Houston office market, lately

As of December 2025, Houston’s average office listing rates dropped 9.0 percent year-over-year to $27.53 per square foot, according to a recent Yardi Matrix report. The figure placed the metro at the bottom of the top 30 metros tracked by Yardi Matrix, alongside Twin Cities, Minn. ($27.38 per square foot), Orlando, Fla. ($26.56 per square foot) and Detroit, Mich. ($21.46 per square foot).

However, Houston recorded a steep improvement concerning its average vacancy rate, which plummeted 430 basis points over a 12-month period, to 20.2 percent. Peer markets that experienced sharp vacancy rate drops were San Francisco (-370 basis points), the Bay Area (-320 basis points) and Manhattan (-300 basis points).
