The Coral Gables campus houses 4,500 enrolled students. This group is disproportionately freshmen (89 percent of new freshmen live on campus compared with 39 percent of all degree undergraduates). UM's on-campus housing consists of five residential colleges and one apartment-style housing area available only to undergraduate degree-seeking students. The residential colleges are divided into two dormitory-style residence halls and three suite-style residence halls. The McDonald and Pentland Towers of Hecht Residential College and the Walsh and Rosborough Towers of Stanford Residential College are commonly referred to as the "Freshman Towers", as the single-sex by floor (with shared bathroom facilities) co-ed dormitories generally house new students. Eaton Residential College, which originally housed only women, and the Mahoney/Pearson Residential Colleges have suite-style housing with every two double-occupancy rooms connected by a shared bathroom.
