Executive Summary
Downtown Houston’s office market showed continued signs of stabilization in 2025, with improving leasing activity, tightening marketed space, and a gradual shift toward a more balanced occupier base. While the market remains below pre-pandemic leasing norms, the data points to a clearer recovery pattern as tenants continue to make long-term real estate decisions and underperforming office assets are increasingly removed from the competitive market.
Total marketed space declined in 2025, driven by a combination of lease-up activity, reduced sublease availability, and the removal of obsolete or no longer competitive office space from the surveyed inventory. Direct marketed space decreased across Tiers I and III, while Tier II remained essentially flat. At the same time, marketed sublease space fell year-over-year to one of its lower levels in recent years, suggesting that market conditions are improving even as overall availability remains elevated by historical standards. Tier II buildings continue to hold the largest share of direct marketed space, highlighting an ongoing challenge for lower Class A assets that must compete against both highly amenitized Tier I properties and more cost-effective Tier III alternatives.
Leasing activity also improved for the second consecutive year, totaling more than 2.4 million square feet in 2025, a 8.5% increase from 2024 and a 17.2% increase from 2023. New leasing activity rose 18% year-over-year, while renewal activity remained a major driver of total transaction volume. This suggests that more tenants are recommitting to Downtown and, in many cases, are no longer reducing their footprints as aggressively as they did during the earlier post-pandemic period. However, overall leasing volume remains well below long-term historical averages, underscoring that the recovery is still ongoing.
The occupier base remained relatively stable, with energy tenants continuing to account for the largest share of occupied space. However, Downtown’s industry mix continues to diversify, with legal and FIRE tenants increasing their share of total occupancy. Legal and FIRE tenants remain especially concentrated in Tier I buildings, while energy tenants occupy a wider range of building types and price points. This diversification is a positive long-term signal for Downtown Houston, as a broader tenant base can help reduce the market’s exposure to industry-specific disruptions.
Overall, the 2025 Office Story reflects a market moving toward a new equilibrium. Downtown Houston continues to face challenges, particularly around elevated availability, uneven demand across building tiers, and leasing activity that has not yet returned to historical norms. At the same time, the market is showing measurable improvement: marketed space is tightening, sublease pressure is easing, new leasing is increasing, and large and mid-sized occupiers are beginning to show signs of recovery. These trends suggest that Downtown’s office market is not fully recovered, but it is becoming healthier, more clearly defined, and better positioned for long-term stability.

Why do we do this study?
• Proprietary and longitudinal: Report is in its 42nd year of publication, started in 1985 by Stewart O. Robinson
• Downtown’s office inventory is heavily concentrated in Class A space, which accounts for approximately 75% of total inventory. However, performance varies significantly within that Class A segment, with a clear divide between higher-performing and lower-performing properties
• To better capture these differences, surveyed buildings are organized into three tiers. This tiering approach helps highlight trends among Downtown’s top office towers, including newly constructed and recently renovated properties, while also distinguishing them from older or lower-performing assets
• Tier I: Top-tier Class A properties, including the newest, most highly amenitized, and best-positioned office towers
• Tier II: Lower-tier Class A properties that remain competitive but generally lack the same level of positioning, amenities, or performance as Tier I assets
• Tier III: Generally, Class B properties, including older or less competitive office buildings
• A unique Downtown Houston office survey that includes:
• Marketed space
• Large available blocks and full floors
• Tenants by industry
• Marketed sublease space
• Multi-floor tenants
• Large transactions and tenants new to Downtown
• This report surveys buildings that are actively marketing space for lease; it excludes spaces that are owner-occupied and spaces are not being competitively marketed
• Survey conducted January – May 2026, covering all 2025 leasing activity
• Approximately 31.3 million SF surveyed
• 37 office buildings included
• More than 2.4 million SF of Downtown leasing in 2025
• Survey represents 60% of Downtown office inventory, and 81% of leasable Downtown office inventory
Surveyed Buildings
Buildings no longer included in survey due to change in use or marketability:
• 919 Milam
• 500 Jefferson

2025 MARKET ANALYSIS
Marketed Space
Marketed Space
Overview
• In 2025, the market for direct space tightened by 360,000 square feet
• Marketed sublease space decreased year-over-year, from 783,000 square feet in 2024 to 459,000 square feet in 2025
• Tier II and III properties account for 95% of available sublease space
• Tier Breakdown:
• Tier I: The market tightened by 245,000 square feet, with a majority of buildings reducing marketed space compared to 2024. 700 Louisiana and 811 Main saw the largest shares of reduced footprints, both decreasing available space by over 100,000 square feet
• Tier II: The market remained essentially flat, loosening by 5,000 square feet. Performance varied building to building in Tier II space.
• Tier III: The market tightened by 120,000 square feet. While activity varied building to building, Tier III performance is partly due to leasing, but also due to the removal of obsolete space.
• Tier I change in marketed space is primarily due to leasing activity; This trend would be more pronounced, but Hess Tower added over 200,000 square feet of direct marketed space to Tier I inventory.
• Tier II buildings represent 56% of total direct marketed space
• Tier III continues to improve largely due to the removal of obsolete space

TAKEAWAYS
• Direct marketed space decreased across Tiers I and III, while Tier II remained essentially flat
• Tiers I and II recorded lease-up activity, while Tier III benefited largely from obsolete space being removed from the market
• Owner-occupiers and conversion activity are creating new opportunities
• Space is being taken offline as public and large entities capitalize on opportunities to purchase office assets at lower costs. Additionally, conversion projects are being pursued for underperforming office properties
• Tier II buildings hold the majority of direct marketed space
• This trend has also been observed in quarterly reporting, where Class B space has outperformed lower-quality Class A product in terms of occupancy
• Overall, marketed space conditions are improving
• Leasing activity has shown signs of improvement, while the removal of obsolete space is helping provide a clearer picture of market fundamentals. Taking underperforming assets offline is a positive development, as these properties can weigh on overall market KPIs

2025 MARKET ANALYSIS
Leasing Analysis
Leasing Analysis Overview
• Leasing activity rose 8.5% year-over-year, totaling over 2.4 million square feet
• This marks the second consecutive year of growth in leasing activity
• New leasing activity increased 18% year-over-year, with 845,000 square feet of new leases signed
• These trends reflect broader market trends, with the larger Houston market seeing condensed leasing activity in top-tier buildings, with lower-class buildings struggling to attract tenants.
• While Downtown saw leasing activity improve in 2025, Houston overall saw lower leasing activity compared to previous years.
Tier Breakdown
• Tier I: Tier I recorded strong new lease and renewal activity, though expansion activity was down slightly compared to 2024.
• Tier II: Total leasing activity increased 28% year-over-year. Renewals accounted for 72% of Tier II activity, driven in part by two large renewals totaling approximately 400,000 square feet.
• Tier III: Tier III saw lower levels of new lease and expansion activity, but renewal activity remained strong, increasing 76% compared to 2024.
