Production
The series pilot, co-written by creators Michael Brandt and Derek Haas, was filmed in Chicago and, according to an NBC representative, the series will continue to be filmed there. Mayor of Chicago Rahm Emanuel made an appearance in the series' pilot episode. Emanuel stated: "It's easier being mayor than playing mayor. I told them I'd do it under one condition: the TV show is making an investment to the Firefighters' Widows and Orphans Fund".

The network placed an order for the series in May 2012. After receiving an additional script order in October, Chicago Fire was picked up for a full season on November 8, 2012. On January 29, 2013, Chicago Fire had its episode total increased from 22 to 23. One week later, on February 6, 2013, Chicago Fire received one more episode, giving it a total of 24 episodes for season one.

The firehouse shown is Engine 18's quarters, located at 1360 S. Blue Island Ave. between 13th & Racine. Housed here is Engine 18, 2-2-1 (Deputy District Chief - 1st District), 4-5-7 (Paramedic Field Chief - EMS District 7), 6-4-16 (High-Rise Response Unit), and Ambulance 65.

Spinoff
On March 27, 2013, NBC announced plans for a proposed spin-off of Chicago Fire.
