Full Service Engineering and Construction in Los Angeles

As seen posted by the LADBS, the City of Los Angeles passed Ordinance 183893, which requires the retrofit of pre-1978 wood-frame soft-story buildings and non-ductile concrete buildings. The goal of the mandatory seismic retrofit ordinance is to reduce these structural shortfalls and improve the safety of the flagged buildings during earthquakes in Southern California. Deprived of retrofitting, the weak buildings may be exposed to major structural damage. See how apartments can collapse during an earthquake in this LA Times infographic.

Buildings that are most vulnerable have been identified with the following conditions:

  • Consist of 2 or more stories wood frame construction
  • Built under building code standards enacted before January 1, 1978
  • Contain ground floor parking or other similar open floor space

The program does not apply to residential buildings with 3 or less units.

More information can be found in the following articles:

Each property owner of the flagged buildings will be sent an order to comply. These orders have already started to go out and will continue to be mailed into May 2017.
