Nuance to red-zone restrictions; homes intended for year-round occupation can't be built in them, but other construction, including hotels can. I suspect the issue is that (as Carol has mentioned) around Orient there aren't as many locals attempting to build year-round housing, but that non-residents are being allowed to build/rebuild despite the area being red-zoned whereas locals in the other areas are not.

Sounds like France is allowing money to talk and rich builders to skirt red-zone restrictions. This is of course unfair to the local citizens, especially those who are trying to rebuild family homes.
