The threat apparently worked. Chartered fraternity chapters - Alpha Tau Omega, Delta Chi, Kappa Sigma, Phi Gamma Delta, Pi Kappa Alpha, Lambda Chi Alpha (closed 1981) and Sigma Chi - began acquiring off-campus lodges that over time were upgraded to or replaced by fraternity houses. Kappa Sigma's Lambda-Omicron chapter was the first chapter to acquire an off-campus lodge, the site of the present-day Off-Campus Bookstore.
