Burbank Soft-Story Seismic Retrofit
Effective January 10, 2025
The City of Burbank, CA has implemented a mandatory soft-story retrofit ordinance requiring seismic upgrades for certain vulnerable buildings. Structures subject to this ordinance typically meet the following criteria:
Wood-frame construction with two or more stories
Built under building codes adopted before January 1, 1978
Feature a weak or flexible first story, often with large openings along the perimeter—such as garages or tuck-under parking areas
This ordinance aims to enhance public safety by reinforcing these at-risk buildings and improving their resilience during seismic events.

Maintain structural integrity and achieve regulatory compliance with our precision-engineered seismic retrofit solutions. Our team specializes in soft-story and non-ductile concrete retrofits, addressing structural vulnerabilities identified under local seismic ordinances. We manage the entire process—from structural assessments and code-compliant design to permit acquisition and construction execution—ensuring minimal disruption and maximum protection for occupants and assets in high-risk seismic zones throughout Southern California.
The Retrofitting Process
Initial Assessment: A licensed structural engineer conducts a detailed evaluation to identify seismic vulnerabilities in the building.
Engineering & Design: Tailored retrofit plans are developed, incorporating structural solutions specific to the building’s condition and code requirements.
Permitting: All required permits are secured to ensure full compliance with local seismic retrofit ordinances.
Construction: Structural reinforcements—such as steel moment frames, shear walls, and anchorage systems—are installed to enhance seismic resilience.
Final Inspection & Certification: A city inspector reviews the completed work to verify adherence to seismic safety standards and formally approves the retrofit.
Common Retrofitting Methods
Steel Moment Frames: Rigid structural frames engineered to absorb and resist lateral seismic forces, preserving the building’s usability and layout.
Plywood Shear Walls: Reinforcements added to existing walls to improve lateral load distribution and enhance overall structural stability.
Cantilevered Column Systems: Engineered columns and elements that increase structural strength while maintaining open floor plans and usable space.
Foundation Bolting & Anchoring: Secure connections between the building’s wood framing and concrete foundation to prevent displacement during seismic activity.
