Tonythepilot, correct. This was not a building permit. It was issued under emergency conditions as part of the DPI. You can see that the Permit Number field is crossed out and DP written in.

To clarify, under the terms of the new version of the PPRN, if they are incorporated as expected, only REbuilding will be allowed. That is, buildings that existed prior to Irma will be allowed to be rebuilt and they can be rebuilt with modifications that will allow them to meet the requirements of the PPRN. For example, the wooden units at Club Orient would be rebuilt in concrete. For residences in Sandy Ground it may mean that people who would not otherwise be allowed to rebuild should be allowed to do so. The government recognizes that it is important to allow people to rebuild their homes but will require them to be safer and also recognizes the need for resorts such as Club Orient.
