For the purpose of determining permitted #surface area# of #signs# for #zoning lots# occupied by more than one establishment, any portion of such #zoning lot# occupied by a #building# or part of a #building# accommodating one or more establishments on the ground floor may be considered as a separate #zoning lot#. No #illuminated sign# shall have a degree or method of illumination that exceeds standards established by the Department of Buildings by rule pursuant to the City Administrative Procedure Act. Such standards shall ensure that illumination on any #illuminated sign# does not project or reflect on #residences# or #joint living-work quarters for artists# so as to interfere with the reasonable use and enjoyment thereof. Nothing herein shall be construed to authorize a #sign with indirect illumination# to arrange an external artificial source of illumination so that direct rays of light are projected from such artificial source into #residences# or #joint living-work quarters for artists#.
