An elevation certificate documents your building's height relative to the Base Flood Elevation. The right certificate can dramatically reduce your flood insurance premium — or help remove you from the flood zone entirely.
If you own property in a Florida flood zone, your elevation certificate is one of the most financially significant documents associated with your home. It can mean the difference between a $2,000 flood insurance premium and a $12,000 one — for the same house.
Here's what an elevation certificate is, why it matters, and what you can do with it.
What Is an Elevation Certificate?
An elevation certificate (EC) is a FEMA-standardized document that records the elevation of a building relative to the Base Flood Elevation (BFE) — the flood elevation that has a 1% chance of being equaled or exceeded in any given year (also called the 100-year flood level).
The certificate is completed by a licensed land surveyor or engineer and documents: - The lowest floor elevation of the structure - The elevation of attached garages and enclosures - The flood zone and BFE at the property - Characteristics of the structure relevant to flood insurance rating
How It Affects Your Flood Insurance Premium
Your flood insurance premium under the NFIP is determined in large part by how your lowest floor elevation compares to the BFE.
- At or above BFE: Lower premiums. The higher above BFE, the lower the premium.
- Below BFE: Higher premiums — often dramatically higher. A structure one foot below BFE can cost several times more to insure than the same structure one foot above.
Many Florida homeowners are paying flood insurance premiums based on old or inaccurate elevation data. If your property was surveyed years ago — before a flood map update, before a recent renovation, or before better survey technology was available — there's a real chance your EC doesn't reflect your actual elevation accurately.
Getting an updated EC can result in significant premium reductions.
Using an Elevation Certificate to Challenge Your Flood Zone
If your property is shown on FEMA's flood maps as being in a high-risk flood zone but your actual elevation is above the BFE, you may be eligible for a Letter of Map Amendment (LOMA) — an official FEMA determination that removes your property from the Special Flood Hazard Area.
A successful LOMA means: - You may no longer be required to carry flood insurance (though it's often still advisable) - Your property value is positively affected - Future buyers aren't burdened by mandatory flood insurance requirements
The LOMA process requires a current, accurate elevation certificate completed by a licensed surveyor.

Expect to pay $300–$700 for an elevation certificate from a licensed Florida surveyor. For properties where the premium savings are substantial — and in many Tampa Bay flood zones, they are — the EC pays for itself quickly.
The Bottom Line
If you're in a Florida flood zone and you don't have a current elevation certificate, or if yours is more than a few years old, it's worth getting a new one. The potential premium savings are significant, and the data on your EC may also support a LOMA that removes the flood zone designation entirely.
