Estimate annual CEA earthquake insurance premiums for a Peninsula home — using year built, construction type, and fault proximity.
Standard homeowner's insurance policies explicitly exclude earthquake damage. The San Francisco Peninsula sits between the San Andreas Fault (offshore to the west) and the Hayward Fault (to the east) — both capable of major earthquakes. The USGS estimates a 72% probability of a 6.7+ magnitude earthquake in the greater Bay Area within the next 30 years. Without earthquake insurance, a major earthquake could result in complete loss of the home's structural value with no insurance recovery. Lenders don't require it, but the risk on the Peninsula is more acute than almost anywhere else in California. The decision should be made with full awareness of the risk, not by default.
The CEA is the largest residential earthquake insurance provider in the world. A standard CEA policy covers: the dwelling structure at your chosen limit; loss of use (additional living expenses while uninhabitable); and personal property at a fixed sublimit. CEA policies do not cover: separate garage structures (endorsement needed); swimming pools; fences; masonry chimneys; or landscaping. The standard deductible is 15-25% of dwelling coverage — on a $1.5M dwelling policy, you absorb $225,000 to $375,000 before insurance pays.
The five most important factors: (1) Year of construction — pre-1940 homes, especially unreinforced masonry, carry the highest premiums; post-1980 wood frame homes have lower rates; (2) Foundation type — cripple wall and soft-story foundations are higher risk than bolted slab; (3) Proximity to active fault lines — parcels within 3 miles of the San Andreas or Hayward faults have higher rates; (4) Soil type — liquefaction-prone fill soils (Bay-adjacent) increase risk; (5) Dwelling replacement value. Wood-frame homes built after 1980 on firm soil can have surprisingly affordable premiums; pre-1940 unreinforced masonry homes can be difficult to insure at any price.
CEA standard deductibles are expressed as a percentage of dwelling coverage: typically 10%, 15%, 20%, or 25%. On a $2M dwelling coverage policy, a 15% deductible means you pay the first $300,000 of any claim. Lower deductibles mean higher premiums. Buyers with significant liquid assets post-closing may rationally choose a 20-25% deductible in exchange for lower annual cost. Buyers with limited liquid assets should consider the 10% deductible despite the premium increase — the deductible amount on a serious earthquake claim is the difference between financial survival and financial devastation.
