Google has snapped up 300,000 sf at the Landmark Building at One Market, enough space to house more than 1,500 employees. The space was formerly occupied by Salesforce, who recently consolidated thousands of employees into their new HQ at 415 Mission St and their other existing buildings at 45 Fremont St and 350 Mission St.

Google moved fast to sign the lease at One Market, closing in on the deal when Salesforce made the decision to expand their South of Market urban campus by pre-leasing 325,000 sf at Transbay Parcel F, a proposed new office tower still years from completion.

The new lease increases Google’s San Francisco footprint by 30%, bringing their total leased square footage in the city to 1.28M square feet. In addition to this new location, Google also leases space at 345 Spear St, 121 Spear St, 2 Harrison St, and 188 The Embarcadero.
