Arlington County RA14-26 Multiple-Family Dwelling District Guide

Jurisdiction: Arlington CountyCode Version: March 14, 2026

The RA14-26 Multiple-family Dwelling District in Arlington County is a high-density residential zone primarily intended for apartment and townhouse development with a standard height limit of 3.5 stories or 35 feet [Section 6.2.3]. Minimum lot areas for multiple-family structures in the RA14-26 district start at 7,500 square feet, and the County Board may grant special exceptions to increase density and height for projects providing low- or moderate-income housing [Section 6.2.3, Section 12.3.7].

Purpose and General Character

The specific purpose statement for the RA14-26 Multiple-family Dwelling District is reserved within the ordinance [Section 6.2.1]. However, the general character of the Arlington County RA14-26 district is established through its density and dimensional requirements, which favor multiple-family buildings and townhouses while allowing for the preservation of existing one-family detached dwellings [Section 6.2.3, Section 12.3.4]. The RA14-26 district serves as a high-density residential classification that permits a transition from lower-density residential zones to more intense commercial or mixed-use areas.
