Houston’s aging office towers are finally getting a second look. After roughly a decade in the doldrums, older buildings that have poured money into new lobbies, upgraded systems and shinier amenity packages are starting to land tenants who cannot squeeze into the city’s scarce new trophy space.
According to CoStar, older Houston office buildings recently posted positive absorption for the first time in 10 years, with renovated properties pulling in spillover demand from high-end space that is already tight. The April 3, 2026 piece describes the shift as a potential inflection point driven by targeted upgrades and repositioning efforts rather than a broad-based boom.
Numbers Hint At Momentum, But They Do Not Agree
Depending on which brokerage you ask, Houston’s office story ranges from “turning the corner” to “not so fast.” Colliers tallied 718,989 square feet of positive net absorption in 2025 and labeled it the city’s first annual gain since 2019, with the West Loop and CBD doing much of the heavy lifting. That read on the market suggests emerging pockets of strength even as overall leasing activity sits well below pre-pandemic levels. Colliers
Same Market, Different Math
Cushman & Wakefield’s take lands in a very different place. Its MarketBeat report for Q4 2025 pegged the year at roughly negative 1.2 million square feet of net absorption, a reminder that methodology and timing can push headline numbers in opposite directions. The firm also cautioned that “with fewer trophy options available and limited new space coming to market, tenants seeking modern, amenitized offices will have limited options.” Cushman & Wakefield
Owner-Users And Big Swings Clear Out Space
Another wrinkle: some of the “improvement” is coming from buildings leaving the leasing pool entirely. Industry coverage notes that more than 2 million square feet has been pulled off the market this cycle as owner-occupiers stepped in. Bisnow points to the city’s planned move into 1600 Smith and Energy Transfer’s purchase of 5555 San Felipe as headline deals that soaked up unusually large vacancies and reshaped the office supply picture almost overnight.
Conversions Rewrite The Supply Equation
Then there is the demolition-by-design angle. Trackers show roughly 6.7 million square feet of Houston office space is planned or underway for conversion, taking outdated properties out of the office column and easing some of the vacancy pressure that has plagued the market. That pipeline of adaptive reuse gives owners an alternative besides engaging in a pure rent war or endless amenity one-upmanship. CRE Daily
What Tenants And Landlords Should Keep An Eye On
With new construction muted and several big blocks either spoken for or headed for conversion, Colliers expects limited new supply and focused demand to keep the spotlight on the city’s best addresses while opening a lane for refreshed legacy buildings to outperform. Owners who put real money into HVAC, common-area overhauls and on-site perks look best positioned to lease up in what remains an uneven recovery. Colliers…
