By 1920, parents were calling for a high school that was primarily college preparatory. So Archbishop Dowling, Ireland's successor, went to all Minneapolis parishes to raise the $200,000 needed to build a new high school on the former King property, adjacent to the existing commercial building. Construction began in May 1922, and within a year, the new DeLaSalle High School building (today known as the "B Building") had opened. Within six years, DeLaSalle was accredited as college preparatory by both the University of Minnesota and the North Central Association of Colleges and Secondary Schools. (More than eight decades later, the school is still accredited by AdvancEd, the successor to North Central.)
