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.
Pearl City FAQ
Who is responsible if a Pearl City rental's yard is overgrown?
The property owner is ultimately responsible under ROH Chapter 16A, even when tenants occupy. Landlords should specify yard care duties in the lease.
Do condos and townhomes receive weed notices?
Notices typically go to the association or common-area owner. Individual owners of attached units are rarely named directly for shared landscape areas.
