In addition to complying with the provisions of the district in which a use is permitted, each use shall comply with the following standards and requirements where applicable. For certain specific uses or exceptional situations, these basic regulations are supplemented by Article XIII and by other provisions of this chapter.
A.
Lot area and yard requirements. The lot or yard requirements for any new building or use shall not include any part of a lot that is required by any other building or use to comply with the requirements of this chapter. No required lot area or yard shall include any property, the ownership of which has been transferred subsequent to the effective date of this chapter, if such property was part of the area required for compliance with the dimensional requirements applicable to the lot from which such transfer was made.
B.
Minimum lot area. Where a minimum lot area is specified, no principal building or use shall be erected or established on any lot of lesser size than as specified within this chapter.
C.
Minimum lot width.
(1)
Where a minimum lot width is specified in the applicable district regulations or other regulations of this chapter, no principal building or use shall be erected or established on any part of a lot which has a width less than is specified.
(2)
The lot width for a single-family semidetached dwelling or end unit of townhouses shall be measured from the side lot lines to the center line of the wall in common with an adjoining dwelling.
D.
Yard requirements. No portion of a building or structure shall be built within the minimum depth of front, side, or rear yards as specified within this chapter.
E.
Maximum height of buildings. No building shall exceed the maximum height of buildings specified in this chapter.
F.
Permitted variations from required areas. The minimum lot, yard and height requirements of Articles V through XII shall prevail in all cases, except as follows:
(1)
Existing nonconforming lots. In any district where a nonconforming lot exists as a separate entity at the time of passage of this chapter and where the owner of the nonconforming lot does not own an adjoining lot, then the following development is permitted:
(a)
Lots in the R-1 and R-2 Zoning Districts.
[1]
If the lot is located in the R-1 or R-2 District, a single-family dwelling, including any attached permitted accessory use, may be constructed on it as a permitted use subject to the following requirements:
[2]
If the lot has an existing single-family dwelling located on it, then the dwelling may be enlarged to comply with, but not exceed, the requirements listed above.
[3]
Accessory structures located in the rear yard area which are not attached to the principal structure may be built up to eight feet from the rear lot line and up to two feet from one side lot line, provided that such accessory structures are not located closer than four feet to the other side lot line and are not less than 10 feet from any principal structure.
(b)
Lots in nonresidential zoning districts (H-1, TC, C-1, C-2 and I-1). If the existing nonconforming lot is located in any remaining nonresidential zoning district (H-1, TC, C-1, C-2, I-1), then a structure not exceeding two stories in height may be constructed on it, for a use permitted in the district in which it is located, provided that the off-street parking and loading requirements of this chapter shall be complied with and that the front, side and rear yards, as required by the district in which the use is located, are not reduced by more than 1/3 of said requirement and are compatible with the surrounding area, as determined by the Board. Said use shall be considered to be a special exception subject to the review and approval of the Board.
(2)
Height limitations. District height limitations for church spires, cupolas and domes, monuments, water towers, chimneys, smokestacks, antennas, farm structures, silos and flag poles may extend to a maximum height of 150 feet. Required utility and radio and television station transmitting or receiving towers which are permitted under the requirements of this chapter may exceed the district height limitations by 35 feet. Although exempted from structural height limitations, these structures should not impair solar access of buildings or solar collector locations.
(3)
Front yard exception. When an unimproved lot is situated between two improved lots, each having a principal building within 25 feet of the side lot line of the unimproved lot, and where the lot is not located on a major state or federal highway, then the required front yard may be reduced to a depth equal to that of the greater front yard of the two adjoining lots; provided, however, that it may not be reduced to below 15 feet in Residential Districts R-1 and R-2.
(4)
Projections into yards. Projections into required yards may be permitted as follows, except that no such projection shall be located closer than three feet to any side lot line or 10 feet to any rear lot line or 15 feet to any front lot line, except as may be provided for in § 170-92 for existing nonconforming lots:
(a)
Fire escapes, uncovered stairs and landings, canopies, eaves or other architectural features not required for structural support may project into the required side, front or rear yard not more than a total of three feet.
(c)
Patios may be located in the required yard area, not closer than the following to any property line, except that patios constructed on existing nonconforming lots may line up with and be as wide as the principal structure on the lot:
(5)
Changes to conforming uses and buildings. Any conforming use or building may be repaired, maintained, restored or rebuilt up to the same dimensions existing at the time of the effective date of adoption of this chapter.
(6)
Any enlargement of an existing conforming use or structure on the same lot must comply in all respects with the regulations of this chapter.
