Completely rebuilt in 2008, the academy's primary building in Golden Gate Park covers 400,000 square feet (37,000 m⁲). In early 2020, before the COVID-19 pandemic, the California Academy of Sciences had around 500 employees and an annual revenue of about $33 million. The museum is accessible via public transit on the N Judah Metro line. The westbound 9th Avenue and Irving station is located about 0.5 miles from the Academy of Sciences. Three Muni bus lines also serve the museum, including the 44, 5, and 7 lines.
