In addition, a campus of the California State University that maintains student housing facilities open for occupation during school breaks, or on a year-round basis, shall first give priority to current or former foster youth for residence in the housing facilities that are open for uninterrupted year-round occupation, and next give priority to current or former foster youth for housing that is open for occupation during the most days in the calendar year.
