Quick note for homeowners in flood-risk areas
Flood is the most expensive natural disaster in Texas — and it's never covered by standard home insurance. Hurricane Harvey alone caused over $125 billion in damage, much of it to homes outside FEMA flood zones.
Flood insurance is a standalone policy that covers damage to your home and belongings from rising water — heavy rain, storm surge, overflowing rivers, or coastal flooding. It is never included in standard Texas homeowners insurance, regardless of carrier or policy level.
Texas homeowners can buy flood coverage through two channels: the federally-backed National Flood Insurance Program (NFIP) administered by FEMA, or private flood insurance carriers. NFIP is the default for most homeowners; private flood is often cheaper and offers higher coverage limits but isn't available everywhere.
Federal law requires flood insurance if your home is in a FEMA-designated Special Flood Hazard Area (SFHA) and you have a federally-backed mortgage. Outside flood zones, it's optional — but Hurricane Harvey demonstrated that 'outside the flood zone' doesn't mean 'safe from flooding.'
Pays to repair or rebuild your home's structure (foundation, walls, electrical, plumbing, HVAC) up to NFIP limits of $250,000 or higher with private carriers.
Covers your personal belongings damaged by flood. NFIP limit is $100,000; private carriers often offer higher limits.
Specifically called out because flood damage to these systems is what makes flood claims so expensive — typically the largest dollar component of any flood claim.
Texas flood insurance costs vary dramatically by ZIP code and flood zone. Homes in low-risk zones can pay as little as $32/month for basic NFIP coverage. Homes in high-risk Special Flood Hazard Areas (SFHA) can pay $200–$500+/month depending on elevation and construction type.
Private flood insurance is often 20–40% cheaper than NFIP for the same coverage and offers higher limits — but availability varies by ZIP code. Always compare both.
| Scenario | Typical Cost | Notes |
|---|---|---|
| Low-risk zone (Zone X), $250k home | $32–$58/mo | Basic NFIP coverage. Private flood often cheaper. |
| Moderate-risk zone (Zone X shaded) | $58–$98/mo | Outside SFHA but elevated risk. |
| High-risk zone (Zone A or AE) | $148–$285/mo | Required if federally-backed mortgage. |
| Coastal high-risk (Zone V) | $385–$685/mo | Highest-risk coastal Texas zones. |
Texas leads the US in flood damage by a significant margin — driven by hurricanes (Houston, Galveston, Corpus Christi), flash floods (Hill Country, San Antonio), tropical storms (statewide), and extreme rainfall events that overwhelm urban drainage. Hurricane Harvey alone caused over $125 billion in damage in 2017.
FEMA's flood zone maps are out of date in much of Texas — they don't reflect recent climate patterns, urban development that increases runoff, or changes to natural drainage. Studies after Hurricane Harvey found that 70% of flooded Houston-area homes were outside the FEMA-designated flood zone.
This is why many Texas homeowners — even those not required to carry flood insurance — choose to buy a basic policy. At $32–$58/month for low-risk-zone coverage, it's a small premium for protection against the most expensive natural disaster in the state.
Documenting that your home is elevated above the base flood elevation can dramatically reduce NFIP premiums in high-risk zones.
If your Texas community participates in the CRS program, all NFIP policyholders receive a discount based on the community's rating.
Homes built after FEMA's first flood maps for your area (post-FIRM) typically receive lower rates than older construction.
Required by federal law if you have a federally-backed mortgage. Even without a mortgage requirement, the risk is substantial.
70% of Hurricane Harvey flood damage was outside FEMA zones. At $32–$58/month, low-risk-zone coverage is a small premium for substantial protection.
Flood risk varies by topography. Hill Country flash flood risk is real even at higher elevations. Worth getting a quote even if you don't ultimately buy.

David, 47, Houston (Harvey-area)
Home was in Zone X (outside FEMA flood zone) — chose not to buy flood coverage. Hurricane Harvey flooded his home with 4 feet of water; out-of-pocket repair was $87,000. Now carries NFIP coverage at $48/month.
Sandra, 39, Galveston
Coastal property in Zone AE. NFIP quoted her $385/month; private flood carrier matched coverage limits at $245/month with higher loss-of-use coverage included.
Default option for most Texas homeowners, especially in high-risk zones. Required for federally-backed mortgages in SFHA.
Often cheaper than NFIP with higher coverage limits and includes loss-of-use coverage that NFIP doesn't offer.
Higher coverage limits than NFIP's $250k cap — important for higher-value Texas properties.
It never does. Discovering this after a flood is catastrophically expensive. Always confirm flood is a separate policy.
NFIP has a 30-day waiting period. Buying when a hurricane is in the Gulf doesn't help — the policy won't be in force.
Private flood is often 20–40% cheaper with higher limits and better coverage features. Always get both quotes.
Documenting your home's elevation above base flood elevation can cut NFIP premiums by 30–45% in high-risk zones.
Private flood carriers are often 20–40% cheaper for the same coverage. Always quote both.
Raising the flood deductible from $1,000 to $5,000 typically reduces premiums 15–25% if you have savings to cover the gap.
