Since the 1970s, the county has had in place a Moderately Priced Dwelling Unit (MPDU) zoning plan that requires developers to include affordable housing in any new residential developments that they construct in the county. The goal is to create socioeconomically mixed neighborhoods and schools so the rich and poor are not isolated in separate parts of the county. Developers who provide for more than the minimum amount of MPDUs are rewarded with permission to increase the density of their developments, which allows them to build more housing and generate more revenue. Montgomery County was one of the first counties in the U.S. to adopt such a plan, but many other areas have since followed suit.
