MANDATORY SOFT-STORY PROGRAM

City of Los Angeles initiated The Mandatory Soft-Story Seismic Retrofit Program by adopting ordinance 183893 on November 22, 2015. Further updates in ordinance 184081 including time limits were adopted on February 12, 2016. The program has identified over 13,000 buildings which may be defined as a Soft-Story structure with compliance requirements for Seismic retrofitting. The following building characteristics determine the type of structure the city is looking to comply with the seismic retrofit requirements:

  • Wood-frame construction
  • Construction permit was applied for prior to January 1, 1978
  • Four or more dwelling units
  • Ground floor containing parking or similar open floor or basement space causing soft, weak, or open lines where there exists at least one or more levels above

The program oversight has been assigned to the Los Angeles Department of Building and Safety (LADBS). The timeline for compliance is based on an order/notification from LADBS.

The triggers for the 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.
