Lake Nona Flood Zones and Flood Insurance: What to Check Before You Buy

The flood map lookup, the insurance rules that apply even outside a flood zone, and what a Florida seller now has to disclose

By David Myers, Broker Associate · NonaOrlandoProperties.com · Last updated October 2026

Lake Nona is inland, so its flood risk comes from heavy rain and high lake and stormwater levels rather than ocean storm surge. Every address has a FEMA flood zone, and you can look it up free on FEMA's map, the City of Orlando's Information Locator or through Orange County's flood zone determination service. Flood insurance is required in a high-risk A zone with a government-backed mortgage, and Citizens requires flood coverage on every policy with wind coverage starting January 1, 2027, in any zone. The City of Orlando's flood program can cut National Flood Insurance Program premiums by up to 20 percent and Orange County's by 25 percent. Florida sellers must disclose known flood damage, flood insurance claims and flood assistance at or before signing the contract.

Lake Nona takes its name from a 587-acre lake and is ringed by others, including Lake Hart, Lake Mary Jane and Lake Whippoorwill. Buyers coming from other states often assume flood is a coastal problem and skip the question.

Checking a house takes a few minutes and a few free tools. Here is how, and what the answer means for your insurance.

Does Lake Nona flood?

Lake Nona is inland, so ocean storm surge is not the risk. Heavy rain is: Orlando averages more than 53 inches a year, and flood risk follows ground elevation, lakes and stormwater systems.

FEMA's maps rate that risk address by address. Lakefront lots, low ground and land near wetlands and drainage ways can be mapped inside high-risk zones. Flood zones follow elevation and water, not neighborhood lines, so two homes in the same Lake Nona neighborhood can sit in different zones.

Being outside a high-risk zone is not a guarantee. FEMA reports that from 2014 to 2024, nearly one-third of National Flood Insurance Program claims came from outside high-risk flood areas.

How do you find a Lake Nona home's flood zone?

Enter the address on FEMA's Flood Map Service Center. Then confirm it with the City of Orlando or Orange County, depending on which one the home is in.

1. Start with the FEMA Flood Map Service Center, which shows the official flood insurance rate map for any address.
2. Check whether the home is in the city with the City of Orlando's Check Your Address map. Large parts of Lake Nona are in the city, but an Orlando mailing address does not prove it.
3. For a city home, use the city's Information Locator. The city also offers elevation certificates through its GIS web app, and its floodplain staff answer questions at floodplain@orlando.gov.
4. For an unincorporated home, submit Orange County's Flood Zone Determination Request Form or call the Stormwater Management Division at 407-836-5612; a technician will tell you whether the property is in a floodplain.

What do the flood zone letters mean?

Zones that start with A or V are FEMA's high-risk Special Flood Hazard Areas, with at least a 1 percent chance of flooding in any year. V zones are coastal, so in Lake Nona the high-risk zones you will see begin with A.

The City of Orlando lists A, AE and AH as its Special Flood Hazard Area zones. A 1 percent annual chance sounds small; FEMA puts it at a 1 in 4 chance of flooding at least once over a 30-year mortgage.

The 500-year floodplain has a 0.2 percent annual chance of flooding and is not a Special Flood Hazard Area. Areas outside both are mapped as moderate-to-low risk.

Do you need flood insurance on a Lake Nona home?

You must carry it if the home is in a high-risk A zone and you have a government-backed mortgage. You will also need it from January 1, 2027 if your homeowners policy is with Citizens and includes wind coverage, in any zone.

Standard homeowners policies do not cover flood. Florida's required seller disclosure form says so in plain words.

Inside a Special Flood Hazard Area, Citizens already requires flood coverage at any value. Condominium unit-owner policies, tenant policies and policies that exclude wind are exempt. Most new flood policies carry a 30-day waiting period, so do not wait for a storm forecast to buy one.

Do Lake Nona homeowners get a flood insurance discount?

Yes, through FEMA's Community Rating System. The City of Orlando is a Class 6 community, which can mean a 20 percent discount; Orange County is Class 5, with a 25 percent discount.

The discount applies to National Flood Insurance Program policies and comes from the local government's floodplain management work, not anything the owner does. Which one applies depends on whether the home is in the city or unincorporated Orange County.

Get a flood quote alongside your homeowners quote during the inspection period, not the week of closing.

What does a Florida seller have to disclose about flooding?

Under section 689.302 of the Florida Statutes, the seller of residential property must give the buyer a flood disclosure at or before the time the sales contract is signed.

The form asks whether the seller knows of any flooding that damaged the property during their ownership, whether they filed a flood insurance claim, including with the National Flood Insurance Program, and whether they received assistance for flood damage, including from FEMA. The 2025 amendment, in effect since October 1, 2025, widened the first question from insurance claims to any known flood damage.

The disclosure covers only the current owner's time in the house. A new-construction home or a recent purchase has a short record, so the flood map and elevation certificate carry more weight there.

What should a Lake Nona buyer check before the inspection period ends?

Check the flood zone, get the elevation certificate if one exists, read the seller's flood disclosure, and price flood insurance with your homeowners policy.

• Flood zone from the FEMA map, confirmed with the city or county
• Elevation certificate, if the home has one on file
• The seller's section 689.302 flood disclosure
• A homeowners quote and a flood quote, even outside an A zone
• Whether your homeowners carrier is Citizens, and what that means after January 1, 2027

What the Neighbors Know

Lakefront and pond-view lots are where the flood map deserves the closest look in Lake Nona, since the zone follows the water's edge and ground elevation rather than the neighborhood boundary.
