The least dimensions of any inner court at its
lowest level shall not be less than four feet. The minimum area of
an inner court shall not be less than twice the square of its required
least dimensions.
No existing building shall be altered, enlarged
or rebuilt except in conformity with the regulations herein prescribed.
Unless otherwise expressly provided, the terms "rear yard," "front
yard," "side yard," "inner court" and "outer court" when used in this
chapter shall be deemed to refer only to a rear yard, front yard,
side yard, inner court or outer court as required by this chapter.
No lot on which a building is or shall be erected shall be reduced
or diminished so that the yards, courts or other open spaces shall
be smaller than as prescribed by this chapter.
Every room in which persons live, sleep, work
or congregate shall have at least one window or ventilating skylight
opening directly either upon a street or upon a rear yard, front yard,
inner court or outer court located upon the same lot and conforming
to the requirements prescribed by this chapter as to the minimum area
and least dimensions. The windows or skylights opening upon such required
street, rear yard, front yard, inner or outer court shall have a minimum
area in each room equal to at least 1/8 of the floor area of such
room. Courts, yards or other open spaces, if provided in addition
to those provided by these regulations, need not be of the area and
dimensions herein prescribed. No court, yard or other open space provided
about any building for the purpose of complying with the provisions
of this chapter shall again be used as a yard, court or other open
space for any other buildings.
Dwellings in business zones shall be erected
in conformity with the requirements of the B Residence Zone; where
the first story is devoted entirely to nonresidential use, no side
yard shall be required on the first story and the building area, rear
yard and court requirements may begin at the second-story sill level
or 15 feet above the curb.
No building to be used as a dwelling shall be
constructed or altered in the rear of a building situated on the same
lot. Nothing contained herein, however, shall be construed to prohibit
the construction of more than one building on a lot as garden apartments
if the construction of the said garden apartments otherwise complies
with the requirements of this chapter.
An interior lot running through the block from
street to street or to within 55 feet of its rear shall be required
to provide a rear yard when improved with a single building.
Accessory buildings may occupy 40% of the required
rear yard to an average height of 15 feet above the ground level in
a residence zone. The yard area occupied by such accessory building
shall, however, be included in computing the maximum percentage of
the lot area which may be built upon in any given case.
The area required in a court or yard at any
given level shall be open from such level to the sky, unobstructed
except for the ordinary projections of skylight and parapets above
the bottom of such courts or yards, and except for the ordinary projections
of windowsills, belt courses, cornices and other ornamental features
to the extent of not more than 12 inches.
Any plot existing as a separate parcel and not
complying with minimum area or width of lot requirement in the schedule
at the time of the passage of this chapter may, notwithstanding such
fact, upon approval by the Planning Board, be improved with a building
in accordance with the other regulations of its residence zone, provided
the owner owns no adjacent land which may, without undue hardship
to him, be included as a part of the plot in question.
