SAN JOSE — A real estate investment group led by two tech heavyweights, including Uber co-founder Travis Kalanick, has bought a historic downtown San Jose building that over the decades has been a boxing gym, an Odd Fellow’s hall and a furniture store.

The purchase suggests that a widening group of well-heeled investors hunger for properties in downtown San Jose amid Google’s quest for a transit-oriented community near the Diridon train station of office buildings, shops, restaurants, homes and open spaces where up to 25,000 people could work, including 15,000 to 20,000 employed by the search giant.

“For decades, downtown San Jose was getting interest mainly from local investors,” said Mark Ritchie, president of San Jose-based realty firm Ritchie Commercial. “Now we are seeing a whole global group of investors who are getting interested in downtown San Jose.”

The building, with addresses ranging from 82 through 96 E. Santa Clara Street and next to South Second Street in San Jose, was bought on Nov. 30 for $7.3 million by an affiliate of City Storage Systems, Santa Clara County property documents show.

City Storage Systems is a tech-oriented real estate venture that Kalanick now heads up, according to a March 20 tweet from the Uber co-founder. Kalanick used a fund he established called 10100 to purchase what Kalanick stated was a “controlling interest” in City Storage.

In a followup tweet, Sky Dayton, founder of CloudKitchens, City Storage Systems, Earthlink, eCompanies and Boingo, which are tech ventures, stated he was enthusiastic about working with Kalanick on the new effort.

“Super excited to be working with Travis Kalanick and the team at City Storage Systems and CloudKitchens building a global network of tech-enabled real estate,” Dayton tweeted.

It’s the second time this year that the building has been bought — and the latest deal points to fast appreciation for downtown San Jose real estate.

On June 15, Pleasanton-based Leisure Sports paid $6.5 million for the three-story historic building, with plans to transform the property into a fitness club. However, Leisure Sports soon decided it preferred another downtown San Jose location for a Club Sport fitness outlet, and on Oct. 30, paid $15.5 million for the old Roos Atkins building at 2 N. 1st St., just down the street and around the corner from the furniture store site.

The arrival of the Kalanick venture at the historic furniture and Odd Fellows building could bring new kinds of restaurant-related activities to downtown San Jose, some observers said.

“It will be extremely exciting to see what the Travis Kalanick company will do with this property,” said Scott Knies, executive director of the San Jose Downtown Association.

Kalanick did not respond to requests for comment. But the restaurant and retail components of City Storage Systems appear to have caught Kalanick’s eye.

“Of particular interest are City Storage Systems’ leading B2B initiatives, CloudKitchens and CloudRetail, focused on real estate acquisition and development for the food and retail service industries,” Kalnick wrote on Twitter.

CloudKitchens stated on its web site that it provides software and real estate facilities that enable food operators to open delivery-only locations quickly and with minimal up-front costs.

“The company’s services “allow restaurants to capture existing demand from customers that want their food delivered,” according to the CloudKitchens’ site. The company’s technology can “provide customers with fast delivery and great a ordering experience at a fraction of the cost of existing delivery,” the web site stated.

The venture could help restaurant entrepreneurs and retailers in the area, Knies said.

“People can use a delivery app to get one-of-a-kind meals,” Knies said. “This can help bring more great dining to downtown San Jose.”
