The San Francisco office market is entering a materially different phase than it occupied just 12 to 18 months ago. Is this the comeback no one expected?
Because while overall vacancy remains elevated, multiple leading indicators—including leasing activity, tenant requirements, net absorption, and capital reengagement—now point toward stabilization and early recovery, particularly at the high end of the market.
For corporate real estate executives and large-scale tenants, San Francisco’s trajectory matters beyond the Bay Area. Historically, the market has acted as a forward indicator for national office trends, especially in innovation-driven metros.
As the industry looks toward 2026 and beyond, the data emerging from San Francisco provides critical insight into what the next office cycle is likely to look like across the U.S. Let’s go deeper.
Leasing Activity Reflects A Fundamental Shift In Demand Composition
Leasing activity in San Francisco accelerated meaningfully in 2025, reversing several years of contraction and signaling renewed occupier engagement.
According to an industry Q4 2025 Office Leasing Market Summary:
- 10.2 million square feet of office space was leased in San Francisco in 2025
- AI companies accounted for 25% of that leasing activity
- 2.5 million square feet of space was leased by AI firms alone—the highest annual total since 2018
AI-driven leasing is largely concentrated among well-capitalized companies with long-term growth horizons, which has implications for lease duration, credit quality, and space selection.
And go figure, the same AI technologies widely expected to reduce long-term office demand are currently among the strongest drivers of leasing activity. This also mirrors the Silicon Valley Boom of early Facebook and Google days.
What’s Different This Cycle:
- Demand is highly selective, not broad-based
- Leasing is concentrated in best-in-class buildings
- Space decisions are being tied directly to innovation, collaboration, and talent strategy
For occupiers, this reinforces that office space is once again being treated as a strategic input, and a big cost worthy of appearing on a balance sheet.
Net Absorption Turns Positive For The First Time In Years
One of the most consequential data points in 2025 was the return of positive net absorption. Industry reports point to:
- 2.2 million square feet of positive net absorption in 2025
- AI companies drove 82% of that absorption (approximately 1.8 million square feet)
- The previous absorption peak was 3.9 million square feet in 2018
Positive net absorption marks a critical inflection point. It signals that leasing activity is no longer simply recycling space but is reducing overall availability—a prerequisite for any sustained recovery. This is an incredible comeback from an area choked by unprecedented vacancies and urban decline.
Why This Matters For CRE Leaders:
- Absorption typically leads vacancy improvement
- Vacancy improvement precedes pricing power
- Pricing power eventually drives asset value stabilization
Vacancy Remains Elevated—But The Direction Has Changed
Despite years of strikingly negative headlines, vacancy metrics are now moving in the right direction.
Key vacancy data from Q4 2025:
- Overall vacancy declined to 33.5%
- This represents a three percentage point year-over-year reduction
- The decline marks the largest annual vacancy improvement since 2011
It is critical to note that vacancy reduction is not uniform across the market.
- Trophy and Class A buildings are experiencing the fastest improvement
- Lower-quality and poorly located assets continue to struggle
- Submarkets with modern inventory and strong transit access are outperforming
This bifurcation reinforces the reality that the recovery is asset-specific, not market-wide. This is a national trend appearing very acutely in San Francisco.
Tenant Demand Is At A Record High—Despite Elevated Vacancy
One of the most forward-looking indicators of future performance is tenant intent, not just executed leases. Industry reports point to:
- Tenants are currently seeking eight million square feet of office space in San Francisco—an all-time high
- Approximately three million square feet of this demand represents expected net absorption growth
- AI companies account for 2.8 million square feet of active requirements
- AI firms represent 1.7 million square feet of expected net absorption
This demand exists despite more than 30 million square feet of vacant space, underscoring how quality and suitability—not raw availability—are driving decisions.
Implication For Occupiers: There is a narrowing window to secure top-tier space before competition increases and concessions begin to compress in high-demand buildings.
Capital Markets Reengage As The Bid-Ask Spread Narrows
Improving leasing fundamentals have been accompanied by renewed capital market confidence.
According to GlobeSt and market participants:
- The bid-ask spread has meaningfully narrowed
- Institutional equity and lenders are reentering the market
- Transactions are increasingly grounded in realistic pricing, not forced distress
This shift has unlocked:
- Repositioning strategies for underperforming buildings
- Acquisitions trading below replacement cost
- Renewed interest in land and selective development opportunities
Importantly, capital is no longer frozen by uncertainty—it is selectively targeting assets aligned with post-pandemic demand patterns.
San Francisco As A National Leading Indicator Heading Into 2026
San Francisco’s recovery matters because it reflects a pattern likely to repeat nationally.
Key national implications:
- Top-tier assets recover first in every cycle
- Office demand is evolving, not disappearing
- Vacancy compression will be slow, uneven, and quality-driven
- Rent growth will lag fundamentals, likely into late 2026
Markets that share San Francisco’s characteristics—deep talent pools, innovation-driven industries, institutional capital, and improving governance—are positioned to follow a similar trajectory.
Outlook: A Selective, Data-Driven Office Recovery
Looking ahead, the San Francisco office market is not poised for a rapid rebound—but it is firmly in recovery mode.
Expectations for 2026:
- Continued demand growth, led by technology and AI
- Further reductions in vacancy, concentrated in Class A assets
- Concessions to remain elevated in lower-tier buildings
- Gradual improvement in pricing and asset values
The next office cycle will reward precision, patience, and portfolio optimization—not broad exposure.

- Q4 2025 vacancy: 33.5%, down from the prior year
- Vacancy declines are asset-specific, not market-wide

For decision-makers, the direction of change is more important than the absolute number at this stage of the cycle.
What Types Of Office Space Are Seeing The Most Demand?
Demand is concentrated in high-quality, well-located office space.
Most sought-after characteristics include:
- Trophy and Class A buildings
- Modern infrastructure and efficient floor plates
- View space and strong natural light
- Locations requiring minimal tenant improvements

This bifurcation reinforces the growing performance gap between best-in-class assets and commodity office space.

- AI companies accounted for 25% of all leasing activity in 2025
- They represent 12% of total occupied office space

This reflects a market where quality matters more than quantity.
What Does This Mean For Large Office Tenants In 2026?
Large tenants are entering a strategic window of opportunity.
