Thousands of San Francisco buildings may be at risk of severe earthquake damage

Thousands of San Francisco buildings, including famous historic sites, low-income apartments and Twitter’s headquarters reportedly may be at risk of severe earthquake damage. The buildings appear on a previously unpublished draft list of 3,407 concrete buildings in San Francisco that may be at high risk of collapse in a major earthquake, according to a city government document obtained by NBC News through a public records request.
The building list, which NBC News is publishing for the first time, provides a window into the sweeping cross section of San Francisco that could be especially vulnerable in a high-magnitude earthquake. Retrofitting the buildings so that they’re deemed safe could require billions of dollars and decades of work, structural engineers said.
Thousands of people who live or work in the buildings could be taking on additional risk every time they step inside — and many of them likely don’t know their buildings are on the list because the city hasn’t decided when it will send out official notices.
Contact Optimum Seismic if you have concerns about the structural safety of your buildings.
