# Soft Story Retrofit Requirements in Los Angeles: What Every Property Owner Should Know

If you own a multi-unit residential building in Los Angeles, you’ve probably heard about seismic retrofit mandates—and for good reason. With the city sitting along a major fault line, the risk of earthquake damage is very real. In response, Los Angeles passed an ordinance requiring owners of certain structures to complete structural upgrades. At the heart of this effort is soft story retrofitting Los Angeles property owners are now required to complete.

But what exactly are the requirements? Who needs to comply? And what happens if you don’t? This guide breaks it all down so you know what to expect—and why this isn’t something you want to put off.

## What Is a Soft Story Building?

A soft story building is a multi-story structure with a ground floor that’s weaker or less rigid than the upper floors. This design is often seen in older apartment buildings where the first level includes open parking areas or large windows and doors. While this layout may offer convenience or visual appeal, it creates a structural vulnerability during earthquakes. Without proper reinforcement, the lower level is more likely to collapse under seismic pressure, making retrofitting a necessary safety measure.

## Why Los Angeles Enforced Retrofit Requirements

Following the devastation caused by previous California earthquakes—particularly the Northridge quake in 1994—engineers and city officials identified soft-story buildings as a major risk. As a result, the city introduced Ordinance 183893, requiring seismic retrofitting for certain types of older structures. The goal is to prevent future loss of life, reduce property damage, and increase citywide safety.

## Which Buildings Are Affected?

Not all properties are subject to this ordinance, but many are. If your building is a wood-frame structure with two or more stories, was built before January 1, 1978, and includes a soft, open, or tuck-under level (often used for parking), then it likely falls under the mandate. These types of buildings are common throughout Los Angeles, especially in older neighborhoods and areas with dense multi-unit housing.

## What Are the Retrofit Deadlines?

After receiving a notice from the city, building owners are placed on a multi-year timeline. Within the first year, you must submit engineering plans or proof of an existing retrofit. By year two, you’re required to pull a permit to begin the work. And by year seven, construction must be complete. These deadlines are strictly enforced, and the clock starts ticking from the moment the notice is delivered. Staying on schedule helps avoid unnecessary fines, delays, or legal complications.

## What Does the Retrofit Process Involve?

The exact scope of a retrofit depends on the building’s structure, but the overall goal is the same: reinforce the weak lower level to improve its seismic performance. This typically involves installing steel frames, shear walls, or anchoring the foundation. A structural engineer will assess the property and recommend the appropriate reinforcements. Though the construction may cause temporary disruption, the improvements are vital to protecting the building—and the lives inside it.

## What Happens If You Don’t Comply?

Failing to meet the retrofit requirements comes with serious consequences. Property owners could face escalating fines, legal action, and in some cases, orders to vacate or demolish unsafe buildings. Additionally, insurance companies may deny claims if a building is damaged in an earthquake and wasn’t brought up to code. For landlords, this could also mean lawsuits from tenants injured during a quake. In short, ignoring the ordinance puts your property, finances, and reputation at serious risk.

## Benefits of Completing a Retrofit

Although it requires an upfront investment, retrofitting delivers long-term benefits. First and foremost, it significantly improves tenant safety, which can lead to higher occupancy and lower turnover. It also makes your building more attractive to insurers, potentially lowering premiums. Over time, these upgrades can increase your property’s resale value and protect against much larger repair or liability costs in the event of a quake. When it comes to soft story retrofitting Los Angeles, the benefits far outweigh the risks of inaction.

## Final Thoughts: Don’t Delay the Retrofit

Los Angeles has made it clear: soft-story retrofits are not optional. If your building falls under the ordinance, now is the time to act. Completing the process may take time, but it's a decision that protects lives, ensures legal compliance, and safeguards your investment. The next big earthquake is not a question of if, but when. Preparing your building now through soft story retrofitting Los Angeles is not just smart—it’s essential.
