Here’s the detail that catches the most homeowners off guard: standard homeowners insurance excludes both flood and earthquake damage entirely. No policy on the market bundles full flood and earthquake protection into a standard package — both require a separate policy or endorsement, purchased on top of your regular coverage. That doesn’t mean it’s hard to get, but it does mean you have to actively add it, and the right insurer for flood coverage isn’t always the right one for earthquake coverage. Here’s how to find both in 2026.
Quick Answer: Best Options for Flood and Earthquake Coverage

*Availability and pricing for flood and earthquake coverage depend heavily on your specific location and risk zone — always confirm current options directly with the carrier or program.
Why Standard Home Insurance Doesn’t Cover This
Flood damage is excluded under virtually every standard homeowners and renters insurance policy. Coverage is available separately, primarily through the National Flood Insurance Program (NFIP), managed by FEMA, or through a smaller number of private flood insurers. One detail that surprises a lot of homeowners: more than 20% of flood claims come from properties located in low-to-moderate risk zones, not just officially designated high-risk flood areas — meaning «I’m not in a flood zone» isn’t the same as «I can’t flood.»
Earthquake coverage works similarly — it’s available from most insurers as either a standalone policy or an endorsement added to your homeowners policy, but it isn’t included standard. Since the 1900s, earthquakes have occurred in 39 states, and an estimated 90% of Americans live in areas considered seismically active, yet only a small percentage of homeowners actually carry earthquake insurance.
One more important nuance: each policy only covers its specific peril. Earthquake insurance pays for damage directly caused by seismic activity — cracked foundations, structural damage — but if the earthquake also causes a fire, that fire damage is typically covered under your regular homeowners policy instead. Similarly, flood insurance covers rising water, not water damage from a burst pipe inside your home, which falls under standard homeowners coverage.
USAA — Best Overall Combination
USAA is frequently well-positioned to help members access both flood insurance (via NFIP referral or private options) and earthquake endorsements in eligible states, combined with the strong overall customer satisfaction USAA is known for across its home insurance products.
Pros:
- Strong support accessing both flood and earthquake coverage in one place
- High customer satisfaction and claims service ratings
- Competitive overall home insurance pricing for eligible members
Cons:
- Membership eligibility limited to military-affiliated households
- Specific flood/earthquake product availability still varies by state
Best for: Eligible military-affiliated homeowners who want a single point of contact for both flood and earthquake coverage questions.
Allstate — Best Earthquake Endorsement Availability
Allstate offers earthquake endorsements more widely across states than many competitors, making it a practical option for homeowners in moderate seismic risk areas who want to add coverage without switching to a completely separate specialty insurer.
Pros:
- Wide availability of earthquake endorsements across states
- Strong digital tools for managing multiple coverage add-ons
- Solid bundling options with auto insurance
Cons:
- Flood coverage still typically requires a separate NFIP or private policy
- Earthquake deductibles (set as a percentage of dwelling coverage) can be substantial
Best for: Homeowners in moderate seismic-risk areas who want to add earthquake coverage to an existing Allstate policy.
State Farm — Best CEA Partner (California)
In California specifically, State Farm is one of the participating insurers through which homeowners can purchase a California Earthquake Authority (CEA) policy — a state-backed, non-profit program created specifically to make earthquake coverage more available and standardized across the state.
Pros:
- Direct access to CEA earthquake policies for California homeowners
- Extensive local agent network to help navigate flood and earthquake add-ons
- Strong overall financial strength and availability
Cons:
- CEA earthquake coverage is only available in California
- Flood coverage still requires a separate NFIP or private policy nationwide
Best for: California homeowners who want to add CEA earthquake coverage through a familiar national insurer.
Liberty Mutual — Best Water Backup + Earthquake Bundle
Liberty Mutual offers water backup coverage — a related but distinct add-on covering damage from sewer or drain backups, which neither standard home insurance nor flood insurance typically covers — alongside earthquake endorsements in eligible areas, letting homeowners address several water- and seismic-related gaps in one place.
Pros:
- Water backup coverage available alongside earthquake endorsements
- Helps address multiple common coverage gaps together
- Established national insurer with broad availability
Cons:
- Flood coverage itself (for rising water) still requires a separate NFIP or private policy
- Specific endorsement availability varies by state
Best for: Homeowners who want to address water backup risk and earthquake risk together, in addition to standard flood coverage elsewhere.
Auto-Owners — Best Inland Flood Add-On
Auto-Owners offers an optional inland flood coverage add-on directly through its homeowners policy in low- or moderate-risk flood zones, letting eligible homeowners skip a completely separate NFIP application for more modest flood exposure.
Pros:
- Inland flood add-on available directly through the homeowners policy in eligible zones
- Competitive standard home insurance pricing, including for older homes
- Strong customer service reputation where available
Cons:
- Only available in a limited number of states, sold through independent agents
- High-risk flood zones still generally require a full NFIP or private flood policy instead
Best for: Homeowners in low- or moderate-risk flood zones who want a simpler, bundled flood add-on rather than a fully separate policy.
Chubb — Best for High-Value Homes
Chubb offers flood and earthquake coverage options as part of its broader high-value home insurance program, alongside the extended replacement cost and high liability limits it’s known for — a strong fit for homeowners who need comprehensive protection across multiple risks on a higher-value property.
