California Adopts Nation's Toughest Home Vegetation Rules For Wildfire Zones
On August 19, 2026, the California Board of Forestry and Fire Protection approved Zone Zero rules banning most vegetation within five feet of homes in wildfire-prone areas.[1]
The rules allow only low, non-woody plants in that five-foot zone and require tree branches to be trimmed five feet away from structures.[1] They take effect immediately for new construction and will be phased in for almost 2 million existing homes in high-risk zones.[1] Regulators said the measures rest on research showing ember-driven home ignitions and warned that more than 57,000 structures were destroyed by wildfires in California over the past decade.[1]
State fire scientists and the board pointed to studies that found burning embers blown ahead of flames often ignite landscaping, roofs and vents, turning houses into fuel.[1] Officials framed the new rules as the toughest in the nation for home landscaping in wildfire zones.[1]
Board members approved the regulations after a meeting on Wednesday and said state agencies will work with local governments on enforcement and outreach.[1]
