Ames, IA Landscaping Rules: Native Plants (2026)

Ames's rule on native landscaping lives inside Chapter 30, Public Nuisances, which applies citywide under Sec. 30.2's scope clause covering all properties within the City of Ames. Sec. 30.4 defines Turf Grasses specifically as narrow-leaved species forming a mowed, traffic-tolerant ground cover of two inches or below, and Sec. 30.5(11) makes only turf grasses exceeding 12 inches in height a nuisance, so a deliberately planted native or prairie bed that is not turf grass falls outside that height trigger as long as it stays a managed planting rather than an abandoned lot.

The City goes further in the right-of-way: Sec. 30.5(8) caps vegetation there at 12 inches within a foot of the traveled street but expressly exempts areas approved by the City as stormwater or native vegetation preservation areas, meaning a homeowner who gets City sign-off can keep taller native plantings even along the boulevard strip. Ames's separate Rental Housing Code (Sec. 13.406(9)(b)) uses a parallel test for rental properties, defining weeds as vegetation that is not purposefully planted, cultivated and managed, or that has been allowed to proliferate uncontrolled, so a tended native garden again escapes the weed label there too.

Enforcement citywide runs through the City Manager's designated enforcement officer under Sec. 30.3, which authorizes abatement by municipal infraction, and violations not corrected after written notice under Sec. 30.7 can be abated by the City with costs assessed against the property like a special tax. Owners who dispute a nuisance finding can request a hearing before the seven-member Public Nuisance Appeals Board under Sec. 30.8.
