The actual house depicted as the Delta House was originally a residence in Eugene, the Dr. A.W. Patterson House. Around 1959, it was acquired by the Psi Deuteron chapter of Phi Sigma Kappa fraternity and was their chapter house until 1967, when the chapter was closed due to low membership. The house was sold and slid into disrepair, with the spacious porch removed and the lawn graveled over. At the time of the shooting, the Phi Kappa Psi and Sigma Nu fraternity houses sat next to the old Phi Sigma Kappa house. The interior of the Phi Kappa Psi house and the Sigma Nu house were used for many of the interior scenes, but the individual rooms were filmed on a soundstage. The Patterson house was demolished in 1986. The site is now occupied by Northwest Christian University's school of Education and Counseling. A large boulder placed to the west of the parking entrance displays a bronze plaque commemorating the Delta House location. The parade scene takes place in downtown Cottage Grove, Oregon on Main Street.
