Summary

Loudoun County's Zoning Ordinance exempts ordinary fences from the Zoning Permit that most other structures need before construction. A fence built in the unincorporated county does not require a Zoning Permit unless the lot sits inside one of six protective overlay districts.

These county ordinances apply to unincorporated areas of Loudoun County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Zoning Permits are not required for accessory structures under 30 inches in height and less than 20 square feet in area, fences, and stormwater management improvements, unless located within the Floodplain Overlay District (FOD), Mountainside Overlay District (MOD), Limestone Overlay District (LOD), Historic Overlay District (HOD), River and Stream Corridor Resource (RSCR), or Steep Slopes Areas.

Full Breakdown

A of the Zoning Ordinance makes a Zoning Permit a prerequisite for the issuance of a building permit or certificate of occupancy and for construction of any structure. 2 carves fences out of that requirement by name: Zoning Permits "are not required for accessory structures under 30 inches in height and less than 20 square feet in area, fences, and stormwater management improvements," unless the property is located within the Floodplain Overlay District (FOD), Mountainside Overlay District (MOD), Limestone Overlay District (LOD), Historic Overlay District (HOD), River and Stream Corridor Resource (RSCR), or a Steep Slopes Area.

2 states permit fees are non-refundable. This rule governs only the unincorporated county; Leesburg, Purcellville, Hamilton, Middleburg, Round Hill, Hillsboro and Lovettsville enforce their own town codes and may require a fence permit even where the county would not. Property owners near floodplains, steep slopes or historic districts should confirm overlay status with the Zoning Administrator's office before installing a fence, since the county's GIS parcel viewer flags overlay boundaries that are not always obvious from the road.

Violations & Fines

Building a fence inside a covered overlay district without first obtaining a Zoning Permit is a Zoning Ordinance violation, and Section 10.04.G makes noncompliance with any permit condition a violation as well. The Zoning Administrator can require removal or retroactive permitting, and unresolved violations can be referred for civil penalties under the county's zoning enforcement provisions. Homeowners associations may layer additional architectural-review fence rules on top of the zoning exemption, so a permit-free fence under county rules can still need HOA sign-off.

Frequently Asked Questions

Do I need a permit to build a fence in Loudoun County?
No, not in the unincorporated county. Section 10.04.A.2 of the Zoning Ordinance exempts fences from the Zoning Permit requirement, the same exemption given to small accessory structures and stormwater improvements.
When does a fence in Loudoun County need a permit?
Only if the parcel lies within the Floodplain, Mountainside, Limestone, or Historic Overlay District, the River and Stream Corridor Resource area, or a Steep Slopes Area, per Section 10.04.A.2. Outside those six overlays, no Zoning Permit applies to a fence.
Does this exemption apply in Leesburg or Purcellville?
No. The Zoning Ordinance exemption applies to the unincorporated county. Leesburg, Purcellville, Hamilton, Middleburg, Round Hill, Hillsboro and Lovettsville administer their own town codes and may set different fence permit rules.
