Iowa City, IA Landscaping Rules: Weed Ordinances (2026)

City Code section 6-3-1 defines 'weeds' as any uncultivated plants growing out of context with surrounding vegetation that reach ten inches (10") in height or that have formed or are forming a seed head, and defines an 'unmowed or untended area' the same way. Section 6-3-2(B) makes every owner and every person in possession or control of a developed or undeveloped lot responsible for keeping that lot, plus the adjacent parking strip, alley and public way up to the centerline, free of weeds and mowed so grass stays under 10 inches.

Subsection A separately requires cutting or destroying 'noxious weeds' (the primary and secondary weed classes set by state law) in whatever manner the City's weed official prescribes, subsection C bars any plant growth that blocks pedestrian or vehicle travel on adjoining streets and sidewalks, subsection E extends the 10-inch limit to the banks of any waterway crossing the lot, and subsection F prohibits plant growth or debris that creates a fire hazard as determined by the fire marshal. Section 6-3-4 lets the weed official, fire marshal or city engineer order immediate abatement without prior notice when uncontrolled growth creates a health, safety or fire hazard, then bill the cost to the property like a tax after giving the owner written notice and a hearing opportunity. Section 6-3-5 makes any violation of the chapter a municipal infraction under subsection 1-4-2D.
