LEGISLATIVE REVIEW COMMITTEE
FROM: ANTHONY, JASON, AND PAUL GONSALVES
SUBJECT: CONSIDER RECOMENDING A POSITION ON AB 2517
(CALDERON) FIRE SAFETY: FIRE HAZARD SEVERITY ZONES
DATE: APRIL 6, 2026
Bill Information:
The official text of AB 2517 can be found here1.
Summary:
AB 2517 improves the state’s process for designating Fire Hazard Severity Zones by increasing transparency, requiring regular updates, and enhancing local government involvement. The bill updates how the State Fire Marshal designates moderate, high, and very high fire hazard zones and requires that these maps be updated on a sciencebased, five-year cycle, replacing the current vague standard of periodic updates.
The measure also establishes a transparent public review process prior to finalizing maps, including opportunities for public input, and improves coordination with local governments. Importantly, it provides cities with a formal opportunity to submit land use and zoning input before maps are finalized.
For cities, the bill offers clear benefits. It enhances transparency and public trust in fire hazard mapping, ensures that wildfire risk information is current and accurate, and strengthens local planning and emergency preparedness. It also provides a meaningful role for local jurisdictions in shaping the final maps.
