Rock Hill, SC Landscaping Rules: Weed Ordinances (2026)

Section 10-292(a) sets a flat 12-inch ceiling on weeds, grass and similar vegetation on any improved residential or commercial lot, three exceptions aside: land actually being farmed or gardened, wooded portions of rear or side yards too dense for standard mowers (except the outer 20-foot strip next to developed property or streets, which must stay mowed), and unimproved lots under active, permitted construction (except the outer ten-foot strip). Vacant, undeveloped lots that abut developed property or a public street face an 18-inch limit on that same 20-foot buffer strip under § 10-292(b).

Subsection (c) treats any lot, improved or not, as a nuisance regardless of the height rules if it holds accumulated debris, rubbish, junk or tires, if growth encroaches over a public sidewalk within eight feet of the walking surface or over a roadway within 14 feet, or if it shows evidence of harboring unlawful activity. Owners must abate a cited violation, and unpaid abatement costs the city incurs become a lien on the property. Enforcement escalates with each repeat violation on the same lot within 12 months: a first offense on residential property draws no fine but a seven-day notice to abate, a second draws $25, a third $50, a fourth $100, and a fifth or later violation draws $250 plus up to $250 per day the violation continues. Commercial, apartment and multi-family property face a flat fine of up to $500 per day of violation starting with the first offense.
