Technically, there’s no expiration date on an Elevation Certificate. However, when they’re so old the information isn’t relevant, then a new one may be required. Such as when a building has been reconstructed/elevated or demolished. Sometimes, information required today didn’t appear on the older style forms, and a new one will be necessary.
Usually, older Elevation Certificates remain useful for knowing what the height of a piece of land is above sea level, unless the landscape has changed.
While an expiration date appears in the upper right corner of Elevation Certificates, you can ignore that date; it’s only relevant to expiration of the blank form. Even then, Federal Emergency Management Agency (FEMA) allows for the continued use of these forms after they’ve expired because a new form isn’t ready; sometimes this may take years.
