Executive Summary

Illinois construction stands at a crossroads. After three consecutive years of population growth — adding 16,108 residents between July 2024 and July 2025 alone 1 — the state has reversed a decade of demographic decline. Yet growth remains uneven: Chicago's northern lakefront and collar counties such as Kane, Kendall and Will show strength, while South Side neighborhoods and rural counties face continued contraction.

Employment signals are positive in aggregate but fragile. Illinois added 7,300 construction jobs, or 3.0 percent, between April 2025 and April 2026, placing it among the top five states for job gains 2. Real gross domestic product for construction in Illinois reached $28,656.5 million in Q4 2025 on a chained 2017 dollar basis, up from $27,662.0 million in Q1 2025 3. Nationally, total construction spending was estimated at a seasonally adjusted annual rate of $2,210.2 billion in May 2026 4.

At the same time, cost pressures, financing constraints, and a historic labor shortage compress margins for small and mid-sized firms. Ninety-two percent of construction firms report difficulty filling open positions 5, while Associated Builders and Contractors reports backlog at 8.8 months in June, down 0.3 months from May but propped up disproportionately by data center work 6. Dodge Construction Network forecasts total construction starts to fall 0.4 percent in 2026 after a 6.1 percent increase in 2025 7.

1. Current State of Illinois Construction

Market Volume and Confidence

Illinois benefits from two countervailing megatrends: a $50.6 billion six-year transportation infrastructure program, the largest in state history 8, and a data center boom. Developers committed $10.7 billion to build 34 data centers in Illinois through 2025, with an estimated $666.6 million in tax credits over up to 20 years 9. Seven centers inked deals in 2025 alone, pledging $2.6 billion in investment.

However, Dodge and FMI forecasts suggest a soft landing. FMI expects total construction put-in-place to decline 1.4 percent in 2025 before rebounding 0.7 percent in 2026 7. Single-family housing remains soft, forecast to drop 1.9 percent in 2026 after a 9.5 percent decline in 2025. Multifamily is expected to grow 7.6 percent, health care facilities 17.4 percent, and highways and bridges 2.9 percent.

Key Driver

Rebuild Illinois / IIJA

Builder confidence reflects this bifurcation. The NAHB/Wells Fargo Housing Market Index fell to 36 in February 2026 on persistent affordability challenges 10. Yet 36 percent of builders cut prices, averaging a 6 percent reduction, while 65 percent used incentives.

Urban vs Suburban Dynamics

Chicago city reached 2,731,585 residents on July 1, 2025, up for a third straight year, though growth slowed to 5,253 11. Growth concentrates in northern lakefront neighborhoods and western suburbs. Southern and rural counties face material population loss, affecting demand for new single-family construction versus renovation and essential repair.

Key Insight: Illinois is no longer losing population, but demand is shifting toward renovation, infrastructure, and industrial-logistics rather than greenfield suburban single-family.
