Off-Street Parking Standards for the LO-1 Limited Office District 1
In the City of Dallas, the LO-1: Limited Office District 1 generally requires no off-street parking for residential uses like college dormitories and most office or retail uses. However, a significant mandate for the LO-1 District is that all required off-street parking must be provided at or below ground level [Section 51A-4.121(b)(5)]. For certain specific commercial uses such as catering services or larger restaurants, parking ratios are applied based on the total floor area [Section 51A-4.202(3)].
