Here in Springfield, MO there is a restriction in a neighborhood just south of the biggest university in the city (there are other, smaller, U's also). I believe it is a city ordinance & limits to a max of 3 unrelated persons in the dwelling. I suppose it wouldn't be a FH issue if it's not a landlord decision but is a city zoning/ordinance issue? Of course students are not a protected class but I don't think it says a limit on the amt of students, but it limits unrelated persons