Pros:
- Flood and earthquake add-ons integrated with comprehensive high-value coverage
- Strong claims service reputation
- Complimentary risk consultant services in some cases
Cons:
- Best suited to higher-value homes; not the most cost-effective option for standard properties
- Sold primarily through agents rather than direct online quotes
Best for: Owners of high-value homes who want flood and earthquake coverage integrated with broader comprehensive protection.
Neptune Flood — Best Private Flood Specialist
Neptune Flood is a private flood insurance specialist offering fast digital quotes and, in many cases, higher coverage limits than the National Flood Insurance Program’s standard caps — a strong option for homeowners who want more coverage or a faster process than the traditional NFIP application.
Pros:
- Fast, fully digital quote and application process
- Higher coverage limits available than standard NFIP policies in many cases
- Coverage available even in some areas NFIP doesn’t fully serve
Cons:
- Pricing and availability depend heavily on your specific flood risk profile
- As a private insurer, terms differ from the standardized NFIP policy — read the specifics carefully
Best for: Homeowners who want higher flood coverage limits or a faster process than a traditional NFIP policy.
California Earthquake Authority (CEA) — Best Dedicated Earthquake Program
The CEA is a state-backed, not-for-profit program (not a private insurer) that provides the majority of homeowners earthquake insurance in California, purchased only through CEA’s participating insurance companies. Deductibles are available at 5%, 10%, 15%, 20%, or 25% of the dwelling coverage limit, with homes valued above $1 million or built before 1980 on certain foundation types restricted to the higher deductible tiers unless retrofitted.
Pros:
- Dedicated, standardized earthquake program specific to California’s seismic risk
- Multiple deductible tiers to fit different budgets and risk tolerance
- Discounts available for retrofitted homes, up to 25% off premiums
Cons:
- Only available in California, through participating insurers
- Deductibles are percentage-based and can represent a large out-of-pocket amount
Best for: California homeowners who want a standardized, state-backed earthquake program rather than a private insurer’s individual offering.
How We Chose These Companies {#how-we-chose}
InsureAtlas’s rankings are based on publicly available information: each carrier’s or program’s disclosed availability of flood and/or earthquake coverage, deductible structures, third-party financial-strength ratings (AM Best) where applicable, and published consumer research on pricing and service quality. No insurer can pay to appear higher on this list, and our rankings are not based on affiliate commission rates. Because flood and earthquake coverage availability depends enormously on your specific state and risk zone, we recommend confirming current options directly with a carrier, agent, or the relevant state program (like the CEA) before deciding.
How to Get the Right Flood and Earthquake Coverage
Don’t assume you’re not at risk because you’re not in an official flood zone. More than 1 in 5 flood claims comes from properties in low-to-moderate risk areas — a preferred risk flood policy is often available at a lower cost for these zones.
Check whether your mortgage lender requires flood insurance. Lenders typically require it if your home is in a high-risk flood zone (FEMA Special Flood Hazard Area), though you can still choose to buy it voluntarily elsewhere.
Understand earthquake deductibles are different. Unlike standard homeowners deductibles, earthquake insurance deductibles are usually a percentage (often 5-25%) of your dwelling coverage limit, not a flat dollar amount — a 5% deductible on a $400,000 dwelling limit is $20,000 out of pocket.
Buy building and contents coverage separately if needed. Standard flood insurance policies typically require separate applications for building coverage and contents coverage — confirm you’re covering both if you want your belongings protected, not just the structure.
Ask about retrofit discounts for earthquake coverage. In California, verified seismic retrofits can qualify homeowners for meaningful discounts (up to 25%) on CEA earthquake premiums — worth confirming if your home has had retrofit work done.
Frequently Asked Questions
Does homeowners insurance cover flood damage? No. Flood damage is excluded from virtually all standard homeowners and renters insurance policies. Coverage is available separately through the National Flood Insurance Program or a small number of private flood insurers.
Does homeowners insurance cover earthquake damage? No. Earthquake coverage must be purchased as a standalone policy or as an endorsement added to your homeowners policy — it isn’t included in standard coverage.
If an earthquake causes a fire, is the fire damage covered? Generally, yes — but under your regular homeowners policy, not your earthquake insurance. Earthquake policies typically only cover damage directly caused by the seismic event itself; resulting fire damage usually falls under standard homeowners coverage.
Am I required to have flood insurance? Only if your mortgage lender requires it, which is typically the case if your home sits in a FEMA-designated high-risk flood zone. Outside those zones, flood insurance is optional, though it remains available and often worth considering given how many claims come from lower-risk areas.
How much does earthquake insurance typically cost? Cost depends on your location, deductible percentage, dwelling coverage limit, and home’s construction and foundation type. Because deductibles are percentage-based rather than flat amounts, it’s worth calculating your realistic out-of-pocket exposure at different deductible levels before choosing a policy.
Bottom Line
There’s no single «best» flood-and-earthquake insurer for every homeowner, largely because the right option depends heavily on your specific state and risk zone. USAA and Allstate offer strong overall access to both coverage types for eligible or widely available markets, California homeowners have a dedicated path through the CEA and its participating insurers like State Farm, and Neptune Flood is worth a look if you want higher flood limits or a faster process than a standard NFIP policy. Whatever your location, the most important step is simply recognizing that neither peril is covered by a standard policy — confirm your actual exposure and shop for the specific add-on coverage you need rather than assuming your existing homeowners policy already has you protected.
