SKY EXPOSURE PLANE
(23-631a, 24-521)
- In the districts indicated, the height and setback of a
#building or other structure# shall be as set forth herein
except where modified pursuant to paragraphs (h) and (j) of
this Section.
For the purposes of this Section, where #base planes# of different elevations apply to different portions of a #building or other structure#, each such portion of the #building# may be considered to be a separate #building#. Furthermore, for the purposes of this Section, #building segments# may be considered to be separate #buildings# and #abutting semi-detached buildings# may be considered to be one #building#.
The perimeter walls of a #building or other structure# are those portions of the outermost walls enclosing the #floor area# within a #building or other structure# at any level and height is measured from the #base plane#. Perimeter walls are subject to setback regulations at a maximum height above the #base plane# of:
21 feet R2A R2X R3 R4A 25 feet R1-2A R4-1 R4 R5A 26 feet* R3 R4-1 R4A within #lower density
growth management areas#
* In R3, R4-1 and R4A Districts within #lower density growth management areas#, where a #base plane# is established at a #base flood elevation# higher than grade, the maximum perimeter wall height shall be 21 feet above such #base flood elevation# or 26 feet above grade, whichever is more
Above these heights, sloping planes control the maximum height of the #building or other structure# requiring either a setback or a pitched roof. These planes start at the maximum permitted height of the perimeter walls and meet at a ridge line of 35 feet above the #base plane#. The exact locations of these planes are flexible and are determined in the steps set forth in paragraphs (b)(1) through (b)(5), as follows:
- At a height of 35 feet above and parallel to the #base
plane#, a plane is projected above the area enclosed by
and including the perimeter walls of the #building or
other structure#. A second plane (the perimeter wall
plane) is projected in the same manner at a height of 21
or 25 feet above the #base
plane#. (See Figure A)
Figure A
(23-631b1) - Each perimeter wall of the #building or other structure#
with a horizontal dimension of eight feet or more which
projects from an adjacent perimeter wall at least 18
inches may have an apex point directly above it on the 35
foot high plane. (See Figure B). The location of the apex
point is flexible provided it is directly above its
perimeter wall and provided a line drawn from the
intersection of two perimeter walls to such an apex point
does not exceed 80 degrees to the horizontal. An apex
point is not required for each qualifying perimeter wall;
however, the maximum number of apex points above each such
wall is one.
Figure B
(23-631b2) - One "ridge line" is extended in a straight line from each
apex point along the 35 foot high plane. Ridge lines which
connect two apex points may cross other ridge lines.
Otherwise, ridge lines which extend from only one apex
point must terminate at a point of intersection with
another ridge line. (See Figure C)
Figure C
(23-631b3) - Sloping planes are extended in a straight line outward and
downward from each ridge line until they intersect the
perimeter wall plane. Every sloping plane generated must
intersect the perimeter wall plane for the full width of
the ridge line from which it extends. (See Figure D). The
maximum angle of pitch for any sloping plane may not
exceed 80 degrees to the horizontal. Sloping planes
extended from ridge lines perpendicular or within 45
degrees of being perpendicular to each other may
intersect, in which case the higher plane defines the
limit of the envelope. Sloping planes extended from ridge
lines parallel or within 45 degrees of being parallel to
each other must intersect the perimeter wall plane without
intersecting each other.
Figure D
(23-631b4) - The perimeter walls are then extended vertically beyond
the perimeter wall plane, up to the heights defined by the
sloping planes generated in paragraph (4). (See Figure E).
The perimeter walls of the #building or other structure#,
the sloping planes and the perimeter wall extensions
define the #building# envelope. (See Figure F). Those
items listed in Section 23-44 (Permitted Obstructions in
Required Yards or Rear Yard Equivalents), and roofed
porches and porticoes subject to all applicable
provisions, may penetrate the #building# envelope below
the maximum permitted perimeter wall height. Eaves may
extend the roof lines 18 inches beyond the exterior walls.
(23-631b5.1) Figure E and F
(23-631b5.2) - Special Situations
- For convex curved perimeter walls, the #building or
other structure# must be within a plane curve
tapering uniformly to a vertex located at a height of
35 feet. For concave curved perimeter walls, the
#building or other structure# must lie within a plane
curve extending from the maximum perimeter wall
height to a ridge line parallel to the prolongation
of the perimeter wall at the 35 foot level. Such
plane curves may not exceed a pitch of 80 degrees in
relation to a plane drawn parallel to the #base
plane# at the maximum height of the permitted
perimeter wall. (See Figure G).
