LinkedIn has signed a lease for the entire 26-story building under construction at 222 Second St. There has been speculation for quite a while who would fill that space, as GlobeSt.com previously reported, and now we have the answer.

The City’s Office of Economic and Workforce Development estimates that the nearly 450,000 square feet of office space can accommodate approximately 2,500 jobs in San Francisco, said San Francisco Mayor Edwin M. Lee in making the announcement today. “As a national leader in job creation, San Francisco is the perfect home for a company that is connecting people to jobs, and I am pleased that LinkedIn is significantly expanding their presence here,” said Mayor Lee. “LinkedIn’s decision to grow in the Innovation Capital of the World demonstrates, once again, investor confidence in our City.”

Tishman Speyer Co-CEOs Jerry Speyer and Rob Speyer, says that they are pleased to welcome LinkedIn to its roster of tenants. “Our objective is to build the very best, sustainable office properties in the best cities around the globe, meeting the high quality space needs of leading organizations. We have had great results in San Francisco, successfully delivering signature office and residential properties to the market in the past several years, with more on the way.”

Headquartered in Mountain View, LinkedIn has been steadily increasing its presence in San Francisco. LinkedIn currently has 135,000 square feet at One Montgomery Tower and soon will be occupying 87,000 square feet at 505 Howard St.
