AB 1 California Assembly · 2025-2026 Regular Session

Residential property insurance: wildfire risk.

Summary
Existing law generally regulates classes of insurance, including property and fire insurance. Existing law creates the Department of Insurance, headed by the Insurance Commissioner, and prescribes the department's powers and duties. Existing department regulations prohibit an insurer from using a rating plan that does not take into account and reflect specified wildfire risk mitigation, including property-level building hardening measures. This bill would require the department, on or before January 1, 2030, and every 5 years thereafter, to consider whether or not to update its regulations to include additional building hardening measures for property-level mitigation efforts and communitywide wildfire mitigation programs. As part of this consideration, the bill would require the department to consult with specified agencies to identify additional building hardening measures to consider, as well as to develop and implement a public participation process during the evaluation.

MINOR
AB 1 passed through the California Legislature without any substantive changes to its operative text. The diff reflects only procedural and formatting updates: removal of line numbers, addition of passage dates (Assembly June 2, 2025; Senate September 11, 2025), addition of a Governor's approval block, and standard enrolled-bill formatting. The bill itself - requiring the Department of Insurance to periodically review its Safer from Wildfires regulations starting January 1, 2030 - is unchanged from introduction.
TECHNICAL

Header changed from introduced-bill format (with coauthor list, vote/appropriation info, and corrections notes) to enrolled-bill format with passage dates and Governor's approval line.

Line numbers removed throughout the operative text; page layout reformatted to standard enrolled bill pagination.
