I work for a community in Virginia that is experiencing a boom in the number of what most people would consider to be overcrowded houses. Commonly these are houses occupied by minority families that have moved to the area in search of employment. We have cases of more than 20 people, men, women and children living in 2 bedroom, 1 bath houses. Though our zoning code restricts occupancy to 4 or fewer un-related individuals, in these case they are extended families - aunts, uncles, nephews, etc. Has anyone dealt with this issue in a manner that is effective and defendable in court?
