Leesburg Zoning Overview

Leesburg is a historic town in Loudoun County, Virginia, with approximately 52,000 residents. Founded in 1758 and named for the Lee family of Virginia, Leesburg serves as the county seat of Loudoun County and has grown rapidly as a major DC suburb in Northern Virginia's "Technology Corridor." The Town of Leesburg manages land use and development through its own zoning ordinance, which is separate from Loudoun County's unincorporated area regulations.

The town follows the Virginia Uniform Statewide Building Code (USBC), based on the International Building Code (IBC) and International Residential Code (IRC). Leesburg's zoning divides the municipality into districts regulating permitted uses, building heights, lot sizes, setbacks, and density. A significant feature of Leesburg's regulatory environment is its Historic District overlay, which applies to the original town core and requires design review for exterior alterations and new construction to preserve the town's 18th- and 19th-century architectural character.

Primary Zoning Districts

Leesburg's zoning code includes several residential districts. The R-1 (Single-Family Residential Low Density) district requires a minimum lot size of 20,000 square feet with setbacks of 35 feet (front), 10 feet (side), and 35 feet (rear). The R-2 district allows 10,000 square foot minimum lots, while the R-4 district allows 6,000 square foot minimum lots for higher-density single-family development. The TH (Townhouse) district accommodates attached dwellings with minimum unit sizes of 1,800 square feet.

Commercial activity is concentrated in the B-1 (Community Business) and B-2 (General Business) districts, which serve both neighborhood and highway-oriented commercial needs. The downtown core also has specific historic district overlay regulations that shape the scale and design of commercial development.

ADU (Accessory Dwelling Unit) Rules

Virginia has no enacted statewide ADU preemption. SB 304 of 2024 would have required ADUs by-right but was deferred to the Virginia Housing Commission. Va. Code § 15.2-2292.1 governs only temporary family health-care structures, not general ADUs. ADU rules are set by local zoning ordinance — contact the local planning department.

Development Process

Development in Leesburg generally requires obtaining appropriate permits from the town's planning and building departments. The process typically involves:

1. Zoning Verification — Confirm that your proposed use is permitted in the applicable zoning district
2. Historic District Review — If in the Historic District overlay, obtain Board of Architectural Review approval for exterior changes
3. Site Plan Review — For larger commercial and multi-family projects, submit a site plan for review
4. Building Permit — Apply for a building permit with construction documents
5. Inspections — Schedule required inspections during construction
6. Certificate of Occupancy — Obtain final approval before occupying the structure

Key Considerations

Before starting any development project in Leesburg, property owners should:

• Verify the zoning classification of their property
• Check whether the property is within the Historic District overlay
• Review setback, height, and lot coverage requirements for their specific district
• Determine if the property is in a FEMA flood zone using FEMA's flood map service
• Confirm whether HOA covenants or deed restrictions apply
• Contact Planning & Zoning at (703) 771-2765 for pre-application guidance
