Fire Hazard Severity Zone Map

Fire Hazard Severity Zone Map (FHSZ) Update

The State Fire Marshal is responsible for identifying 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. As part of this requirement, CAL FIRE has made recommendations for Local Responsibility Areas (LRA) that were rolled out on March 24, 2025. All State Responsibility Areas were addressed in 2024.

You can view the map via the link below or at our Administrative Office, located at 14011 City Center Drive, Chino Hills during the posted business hours. Please note that state law prohibits the Fire District from assigning a fire hazard severity zone that is less restrictive than the one recommended by the State Fire Marshal.

What requirements did the Fire District  have to follow regarding the fire hazard severity maps?

Per California Government Code, the Fire District was required to make the information available for public review and comment within 30 days of receiving the map and within 120 days, the Fire District must designate, by Ordinance, moderate, high, and very high fire hazard severity zones.

The Fire District received the maps on March 24, 2025. The public comment period closed on April 30, 2025.  At the May 14, 2025, Board of Directors meeting, Ordinance 2025-01 was introduced and a first reading was held.  At the July 9, 2025, Board of Directors meeting, a Public Hearing was held related to the new Ordinance and a second reading was conducted.  The Board of Directors adopted said Ordinance with an effective date of September 1, 2025.   

What requirements must property owners comply with, if they live in a designated fire hazard severity zone? 

  • If your property is in the very high FHSZ, you are legally required by Government Code and CVFD Ordinance 2022-01 to comply with defensible space requirements. In addition, upon sale of the property you are required to comply with the hazard disclosure requirements. For any new construction or additions, it would be required to comply with building standards for the wildland urban interface. You are highly encouraged to create a wildfire preparedness plan for you, your family, and your property.
  • If your property is in the high FHSZ, you are legally required by the CVFD Ordinance 2022-01 to comply with defensible space requirements. In addition, upon sale of the property you are required to comply with the hazard disclosure requirements. For any new construction or additions, it would be required to comply with building standards for the wildland urban interface. You are highly encouraged to review and create a wildfire preparedness plan for you, your family and your property.
  • If your property is in the moderate FHSZ, there are currently no legal requirements. However, you are highly encouraged to review and create a wildfire preparedness plan, as you can be impacted by wildfire.
