Legally, our MEP engineers at Yadavian engineers determine this based on the characteristics of the building you reside in. In accordance with the Chicago City Building Code, office buildings, whether high-rise or low-rise, are required to install an emergency power system.

For High-Rise Office Buildings:

All high-rise structures must adhere to the official standards outlined by NFPA and implement an emergency generator system.

For Low-Rise Office Buildings:

These buildings will incorporate the system if an occupied floor is within seventy-five feet of fire truck access and if the total floor area exceeds fifteen thousand square feet, or one hundred thousand square feet for the entire building.
