Arlington, Virginia Subdivision & Lot Size Rules
Arlington, Virginia regulates subdivision standards and lot-size requirements through county land-use rules and the Arlington County Code [1]. This guide explains how subdivisions are reviewed, typical lot and frontage considerations, application steps, enforcement pathways, and where to find official forms and contacts. Requirements vary by zoning district and project type; site-specific standards, minimum lot sizes, setbacks, and lot coverage limits depend on the zoning ordinance and subdivision plat approvals.
