Seismic retrofitting is a change or modification to an existing structure to make the building more resistant to seismic activity and lateral force.
A soft-story building is a multi-story building that has windows, wide doors, large unobstructed commercial spaces, and other opening in places where shear wall would be required for stability as a matter of earthquake engineering design.
Ordinance #183893 was put into place to reduce structural deficiencies. The buildings that comply with the ordinance can be subjected to structural failure during or after an earthquake. A very similar ordinance was passed in San Francisco in 2013 in response to the 1989 earthquake where numerous soft-story buildings collapsed because they were not designed to withstand the shear (lateral) force of the earthquake.

On average, structural plans can take up to 60 days. However, we work hard to deliver ahead of schedule.
The city typically takes between 6-8 weeks to approve and issue a permit to begin construction.
Construction starts as soon as the building owner gives the green light to begin.
Construction typically takes between 10 days and a month to complete.
Tenants can remain in the unit while the renovation work is done as long as the work does not make the home uninhabitable outside construction hours, and will not expose the tenant to toxic or hazardous materials. More information can be found on the HCIDLA website.
There are several ways to retrofit a soft-story building depending on the scope of work. Installing moment frames, shear walls, and cantilever columns are some of the common methods used to retrofit a building. Call today to speak to one of our experts to find out more.
The THP describes what kind of work the landlord is going to do, how the work will affect the tenant, and how long the work will take. The landlord must submit this plan to the HCIDLA before any work may begin. We prepare the THP and all ancillary documents for you. For more information click here
