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.
Sunnyvale FAQ
Does Sunnyvale require 100 feet of defensible space?
No, Sunnyvale is not in a state-designated fire hazard zone, so the 100-foot defensible space law does not apply. Standard weed abatement still applies.
What happens if I ignore the abatement notice?
The city will contract the work and place the cost on your property tax bill, plus administrative fees.
