Antioch FAQ
Is my Antioch property in a Fire Hazard Severity Zone?
Check the CAL FIRE FHSZ viewer at osfm.fire.ca.gov. Hillside lots on the city's southern and eastern edges are most likely to be mapped High or Very High FHSZ.
What if my 100-foot zone crosses my property line?
PRC 4291 requires you to clear what you legally can on your own property and coordinate with neighbors. You cannot enter or clear a neighbor's land without permission.
Pittsburg FAQ
Does my home in downtown Pittsburg need defensible space?
Urban-core properties in Local Responsibility Area have reduced requirements but should still follow weed abatement rules and Zone 0 ember-resistant practices for best protection.
What goes in Zone 0, the first five feet?
Zone 0 should be non-combustible: gravel, pavers, or bare soil. Remove wood mulch, stored firewood, patio furniture cushions, and flammable plants within 5 feet of any structure.
Who inspects my defensible space?
The Pittsburg Fire Department and CAL FIRE conduct inspections, especially before fire season. You can request a free defensible space advisory inspection.
