Los Angeles is one of the most seismically active cities in the world, making earthquake preparedness a top priority for property owners. Soft story buildings—those with weak or open ground floors—are particularly vulnerable to seismic activity, putting residents, tenants, and investments at serious risk. The City of Los Angeles has mandated retrofitting for these structures to enhance public safety and prevent catastrophic building failures.
At Alpha Structural, we specialize in comprehensive soft story retrofitting, offering tailored solutions that meet compliance requirements while ensuring long-term structural stability. With decades of experience in seismic retrofitting and foundation repair, we provide property owners with expert guidance, cost-effective engineering, and seamless execution from start to finish. If your building falls under the city’s retrofitting ordinance, now is the time to take action. Strengthen your property before the next earthquake strikes.
What are Soft Story Buildings? A soft story building is a multi-story structure built with a first floor that is much less rigid (soft) than the floors above, such as in an apartment with tuck under parking. They can and have failed in significant seismic activity due to unreinforced openings on the ground floor which caused far more movement than the soft story building could withstand, resulting in the upper floors COLLAPSING on top of it. The Los Angeles Soft-Story Retrofit Program has begun to help prevent this from occurring in the future.
There are an estimated 13,500 soft story structures in Los Angeles alone that have been identified to be in need of a retrofit. Retrofitting soft story buildings has now become mandatory by the City of Los Angeles as of November 22, 2015.
In November of 2015, the City of Los Angeles signed into law, the Mandatory Retrofit Program under Ordinance 183893, requiring the retrofitting of wood-frame apartment buildings to better withstand a major earthquake. Structures that are in danger of being catastrophically damaged in the event of an earthquake are to be upgraded within a finite amount of time. This includes soft story retrofitting in Los Angeles county buildings. Los Angeles now has the nation's toughest earthquake safety rules.
From the Los Angeles Times:
“Under the law, property owners will have seven years to fix wood apartments and 25 years to fix concrete buildings. The city has already identified about 13,500 apartment complexes that officials suspect need repairs. A Times investigation in 2013 found more than 1,000 older concrete structures — including landmark buildings in downtown, Hollywood and Westwood — that require close scrutiny for retrofitting.”
Many more cities in the region are following suit and mandating the same soft story retrofit Los Angeles has signed into law. This is in an effort to avoid devastation and to safeguard residents from harm that has been caused by large earthquakes such as the Northridge quake in 1994.
In response to the seismic risks posed by soft story structures Los Angeles enacted mandatory retrofitting laws to ensure the safety of residents and property owners. The goal of this initiative is to reinforce vulnerable structures to withstand earthquakes, reducing the likelihood of catastrophic failures. Property owners must comply with these regulations to avoid penalties and protect their buildings from severe damage.

Listen NowIt is no longer an argument as to whether or not an earthquake of significant magnitude is going to strike Southern California - it’s now just a wait to find out WHEN. The longer your building doesn’t get its soft story retrofit in Los Angeles, the more likely something disastrous could occur.
There is no doubt that an unreinforced building could collapse, causing irrevocable damage to the structure - and those who reside in it. But did you know that you could be held liable for these catastrophes? There are multiple instances of property and bodily damage stemming from an earthquake resulting in the property owner getting sued for seven-digit figures.
Getting your building the soft story retrofitting Los Angeles structures need is not only a great idea which could save lives, your building and a costly lawsuit, but did you know that it could also lower your insurance premium? Not only that, there are grants, tax breaks and financial aid that you can apply for to assist you to safeguard your building. Not to mention that you could have your tenants help you pay for these repairs - up to 50%!
Los Angeles City Ordinance 183893, enacted in 2015, mandates seismic retrofitting for wood-frame soft story buildings constructed before 1978. The ordinance identifies over 13,500 buildings that require retrofitting, setting strict timelines for compliance:
Failure to comply can result in fines and legal consequences, as well as increased liability for property owners.
Enhanced Safety:
Strengthens the structural integrity of buildings, protecting residents and tenants.
Legal Compliance
Ensures adherence to local ordinances, preventing fines and legal action.
Insurance Savings
Many insurance providers offer reduced premiums for retrofitted buildings.
Financial Assistance
Property owners may qualify for grants, tax credits, and cost-sharing programs.
Increased Property Value
Buildings that meet modern seismic standards are more attractive to buyers and tenants.
A structural engineer evaluates the building’s vulnerabilities.
Custom retrofitting solutions are developed based on the building’s needs.
Necessary permits are acquired to comply with city regulations.
Reinforcements such as steel frames and shear walls are installed.

The City of Los Angeles has identified thousands of buildings that require mandatory retrofitting. Property owners can check the Los Angeles Soft Story Retrofit Property List using the city’s online interactive map to determine whether their building is affected. Early compliance helps avoid penalties and ensures timely retrofitting.
Several programs are available to assist property owners with the costs of seismic retrofitting:
Alpha Structural can guide property owners through the financial assistance process to minimize out-of-pocket costs.
