Zone X Flood Insurance: Is Optional Coverage Worth It?
Flood insurance is not required in Zone X. But low-risk does not mean no risk. Here is what it costs and when it makes sense.
Last updated: August 2026
The Short Answer
Not required, but recommended for most Zone X homeowners at $722 per year on average.
- Zone X is outside the SFHA - no federal mandate to purchase flood insurance
- About a quarter of NFIP flood claims come from outside high-risk zones
- At $722 per year on average, the annual cost is a fraction of the average flood claim payout ($50,000+)
Why Zone X Properties Still Flood
Zone X designates areas with a less than 1% annual chance of flooding. That sounds safe, and it usually is. But several factors regularly cause flooding in Zone X properties:
- Flood maps are drawn based on models with margins of error. A property near the SFHA boundary on the Zone X side of the line can face nearly the same physical risk as the Zone AE property next door.
- Localized flooding from overwhelmed storm drains, clogged culverts, or aging municipal infrastructure can impact any property, regardless of flood zone.
- New construction or paving upstream increases runoff volume and speed, raising flood risk in downstream areas that were previously considered safe.
- FIRM maps are not updated in real time. Your Zone X designation may reflect conditions from a study conducted decades ago, before significant changes to the landscape or climate patterns.
From FEMA's claims data: About a quarter of all National Flood Insurance Program claims come from properties outside the Special Flood Hazard Area. This includes Zone X properties.

| State | Zone X avg./yr | Zone AE avg./yr | Zone X Savings |
|---|---|---|---|
| Connecticut | $876 | $1,522 | $646/yr less |
| California | $812 | $1,334 | $522/yr less |
| Arkansas | $828 | $1,117 | $289/yr less |
| Georgia | $646 | $991 | $345/yr less |
| Alabama | $790 | $961 | $171/yr less |
| Colorado | $724 | $1,073 | $349/yr less |
| Arizona | $784 | $1,070 | $286/yr less |
Zone X policies are available through NFIP-authorized insurers. Risk Rating 2.0 replaced the old flat-rate Preferred Risk Policy that used to apply to lower-risk zones with an individualized premium, but Zone X properties still generally pay less than high-risk zones. Private insurers also write Zone X policies and can be more competitive for properties well outside flood-prone areas.
Zone X Claim Payouts by State
Nationally, Zone X properties have filed 682,942 NFIP claims totaling $20.6B in payouts since 1978. The average Zone X claim pays out $30,116, which is roughly 40 to 75 years of annual premiums recovered in a single event.

| State | Zone X claims | Avg claim payout | Avg annual premium |
|---|---|---|---|
| Connecticut | 6,525 | $14,000 | $876 |
| California | 16,729 | $13,000 | $812 |
| Arkansas | 2,746 | $23,000 | $828 |
| Georgia | 8,284 | $17,000 | $646 |
| Alabama | 8,954 | $33,000 | $790 |
| Colorado | 2,687 | $11,000 | $724 |
| Arizona | 1,762 | $13,000 | $784 |
In every state above, a single average claim payout exceeds 14 years of Zone X premiums. Alabama's average Zone X claim ($33,000) would take over 41 years of premiums to equal.
When Zone X Flood Insurance Makes Sense
Your property is near the SFHA boundary
If your home is just inside Zone X on the flood map, physical flood risk may be only marginally lower than your Zone AE neighbors. The line is a model, not a physical barrier.
The property has flooded before
Prior flood history is a strong predictor of future risk. If the property or the surrounding neighborhood has experienced flooding, the flood map may not fully capture that history.
Older drainage infrastructure nearby
Many municipalities operate stormwater systems designed for earlier development densities. As areas build out, localized flooding increases even in nominally low-risk zones.
Lender or HOA recommends it
Some lenders and HOAs request Zone X coverage even when not federally required. Coverage also protects your mortgage investment in the event of a future remap to Zone AE.
When you might reasonably skip it
Well-elevated with no nearby water
If your property sits on high ground far from any river, stream, or coast, and the area has no history of drainage flooding, the risk-to-premium ratio may favor self-insuring.
Large liquid emergency fund
Some homeowners prefer a higher deductible strategy: carry no flood policy and retain $722 per year on average in a dedicated emergency fund. This is a legitimate risk management choice if you can sustain a $50,000+ loss.
How to Get Zone X Flood Insurance
- 1
Find an NFIP-authorized insurance agent
Any licensed property and casualty insurance agent can sell NFIP policies. You do not need to go through a specialist. Your current homeowners insurer likely offers NFIP policies.
- 2
Ask what is driving your Risk Rating 2.0 premium
Under Risk Rating 2.0, FEMA replaced the old flat-rate Preferred Risk Policy with an individualized premium based on distance to water, flood frequency, elevation, and rebuild cost. Ask your agent which factors are driving your specific quote, since two Zone X properties can price very differently.
- 3
Compare at least one private flood insurance quote
Private insurers often price Zone X properties more competitively than the NFIP because they use more granular risk models. Get at least one private quote before purchasing. Confirm your lender accepts private flood insurance if you have a mortgage.
30-day waiting period: Standard NFIP policies take effect 30 days after purchase. Exceptions apply for loan closings and FEMA map revisions. Do not wait until a storm is approaching to purchase coverage.
Could My Zone X Property Be Remapped?
FEMA updates Flood Insurance Rate Maps on a rolling basis. A map revision in your area could reclassify your Zone X property to Zone AE or another SFHA zone, triggering the mandatory flood insurance purchase requirement.
Risk Rating 2.0 eliminated grandfathering, so a Zone X property that gets remapped into an SFHA transitions to a full-risk premium like any other policy, phased in under the 18% annual increase cap rather than jumping all at once. Holding a Zone X policy before the remap still pays off: your coverage is already active, so you avoid the 30-day waiting period a brand-new policy would face right when the map change puts you at risk. This is one of the strongest arguments for maintaining voluntary Zone X coverage proactively.

