I had first heard about the city of Kennesaw's codes about fraternity and sorority housing from SPSU's housing department when I asked them about this yesterday. After looking through their codes, Greek housing is in fact prohibited in most places throughout the city. While there are a few zones where Greek housing is technically permitted, but I'm not sure whether KSU is in that zone or not.

Beyond that, I have no idea. Zoning and housing codes aren't my forte haha
