Soft-Story Buildings in San Jose: Why Owners Are Retrofitting Now

December 26, 2025

Soft-story buildings in San Jose have become a focal point for safety concerns due to their vulnerability during seismic events. Owners are increasingly choosing to retrofit these structures to enhance safety and comply with local regulations. Understanding what soft-story buildings are, the risks they pose, and why retrofitting is crucial can help property owners make informed decisions.

Understanding Soft-Story Buildings

What is a Soft-Story Building?

A soft-story building has one or more floors with large openings and less structural support than the floors above, often found in parking areas, large windows, or commercial spaces on the ground floors. This architectural feature, while aesthetically pleasing and functional, can jeopardize the building's structural integrity during an earthquake.

The Soft Story Collapse Risk

Soft-story buildings are notorious for their collapse risk during seismic activities. These structures are less able to withstand the lateral forces caused by ground movement during an earthquake, which can lead to significant damage or total collapse. The tragic consequences observed in past earthquakes, including loss of life and property, underscore the importance of addressing these vulnerabilities promptly.

San Jose's Seismic Risks

San Jose sits within one of the most earthquake-prone regions in the United States. The San Jose seismic risk is intensified by the proximity to major fault lines such as the San Andreas and the Hayward Faults. This heightened risk mandates stringent safety measures for buildings, particularly soft-story structures, to protect against potential earthquakes.

Importance of Retrofitting Soft-Story Buildings

Seismic Retrofit Urgency

The urgency for seismic retrofitting stems from the need to protect buildings and their occupancies during seismic events, minimizing the risk of collapse. Retrofitting involves structural enhancements that improve the building's resilience against earthquakes, such as strengthening weak first stories and enhancing the overall structural framework.

Building Safety Upgrades

Retrofitting not only addresses seismic safety but also significantly upgrades the overall building safety. Ensuring that a building can withstand an earthquake is crucial for the safety of the residents and for protecting the owner's investment. Furthermore, retrofitting can lead to savings in insurance costs and increase property values, providing economic incentives for building owners.
