Alexandria Zoning & Land Use Guide
Key Zoning Facts
Alexandria Zoning Overview
Alexandria is an independent city in Virginia with approximately 159,467 residents. As an independent city, Alexandria is not part of any county and handles all local government functions directly. Located in Northern Virginia near Washington, D.C., the city manages land use and development through its local zoning ordinance, which divides the municipality into districts regulating permitted uses, building heights, lot sizes, setbacks, and density.
Alexandria follows the Virginia Uniform Statewide Building Code (USBC), which is based on the International Building Code (IBC) and International Residential Code (IRC).
Primary Zoning Districts
Alexandria's zoning code includes several residential districts. The R-20 district requires a minimum lot size of 20,000 square feet with setbacks of 40 feet (front), 15 feet (side), and 25 feet (rear). The R-12 district requires 12,000 square foot minimum lots with setbacks of 30 feet (front), 10 feet (side), and 25 feet (rear). The R-8 district requires 8,000 square foot minimum lots with setbacks of 25 feet (front), 8 feet (side), and 20 feet (rear). The R-5 district allows 5,000 square foot minimum lots with setbacks of 20 feet (front), 5 feet (side), and 15 feet (rear). All single-family districts have a 35-foot height limit.
Commercial activity is served by the CL (Commercial Low) and CC (Commercial Community) districts. The I (Industrial) district provides for manufacturing, warehousing, and distribution uses.
ADU (Accessory Dwelling Unit) Rules
Alexandria allows ADUs (Accessory Dwelling Units). Under Virginia Code § 15.2-2292.1 (effective 2024), all Virginia localities must permit ADUs in single-family residential zones. Contact the Alexandria Planning & Zoning department for current requirements including size limits, setbacks, owner-occupancy rules, and permitting procedures.
Development Process
Development in Alexandria generally requires obtaining the appropriate permits from the city's planning and building departments. The process typically involves:
- Zoning Verification — Confirm that your proposed use is permitted in the applicable zoning district
- Site Plan Review — For commercial and multi-family projects, submit a site plan for review
- Building Permit — Apply for a building permit with construction documents
- Inspections — Schedule required inspections during construction
- Certificate of Occupancy — Obtain final approval before occupying the structure
For projects that do not conform to existing zoning, property owners may need to seek a variance, special exception, or rezoning through the local board of zoning appeals or planning commission.
Key Considerations

- Verify the zoning classification of their property
- Review setback, height, and lot coverage requirements for their specific district
