All dorms are on campus so therefore have close college proximity. Most of the dorms are inhabited by freshman. The majority move off campus after freshman year but you can elect to stay on campus the whole time you are in college.
In January, everyone living in a dorm receives an email and they have around 30 days to reply if they want to renew to stay in a dorm for the following fall. At this time, if you want to switch dorms, you put in that. There is a process for this and it has easy to follow instructions in the email.
The Commons is made up of four buildings; Mosher, Kruger, Aston and Dunn. The first three are the Engineering Village Living Learning Community. Not every Engineer elects to live in the Commons.
Engineering Honors Community of Scholars (ECOS) is a little different and you can read about all of it here.

Hullabaloo is one building and depending on when you were accepted into the university and when you applied for housing will have a HUGE effect on Hullabaloo being a possibility. It usually fills up very fast by auto/academic admits who were admitted when the first decisions were released (September/October).
If you elect not to live in the Engineering Villiage, you can live in any of the other dorms. Again, your date of housing contract will dictate your window for dorm selection. Make a list of where you want to live. If your first choice is a particular modular dorm, say McFadden, then your list needs to have your next choice if McFadden is full when your selection window opens. You should make a list of every dorm in order of preference, so that when your time slot opens, if something is already full, you can just go down your list instead of trying to figure it out during your selection time, as more and more rooms are reserved. Go in prepared. Better to have the whole list and not need it, than to need it and not have it.
You also can choose to live in one of the campus apartments, Whitecreek or The Gardens.

Here is a great map to show where everything is located on campus https://www.tamu.edu/map/index.html
It doesn’t matter where you reside your first year. Your freshman classes will be all over the campus anyway in most cases and you will spend a lot of time walking or taking a bus to and fro.
