and appears in the policy's exclusions.

Earthquake coverage fills that gap. In California it is often offered through the California Earthquake Authority (CEA) alongside a homeowners policy, or as a separate policy or endorsement from a private insurer. It sits next to your homeowners coverage rather than being part of it.

Percentage deductibles

Earthquake coverage works differently at claim time. Its deductible is usually a percentage of the dwelling limit - often in the range of 5% to 25% - rather than a flat amount, so on a $500,000 home a 15% deductible means $75,000 comes before the policy pays.

Where to find it in your policy

Your homeowners exclusions

In the policy form, the Exclusions section lists earth movement - confirming earthquake damage is not covered by the base policy.

A separate earthquake Declarations page

Earthquake coverage has its own Declarations - look for a CEA policy or a private earthquake policy or endorsement, with its own dwelling, contents, and loss-of-use limits.

The percentage deductible line

On the earthquake policy, check whether the deductible is stated as a percentage and what dollar figure that translates to for your home.

What it looks like on a real claim

Example 1 — A quake cracks the foundation

An earthquake causes $200,000 in structural damage to a home insured for $500,000, with a 15% earthquake deductible.

Earthquake

Pays the loss above the $75,000 deductible - about $125,000 - up to the policy's limits.

Homeowners

Pays nothing - earth movement is excluded from the homeowners policy.

Example 2 — A kitchen fire after cooking

An unattended stove starts a fire causing $30,000 of damage, with a $1,000 homeowners deductible.

Earthquake

Does not apply - this is a fire loss, not earthquake damage.

Homeowners

Pays $30,000 minus the $1,000 deductible = $29,000, up to policy limits.

The bottom line

Think of the two as partners, not substitutes: homeowners handles everyday perils, and earthquake coverage handles the one your base policy excludes. In California's seismic zones, that gap can be the largest one on the page.

The most common mistake is assuming homeowners quietly includes earthquake. It doesn't - and the percentage deductible means even with coverage, the first large slice of a quake loss is yours to absorb.
