Soft Story Retrofit in Los Angeles: The Average Construction Costs

Soft Story Retrofit in Los Angeles: The Average Construction Costs

One of the most common questions we get during a site assessment is how much will a soft story retrofit process cost? Let’s dive into that today.

When the mandatory soft story retrofit program in Los Angeles became an ordinance (Ordinance 183893) in October 2015, it was difficult to calculate the construction costs. But ever since then, more than 1,000 multistory properties have been retrofitted in LA, which has made it easier to determine the costs.

This short article will give you an idea of how much you may need to pay for your seismic retrofit project. We have segmented the estimated construction expenses into different categories for your benefit.

You should also keep in mind that these are average estimations and every building is different. The figures below will help you understand the standard price points of retrofitting jobs in LA but they are not definite. Based upon the size of your property, location, engineering and construction methods, the actual price may vary.

That being said, let’s see how much a seismic soft story retrofit process may cost for your soft-story building in the city of Los Angeles.
