What about a house with two siblings and two additional roommates? Or two cousins and two additional roommates?
ANSWER: Neither of these arrangements would be in violation. In the first scenario, the siblings would be related to each other. Because the siblings are related, there would not be more than three unrelated persons in the home. The same applies to the two cousins and two additional roommates scenario. Because the two brothers are related, there would not be more than three unrelated persons in the home.
