File: The tour played four events before the COVID-19 pandemic forced a five-and-a-half month break.
The PGA of America said in a statement the first golf major of 2020 will take place at San Francisco's Harding Park from 6 to 9 August.
The tournament had been rescheduled to its August date after being postponed from its original slot in May because of the coronavirus pandemic.
The PGA of America formally confirmed the tournament would be held on Monday after weighing alternative options, which included moving the tournament to another course.
The decision to bar spectators from the event was taken out of consideration for "the health and well-being of all involved," the PGA said.
PGA officials had also awaited approval from California officials before pressing ahead with the schedule.
The decision comes after the PGA Tour has made a largely successful return from its COVID-19 shutdown, which forced the postponement or cancellation of all four golf majors this season.
The tour returned to tournament play earlier this month with the Charles Schwab Challenge at Colonial Country Club in Texas followed by last week's RBC Heritage at Hilton Head Island, South Carolina.
Both events took place without spectators while players have observed strict safety protocols which include frequent testing for COVID-19.
