Regulations governing lot area and lot width; front, side and rear yards; building coverage and building height are as specified in Schedule A.[1] The regulations appearing in Schedule A are hereby made a part of this chapter and subject to the supplementary regulations set forth following:
A.
Lots of less than required dimension.
(1)
Any lot with an area or width less than that required in the district in which said lot is located may be used for any purpose permitted in the district, provided that all other regulations prescribed for the district shall be complied with, and further provided that said lot was held under separate ownership on the effective date of this chapter or any amendment thereto and the owner thereof owned no adjoining unimproved land that could be combined with said lot to meet the dimension requirements.
(2)
In the event that compliance with the yard requirements of the district would result in a residential structure of less width than 24 feet, the Board of Appeals shall determine and fix yard requirements for said lot to permit its reasonable utilization for a permitted use.
B.
Reduction of lot area. The minimum yards and open spaces required by this chapter for any building existing on the effective day of this chapter or for any building hereafter erected or extended shall not be encroached upon or considered as yard or open space for any other building, nor shall any lot be reduced below the district requirements of this chapter.
C.
Corner lots. On a corner lot in any district where a front yard is required, a yard shall be provided on each street equal in depth to the required front yard for the district. One rear yard shall be provided on each corner lot, and the owner shall designate the rear yard on his application for a permit.
D.
Visibility at street corners. On a corner lot in any district where a front yard is required, no fence, wall, hedge or other structure or planting more than three feet in height shall be erected, placed or maintained so as to obstruct visibility of vehicular traffic within the triangular area formed by the intersecting street right-of-way lines and straight line joining said lines at points 20 feet distance from the point of intersection, measured along said lines.
E.
Front yard exceptions. The front yard of all buildings and structures hereafter constructed within a residential district shall be not less nor required to be more than the average front yard of all lots in the block for a distance of 300 feet on each side of such lot. A vacant lot within the three-hundred-foot distance shall be considered as having the minimum front yard required in the district for the purpose of computing such average front yard.
F.
Transition yard requirements.
(1)
Where two districts abut on the same street and the front yard requirements of one district are less than those of the other district, there shall be provided for buildings hereafter constructed or extended within a distance of 50 feet from the district boundary line in the less restricted district a front yard equal in depth to the average of the required depth in the two districts.
(2)
Where the side or rear yard of a lot in one district abuts a side or rear yard of a lot in a more restricted district, there shall be provided along such abutting line or lines a side or rear yard equal in depth to that required in the more restricted district.
G.
Projecting architectural features, terraces, porches, fire escapes and solar energy equipment. Certain architectural features may project into required yards as follows:
(1)
Cornices, canopies, eaves or other architectural features may project a distance not exceeding four feet into any front or rear yard and 40% into any side yard, to a maximum of four feet.
(2)
Fire escapes may project a distance not exceeding four feet six inches.
(3)
Bay windows, balconies and chimneys may project a distance not exceeding three feet.
(4)
Apparatus needed for the operation of active and passive solar energy systems, including but not limited to overhangs, movable insolating walls and roofs, detached solar collectors, reflectors and piping shall be allowed to project into any required front, side or rear yard as necessary to provide for their effective operation. In addition, such equipment shall not be considered in the determination of lot coverage.
(5)
A paved terrace shall not be considered as part of a building in the determination of yard sizes or lot coverage, provided that such terrace is unroofed and without walls, parapets or other form of enclosure exceeding six feet in height.
(6)
In determining the percentage of building coverage of the size of yards for the purpose of this chapter, enclosed porches or porches open at the side but roofed shall be considered a part of the building.
(7)
Unenclosed entrance steps or stairways providing access to the first story, cellar or basement of a building may extend into any required yard a distance not to exceed six feet.
H.
Walls, fences and hedges. The yard requirements of this chapter shall not prohibit any necessary retaining wall nor any permitted fence, wall or hedge, provided that in any residential district, such fence, wall or hedge shall be no closer to any front lot line than two feet and shall comply with visibility at street corners as provided in this section.
I.
Additional height requirements. The height requirements set forth in Schedule A shall be applied to the following special situations as described below:
(1)
The height limitations of this chapter shall not apply to barns, silos and other farm buildings, belfries, church spires, cupolas, penthouses and domes which are not used for human occupancy nor to chimneys, ventilators, skylights, water tanks, solar energy collectors and equipment used for the mounting or operation of such collectors and necessary mechanical appurtenances usually carried above the roof level, nor to flagpoles, monuments, transmission towers and cables, radio and television antennas or towers and similar structures. Such features, however, shall be erected only to such height as is necessary to accomplish the purpose for which they are intended and to ensure that they do not significantly impair the solar accessibility of buildings or solar collectors on adjacent properties. No advertising devices of any kind whatsoever shall be inscribed upon or attached to that part of any chimney, tower, tank or other structure which extends above the roof limitations.
(2)
On through lots 120 feet or less in depth, the height of a building may be measured from the grade of either street. On through lots more than 120 feet deep, the height regulations and basis of height measurement for the street permitting the greater height shall apply to a depth of not more than 120 feet from that street.
