Grass Height - On April 15, 2024, the Department of Code Compliance (DCC) began accepting reports of grass height over 12 inches. DCC will continue taking reports through mid-October. Chapter 119 of the Fairfax County Code requires that grass be no taller than 12 inches on:

• residential property that is developed (has a house) and is less than a half-acre (21,780 square feet);
• undeveloped residential property less than one-half acre, if 90% of the lots in the subdivision have houses; and
• commercial and industrial properties of any size that are developed but unoccupied (have a building but no tenants).

Managed landscaping is not subject to enforcement, which includes trees, shrubs, ornamental grasses, and flowers. Thinking about adding these features to your lawn or garden? Check out the Park Authority’s website for more information on planting for pollinators.

Since the 12-inch grass height limit may depend on lot size, you can use the county’s map website for help finding lot size and more. Also, DCC’s grass height website has more information about the regulations, exemptions, and what DCC does if property owners do not voluntarily cut their grass (see under How are these Rules Enforced?)
