Probably nothing. If the house meets building code regulations it is legal. You could try to plant some tall trees but that would not help very much. If the house were only one story high and there was no fence between the homes you would have the same problem [even though you could look into their bedroom]. Just as you have no right to an unobstructed view, you can not tell a neighbor where to put their windows.
