Earthquake coverage is not in your standard HO-6
Standard HO-6 and master property policies exclude earthquake damage. In California, Washington, Utah, and other seismic zones, recovery may depend on separate earthquake insurance for the association, the unit, or both. Without it, repair costs after a major event can flow through special assessments even when fire following earthquake is partially covered elsewhere.
Buyers moving from non-seismic markets often assume master HOA insurance handles all catastrophe risk. Earthquake is its own line item in budgets, minutes, and your personal coverage plan.

Master policy vs unit earthquake coverage
| Layer | Typical scope | Buyer question |
|---|---|---|
| Association master EQ | Common structure and shared elements in some buildings | Does the HOA carry a master earthquake policy? |
| Unit owner EQ | Interior finishes and belongings per policy | Do you need CEA or private unit coverage? |
| Deductible type | Often percentage of building value | What assessment risk hits owners after a claim? |
| Loss assessment | Owner share of master shortfall | Are HO-6 limits high enough? |
Older California associations may have let master earthquake coverage lapse when premiums rose. Minutes and budget insurance lines reveal whether the building carries EQ or expects owners to self-insure through assessments.
- Request master earthquake declarations, not only fire and liability pages
- Confirm whether parking structures and podiums share the same EQ policy
- Quote unit earthquake coverage even when master exists
- Compare deductible percentage to loss assessment limits on HO-6
Deductibles and assessment risk after a quake
Earthquake policies often use percentage deductibles on building insured value. A 15% deductible on a $50 million complex creates a multi-million dollar owner funding gap before coverage pays. Associations assess owners to fund the deductible layer. Your HO-6 loss assessment rider may help only within its limits and policy terms.
Example: Illustrative deductible math
Insured building value is $40 million with a 10% earthquake deductible ($4 million). One hundred units share equally on a simple per-unit basis: $40,000 before insurer payment on a major claim. Loss assessment coverage of $25,000 leaves a gap unless the association structures payments over time.

California and West Coast buyer steps
- Read California budget EQ premium line or confirm coverage is absent.
- Quote CEA or private unit policy for interiors and personal property.
- Check minutes for lapsed coverage votes or failed premium renewals.
- Review soft-story or seismic retrofit plans that may precede assessments.
- Compare buildings in the same search with and without master EQ coverage.
Seismic retrofit mandates in some cities can trigger long construction timelines and temporary assessments. Cross-check high-risk condo markets and local city pages under states.
Fire following earthquake
Some property policies cover fire damage after a quake while excluding shaking damage. Do not assume that clause replaces a full earthquake strategy for structural and interior losses.
Earthquake insurance checklist
- Master earthquake policy status confirmed in writing
- Unit earthquake quote stored with HO-6 paperwork
- Deductible percentage translated to per-unit assessment risk
- Loss assessment limits reviewed against master EQ deductible
- Retrofit or engineering projects noted in minutes and reserve study
- Monthly budget includes EQ premium trend, not only current year
Frequently asked questions
- Is earthquake insurance required for condos?
- Lenders may require it in high seismic zones. Even when optional, many buyers carry it because standard HO-6 excludes shaking damage.
- Does the HOA earthquake policy cover my unit interior?
- Depends on policy structure. Many master EQ policies focus on the building while unit owners need separate coverage for interiors and belongings.
- What is a typical earthquake deductible?
- Often 10 to 25 percent of insured building value on master policies, which can drive large owner assessments before coverage responds.
- Can I buy earthquake insurance after I move in?
- Usually yes through CEA or private carriers, but waiting risks a gap if a event occurs before binding. Quote during diligence.
