The Folsom Street Fair and Up Your Alley Fair are migrating from their namesake South of Market thoroughfares to the virtual realm amid coronavirus concerns, producer Folsom Street Events announced Monday, April 27.

“​We feel it is the ethical and the responsible choice to make before fair planning and production proceeds any further,” Executive Director Angel Adeyoha said in a statement.​ “The safety and well-being of our attendees and community members are our top priority.”

Now in its 37th year, the Folsom Street Fair was founded during the AIDS crisis, and that legacy of activism and care for its community were a part of the decision to go online, organizers said.

The digital version of Up Your Alley Fair is scheduled to take place the weekend of July 26, and the Folsom Street Fair, the world’s largest leather and fetish festival, is set to go virtual the weekend of Sept. 27. Both events will feature DJs and live-streamed musical performances, online shopping, and demonstrations.

Folsom Street Events expects to announce more specific plans in the coming weeks.

In 2014, the most recent year for which data is available, approximately 200,000 people attended the Folsom Street Fair, 71% of whom came from outside the city, according to a report from San Francisco’s Office of Economic Analysis. That year, visitors generated more than $180 million for local businesses.
