University campus The university operates in three campuses in Davao City, both housing several research and academic units. The 4-hectare campus between Roxas Avenue and Jacinto Street is the metropolitan or "downtown" campus as it is situated in the central business district of the city. When it was acquired in 1951, the Jacinto campus was only 3.5 hectares. In 2012, an adjacent 5,000 square meter lot (0.5 hectare) was added to the existing campus. The undergraduate and graduate schools of the university, including the College of Law, which have a combined population of around 8,000 students are housed in this campus. The grade school and high school units are located at a 7.2-hectare campus in the Matina district, a residential area of the city. The Matina campus was originally a 6-hectare lot, and an adjacent 1.2 hectare lot was added to the campus in 2012. In June 2018, the Bangkal campus was opened for its senior high school unit. The senior high school campus features four school buildings and one administration building with 4 stories each.
