On designated streets, as shown on Map 2 (Ground Floor Use and Transparency and Curb Cut Restrictions) in Appendix A of this Chapter, the special ground floor use, frontage and major building entrance regulations of this Section shall apply to any building or other structure fronting on such streets.

Uses within stories on the ground floor or with a floor level within five feet of the level of the adjoining sidewalk, shall be limited to community facility uses without sleeping accommodations, as listed in Section 115-15 (Modification of Use Regulations in M1-4 Districts), and uses listed in Use Groups 5, 6A, 6B, 6C, 6D, 7A, 7B, 8A, 8B, 8D, 9, 10, 11, 12A, 12B and 12C. A building’s street frontage shall be allocated exclusively to such uses, except for Type 2 lobby space, entryways or entrances to subway stations provided in accordance with Section 37-33 (Maximum Width of Certain Uses). Such non-residential uses shall comply with the minimum depth provisions of Section 37-32 (Ground Floor Depth Requirements for Certain Uses).

For buildings developed or enlarged after September 10, 2007, where the ground floor of such development or enlarged portion of the building fronts upon such designated street, such development or enlargement shall provide a major building entrance onto such street. However, developments or enlargements on zoning lots with frontage on more than one designated street, may provide a major building entrance on only one designated street.
