Full Breakdown

Under the Fire Prevention Code, any weeds, grass, vines, or other growth capable of being ignited and endangering property must be cut down and removed by the owner or occupant. Once such vegetation exceeds 12 inches in height and the fire code official determines it's a fire hazard, the owner is notified by certified mail or in person and given a deadline to clear it. If the owner fails, neglects, or refuses to abate the hazard, the fire code official can order the abatement done and recover the cost as a lien on the property or as a city tax under Idaho Code 50-1008. Structures in designated Wildland-Urban Interface areas face additional, stricter clearance rules under BCC Chapter 41.

Violations & Fines

Failure to abate after notice lets the city clear the vegetation itself and bill the owner via a property lien or city tax under Idaho Code 50-1008; general fire code violations are misdemeanors up to $1000 and/or 6 months.
