Earthquake Retrofitting in Santa Clara County, California
Securing Your Property, Ensuring Your Safety
Santa Clara County straddles the Calaveras and San Andreas fault systems, making earthquake retrofitting essential for multifamily buildings from Sunnyvale to Palo Alto. If your property was constructed before 1990, and especially those with tuck-under parking or open ground floors, local soft-story ordinances already in place in San Jose and other county cities may require mandatory upgrades.
Signs your building may need retrofitting:
- Pre-1990 construction with carports or large window walls
- Visible foundation cracks, sloping floors, or sticking doors
- Unbraced cripple walls or weak lateral supports
- Location within a mapped seismic hazard zone
Don’t let deadlines or fines catch you off guard. Connect with Retrofit1 today to create a tailored earthquake retrofitting plan for your Santa Clara property, lock in contractor availability, and safeguard your investment before the next big shake.

Mandatory Soft-Story Ordinances Throughout the County
Property owners across Santa Clara County face increasing regulatory pressure to retrofit vulnerable multifamily buildings. San Jose’s mandatory soft-story retrofit ordinance, effective April 2026, applies to wood-frame buildings with at least three residential units built before 1990. Mountain View has surveyed multi-family dwellings to assess structural weaknesses, and additional cities are implementing similar requirements.
Compliance Deadlines Are Approaching
Ordinances typically establish tiered timelines based on building size and occupancy. Property owners must complete seismic assessments, obtain engineering reports, secure permits, and finish construction within specified periods. Non-compliance can result in substantial fines, legal liability, and restrictions on property transactions.
Tenant Habitability Requirements
Retrofitting occupied buildings requires careful coordination to maintain habitability throughout construction. Tenant Habitability Plans (THP) must address noise mitigation, dust control, temporary relocations, and communication protocols. Our team manages all THP requirements, ensuring compliance while minimizing tenant disruption and preserving rental income.
From Inspection to Installation: Safeguarding County Structures
Retrofit1 delivers professional earthquake retrofitting throughout Santa Clara County, customizing every project to address each building’s vulnerabilities. Our engineers start with a detailed seismic assessment, then design cost-effective reinforcement plans that satisfy building codes while minimizing tenant disruption and preserving property operations.
Detailed Seismic Inspections
Our engineers survey foundations, framing, and load-bearing walls to identify cracks, loose connections, and soft-story openings. We determine exact retrofit requirements and verify whether local ordinances mandate upgrades for your property.
Advanced Retrofitting Techniques
We install shear walls, steel braces, and foundation anchors that redistribute seismic forces through the building frame, preventing lateral collapse and meeting current code requirements for properties from Gilroy to Los Gatos.
Reinforcing Soft-Story Structures
Buildings with open ground floors are particularly susceptible to collapse in a major earthquake. Our soft-story retrofitting services include installing steel moment frames, shear walls, and additional supports to reinforce weak structural points.
Earthquake Brace and Bolting Services
Bracing and bolting anchors your structure to its foundation with high-strength bolts and cripple-wall bracing, sharply reducing quake movement. Our code-compliant installations provide critical protection for multifamily properties throughout Sunnyvale, Milpitas, and Cupertino

Our Retrofitting Process for Commercial Properties
At Retrofit1, we use a streamlined approach to earthquake retrofitting for multifamily and commercial properties. From initial seismic assessment through design, permitting, construction, and final inspection, our engineers and contractors coordinate every detail to make your building stronger, safer, and fully code-compliant.
Initial Structural Evaluations
Our engineers conduct a focused seismic inspection, examining the foundation, framing, and load-bearing walls to spot vulnerabilities and confirm whether local soft-story ordinances require a retrofit. This assessment guides a strategic plan that strengthens buildings before the next earthquake.
Custom Seismic Retrofitting Plans
After inspection, we develop a retrofit plan tailored to your building. That could mean foundation bolting, new shear walls, or soft-story reinforcement. By targeting weak spots with the right upgrades, we help your property absorb seismic forces, stay code-compliant, and remain standing when the ground shakes.
Professional Installation Services
Once the retrofit plan is approved, our licensed crews install shear walls, steel braces, and foundation anchors quickly and efficiently. Dedicated project managers oversee each phase to prevent delays, control costs, and verify full seismic-safety compliance while coordinating all Tenant Habitability Plan requirements.
Final Inspections and Quality Assurance
We run a thorough post-retrofit check, verifying every bolt, brace, and shear wall against county code. Once your building passes, we issue the compliance paperwork you need—clear proof it’s earthquake-ready and penalty-free.
Common Questions
Property Owner Questions About Retrofitting
The process begins with a thorough inspection to evaluate structural weaknesses that could lead to earthquake damage. Once vulnerabilities are identified, our team develops a custom retrofitting plan and installs reinforcements such as shear walls, foundation bolts, and bracing systems. Final inspections ensure all upgrades meet local seismic safety regulations throughout Santa Clara County.
Strengthening weak points allows buildings to better withstand seismic forces and reduces the risk of collapse. Reinforcements like steel braces and foundation bolting help distribute earthquake energy more effectively, protecting both occupants and the property itself.
Timelines vary based on building size and complexity of required reinforcements. Most retrofitting projects take a few weeks to complete, but larger structures or extensive upgrades may extend the timeline.
Improving seismic safety makes properties more attractive to buyers and tenants, demonstrating compliance with modern safety standards. Retrofitting can also prevent costly post-earthquake repairs, making it a smart long-term investment.
Pricing depends on factors such as building condition, structural needs, and retrofit scope. Retrofit1 provides transparent estimates so property owners can make informed decisions before starting projects.
THPs address how occupied buildings will maintain safe, habitable conditions during construction. Requirements include noise and dust control measures, temporary relocation provisions when necessary, communication protocols, and construction scheduling that minimizes disruption. We manage all THP requirements from initial planning through final occupancy.
Protect Your Investment and Avoid Compliance Penalties
Mandatory soft-story ordinances throughout Santa Clara County establish firm deadlines for seismic retrofitting. Property owners who miss compliance timelines face substantial fines, increased legal liability, and restrictions on property transactions. Qualified retrofitting contractors maintain full schedules as ordinance awareness increases. Retrofit1 has immediate availability for multifamily projects and can complete compliance assessments within days. Don’t let deadlines put your property at risk.
