Managing Risk of Collapse-Prone Buildings in California

California’s 14 million buildings include some of the most modern and earthquake-resistant in the world. However, older buildings could be damaged and a few – perhaps less than 5% – could collapse in severe shaking. This amount may seem small, but collapse can cause significant life loss, injuries and substantial social and economic disruption mounting to hundreds of billions of dollars. The “Guide to Identify & Manage Seismic Risks of Collapse-Prone Buildings” summarizes California’s laws and regulations to help local governments identify and reduce collapse risks, as well as best practices that building owners can take to manage the risks.

The SSC published this Guide and a companion Appendix in March 2017.
