Clark County, NV Landscaping Rules: Weed Ordinances (2026)

Clark County Code Title 10 Chapter 10.30 targets noxious weeds and tumbleweed accumulation at any height that presents a fire or pest hazard, with a general residential threshold of 6 inches. Russian thistle (tumbleweed), puncture vine (goathead), cheatgrass, and Sahara mustard are specifically listed as noxious species and must be removed before they go to seed. Vacant lots over half an acre are inspected seasonally by Code Enforcement and typically abated annually. Beyond weed height, Clark County Department of Environment and Sustainability Regulation 41 (Air Quality) requires any disturbed surface over 5,000 square feet (roughly a single-family lot) to obtain a Dust Control Permit if grading, blading, or weed abatement would generate PM-10 fugitive dust. This is a long-standing rule because the Las Vegas Valley is a federal PM-10 nonattainment area. Residential abatement of small yards generally falls under a permit exemption, but tractor disking or large-scale clearing requires a permit, approved dust control plan, water trucks, and soil stabilizers. Fines for unpermitted dust can reach 10,000 dollars per day and are separate from Title 10 weed citations.
