If you bought your property instead of building it yourself, there is a good chance an elevation certificate already exists so be sure to check if it does. Ask the seller of your property for the elevation certificate as it may already exist. If you can’t get a hold of it that way, the deed to the property might have one attached to it.  If all that fails, the local floodplain manager is the primary flood loss prevention authority in your area and may have a file for your property on hand. If your house was built in a housing development, the property developer may have an elevation certificate already on hand, particularly in high-risk areas.
