Merritt Island Flood Zones and Flood Insurance: What Buyers and Sellers Need to Know in 2026

Does a home on Merritt Island require flood insurance? It depends on the property's FEMA flood zone, not on the fact that it is on an island. Homes in Zone AE must carry flood insurance if there is a federally backed mortgage on them. Homes in Zone X are not federally required to, though plenty of Brevard County owners carry it anyway.

That one distinction can swing your carrying cost by hundreds or thousands of dollars a year. It can also change what a buyer is willing to pay for your house.

And it is the question I see answered wrong most often, because people assume that living on an island in Brevard County automatically means high risk. It does not. I have watched two houses on the same street in 32952 land in different zones because of ground elevation.

I have lived on Merritt Island for ten years, and most of my family lives here too, so I have run this check on my own relatives' purchases as well as my clients'. Here is what actually matters right now.

Flood zones are about elevation, not how close you are to water

FEMA maps Merritt Island and the rest of Brevard County by measured ground elevation and modeled storm surge. Not by how close a property sits to the Indian River or the Banana River. Broadly:

• Zone AE. Inside the 100 year floodplain, with roughly a 1% chance of flooding in any given year. Over a 30 year mortgage that works out to about a 26% chance. Flood insurance is mandatory with a federally backed mortgage, and a Base Flood Elevation applies.
• Zone X, shaded. Moderate risk, inside the 500 year floodplain. No federal requirement, but lenders and insurers still notice.
• Zone X, unshaded. Minimal risk, outside the 500 year floodplain.

You can look up any specific address at the FEMA Flood Map Service Center, and Brevard County's Floodplain Administration maintains its own flood zone information for the county.

Look up the address. Not the neighborhood, not the street, the address. That is the whole point of this section.

The maps are being updated, which matters to you right now

Flood maps are not permanent. FEMA issues preliminary maps, there is a review period, and then they become effective.

Property owners have the right to appeal a proposed change during that window, but only if they know it is happening. Most people find out after the fact, when a premium changes.

So if you are thinking about listing in 32952 or 32953 in the next year, check both the current effective map and the preliminary map for your parcel before you set a price. If you are buying, ask what the preliminary map shows, not just the current one.

That single question is the difference between an informed offer and an expensive surprise.

Florida law now requires sellers to disclose flood history

This changed recently and a lot of people have not caught up.

Under Florida Statute 689.302, sellers of residential property must give the buyer a completed flood disclosure at or before the time the sales contract is signed. That applies to contracts executed on or after October 1, 2024.

The Legislature then expanded it with Senate Bill 948, effective October 1, 2025. Sellers now have to disclose any flooding that damaged the property during their ownership, and any flood assistance they received. That second part got broader, because the word "federal" came out of the statute. State, local and private assistance all count now.

The disclosure also has to tell the buyer plainly that standard homeowners insurance does not cover flood damage.

If you are selling, do not treat this as paperwork to sign at the last minute. Fill it out carefully and honestly. If you are buying, read it, and ask follow up questions about anything left blank.

What actually moves your premium

Zone is the headline, but it is not the whole bill. These are the things that change what you pay:

• Elevation. Where your finished floor sits relative to the Base Flood Elevation. An elevation certificate is what proves it.
• Whether an elevation certificate exists. If one does, get it. If not, factor the cost of having one done.
• Foundation type, and whether there is an enclosure below the elevated floor.
• Coverage amount and deductible, same as any policy.
• Your carrier. The National Flood Insurance Program is not your only option anymore. Private flood carriers write in Florida, and the quotes can differ a lot.

Seller checklist before you list on Merritt Island

• Look up your parcel on both the current effective map and the preliminary map
• Find your elevation certificate, or price out getting one
• Pull your flood insurance history and any claims
• Complete the statutory flood disclosure carefully rather than at the closing table
• Know your number before a buyer's inspector tells you theirs

Buyer checklist before you write an offer

• Look up the flood zone for that exact address, not the subdivision
• Request a flood insurance quote during your inspection period, before financing is locked
• Read the seller's flood disclosure and ask about anything left blank
• Ask whether an elevation certificate exists, and if not, factor the cost of obtaining one
• Check what the preliminary map shows, not just the current one

If the property is canal front or river front, add the seawall, dock and lift to that list. Coverage varies by inspector, so ask your inspection company what is included and how deep it goes, and hire a contractor who specializes in seawalls if it is not covered.

Frequently asked questions

Is all of Merritt Island in a flood zone? No. Technically every property is in some mapped zone, but plenty of Merritt Island sits in Zone X, where flood insurance is optional rather than required. Zone assignment follows ground elevation, so it varies street by street and sometimes lot by lot.

Can I get flood insurance on a Merritt Island home that is not required to have it? Yes, and many owners in Zone X do. Premiums outside the high risk zones are usually much lower, which is exactly why it is worth pricing rather than assuming.

Does a flood zone change automatically raise my premium? Not automatically. If your property gets remapped into a higher risk zone, there are grandfathering provisions and rating rules that can soften the change. Talk to an insurance agent who writes flood in Brevard before assuming the worst.

Where can I look up the flood zone for a specific Merritt Island address? Start with the FEMA Flood Map Service Center and Brevard County's Floodplain Administration. Or send me the address and I will pull it for you.

Flood zone is not a thing to guess about, and it is not a thing to find out about after you are under contract.

Send me an address and I will tell you what zone it is in, what the preliminary map shows, and whether an elevation certificate is on file. Whether you end up working with me or not.