Frequently Asked Questions
Is flood insurance required in Zone X?
No. Zone X is outside the Special Flood Hazard Area (SFHA), so federal law does not require lenders to mandate flood insurance for Zone X properties with government-backed mortgages. Coverage is voluntary.
How much does flood insurance cost in Zone X?
Zone X flood insurance costs $722 per year on average, across 1,607,297 policies written or renewed nationally in the trailing 12 months under the NFIP. This is the risk-rated premium only. It excludes the Federal Policy Fee, HFIAA Surcharge and Reserve Fund Assessment, which apply to some policies and not others, so an actual bill runs higher. State averages for policies written or renewed in the trailing 12 months include: Connecticut $910/yr, California $838/yr, Arkansas $880/yr, Georgia $668/yr, Alabama $804/yr. Private insurers sometimes offer lower rates for Zone X properties.
Is flood insurance worth it in Zone X?
For most Zone X homeowners, yes. About a quarter of all NFIP flood claims come from properties outside the SFHA. At $722 per year on average, the annual cost is low relative to the average NFIP flood claim, which exceeds $50,000. Coverage is especially valuable if your property is near the SFHA boundary, in a low-lying area, or in a region with aging drainage infrastructure.
What is the difference between Zone X shaded and Zone X unshaded for insurance?
Zone X shaded (also labeled Zone B on older maps) covers moderate-risk areas with a 0.2% to 1% annual chance of flooding. Zone X unshaded (also labeled Zone C) covers areas with less than 0.2% annual chance. Both are outside the SFHA and both have voluntary, lower-cost insurance. Zone X shaded carries slightly higher risk and may have slightly higher premiums.
Can I get flood insurance in Zone X?
Yes. Zone X properties are eligible for NFIP flood insurance through any NFIP-participating insurance agent. Under Risk Rating 2.0, your premium is calculated individually rather than through the flat-rate Preferred Risk Policy that used to apply to lower-risk zones, but Zone X properties still generally receive lower rates than high-risk zones. Private flood insurers also cover Zone X properties.
What happens if my Zone X property is remapped to a high-risk zone?
If FEMA updates the Flood Insurance Rate Map (FIRM) and your property is remapped from Zone X to Zone AE or another SFHA zone, you will become subject to the mandatory flood insurance purchase requirement if you have a federally backed mortgage. Under Risk Rating 2.0, grandfathering was eliminated, so a remapped property transitions to a full-risk premium like any other policy, subject to the 18% annual increase cap. Holding a Zone X policy before the remap still helps: it starts your coverage clock earlier and avoids the 30-day waiting period new policies face after a map change. Monitoring FEMA map changes in your area helps you plan ahead.
