Contact your university's housing department and ask about the steps needed to obtain on-campus housing. Be sure to inquire about application deadlines for residence halls, as some dorms -- particularly those housing freshmen -- have limited space.
Research the residence halls. Check the school's housing website, as some colleges provide dorm information online. Note application deadlines, occupation prerequisites (some schools allow only freshmen to live in certain dorms; upperclassmen in others), roommate requirements, dorm type (co-ed, single-gender, athlete- or honor student-only), room type (single, double or suite), amenities, activities and proximity to your classes or job.
Make a list of the pros and cons for each dorm. For example, depending on your particular needs, the pros for a particular dorm might entail quiet study hours, wireless Internet access, cable television, air conditioning, computer labs, nearby dining halls and residence hall activities. The cons might include long distances from classes, a loud environment, no air conditioning, no cable television or no elevator in high-rise dorms.
Narrow your list to about two or three residence halls and choose the one that best meets your needs.
Apply for housing. The method for application submissions will vary depending on your particular school. Some schools allow students to apply online, while others require students to submit applications via postal mail. The housing office will contact you with a decision within the time frame listed on their informational material.
