Flood insurance, NFIP or private.
Homeowners policies exclude flood. I compare National Flood Insurance Program policies with private flood markets, including excess coverage for homes worth more than NFIP limits.
Quick answer You generally need flood insurance if your home is in a high-risk flood zone with a federally backed loan; elsewhere it isn't usually required, but homeowners policies exclude flood and flooding happens outside high-risk zones too.
- Standard homeowners, condo and renters policies exclude flood damage; flood coverage comes from the NFIP or from private flood insurers.
- Outside high-risk flood zones, flood insurance isn't usually required, but flooding happens there too and premiums there are often lower.
- Flooding can happen outside mapped high-risk zones, including from heavy rain and mudflow after wildfires.
- NFIP flood policies generally take effect 30 days after purchase, with some exceptions such as a loan closing.
- Beyond National Flood Insurance Program (NFIP) policies, private flood markets include excess coverage for homes worth more than NFIP limits.

- Flood zone: from your lender or FEMA’s map, if you know it.
- Elevation certificate: if you have one.
- Foundation: slab, crawlspace, basement or raised.
- Values: building and contents.

Flood insurance, answered
Is flood covered by homeowners insurance?
No. Flood damage is excluded from standard homeowners, condo and renters policies.
How much coverage does the NFIP offer?
Up to $250,000 for a residential building and $100,000 for contents.
How soon does flood insurance start?
NFIP policies generally have a 30-day waiting period, with exceptions such as coverage required for a loan. Private flood waiting periods vary.
Do I need flood insurance outside a high-risk zone?
It isn’t usually required, but flooding happens outside high-risk zones too, and premiums there are often lower.
Do you offer flood insurance outside California?
Yes. Clients across the country send the same quote form. California policies are placed directly; outside California the request is handled together with a partner agency in your state, and the shopping across carriers works the same way. Rules, minimums and markets differ by state — see insurance requirements by state or high-value home insurance by state.
