Palo Alto FAQ
Is my Palo Alto property in the VHFHSZ?
Check the CAL FIRE FHSZ map or Palo Alto hazard layer. Most flatland homes east of I-280 are not in the zone, while foothill parcels typically are.
What happens if I fail inspection?
The Fire Department issues a notice with a deadline. Non-compliance can lead to city-hired abatement billed to the property.
Santa Clara FAQ
Is Santa Clara in a fire hazard zone?
Most of the city is classified as Local Responsibility Area outside any Very High Fire Hazard Severity Zone, but individual parcels near foothills or open space may still require defensible space.
What if I ignore a weed abatement notice?
The city or county can abate the hazard and place a lien on the property for the cost plus administrative fees.
