Seismic Retrofit Services: Protect your home in San Francisco
Living in San Francisco means enjoying breathtaking views, a vibrant culture, and a strong sense of community. However, it also means preparing for the inevitable: earthquakes. The city is located in one of the most seismically active regions in the world, making earthquake preparedness essential for homeowners. At Behan Builders, we specialize in seismic retrofit services, ensuring your home is structurally sound and protected against seismic activity.
What Is a Seismic Retrofit?
A seismic retrofit is the process of strengthening a home’s foundation and structure to withstand earthquakes. Many older homes in San Francisco lack modern seismic codes, making them vulnerable to damage or collapse during a strong earthquake. Retrofitting enhances your home’s stability by reinforcing weak points such as foundations, cripple walls, and anchoring systems.

Why Seismic Retrofitting Is Essential in San Francisco
San Francisco sits along the San Andreas Fault and the Hayward Fault, both capable of producing major earthquakes. Scientists predict that the region will experience a large earthquake within the next 30 years, making ensuring your home is prepared more important than ever. A seismic retrofit significantly reduces the risk of structural failure during an earthquake, protecting your home, your investment, and—most importantly—your loved ones.
The Risks of an Unretrofitted Home
Without proper reinforcement, homes are susceptible to:
- Foundation failure – Homes can shift off their foundation, causing significant structural damage.
- Wall collapse – Weak or unbraced cripple walls can collapse, leading to costly repairs.
- Unsafe living conditions – Damage from an earthquake can render a home uninhabitable.
Retrofitting provides peace of mind, ensuring that your home remains standing and structurally sound after a seismic event.
Our Seismic Retrofit Process
At Behan Builders, we follow a meticulous process to reinforce your home’s structure while adhering to local seismic building codes. Our approach includes:
1. Inspection & Assessment
We begin by comprehensively evaluating your home’s foundation and framing to identify vulnerabilities. Our experts assess factors such as anchoring, cripple wall bracing, and foundation strength.
2. Custom Retrofit Plan
Every home is unique, so we design a customized retrofit plan based on your home’s structure and risk factors.
3. Foundation Bolting & Anchoring
One of the most critical steps in retrofitting is bolting your home to its foundation. We install high-strength anchor bolts and brackets to prevent your home from shifting or sliding during an earthquake.
4. Cripple Wall Bracing
Cripple walls—short wood-framed walls between the foundation and the first floor—are often the weakest point of a home’s structure. We reinforce these walls with structural plywood sheathing to strengthen and stabilize them.
5. Soft Story Reinforcement
If your home has a garage or an open lower level, it may be at higher risk of collapse during an earthquake. We install steel moment frames, bracing systems, and reinforced shear walls to prevent structural failure.
