At Indiana State only one of the nine sororities have a house (Sigma Kappa). The rest of the sororities live in a stairwell in the Lincoln Quadrangles. When talking to all the different sororities, they all say that there is a "brothel" law in Terre Haute.
Here is the link to Time Magazine, an article on Terre Haute, which was Boom City, USA back in the day. This article was written and soon after, the legislation for the Brothel Law in Terre Haute was put into place.

Eventually, Mayor Larrison is convinced my President Rankin to pursue the Brothel Law because the prostitutes were moving into sorority houses, that was when Indiana State stepped in and voted to rid the sororities of their houses, they were to live on campus in the Quadrangles where they could be monitored and they could keep the prostitutes out.
I will do my best once I get back to Terre Haute to ge the legislation codes. I am 90% sure that they are still in place. There is my proof of how the problem got started. Now it is trying to find exactly when it was put into place that might take some digging.
