Zoning Designation: RT-1-2

Jurisdiction: City of San Diego

The purpose of the RT zones is to provide for attached, single-dwelling unit residential development on small lots with alley access. It is intended that these zones provide for more urbanized, single-unit living at densities that are historically more typical of multiple-unit zones. The RT zones provide transition opportunities between single-unit neighborhoods and higher density multiple-unit neighborhoods and in some instances may replace multiple-unit zones at similar densities. The RT zones are intended to be applied on subdivided blocks with alleys that are within or close to highly urbanized areas, transit areas, and redevelopment areas. RT-1-2 requires minimum 3,000-square-foot lots.
