- Dunning Branch opened May 6, 2011.
- Dunning Branch serves an area that takes its name from the community originally settled just after the Civil War by farmer-turned-real estate developer Andrew Dunning. Dunning later took on significance as the original name for the state hospital, municipal poorhouse and cemeteries that occupied land along the community’s northern boundary.
- The Chicago Board of Education donated the land on which the branch sits.
- The U.S. Green Building Council granted Dunning Branch gold certification under the Leadership in Energy and Environmental Design (LEED) Green Building Rating System.
