For the purposes of this Chapter, a change of use is a change to another use listed in the same or any other Use Group. However, a change in ownership or occupancy shall not, by itself, constitute a change of use.

Except as provided in this Section, a non-conforming use may be changed to any conforming use, and the applicable district bulk regulations and accessory off-street parking requirements shall not apply to such change of use or to alterations made in order to accommodate such conforming use, but shall apply to any enlargement.

A non-conforming use may be changed to another non-conforming use only in accordance with the provisions of this Chapter.

Any such change of use permitted by this Chapter shall conform to the applicable district regulations on accessory off-street loading berths as set forth in Section 52-41 (General Provisions) and on accessory signs, except that in Residence Districts such change shall conform to the regulations on accessory signs applicable in a C1 District.

In the Manhattan Core, a non-conforming use may be changed to an automobile rental establishment, public parking garage or public parking lot in Use Groups 8 and 12D only pursuant to the provisions of Article I, Chapter 3, and in the Long Island City area, as defined in Section 16-02 (Definitions), a non-conforming use may be changed to a public parking garage or public parking lot in Use Groups 8 and 12D only pursuant to the provisions of Article I, Chapter 6.
