Kailua property owners in or adjacent to hazardous fire areas, such as the Maunawili and Olomana foothills, must clear flammable vegetation within 30 feet of structures and may be required to extend clearance to 100 feet when HFD designates heightened risk.
Brush clearance in Kailua flows from ROH Chapter 20's adoption of NFPA 1 (2021) Section 10.18 on Hazardous Fire Areas. Property owners adjoining undeveloped slopes above Kailua, including areas near Maunawili Valley, Olomana, and the Ko'olau foothills, must maintain a defensible space by clearing flammable vegetation within 30 feet of any building. When HFD's fire chief finds hazardous conditions (dry season, wind-prone ridges, prior fire history), the AHJ may require additional clearance up to 100 feet. Dead branches overhanging roofs and accumulated leaf litter in rain gutters must be removed. Compliance is inspected after complaints or during high-risk wind events.
Failure to comply after notice is a Chapter 20 violation; the City may perform abatement at the owner's expense and add charges as a lien on the property.
