Google must move its mystery barge from a construction site on an island in the middle of the San Francisco Bay because the permits are not in order, a state official said Monday. The notice came after the San Francisco Bay Conservation and Development Commission investigated amid numerous complaints about the construction of the floating, four-story building, commission executive director Larry Goldzband said. The investigation found that neither the Treasure Island Development Authority nor the city of San Francisco had applied for required permits for the work to be done at the site. Goldzband said Google can resolve the issue by moving the barge to one of the fully permitted construction facilities in the San Francisco Bay. “It needs to move,” he said. Google did not immediately respond to requests for comment.
