The Mandatory Retrofitting Law in San Jose: What You Should Know
The City of San Jose requires many multi-family property owners to complete seismic retrofitting to improve safety and prevent major earthquake damage. If you receive a city notice, you’ll need to follow strict deadlines to bring your building up to code.
The law mainly affects “soft-story” buildings, like
- Apartments over carports
- Properties with wide ground-floor openings
Retrofitting strengthens these vulnerable structures, protecting both residents and your investment.

Retrofit1 offers professional earthquake retrofitting services to protect your building from seismic damage:
Soft-Story Retrofitting Solutions
We reinforce soft-story buildings with:

We use bracing and bolting to fasten your building to its foundation with seismic anchor bolts, steel connectors, and engineered bracing systems, preventing it from sliding off its base.
Foundation Repair
We repair and strengthen your building’s foundation to restore load-bearing capacity, repair cracks, and prepare the structure for seismic retrofitting.

Is Your San Jose Building Earthquake-Ready?
San Jose sits between the Calaveras and San Andreas fault lines, making it one of California’s highest-risk seismic zones. If your multifamily building was built before 1990, it may require mandatory seismic upgrades under the 2026 San Jose Soft-Story Ordinance.
These are some of the warning signs your property may be at risk:
- Built before 1990 with tuck-under parking or open ground floors
- Visible foundation cracks or sloping floors
- Unbraced walls or weak lateral support
- Located in a seismic hazard zone
Don’t wait for the next big one. Start planning now to stay ahead of deadlines and avoid penalties and contact us.
