"Houses" v. "Chapters" / "Sororities"

[psy]

I know it's generally considered incorrect to refer to chapters on a campus as "houses" (e.g., "the other houses are doing X..." or "what house did you join?") for a number of reasons, but try as panhell did during recruitment to have everyone call them "chapters," everyone at my alma marter still said "houses," if just due to force of habit. I think part of it is that all of the current chapters at my alma marter are housed and have been in their current houses for at least 60-ish years (some for more than 90 years), so ABC's house is very much "the ABC house," historically. That, and most, if not all, of the houses were built specifically to house their current chapter.

I'm curious as to what people say/said at other campuses, particularly those with at least some housed chapters, and if chapters are ever called "houses" even at schools without sorority houses (I don't really see why they would be, but who knows?).
