Q3 2025 U.S. office market overview
overall availability rate sees fifth consecutive decrease
The overall availability rate for U.S. office space sat at 22.8% in Q3 2025, comprised of a 19.8% direct availability rate and 3% sublet availability rate. Q3 2025 was the fifth consecutive quarterly decline in overall availability — a trend not seen since before 2016.
Quarter over quarter (QoQ), direct available space decreased by 13.2 million square feet (msf) and sublet available space decreased by 9.8 msf, netting a 23-msf decrease in total available space. While the availability rate remains historically high, this quarterly decrease in supply is a positive indicator for the U.S. office market.
total leasing activity in 2025 YTD
U.S. office leasing activity totaled 203 msf in the first three quarters of 2025 — down 15.4% from the pre-COVID average (2000–2019) of 244 msf, and 11.9% below 2024’s volume of 234 msf.
However, several key markets are showing strong momentum: San Francisco’s leasing activity is up 47% year over year, and Manhattan’s has risen 9%. Both are at or approaching pre-COVID leasing levels with San Francisco 17% below, while Manhattan trails by just 3%.
growth in trophy leasing over pre-COVID average (2015-2019)
Despite overall office leasing across the country still well below pre-COVID levels, the trophy segment of the market is outperforming historical norms. Over the last four quarters, trophy leasing in major markets is 12.5% higher than the pre-COVID average (2015–2019, rolling four quarters).
Class A product remains 19.9% below pre-COVID levels but has grown in recent quarters as availability in trophy assets shrink.
Class B/C leasing, which was already falling in the years leading up to the pandemic, sits 32.8% below the pre-COVID average.
