Earthquake Retrofitting in Oakland
Soft-Story You Can Rely On When It Matters Most
Oakland Faces One of California’s Highest Earthquake Risks
Oakland sits along the Hayward Fault, one of the most active fault lines in the country. With many older buildings across the East Bay, earthquake retrofitting in Oakland isn’t just a smart investment—it’s often required for multifamily properties.
Seismologists warn that a major Bay Area earthquake is a matter of when, not if. The USGS projects a significant chance of a magnitude 6.7 or greater quake in the coming decades, with the potential for severe damage and displacement.
Soft-story buildings, especially those with open ground floors, are particularly vulnerable. That’s why Oakland has some of the strictest seismic retrofit requirements in California—to protect tenants, preserve property value, and strengthen building safety.
Is Your Building Required to Retrofit?
Oakland’s Mandatory Soft-Story Ordinance (Ordinance 13516) requires seismic upgrades for buildings most at risk of collapse during a major earthquake.
Your building may be required to complete retrofitting in Oakland if it has:
- Wood-frame construction with a soft story (such as tuck-under parking or an open garage level)
- Five or more residential units
- Construction permitted before January 1, 1991
Many older apartment buildings in neighborhoods like Temescal, Rockridge, Adams Point, and West Oakland fall into these categories.

Building Tiers and Deadlines
Oakland assigned buildings into compliance tiers based on occupancy and risk level:
- Tier 1 (20+ units): Deadline passed February 2023
- Tier 2 (5–19 units or mixed-use): Deadline passed February 2024
- Tier 3 (residential soft-story): Deadline February 21, 2025
If Tier 1 or Tier 2 deadlines have passed, the building may already be out of compliance. Tier 3 owners now have limited time remaining to complete evaluation, permitting, and construction.
Single-family homes and duplexes are not subject to the mandatory ordinance, but many Oakland homeowners still pursue voluntary earthquake retrofitting near me solutions to improve safety and qualify for incentives.
Financial Help Is Available for Oakland Property Owners
Retrofitting is often more affordable than owners expect, especially with local and statewide programs designed to reduce cost barriers.
Oakland’s $250 Flat Fee Permit Program
Oakland offers a reduced permit cost for qualifying homeowners retrofitting single-family homes or duplexes. Eligible projects pay a flat $250 permit fee rather than standard fees that can reach thousands.
Work must follow current seismic standards using Plan Set A (prescriptive retrofit) or an engineered retrofit design.
State Grant Programs
Earthquake Brace + Bolt (EBB): Eligible homeowners may receive up to $3,000 toward code-compliant foundation bolting and bracing. Income limits apply.
Earthquake Soft-Story (ESS) Grant: Some qualifying properties may receive grants up to $13,000 for retrofits involving living space above garages.
Our team helps Oakland property owners understand which programs apply and how to move forward quickly.

Soft-Story Retrofitting
Soft-story buildings with open ground floors lack lateral support and are among the most collapse-prone structures in earthquakes. We install steel moment frames, engineered shear walls, and structural reinforcements designed to meet Oakland retrofit ordinance standards while preserving parking or commercial use.
Foundation Strengthening
A secure foundation is essential for seismic performance. We reinforce weak points, repair cracks, upgrade footings, and ensure proper anchorage between the foundation and framing above.
Earthquake Brace + Bolt
Many older Oakland homes were built without sufficient foundation connections. We install steel anchor bolts and plywood bracing to prevent sliding during earthquake shaking. This work often qualifies for Oakland’s permit incentives and Plan Set A standards.
Tenant Habitability Planning
For occupied multifamily buildings, we create Tenant Habitability Plans that minimize disruption and keep residents safely housed while meeting Oakland’s compliance requirements.
What to Expect: Our 4-Step Process
Step 1: Property Evaluation
We begin with a detailed structural assessment to identify vulnerabilities and determine exactly what your Oakland building needs. This also confirms whether Plan Set A applies or an engineered solution is required.
Step 2: Customized Retrofit Design
Our licensed structural engineers design a retrofit plan tailored to your building’s conditions and the City of Oakland’s ordinance requirements. We handle permitting and coordination with local departments.
Step 3: Professional Installation
Our experienced retrofit crews install steel frames, shear systems, foundation anchors, and bracing. Most earthquake retrofitting projects in Oakland take 2 to 6 weeks, and tenants can often remain in place during construction.
Step 4: Final Inspection and Compliance
We coordinate final city inspections and submit all required compliance documentation so your property is fully protected and legally compliant.

Common Questions
Answers About Costs, Permits, Timelines, and Tenants
Single-family homes typically range from $5,000 to $15,000 for standard bolting and bracing. Soft-story multifamily buildings often range from $50,000 to $500,000, depending on size, access, and engineering needs.
We provide detailed estimates after your evaluation, and grants can significantly reduce out-of-pocket expenses.
Most retrofitting in Oakland takes 2 to 6 weeks, though larger buildings may take longer due to permitting and scope.
Usually not. Most work occurs at ground level or exterior structural areas. In rare cases involving extensive foundation work, temporary relocation may be needed for safety.
Plan Set A is a pre-approved retrofit plan for simple residential structures. Qualification depends on:
- 1–2 family buildings
- Two stories or less
- Wood-frame construction
- Continuous perimeter foundation
Buildings outside these criteria require engineered plans.
Yes. Oakland’s $250 permit program and state grants like EBB and ESS can help offset retrofit costs.
Yes. Retrofitted buildings are safer, more attractive to buyers and tenants, and often retain stronger value as ordinance enforcement increases.
