Penn State actually admits that there is no Brothel Law online! Found this
here:
"Myth: There are no sorority houses at Penn State because of an old Pennsylvania law that defined a dwelling that housed a certain number of unrelated women as a brothel.
Fact: Sorority houses did exist on the University Park campus, and there is no such state law nor any University prohibition against sorority houses per se. The first sorority house on campus was Stone House (a former faculty residence), which in 1928 became home to a women’s social club, Nita-Nee, which became Kappa Alpha Theta in 1930 and occupied the house until 1949. Other sororities also had campus houses but, like KAT, moved out of these aging structures soon after World War II and into newly available suites in residence halls. The sororities rented the suites from the University—as they continue to do today. The advantages of residence hall suites and the high cost of private housing in the post-war era discouraged off-campus sorority houses, although the borough of State College, in its zoning laws, makes no distinction between sorority and fraternity houses."
