What Is a Flood Elevation Certificate?
By JC Pacific Corp Published 2026-09-01 Last professionally reviewed: September 2026
A FEMA Elevation Certificate documents information about a building's location, elevation, flood zone,and construction characteristics. It can support floodplain management, insurance rating,and FEMA map-change requests.
Who prepares an elevation certificate?
A properly authorized land surveyor, engineer, architect, or community official may complete or certify applicable portions, depending on current rulesand state licensing requirements.
What information does it contain?
It may document:
- Propertyand building location
- Flood-zone designation
- Base Flood Elevation
- Building diagram
- Lowest-floor elevation
- Attached-garage elevation
- Machineryand equipment elevation
- Photographs
- Surveyor or official certification
When might a buyer need one?
It may be helpful when:
- The building lies in or near a mapped flood area
- The insurer requests elevation information
- The buyer disputes a flood determination
- A map amendment or revision is being considered
- Local floodplain permits require it
- Existing information is incomplete
Does it remove a property from a flood zone?
No. The certificate provides data. FEMA must approve any applicable map-change request.
