Before you open any sign ordinance for a Loudoun County job, find out which government the address actually sits in. A shop off Route 7 in Ashburn and a storefront on King Street in Leesburg are a short drive apart, but they answer to different rulebooks, different permit portals, and different staff. The mailing address on the work order will not tell you which one you have.
The rule is in state law, in one sentence
Virginia settles the county-versus-town question directly. Under Va. Code § 15.2-2281, “the governing body of a county shall have jurisdiction over all the unincorporated territory in the county, and the governing body of a municipality shall have jurisdiction over the incorporated area of the municipality.” In Virginia, “municipality” means a city or a town (§ 15.2-102).
Loudoun County says the same thing from its side. Its Zoning Ordinance page notes that the Board of Supervisors adopted the current ordinance on December 13, 2023, and that “the Zoning Ordinance does not apply to properties within the seven incorporated towns. Each town has its own Zoning Ordinance.” Leesburg is one of those towns. Ashburn is not.
The same page lists two exceptions inside the county's own territory. Commercially and industrially zoned properties in the Route 28 Tax District that were administered under the 1972 Zoning Ordinance stay under that ordinance unless the owner waives the district's protections through a rezoning or zoning conversion. And grandfathered applications may continue to approval under the Revised 1993 Zoning Ordinance. For a commercial or industrial lot, or a project with an older application behind it, confirm which ordinance governs the parcel before using the current sign chapter.
Ashburn is a place name, not a government
Ashburn has its own ZIP codes and shows up on every delivery label, so it is easy to assume it has a town hall. It does not. The Census Bureau publishes it as Ashburn CDP, Virginia, and explains that census designated places “represent unincorporated communities that do not have a legally defined boundary or an active, functioning governmental structure.” For a sign in Ashburn, the county ordinance is the local code, subject to the exceptions above.
The trap: a Leesburg address outside Leesburg
The harder case is the reverse. Many addresses outside the town use “Leesburg, VA 20176” or “20175” as their mailing address, including developments that sit well outside the town limits. A crew that sees “Leesburg” on the order and pulls up Leesburg's Article 15 can end up designing to the wrong code and filing in the wrong portal.
We checked three public addresses on September 28, 2026 with the Census Bureau's geographies geocoder. It is free, needs no account, and returns an “Incorporated Places” line when an address falls inside a town or city.
| Address as mailed | Incorporated place returned | Local code to read |
|---|---|---|
| 43316 Hay Rd, Ashburn, VA 20147 (Ashburn Library) | None | Loudoun County Zoning Ordinance |
| 25 W Market St, Leesburg, VA 20176 (Leesburg Town Hall) | Leesburg town | Town of Leesburg Zoning Ordinance |
| 19286 Promenade Dr, Leesburg, VA 20176 (Lansdowne Town Center) | None | Loudoun County Zoning Ordinance |
The third row is the one that catches people. The mailing address says Leesburg; the geocoder finds no incorporated place, so the town ordinance does not reach it. Two details are worth knowing when you read the output. First, the geocoder also returns a “County Subdivisions” line with names like “Ashburn district.” That is a Census statistical area, not a town with its own zoning. The same goes for a “Census Designated Places” line such as “Lansdowne CDP” for the third address: a statistical area, not a government. Second, the geocoder places an address along a street range rather than on the exact parcel, so a lot right on a town line deserves a call to the town or county zoning office before anyone relies on it.
What changes once you know the answer
In unincorporated Loudoun County
The sign rules are Chapter 8 of the Loudoun County Zoning Ordinance (sections 8.01 through 8.11), published by the county as a Chapter 8 PDF. Section 8.10.A is the short version of the permit rule: “If Chapter 8 requires a Sign Permit, the sign is not allowed to be erected without obtaining a Sign Permit pursuant to Section 10.05.” For wall signs, Table 8.05-1 answers “Permit required?” with a Y in every sign-group column, and it counts wall, awning, and projecting signs together against the same allowance. One practical note: the copy we read still carries figure captions marked “[new figure will replace this one],” so check the county's current copy before relying on a diagram.
The county's Sign Permits page, which we read on September 28, 2026, says sign permits are required before installation and that the property owner must sign zoning applications, or provide a notarized affidavit naming who may sign for them. A building-mounted sign needs the sign permit application with two copies of drawings no larger than 8.5 by 14 inches showing the sign's dimensions, its elevation on the building, and its wording. An electric sign adds an electrical permit application with hook-up drawings, filed in the same package. A monument sign, or any other freestanding sign over 20 square feet, also needs a building permit with three sets of architectural drawings and two site plans or plats showing the distance to the right-of-way. The page listed a $235 fee per commercial sign, $10 for a temporary sign, and $65 per sign for the electrical permit, with building permit fees set separately. Fees change; read the page again on the day you file.
Inside the Town of Leesburg
The town's Sign Permits page puts it plainly: “Regulations regarding signs in the Town are outlined in Article 15 of the Town of Leesburg Zoning Ordinance. A separate Sign Permit application is required for each permanent business sign.” Applications go through the town's eTRAKiT portal, with a digital plan set showing size, color, letter style and design, the method of illumination, the exact location with a site diagram, and mounting details for projecting or suspended signs.
Two things on that page change the schedule. (The county has its own versions of both: historic overlay review, and Sign Development Plans under section 8.10.C.) Most signs in the H-1 Old & Historic District, the Gateway District, and the H-2 Historic Corridor District (the town notes H-2 applies by proffer only) need a Certificate of Appropriateness, and the town points applicants to separate historic-district sign guidelines. And a multi-tenant building or shopping center may already have a comprehensive sign plan that governs a new tenant's sign; the town publishes an interactive map of properties that have one. Check both before drawing anything. The town's online code host also shows a zoning ordinance rewrite in draft, so confirm which version is in force when you file.
A third layer on the highway edge
Neither local code settles where the state right-of-way begins. VDOT's outdoor advertising page answers the common question directly: “Signs cannot be on or overhanging state right of way,” citing § 33.2-1224 of the Code of Virginia. The county's requirement that site plans for monument and larger freestanding signs show the distance to the right-of-way is how that line gets onto paper.
The record to keep for a Loudoun job
