1211.19 YARDS FOR MULTI-FAMILY DWELLINGS.
(a)   Arrangement and Intent. The yards of multi-family buildings shall be related to the plan of the dwelling units within the building as well as to yard requirements. Buildings shall be arranged so as to assure privacy between adjacent buildings and intersecting wings of buildings, from streets, parking spaces and recreation areas. In order to encourage more attractive arrangements of buildings and greater utilization of yards and the above objectives, regulations are established as described below.
(b)   Minimum Distance From Buildings to Side or Rear Lot Lines. A minimum distance between any multi-family dwelling or parts thereof in a development area and any side or rear line of such development area shall vary according to the length and height of the building. Such minimum distance shall be determined by the following formulas:
Where land in R-MF-40, R-MF-24 and R-MF-15 Districts abuts R-1F-80 or R-2F-100 Districts, the minimum distance between building and side or rear property line shall not be less than the greater of fifty feet or the following formula:
Minimum Distance = A+L + H
F
Where land zoned as R-MF-40, R-MF-24 and R-MF-15 abuts all other zoning districts;
Minimum Distance = A+L + H
F
2

the elements of such formula being described as follows:
A =   20 feet where the (L) is less than 50 feet and the (H) is less than 30 feet. In all other cases "A" shall be 50 feet.
L =   length of the property line in feet measured between perpendicular lines to the property line where such perpendicular touch the extreme ends of the building.
H =   height of building in feet.
F = division factor from the schedules below.
Buildings whose length (L) is up to 100 feet and:
the height (H) is up to 50 feet            F = 5
the height (H) is 50.1 to 100 feet            F = 3
Buildings whose length (L) is from 100.1 feet to 250 feet and:
the height (H) is up to 50 feet            F = 3.5
the height (H) is from 50.1 to 100 feet         F = 2.5
Buildings whose length (L) is 250 feet or more and:
the height (H) is up to 50 feet            F = 2.5
the height (H) is from 50.1 to 100 feet         F = 1.5
When computing the setback formula for buildings of more than one wing, all wings that are not within fifteen degrees of being perpendicular to the property line shall be considered as a separate building for measurement purposes.
All attached wings that are within fifteen degrees of the perpendicular to the property line shall be considered as one continuous building and the entire length between perpendicular lines to the property line shall be used for determining the length requirement of the formula.
The required setback shall be measured from the wall plane or point that is the closest to the property line.
In no case shall the minimum distance between the building and the side or rear property line be less than twenty-five feet in R-MF-40 and R-MF-24 Districts and not less than fifty feet in R-MF-15 Districts.
(c)   Minimum Distances Between Buildings. The minimum distance between multi- family buildings or between opposite building walls of the same building shall vary according to length and height of the buildings. Such minimum distances shall be determined by the following formula:
MD = LA + LB + n (HA + HB)
F
provided that, in no case shall the minimum distance be less than twenty feet.
The elements of this formula are as follows:
MD =the minimum required horizontal distance between any wall of one building and another wall of that building and/or wall of another building.
LA =   the total length of building "A", which shall be the length of the portion or portions of any wall or walls of building "A" from which lines drawn perpendicular will intersect any wall of building "B" or another wall of building "B".
LB =   the total length of building "B" or of another wall of building "A" which shall be the length of the portion or portions of any wall or walls of building "B" or another wall of building "A", from which lines drawn perpendicular will intersect any wall of building "A".
HA =   the height of building "A".
HB =   the height of building "B" or of the other wall of building "A".
n =   a factor which is equal to two for R-MF-40 and R-MF-24 Districts and one for a R-MF- 15 District.
F =   a factor which is equal to five for a R-MF-40 and R-MF-24 District and three for a R- MF-15 District.