Figure G
(23-631b6.i) - In R2X Districts, at the 21 foot maximum permitted height
of a perimeter wall, sloping planes are projected inwards
and upwards. From a permitted front perimeter wall and
from 21 feet above the #base plane# and 20 feet from and
parallel to a #rear lot line#, such sloping plane shall
not exceed a pitch of 45 degrees in relation to a plane
drawn parallel to the #base plane# at a height of 21 feet.
(See Figure H). Other sloping planes slope toward a ridge
line at 35 feet and may not exceed a pitch of 80 degrees
in relation to a plane drawn parallel to the #base plane#
at a height of 21 feet.
Figure H
(23-631b6.ii)
- For convex curved perimeter walls, the #building or
other structure# must be within a plane curve
tapering uniformly to a vertex located at a height of
35 feet. For concave curved perimeter walls, the
#building or other structure# must lie within a plane
curve extending from the maximum perimeter wall
height to a ridge line parallel to the prolongation
of the perimeter wall at the 35 foot level. Such
plane curves may not exceed a pitch of 80 degrees in
relation to a plane drawn parallel to the #base
plane# at the maximum height of the permitted
perimeter wall. (See Figure G).
- At a height of 35 feet above and parallel to the #base
plane#, a plane is projected above the area enclosed by
and including the perimeter walls of the #building or
other structure#. A second plane (the perimeter wall
plane) is projected in the same manner at a height of 21
or 25 feet above the #base
plane#. (See Figure A)
- In the district indicated, no portion of the #building or other structure#, including the apex of a roof, shall penetrate a plane 24 feet in height above the #base plane#.
- In the district indicated, except R5A, R5B and R5D Districts, no portion of a #building or other structure#, including the apex of a roof, may penetrate a plane 40 feet above the #base plane#. In addition, the maximum height of a #street wall# above the #base plane# shall be 30 feet. Above such height, a setback of 15 feet is required. Within the setback distance, no portion of the #building or other structure#, including the apex of a roof, may penetrate a plane rising from the maximum #street wall# height, at 20 degrees to the horizontal. On #corner lots#, the 30 foot maximum #street wall# height shall apply to only one #street# frontage. #Buildings or other structures# which utilize the optional regulations of Section 23-143 applying to a #predominantly built-up area# shall be subject to the height and setback regulations for an R5B District. The provisions of this paragraph may be modified pursuant to paragraphs (h) and (j) of this Section.
- In the district indicated, no portion of a #building or other structure#, including the apex of a roof, may penetrate a plane 33 feet above the #base plane#. In addition, the maximum height of a #street wall# above the #base plane# shall be 30 feet. Above such height, no portion of the #building or other structure# shall penetrate a plane rising from the maximum #street wall# height, at 20 degrees to the horizontal, to a maximum height of 33 feet above the #base plane#. On #corner lots#, the 30 foot maximum #street wall# height shall apply to only one #street# frontage. The provisions of this paragraph may be modified pursuant to paragraph (h) of this Section.
- In the district indicated, no portion of a #building or other structure# shall penetrate a plane 40 feet above the #base plane#. However, where the ground floor level of a #building# provides a #qualifying ground floor# in accordance with the supplemental provisions set forth in paragraph (b)(2) of Section 23-662, the maximum height of a #building or other structure# may be increased to 45 feet, or four #stories#, whichever is less.
- In the districts indicated, a second #story# line-up is
required as follows:
Where at least 75 percent of the #buildings# containing #residences# within 150 feet of the #side lot lines# of the #zoning lot# have a first #story# front projection that is at least 50 percent of the width of the #building#, the #street wall# shall be no closer to the #street line# than the second #story street wall# of an adjacent #building# containing #residences# facing on the same #street#.
Projections from the first #story street wall# are permitted provided that such projections are no closer to the #street line# than an adjacent #front yard line#, and such projections are no higher than 13 feet above the #street wall line level#. Projections from the second #story street wall# are permitted provided that the width of all projections at that level does not exceed 33 percent of the width of the #building# at the second #story#, and the depth of the projections does not exceed three feet.
- The height and setback regulations of this Section are modified
as follows:
- In R3-1 and R3-2 Districts, #single-# or #two-family detached residences# on #zoning lots# of at least 9,500 square feet in area and at least 100 feet of frontage along a #street# may use the height and setback regulations applicable in an R2 District.
