Why Earthquake Retrofitting Matters in San Francisco, California

San Francisco’s position near the San Andreas Fault has exposed it to significant seismic activity throughout history, including the devastating 1906 earthquake that caused widespread destruction. With thousands of multi-unit soft-story buildings in the city, many constructed before modern seismic codes, retrofitting is crucial to prevent similar tragedies in the future. 

These buildings, defined as wood-frame structures with five or more residential units and weak ground-floor walls, face a heightened risk of collapse during a major quake. To address this, San Francisco’s Soft Story Retrofit Ordinance was signed into law in April 2013, requiring affected properties to undergo seismic strengthening. This phased program ensures the most vulnerable buildings are retrofitted first, contributing to a safer San Francisco.

These updates help protect your San Francisco property and its occupants from seismic damage.

Earthquake Retrofitting

Earthquake retrofitting in San Francisco strengthens the connection between your house or soft-story building and its foundation to reduce the risk of shifting or separation during seismic events. Our San Francisco contractors specialize in bolt retrofit techniques, using anchor bolts and other proven methods to reinforce weak points. These modifications enhance your building’s resilience, ensuring it is better prepared to withstand future earthquakes.

Soft-Story Retrofitting

Buildings with open ground floors, such as those used for parking or commercial spaces, are highly vulnerable during an earthquake. Our team addresses this risk by installing steel moment frames, shear walls, and other reinforcements to strengthen the structure. These soft-story retrofitting updates improve safety and ensure compliance with San Francisco’s mandatory retrofit ordinance.

Earthquake Brace & Bolting

To stabilize your building’s foundation, we use bracing and bolting techniques that secure the frame to the foundation. Our retrofit contractors install steel anchors and braces to reinforce the structure and prevent foundation displacement. This helps keep your property intact during seismic activity, providing lasting peace of mind.
