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

Under Virginia Code Section 15.2-901, the City of Fairfax is authorized to regulate grass and weeds on private property, and the city's property maintenance code sets a 12-inch maximum height for grass, weeds, and foreign growth on occupied and vacant lots. Overgrown vegetation is considered a public nuisance because it harbors rodents, insects, and snakes, and poses a fire hazard during dry periods. When code enforcement identifies a violation, the city issues a written notice to abate, typically giving the property owner 7 to 10 days to bring the property into compliance. If the owner fails to act, the city may contract to mow the property and bill the owner for the cost of mowing plus an administrative fee, which becomes a lien against the property if unpaid. Repeat violations within a 24-month period may be cited as Class 3 misdemeanors. The ordinance generally exempts established natural areas, certified pollinator gardens, designated meadow conservation areas, and actively farmed agricultural land, though these exemptions are narrowly construed. Native plant landscaping, rain gardens, and intentional naturalized areas are generally acceptable if maintained and clearly distinguished from neglect. Vacant lots and rental properties are common sources of violations; landlords remain responsible for grass maintenance even when tenants occupy.