- In the #Special Ocean Parkway District#, the #Special
Coney Island Mixed Use District#, and the #Special Hunters
Point Mixed Use District#, for #buildings or other
structures# subject to the regulations of an R5 District
other than an R5D District, no portion of a #building or
other structure#, including the apex of a roof, may
penetrate a plane 40 feet above the #base plane#. In
addition, the maximum height of a #street wall# above the
#base plane# shall be 32 feet. Above such height, a
setback of 15 feet is required. Within the setback
distance, no portion of the #building or other structure#,
including the apex of a roof, may penetrate a plane rising
from the maximum #street wall# height at 20 degrees to the
horizontal. On #corner lots#, the 32 foot maximum #street
wall# height shall apply to only one #street# frontage.
In these special districts, for #developments# or #enlargements# which utilize the optional regulations applicable to a #predominantly built-up area#, the maximum height of a #building# containing #residences# shall not exceed 32 feet above the #base plane#. Furthermore, for such #developments# or #enlargements# with pitched roofs, the midpoint of such pitched roof shall not exceed a height of 32 feet above the #base plane#. The provisions of this paragraph may be modified pursuant to paragraph (j) of this Section. - In accordance with Section 78-31 (Location of Buildings, Distribution of Bulk and Open Space and Modification of Height and Setbacks), #buildings# within a #large-scale residential development# may use the alternate height and setback regulations set forth in paragraphs (b)(1) through (b)(3) of Section 78-31.
- In R3-2 Districts, #buildings# containing #affordable independent residences for seniors# may use the height and setback regulations applicable to an R4 District, as set forth in paragraph (b) of this Section.
- In R4 and R5 Districts, except R4-1, R4A, R4B, R5A, R5B and R5D
Districts, the height and setback provisions set forth in
paragraphs (b) and (d) of this Section shall apply to
#buildings# containing #affordable independent residences for
seniors#. However, where no #single-family# or #two-family
residence# existed on the #zoning lot# within three years prior
to the issuance of a building permit for the #development# or
#enlargement# of such #building# containing #affordable
independent residences for seniors#, such height and setback
provisions shall be modified as follows:
- in R4 Districts, the height of the #building# shall not exceed 45 feet; and
- in R5 Districts, the height of the #building# shall not
exceed 45 feet, except that beyond 25 feet of a #street
line#, the height of the #building# may be increased to a
height of 55 feet where one or more of the following
conditions are met:
- on the date of application for a building permit for such #development# or #enlargement#, not more than 50 percent of the aggregate length of the #block# frontage on both sides of the #street# facing each other is occupied by #single-family# or #two-family residences#;
- an existing #building# on the same or adjacent #zoning lot# of such #development# or #enlargement# has a height of 45 feet or more; or
- the #zoning lot# of such #development# or #enlargement# has a #lot area# of at least 1.5 acres.
- In the districts indicated, except R4-1, R4A, R4B, R5A, R5B and
R5D Districts, the City Planning Commission may authorize a
#building or other structure# that penetrates the height and
setback regulations set forth in paragraphs (b), (d) or (i) of
this Section, except for #buildings# utilizing the optional
regulations for #predominantly built-up areas#. As a condition
for granting such authorizations, the Commission shall find
that:
- by concentrating permitted #floor area# in a #building# or #buildings# of greater height, the preservation of an existing #building#, topography, vegetation, or view corridors having environmental, historic or aesthetic value to the public will be assured, and that such preservation would not be possible by careful siting of lower #buildings# containing the same permitted #floor area#; or, for #affordable independent residences for seniors#, the additional #floor area# permitted is accommodated in an efficient manner;
- such modification is the least modification required to achieve the purpose for which it is granted;
- the proposed modification does not impair the essential character of the surrounding area; and
- the proposed modification will not have adverse effects upon light, air, and privacy of adjacent properties and of any existing #buildings# on the #zoning lot#.
(3/22/16)
Side and rear setbacks shall be provided as specified in this Section. Permitted obstructions in required side and rear setbacks are set forth in paragraph (a) of this Section. Required side and rear setbacks for tall buildings in certain R1 through R5 Districts are set forth in paragraph (b) and required side and rear setbacks for #buildings# containing non-#residential uses# in certain R1 through R5 Districts are set forth in paragraph (c) of this Section.
