Albert C. Hanna contends that the city of Chicago uses discriminatory zoning and landmark districts to maintain segregated communities. Here, he charts the number of new multi-family apartment buildings built within city limits. The 1971 ordinance change he refers to is a ban on the construction of 4+1 apartment buildings, which featured four floors of apartments and one level of parking. Because of this zoning change, Hanna believes the city has lost more than $1 billion in potential tax revenues.
