Office tenants signed new leases for an estimated 120 million square feet during Q1 2026 – the highest quarterly total since mid-2018. This represented a 25% increase year over year and the first time this decade that quarterly volume exceeded its average from 2015-2019.

"While the quarterly figure signifies continued momentum for national office recovery, the composition of leasing activity reflects an intensification of patterns that have emerged in the leasing office market since the pandemic began," said Phil Mobley, national director of office analytics at CoStar Group. "First-quarter volume was driven by an exceptionally large number of transactions rather than a resurgence of large deals. In fact, the number of lease transactions executed during the quarter was the highest observed in a decade."

At the market level, nearly half of the 20 largest office markets in the U.S. have seen leasing volumes rebound to within 10% of their respective pre-pandemic averages over the last 12 months. Charlotte and New York City lead in recovery, supported by steady demand from banks and other financial institutions that have maintained higher in-office attendance and relatively stable headcounts. NYC's recovery has also been aided by continued leasing from technology firms tied to artificial intelligence, adding to the sector's diversified demand base.
