Honolulu FAQ
Is there a specific grass height limit throughout my entire lot?
The code specifically targets flammable weeds over 18 inches within 30 feet of structures as a defined nuisance; general overgrowth is also subject to abatement orders if it creates a public nuisance.
What happens if I ignore the city's weed-clearance notice?
After 30 days, the city can hire crews to clear the property and bill you for all costs plus 7% interest annually. The unpaid bill becomes a lien on the property.
Waipahu FAQ
My Waipahu lot shares a fence with three neighbors. Who complains first?
Any neighbor or passerby can report to DPP. Notices go to the property owner of record, regardless of which neighbor filed the complaint.
Does ROH Chapter 16A apply to community gardens?
Yes. Any parcel, including community gardens, must avoid fire hazards and vermin harborage. Maintained beds and clear pathways typically satisfy the standard.
