Tenants in the West Loop are signing leases for substantially less space than before the pandemic, while landlords of Class B properties face vacancy rates above 31 percent as of mid-2024. Average leased office space in premier West Loop properties has dropped by over 40 percent post-pandemic, falling from roughly 30,000 sq ft to approximately 18,000 sq ft per lease. This shift forces tenants to reconsider how much space they need and gives landlords of higher-quality buildings an edge in attracting occupants.

Lease Size Reductions Alter Tenant Strategies

The reduction in leased square footage directly affects how companies plan their operations in the West Loop. With average leased office space dropping from roughly 30,000 sq ft to approximately 18,000 sq ft, tenants are consolidating footprints and negotiating shorter or more flexible terms. Properties such as the nine-story loft at 600 W. Fulton Street, expected to sell for about $18 million, illustrate the pricing pressure that can extend to rental discussions. Tenants must weigh these smaller commitments against the need for space that supports hybrid work patterns.

Class B Vacancies Create Landlord Challenges

Landlords of Class B buildings contend with vacancy rates that have surged to over 31 percent as of mid-2024, compared with 15 percent for Class A buildings. This gap means owners of lower-tier assets often accept steeper concessions to retain or attract tenants. The 46-story tower at 500 W. Monroe St. sold for less than $100 million, a 76 percent discount from its 2019 value, underscoring the broader valuation strain that can influence rental pricing across the submarket.

Investment Moves Highlight Selective Demand

Recent transactions show continued interest in stronger assets. LaSalle Investment Management acquired the 30-story Class A tower at 123 N. Wacker Drive for $147 million, while Neuberger Berman signed a 52,000 sq ft lease at 191 North Wacker. These deals indicate that tenants with larger requirements still target Class A space in the West Loop and adjacent Fulton Market, leaving Class B landlords to compete more aggressively on price and terms.

Market participants can expect continued pressure on Class B rents and a focus on Class A properties that maintain lower vacancy. Tenants evaluating new space should compare Class A and Class B options directly, while landlords may need to adjust offering terms to match the reduced average lease sizes now common in the neighborhood.
