A substance-free dorm does not allow drugs, drinking or smoking. Usually, if you are caught doing drugs, drinking or smoking in a substance-free dorm, you risk getting kicked out. Another type of dormitory is special-interest housing, which accommodates students who are similar in some way; perhaps music majors or international students will be grouped together.
Most colleges require freshmen students to live in same-gender dorms, while some institutions maintain this requirement regardless of school year. Incoming students will receive this information in their acceptance packets, along with rules about when opposite sexes are allowed to visit each other.
Colleges typically require freshmen or first-year students to live in the same dorms. This gives new students time to adjust to college life. Upperclassmen dorms house sophomores, juniors and seniors. This type of dorm often has fewer restrictions than those for freshmen. Most upperclassmen dorms also allow females and males to live on the same floors.
Sorority sisters or fraternity brothers may opt to live in Greek housing, whether it is on- or off-campus. While this arrangement usually offers more spacious sleeping areas, it does not come with a lot of privacy, due to the amount of constant activities and the nature of belonging to a sorority or fraternity. In addition, Greek housing often offers an in-house laundry room and may sometimes have a cook to prepare daily meals.
