Legal artificial intelligence company Harvey has expanded its presence at 201 Third Street in San Francisco, leasing two additional floors and bringing its total occupancy to about 150,000 square feet, according to an April 6 report from the San Francisco Business Times.
The expansion highlights ongoing demand for office space among artificial intelligence firms in the city. The move comes less than a year after Harvey first leased approximately 93,000 square feet in the South of Market building.
Kilroy Realty, which owns the property at 201 Third Street, has faced high vacancy rates; by the end of last year, only about 56 percent of the building was occupied. Kilroy CEO Angela Aman said that offering pre-built and furnished spaces was part of their strategy to attract tenants like Harvey. “AI firms are often attracted to move-in-ready offices like that, and Kilroy has been working to meet AI companies’ needs when trying to lease out property,” Aman said per the Business Times.
Harvey’s growth follows a recent $200 million fundraising round that brought its valuation up to $11 billion. Late last year it was valued at $8 billion and just months before that in mid-2025 it was valued at $5 billion. The company was founded in 2022 and is backed by the OpenAI Startup Fund.
Other artificial intelligence companies have also been expanding their footprints across San Francisco. OpenAI recently surpassed one million square feet with a new lease in Mission Bay last month. Anthropic added another three floors totaling 100,000 square feet at 400 Howard Street after previously leasing all of 300 Howard earlier this year. Reflection AI took two floors totaling about 25,000 square feet on New Montgomery Street last month while Databricks increased its presence with an additional lease for roughly 90,000 square feet at One Sansome Street.
The continued expansion signals strong demand from both established and growing AI companies for office space as they scale operations throughout San Francisco.
