In districts other than the residential districts,
garbage and rubbish shall be placed out for collection at the outer
edge of the sidewalk only on the days of collection not earlier than
6:00 a.m. and shall not be left out after the collection has been
completed. At all other times in the business districts, it shall
be impermissible to store garbage outside in front of the building,
either on public or on private property, including, but not limited
to, setback areas, alcoves and vestibules. Where a building is located
on a corner, any side of the building that faces a public street shall
be considered the front of the building.
