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.
