How to think about home insurance in California: what to buy and why
Updated May 21, 2026 — PolicyChat refreshes this page when new state DOI filings post.
For California homeowners, the question is replacement cost, not market value. Construction costs are up materially since 2020. A home insured for its 2020 dwelling value can be 25-35% underinsured against current rebuild cost.

How to think about this
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.
Replacement cost = current cost to rebuild your specific home with current materials + labor. Some carriers offer guaranteed-replacement-cost coverage (Chubb, PURE, USAA for members); most cap at policy limit, which means underinsurance shows up at exactly the moment you can’t afford it.
California-specific things to know
- 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.
