On July 7, 2023 FEMA released the updated Elevation Certificate that supersedes the old version that had a listed expiration date of November 30, 2022. FEMA does not implement a grace period during the transition to the new form so any Elevation Certificates dated and signed on July 7, 2023 or after must use the updated form.
The following memo provides additional information and guidance about the latest release.
