Fire Alarm System Modification at 110 N Wacker Dr

Building owners and managers in Chicago's Loop can find information on the costs associated with upgrading or modifying fire alarm systems in commercial high-rise buildings. This permit details a modification to an existing system, affecting a non-residential unit on the 37th floor.

This permit is active and was issued on July 23, 2026. While the permit fee was $175, the actual project cost for such a modification in a high-rise building, including voice communication and special locking features, would be significantly higher and should be estimated based on the scope of work.
