Ours says the same thing, then seems to expand on that:
1.lives and cooks together in a residence as a "single housekeeping unit"The quotes, I think, are from some court opinion.
2.shares expenses for food, rent, utilities or other household expenses
3.is, "to all outward appearances, a relatively normal, stable, and permanent family unit"
4.is not "a temporary living arrangement as would be a group of college students sharing a house"
5.will inhabit a dwelling which does not provide "a framework for transients or transient living.”
6.shares the entire house
7.includes one or more adults domiciled in the residence
