Tenants searching for «Chicago office building rent by class» want one thing: a sense of what an address costs before they call a broker. Class A, B and C are not official grades — they are shorthand for age, systems, lobby and location. Below are the asking rates our listing actually carries for the buildings people search by name, so you can see where each one lands.
How the classes translate into price here
Across 630 listed Chicago offices, asking rents run $1.16 to $6.97 per ft² a month, typically $2.69. Trophy and Class A towers in our set mostly quote $2.10–$3.10 for full floors and above $4 for small fitted suites; Class B stock in the older Loop blocks sits nearer $1.70–$2.60. The counter-intuitive part is that the grandest addresses are not the most expensive per foot, because they lease the biggest plates — compare them yourself in the Chicago office listings.
