Summary
Shawnee County's weed nuisance ordinance carves out a specific exception for vegetable and flower gardens: General Code Sec. 23-30(a)(1) exempts them from the county's 18-inch weed-height nuisance standard, but only if the garden is kept looking cared for, free of state-defined noxious weeds, and built within the code's fencing and setback lines.

Full Breakdown
Shawnee County's nuisance ordinance (General Code Chapter 23, Article II) presumes a nuisance exists on platted lots, and on unplatted parcels of four acres or less with a residence, when 'rank grass, weeds, or other obnoxious vegetation' reach at least 18 inches in height. Sec. ' Both exceptions come with a maintenance condition: the code requires the planting be kept 'in a manner so as to appear cared for or cultivated,' and lists the evidence code enforcement looks for: proper pruning, mowing and trimming, separation barriers or marked borders, removal of unattended vegetation, adequate watering, and the absence of any noxious weed as defined by state law.
A front yard garden that has gone to seed and reads as abandoned loses the exemption and reverts to a weed nuisance under Sec. 23-30. The section also requires that 'all such landscaping shall conform to the fencing and setback regulations provided in the Code and the County Zoning Regulations as amended,' so a garden bed enclosed by a fence still has to meet the county's separate fence-height and yard-setback rules. The provision was last amended by Res. No. HR-2025-2, Sec. 4, adopted October 20, 2025, which rewrote the maintaining/permitting-nuisance-conditions list General Code Sec. 23-30 sits in.
Violations & Fines
Sec. 23-34 lets any law enforcement officer, code enforcement officer, the county weed department, or the health department investigate a suspected nuisance. A first conviction for maintaining or permitting a nuisance carries a fine up to $500.00, a second up to $1,000.00, and a third or later violation up to $1,500.00, plus a court order to abate within 30 days; unpaid abatement costs become a lien against the property.
