   (A)   See also site design standards in §§ 153.455 through 153.491, for land uses requiring special approval.

   (B)   For height exceptions see § 153.055. There must also be compliance with the Tri-City Area Joint Airport Zoning Ordinance, effective June 11, 1970, which requires a special permit to erect or extend a structure, including buildings, radio and television antennas, chimneys, stacks, gables, towers, or other additions attached to structures in excess of 99 feet above the existing ground level.

   (C)   (1)   In any R-1, R-1A, or R-2 District, the width of the required minimum street side yard on any corner lot shall be three-fourths of the minimum front yard depth required on the contiguous interior residential lot fronting on the same street as the side yard abuts. If the front yard on such interior lot is greater than the minimum required, then the minimum street side yard required shall be three-fourths of the front yard depth as determined in § 153.062(A)(1). A minimum of 12 feet shall be required where there is no interior lot. In any R-3, R-4, RO-1, or B-1 District, the width of minimum required street side yard on corner lots shall be ten feet.

      (2)   Where the side wall of a single- or two-family dwelling exceeds 35 feet in length, the side yard adjacent to such wall shall be increased, in addition to the other requirements contained herein, one foot for each five feet of such excess length up to a maximum side yard width of 50 feet. For the purpose of this section, the length of a side wall of a building shall be the shortest distance between the front yard and the rear yard.

      (3)   In all residential districts on a lot occupied by any building which is permitted in said districts other than solely for residential purposes, the width of each yard shall be computed as follows:

      Minimum side yard width =

   Length of bldg. (in ft.) along side yd. + 2 x ht. of bldg. (in ft.)

                  6

   (D)   In all residential, business, and industrial districts, the required front and street side yard setbacks shall not be used for off-street parking, loading, or unloading, and shall remain as open space unoccupied and unobstructed from the ground upward except for landscaping, plant materials, or vehicle access drives, and except that for single-family detached residences and two-family houses, one passenger motor vehicle may be parked on a paved driveway or garage apron in a required front yard. (See also §§ 153.062 and 153.063.)

   (E)   The minimum floor area per dwelling unit shall not include areas of basements, breezeways, unenclosed porches, terraces, attached garages, attached sheds, or utility rooms.

   (F)   Applies only to multiple dwellings, boarding houses, tourist homes, rooming houses, and similar residential units.

   (G)   For two-family residences, a minimum lot width of 60 feet and a minimum lot area of 7,200 square feet shall be provided. For new or conversion of existing structures to contain three or four dwelling units, the minimum required lot area shall be 7,200 square feet plus 1,000 square feet per dwelling unit in excess of two units.

   (H)   For all dwellings there shall be provided a minimum lot area of 4,000 square feet for the first dwelling unit in a building plus 1,200 square feet for each additional dwelling unit therein. Each lot occupied by any other building providing permanent or transient sleeping accommodations shall contain at least 4,000 square feet for the first family or group of five occupant accommodations, with at least 1,200 square feet for each additional group of five occupant accommodations or major fraction thereof.

   (I)   (1)   Minimum side yards for multiple dwellings, boarding houses, tourist homes, rooming houses, and similar residential units shall be computed as follows:

      Minimum side yard width =

   Length of bldg. (in ft.) along side yd. + 2 x ht. of bldg. (in ft.)

                  15

      (2)   Where two or more multiple, row, or terrace dwellings are erected upon the same lot, a minimum yard space of 50 feet in width shall be provided between structures. This yard width shall be increased by two feet for each ten feet or part thereof by which each multiple, row, or terrace dwelling structure, having common yards, exceeds 40 feet in length on that side of the dwelling structure facing the common yard; and also increased by one foot for each five feet or part thereof by which each permitted multiple dwelling structure having common yards exceeds 40 feet in height on that side of the dwelling structure facing the common yard.

   (J)   Lot area requirements for residential buildings are determined from FAR and RSR standards, yard space, and off-street parking requirements.

   (K)   (1)   Floor space area per dwelling unit (sq. ft.) shall be as follows:

 

	Minimum Size (sq. ft.)
Efficiency	450
One-bedroom unit	525
Two-bedroom unit	750
Three-bedroom unit	850
Four- or more bedroom unit	1,000

 

      (2)   Not more than 5% of dwelling units in any building may be of efficiency type. The term bedroom excludes kitchens, bathrooms, utility rooms, libraries, dens, and rooms for common use of dwelling unit occupants.

   (L)   Where an existing front setback line has been established by existing commercial buildings occupying 50% or more of the frontage within the same block, such established setback shall apply.

   (M)   For nonresidential buildings, side yards are not required along interior side lot lines if all walls abutting or facing such lot lines are of fire-resistive construction as provided for in the Building Code. However, where a commercial district borders on a side street and a residential district exists in the same block, there shall be provided a setback of ten feet for all buildings, parking, and loading area. Where any or all of a building in a B-1, B-1A, or B-2 District is used for residential purposes, side yards shall be provided as required in the R-4 District.

   (N)   Refer to §§ 153.057, 153.058, 153.061, and 153.062.

   (O)   Minimum yard dimensions for M-1, M-2, and M-3 Districts are as follows: any lot adjacent to or across a street from an R District shall provide the same abutting front, side, or rear yard as is required in the R District adjacent to or across said street.

   (P)   Minimum yard dimensions for M-2 and M-3 Districts are as follows: any lot adjacent to or across a street from an R District shall provide twice the amount of abutting front, side, or rear yard as is required in the R District adjacent to or across said street.
