Yeah, USD Greeks do not have school sponsored housing. The only school in San Diego to have houses is San Diego State.

Btw, I don't know if you meant to include them under the category of Jesuit schools, AOE2APhi, but USD is not a Jesuit school.

Loyola College in Maryland has Alpha Phi Omega service fraternity, but even *that* ran into a lot of resistance from elements of the administration. I can't even imagine getting a recognized national social fraternity or sorority.
