According to recent research by the tenant-representation brokerage firm Mihalovich Partners, CBRE is the fourth largest controller of office space listings in San Francisco with 1.6 million sf or 7.3% of the 20 million sf of vacant space on the market. After its acquisition of Insignia/ESG--the seventh largest controller of office space listings in the city with 887,000 sf or 4.1% of available space--CBRE will control the leasing assignments for 2.49 million sf or 11.4% of available space.

That will put CBRE about 200,000 sf shy of The CAC Group, which controls 2.7 million sf or12.4% of the city's 20 million sf of available space. Had CBRE's merger with BT Commercial not been called off last month, it would have been about 200,000 sf ahead of CAC to become the biggest landlord representative in the city.

Regardless, Cushman & Wakefield, currently in second place with listings for 1.83 million sf or 8.4% of all available space, will be bumped to third place, and Colliers International, currently third with 1.64 million sf or 6.5% of vacant space, drops down to fourth place.
