NOTES TO TABLE 1 - Square feet of land per unit. 2 - Units per acre. 3 - Where garages are buried to the extent that the side area normally covered by garages can be occupied by other uses, each of the preceding square footage requirements shall be reduced by 600 square feet. 4 - Fifty feet of unaltered natural land adjacent to any single-family lot. 5 - Corner lot sideyard setbacks where abutting a street shall be 20 feet. * - See § A11-5(A)(2). ** - Same requirements as Zone 4. | |||||||
(2) Setbacks between multiple dwellings.
(a) The front and rear sides of a multiple dwelling shall have a minimum setback of 50 feet from any side of an adjacent multiple dwelling or a setback equal to the combined height of the adjacent multiple dwellings, whichever is greater, except that in no case shall a setback greater than 75 feet be required. This minimum setback shall be reduced to 40 feet where a horizontal extension of the lines created by the nearest exterior vertical surfaces of adjacent buildings would create an angle of not less than 45 degrees.
(b) Minimum setbacks between adjacent multiple dwellings on sides which are not a front or rear side of either building shall be 20 feet or a distance equal to one-half of the combined height of the adjacent buildings, whichever is greater, except that in no case shall a setback be greater than 50 feet be required. This minimum setback shall be reduced to 25 feet where a horizontal extension of the lines created by the nearest exterior vertical surfaces of adjacent buildings would create an angle of not less than 45 degrees.
(3) Maximum impervious surface, see § 155.350.
(4) Screening, see § 155.348.
(5) Landscaping, see § 155.349.
(7) Architecture and building design, see § 155.346. In addition, all commercial buildings constructed in Subzone 5 shall be designed with a residential character and shall have pitched roofs.
(B) The following requirements are in addition to those in division (A). Where there may be a conflict, the requirements herein shall prevail:
(1) Front setbacks prevailing. Where adjoining structures existing at the time of adoption of this article have a greater setback than that required by this article, the front setback of a new structure shall conform to the prevailing setback in the immediate vicinity. The Building Official shall determine the necessary front yard setback in such cases. In no case shall a building be required to be set back more than 50 feet.
(2) Side and rear setbacks, party walls. Buildings may be excluded from side and rear setback requirements if party walls are used and if the adjacent buildings are constructed as an integral structure. This shall not permit structures closer to single-family detached lots, however, than required under subsection (1) above.
