Amendment relating to
porch height,
with 25-foot-flat limit
(Table 7-6)
3-5-07
Amend Note 1.2 of Table 7-6 as follows:
Note 1.2. Porch In Front Yard. On a building site in a residential district with a front yard depth
of 20 feet or more, a porch may project up to 120 inches into the front yard if it meets all of the
following criteria:
(i) It is neither designed nor usable for motor vehicles;
(ii) The volume of the projecting part of the porch does not exceed 50 cubic feet per
foot of front street line (Example: the maximum projecting volume on a 521/2-foot
wide site would be 50 cubic feet x 52.5, or 2,625 cubic feet).
(iii) The porch's outside perimeter is open and unobstructed, except for the following
features: (a) Ordinary window screens. (b) A solid or partially open safety rail not
higher than 3.5 feet above the porch floor. (c) Supporting vertical columns, if the
total width of the outer faces of the columns does not exceed either 50% of the
outside perimeter of the porch or 25% of the theoretical outside perimeter of a
maximum-sized porch. The width of a column is measured at its thickest point
above 3.5 feet above the porch floor.° The "maximum-sized porch" is 120 inches
deep and extends from one side yard line to the other, but it is limited by the open
area requirement for the front yard. The "outside perimeter" of a porch is the
portion of the perimeter out in the front yard; it does not include the portion of the
perimeter adjacent to a building or lying along the front setback line.
iv At no point in the front yard does the porch have a height greater than 25 feet €4o

Amendment relating to
buildings in rear yard
(Table 7-6)

Amend Note 3 of Table 7-6 as follows:
Note 3. Buildings In Rear Yard or SF Bziffervard. _A building may be
located in a rear yard or SF Bufferyard if it meets all of the following criteria: (a)
No part of it-the building may be closer than five feet to the rear property line (or
to any SF District, if in a SF Bufferyard). (b) The minimum horizontal
separations between the building and all other buildings on the building site (other
than those located completely within the rear yard or SF Bufferyard) are 7% of
the building site depth (measured from main wall to main wall) and 5% of the
building site depth (measured between the closest parts of the buildings), except
for transitional structures specifically allowed below. Example: If the depth is
100 feet, the minimum separations are seven and five feet respectively. (b* (c)
Within ten feet of another building site in an SF District (whether on the side, rear
or otherwise), 4- the building may have no window, door or other opening above
the ground floor (and facing the property line of the other building site), except
for epaEltte-translucent (but not transparent), non-operable openings or skylights.
} Space in the fffp
building may only be used for single-family
(detached) use. (e) The building may not be a principal buildine. unless there
is a transitional structure between the main part of the principal building and the
part in the rear yard (or SF Bufferyard) A transitional structure may be an
arcade, a "bridge," a .porch or other building space but no part of the structure
may have a height greater than the horizontal distance from that part to the nearest
property line. 4 "
