<p>OP: Harvard has Sigma Chi, SAE, and AEPi. Sigma Chi (I believe) has a house, but only a few people live in it. SAE + AEPi just throw parties in dorm rooms/common areas.</p>
<p>There are also three sororities… Delta Gamma, Kappa, & Theta. Same deal, not recognized by the university + don’t have houses.</p>
