Loudoun County, VA Special Events & Permits: Block Party Permits (2026)

Block parties and neighborhood events in Loudoun County fall under the county's Special Events permitting framework managed by the Office of Emergency Management, Safety and Security. Events requiring temporary street closures on VDOT-maintained roads need both a county Special Event Permit and VDOT approval for the traffic control plan. Applications are submitted through the LandMARC online portal. However, many Ashburn block parties occur on private HOA streets or common areas, which may only require HOA board approval rather than a county permit — this varies by community. Events with fewer than 50 attendees on private property generally do not need county permits unless they involve temporary structures, amplified sound, or food vendors. Food vendors at any event must obtain temporary food permits from the Loudoun County Health Department regardless of event size. The county does not charge permit fees for small neighborhood gatherings. Loudoun County's seven incorporated towns (Leesburg, Purcellville, etc.) have separate event permit requirements — Ashburn as an unincorporated area falls under county jurisdiction.
