As San Francisco enters into a condo construction boom reminiscent of that before the 2008 crash, new condos are grabbing premiums of up to $400 per square foot over their older condo neighbors. The divide is particularly stark in Potrero Hill, where older condos built before 2007 receive $722 per square on average, while the new Onyx building is reaching a heady $1,135 per square. In Hayes Valley, Duboce Triangle, the Inner Richmond and Nob Hill premiums for new condo construction are all more than $200 per square when compared to their pre-2007 counterparts that are being resold.
