Grass Height – On April 14, 2025, the Department of Code Compliance (DCC) began accepting reports of grass height over 12 inches. DCC will take reports through mid-October. Chapter 119 of the Fairfax County Code states grass must not be 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
• any commercial or industrial property that is developed but unoccupied (has a building but no tenant).

We support a healthy natural ecosystem for wildlife and pollinators and remind you that trees, shrubs, ornamental grasses, flowers, and other managed landscaping are not subject to enforcement.

Since lot size determines if a residential lot must meet grass height limits, the county’s real estate assessment website can help find lot size, among other information.

Tell us how we’re doing! DCC is asking for your feedback on our operations. Please take a few minutes to complete this questionnaire and help us improve service for the community.

DCC is here to help – if you have questions, want to make a report, or if you are the subject of enforcement and need to contact us. You can report problems online, learn about what happens during an investigation, reach us via email, phone (703-324-1300 / TTY 711), or visit us in person at 12055 Government Center Parkway, Suite 1016, Fairfax, VA 22035.
