Does Home Insurance Cover Floods and Earthquakes?

Updated June 6, 2026 · 5 min read

Two of the most destructive events a home can face — floods and earthquakes — are not covered by a standard homeowners policy. This surprises homeowners every year, usually at the worst possible moment. Here’s how each works and how to actually get covered.

Why they’re excluded

Floods and earthquakes can cause catastrophic, widespread losses that would bankrupt insurers if bundled into every standard policy. So both are carved out and sold separately, letting people in higher-risk areas pay for the protection they need.

Flood insurance

Standard policies cover some water damage (like a burst pipe) but never rising water from outside — storm surge, overflowing rivers, heavy rainfall pooling, flash floods.

• Where to get it: The federal National Flood Insurance Program (NFIP) or a growing number of private flood insurers.
• Who needs it: If you’re in a high-risk flood zone with a mortgage, your lender requires it. But over a quarter of flood claims come from outside high-risk zones — flooding is the most common natural disaster in the U.S.
• Watch the waiting period: NFIP policies typically have a 30-day waiting period, so you can’t buy one as a storm approaches.

Earthquake insurance

Standard policies exclude earth movement, including earthquakes, sinkholes, and landslides.

• Where to get it: A separate earthquake policy or an endorsement added to your home policy. In California, the California Earthquake Authority (CEA) is the main source.
• How it’s priced: Premiums and deductibles vary widely by region and soil. Earthquake deductibles are usually a percentage of your dwelling limit (often 5–25%), not a flat amount.
• Who needs it: Anyone near a fault line — and the risk isn’t only in California (the Pacific Northwest, Utah, and the New Madrid zone in the central U.S. all have real exposure).

How to decide

Look up your property’s flood and seismic risk, factor in your mortgage requirements, and weigh the cost against the catastrophic downside of being uncovered. Even a moderate-risk home can justify the policy given how total these losses can be.

The bottom line

Your homeowners policy won’t pay for flood or earthquake damage — period. Both require separate coverage, each with its own rules and waiting periods. If either risk applies to where you live, line up the coverage before you need it, and compare both your home policy and these add-ons for the best overall price.
