Kootenai County, ID Property Maintenance: Vacant Lot Maintenance (2026)

Idaho Code 22-2407, which governs vacant, unimproved and every other parcel in the county, puts the 'duty and responsibility' to control noxious weeds squarely on 'all landowners,' in accordance with the rules the state director of agriculture adopts, and makes the cost of that control 'the obligation of the landowner' even when the county or its control authority does the work. Control must aim at prevention, eradication, rehabilitation or containment, though a landowner enrolled in a county-approved weed management plan or cooperative weed management area can get the eradication requirement modified for a vacant or hard-to-maintain lot.

If a landowner ignores a five-day notice served under Idaho Code 22-2405, the county control authority can enter the property, do the work itself, and the landowner must reimburse every dollar spent; unpaid charges after sixty days become a lien on the land, collectible the same way as delinquent property taxes. The county's general notice for weed control runs in a local newspaper every year between March 1 and April 30 under 22-2405(2), listing the county's noxious weeds and stating the obligation to control them, and that published notice alone is legally sufficient even if no individual notice is ever mailed to a vacant lot's owner.

Owners do get a say: Idaho Code 22-2408 lets anyone dissatisfied with a control charge, or with the control methods used on their land, file a protest with the director within thirty days, and anyone served an individual notice can appeal to the board of county commissioners within two days of receiving it, triggering a hearing within five days. If an article on the lot, such as harvested hay or equipment, is infested, 22-2407(5) bars moving it off the premises until it's treated or the control authority gives written permission.
