The company has already signed a deal to move into the San Francisco Design Center, the anchor of the city's Design District "Showplace Square." Zoned for "production, distribution and repair" (PDR), the building serves as a showroom for many skilled trade companies—and currently has a 90 percent occupancy rate. But as property owners across the city enviously ogle at SoMa's high office rents, other neighborhoods are looking to cash in, city Supervisor Malia Cohen told the San Francisco Chronicle.

"The market is changing and the landlords are seeing dollar signs," Cohen said. "They want to push everyone out. That kind of displacement sickens me, and it's the kind of displacement that has San Francisco in a crisis."

Ordinarily a tech company couldn't move into a building zoned for PDR. However, SocketSitereports the landlord is having the building designated as a historic landmark, exploiting a loophole that allows historic structures to be rezoned for preservation purposes.

I'm still trying to understand that loophole.

Historic structures can be rezoned for use by Internet startups?! What the what??

And yes, San Francisco really is pushing non-rich people out, little by little.
