Earthquake Retrofitting in Berkeley, CA
Turn Your Soft Story into a Stronghold
Berkeley sits in one of the Bay Area’s highest-risk seismic corridors, where older wood-frame homes, hillside properties, and buildings with open ground floors face different retrofit challenges. We help homeowners, landlords, and property managers strengthen vulnerable structures with brace and bolt work, soft-story retrofits, foundation repairs, and permit-ready seismic upgrades based on the property’s actual risk profile.
Built for Berkeley's Fault, Housing Stock & Code Requirements
The USGS puts the odds of a magnitude 6.7+ quake on the Hayward Fault within 30 years at roughly 1-in-3, and a repeat of the 1868 rupture would hit this side of the bay first and hardest. Much of the housing in its path is older wood-frame construction, including the types of soft, weak, or open-front buildings addressed by Berkeley Municipal Code Chapter 19.39.
For owners of SWOF buildings with five or more units, the ordinance requires tenant notification, retrofit compliance, and a clear path through city review. For single-family and hillside properties, the priority is different but just as urgent: anchoring the home, strengthening weak cripple walls, and reducing the chance that the structure shifts off its foundation during a major quake.

Built to Handle Berkeley Retrofit Challenges
A seismic retrofit needs to match the building, satisfy code, and hold up when lateral forces hit. Retrofit1 brings 700+ completed retrofit projects and practical experience with Berkeley’s older homes, hillside lots, open parking areas, and SWOF buildings.
What makes our approach stronger:
- Plans built around the actual structure, not a one-size-fits-all brace and bolt package
- Experience with Berkeley SWOF buildings subject to Chapter 19.39 requirements
- Engineering and construction coordinated early so the scope is code-conscious and buildable
- Soft-story solutions for open parking, storefronts, and weak ground-floor layouts
- Tenant habitability planning for occupied multifamily buildings
- One accountable team from inspection and planning through completed work

Soft-Story Retrofitting
Buildings with open ground floors are highly vulnerable during earthquakes. Soft-Story Retrofitting strengthens the base with steel frames and shear walls to improve stability and reduce collapse risk.
Earthquake Brace & Bolting
Older structures are often not securely anchored to their foundations. Earthquake Brace & Bolting reinforces the connection with anchor bolts and bracing to prevent shifting.
Foundation Repair Services
Cracking or settlement weakens structural support. Foundation Repair Services stabilize and restore the base to ensure retrofit performance.
Tenant Habitability Program (THP)
Occupied buildings must meet tenant protection requirements during seismic work. The Tenant Habitability Program (THP) outlines compliance standards during construction.
Grants, Rebates, and Financing Worth Knowing About
Berkeley property owners may have several ways to offset retrofit costs, depending on the building type, eligibility, and scope of work.
- Earthquake Brace + Bolt (EBB): Up to $3,000 for qualifying raised-foundation wood-frame homes, with added supplemental funding for income-eligible owners.
- Earthquake Soft-Story (ESS): Up to 75% of retrofit costs, capped at $13,000, for eligible Berkeley homes with living space over a garage.
- Berkeley Retrofit Grants Program: Reimburses qualifying multi-unit, mixed-use, hotel, and commercial properties for part of design and construction costs, capped at $150,000.
- Transfer Tax Refund: Available to some owners who complete a seismic retrofit within one year of purchasing the property
- PACE Financing: Long-term financing repaid through the property tax bill when grants do not cover the full project.
From Inspection to Final Sign-Off
Our process is designed to be thorough, efficient, and transparent from start to finish.
Initial Inspection and Assessment
We begin with a detailed inspection of your building’s structural elements. Our licensed contractors examine foundations, framing, and load-bearing components to identify weaknesses and assess seismic risk specific to your property.
Custom Retrofitting Plan
Using the inspection findings, we develop a custom retrofitting plan tailored to your building’s needs. This plan may include foundation bolting, shear walls, steel bracing, or soft-story reinforcement, all designed to meet Berkeley’s seismic safety standards.
Installation and Implementation
Once approved, our retrofitting contractors install all required reinforcements using high-quality materials and proven construction techniques. We work efficiently to reduce disruptions while ensuring every component is properly installed.
Final Inspection
After construction is complete, we conduct a final inspection to confirm that all seismic upgrades meet California and Berkeley code requirements. This step ensures your building is fully compliant and structurally prepared for future seismic activity.
Common Questions
What Owners Want to Know Before Day One
The city publishes a public list of identified SWOF properties, and owners of flagged buildings receive a formal notice. If you are not sure where yours stands, we can check the inventory and pull the record.
In most cases, yes. Soft-story work happens mostly at the ground floor and exterior, and we sequence the job to keep units accessible while meeting the required tenant habitability steps.
Often, yes. Insurers that offer earthquake coverage typically reduce premiums for properly bolted and braced homes, and the California Earthquake Authority offers a hazard-reduction discount for qualifying retrofits. Ask your carrier what proof of work they require before you start.
Non-compliance can trigger administrative citations and complicate tenant notifications and rental registration. Getting into the permit queue is always better than leaving the building flagged and unresolved.
Yes. Hillside properties usually need more attention to hold-downs, cripple walls, and cross-slope bracing. Flatland soft-story buildings typically center on ground-floor shear reinforcement, while properties in Alameda may raise different questions around soil conditions, foundations, and ground movement. The scope is driven by the building, not a template.
Get a Clear Retrofit Plan Before the Next Quake
The safest time to find weak framing, foundation gaps, or soft-story vulnerabilities is before the next major Hayward Fault event. Schedule an inspection with Retrofit1 and get a practical scope built around your property, code requirements, and next steps.
