Why wide-open Idaho is mandating houses on the smallest lots in America
Idaho, a sparsely populated state, has implemented a new law requiring cities to approve housing on small lots. The law mandates a minimum lot size of 1,500 square feet, which is the smallest in the country. This move is notable given Idaho's vast open spaces and relatively low population density.
