San Francisco Bay Conservation and Development Commission executive director Larry Goldzband said Monday that his agency received multiple complaints about the construction of the floating, four-story building.
Preliminary planning documents submitted to the port last fall showed plans for Google to build an interactive space for people to learn about technology.
It had been speculated that the barge would be a party boat or store for Google to sell its Internet-connected glasses.
Goldzband says the construction was not authorized by the agency, and the Treasure Island Development Authority which allowed the project could face fines and enforcement proceedings.
Goldzband says Google can resolve the issue by moving the barge to one of the fully permitted construction facilities in the San Francisco Bay.
