Transfer/Sophomore housing?

is it normal for sophomores to live in campus dorms? I am very social and like to party and I’m especially looking forward to making new friends, so I think that living on campus would be good for me and help me get used to campus, but I don’t wanna live on campus if it isn’t a norm. I don’t wanna feel old or out of place. I would like to live somewhere in the north neighborhood because I’ve heard its the most social, and I plan to apply to the ONeill school and from my understanding, it is close to the north neighborhood. and lastly, if I apply to transfer in early May, will I miss the housing application deadline or will there be other complications?
