California Homeowners Insurance

Data Snapshot: California Homeowners Insurance

Across the 1,545 California ZIP codes in the U.S. Treasury FIO data, the average annual home insurance premium is $1,864. That is an average of ZIP codes, in which a ZIP of a few hundred people counts the same as one of tens of thousands. That is 5% above the national average of $1,776 per year reported by the Federal Insurance Office. California ranks 21st most expensive out of 51 states and territories on annual premium, with ZIP-level observations ranging from $825 in 92257 to $11,603 in 90210.

Between 2018 and 2022, average premiums rose by 25.4% in California, placing the state 1st nationally on five-year premium growth. The state-level loss ratio averaged 81.6%, meaning insurers retained a healthy margin after claims, typical of stable markets. Nonrenewal rates, the share of policies insurers decline to extend at expiration, averaged 1.86% across the ZIP codes that report one, a climb of 112.4% over the study period (ranking 6th out of 50 states).

Within California, premium dispersion across ZIP codes is substantial: the most expensive ZIP (90210 in Beverly Hills) charges 1307% more than the least expensive (92257 in Niland), reflecting local differences in catastrophe exposure, construction costs, and claims history. The FIO dataset aggregates voluntary reporting from the 40 largest homeowners insurers covering roughly 80% of the U.S. market, so ZIP-level figures represent market averages rather than individual quotes; actual premiums vary with dwelling value, deductible, coverage limits, and insurer-specific underwriting. This page is a FIO registry extract, not a quote or a recommendation.

How to read these figures: state averages on this page are computed from U.S. Treasury Federal Insurance Office data, which the office collects directly from the largest homeowners insurers and reports at the ZIP-code level. A statewide average blends expensive coastal and wildfire-exposed markets with lower-cost inland areas, so the figure is a useful benchmark but will understate what some residents pay and overstate what others pay. The loss ratio is the share of every premium dollar that insurers returned as claims; sustained ratios near or above one signal a market under pressure, where rate increases, tighter underwriting, or nonrenewals tend to follow. Claim frequency and nonrenewal rates show how often policies result in claims and how often insurers decline to renew, both of which track local catastrophe exposure.
