5 Earthquake Questions Every California HOA Board Should Be Asking Right Now
You don't need to be a seismologist to protect your community. You just need to ask the right questions.
Serving on an HOA board means juggling a dozen priorities — maintenance schedules, reserve studies, vendor contracts, homeowner complaints. Earthquake risk tends to sit at the bottom of the list, somewhere between "important" and "we'll deal with it later."
The problem is that earthquakes don't wait for a convenient time. And when they hit, the financial consequences for a condominium community can be staggering — not because of the shaking itself, but because of what the board didn't know about its own exposure.
Here are five questions every California HOA board should be asking right now — and why the answers matter more than most directors realize.
1. "How close are we to an active fault — and what does that actually mean for our buildings?"
California has more than 500 active faults, and no community in the state is completely free from seismic risk. But proximity matters enormously. A community five miles from the San Andreas Fault has a very different risk profile than one 30 miles away — and the difference shows up in both the probability of strong shaking and the expected severity of damage.
What matters isn't just distance, though. It's also:
- Soil type. Buildings on fill, bay mud, or alluvial soil can experience significantly amplified shaking compared to those on bedrock. Liquefaction — where saturated soil temporarily loses its strength — can cause foundations to shift, tilt, or sink.
- Building age and construction type. Pre-1980 buildings were constructed under older seismic codes that didn't account for what engineers now understand about earthquake forces. Wood-frame, tilt-up concrete, and soft-story structures each have distinct vulnerabilities.
- Building configuration. Ground-floor parking garages, large window openings, and irregular floor plans create structural weak points that can concentrate damage.
Most boards know their community's address. Few know how these factors combine to create a specific, quantifiable risk profile for each building on the property.
What to do: Ask your risk advisor to explain your community's seismic exposure in specific terms — not just "we're in California." If they can't provide building-level detail, that's a gap worth filling.
2. "What would our insurance actually pay after a magnitude 6.5 earthquake?"
This is the question that surprises most boards. The answer is often: less than you think.
Commercial earthquake policies for HOAs use per-building deductibles, typically 10% to 25% of each building's insured value. In a moderate earthquake — the kind most likely to occur — damage to individual buildings may fall entirely within those deductibles. The insurance policy technically responds, but pays nothing because no single building's damage exceeds its deductible threshold.
The result: millions of dollars in aggregate damage across the community, and the full repair bill lands on the association.
Consider this: in the 1994 Northridge earthquake (magnitude 6.7), total insured losses exceeded $20 billion. But a significant portion of HOA damage fell within deductibles — leaving associations to fund repairs through emergency special assessments that hit some homeowners with bills exceeding $50,000.
What to do: Don't just review your policy limits. Ask your broker to model what your policy would pay under two or three realistic earthquake scenarios. If they can't provide that analysis, an independent risk assessment can.
3. "Could we survive a special assessment in the six figures — per unit?"
This is the question boards don't want to ask. But it's the one that determines whether your community recovers from an earthquake or spirals into financial crisis.
Under California's Davis-Stirling Act, HOA boards have the authority — and potentially the obligation — to levy special assessments to cover uninsured losses. There's a practical limit, though: if homeowners can't pay, the assessment becomes a collections problem that drags on for years.
Boards should consider:
- What's the deductible gap? The difference between likely earthquake damage and what insurance will actually pay. For many communities, this is measured in tens of millions of dollars.
- What are the reserve fund levels? Reserves can be a first line of defense, but most are funded for scheduled maintenance — not catastrophic events. Tapping reserves for earthquake repair creates a cascade of deferred maintenance.
- What's the demographic reality? Communities with fixed-income homeowners (especially 55+ communities) face a harder path to recovery. Large assessments can force sales, depress property values, and fracture the community.
What to do: Run the numbers now, not after an earthquake. Understanding the potential assessment exposure helps boards make informed decisions about coverage levels, reserve allocation, and whether additional financial planning is needed.
4. "Are we meeting our fiduciary duty on earthquake preparedness?"
This is the one that should keep board members up at night.
Under California law, HOA directors have a fiduciary duty to act in the best interest of the association. Courts have consistently held that this includes making informed decisions about insurance coverage and risk management.
The Davis-Stirling Act doesn't explicitly require HOAs to carry earthquake insurance (unless required by the governing documents). But the legal analysis published on leading HOA law resources is clear: boards in high-risk areas that choose not to carry earthquake coverage — or that carry inadequate coverage without analyzing the alternatives — may face personal liability if the community suffers uninsured losses.
Key considerations:
- Informed decision-making. A board that votes against earthquake insurance after reviewing a detailed risk analysis is in a much stronger legal position than one that simply never discussed it.
- Documentation matters. Board minutes should reflect that earthquake risk was discussed, options were evaluated, and a decision was made based on available data.
- The business judgment rule. Directors are generally protected from liability for good-faith business decisions. But that protection requires the decision to be informed. A board that has never seen building-level loss estimates hasn't met that standard.
What to do: Put earthquake risk on the agenda. Even if the board ultimately decides the current coverage is adequate, documenting that the discussion happened — and that it was based on actual data — protects individual directors.
5. "Do we have building-level data, or are we relying on assumptions?"
Most HOA boards make earthquake-related decisions based on very little actual data. The broker provides a policy with limits and deductibles. The reserve study mentions earthquake as a risk factor. Maybe someone mentions "we're near a fault" at a board meeting.
None of that is the same as knowing your actual exposure.
Building-level earthquake loss estimates model what would happen to each specific structure in your community under various earthquake scenarios. They account for construction type, building age, soil conditions, fault proximity, and the specific seismic hazard at your location. The output is a number — a dollar amount representing the expected damage to each building at different shaking intensities.
That number is what allows boards to:
- See whether insurance deductibles are appropriate for the actual risk
- Identify which buildings are most vulnerable
- Make data-driven decisions about coverage levels
- Communicate clearly with homeowners about the community's exposure
- Satisfy fiduciary duty requirements with documented analysis
Without building-level data, boards are essentially guessing. With it, they're governing.
What to do: Get a per-building earthquake risk assessment. EQE Risk's Rapid Risk tool offers a free initial screening that takes minutes. For a comprehensive analysis, independent assessment firms can model your community's specific exposure and provide the numbers your board needs to make informed decisions.
Don't Wait for the Earthquake to Find Out
California's seismic risk isn't theoretical. It's geological fact. The question for HOA boards isn't whether an earthquake will affect your community — it's whether your board will be prepared when it does.
The five questions above aren't complicated. But asking them — and demanding real answers — is the difference between a board that governs proactively and one that finds out the hard way what their coverage was really worth.
Start with the data. The rest follows from there.
