A "non-essential group event" is defined as a gathering of 50 people for social, cultural, or entertainment events "where people are not separated by physical space of at least four feet," or about arm's length, according to NBC Bay Area.
The facilities affected by the order include City Hall, the San Francisco Public Library, the Palace of Fine Arts Theatre, and Moscone Center, a venue in the city's SOMA district where many tech conferences are usually held. Symphony events and ballet performances are among the events being canceled, and the city's upcoming St. Patrick's Day Parade has been postponed.
While events are being canceled, these venues are still allowed to remain open.
