Summary
Kansas City, Kansas and the rest of Wyandotte County cap weeds, grass, and uncultivated vegetation at eight inches tall, or 12 inches matted down, under Code §§ 8-534 and 8-535. Letting a lot exceed that height is unlawful, and the unified government can mow it and bill the owner after a short cure period.
Excessive growth or hazardous premises means any weed, grass or uncultivated vegetation which is more than eight inches in height above the ground or 12 inches in length, if matted down, as measured along the stem... It shall be unlawful for any property owner, representative, tenant or other person with control, occupancy or possession of real property to allow excessive growth of vegetation on any lot or parcel of land within the city or in any area between the property lines of said lot or parcel and the centerline of any adjacent street or alley.
Full Breakdown
Section 8-535 makes it unlawful for any property owner, representative, tenant or other person with control, occupancy or possession of real property to allow excessive growth of vegetation on any lot or parcel of land within the city or in any area between the property lines of said lot or parcel and the centerline of any adjacent street or alley. Section 8-534 defines excessive growth as any weed, grass, or uncultivated vegetation more than eight inches in height above the ground or 12 inches in length if matted down, and extends the rule to trees, shrubs, and garden plants that aren't kept visually distinct from surrounding overgrowth.
Enforcement runs through Sections 8-536 through 8-543. The unified government clerk publishes an annual public notice explaining the standard, and once a violation is confirmed, the occupant, owner, or agent gets five days to cut it, ten days if the owner is unknown or a nonresident without a resident agent, or to request a hearing before a designated hearing officer under Section 8-541. Skip both options and the unified government's crews or contractors cut the lot under Section 8-542, then bill the cost, including administrative fees, under Section 8-543; unpaid bills become a special assessment on the property tax roll or, after a year, a personal debt collectible in county district court with statutory interest under K.S.A. 79-2968. A property flagged as a perennial violator can be mowed without any further individual notice for the rest of the calendar year.
Violations & Fines
Section 8-539(a)(9) makes a violation of this article a misdemeanor carrying a fine of not less than $100.00 nor more than $1,500.00, with each day the excessive growth continues counted as a separate offense. Prosecution does not limit the unified government's separate right to abate the growth itself and recover its removal and administrative costs from the owner.
