Flood insurance explained: what it covers, what it skips, and what it costs

Does your homeowners policy cover a flood? (Usually not.) Here is what flood insurance pays for, what it skips, and what your lender can make you buy.

01

Does homeowners insurance cover flooding?

Generally no. Standard homeowners insurance excludes flood damage, so flood needs its own policy.

A burst pipe is usually a homeowners claim. Water that comes in from outside, such as a river overflowing, heavy rain, or storm surge, is a flood loss, and it’s insured separately through the NFIP or a private flood policy.

Water backing up through a drain or sewer is a gray area. Whether it’s covered depends on the cause and the policy, so ask your homeowners agent whether water backup coverage is available.

02

Do I need flood insurance?

If you have a mortgage and the home is in a high-risk flood zone, your lender will require it. Otherwise it’s your decision, and flood risk varies from one property to the next.

With a mortgage

Federally regulated lenders must require flood insurance in high-risk flood zones. Some lenders also ask for it in moderate- to lower-risk zones, so read your lender’s notice instead of assuming.

Without one

Nothing forces you to buy it, and a standard homeowners policy won’t step in for flood damage. You carry the exposure.

Outside a high-risk zone

About 29% of NFIP claims from 2014 to 2024 came from outside high-risk areas, and FEMA recommends coverage regardless of zone. Your own risk still depends on your property.

Look up your address in FEMA’s Flood Map Service Center or use FloodSmart’s flood risk tool.

03

How does a flood insurance requirement from a lender work?

A regulated lender must require flood insurance when a loan is secured by a building in a special flood hazard area in a community that participates in the NFIP. The amount must be at least the lesser of the loan balance, the NFIP maximum for the building, or its insurable value.

Private policies

A lender must accept a private policy that meets the federal definition of private flood insurance. A policy that states “This policy meets the definition of private flood insurance contained in 42 U.S.C. 4012a(b)(7) and the corresponding regulation” can be accepted without further review. A lender may also accept a policy that falls short of the definition if it provides the required coverage, comes from a state-approved insurer, covers borrower and lender, and protects the loan.

If coverage lapses

If a lender finds your coverage inadequate or expired, it must notify you in writing and give you 45 days to fix it. After that it buys a policy for you and charges you. Once you show proof of coverage, it cancels its policy and refunds overlapping premiums.

What to do

Ask the lender for the requirement in writing, and ask whether it will accept a private policy. Then send us the notice along with any policy you’re considering, and we’ll compare them.

Lender rules summarized from the FDIC’s Flood Disaster Protection Act examination manual and the OCC’s private flood insurance final rule. They apply to federally regulated lenders, and your lender’s own policy controls what it accepts.

04

What has to happen before closing on a home with a flood requirement?

You need a flood policy in place by closing, in an amount that meets the lender’s requirement and of a type the lender accepts.

1

Get the requirement in writing

Ask the lender for the coverage amount, the policy types it accepts, and how the mortgagee should be listed.

2

Get quotes

Start online or call us. If a private policy looks better than NFIP, confirm the lender will take it before you commit.

3

Buy with the date in mind

NFIP has no waiting period for coverage tied to buying a mortgage. Private waiting periods vary. Get the effective date in writing.

4

Send proof to the lender

Give your lender or closing attorney proof of coverage, and keep a copy for yourself.

05

What does flood insurance cover, and what doesn’t it?

NFIP policies cover the building, up to $250,000 for a home, and belongings, up to $100,000, with several notable exclusions. Private policies vary, so read the actual terms.

What NFIP policies are built to cover

  • The home itself. Building coverage up to $250,000 for a residential building.
  • Your belongings. Contents coverage up to $100,000, paid at actual cash value, not original cost.
  • Renters. Contents-only coverage, up to $100,000.
  • Businesses. Building and contents, up to $500,000 each.

What NFIP policies do not cover

  • Belongings kept in a basement
  • Temporary housing and other additional living expenses
  • Business interruption losses
  • Cars and most self-propelled vehicles, including their parts
  • Currency, precious metals, stock certificates, and other valuable papers
  • Exterior property such as landscaping, decks, pools, and fences
  • Earth movement, and mold or mildew damage that could have been avoided

Based on FEMA’s FloodSmart summaries of NFIP coverage. Private policies differ, and every policy’s actual terms control.

The NFIP maximum is a cap, not a rebuild estimate

If rebuilding your home would cost more than $250,000, an NFIP policy alone may leave a gap. Private policies may offer higher limits, so ask about both.

06

What is the difference between NFIP and private flood insurance?

The NFIP is the federal program, with standardized coverage and fixed maximums. Private flood policies come from private insurers that set their own limits, terms, and eligibility. Neither is better in every case.

How much does flood insurance cost?

It depends on the property, the coverage limits, the deductible, and the insurer. We don’t publish an average, because an average tells you very little about your address.

For the NFIP, FEMA’s Risk Rating 2.0 prices each policy using property characteristics such as distance to a water source, elevation, first-floor height, and the cost to rebuild. You can choose different deductibles for building and contents, and that changes the rate too.

NFIP rates are the same across participating insurers and agents. Private insurers set their own prices, so two private quotes for one address can differ in limits, deductibles, waiting periods, and benefits as well as premium.

