What your homeowners policy does not cover
Standard California homeowners policies (HO-3, HO-5, dwelling fire) explicitly exclude earth movement — including earthquake shaking, aftershocks, soil settlement, and related landslide triggered by a seismic event. If an earthquake cracks your foundation, destroys your kitchen, or renders the home uninhabitable, your homeowners carrier will deny the claim.
Earthquake coverage must be purchased separately — as a standalone policy, a CEA policy through your homeowners carrier, or through the private market accessed by an independent broker.
Coverage A — earthquake dwelling
Dwelling coverage pays for covered earthquake damage to the structure of the home — walls, foundation, roof, attached structures — subject to the deductible and selected limit. Most homeowners select a dwelling limit equal to their homeowners Coverage A value, though the appropriate limit depends on actual rebuilding cost.
Key points to understand before binding:
- Deductible is applied to the dwelling limit, not the claim — a 15% deductible on a $700k home means $105k before coverage responds.
- Coverage responds to direct earthquake shaking damage, but exclusions vary by form — read the earthquake exclusion language carefully.
- Aftershocks within a defined period are typically treated as part of the same occurrence under most policy forms.
Coverage C — contents and belongings
Personal property coverage pays for earthquake damage to furniture, electronics, appliances, clothing, and other contents. It is selected separately from dwelling coverage and may have its own deductible structure depending on the policy form.
- Some forms apply the same percentage deductible as dwelling coverage to personal property claims.
- Other forms use a flat deductible (e.g., $1,500–$5,000) for personal property regardless of the dwelling deductible selected.
- Higher-value items — art, jewelry, wine collections — may need separate scheduled coverage or riders.
Additional living expenses after an earthquake
Loss of use (ALE) coverage pays for reasonable additional living expenses when earthquake damage makes the home uninhabitable — hotel stays, rental costs, meals, and related costs during repairs. This coverage is often underappreciated until it's needed.
After a significant regional earthquake, contractor availability can be severely limited, extending the period of displacement. A generous ALE limit — some policies offer 20–30% of dwelling limit — can matter significantly in a major event scenario. Many policies have no deductible on the ALE portion.
Coverage for code-required repairs beyond the damage
California's Title 24 building code and local amendments frequently require that repaired structures meet current seismic standards — even if the original damage was limited. This can add substantially to the cost of repairs that would otherwise be straightforward.
Building code upgrade (BCU) coverage pays the additional cost of bringing earthquake-damaged repairs up to current code requirements. Carriers offer BCU as a sublimit — commonly $10,000–$100,000 or more — added to the base dwelling limit.
- Older homes are most exposed to BCU costs — more repairs are likely to trigger code requirements.
- BCU is separate from the dwelling limit and typically does not have an additional deductible on most forms.
- Selecting too small a BCU sublimit can create a significant uninsured gap in renovation-heavy repairs.
Coverage for HOA assessments after earthquake damage
Condominium owners face an additional exposure: if the HOA's master earthquake policy is exhausted or the HOA is uninsured for earthquake, the association can levy a special assessment against individual owners to fund repairs.
Loss assessment coverage on the unit-owner's earthquake policy can cover the owner's share of an HOA assessment from a covered earthquake event, up to the policy limit. This coverage is often inexpensive relative to the exposure it addresses, especially in older condo buildings.
