The California Board of Forestry and Fire Protection has approved new regulations to mitigate wildfire risks by establishing ‘Zone Zero’ (or ‘Zone 0’), a critical ember-resistant perimeter surrounding homes. These mandates target properties within State Responsibility Areas and Very High Fire Hazard Severity Zones.

The rules require the removal or modification of combustible materials—including firewood, wood chips, bark mulch, vines, and dead vegetation—within a five-foot radius of structures. Specific vegetation management includes clearing materials within one foot of a structure or up to the roof eave, and ensuring tree branches are trimmed at least five feet above roofs and ten feet away from chimneys.

While the regulations apply to new constructions immediately, existing homeowners are granted a phase-in period. Implementation timelines for existing homes vary, with some requirements, such as clearing debris from gutters and trimming trees, to be completed within three years, while other regulations allow for a five-year window.

To complement these landscaping mandates, California is integrating technological measures for early detection. The ALERTCalifornia program, a collaboration between UC San Diego and state agencies like CAL FIRE, utilizes a network of over 1,200 high-definition cameras. These cameras employ artificial intelligence to analyze images for smoke and potential fire starts, providing real-time data to emergency responders.
