Any change of lot line, except where only the dimensions of
two existing lots are changed and additional building lots are not
created, shall be considered to be a subdivision and shall be subject
to Planning Board review and approval. A plat indicating such change
shall be filed with the office of the Westchester County Clerk prior
to such change taking effect. A copy of the filed plat shall also
be submitted to the City Assessor. No building permit shall be issued
for the use or development of any lot which has not been so created
subsequent to the effective date of this chapter.
A. Lot for every building. Every building hereafter erected shall be
located on a lot and there shall be no more than one principal building
and its accessory buildings on one lot, except for multifamily and
nonresidential buildings in districts where such uses are permitted.
B. Subdivision of a lot. Where a lot is formed hereafter from part of
a lot already occupied by a building, such separation shall be effected
in a manner which will not impair conformity with any of the requirements
of this chapter with respect to the existing building and all yards
and other required spaces in connection therewith. No permit shall
be issued for the erection of a building on the new lot thus created
unless it complies with all the provisions of this chapter.
C. Irregularly shaped lots. Where a question exists as to the proper
application of any of the requirements of this chapter to a particular
lot because of its peculiar or irregular shape, the Zoning Board of
Appeals shall determine how the requirements of this chapter apply.
D. New building on lots smaller than required. A permit may be issued
for the erection of a building for a permitted use on a lot for which
a valid conveyance has been recorded prior to July 1, 1963, notwithstanding
that the area or dimensions of such lot are less than that required
for the district in which such lot is located, provided that:
(1) The lot met the zoning requirements at the time the deed to the lot
was created.
(2) All yard setbacks and other building related requirements which are
in effect at the time of the obtaining of the building permit are
complied with; provided, however, that in a one- or two-family residence
district, the required side and rear yard setbacks may be reduced
in proportion to the dimensional nonconformity of the lot to allow
for the construction of a one- or two-family dwelling.
(3) The ownership of such lot was not the same as any other lot or lots
contiguous thereto on July 1, 1963. If that is not the case, such
other lot or lots, or so much thereof as may be necessary, shall be
combined with the first-named lot to make one or more conforming lots,
whereupon a permit may be issued, but only for such combined lots.
Where the required area or dimensions of lots are changed by an amendment
to this chapter, any lot legally in existence on that date and made
nonconforming by such amendment may be built upon as provided in this
section.
E. Minimum distance between buildings on the same lot.
(1) Minimum distance between principal buildings in residence districts.
In all residence districts, the minimum distance between principal
buildings shall equal at least the average height of such buildings
at the points where such buildings are closest to one another.
