Gay City formed in 1995 during the HIV/AIDS epidemic.
In the mid-2000s, Gay City introduced a Wellness Center that provided HIV testing and STI screening (syphilis, chlamydia, gonorrhea, and hepatitis C).[2] The health services expanded in 2019 to five locations. According to their website, Gay City is the leading HIV/STI tester in King County.[3]
The LGBTQ library was formerly held by the Seattle LGBT Community Center until it closed in 2009 and moved to Gay City.[5] It is called the Michael C. Weidemann LGBTQ+ Library and has over 8,000 books.[6][7]
In April 2022, Gay City moved into a new headquarters building at 400 E. Pine Street in the Capitol Hill neighborhood.[6][8]
