Home Flood Insurance in Houston & Florida: Zone X Is Not 'No Risk'

Why every Houston homeowner should price flood, and how private flood changed the math.

Homeowners excludes flood — always

Rising water, storm surge, and overflow of a body of water are excluded on every homeowners form. Only a flood policy pays.

  • Wind-driven rain through a damaged roof is a homeowners claim
  • Water rising from the street is a flood claim
  • Sewer backup is an endorsement on homeowners

NFIP caps and ACV

$250K building, $100K contents, contents at ACV, no ALE. Above that, you're self-insured.

  • Risk Rating 2.0 prices on elevation, distance to water, and rebuild cost
  • 30-day wait unless at closing

Private flood

Admitted and E&S private flood now competes hard in Zone X and often beats NFIP with better terms.

  • RCV contents, ALE, higher limits
  • Faster effective date
  • Lenders must accept private flood meeting federal criteria

Frequently Asked Questions

I'm in Zone X — do I need it?

Over half of Harvey flood claims were Zone X. At $400–$900/yr for a typical Houston home, yes.

Does flood cover my car?

No; that's comprehensive on your auto policy.

What if I'm in a mapped zone and my lender requires it?

NFIP or private meeting the federal definition. Get an elevation certificate — it can cut the NFIP premium in half.
