Frequently Asked Questions

What is a soft story retrofit?
A soft story retrofit is seismic strengthening for buildings with a weak ground floor, most often older wood-framed, multi-family, or mixed-use buildings with parking, tuck-under units, or large openings on the bottom level. The retrofit reinforces that level so the building can better withstand an earthquake. De Sisto Construction performs soft story retrofits across Los Angeles County.
Is my building required to have a soft story retrofit?
Many California cities have mandatory soft story retrofit ordinances, including Los Angeles under the Mandatory Soft Story Retrofit Program. Whether your specific building is required to retrofit depends on your city's ordinance and your building type. Call us at 562-425-1050 and we can help you determine where your property stands.
Do you handle the engineering, permitting, and construction?
Yes. We provide a turnkey process, from engineering and construction through permitting and compliance, so the entire retrofit is managed under one roof. We've run soft story retrofit work for developers and property management companies since launching our retrofit division in 2019.
