Standard homeowners insurance generally does not cover flood damage, including coastal flooding and hurricane storm surge. Flood coverage is usually purchased separately. A National Flood Insurance Program (NFIP) policy can cover qualifying direct physical damage from a flood, but limits, deductibles, exclusions, and the policy’s effective date matter.
Does homeowners insurance cover storm surge or coastal flooding?
Usually not. Most homeowners policies exclude flood damage. NFIP guidance defines flood to include excess water on normally dry land, including coastal water overflow and the unusual rise of seawater during a hurricane or coastal storm known as storm surge. Whether a particular loss qualifies depends on the policy wording and the facts about what caused the damage.

“Hurricane damage” is not one coverage category. Wind damage, rain entering through a roof or other opening, and rising floodwater may be treated differently. NFIP describes its flood coverage as applying to water coming from the ground up; water entering from above is not covered as flood damage under that guidance. The homeowners policy may address wind or rain damage, subject to its own exclusions and endorsements. Neither description settles a specific claim.

What does each policy cover?
Homeowners and flood insurance address different risks. The table summarizes general NFIP guidance; it does not guarantee coverage for an individual property or loss. Private flood policies may have different terms.
| Loss or feature | Standard homeowners insurance | NFIP flood insurance |
|---|---|---|
| Coastal flooding and storm surge | Most policies exclude flood damage; exact wording and endorsements matter. | May cover qualifying direct physical flood damage, including coastal overflow and storm surge. |
| Home structure | May cover other insured perils under the policy, but generally not flood damage. | Building coverage can include the structure, foundation, utilities, permanently installed items, and certain detached garages. The publicized maximum homeowner building limit is $250,000. |
| Belongings | Flood-related contents loss is generally excluded with flood damage. | Separate contents coverage is available for qualifying belongings. The publicized maximum homeowner contents limit is $100,000. |
| Deductibles | Check the policy; a separate windstorm deductible may apply. | Building and contents coverage typically have separate deductibles. |
| Temporary housing and extra living costs | Do not assume these costs are covered when flooding displaces you; confirm the policy terms. | NFIP does not cover temporary housing or additional living expenses while the home is repaired. |
| Vehicles and outdoor property | Check the applicable auto or property policy. | Excludes cars and most self-propelled vehicles, as well as outdoor property such as landscaping, fences, pools, decks, and patios. |
| Basement | Coverage depends on the policy and cause of water. | Coverage is limited to specified installed building equipment and powered contents; ordinary belongings kept in basements are restricted. |
NFIP limits and examples are program guidance, not a promise that every item or loss is insured. Read the policy and declarations for the specific home.

How NFIP coverage limits, access, and timing work
Separate building and contents coverage
NFIP public guidance lists maximums of $250,000 for homeowner building coverage and $100,000 for homeowner contents coverage. They are separate coverages, typically with separate deductibles. Consider whether each limit fits the property and belongings; do not treat a program maximum as the amount every policyholder receives after a loss.
Eligibility and mortgage requirements
Homeowners in communities participating in NFIP floodplain management may be eligible for an NFIP policy. Certain properties in Special Flood Hazard Areas with government-backed mortgages are subject to mandatory flood-insurance purchase requirements. Some lenders require coverage for properties outside high-risk zones, too. Requirements depend on the property’s location, community participation, and lender terms. NFIP eligibility guidance explains the general rules.
Waiting period and effective date
NFIP coverage generally begins 30 days after purchase, with exceptions that include certain mortgage transactions, renewal changes, new high-risk map designations, and wildfire-related floods. Confirm the applicable effective date before relying on a newly purchased policy; do not assume it will cover an imminent storm.
Price and flood maps
NFIP premiums are property-specific and depend on factors including location, building characteristics, and selected coverage; a generic coastal premium cannot tell you what a particular address will cost. Coastal V and VE zones are high-risk coastal areas with additional storm-wave hazard. Flood maps help inform purchase requirements, and map designations can change. See NFIP cost guidance and flood-zone guidance.
