Kootenai County does not set a maximum grass height, but Idaho Code 22-2407 makes every landowner responsible, at their own cost, for controlling noxious weeds on their property. The county Noxious Weed Control Office inspects and advises.
For the unincorporated county there is no numeric lawn-height limit. The binding rule is Idaho's noxious weed statute: Idaho Code 22-2407 places the duty and the cost of controlling state-listed noxious weeds on the landowner. Kootenai County's Noxious Weed Control Office inspects properties, notifies owners of their obligation, and supports mowing as a control and containment method, but under Idaho landowner-rights protections it generally cannot compel spraying. General lawn grass that is not a listed noxious weed is not regulated by the county in unincorporated areas. Cities such as Coeur d'Alene and Post Falls set their own tall-grass and weed ordinances within their limits.
Noxious weed control is the landowner's obligation at their own cost under Idaho Code 22-2407; the county Noxious Weed Office inspects and can require control of listed noxious weeds.
