According to J.K. Dineen at the SF Chronicle:

With five months to go before a Sept. 15 deadline to pull permits for the work, owners of nearly 52 percent of “tier three” buildings — wood-frame structures of between five and 15 units — have yet to submit permit applications. That’s the first step in the process needed to comply with the city’s 2013 mandatory soft-story law, which targets buildings susceptible to collapse in an earthquake.

Out of 3,526 buildings in the category, 1,693 have filed for permits, while 1,834 have not, said Department of Building Inspection Director Tom Hui. Hui said he is surprised at how many property owners have ignored the call to bring their buildings into compliance, given the monthly mailed notices and publicity around the program.

“They have had plenty of time to respond,” Hui said. “It’s for public safety. We just want them to comply and protect themselves, the tenant and the public. Earthquakes are not predictable — one could happen this afternoon.”

The clock is ticking!
