The Grand Hyatt San Francisco is a skyscraper hotel located half a block north of Union Square in San Francisco, California. The 36-storey, 660 room 108 m tower was completed in 1972, as the Hyatt on Union Square and renamed the Grand Hyatt San Francisco in 1990. The hotel had 402 employees before the COVID-19 pandemic, dropping to 28 as of April 2021, mainly due to cancelled conventions in the city. It was closed for around half of 2020, losing about $1 million per day during that time.
