Seismic Retrofit Services

in San Francisco

California's earthquake risk makes seismic retrofitting one of the most important investments a homeowner can make. Older homes that were built before modern seismic building codes may be vulnerable to structural damage during an earthquake. At ADCON, we provide professional seismic retrofit solutions that strengthen your home's structural integrity and help improve its performance during seismic events.

With over 40 years of construction experience, our team understands San Francisco's building codes, permitting requirements, and the unique structural challenges of older homes. We work closely with homeowners, architects, and structural engineers to provide code-compliant seismic upgrades designed for long-term safety and durability.

Why Seismic Retrofitting

Matters

Many homes throughout San Francisco were built decades before today's seismic design standards. Without proper reinforcement, an earthquake can cause:

Foundation movement
Structural framing damage
Cripple wall failure
House shifting off its foundation
Floor settlement
Wall cracking
Roof movement
Significant structural damage

A properly designed seismic retrofit can greatly improve your home's ability to withstand earthquake forces while protecting your family and investment.

Previous earthquake damage

Our experienced team can evaluate your property and recommend the appropriate retrofit solution.

Seismic Retrofit Solutions We

Provide

Foundation Bolting

Anchor bolts secure the home's framing to the concrete foundation, helping reduce movement during an earthquake.

Cripple Wall Bracing

Many older San Francisco homes have cripple walls that require plywood bracing to improve lateral strength.

Shear Walls

Shear walls improve your home's resistance to horizontal earthquake forces and increase structural stability.

Soft Story Retrofit

Homes with large garage openings or open lower levels may require structural reinforcement to reduce collapse risk during an earthquake.

Structural Reinforcement

Additional framing, steel members, connectors, and engineered hardware strengthen critical structural components.
