Why rates in California look the way they do
California’s auto rates ($1,816/yr NAIC 2023) are middle-of-pack despite urban density and litigation costs, because Prop 103 caps how fast carriers can re-rate. Home insurance is the opposite story: the carrier exodus that started after the 2017 wildfire season has reshaped which carriers will write in which ZIPs.
California is a prior-approval state under Proposition 103 (1988), which means every rate change above 7% requires a public hearing before the Department of Insurance and can be challenged by consumer groups.
Three state-specific dynamics that drive rates here:
- Prop 103 prior-approval system requires public hearings for rate increases above 7%.
- Most major carriers paused new homeowners business in fire-prone ZIPs between 2022-2024; CDI’s Sustainable Insurance Strategy (2024) reopened parts of the market.
- Credit-based insurance scoring is prohibited for auto policies under California law.

What drives California home insurance rates
California is a prior-approval state under Proposition 103 (1988), which means every rate change above 7% requires a public hearing before the Department of Insurance and can be challenged by consumer groups.
Three factors drive most of the dwelling premium: home age + construction class, distance to fire department, and roof age (some carriers exclude roofs over 15 years).
