The regulations set forth in this article qualify or supplement
the district regulations appearing elsewhere in this chapter.
Where more than 25% of the total floor area of any structure
in a commercial district other than the C-3 District is used for dwelling
purposes, in a structure which may also contain nonresidential uses,
the minimum height, area and bulk requirements for residential development
applicable in the district in which such structure is located shall
apply, subject to the side yard modification for mixed uses contained
elsewhere in this article. Where 25% or less of the total floor area
of such structure is used for dwelling purposes, the structure shall
be subject to the height, area and bulk requirements applicable to
nonresidential structures in the district.
Where single-family detached dwellings have a minimum lot area
requirement of 10,500 square feet, individual lot area may be reduced
to 9,000 square feet so long as the overall average lot size in the
subdivision is 10,500 square feet.
For example,
|
10 lots at 9,000 square feet each
|
10 lots at 12,000 square feet each
|
---------------------------------------------------
|
20 lots at 210,000 square feet = 10,500 square foot average
lot size
|
Open or lattice-enclosed fire escapes, outside stairways and
balconies opening upon fire towers and the ordinary projections of
chimneys and flues may project into the required rear yard for a distance
of not more than five feet, but only where the same are so placed
as not to obstruct light and ventilation.
No sign, fence wall, hedge, planting or other obstruction to
vision, extending to a height in excess of three feet above the established
street grade, shall be erected, planted or maintained within the area
of a corner lot that is included between the lines of the intersecting
streets and a straight line connecting them at points 20 feet distant
from the intersection of the street lines.
