Pulse Analysis

Chicago’s industrial landscape is entering a new phase as developers cautiously expand the big‑box pipeline. After a two‑year boom that saw rapid absorption and soaring rents, the Q1 2026 Colliers report shows 18 projects—up from 13 a year earlier—totaling 10.2 million sq ft. The mix leans heavily toward build‑to‑suit (7.2 M sf) with speculative builds still modest, reflecting developers’ measured optimism amid lingering uncertainty about long‑term demand.

Rent growth has stalled, with starting rates slipping to $7.55 per sq ft, a slight dip from $7.65 last year. Landlords are countering flat escalations with concessions such as free rent, especially for the larger 500K‑749K sf tier that now commands $6.17 per sq ft. Smaller big‑box spaces (200K‑499K sf) retain a premium at $8.18 per sq ft, underscoring a demand concentration in more agile, mid‑size facilities. Vacancy climbed to 8.8%, driven by a surge in speculative deliveries and the re‑entry of second‑generation space, while the 500K‑749K sf segment posted the highest vacancy at 11.16%.

Leasing momentum remains a bright spot, with net absorption soaring 110% to 8 million sq ft and 24 new leases signed, including a marquee 1.2 M sf build‑to‑sit for RJW Logistics. However, the average leasing cycle has doubled to two years, indicating tenants are more deliberate. Analysts expect vacancy to ease into the low‑eights later in the year as large tenants occupy their spaces. For investors, the current environment offers a blend of risk and opportunity: steady demand supports cash flow, but the plateau in rent growth and rising vacancy require disciplined underwriting and a focus on asset quality.
