MANDATORY SOFT-STORY SEISMIC RETROFIT PROGRAM

First to adopt the mandatory Soft-Story Seismic Retrofit Program was the City of San Francisco via ordinance 66-13 in April 2013. 

The structures being evaluated by the city for the mandatory Soft-Story Seismic Retrofit Program compliance have the following characteristics:

  • Wood-frame construction
  • Ground floor contains a weak design with un-reinforced large opening for parking or similar.
  • Permit for original construction issued prior to January 1, 1978
  • Two or more stories.
  • Five or more unit buildings.

In an effort to prioritize the risk of damage by load occupancy, the city established a 4 tier system. The triggers for the completion of the Seismic Retrofit Program are based on the notification letter sent to the owners of each Soft-Story property. Phases of the Soft-Story Seismic Retrofit Program are outlined below.
