What was permitted
For those in Chicago's Loop, understanding the costs of building system upgrades is key, as seen with the fire alarm modification at 123 N Wacker Dr. This project focuses on updating the existing fire alarm system within a high-rise building.
This express permit, issued on August 3, 2026, involves modifications to the fire alarm system on the 1st floor, with voice communication and supervising station monitoring. Chicago Fire Detection Systems LLC is the contact for this project.
