Fire Hazard Severity Zones
CAL FIRE designates three levels: Moderate: Fire risk exists but is lower than average. High: Significant fire risk based on vegetation, terrain, and weather. Very High (VHFHSZ): The greatest wildfire risk. Special building codes and defensible space requirements apply.
How Zones Are Determined
Factors include: slope and terrain, vegetation type and density, fire weather (wind, humidity, temperature), proximity to fire-prone areas, historical fire activity, and fire behavior modeling.
Impact on Homeowners
Properties in Very High zones face: stricter building codes for new construction, mandatory defensible space requirements, potential difficulty obtaining insurance, higher insurance premiums, and disclosure requirements when selling.
