AI Firms Propel Office Leasing in San Francisco Amid Mixed Market Signals

In the first half of 2026, the San Francisco Bay Area's office leasing landscape has been significantly influenced by artificial intelligence (AI) companies. According to The Registry, these firms leased a remarkable 2.9 million square feet of office space, surpassing any previous full year’s total. This trend indicates a strong demand for office space as companies shift from discounted subleases to longer-term commitments in Class A buildings, contributing to a decrease in overall office vacancy rates in the region ³.

Despite this positive trend in office leasing, the market still faces challenges. The listing of 717 Market Street, an 81,000 square foot creative office building that is currently only 32% leased, underscores the mixed signals within the office market. While AI leasing activity is on the rise, properties with high vacancy rates continue to pose risks for investors ⁴.

In addition to the office sector, the multifamily market in the Bay Area remains robust. The recent sale of The Dylan, a 232-unit multifamily community in Hercules, for $83.5 million, reflects ongoing investor interest in multifamily properties. This transaction aligns with a broader trend of sustained demand for multifamily housing in the region, despite fluctuations in the market ¹.

Furthermore, development activity in San Francisco is on the rise, with Manna Capital filing plans for a new 45-story, 528-unit tower at 1601 Mission Street. This project includes 80 affordable units and reflects a continued push for new housing developments to address the ongoing housing shortage in the area ².

Overall, while AI companies are driving significant office leasing activity, the San Francisco Bay Area's commercial real estate market presents a complex picture, characterized by both opportunities and challenges across different sectors.
