What Is an Elevation Certificate? A Homeowner's Guide

Updated for 2026 · 7 min read · Survey Types

What an Elevation Certificate Is

An elevation certificate is an official FEMA form completed by a licensed surveyor, engineer, or architect that documents the elevation of a building relative to the expected flood level in that area. It records how high your lowest floor sits, where your property is on the FEMA flood map, and specific physical characteristics of the building that affect flood risk.

Insurance companies use elevation certificates to calculate accurate flood insurance premiums under the National Flood Insurance Program (NFIP). Without one, insurers assign a default rate that is often much higher than what the property actually warrants based on its elevation.

For Florida homeowners, the elevation certificate is one of the most practical survey-related documents you will encounter. Florida has more properties in FEMA-designated Special Flood Hazard Areas than any other state, which means a large portion of the state's property owners either have or need an elevation certificate.

Why Flood Insurance Cares About Elevation

Flood insurance rates under the NFIP are not the same for every house. They depend heavily on how your home's lowest floor compares to the Base Flood Elevation (BFE), which is the elevation at which FEMA predicts a 1 percent annual chance of flooding.

Here is why that matters in practice:

  • If your lowest floor is 1 foot above the BFE, your flood insurance premium will be significantly lower than if you were at or below the BFE
  • If your lowest floor is 2 feet or more above the BFE, premiums can drop dramatically, sometimes by hundreds or thousands of dollars per year
  • If your lowest floor is below the BFE, you are in a high-risk situation and your premiums will reflect that

The elevation certificate captures your building's exact elevation so the insurer can apply the correct rate rather than guessing or using a conservative default.

FEMA Flood Zones Explained

FEMA maps flood risk across the country using Flood Insurance Rate Maps (FIRMs). These maps divide land into flood zones, and your flood zone determines whether you need flood insurance and how much it might cost.

Flood ZoneRisk LevelInsurance Required?
Zone AE, A, AH, AOHigh risk (Special Flood Hazard Area)Yes, with federally backed mortgage
Zone VE, VHigh risk, coastal wave actionYes, with federally backed mortgage
Zone X (shaded)Moderate riskNo requirement, but available
Zone X (unshaded)Low riskNo requirement, but available

Zone AE is the most common high-risk designation in Florida. It appears along rivers, lakes, coastal areas, and many inland areas. Zone VE applies to coastal properties where wave action is expected during a major storm, particularly along the Gulf and Atlantic coasts.

Florida coastal counties including Pinellas, Lee, Collier, Broward, Miami-Dade, and Volusia have extensive flood zone coverage. Inland counties including Polk, Alachua, and Hillsborough also contain significant mapped flood areas due to lakes, rivers, and low-lying terrain.

How the Base Flood Elevation Works

The Base Flood Elevation is a specific elevation number assigned by FEMA to areas in Special Flood Hazard Zones. It represents the water surface elevation that has a 1 percent chance of being equaled or exceeded in any given year, commonly called the 100-year flood.

For example, if FEMA assigns a BFE of 12 feet to your area, that means the 100-year flood event is expected to reach an elevation of 12 feet above the National Geodetic Vertical Datum (NGVD) or the North American Vertical Datum (NAVD88), the two reference systems used on Florida flood maps.

Your elevation certificate captures your lowest adjacent grade, lowest floor, and lowest opening elevations and compares them to the BFE. The difference, called the freeboard, is what drives the insurance rate calculation.

What the Elevation Certificate Form Contains

The current FEMA elevation certificate form has several sections. The ones property owners care about most:

  • Section A: Property information including address, legal description, and flood zone designation from the FIRM
  • Section B: The specific FEMA Flood Insurance Rate Map panel number, edition date, and BFE from the map
  • Section C: Building elevation information, the actual measurements of your home's lowest floor and other key elevations, filled out by the licensed surveyor
  • Section D: The surveyor's signature, license number, seal, and certification
  • Section E: Building characteristics that affect flood risk, including foundation type, enclosures, and openings

Section C is the section that matters most for flood insurance calculations. The numbers in Section C are what your insurer uses to determine whether your building is above, at, or below the BFE and by how much.

