Does Homeowners Insurance Cover Flooding?

This is one of the most common misunderstandings I see. Having homeowners insurance doesn’t mean every kind of water damage is covered.

The Florida Department of Financial Services puts it plainly: flood isn’t covered under homeowners policies and requires a separate flood insurance policy.

What counts as a flood

The Department of Financial Services describes the typical definition of flood as an overflow of inland or tidal waters, runoff of surface water from any source, or mudflow. In everyday terms, it’s water that rises from outside and comes in: storm surge, a river or canal over its banks, or heavy rain that pools and enters the house.

Water damage versus flood

• Water damage from something sudden inside the home, like a burst pipe, is the kind of loss a homeowners policy can cover, subject to its terms. On older homes that coverage is often limited. See Water Damage, Plumbing, and Older Homes.
• Flood is rising water from outside. That’s what a flood policy is for.
• Sewer or drain backup is its own category. The Department notes that some policies exclude it unless you add it by endorsement.
• Rain coming in during a hurricane after wind opens up the building is part of hurricane coverage under Florida law, not flood.

When a storm causes both wind damage and flooding, two different policies can be involved, each with its own deductible and its own adjuster.

What your policy already tells you

Florida law requires homeowners policies to carry a prominent notice on the declarations page about flood insurance. If you’ve never read yours, it’s worth a look. It’s the state’s way of making sure nobody assumes flood is included.

How a flood policy works

Most flood insurance is written through the National Flood Insurance Program (NFIP). According to FloodSmart, the program’s official site:

• NFIP policies are sold through participating insurance companies and independent agents. The price is the same whichever one you use.
• A homeowner can buy up to $250,000 of building coverage and up to $100,000 of contents coverage.
• A renter can buy up to $100,000 of contents coverage.
• Building and contents are separate coverages. You can have one without the other.

There’s also a private flood market. Private policies can offer different limits and terms. Availability depends on the property and on current markets, so I check both and tell you what I find.

The 30-day wait

FloodSmart says a new NFIP policy takes effect 30 days after you buy it. There are a few exceptions:

• No wait when you buy the policy in connection with a mortgage.
• No wait when you’re changing coverage at renewal.
• A one-day wait when your property has been newly mapped into a high-risk zone, if you buy within 12 months.
• A one-day wait for flooding related to a recent wildfire.

For most people, that means flood insurance has to be in place a month before it’s needed. In Florida, that’s before hurricane season, not when a storm has a name.

Who should think about flood insurance

In Florida, just about everyone. Two situations make it more than a suggestion:

• Your lender requires it. If it does, your lender will tell you, and it will be a condition of the loan.
• Your home insurance company requires it. Some companies require proof of a flood policy for homes in certain flood zones or close to the coast. Citizens Property Insurance requires it for many of its policyholders.

Outside those cases it’s your choice, and a home outside a high-risk zone is usually far cheaper to cover.

A small bonus

Some home insurance companies give a discount on the homeowners policy when you also carry a flood policy. It’s worth asking about. See Home Insurance Discounts and Credits Worth Asking About.

What to have ready for a flood quote

• The property address
• The year built and the type of foundation
• The flood zone, if you know it
• An elevation certificate, if you have one
• Your mortgage company’s requirements, if any
• Whether you want building coverage, contents coverage, or both
