Learn About Elevation Certificates for Property Owners

What Is an Elevation Certificate and Why It Matters

An elevation certificate is an official document that records the elevation of a building in relation to a specific flood level, usually the base flood elevation (BFE) established by the Federal Emergency Management Agency (FEMA). This certificate provides measurable proof of how high a structure sits above ground level and where it sits relative to flood risk zones. The document includes precise survey measurements and is prepared by a licensed surveyor or engineer.

Property owners may need elevation certificates for several practical reasons. If a property is located in or near a flood zone, lenders often require this document before issuing mortgages. Insurance companies use elevation certificates to calculate flood insurance premiums, as properties built higher may face lower rates. Local building departments may require them during construction or renovation projects to verify compliance with building codes. Additionally, if a property owner wants to challenge their flood zone designation, an elevation certificate can provide the technical evidence needed.

The elevation certificate became standardized in its current form through FEMA guidelines, though the specific requirements may vary by location. The document itself is not a government form that must be filed with a federal agency, but rather a professional survey document that property owners keep for their own records and share with relevant parties like lenders, insurers, or local officials.

Understanding what an elevation certificate contains and why various parties request it helps property owners navigate real estate transactions and insurance matters more effectively. The document serves as a neutral, technical record rather than an opinion or determination about a property's actual flood risk or insurability.

Practical Takeaway: If you own property in or near a flood zone, obtaining an elevation certificate may help you understand your property's position relative to flood levels and can support interactions with lenders and insurance companies.

How Elevation Certificates Are Created and What They Include

Creating an elevation certificate requires hiring a licensed surveyor or engineer who has the training and equipment to take precise measurements of a property. The professional will visit the property and determine the elevation of key points, such as the lowest floor of the structure, the grade level, and the finished floor elevation. They compare these measurements to the base flood elevation shown on FEMA flood maps for that location. The surveyor uses specialized tools like theodolites or GPS equipment to ensure accuracy within acceptable tolerances.

A standard elevation certificate includes several important pieces of information. The document shows the property address and description, often with a map indicating its location. It lists the elevation of the lowest floor of the building, the elevation of the grade (ground level) at various points around the structure, and the base flood elevation for that area. The certificate identifies whether mechanical systems, utilities, or other components are located below the lowest floor. It also notes the date of the survey and is signed and sealed by the licensed professional who conducted it.

The format of elevation certificates is fairly standardized because FEMA provides guidelines that most states follow. However, some variations exist in how information is presented or what additional details may be included. A complete certificate typically includes photographs of the property, detailed measurements, and reference information about how the surveyor determined elevations—such as what benchmarks or datums were used as reference points.

The cost of obtaining an elevation certificate varies by location and property complexity. Simple residential properties in areas with straightforward topography may cost less than complex commercial properties or those on unusual terrain. Surveyors may charge between several hundred to several thousand dollars depending on the scope of work. Property owners should contact local surveyors for specific pricing in their area.

Practical Takeaway: When hiring a surveyor, confirm they are licensed in your state and experienced with elevation certificates. Request a detailed explanation of the costs before work begins, and ask about the timeline for completing the survey.

Understanding Flood Zones and Base Flood Elevations

FEMA creates detailed flood maps that divide areas into different zones based on flood risk. The highest-risk areas are typically labeled as Special Flood Hazard Areas (SFHAs), which include the 100-year floodplain and other high-risk zones. Understanding how your property relates to these flood zones helps explain why an elevation certificate matters. The base flood elevation, or BFE, is the height that water is expected to reach during a 100-year flood event, which is a flood that has a 1 percent chance of occurring in any given year. This does not mean it only happens once per century—it could happen in consecutive years or not for 200 years.

Flood maps are updated periodically as communities change, more data becomes available, or after significant flood events. When maps are updated, properties may be reclassified into different risk zones. A property that was previously outside the floodplain might be moved into it, or vice versa. An elevation certificate showing that a building sits well above the base flood elevation can be useful if a property owner believes the flood map classification is incorrect for their specific property.

Properties outside the designated flood zone may still experience flooding from other causes, such as poor drainage, storm surge, or localized heavy rainfall. An elevation certificate only addresses elevation relative to the mapped base flood elevation, not these other flood scenarios. Property owners should understand their local flood history and drainage patterns in addition to official flood zone designations.

FEMA flood maps are available online through the FEMA Map Service Center, and most communities maintain copies at their local planning or building department. You can search by address to determine your property's flood zone. If you have questions about your specific designation, the local floodplain manager—usually employed by the city or county—can explain the maps and how they apply to your property. This official can also discuss whether an elevation certificate might support a request to reconsider your property's classification.

Practical Takeaway: Check your property's flood zone classification using FEMA's online map tool. If you believe the classification is incorrect, contact your local floodplain manager to learn what documentation, such as an elevation certificate, might support a reassessment.

Elevation Certificates and Flood Insurance Requirements

Flood insurance is a distinct type of coverage separate from standard homeowner's insurance. In the United States, the National Flood Insurance Program (NFIP) provides flood coverage in most areas, though some communities have private or state-run programs. If a property is located in a high-risk flood zone and the owner has a federally backed mortgage, flood insurance is typically required. Even if not required, property owners in flood zones often purchase it to protect their investment.

Insurance companies use elevation certificates to determine flood insurance premiums. When a building's lowest floor sits significantly above the base flood elevation, the property may be classified as lower risk, potentially resulting in lower insurance rates. Conversely, if the structure is near or below the base flood elevation, premiums will be higher. Some properties that sit high enough above the BFE may be classified as "elevated" and receive discounts. This is why obtaining an elevation certificate can have direct financial implications for property owners in flood zones.

In some cases, property owners dispute their flood insurance premiums as too high. An elevation certificate may help clarify whether the premium is accurate based on the property's actual elevation. If the certificate shows the building is higher than previously recorded, an insurance company may recalculate the rate. Conversely, if a property is lower than expected, the insurance company may adjust the premium upward. The elevation certificate provides the documented evidence needed for such conversations.

Insurance agents can explain how an elevation certificate might affect your specific policy and costs. They can also provide guidance on whether obtaining one makes financial sense based on your property's location and current insurance status. For properties with significant flood risk, the cost of a surveyor's elevation certificate may be offset by years of lower insurance premiums.

Practical Takeaway: Contact your flood insurance agent or provider to learn whether an elevation certificate could reduce your premiums. Compare the cost of the surveyor's work against the potential annual savings to determine if obtaining one is worthwhile for your situation.

Using Elevation Certificates in Real Estate Transactions

When buying or selling property in or near a flood zone, an elevation certificate may be requested during the lending process. Mortgage lenders require evidence that a building meets certain standards related to flood risk. An elevation certificate demonstrating that the structure sits well above the base flood elevation may simplify the lending process and potentially affect loan terms. Some lenders may require an elevation certificate as a condition of the mortgage, particularly for properties in high-risk areas.
