Hey guys, I'm so excited to be classmates with you this fall. Congratulations on getting accepted to USC!
About housing: the school will send you a housing booklet along with information about vaccination requirements and parking. There is an application inside the booklet which you'll have to fill out and mail in. Then they'll send you a receipt card that they've received it. I was told that you can apply for University Park housing or Seaver housing, but not both. So I just signed up for Seaver.
If you don't like the idea of living in a dorm and would like more privacy, there are several university-owned apartments in the area, which are detailed in the housing booklet. They tend to be pricey, so I would go for privately-owned apartments in Alhambra or Monterey Park, which are only about a 10- to 15-min drive away.
If you are interested in living with roommates in an apartment, the admissions office is putting together an email list of people that have vacancies in their apartment and need a roommate. You can call the admissions office and speak with Christina to be added to the list. She told me that she will try to send out the list in a couple of weeks.
dunamis22: I think having a car will be convenient in terms of getting around (food, rotations, part-time work, etc), but $328/semester for parking is ridiculous. That said, I will have a car if I decide to live on-campus.
