The building used in the majority of this movie is at 303 Glenoaks Ave at the corner of Palm Ave in Burbank. I assume the interiors were used. Still has the helipad on top where Sgt. Vickers had his encounter with the unfortunate party-goers. There's a parking garage attached that I assume was also used in the end chase scene. I heard at one time that the final showdown between Psycho Cop and the baseball bat posse happened on Santa Fe Ave in Los Angeles. Not sure where though. Any help is appreciated!
