Pittsburgh, PA – Southwestern Pennsylvania's industrial market remained stable during the second quarter of 2026, with vacancy holding nearly flat, asking rents increasing, and limited large-block availability continuing to shape tenant options across the region, according to Lee & Associates of Western Pennsylvania’s Q2 2026 Industrial Intel report.
The report tracks industrial buildings of 20,000 square feet and larger across Allegheny, Armstrong, Beaver, Butler, Fayette, Washington, and Westmoreland counties. Regional vacancy ended Q2 at 4.77%, up slightly from 4.72% in Q1, while availability edged from 5.81% to 5.86%. The region remained well below the national industrial vacancy rate of 7.20% for the same subset of industrial properties.
“Southwestern Pennsylvania’s industrial market does not move in dramatic swings, and that is part of the story,” said Heather Kreiger, CCIM, Regional Research & Marketing Director and Principal at Lee & Associates of Western Pennsylvania. “Limited speculative development, a large base of functional legacy inventory, and steady local and regional demand have helped keep vacancy within a relatively tight range over time.”
Unlike larger national logistics markets that saw significant speculative development during the last cycle, Southwestern Pennsylvania has remained a more regional, user-driven industrial market. Class A buildings represent only 10% of the region’s standing industrial stock, while Class B accounts for 40% and Class C represents 50%. That mix has helped moderate the vacancy swings seen in larger, more heavily developed distribution markets.
Vacancy across building classes was tightly grouped in Q2, with Class A at 4.71%, Class B at 4.24%, and Class C at 5.20%. Lee & Associates noted that Class A vacancy was elevated for part of the post-COVID development cycle, but much of that space has since been absorbed. Over the past year and a half, vacancy across all three building classes has converged, suggesting relatively balanced market conditions across newer Class A space and the region's legacy industrial inventory.
Leasing activity remained steady in Q2. Leasing activity totaled 767,091 square feet during the quarter. Although quarterly volume was below Q1 levels, trailing twelve-month leasing continued to improve, moving closer to activity levels recorded in 2023 and 2024. Average lease size also continued its gradual recovery, ending Q2 near 43,000 square feet after reaching its recent low point in 2024. The quarter included a reported 226,257-square-foot lease by United States Steel at 601 West 7th Avenue in Homestead, the largest significant lease event listed in the report.
Regional asking lease rates increased during the quarter. The average asking lease rate increased from $7.69 per square foot in Q1 to $8.54 per square foot in Q2. Lee & Associates attributed the increase to limited supply and the mix of available product, while noting that actual lease economics remain dependent on building quality, size, location, lease term, and tenant-specific requirements.
Large blocks remain especially limited. At the end of Q2, only six spaces over 100,000 square feet were available across the region. The limited availability of larger spaces has contributed to a historically smaller average lease size than is typical in major bulk-distribution markets. Multi-tenant light industrial and flex properties continue to support the local and regional businesses that make up much of the tenant base.
Allegheny County, which accounts for the largest share of the tracked regional industrial inventory, remained a central driver of the market story. The county contains 88.4 million square feet of industrial stock, or more than half of the region’s tracked inventory. Vacancy rose slightly from 5.07% to 5.20%, while availability increased from 6.16% to 6.57%. Net absorption remained positive at 11,845 square feet for the quarter, and Q2 leasing totaled approximately 467,000 square feet.
Lee & Associates characterized the market’s outlook as measured. The region had 10.2 million square feet in pre-construction at quarter-end, but only 871,340 square feet under construction. Much of the pipeline is expected to remain tied to build-to-suit or user-driven opportunities rather than broad speculative development.
“Limited growth is one of the main contributors to the market’s continued stability,” Kreiger said. “That can be a strength and a constraint. Southwestern Pennsylvania is attracting more attention from advanced manufacturing, technology, AI, and life sciences users, but it remains a market where new supply tends to follow specific user demand.”
Lee & Associates expects the region to remain stable over the next six to twelve months, with limited new supply, steady local and regional tenant demand, and leasing fundamentals expected to remain relatively balanced.
