Florida Elevation Certificate

What the certificate records

The form has a standard layout that insurers and floodplain managers read the same way across the country. The pieces a buyer should understand:

• Flood zone and base flood elevation (BFE): pulled from the community's Flood Insurance Rate Map. BFE is the height floodwater is expected to reach in a flood with a 1% chance of happening in any year.
• Building diagram number: a code describing the structure, for example slab on grade, a house on piers or stilts, a crawlspace, or a building with an enclosure below the living floor.
• Elevations: the top of the bottom floor, the next higher floor, the lowest horizontal structural member in coastal V zones, the lowest adjacent grade next to the building, and the elevation of machinery such as the A/C condenser.
• Flood openings: the number and size of vents in any enclosure or garage, which let water pass through instead of pushing against walls.
• Photos and the surveyor's seal.

The number that drives most decisions is the gap between the lowest floor and the BFE. A floor several feet above BFE is a very different risk from one that sits below it.

Why it still matters under current flood pricing

FEMA's current method for pricing National Flood Insurance Program policies, Risk Rating 2.0, uses property-specific data and no longer requires an elevation certificate for most policies. Many buyers read that and skip it. That is often a mistake.

Without a certificate, the NFIP estimates the building's elevation from other data. If the house actually sits higher than that estimate, a certificate can lower the premium. If it sits lower, the certificate may not help, and you don't have to submit it. Private flood insurers, which compete with the NFIP in much of Florida, often ask for one and price more aggressively with it.

Lenders require flood insurance on homes in high-risk A and V zones when there is a federally backed mortgage. Outside those zones it is optional for the lender, though Citizens Property Insurance is phasing in a requirement that its policyholders carry flood coverage regardless of zone. Under that schedule, homes with a dwelling value of $400,000 or more needed it from January 1, 2026, and all remaining Citizens homeowners policies follow on January 1, 2027.

Where to find an existing certificate first

Before paying for a new survey, look for one that already exists. A certificate stays valid as long as the building hasn't been changed in a way that affects its elevation or openings.

• Ask the seller. Sellers who carry flood insurance often have one from their agent or from a prior purchase.
• Check the county or city floodplain or building department. Many Florida communities keep certificates on file for buildings constructed or substantially improved in flood zones, since they are part of the permit record. Some post them in an online lookup.
• Ask the seller's insurance agent through the seller, if the seller can't find a copy.
• Check the seller's flood disclosure. Since October 1, 2025, Florida residential sellers must disclose flood insurance claims and federal flood assistance on the property, which tells you whether a past insurer had elevation data.

For newer homes in flood zones, a certificate is commonly required during construction. If the house was built recently and the county has nothing, ask the builder.

Ordering a new one during the inspection period

If nothing exists, order a new certificate from a Florida licensed land surveyor. The process is short:

• Order in the first days of your inspection period. Surveyors book out in busy months, and you need the result in time to get a flood quote and still have your cancellation right.
• Combine it with the boundary survey if you are ordering one anyway. Many survey firms do both and price them together.
• Arrange access. The surveyor needs to see the exterior, the garage and any enclosed area, and to locate flood openings.
• Ask for the current FEMA form. Insurers may reject an outdated version.

The buyer usually pays, since the buyer is the one buying flood insurance. A seller with a house that sits well above BFE has a reason to provide one before listing, and in flood-prone neighborhoods I ask listing agents for it right away.

Reading the result like an insurer

Once the certificate is in hand, send it to two or three insurance agents who quote both NFIP and private flood. Then look at a few things yourself:

• Lowest floor versus BFE: each foot above BFE generally lowers flood risk and premium. Below BFE is a red flag for cost.
• Garage and enclosure: an attached garage at grade is normal, but finished space or a converted garage below BFE can change how the building is rated.
• Machinery elevation: A/C units, water heaters and electrical equipment below BFE add claim risk.
• Coastal V zones: the elevation of the lowest horizontal structural member and whether the enclosure below has breakaway walls carry heavy weight.

A certificate that shows the building sits above BFE in a mapped high-risk zone can also support a request to FEMA to remove the lender's flood insurance requirement, called a Letter of Map Amendment. That decision is FEMA's, not the lender's, and it only works when the ground next to the structure is at or above BFE.

Using the certificate in your purchase decision

The flood quote belongs in your cost of ownership next to homeowners insurance, property tax and HOA fees. I ask buyers to get it before the inspection period ends, for the same reason they get a wind mitigation report: once you're past that deadline, a surprise premium is your problem.

Two more points. An existing NFIP policy can be assumed by the buyer, which can keep a premium that is still phasing up to its full-risk rate under Risk Rating 2.0, so ask the seller whether they have one. And elevation is only part of the picture. Ask about past water in the house, check the drainage around the lot, and look at the street during heavy rain if you can. If you want homes filtered for flood zone before you fall for one, the shortlist can start there.
