crinrict I don't think you need a cheat code to set an affiliation. You just set up the club with sims in college and then when building the dorm you can just set it's affiliation to that club in the UI. Not sure why they'd add that feature if it wouldn't work properly from the start.
I also found this thread explaining how it should work.

Looks like we're talking about two different things again. I didn't check the uni housing, just the premade dorms according to that thread you linked.
To edit the dorms, you need a cheat. That's what I meant.
Changing this to uni housing to be more precise.
