I know at Elon, at least one chapter of the NPHC organizations on campus has a house. All of Elon's houses are owned by the university and sleep just 12 members of the organizations, so they're not big at all. The one that the NPHC chapters use is a half-house, like a duplex. Right now I think Phi Beta Sigma has six members in their half and Sigma Chi has the other half. We have a total of 12 houses on campus that house 13 chapters, and we have 20 IFC, NPC, and NPHC orgs on campus as well as a suite in a dorm. This will be the first year Alpha Chi Omega has a house on campus, and we're way excited about it.
The only picture I could find of the houses is
here. I'll keep searching to see if I can find more.
I've heard that AKPsi at UGA has a house. My little transferred there and says they have one.
