True or False: The code can require changes in the designated occupancy of a structure for which a lawful permit has already been issued.

The statement is false because once a lawful permit has been issued for a specific designated occupancy of a structure, it means that the project has already been evaluated and approved under the applicable codes at that time. Changes in the occupancy classification typically require a new review process, as different occupancies can have vastly different requirements regarding safety, structural integrity, and accessibility. While it is possible that a code might be changed after a permit is issued, those changes do not retroactively alter the occupancy designation of that specific project. Therefore, the existing permit remains valid for the approved purpose, and the code itself does not have the power to change the designated occupancy once it has received that approval.
