Lewisville, TX Landscaping Rules: Weed Ordinances (2026)

Lewisville Code of Ordinances Chapter 10 (Health and Sanitation) requires all property owners to keep lots free of weeds, brush, rubbish, and other unsanitary conditions. Weeds exceeding 12 inches in height trigger the same enforcement process as overgrown grass: written notice to the property owner with a deadline to abate, followed by city contractor removal and cost assessment as a property lien if the owner fails to comply. Beyond the height standard, the code also prohibits accumulation of weeds, brush, or vegetation that creates a harbor for rats, mosquitoes, or other vermin, or that presents a fire hazard. This applies regardless of vegetation height. Vacant lots are frequent targets for weed enforcement, particularly during spring growing season (March through May) when North Texas rainfall promotes rapid weed growth. During summer drought, dead weeds become a fire hazard and must also be cleared. Code Compliance accepts complaints through the Lewisville Engage app, online portal, or by phone at (972) 219-3450. Property owners who receive repeated violations may face escalating penalties.
