The inside of that home looks like a standard flood damage tear out. People sometimes confuse Red DCert tags with a building being condemned but it is not actually the same thing. I didn’t notice any DCert tags or Condemnation Notices on the doors, which ARE required for EVERY entryway into a building that has been inspected by the state after a disaster (so people don’t enter unsafe buildings unaware of the danger). Haven’t worked with fema though so I’m not sure of their process or what tags or marking they use, but all I noticed was a “No Smoking” sign.
