Honolulu FAQ
How do I know if I am in a wildfire zone?
Check Hawaii Wildfire Management Organization maps and HFD outreach materials. Most leeward Oahu neighborhoods near undeveloped slopes face elevated risk and benefit from defensible-space planning.
What is defensible space?
It is the buffer between your home and surrounding vegetation, typically 30 feet of trimmed, low-fuel landscaping that slows fire spread and gives firefighters room to defend the structure.
Urban Honolulu FAQ
Are any Urban Honolulu neighborhoods designated as Hazardous Fire Areas?
The Honolulu Fire Chief can designate areas based on conditions. Hillside neighborhoods bordering open space are most commonly included. Contact HFD Fire Prevention to confirm a specific address.
What does the Chief restrict during red flag warnings?
Restrictions can include open burning, outdoor smoking, fireworks, welding, grinding, and operation of equipment that could produce sparks within designated hazardous fire areas.
