SAN FRANCISCO-Pac-12 Enterprises has signed an 11-year, 70,000-square-foot lease at 370 Third St., an office building in the SoMa District. Pac 12, a sports-related media company that handles broadcast licensing and event planning for the Pac-12 Conference, plans to make its headquarters in the space. The owner is Kilroy Realty Corp. of Los Angeles.

The multi-floor lease includes both office space and a television studio, which Pac-12 Enterprises says it will use to broadcast more than 850 live sporting events annually. Those events include all conference football games and men’s basketball games that aren't carried by the firm’s national telecast partners, ESPN and FOX.

The space is to serve as headquarters and operations hub for three of the company divisions: Pac-12 Networks, Pac-12 Digital Network and Pac-12 Properties.
