Condos carry the biggest earthquake loss assessment story, because owners share the structure and a quake damaging common elements is assessed across every unit. The board's decision to buy or decline the earthquake buy-back directly sets how large that assessment is, and each owner's HO-6 loss assessment limit decides whether they can absorb their share.
Earthquake insurance for homeowners associations
Buys back the earthquake peril the master property policy excludes, so shake damage to the association's buildings is covered instead of landing on unit owners through a special assessment.
Why Coverwatch
- Markets
- Difference-in-conditions and standalone earthquake markets, plus surplus lines carriers that write multi-building associations in California, the Pacific Northwest, and the Wasatch and New Madrid zones a standard property carrier will not endorse.
- Competition
- Carriers compared on the deductible percentage, the buy-back structure, and whether loss assessment is built in, not just the annual premium a board answers to owners for.
- Board record
- We document the earthquake decision the board makes and the disclosure it owes members, so declining or buying the coverage is a defensible, minuted choice rather than a gap discovered after a quake.
For hoa
- What it covers
- Shake damage to the association's buildings and common structures, on a peril the master property policy leaves out.
- What it doesn't
- Each unit owner's interior finishes and belongings, which sit on their own HO-6 policy.

Does an HOA master policy cover earthquake damage?
HOA earthquake insurance is a separate buy-back, because the master property policy excludes earthquake. The association adds it by endorsement or a standalone difference-in-conditions policy at the association level, usually with a percentage deductible. Without it, a quake becomes a special assessment on every unit owner.
Why HOA master policies need separate earthquake coverage
Earthquake is a named exclusion on the master property policy, so the association has to buy the peril back on purpose.
The master policy excludes the peril
Earth movement is excluded on standard property forms, so the master policy that rebuilds after fire or wind pays nothing for shake damage.
A quake becomes a special assessment
When damage to common elements runs past what the association carries, the board levies a special assessment and every unit owner owes a share.
Declining is a board decision on the record
Choosing to carry, under-insure, or decline earthquake is a fiduciary call the board owns.

What's covered, and what isn't
In the policy
Shake damage to common-element structures
HOA earthquake insurance pays to repair or rebuild the association's buildings, foundations, exterior walls, and shared structures such as clubhouses, garages.
The association-level buy-back, endorsement or DIC
The coverage is written either as an earthquake endorsement on the master property policy or as a standalone difference-in-conditions policy that sits…
Loss assessment coverage inside the buy-back
When the association's own earthquake limit is not enough and it special-assesses owners, an assessment endorsement on the association program.
Loss of use for common facilities
Additional living expense and loss of assessment income after a covered quake makes shared amenities or a rentable unit unusable.
Ordinance-or-law code upgrade and retrofit
The added cost of rebuilding a damaged building to current seismic code, including tearing down undamaged sections a code officer condemns and required…
Not in the policy
The unit owner's interior and belongings
Damage from the studs in, plus furniture and personal property, is the owner's responsibility even after a covered quake.
Covered by each owner's HO-6 earthquake option
Landslide, subsidence, and other earth movement
A plain earthquake endorsement responds to shaking, not to landslide, mudflow, sinkhole, or ground settling that follows.
Covered by a difference-in-conditions (DIC) policy
Flood and tsunami inundation
Rising water and a tsunami surge that follows a quake are water perils, not shake damage, so the earthquake buy-back does not respond.
Covered by a flood policy (NFIP or private)
A board decision to decline or under-insure
If owners are special-assessed after a quake and allege the board failed to carry or disclose adequate earthquake coverage.
Covered by Directors & Officers
The master property policy's own perils
Fire, wind, and the other covered causes the master property policy already insures are not what the earthquake buy-back is for.

Claims earthquake pays
The same quake lands differently depending on the buy-back the board bought, the deductible percentage, and the age of the building. These are the seismic claims associations actually face, with the typical cost to repair and settle each.
ScenarioHow the claim happensTypical cost
Common clubhouse or garage collapses
A quake caves in a shared parking structure or damages the clubhouse and pool house beyond repair.
