Setback Requirements for the MC-4 Multiple Commercial District in Dallas
In the Dallas MC-4: Multiple commercial district 4, buildings are required to maintain a minimum front yard setback of 15 feet, with an additional 20-foot urban form setback for portions of a structure exceeding 45 feet in height. Side and rear yard setbacks are not generally required unless the MC-4 property is adjacent to or directly across an alley from a specific residential district, in which case a 20-foot setback must be maintained. Furthermore, structures in this Dallas district that exceed 45 feet in height are subject to "tower spacing" regulations that increase side and rear setbacks on a 1:2 ratio up to a maximum of 30 feet.
Front Yard Setbacks in Dallas MC-4
The Dallas Development Code establishes both a base setback and an "urban form" setback for the front yard of any property zoned as an MC-4: Multiple commercial district 4 [Section 51A-4.126(f)(4)(A)].
- Minimum Front Yard: All structures must be set back at least 15 feet from the front property line.
- Urban Form Setback: To prevent a "canyon effect" on the street, any portion of a building in the Dallas MC-4 district that rises above 45 feet in height must provide an additional 20-foot setback from the front yard line.
Side and Rear Yard Setbacks in Dallas MC-4
Setback requirements for side and rear yards in the Dallas MC-4: Multiple commercial district 4 are primarily determined by the zoning of the adjacent properties [Section 51A-4.126(f)(4)(B)].
- Residential Adjacency: A minimum 20-foot side and rear yard setback is mandatory if the MC-4 lot is adjacent to or directly across an alley from any of the following Dallas residential districts: R, R(A), D, D(A), TH, TH(A), CH, MF, or MF(A).
- General Rule: In all cases where the residential adjacency criteria above are not met, the Dallas MC-4 district has no minimum required side or rear yard setback.
- Tower Spacing: For buildings taller than 45 feet, an additional side and rear yard setback is required at a rate of one foot for every two feet of height above the 45-foot mark. This cumulative setback does not need to exceed 30 feet in total.

Additional Placement Considerations
While these setbacks define the buildable area, the Dallas Development Code also specifies that in an MC-4: Multiple commercial district 4, aboveground parking structures must be included in lot coverage calculations, whereas surface parking lots and underground structures are excluded from those specific limits [Section 51A-4.126(f)(4)(F)].
