Honolulu FAQ
Do I need to remove all plants within 30 feet of my house?
Not all plants. Single ornamental trees or ground covers that do not transmit fire to native growth are exempt; flammable brush and dry vegetation must be cleared.
Can the Fire Department require me to clear more than 30 feet?
Yes. In areas with hazardous fire conditions the HFD can require clearance from 30 up to 100 feet from structures.
Kailua FAQ
Does brush clearance apply to flat Kailua beachfront lots?
Generally no unless the parcel is in or adjoins a designated hazardous fire area. Maunawili and Olomana adjacent lots are more likely to be covered.
Who decides when the 100-foot rule applies?
The AHJ (HFD fire chief) can designate hazardous conditions and impose the expanded clearance through written notice to the owner.
