Summary
Idaho Code 22-2407 makes it every landowner's duty to control noxious weeds, enforced in unincorporated Ada County by the county weed superintendent under Title 22, Chapter 24. Ada County has no fixed grass-height number in county code; incorporated cities set their own weed and grass limits.
It shall be the duty and responsibility of all landowners to control noxious weeds on their land and property, in accordance with this chapter and with rules promulgated by the director.
Full Breakdown
Weed control in Idaho is driven by state law. Idaho Code 22-2407 places the duty to control noxious weeds on every landowner, and Ada County Code Chapter 8 (Noxious Weed Control) implements this through a county weed superintendent who may inspect, notify, and abate. Unlike many cities, unincorporated Ada County does not set a numeric grass-height limit in county code; tall grass is addressed primarily through the noxious-weed program and the general nuisance ordinance. Residents inside Boise, Meridian, Eagle, Kuna, or Star should check their city code, which typically imposes a specific grass-height limit (often 6-12 inches).
Violations & Fines
If a landowner fails to control noxious weeds after notice, the county weed superintendent may abate the weeds and assess the cost against the property under Idaho Code Title 22, Chapter 24.
