Vienna, VA Fire Regulations: Brush Clearance (2026)

The Town of Vienna does not have a defensible space ordinance in the Western U.S. sense. Vienna is a fully developed suburban community in the Washington DC metropolitan area with municipal water supply, hydrants, a professional fire department (Fairfax County Fire and Rescue Station 2), and no significant wildland-urban interface. Virginia does experience occasional wildfires, primarily in western mountain counties, but Fairfax County is classified as low wildfire risk. General property maintenance provisions in the Vienna Town Code require owners to remove dead, diseased, or hazardous trees; keep vegetation from becoming a nuisance; and avoid accumulating combustible debris such as brush piles, old lumber, and trash. The SFPC requires that weeds, grass, vines, or other growth capable of being ignited and endangering property be cut down and removed by the owner, particularly within ten feet of buildings and along property lines. Chimneys should have approved spark arrestors, and firewood stacks should be kept away from structures. During Virginia Department of Forestry burn bans, all outdoor burning including recreational fires may be suspended. Homeowners concerned about ember risk from a house fire in close-set neighborhoods can voluntarily follow Firewise USA principles: clear gutters of leaves, trim branches away from roofs, keep a noncombustible zone within five feet of the foundation, and store firewood at least thirty feet from the house. These are best practices rather than mandates in Vienna. Properties adjoining stream valley parks or large wooded parcels should pay particular attention to dead fuel loads and overhanging branches.
