Mold has forced seven gay groups out of a subsidized building in Southern California.

The 301 University Building in the diverse Hillcrest neighborhood of San Diego housed seven gay groups, including Equality California, Marriage Equality USA, the Courage Campaign, San Diego Alliance for Marriage Equality and Restore Equality 2010, before a rising mold problem aggravated by torrential November rains pushed everyone out.

Californians Against Hate had just moved into the building when they were asked to vacate the premises.

“We found out that the rain damage from the previous weekend's storm caused severe water damage and more mold problems, so everyone was asked to vacate ASAP,” Californians Against Hate founder Fred Karger told On Top Magazine in an email. “We all complied.”

The building – being leased for a dollar a month – was “a space to share ideas,” he added. “We were thrilled to share office space with several more established organizations like Equality California and so many of the young, bright, enthusiastic new [gay rights] activists.”

Karger founded Californians Against Hate last year to organize boycotts against large donors to Proposition 8, California's voter-approved gay marriage ban.

“We wanted an office to be able to work more on our two remaining boycotts: Manchester Hotels and A-1 Self Storage,” Karger said. “We have a demonstration set up for January 9 at the Manchester Hyatt to protest the American Historical Association conference there, and more plans in the works.”

The groups say it is unlikely they'll find a similar property, but remain committed to the collaboration the building once fostered.

“We're still going to work together, and we will continue to build a community wide effort to win marriage back,” Jacqueline Palmer, field manager for Equality California, told the San Diego-based gay weekly Gay & Lesbian Times.

Karger, who now works from a virtual office, said he believed the building was slated to be torn down.
