Los Angeles – Seismic Retrofit News

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.

Santa Monica – Seismic Retrofit News

The Santa Monica seismic retrofit ordinance is currently in the 30-day petition period. The 2nd reading of the ordinance will be held on March 28th, and can potentially be in effect on April 1st. Upon the completion of the 30-days from the 2nd reading, the notices may be sent out.

The Santa Monica rent control board still has yet to make a decision on the amount of cost that owners are allowed to pass through to the tenants.

Based on the proposed noticing schedule (below), unreinforced masonry (“URM”) buildings are first in line. This would include any building with at least one unreinforced masonry bearing wall. The owners of these URM buildings will have 3 months from the date the notice was sent to have structural analysis performed on their buildings. This must be performed by a certified structural engineer/architect. The City of Santa Monica Planning and Community Development Building and Safety department is anticipating a surge in permit applications, which may affect the time it takes for application approval.

An address search on buildings that fall under the ordinance is available on the City of Santa Monica’s website.
