Per Noblesville Code § 93.05, a 'weed' is defined as any plant — excluding ornamental grass — exceeding six (6) inches in height. Property owners and tenants must cut high weeds and remove debris within five (5) days of written notice from the Planning Department. The ordinance applies city-wide, including the area between street and sidewalk adjacent to the property. Indiana DNR also enforces 312 IAC 18-3-25, which designates 44 species as prohibited invasive terrestrial plants and bans their sale, gift, transport, or introduction in Indiana.
Noblesville's weed framework has two layers: (1) Local — § 93.05 defines a weed by height (any plant > 6 inches, excluding ornamental grass), making maintenance enforceable regardless of species. Notice triggers a 5-day cure period; the City then abates under § 93.05's entry authorization, with costs billed to the owner. § 93.07 covers the notice procedure and § 93.99 the general penalty. (2) State — 312 IAC 18-3-25 (the Terrestrial Plant Rule, effective April 18, 2019 under IC 14-24) prohibits 44 invasive species statewide, including Japanese honeysuckle, autumn olive, multiflora rose, Bradford/Callery pear, burning bush, Japanese stiltgrass, common buckthorn, glossy buckthorn, garlic mustard, and tree of heaven. It is illegal to sell, gift, barter, exchange, distribute, transport, or introduce these plants in Indiana. Property owners discovering listed species should report them to the Indiana DNR Division of Entomology and Plant Pathology (402 W. Washington St., Room W290, Indianapolis 46204). The rule was phased in: introduction of species not already in Indiana was banned April 18, 2019; species already in trade became prohibited April 18, 2020.
Violations of § 93.05 — not cutting weeds above 6 inches or not removing debris within 5 days of notice — trigger City abatement (entry, cut, bill the owner) and per-day penalties under § 93.99. Costs may attach as a property lien. Possessing, selling, or transporting any of the 44 prohibited species under 312 IAC 18-3-25 may trigger civil penalties from the Indiana DNR Division of Entomology and Plant Pathology and stop-sale orders for nurseries and landscape contractors.
