Off-Street Parking Standards for the IR: Industrial / Research District

In the City of Dallas IR: Industrial / Research District, residential main uses are generally not permitted, which results in no specific off-street parking requirements for residential projects within this classification. For commercial and industrial developments, the City of Dallas often sets the base off-street parking requirement at zero, unless the project is located within a specialized overlay or is situated contiguous to a residential district containing single-family uses.
