Where the rules live
The primary municipal rules that affect ADUs are in the City of Alexandria zoning and building regulations and the consolidated City Code; specifics about allowable unit types, occupancy limits, and development standards are located in the municipal code and zoning materials [1].
Planning requirements and zoning
Before submitting a building or zoning application, verify that your property’s zoning district allows an ADU and review any lot, setback, height, parking, and occupancy limits. Typical planning steps include a zoning verification, possible variances or special use approvals if the lot does not meet standards, and coordination with historic district review when applicable.

- Confirm development standards and timeline expectations.
- Request a pre-application meeting with Planning & Zoning.
Permit, inspections and building standards

Submit construction documents that show compliance with the Virginia Uniform Statewide Building Code as adopted by the city, plus any Alexandria-specific amendments.