A lower premium isn’t automatically a better buy. Compare what each policy would actually pay for.

Ways to bring an NFIP rate down

Submit an elevation certificate. It’s optional now, and it may lower your rate.
Elevate the building, add flood openings, or elevate equipment. FEMA credits each.
Adjust your deductibles within NFIP guidelines.

For most NFIP policyholders, annual premium increases are capped at 18%.

08

When does flood insurance take effect?

NFIP coverage generally begins 30 days after purchase. There’s no wait when coverage is tied to a mortgage transaction, and a few other exceptions apply. Private flood waiting periods vary by insurer.

0Day 0You buy the policy
30Day 30NFIP coverage generally begins
Mortgage transactions No waitNo waiting period when you buy, increase, extend, or renew a mortgage.
Changing coverage at renewal No waitNo waiting period when you change your coverage as part of a renewal.
New high-risk designation 1 dayOne-day wait if the property was newly designated as high risk within the past 12 months.
Wildfire on federal land 1 dayOne-day wait if flooding is caused or worsened by a wildfire on federal land, within 60 days of containment.

Waiting periods shown are the NFIP’s, per FEMA’s FloodSmart. Private flood waiting periods vary by insurer, so confirm the effective date before you buy.

That 30 days is why timing matters: a policy bought once a storm is forecast generally won’t cover that storm. If you want coverage, buy it well before flood season or a storm.

09

How do I file a flood insurance claim?

Report it to your insurer or agent right away, document everything before you clean up, and send your paperwork within 60 days of the flood.

1

Report it right away

Contact your insurer or agent with your policy number as soon as you can. Don’t go back into the building until it’s safe.

2

Document before you clean

Photograph and video the damage, including water lines. List damaged belongings with descriptions, age, value, and serial numbers.

3

Keep the evidence

Separate damaged from undamaged items, keep samples of carpet or flooring, and don’t throw damaged property away unless it’s a health hazard or local law requires it.

4

Meet the adjuster

Ask to see the adjuster’s Flood Control Number card and photo ID. You can ask for an advance payment.

5

Send your paperwork

Submit the required documentation within 60 days of the flood. Check the estimate, and ask for more if you find damage it missed.

6

Appeal if you need to

If a claim is denied, you have 60 days from the date of the letter to appeal.

Based on FEMA’s NFIP claims checklist for policyholders. Private policies set their own claim procedures, so follow your policy’s instructions.

10

What mistakes do people make with flood insurance?

Assuming homeowners covers it

Standard homeowners policies generally exclude flood. Check before a storm, not after.

Buying when a storm is forecast

With a 30-day NFIP waiting period, a policy bought after a storm is forecast generally won’t cover it.

Stopping at the lender’s minimum

The minimum is tied to your loan balance and the NFIP cap. It isn’t an estimate of what it costs to rebuild.

Storing belongings in the basement

NFIP coverage doesn’t include belongings kept in a basement. Move what matters, or ask about policies that do.

Buying private flood without asking the lender

Lenders must accept policies that meet the federal definition, but one that falls short is at the lender’s discretion. Ask first.

Letting coverage lapse

If a required policy lapses, the lender can buy one for you and bill you for it.

11

What happens if the NFIP’s authorization lapses?

The NFIP can only issue policies while Congress has the program authorized. During a lapse it can’t issue new policies or renew existing ones. Policies already in force stay in effect through their term, and private flood insurance isn’t affected.

Existing policies

They remain in force through their expiration date plus the standard 30-day grace period. Claims continue to be paid as long as FEMA has funds available.

New and renewal policies

No new NFIP policies or renewals can be issued until Congress reauthorizes the program. Private flood policies can still be written.

Closings

Lenders handle lapses differently, and some federal lending requirements are relaxed during one. Ask your lender how it will treat your closing. A seller’s NFIP policy may be assignable to a buyer.

Authorization has been extended in short stretches.

Congress has repeatedly extended the NFIP in short-term measures, often attached to funding bills, so check the current authorization status with an agent before you plan a purchase around a specific date.

12

What should I ask before I buy a flood policy?

  • Building and contents limits, and whether both are included.
  • Deductibles, and how they apply to building and contents.
  • Basement restrictions and how belongings are treated.
  • Replacement cost versus actual cash value, where applicable.
  • Additional living expenses or business interruption, if offered.
  • Effective date, waiting period, exclusions, and whether your lender accepts the policy.
13

What else do people ask about flood insurance?

What is a special flood hazard area?

It is the area FEMA maps as having at least a 1% chance of flooding in any given year, shown on flood maps with zones that start with A or V. Federally regulated lenders must require flood insurance there.

Can renters buy flood insurance?

Yes. A renter can buy NFIP contents coverage, up to $100,000, for their belongings. It doesn’t cover the building, which is the owner’s to insure.

Can I buy it if I’m not in a flood zone?

In general, yes, if your community participates in the NFIP. The NFIP sells to properties in any risk zone, and private insurers set their own eligibility. Risk is lower outside high-risk areas, not gone.

How long does a policy last?

NFIP policies are written for one year and renew annually. Renewal is when a rate change takes effect, and the 18% cap on increases applies to most policies.
