Retrofitting Inspections
We start with a detailed on-site inspection of your property. Our licensed inspectors evaluate the foundation, framing, cripple walls, and other structural components to identify vulnerabilities unique to San Francisco’s building stock.
Seismic Retrofitting
Beyond soft-story vulnerabilities, we strengthen entire structures by reinforcing shear walls, adding bracing systems, and distributing seismic forces more evenly throughout the property.
Foundation Strengthening
A stable foundation is critical to every retrofit. We repair or reinforce existing foundations to ensure they can handle added structural loads and lateral forces during an earthquake.
Soft-Story Retrofitting
Soft-story buildings with open ground floors, often used for parking or commercial space, are highly vulnerable to collapse during a quake. We install steel moment frames, shear walls, and reinforcements to stabilize these structures and bring them into compliance with San Francisco’s retrofit ordinance.
Earthquake Brace & Bolting
Older buildings often lack proper connections between the frame and foundation. Our team installs steel anchor bolts and bracing systems to secure the building’s structure, reducing the risk of sliding or shifting during seismic activity.
Tenant Habitability Planning
During construction, we develop Tenant Habitability Plans that outline clear steps to minimize disruption while keeping tenants safely in place. Our team works closely with property management and local officials to comply with habitability requirements throughout the retrofitting process.
"The Retrofit1 team was incredibly professional and made the entire retrofitting process stress-free. I can finally sleep at night knowing my building is much safer."
Why Earthquake Retrofitting is Crucial in San Francisco
San Francisco faces constant seismic threats from the nearby San Andreas and Hayward Faults. Many older soft-story buildings, built before modern codes, remain vulnerable to collapse during major earthquakes.
Since 2013, the city’s Soft Story Retrofit Ordinance has required seismic upgrades for multi-unit buildings most at risk. This proactive measure helps protect both residents and property investments.
Key reasons to retrofit:
- Prevent life-threatening collapses
- Avoid costly structural repairs after a quake
- Reduce legal and financial liability
- Preserve property value
- Comply with San Francisco safety ordinances
We proudly serve San Francisco and nearby cities with similar seismic risks, including Oakland, Alameda, Berkeley, San Jose, and Fremont.
