I don't think it's within the compound of school Issei goes to. Yes it's Kuoh Academy, but it's split into multiple division, primary, middle high, high and college division. And i don't think anyone would place all the divisions in a same location. Do you know how big of a space that would consume. Not only would people complain, it would have gone past the allowed allocated land for a school to be build at.
