Soft Story Retrofitting

Is your building part of the soft story retrofit project in Los Angeles?

Seismic earthquake activity invariably causes property owners to ask, “how safe is my building?” and “do I need seismic retrofitting?”  Large earthquakes in the greater Los Angeles area have shown that certain types of buildings are extremely vulnerable!  For example, structures that are not bolted to their foundations can slide off the foundation during an earthquake, buildings that have unreinforced masonry will see it crumble, and so-called “Soft Story” buildings are in danger of complete collapse.

SEISMIC RETROFITTING CAN SAVE YOUR SOFT STORY STRUCTURE 

Local government officials in the greater Los Angeles area have recently required property owners to prepare for the next big earthquake.  In 2016, many owners of “soft story” buildings received a notice from the City that they must earthquake retrofit their buildings.

Soft story buildings are typically multi-story structures that have one or more floors with large opening windows, wide doors, large unobstructed commercial spaces, or other openings in places where walls would normally be required for stability as a matter of earthquake engineering design.  Many such soft story apartment buildings a “tuck-under” parking garage structure.

Building such structures became popular in the 1940s and 50s, as the City of Los Angeles spread West toward the Pacific Ocean and North into the San Fernando Valley.  In fact, recent stories in the Los Angeles Times show that many of the largest and most vulnerable apartment buildings are right in the San Fernando Valley!

LA Times, “Is my building vulnerable in a big earthquake? Here’s how to find out” by Shelby Grad, July 9, 2019, available here: https://www.latimes.com/local/lanow/la-me-earthquake-building-vulnerability-20190709-story.html

Sadly, such soft story structures are susceptible to damage during seismic activity, as was seen in many news story reports during the infamous Loma Prieta earthquake of 1989 and the 1994 Northridge earthquake, which caused many such soft story buildings to collapse.

    LOS ANGELES SEISMIC RETROFITTING ORDINANCES

    In 2015, two city-wide ordinances were passed into, requiring the owners of soft story construction buildings to retrofit them in strict accordance with city retrofitting codes.   The purpose of the ordnances and the city’s mandatory retrofitting program was to reduce the potential risk of injury and loss of life and property that could result from seismic earthquake activity taking a toll on vulnerable soft story buildings.  Without strengthening and retrofitting the construction of such vulnerable buildings, structural failure can occur both during and/or after an earthquake.

    The City of Los Angeles Department of Building and Safety (“LADBS”) has identified buildings* that are most vulnerable to seismic activity, thus requiring a seismic retrofit, as having the following criteria:

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

    * Note that the LADBS Soft Story Retrofit Program does not apply to residential buildings with 3 or less units. Owners of larger residential units have orders to comply with the soft story ordinance.

    Soft story building retrofitting work is typically done in three phases:

    • Submitting a retrofit plan within 2 years
    • Obtaining a permit to begin construction or demolition within 3.5 years and
    • Completing the job within 7 years.

    Earthquake Retrofitting Los Angeles Ordinance 183893 and 184081

    The first City seismic retrofitting ordinance No. 183893, specifies the type of buildings required under the Los Angeles soft-story retrofit system to complete a seismic upgrade.  Built before 1978, this list includes wood-framed structures and soft-story buildings.  The second ordinance No. 184081, provides information regarding the deadline for building owners to complete their retrofit and comply with the compulsory system.  The second order has two components depending on whether you intend to retrofit or completely demolish the house.

    City officials compiled a list of all the buildings and structures that they consider as at risk and then sent a letter to the owners of these buildings, notifying them of the compulsory Los Angeles retrofit soft-story program.  The letters gave owners, in most cases, up to seven years to draft plans and complete the necessary retrofits.   If you are the owner of a soft story building and you received the City’s “notice to comply” but have not yet hired a soft story retrofitting Los Angeles contractor at this point, you probably should have!  But don’t worry, keep reading, as the earthquake retrofitting professionals at Weinstein Construction are here to answer all your questions and make it simple for you to understand the process.
