Soft-Story Hazard Mitigation - Preventive Action

Following the collapse of many soft-story buildings in the 1989 Loma Prieta and 1994 Northridge earthquakes, many cities realized the need to identify the numbers, locations and conditions of these seismically vulnerable buildings.

Soft-Story Ordinances

Several Bay Area cities have taken the initiative to inventory their soft-story apartment buildings in order to understand their vulnerable characteristics and formulate policies that promote strengthening by owners.


If you have received a notice that your soft-story building requires a seismic assessment report or a seismic retrofit contact a structural engineer to provide you with all of the documentation that you need to comply with the notice.
