Sedgwick County, KS Property Maintenance: Vacant Lot Maintenance (2026)

A. " The same subsection places the eradication duty squarely on the property owner: "It shall be the duty of persons to control the spread of and to eradicate all species of plants declared to be noxious weeds on all lands owned or supervised by them," using official control methods approved by the secretary. That duty attaches to a vacant, unimproved lot exactly as it does to a farm field or a mowed yard; the statute does not exempt undeveloped land. Subsection (d)(1) gives the Sedgwick County Board of County Commissioners its own power to expand the list: with the secretary's approval, the board may publish additional species to be controlled countywide, and any plant so listed "shall be considered a noxious weed within the boundaries of that county" even if the state has not declared it noxious elsewhere.

A. 2-1320 governs the bill: unpaid costs of labor, material and equipment draw a 10 percent penalty after 30 days' notice, and the whole unpaid balance, penalty and interest at the delinquent-tax rate becomes a lien against the property, collected the same way as unpaid property taxes and payable in full before the land can be sold or transferred. Locally, Sedgwick County also regulates general overgrown vegetation on any lot through its own nuisance code (Sedgwick County Code Ch. 19), which sets an 18-inch height trigger separate from the state noxious-weed list; the two regimes overlap but are not the same statute.
