AB 2517California Assembly·2025-2026 Regular Session
Fire safety: fire hazard severity zones.
Summary
Existing law requires the State Fire Marshal to identify areas in the state that are not state responsibility areas, commonly known as local responsibility areas, as moderate, high, and very high fire hazard severity zones based on consistent statewide criteria and based on the severity of fire hazard that is expected to prevail in those areas. Existing law requires the State Fire Marshal to periodically review and make recommendations relative to very high fire hazard severity zones within local responsibility areas. Under existing law, this review is required to coincide with review of state responsibility area lands every 5 years and, when possible, fall within the timeframes for each county's general plan update. Existing law requires a local agency to designate, by ordinance, moderate, high, and very high fire hazard severity zones in its jurisdiction within 120 days of receiving the recommendations from the State Fire Marshal. Existing law authorizes a local agency to, at its discretion, include areas within its jurisdiction not identified as very high fire hazard severity zones by the State Fire Marshal as very high fire hazard severity zones and areas not identified as moderate and high fire hazard severity zones by the State Fire Marshal as moderate and high fire hazard severity zones. Under existing law, a local agency is required to transmit a copy of this adopted ordinance to the State Board of Forestry and Fire Protection within 30 days of adoption. Existing law provides that changes made by a local agency to the recommendations made by the State Fire Marshal are final. This bill would require the State Fire Marshal to, no fewer than 180 days before finalizing the designation of local responsibility areas as moderate, high, and very high fire hazard severity zones, post specified information relating to those designations on its public internet website, provide at least one workshop on the draft maps for stakeholder participation, host a 30-day public comment period to receive written comments from interested stakeholders, respond to all written comments by local agencies regarding land use and zoning matters that address the accuracy of the data used by the State Fire Marshal for those designations within 30 days of the end of the public comment period, and coordinate with other state agencies to help educate their constituencies, as specified. The bill would also require, on or before January 1, 2030, and every 5 years thereafter, the State Fire Marshal to review the local responsibility area lands designated as moderate, high, and very high fire hazard severity zones and to recommend changes. The bill would end the requirement that this review, when possible, fall within the timeframes for each county's general plan update. The bill would authorize a local agency to, at its discretion, increase the level of fire hazard severity applicable to a parcel in its jurisdiction if a parcel contains 2 or more designations, so that the higher level of fire hazard severity would apply to the entire parcel and include documentation of existing wildfire mitigation efforts or programs implemented locally within the fire hazard severity zones in its jurisdiction. The bill would require the State Fire Marshal to publish within 60 days the local ordinance transmitted to the board, as described above, on its internet website.

MODERATE
The transition from the Amended Assembly version to the final AB2517 text simplifies the public workshop requirements for fire hazard severity zone designations, narrows the scope of written comments that must be responded to by adding a data-accuracy qualifier, and adds language requiring state agencies to educate their own constituencies. A stakeholder definition is also made explicit in the final text.
REQUIREMENT
Section 51178(b)(3) was simplified from a detailed multi-part requirement (regional public workshops held before the comment period, at least one online virtual option, and consideration of oral comments within 30 days) to a single requirement: provide at least one workshop on the draft maps for stakeholder participation, which may be in person or online.
Section 51178(b)(4)(B) now requires the State Fire Marshal to respond to written comments from local agencies regarding land use and zoning matters that address the accuracy of the data used for the preliminary designation, narrowing the response obligation to data-accuracy issues specifically.
Section 51178(b)(5) adds language requiring other state agencies to educate their constituencies (in addition to helping educate the public during workshops) on mitigation activities, fire insurance, and related maps and models.
DEFINITION
A definition of 'stakeholder' is included in Section 51178, specifying that it includes fire departments, fire safe councils, and local agencies.
The amendment adds a dedicated stakeholder workshop requirement, narrows the scope of written comments the State Fire Marshal must respond to (limited to data accuracy issues), adds a definition of 'stakeholder,' allows local agencies to document existing wildfire mitigation efforts in their ordinances, and removes the requirement that the five-year review align with county general plan update timeframes.
REQUIREMENT
New requirement for the State Fire Marshal to provide at least one workshop on draft maps specifically for stakeholder participation, which may be in person or online.
The obligation to respond to written comments from local agencies is narrowed: responses are now only required for comments regarding land use and zoning matters that address the accuracy of the data used by the State Fire Marshal, rather than all land use and zoning comments.
SCOPE
The coordination requirement with other state agencies shifts from helping 'educate the public' to helping 'educate their constituencies,' narrowing the intended audience of the educational efforts during workshops.
DEFINITION
New definition added: 'stakeholder' is defined to include fire departments, fire safe councils, and local agencies for purposes of Section 51178.
ELIGIBILITY
Local agencies are now authorized to include documentation of existing wildfire mitigation efforts or programs implemented locally within their fire hazard severity zones in their ordinances.
TIMELINE
Removed the requirement that the five-year review of local responsibility area lands 'when possible, fall within the timeframes for each county's general plan update.' The review now only needs to coincide with the state responsibility area review every five years.
