SAN FRANCISCO—Those who follow @GlobeStcom on Twitter and @GlobeStLIVE may have seen a post teasing the announcement, but GlobeSt.com has learned that 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.

“With this new building, LinkedIn is committed to expanding in San Francisco, giving us even more access to some of the most talented professionals in the world across a variety of functions, including technology, sales, and operations,” says LinkedIn Head of Workplace Jim Morgensen. “We look forward to San Francisco becoming a larger part of our growing Bay Area presence.”

The new 222 Second St. was designed and is being constructed for LEED Gold certification, and will be ready for occupancy in early 2016. Along with other on-site and area amenities it will feature 8,500 square feet of public space.

“Today’s San Francisco office market is thriving, with companies recognizing the many advantages of a state-of-the-art building in a downtown location,” says Tishman Speyer senior managing director Carl Shannon. “This building was planned and designed accordingly, and we think LinkedIn is a perfect fit.”
