Office Market Update — 2025 Mid-Year Chicago Suburban Report

Our team at CBIZ Gibraltar is always monitoring conditions across office markets – and there are several key insights that can benefit tenants leveraging the current landscape for economic advantage.
In the suburban Chicago market, leasing activity saw a slight uptick towards the second half of the year with tenant demand focused on well located, high-quality and amenity-rich assets. Notwithstanding, overall market vacancy exceeds 30%.
Class A and Trophy assets continue to lead market activity, with O’Hare and Oak Brook submarkets experiencing a tightening of large, premium office space supply. Class A and Trophy office buildings are maintaining asking rental rates and, while landlords are still offering concessions as incentives to secure tenants, have started to spread them out over a period of the full lease term, allowing landlords to preserve face rates.
On the opposite spectrum, older and dated buildings are being redeveloped or repurposed, with a strong focus on common areas and amenity updates.
Sublease availability remains low and continued its downward trajectory, dropping to 1.9% overall. The North market currently offers the largest volume of sublease options among the suburban submarkets, at 3.1%.
Spec suites and well-maintained second-generation office spaces in amenity-rich buildings will continue to excel in the suburban market, with Class A and Trophy buildings experiencing the highest level of activity.
