In Atlanta, loosely written zoning regulations allow large houses to be built on small lots. City Councilwoman Mary Norwood convinced Mayor Shirley Franklin to impose a moratorium on infill development in four Atlanta neighborhoods; however, the City Council's Zoning Committee defeated the measure. Norwood claims that super-sized houses destroy the ambiance of neighborhoods and can depress existing home values. According to her: "Some people say this isn't a crisis. I say this is a crisis."
