In September 1996, the state Legislature established the California Earthquake Authority. The CEA is a privately funded, publicly managed organization that provides residential earthquake insurance to Californians. Designed to make quake insurance both available for consumers and financially viable for both insurers and their customers, the CEA is funded by insurance industry capital contributions and commitments, reinsurance and capital market borrowing. As of January 2010, the CEA had more than $9 billion in claims-paying capacity.
State law requires an insurer selling homeowner insurance to offer earthquake coverage. Insurers who choose not to participate in the CEA must offer their own earthquake coverage to their homeowner policyholders. As of January 2010, the CEA had about 800,000 policies in force and 17 participating insurers:
| ACA Insurance | Farmers Insurance Group |
| Allstate Insurance | Foremost |
| Armed Forces Insurance Exchange | Golden Eagle |
| Auto Club of Southern California | Homesite Insurance of California |
| California FAIR Plan | Liberty Mutual |
| California State Automobile Association | Mercury |
| Commerce West | Safeco |
| Encompass Insurance | State Farm |
| USAA |
