Very High Fire Hazard Severity Zone
Updated 2026-07-18
Very High Fire Hazard Severity Zone is California's highest mapped fire-hazard severity classification. Parcels in this zone may face wildfire construction, vegetation-management, disclosure, access, water-supply, and local planning requirements.
What it means
The classification reflects modeled wildfire hazard from fuels, topography, weather, and fire behavior. It applies through state or locally adopted mapping.
Why it matters for land decisions
Very High status can materially affect project design, approval cost, insurability, and ongoing maintenance.
- Check current official mapping.
- Review local fire code conditions.
People also ask
Does Very High status prohibit building?
Not by itself, but development must satisfy applicable planning, fire, building, access, and water requirements.
Can local maps differ from CAL FIRE recommendations?
Local Responsibility Area maps are adopted through a statutory process, so confirm the effective local map.
