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.
