A major earthquake can do more than damage a building. For owners considering an Oregon seismic retrofit for commercial buildings, the primary concerns are business disruption, tenant displacement, costly repairs, and long-term property value.
Oregon’s earthquake risk is heavily influenced by the Cascadia Subduction Zone, which can produce large, long-duration earthquakes affecting Portland and other inland areas across the Pacific Northwest.
If you own or manage a commercial or industrial building in Oregon, understanding your building’s risk is an important first step.
Does Your Oregon Commercial Building Need a Seismic Retrofit?
Many commercial and industrial properties in Oregon were built before major seismic life-safety improvements became standard in 1997. While seismic codes evolved over several decades, many lenders, insurers, and engineers view buildings constructed before 1997 as potential retrofit candidates that should be evaluated for seismic risk.
In this region, earthquake risk is less about how often events occur and more about how they behave. A Cascadia event can produce prolonged shaking across a wide geographic area, increasing the potential for structural damage, tenant disruption, and operational downtime.
Even buildings that met code at the time of construction may not perform as expected during a major seismic event.
What This Means for Building Owners in Oregon
Oregon does not have a statewide mandate requiring seismic retrofits for all existing commercial buildings. However, that does not mean retrofitting is optional in every situation.
In many cases, seismic upgrades are trigger-based. Requirements can come into play when a building undergoes major renovations, structural alterations, or a change in occupancy. Local jurisdictions— especially higher-risk areas like Portland—may require upgrades as part of the permitting process.
At the same time, some municipalities encourage voluntary retrofitting through incentive programs rather than broad mandates. Because of this, it often makes sense to evaluate your building early, particularly before major projects, refinancing, or operational changes are underway.
Which Commercial Buildings Are Most at Risk?
Some building types are more vulnerable to earthquake damage, especially those built before updated seismic design standards.
Unreinforced masonry (URM) buildings are one of the most common concerns. These brick structures lack internal steel reinforcement, making them more susceptible to cracking or structural failure during seismic events.
Concrete tilt-up buildings are also common throughout industrial and warehouse properties. Older tilt-ups may not have adequate roof-to-wall connections, increasing the risk of wall separation during strong shaking.
Soft-story commercial buildings—those with open ground floors used for parking, retail, or loading— can also be vulnerable because the first floor may become a structural weak point during an earthquake.
Retrofits for these buildings typically focus on strengthening critical structural connections and improving how seismic forces move through the structure.
Because every building is different, retrofit strategies are developed in coordination with engineers and tailored to the specific property and its use.
If your building falls into one of these categories, a seismic evaluation can help clarify your level of risk and available options.

Life Safety vs. Functional Recovery
One of the most important distinctions for commercial building owners is the difference between life safety and what happens after an earthquake.
Life safety means the building is less likely to collapse, and occupants can exit safely. Most building codes are designed around this baseline level of performance. But for commercial and industrial properties, that is only part of the picture.
Functional recovery is about how quickly a building can be used after an earthquake. A building may remain standing but still need extensive repairs, causing tenant disruptions and operational delays.
A seismic retrofit reduces the risk of collapse and increases the likelihood your building remains usable—supporting tenants, operations, and long-term revenue.
Why Lenders and Insurers Pay Attention
Seismic risk also affects financing, insurance, and long-term property value.
Lenders and insurers often evaluate exposure using Scenario Expected Loss (SEL) and Scenario Upper Loss (SUL), which estimate how a building is likely to perform under different earthquake scenarios.
These projections can influence loan terms, insurance availability, and underwriting decisions. Retrofitting can reduce projected losses and strengthen your position with lenders, insurers, and investors.
When Should You Evaluate Your Building?
You don’t need to wait for a mandate or visible damage to start thinking about seismic risk.
It often makes sense to evaluate your building if:
- It was constructed before 1997 or has not been evaluated for current seismic performance by a structural engineer
- You are refinancing or planning a sale
- You are planning renovations or changes in occupancy
- You want a clearer understanding of long-term risk
Starting early gives you more flexibility. It allows you to plan improvements on your timeline, manage costs more effectively, and avoid reactive decisions later.
Start with a Clear Understanding
Seismic retrofitting begins with understanding your building—not by jumping straight into construction.
At Saunders Seismic, we’ve specialized in commercial and industrial seismic retrofitting since 1984. Our team brings decades of hands-on experience working with complex, occupied buildings, where planning must account for both structural performance and ongoing operations.
We work closely with owners, engineers, and stakeholders to review building conditions, provide clear and realistic budgeting guidance, and develop retrofit strategies that align with how your building is used.
We serve commercial and industrial property owners across the West Coast, including California, Oregon, Washington, Nevada, and Utah.
If you’re unsure of your building’s seismic readiness, contact us to schedule a free consultation. Let’s discuss your property and take the next steps toward greater safety and peace of mind.