$250K–$5M+
Special assessment cascades to owners
Damage to common elements exceeds the association's earthquake limit, or the board carried no earthquake at all, so it special-assesses every unit.
$25K–$500K+ per unit share
Soft-story condo building racks and shifts
A mid-rise with tuck-under parking on the ground floor racks sideways in a quake and is red-tagged.
$500K–$10M+
Underinsured association exhausts the deductible
A moderate quake damages several buildings, but the 15 percent deductible on a multi-building blanket limit runs into the millions.
$100K–$3M+ deductible
Ranges are typical repair, deductible, and settlement bands for these claim types, not a quote. Actual exposure depends on construction, retrofit status, insured value, seismic zone, and the deductible percentage.

What hoa buyers are required to carry
The limits contracts and statutes set for this line, and what moves your premium and terms.
What buyers require
- California Earthquake Authority (CEA)
- Condo/HOA loss assessment option
- Davis-Stirling (Cal. Civ. Code §5300)
- Annual earthquake disclosure to members
- Lender / Fannie Mae
- May flag the earthquake gap
The CEA offers a common-interest loss assessment coverage on its condo (HO-6) policy that pays a unit owner's share of an association special assessment for earthquake damage to shared property, up to the elected limit. It is the state-backed backstop many California owners rely on.
California common-interest associations must include a summary of the association's earthquake insurance, or a statement that it carries none, in the annual budget report delivered to members each year under Civil Code section 5300. The board's earthquake decision is a disclosed, on-the-record fiduciary act.
Lenders and a Fannie Mae condo questionnaire can flag missing earthquake coverage in a high-seismic project, and reserve studies increasingly model seismic risk, so an uninsured gap can surface at a unit sale or refinance.
What sets your cost and terms
- Total insured value and number of buildings
- Replacement cost of all buildings and common elements is the primary rating base, and because the deductible is a percentage of it.
- Construction, retrofit status, and building type
- Un-reinforced masonry and soft-story buildings rate at the top of the scale, while a completed seismic retrofit or a wood-frame low-rise rates lower.
- Seismic zone and proximity to a fault
- Distance to a mapped fault and the zone's modeled severity drive the rate more than almost anything else.
How this changes by hoa segment
The policy is the same product; the exposure, the limit, and the exclusions to watch shift by segment.
Whether the association even needs earthquake on the buildings depends on the governing documents. Where owners hold fee-simple title to their structures the earthquake buy-back may cover only common areas, so each owner has to carry the shake peril on their own structure, and the assessment exposure is narrower than a condo's.
A single-family HOA usually insures only shared amenities, entry structures, and common land, so the earthquake buy-back is smaller and the assessment risk is concentrated in the clubhouse, walls, and pool house rather than the homes. Owners carry earthquake on their detached houses themselves.
In a co-op the corporation owns the whole building, so the earthquake buy-back reaches far more of the structure and interiors than a condo master does. That concentrates the seismic replacement-cost exposure on the association program and makes the deductible percentage a decision that touches every shareholder.
Endorsements that close the gaps
The base form is the start. These add-ons are where the policy gets built to fit hoa.
Difference-in-conditions (DIC) policy
A standalone form that sits alongside the master property policy and adds earthquake, and often related earth-movement perils, that a plain endorsement omits.
Ordinance-or-law and building-code upgrade
Pays the added cost of rebuilding a damaged building to current seismic code and required retrofit standards.
Loss assessment buy-up
Raises the earthquake loss assessment limit, on the association program or each owner's HO-6.
By the numbers
The percentage deductibles, state-backed options, and disclosure duties that surface when an association gets an earthquake buy-back quoted or a board decides whether to carry it.
- Earthquake deductible basis
- 10%–25% of insured value
- California take-up rate
- Roughly 1 in 10 policyholders
- CEA loss assessment option
- Common-interest coverage on the condo policy
- HO-6 loss assessment default
- Often $1,000 standard; buy up to $50,000+
- Davis-Stirling disclosure duty
- Annual earthquake insurance summary
Residential and association earthquake coverage uses a percentage deductible rather than a flat dollar amount, typically 10 to 25 percent of the insured value, so a multi-building association's retained share of a quake loss runs into the millions.
