Pill Hill is a small collection of blocks located in the Calumet heights neighborhood. According to The Electronic Encyclopedia of Chicago, the neighborhood is the more affluent portion of the Stony Island Heights neighborhood that occupies the eastern two-thirds of Calumet Heights. Several sources more loosely define Pill Hill as the entire Calumet Heights region and use the names interchangeably to refer to the whole area. Other sources including one co-published by MSNBC, clearly depict it as a rectangular neighborhood running for eight blocks bounded by East 91st or East 92nd street and East 94th or East 95th street to the north and south, respectively, and South Paxton Avenue and South Cregier Avenue to the east and west, respectively. The neighborhood is known for homes with built-in one-car garages and private yards. The region has little commercial development.
