NBC Insider spoke with co-executive producer Demetra

Diamantopoulos to get the scoop on filming locations.

Whether it’s a heart-racing rescue mission or a blazing inferno,

it’s never a dull day for the Chicago Fire cast and crew. When Firehouse 51 gets a call on the show, it’s all hands on deck as the dedicated firefighters go wherever the chaos leads them next. With 12 seasons and counting, Chicago Fire fans have seen fan favorites scale skyscrapers, jump from burning buildings, and pull off life-threatening rescues all beneath the sprawling Chicago skyline.

Many Firehouse 51 scenes are filmed at Cinespace Film Studios — the studio that houses all three One Chicago series — but many interior and exterior Firehouse 51 scenes are filmed on-site at the local firehouse. Chicago Fire’s production is very grateful for the engine’s hospitality and support.

“Engine 18 is our second home!” Diamantopoulos said. “We find ourselves filming there at least three days a month. The members of that house treat us well and we feel that they are part of the Chicago Fire family. It’s no easy task for them to make room for us and still meet the needs of the community they serve.”
