Homeowners are becoming increasingly concerned about earthquake hazards. Los Angeles recently announced its “Resilience by Design” program to upgrade buildings for future earthquakes, which will include a “building rating system.” The Oregon legislature is considering mandating that home inspectors report whether houses are vulnerable to earthquakes. The California Earthquake Authority will soon need inspectors to verify earthquake upgrades qualify for insurance rate reductions. Where will trained inspectors come from?

Attendees learn how earthquakes damage wood-framed buildings, what structural features are most vulnerable and effective strengthening measures. Since inspectors often find defective installations, common defects are also covered. The presentation includes many photos.
