The MO-2 Mid-Range Office District in Dallas
The MO-2 Mid-Range Office District in the Municipality of Dallas is a high-intensity professional zone characterized by a maximum floor area ratio of 3.0 and a height limit of 160 feet or 12 stories. This district is designed to accommodate sophisticated office and medical developments alongside limited retail and service uses that support both building occupants and the broader community [Section 51A-4.121(c)].
Purpose and General Character
The MO-2 district represents a specific category of the Dallas office regulations intended for mid-range intensity. The primary purpose of the MO-2 district is to provide a location for office and limited service uses that serve community and city-wide needs [Section 51A-4.121(c)(1)].
In the Municipality of Dallas, MO-2 districts are strategically placed adjacent to higher-density residential areas or near low and medium-density office, retail, commercial, and light industrial zones. To ensure the functionality of these professional hubs, the Dallas Development Code allows certain complementary retail uses to satisfy the daily needs of office patrons and nearby residents [Section 51A-4.121(c)(1)].