Only about ten percent of California residents carry earthquake insurance despite the state's exposure, a low take-up rate that is the same reason many associations carry no earthquake buy-back until a lender or a member question forces the decision.
The California Earthquake Authority offers a loss assessment coverage on its condominium (HO-6) policy that pays a unit owner's share of an association special assessment for earthquake damage to shared property, up to the elected limit.
A standard unit-owner HO-6 includes only a small loss assessment default, frequently $1,000, and many policies sublimit or exclude earthquake assessments, so the limit has to be raised on purpose to fund a post-quake special assessment.
California Civil Code section 5300 requires a common-interest association to include a summary of its earthquake insurance, or a statement that it carries none, in the annual budget report delivered to members each year.
Common questions
about earthquake for hoa insurance
No. Earthquake is a named exclusion on standard property forms, so the master property policy that rebuilds after fire, wind, or water pays nothing for shake damage. The association has to buy the peril back on purpose, either as an earthquake endorsement on the master policy or as a standalone difference-in-conditions policy written alongside it. Both carry a percentage deductible rather than a flat dollar amount, which for a multi-building association can run into the millions. If the board carries no earthquake coverage, a quake that damages common structures becomes a special assessment on every unit owner, so the decision to buy or decline is one the board has to make deliberately and, in California, disclose to members every year.
Loss assessment coverage sits on a unit owner's HO-6 and pays the owner's share when the association levies a special assessment after a covered loss. It is the bridge between the association's earthquake decision and the household. After a quake, if damage to common elements runs past what the association carries, or if the association carried no earthquake at all, the board special-assesses owners and the HO-6 loss assessment limit funds each owner's share. The catch is that standard limits are small, frequently between $1,000 and $50,000, and many HO-6 policies sublimit or exclude earthquake assessments entirely. Owners in a seismic zone should confirm their policy includes earthquake in the loss assessment grant and raise the limit to match the association's real exposure.
Earthquake carriers use a percentage deductible, commonly 10 to 25 percent of the insured value, because a single quake can damage many buildings at once and they need the association to retain a meaningful share of a catastrophe loss. For a multi-building association that percentage translates into a very large number. A community insured for twenty million dollars with a 15 percent deductible retains three million before the carrier pays anything, which is often more than the association holds in reserves. This is why a moderate quake can leave the carrier paying little of the repair and the board special-assessing owners for most of it, and why the deductible percentage is the single most important term a board negotiates on the buy-back.
Most states do not require an association to carry earthquake, so buying or declining it is a fiduciary decision the board makes. Disclosure is a different matter. In California, the Davis-Stirling Act requires a common-interest association to include a summary of its earthquake insurance, or a statement that it carries none, in the annual budget report delivered to members under Civil Code section 5300. That makes the board's earthquake decision an on-the-record act. A board that declines coverage should document why in its minutes, because owners who are later special-assessed after a quake can allege the board failed to insure or disclose adequately, which is a directors and officers exposure rather than a property claim.
The association levies a special assessment and each unit owner pays a share, usually proportional to their ownership interest. Where the association carried an earthquake buy-back, the assessment covers only the percentage deductible and any loss above the association's limit, so it is smaller. Where the association carried no earthquake at all, the entire cost of repairing common elements is assessed to owners. Each owner then looks to the loss assessment coverage on their HO-6 to fund their share, but that only helps if the limit is high enough and the policy actually includes earthquake assessments, which many do not. An owner without adequate loss assessment coverage pays the balance out of pocket, which is how a single quake can financially threaten households across a community.
A difference-in-conditions, or DIC, policy is a standalone form that sits alongside the master property policy and fills the perils it excludes, most importantly earthquake and often related earth movement such as landslide and subsidence. An association can add earthquake by a simple endorsement on the master policy, but a DIC is broader: it responds to more earth-movement causes and can carry its own limit and deductible structure independent of the master policy. Multi-building associations in high-severity zones such as coastal California, the Cascadia region, and the Wasatch fault usually go the DIC route because the standard property carrier will not endorse the risk, and the DIC market has the appetite and the broader form to cover it properly.
