Alexandria's Zoning Ordinance Section 6-403 (General Regulations and Exceptions) governs fences in residential zones. Most rear-yard fences are limited to 6 feet, while front-yard fences are limited to about 4 feet. Corner-lot front yards have stricter limits, and some installations require a fence permit through the Department of Planning and Zoning.
Fences in Alexandria are regulated by Zoning Ordinance Article VI, Sec. 6-403. In typical residential districts, rear and side yard fences may reach up to 6 feet in height, while front yard fences are generally limited to roughly 4 feet. On corner lots, by-right fences along the front yard are capped at approximately 3.5 feet, with 6-foot fences allowed on the secondary front only when additional setbacks are met. Even when a building permit is not required, the fence must comply with the Zoning Ordinance, including sight-distance and setback rules. Property owners should confirm zoning district, lot type, and any historic district overlay (Old and Historic Alexandria, Parker-Gray) before installing.

Zoning violations may trigger notices of violation, civil penalties, and required removal or modification of the noncompliant fence. Historic district installations without Board of Architectural Review approval can carry additional penalties.
