Specific Setback Conditions and Interpretations

Front Yard Requirements

In the LO-1: Limited Office District 1, the 15-foot front yard setback must be open and unobstructed, though certain ordinary projections like window sills, belt courses, and cornices may project up to 12 inches into the required yard [Section 51A-4.401].

Residential Adjacency for Side and Rear Yards

The 20-foot side and rear yard requirements in the City of Dallas apply only when the LO-1: Limited Office District 1 lot is situated:

Contiguous to a residential district.
Directly across an alley from a residential district.

For the purposes of this regulation, residential districts include R, R(A), D, D(A), TH, TH(A), CH, MF, or MF(A) districts [Section 51A-4.121(b)(4)(B)]. If the property is not adjacent to or across an alley from these specific districts, the Dallas Development Code does not require a minimum side or rear yard.

Additional Setback Factors

Urban Form Setback: For any portion of a structure that exceeds 45 feet in height, the City of Dallas requires an additional 20-foot front yard setback [Section 51A-4.121(b)(4)(A)(ii)].
Mechanical Equipment: A hedge or low wall at least 30 inches in height must be provided to screen the edge of vehicular use areas or parking structures within the parking setback area [Section 51A-13.601].
