Reach out to Wayne State University in Detroit. They have a pretty strong Greek system and are urban, commuter.

I'm not at a commuter school, but I personally feel like wanting to have a sense of community is something that everyone wants. So, that can be even more important for students where that sense is not the norm. Sure, there are going to be those that just want to go to their classes and get their degree, but for the ones that are there because they are from that city, but still want to have a fulfilling experience, having a fraternity or sorority to join can make all the difference.

I'm at a suburban mostly commuter school, and the greek life is actually big for a school of its size. From what I've heard from them (I dorm) it's to get more involved since a lot of times commuters will pretty much do home-class-home and want more involvement on campus.

Since there is no football team, do your important student-interest Homecoming festivities coincide with a Division I basketball season? And is basketball the sport most highly attended by students, or would moving Homecoming to a different sport bring higher interest/student attendance?

Knowing that most commuter schools have at least these areas, may I ask: does your on-campus library or student cafeteria have designated greek org tables/rooms available as mini-publicity, where a non-greek student might make a greek student introduction?
