How Single-Family Zoning Segregated America’s Cities
By the end of the Civil War, White Americans had accumulated wealth for nearly three centuries and had made the single-family home an iconic element of American culture. In contrast, the millions of newly freed Black Americans started their lives with no money, limiting them to multifamily housing, such as apartments and duplexes. In 1916, a real estate developer in Berkeley, California, who had used racial covenants to build Whites-only neighborhoods, became concerned about how the property adjacent to his developments was being used. Since the NAACP was suing to end racial zoning, he needed a different way to restrict who could occupy land he didn’t own. Under his guidance, the city council enacted the nation’s first single-family zoning ordinance. This government restriction on how private property owners could use their land would prove to be long-lasting.
In their 1926 decision in Euclid v. Ambler, the US Supreme Court sided with the segregationists, who were then free to zone large swaths of cities exclusively for single-family homes. White lawmakers used this zoning to control where Black residents could live in major cities and suburbs, allocating up to 75% of the land to single-family homes. In 1940, a Detroit builder was denied FHA insurance for a single-family housing development next to an existing Black neighborhood. The builder then constructed a half-mile concrete wall, six feet high and a foot thick, to separate the neighborhoods, physically preventing Black people from entering the new neighborhood. The FHA subsequently approved the loan. The wall still stands, and in 2021, it was added to the National Register of Historic Places.
A UC Berkeley study found that cities with the highest rates of Black migration from the South between 1940 and 1970 have the most exclusionary zoning laws. Single-family zoning, which originated from anti-Black sentiment, has produced higher housing prices for everyone by artificially limiting the housing supply. In 2018, Minneapolis became the first major US city to eliminate single-family zoning, and in 2019, Oregon became the first state to do the same.
