Inclusionary Zoning - Historical Background

Historical Background

During the mid- to late-20th century, new suburbs grew and expanded around American cities as middle-class house buyers, supported by federal loan programs such as Veterans Administration housing loan guarantees, left established neighborhoods and communities. These newly populated places were generally more economically homogeneous than the cities they encircled. Many suburban communities enacted local ordinances, often in zoning codes, to preserve the character of their municipality. One of the most commonly cited exclusionary practices is the stipulation that lots must be of a certain minimum size and houses must be set back from the street a certain minimum distance. In many cases, these housing ordinances prevented affordable housing from being built, because the large plots of land required to build within the code restrictions were cost-prohibitive for modestly priced houses. Communities have remained accessible to wealthier citizens because of these ordinances, effectively shutting the low income families out of desirable communities. Such zoning ordinances have not always been enacted with conscious intent to exclude lower income households, but it has been the unintended result of such policies.

By denying lower income families access to suburban communities, many feel that exclusionary zoning has contributed to the maintenance of inner city ghettos. Supporters of inclusionary zoning point out that low income households are more likely to become economically successful if they have middle class neighbors as peers and role models. When effective, inclusionary zoning reduces the concentration of poverty in slum districts where social norms may not provide adequate models of success. Education is one of the largest components in the effort to lift people out of poverty; access to high-quality public schools is another key benefit of reduced segregation. Statistically, a poor child in a school where 80% of the children are poor scores 13-15% lower compared to environments where the poor child's peers are 80% middle class.

In many of the communities where inclusionary zoning has been put into practice, income requirements allow households that earn 80-120% of the median income to qualify for the "affordable" housing. This is because in many places high housing prices have prevented even median-income households from buying market-rate properties. This is especially prominent in California, where only 16% of the population could afford the median-priced home during 2005.
