Fontana FAQ
How do I find out if my Fontana address is in a high fire zone?
Use the CAL FIRE Fire Hazard Severity Zone Viewer online - enter your address to see your zone classification.
Do all Fontana homes need Chapter 7A materials?
No. Chapter 7A applies only to new construction or substantial remodels within a Fire Hazard Severity Zone, primarily the foothill neighborhoods.
Will my home insurance be affected by the fire zone rating?
Yes. VHFHSZ designation often raises premiums and can lead to nonrenewal; completing defensible space inspections helps maintain coverage.
Victorville FAQ
Is my Victorville home in a wildfire zone?
Many Victorville parcels are on the desert floor outside VHFHSZ, but foothill and wildland-interface neighborhoods are mapped. Always verify on the CAL FIRE FHSZ viewer for your specific address.
Do I need Chapter 7A ignition-resistant siding in Victorville?
Only if your parcel is mapped in a Very High Fire Hazard Severity Zone. New construction and major rebuilds in those zones must use Class A roofing, ember-resistant vents, and approved exterior materials.
