California's earthquake fund is stronger than ever. Fewer homes are covered than ever.

The California Earthquake Authority (CEA) was built after the 1994 Northridge quake, when insurers fled the homeowners market rather than keep underwriting a peril they couldn't price.▸ Thirty years later the fund it built to solve that crisis is, by every financial measure, in its strongest position yet. Californians are buying less of it than at any point in the record.

CEA is not a state agency backed by tax dollars — it's a publicly managed, privately funded risk pool.▸ Its capacity to pay claims comes from six layers: cash and investments the fund already holds, revenue bonds sold against future claims, reinsurance bought on the private market, and the legal authority to assess both policyholders and participating insurers after a disaster. As of June 30, 2025, those layers add up to $19.39 billion, per CEA's own annual accounting — its largest claims-paying capacity on record.

The single largest layer is reinsurance — $7.8 billion bought on the private market, more than any other source.▸ Two independent rating agencies confirm the fund can carry it: reprinted in CEA's own report, AM Best models the capacity at a 1-in-365-year return period as of January 1, 2024, and KBRA's August 2025 rating affirmation independently puts the same $19.4 billion at a 1-in-395-year event — both well past anything in California's historical earthquake record. None of that capacity is a taxpayer backstop; it exists because CEA charges enough in premiums and surcharges to fund it, which is also why rates keep climbing — the Insurance Commissioner approved a 6.8% increase in June 2024, effective for policies renewing since January 2025.

A well-capitalized fund only matters to the households actually enrolled in it.▸ Of the 12.9 million residential insurance policies written statewide in 2024 — a figure the California Department of Insurance collects every year through its own earthquake premium and policy-count data call — only 1,609,655 carried earthquake coverage of any kind, CEA or otherwise. That's a 12.48% statewide take-up rate, down from 12.54% the year before. It varies sharply by what's being insured.

Mobile-home owners buy it at nearly twice the statewide rate — the housing type most visibly vulnerable to shaking.▸ Dwelling-fire policies sit at the bottom, 3.38%, and CEA's own report notes why: most of those policies are written by the California FAIR Plan, the state's insurer of last resort for homes insurers won't otherwise cover — a population already priced out of the standard market and, evidently, out of earthquake coverage too. CEA itself remains the largest single earthquake insurer, writing 62% of the state's earthquake policies, but its own book is shrinking: 1,000,249 policies in force at year-end 2024, down 3.9% from a year earlier.

Take-up figures are drawn from CDI's statewide policy-count data call for calendar year 2024 and cover all residential earthquake insurers, not CEA alone; CEA's capacity figures are its own June 30, 2025 accounting, six months out of step with the CDI data, as both agencies report on their own cycles.
