IRL my former landlord cooked for me. It was in our rental agreement, and he did that because he was a former cook, so he just "sold" that as a plus. Some others are ok with laundry, some with keeping the place clean. In a suburban setting is not that unusual to find a couple who rents a room to a student and basically acts like his/her parents (chores-wise).
(Of course if you live in the same building or share the house, I don't think it happens when the landlord/landlady lives in a whole other place.)
