Herndon, VA Landscaping Rules: Grass Height Limits (2026)

Grass height and weed control in the Town of Herndon are regulated under local nuisance abatement authority granted by VA Code §15.2-901 (grass, weeds, and foreign matter) and §15.2-900 (vegetation nuisances). Herndon Town Code requires all owners of improved and unimproved lots to keep grass, weeds, and other rank vegetation from exceeding 12 inches in height on improved residential and commercial properties. On unimproved and vacant lots, the standard may apply to portions within a defined distance of roads, sidewalks, or adjacent occupied properties.

When code enforcement identifies a violation, typically following a complaint, the town issues a notice of violation to the property owner giving a specified period (usually 7 to 15 days) to cut the vegetation and bring the property into compliance. If the owner fails to act, Virginia law and the town code authorize the town to enter the property, cut the vegetation, and bill the owner for the cost of abatement plus administrative fees. Unpaid charges become a lien against the property enforceable through real estate tax collection.

Initial civil penalties typically range from $100 to $250 for a first offense, with escalating fines for repeat violations. Chronic nuisance properties can face additional enforcement including criminal misdemeanor charges. Native plantings, meadow gardens, and pollinator habitats are generally permissible if intentionally maintained and documented, but unmanaged thickets of weeds are not. Residents maintaining naturalized landscapes should submit a management plan to the code enforcement office to avoid violations. Seasonal leaf drop is typically addressed separately through town leaf collection programs, not grass height enforcement.
