What Is Flood Insurance?
By JC Pacific Corp Published 2026-09-01 Last professionally reviewed: September 2026
Flood insurance is separate property coverage designed to help pay for certain direct physical losses caused by a covered flood. It may be available through the federally administered National Flood Insurance Program or through private flood insurers.
How is flood insurance different from homeowners insurance?
Standard homeowners insurance generally excludes flooding. Flood insurance addresses certain flood losses, subject to the policy's definition of flood, coverage limits, deductibles, exclusions,and waiting periods. Flood insurance is not the same as:
- Sewer-backup coverage
- Earthquake insurance
- Landslide insurance
- General homeowners water-damage coverage
- A home warranty
Where can Californians buy flood insurance?
Options may include:
- An NFIP policy sold through an insurance company or agent
- A private flood policy
- Certain excess flood products for losses above primary limits
Not every product is appropriate for every lender or property. Confirm that the lender accepts the proposed coverage.
What should buyers compare?
Compare:
- Building coverage
- Contents coverage
- Separate deductibles
- Coverage limits
- Basement or below-grade limitations
- Replacement-cost versus actual-cash-value provisions
- Temporary-housing coverage, if any
- Waiting periods
- Exclusions
- Lender acceptance
- Claim procedures

Educational information
This content is for general educational purposes and is not insurance, geological, geotechnical, engineering, construction, legal, lending, environmental, financial, or emergency-preparedness advice. Flood mapsand other hazard maps serve specific regulatoryand informational purposesand do not predict whether a particular property will flood, slide, settle, erode, or suffer damage. Insurance coverage, exclusions, premiums, deductibles, limits, waiting periods,and eligibility vary. Consult appropriately licensed professionals regarding a specific property.
Request both NFIP and private options where available, then compare actual coverage rather than premium alone.

A note on these flood-and-natural-hazard guides: These articles provide general, educational information about California flood hazard, flood insurance, landslides, earth movement, soil conditions,and coastal risks for buyers. They are not an insurance policy, a quote, a binder, a coverage determination, a flood determination, an elevation certificate, an inspection, a survey, a geological or geotechnical report, an engineering evaluation, or a guarantee that any property is safe, insurable, or free from flooding, sliding, settling, erosion, or other damage. Flood mapsand other hazard maps describe identified conditions or regulatory zones but do not predict whether a particular property will suffer damage. Professional roles are separate:a real estate professional is not a geologist, engineer, surveyor, insurer, floodplain administrator, or inspector,and Property DNA is only one supporting research service, never a substitute for official flood maps, Natural Hazard Disclosures, insurance quotes, elevation certificates, inspections, surveys, geological or geotechnical investigations, engineering evaluations, public records, or professional advice. Time-sensitive products, eligibility rules, deductibles, limits, waiting periods,maps,and regulations must be reviewed against current official sources at publication time. For a specific property, consult current FEMA, California,and local maps,and resources,and direct underwritingand coverage questions to a California-licensed insurance professional,and geological, geotechnical, engineering,and other technical questions to the appropriately licensed professional.
