Mechanicsburg, PA – Lee & Associates of Eastern Pennsylvania has released their Q2 2026 Industrial Intel market report. Findings from the report indicate the Greater Philadelphia industrial market appears to have transitioned into a new phase of its market cycle characterized by normalization. Vacancy continues to decline, leasing activity remains healthy, construction has moderated, and the development pipeline has become more balanced following several years of rapid expansion.

Regional vacancy declined to 8.24% during the quarter as the market recorded more than 4.5 million square feet of positive net absorption and 10.3 million square feet of leasing activity, continuing the gradual improvement that began after vacancy peaked in mid-2025.

“The market feels considerably healthier today than it did a year ago with total vacant square feet declining by 10.1% YOY,” said Heather Kreiger, Principal and Regional Research & Marketing Director at Lee & Associates of Eastern Pennsylvania. “The extraordinary demand created during the pandemic wasn’t sustainable long term, and neither was the pace of speculative development that followed. What we're seeing in today's market is more consistent with conditions prior to the COVID era.”

One of the report's most notable findings is the continued shift within the construction pipeline. Regional construction activity declined modestly to 17.8 million square feet underway during the quarter. Speculative development now represents 63% of projects under construction compared with nearly 95% during the height of the recent industrial development boom. Build-to-suit projects now account for approximately 37% of the active pipeline, a composition more closely aligned with market conditions seen prior to the pandemic.

“The moderation in speculative construction was what the market needed,” Kreiger said. “Developers largely pulled back on speculative development throughout 2025 to allow the market time to absorb some of the oversupply. What we’re seeing now is the result of that discipline. There have been fewer speculative project starts and deliveries, which in turn has helped to ease upward pressure on vacancy rates.”

The report also highlights an important distinction between vacancy and availability. Although vacancy continued to decline, overall availability increased during the quarter as landlords are marketing space well before existing tenants vacate their facilities. While it is common for landlords to market space before existing tenants vacate, the increase also reflects continued tenant movement across the region rather than widespread market distress.

“Availability is one of the metrics we’re watching closely,” Kreiger said. “It isn’t necessarily a sign of weakening demand. In many cases, it reflects tenants optimizing their real estate footprints by relocating into newer buildings, expanding operations, or consolidating facilities. It’s an important leading indicator, but it needs to be viewed within the broader context of healthy leasing and improving absorption.”

Performance across the region’s major industrial submarkets generally reflected the broader normalization trend. Central Pennsylvania posted one of its strongest leasing quarters in recent years despite vacancy increasing following deliveries of a few spec buildings. Lehigh Valley recorded a second consecutive decline in vacancy while leasing activity reached its strongest quarterly total since the second quarter of 2025. Northeastern Pennsylvania posted improvements across nearly every major market indicator, while Southern New Jersey continued working through excess supply as vacancy declined for another quarter. Philadelphia Metro likewise continued its gradual recovery as vacancy improved for the fifth consecutive quarter.

Looking ahead, Lee & Associates expects the market’s gradual rebalancing to continue through the remainder of 2026 as construction activity remains measured, tenant demand continues, and the market works through available inventory.
