Hawai'i County has no fixed grass-height number. Overgrown lots are handled as public nuisances: under HRS 46-1.5(12) the county may compel clearing of uncultivated undergrowth from unoccupied lots and bill or lien the owner if they ignore notice.
Unlike mainland cities, the County of Hawai'i sets no specific inches-of-grass limit island-wide. Enforcement runs through the state's nuisance grant (HRS 46-1.5(12)), which lets the county 'summarily remove public nuisances' and 'compel the clearing or removal of any public nuisance, refuse, and uncultivated undergrowth from streets, sidewalks, public places, and unoccupied lots.' The county must first define the nuisance by ordinance/rule, give reasonable notice, and may then clear the lot and lien the property for the cost. There is no municipal government below the county, so the county alone regulates this.
After reasonable written notice, the county may clear the lot and impose and enforce a lien on the property for the cost of the work.
