CAL FIRE has updated the State Responsibility Area (SRA) Fire Hazard Severity Zone maps using current wildfire modeling and conditions as part of a statewide effort to improve fire preparedness.
In Palm Desert, some properties may now be classified as Moderate, High, or Very High fire hazard severity zones, which can affect building standards, insurance, and defensible space requirements. The City is reviewing the updated maps and will provide opportunities for public input before adoption.
Under state law (California Government Code §51178), the State Fire Marshal designates fire hazard severity zones based on consistent statewide criteria. CAL FIRE also provides recommendations for Local Responsibility Areas (LRA)—including cities like Palm Desert—where wildfire protection is the responsibility of the local government.
Fire Hazard Severity Zones
- Moderate: Lower likelihood of wildfire ignition and spread
- High: Greater likelihood of ignition and more intense fire behavior
- Very High: Highest potential for ignition, spread, and severe fire behavior

Frequently Asked Questions
What Must the City of Palm Desert do after Receiving These Recommendations?
- Per California Government Code 51178.5, the City must make the updated information available for public review and comment within 30 days.
- Per California Government Code 51179, the City must designate, by ordinance, moderate, high, and very high fire hazard severity zones within 120 days. While there is some flexibility to increase hazard severity zones, they are largely based on the recommendations made by CAL FIRE.
Can the City Change the Fire Hazard Zone Recommendations by CAL FIRE?
- The City may, at is discretion, include areas within its jurisdiction, which are not identified as very high fire hazard severity zones by the State Fire Marshal as very high fire hazard severity zones following a finding supported by substantial evidence.
- The City may, at its discretion, include areas within its jurisdiction, not identified as moderate and high fire hazard severity zones by the State Fire Marshal, as moderate and high fire hazard severity zones, respectively.
- The City may not decrease the level of any fire hazard severity zones as identified by the State Fire Marshal for any area within its jurisdiction.
What are Fire Hazard Severity Zones (FHSZ)?
- FHSZs are classifications developed by CAL FIRE that reflect the potential for wildfire in a given area. They consider vegetation, terrain, weather patterns, and fire behavior models. These zones help inform building standards, emergency preparedness, and mitigation planning.
Why did CAL FIRE Update the Maps?
- The updated maps use modern fire modeling techniques, better data, and reflect current wildfire risks. The last major update was over a decade ago, and conditions have significantly changed due to drought, vegetation growth, and climate shifts.
How do I Find Out What Zone my Property is in?
- Use CAL FIRE’s interactive map tool or check the City of Palm Desert’s map link. Enter your address to view whether your property falls in a “Moderate,” “High,” or “Very High” severity zone.
Does This Change Impact Homeowners' Insurance?
- While the FHSZ itself does not set insurance rates, insurers may consider hazard zones when evaluating coverage. Residents are encouraged to contact their insurance provider for more information.
What Building Regulations Apply to Properties in These Zones?
- Properties in High or Very High FHSZs are subject to California’s Wildland-Urban Interface (WUI) building standards, which may include fire-resistant materials, ember-resistant vents, and defensible space requirements.
Will this Affect Existing Homes or Only New Construction?
- The updated zone maps primarily affect new construction and major remodels, but all property owners are encouraged to maintain defensible space and consider home hardening improvements to reduce wildfire risk.
Can I Appeal or Comment on the FHSZ Classification of my Property?
- Yes. CAL FIRE allows public comment and review during the map adoption process. The City of Palm Desert is also collecting feedback from residents to submit as part of this process. Feedback can be emailed to publicsafety@palmdesert.gov. To contact the State's Fire Marshal directly regarding these changes, you can email FHSZinformation@fire.ca.gov or call (916) 633-7655.
What Does This Mean for me Right Now?
- No immediate changes are required, but it’s important to understand your property’s classification and take steps to prepare for wildfire. The City will provide updates on any new requirements or deadlines as the maps move through the state approval process.
