Elevation Certificate
What is an elevation certificate for flood insurance?
An elevation certificate is a document prepared by a licensed land surveyor or engineer that officially records a building’s elevation relative to the base flood elevation (BFE) in its location. The BFE is FEMA’s estimate of the water level expected to be reached or exceeded during a major flood event, specifically a 1-in-100-year flood. The certificate tells the flood insurance program exactly how much higher or lower a home sits relative to that benchmark.
How does an elevation certificate affect flood insurance premiums?
The difference in elevation between a home and the BFE directly determines the flood insurance premium. For every foot above the BFE the lowest floor sits, premiums drop meaningfully. For every foot below it, they rise steeply. A home sitting two feet above the BFE might pay around $700 per year for flood insurance. The same home sitting one foot below the BFE might pay $3,500 per year or more for comparable coverage. As explained in our flood coverage guide, standard homeowners policies exclude flood damage entirely, making flood-specific premiums a significant cost factor for homes near water.
Which Georgia properties require an elevation certificate?
Georgia sits within FEMA flood zones that span coastal tidal areas near the Golden Isles, riverine floodplains along the Altamaha and Savannah rivers, and urban drainage corridors in metro Atlanta. Many properties near these corridors were remapped during FEMA map modernization cycles and now carry flood zone designations that were not present when the home was built. Elevation certificates are required for flood policies in high-risk Special Flood Hazard Areas. Many insurers also request them for moderate-risk zones to confirm accurate rating. The underwriting calculation for flood insurance relies heavily on the elevation data the certificate provides, which is why an outdated certificate can produce an inaccurate rate.
What information does an elevation certificate capture?
The certificate records not just the lowest floor elevation but also the elevation of any attached garage, crawlspace, or enclosure. For example, a finished basement that sits below the BFE increases the flood risk profile of a structure even when the main living floor is above the benchmark. For example, a raised coastal home with an enclosed ground-floor storage area may carry a higher rate than an otherwise identical home with open lattice below the living space, because enclosed areas at lower elevations affect the rating calculation. Those details feed directly into the insurer’s rating and can produce meaningful premium differences depending on how the structure was built.
When should a homeowner obtain a new elevation certificate?
If a certificate was prepared years ago and the area has since been remapped, the old certificate may not reflect the current zone accurately. The cost of obtaining a new one typically ranges from several hundred to around a thousand dollars, depending on lot complexity. That cost is often recovered within the first year of premium savings when results are favorable. When buying a home in or near a flood zone, requesting a current certificate before closing gives accurate premium information before committing.

A coverage review can confirm whether a property has a current certificate on file, as outlined in our coverage review FAQ.