Who Needs an Elevation Certificate

You likely need an elevation certificate if any of these apply:

  • Your property is in FEMA Zone AE, A, AH, AO, VE, or V
  • Your mortgage lender requires flood insurance as a condition of the loan
  • You are purchasing or renewing an NFIP flood insurance policy and want to ensure you are getting the right rate
  • You are applying for a Letter of Map Amendment (LOMA) to remove your property from the flood zone
  • You are constructing a new building in a flood zone and need to demonstrate compliance with local floodplain management regulations
  • You want to dispute your current flood insurance premium and believe your elevation warrants a lower rate

Even if you are not required to get one, an elevation certificate can be worth the cost if it reduces your annual flood insurance premium. Many Florida homeowners are paying more than necessary because their insurer lacks accurate elevation data.

How to Get an Elevation Certificate in Florida

To get an elevation certificate, you hire a licensed Professional Surveyor and Mapper (PSM). The process works like this:

  1. You contact a licensed surveyor and provide the property address
  2. The surveyor visits the property, measures the relevant elevations using survey-grade equipment, and researches the applicable FEMA flood map panel
  3. The surveyor completes the FEMA elevation certificate form, signs and seals it, and delivers it to you usually within one to two weeks
  4. You provide the certificate to your insurance agent, who uses it to recalculate your premium

Before ordering, check with your county's floodplain administrator. Some Florida counties maintain elevation certificates for properties in their jurisdiction, particularly for homes built after flood regulations were adopted. If a certificate already exists for your property, you may be able to get it at no cost or a reduced cost through the county.

What It Costs

A flood elevation certificate in Florida typically costs $150 to $400 for a standard single-family residential property. Factors that can push costs higher include:

  • Rural location or difficult site access
  • Complex foundation type or multiple structures on the same parcel
  • Areas where benchmarks are distant and the surveyor must establish a local elevation reference

The investment frequently pays for itself quickly. A Florida homeowner paying $2,000 per year in flood insurance who discovers their floor is 2 feet above the BFE might see their annual premium drop to $500 or less, meaning the certificate pays for itself within the first policy year.

Florida-Specific Considerations

Florida's flat terrain and proximity to water make flood zone issues particularly widespread. Points specific to Florida property owners:

  • FEMA's Risk Rating 2.0, the updated pricing methodology, changed how NFIP premiums are calculated starting in 2022. Under Risk Rating 2.0, elevation certificates are still useful for rate documentation and LOMA applications, but the rating algorithm also incorporates additional property-specific data beyond the certificate alone.
  • Florida law requires sellers to disclose known flood zone status and flood insurance claims history. An elevation certificate is a useful due diligence document when buying a Florida property in or near a flood zone.
  • Many Florida communities participate in the NFIP's Community Rating System (CRS), which gives premium discounts to properties in participating communities. Check whether your city or county participates, as this affects the total discount available on NFIP policies.

Find licensed surveyors in your Florida county using the directory to get quotes and connect with professionals who handle elevation certificates regularly.

Frequently Asked Questions

Is an elevation certificate required in Florida?

An elevation certificate is not required by Florida law for all properties, but it is required by the National Flood Insurance Program when you want to purchase or renew flood insurance on a property in a Special Flood Hazard Area. Many Florida mortgage lenders also require one when the property sits in a mapped flood zone.

How long is an elevation certificate valid?

FEMA does not set a formal expiration date on elevation certificates, but insurers and lenders may require a new one if significant changes have been made to the structure or if a new Flood Insurance Rate Map has been issued for your area. Certificates completed after 2015 use the current FEMA form and are generally accepted by insurers. If your certificate is older, contact your insurance agent to confirm it is still acceptable.

Can I get a lower flood insurance rate with an elevation certificate?

Yes, often significantly lower. If your lowest finished floor is above the base flood elevation, your flood insurance premium drops considerably. Many Florida homeowners discover after getting an elevation certificate that they were overpaying for flood insurance because their insurer had been using a less favorable default rate. Even paying $200 to $400 for the certificate can pay for itself many times over in annual premium savings.

Who can complete an elevation certificate in Florida?

Only a licensed Professional Surveyor and Mapper (PSM), a registered engineer, or a registered architect can complete an elevation certificate in Florida. FEMA's form requires the professional's license number and signature. Do not accept a certificate completed by anyone who is not licensed in one of these categories.

What is the difference between Zone AE and Zone X on the flood map?

Zone AE is a Special Flood Hazard Area with a 1 percent annual chance of flooding (the 100-year flood). Properties in Zone AE with a federally backed mortgage are required to carry flood insurance. Zone X is the moderate to low risk zone. Properties in Zone X are not required to carry flood insurance, though it is still available and often advisable in Florida given the state's vulnerability to storm surge and heavy rainfall.
