Do I Need Flood Insurance in Houston?

Short answer: if you own or rent in the Houston area, you should at least get a flood quote, even if you're not in a mapped flood zone. Here's why, and how flood coverage works.

Home insurance doesn't cover flood

This surprises many people. A standard homeowners or renters policy in Texas excludes flood damage: rising water from heavy rain, overflowing bayous or creeks, or storm surge. The TDI Home Insurance Guide spells this out. Wind damage from a hurricane may be covered by your home policy, but the water that comes in from the ground up is not.

Why Houston is different

Houston is flat, has heavy clay soils that don't absorb water quickly, and sits in a network of bayous and creeks. Intense rain can overwhelm drainage in neighborhoods far from any river. The Harris County Flood Control District has extensive information on local watersheds and flood history.

Flood maps are a starting point, not a guarantee. FEMA's flood maps show risk zones, but homes outside high-risk zones flood too. FEMA reports that a large share of NFIP flood claims come from properties outside high-risk areas, which is why they encourage everyone to consider coverage (FloodSmart).

When flood insurance is required

If your home is in a high-risk flood zone (zones starting with A or V) and you have a mortgage from a federally regulated or insured lender, your lender will require flood insurance. Outside those zones it's optional, but it's often much more affordable there.

Your options: NFIP and private flood

National Flood Insurance Program (NFIP). Run by FEMA and sold through agents like us. Coverage limits for a home are up to $250,000 for the building and $100,000 for contents. Details are on FloodSmart.gov.

Private flood insurance. Some private carriers offer flood policies that may have higher limits, extra coverages like living expenses, or different pricing. Availability varies by property.

We can quote both and compare them.

The 30-day waiting period

NFIP policies generally don't take effect until 30 days after you buy them. There are exceptions, such as when coverage is required as part of a new mortgage, but you can't count on buying it when a storm is already in the Gulf. FEMA explains this in its waiting period FAQ.

Hurricane season runs June 1 through November 30. The time to buy is before the forecast turns bad.

What flood insurance covers

Building coverage typically includes:

• The structure and foundation
• Electrical and plumbing systems
• Central A/C, furnace and water heater
• Built-in appliances, cabinets and permanently installed flooring

Contents coverage (bought separately) typically includes:

• Furniture, clothing and electronics
• Portable appliances like washers and dryers

Limits to know: NFIP coverage in basements is limited, and it doesn't pay for temporary living expenses. Cars aren't covered by flood insurance; flood damage to a vehicle is handled by comprehensive coverage on your auto policy.

Renters need it too

If you rent, your landlord's flood policy covers the building, not your things. A contents-only flood policy for renters is usually inexpensive and protects your furniture, clothes and electronics.

Wind vs. water after a hurricane

After a hurricane, many Houston homes have both kinds of damage. Wind that tears off shingles and lets rain in through the roof is usually a homeowners (or windstorm) claim. Water that rises from the street and comes in through the doors is a flood claim. If you have both policies, you'll file two claims with two deductibles, and adjusters will look at which damage came from which cause. Having both policies in place means you're not stuck arguing over the line between them.

Keep your declarations pages for both policies somewhere you can reach from your phone, along with your carriers' claim numbers.

How much does it cost?

It depends on your home's specific flood risk, elevation, foundation type, replacement cost and the coverage you choose. Since FEMA's Risk Rating 2.0 pricing, premiums are based on each property's individual risk rather than just its zone. The only way to know your price is to get a quote.

A quick checklist for Houston homeowners

• Look up your address on the FEMA Flood Map Service Center.
• Ask whether your home has flooded before; sellers must disclose known flooding in Texas.
• Get a flood quote with building and contents coverage.
• Buy at least 30 days before you might need it.
• Make a home inventory with photos and keep it in the cloud.
• Confirm your auto policy has comprehensive coverage.
