SAN FRANCISCO – The 443-unit Fox Plaza Apartments in San Francisco has sold to Essex Property Trust for an undisclosed sum. The vintage concrete tower is located at 1390 Market Street. The building also contains 13 floors of office space, a 399-car underground garage and an attached two-story retail building that houses Starbucks and other retailers. The residential units are situated on floors 14 through 29. Archstone acquired the entire tower in 2005 for $147.5 million. It sold the 232,000-square-foot office/retail component to Broadreach Capital for $42.7 million in 2007. Broadreach still owns that component. The recent sale was executed by David Orozco of Cassidy Turley and Frank Wheeler of Colliers International.
