(03-09) 13:16 PST SAN FRANCISCO (AP) — City Hall may have a robot staying in its historic chambers after all.

Supervisors voted 7-2 Monday to negotiate renting out the grand legislative chamber to Walt Disney Pictures for a scene in the upcoming Robin Williams film, "Bicentennial Man."

City Architect Tony Irons earlier worried about letting crews film in the Manchurian oak-lined chamber.

But he changed his mind after Supervisor Michael Yaki introduced strict guidelines that include having a preservationist oversee the filming; making producers post a bond as a security deposit for damage; and banning fireworks, food, drinks, animals, smoking and fogging devices.

Supervisors Tom Ammiano and Leland Yee opposed allowing filming.

Disney has asked for five days this spring for a scene in the futuristic film starring Williams as a robot with human feelings.

The proposed fee: $10,000 for the first day of filming and $20,000 for each additional day.

The Board of Supervisors' final vote is scheduled for March 22 after contract negotiations. The 84-year-old City Hall recently was reopened after years of seismic retrofitting and renovation in the wake of the Loma Prieta earthquake of 1989.
