Los Angeles Soft Story Retrofit Experts — Helping Owners Comply with Mandatory Codes and Strengthen Vulnerable Buildings.
Many multi-unit and mixed-use buildings in Los Angeles were built with open ground floors for parking or storefronts. While convenient, these designs leave structures dangerously vulnerable during earthquakes.
After past seismic events revealed widespread structural failures, the City of Los Angeles adopted mandatory soft story retrofit ordinances to reduce the risk of collapse, injury, and loss of life.
If your building qualifies, taking action isn’t optional — but navigating the process doesn’t have to be overwhelming.
A soft story building is one where the ground floor is significantly weaker than the upper levels — most commonly because open space was left for parking, garages, or large retail openings. In an earthquake, this imbalance can cause the first floor to shift or collapse while the upper floors remain intact.
Many buildings in Los Angeles were built this way long before modern seismic standards. That means if your property has an open first floor with limited structural support, it may be at risk — even if it feels perfectly normal today.
Identifying a soft story building is the first step toward protecting your property, tenants, and investment before the next major quake.
• Pre-1978 wood-frame construction
• Open or minimally reinforced first level
• Multi-unit apartments or mixed-use buildings
In Los Angeles, many soft story buildings are subject to mandatory seismic retrofit requirements adopted after past earthquakes exposed widespread structural failures.
If your property was built before modern seismic standards and includes an open or weak ground floor, it may fall under the City’s soft story retrofit program. Owners of qualifying buildings are typically required to evaluate their structure, submit plans, and complete strengthening work within set timelines.
Missing deadlines or ignoring retrofit requirements can lead to penalties, enforcement actions, and increased liability — but determining whether your building qualifies isn’t always straightforward.
That’s where informed guidance makes the difference.
Navigating a soft story retrofit doesn’t have to be confusing or disruptive. Our process is designed to help Los Angeles property owners move forward with confidence — from understanding requirements to completing work efficiently and responsibly.
1. Initial Consultation & Building Review
We start by reviewing your building’s configuration, age, and use to determine whether it may fall under Los Angeles soft story retrofit requirements. This initial step helps clarify your situation before any commitments are made.
2. Evaluation & Retrofit Planning
If retrofit is required, we help coordinate the appropriate evaluations and outline retrofit options tailored to your building. Each approach considers structural needs, occupancy, access, and long-term impact.
3. Permitting & Compliance Support
Retrofit projects involve city review and approvals. We assist with navigating permitting requirements and timelines so the process moves forward efficiently and in alignment with local expectations.
4. Retrofit Construction & Installation
Once approvals are in place, retrofit work is performed using proven strengthening methods designed to improve lateral stability while minimizing disruption where possible.

Shear Walls & Reinforced Bracing
Anchoring & Bolting to Foundation
Note: Each retrofit is tailored based on building type, use, and compliance needs.
Soft story retrofit can feel overwhelming — especially when city requirements, timelines, and structural concerns all converge at once. Property owners choose Soft Story Advisors because we focus on clarity, communication, and responsible guidance at every step.
Advisory-First Approach
We help owners understand their obligations and options before pushing solutions. Our role is to guide, not pressure.
Los Angeles–Focused Experience
We work with the realities of LA buildings, ordinances, and permitting processes — not generic retrofit assumptions.
Clear Communication
From initial review through completion, we explain what’s happening, why it matters, and what comes next.
Property-Specific Solutions
No two buildings are the same. We account for structure type, occupancy, access, and long-term considerations.

Not all buildings qualify, but many do. Requirements depend on factors such as building type, construction era, and how the ground floor is configured. An initial review can help determine whether your property falls under the City’s retrofit program.
Buildings with open or weak ground floors — commonly used for parking or commercial space — and residential units above are often classified as soft story. Many older wood-frame buildings in Los Angeles fit this description, even if they appear structurally sound today.
Failing to comply may result in enforcement actions, penalties, and increased liability exposure. More importantly, unretrofitted buildings remain vulnerable during seismic events. Understanding your obligations early helps avoid unnecessary risk.
Yes. Part of our role is helping property owners navigate the permitting and approval process so projects move forward in alignment with local requirements and timelines.
Every building is different, but retrofit plans are typically developed with occupancy and access in mind. Clear planning helps reduce disruption and set realistic expectations for owners and tenants alike.