- Permitted obstructions in required side and rear setbacks

hereinafter as a "base"), any portion or portions of a
#building# (referred to hereinafter as a "tower") shall
occupy in the aggregate:
- #Building# base regulations
- #Street wall# location
- On a #wide street#, and on a #narrow street# within
125 feet of its intersection with a #wide street#,
the #street wall# of the base shall occupy the
entire #street# frontage of a #zoning lot# not
occupied by existing #buildings#. At any height, at
least 70 percent of the width of such #street wall#
shall be located within eight feet of the #street
line#, and the remaining 30 percent of such #street
wall# may be recessed beyond eight feet of the
#street line# to provide #outer courts# or
balconies.
However, no such recesses shall be permitted within 20 feet of an adjacent #building# fronting on the same #street line# or within 30 feet of the intersection of two #street lines#. - On a #narrow street# beyond 125 feet from its intersection with a #wide street#, no #street wall# of a base is required nor shall any #street wall# provided beyond 125 feet count toward the computation of any permitted recesses on such wall.
- Where the #street wall# of an adjacent #building# fronting on the same #street line# is located within 10 feet of the #street line#, the #street wall# of the base shall be either located at the #street line# or aligned with the #street wall# of the adjacent #building# for a distance of not less than 20 feet measured horizontally from the side wall of such existing #building#.
- On a #wide street#, and on a #narrow street# within
125 feet of its intersection with a #wide street#,
the #street wall# of the base shall occupy the
entire #street# frontage of a #zoning lot# not
occupied by existing #buildings#. At any height, at
least 70 percent of the width of such #street wall#
shall be located within eight feet of the #street
line#, and the remaining 30 percent of such #street
wall# may be recessed beyond eight feet of the
#street line# to provide #outer courts# or
balconies.

- On a #wide street#, if the height of the #street
wall# of an adjacent #building# fronting on the same
#street line# exceeds 60 feet and if such #street
wall# is located within 10 feet of the #street
line#, the #street wall# of the base shall match the
height of the #street wall# of the adjacent
#building# to a maximum height of 100 feet by either
of three alternatives:
- the #street wall# of the base shall be extended vertically to the height of the adjacent #building# for a distance of not less than 20 feet measured horizontally from the side wall of such adjacent #building#;
- at least 50 percent of the width of the #street wall# of the base shall be extended vertically to the height of the adjacent #building#; or
- a dormer shall be provided pursuant to paragraph (b)(3) of this Section. Such dormer shall match the height of the adjacent #building#.
- On a #narrow street# beyond 100 feet of its intersection with a #wide street#, the #street wall# of a base shall rise vertically to a height of at least 60 feet when the adjacent #building# is either less than 60 feet or greater than 85 feet, or match the height of the adjacent #building# when the height of such #building# is between 60 feet and 85 feet.
- On a #wide street#, if the height of the #street
wall# of an adjacent #building# fronting on the same
#street line# exceeds 60 feet and if such #street
wall# is located within 10 feet of the #street
line#, the #street wall# of the base shall match the
height of the #street wall# of the adjacent
#building# to a maximum height of 100 feet by either
of three alternatives:
- #Street wall# location
- Dormer
For the purposes of this Section, a dormer shall be a vertical extension of the #street wall# of a base allowed as a permitted obstruction within a required front setback area. A dormer may be located anywhere on a #wide street#, and on a #narrow street# within 70 feet of its intersection with a #wide street#.
On any #street# frontage, the aggregate width of all dormers at the required initial setback level shall not exceed 60 percent of the width of the #street wall# of the highest #story# of the base. For each foot of height above the base, the aggregate width of all dormers at that height shall be decreased by one percent of the #street wall# width of the highest #story# of the base. Such dormer shall count as #floor area# but not as tower #lot coverage#. - Open areas
All open areas at ground level, located between the #street line# and the #street wall# of a base shall be landscaped except in front of entrances and exits to the #building#.
The tower #lot coverage# and #floor area# distribution requirements set forth in paragraph (a)(3) of this Section shall be modified for #buildings# that provide articulation of a base in accordance with the following provisions:
- Recesses
Recesses shall occupy, in the aggregate, between 30 and 50 percent of the width of each eligible #story# of the base, and measure at least two feet in depth. In addition, the width of any individual recess provided within eight feet of the #street line# shall not exceed 25 percent of the width of the #street wall# of the base, unless such recess is provided in combination with an additional recess located beyond eight feet of the #street line#.
Furthermore, all recesses shall comply with the provisions of paragraph (b)(1) of this Section or paragraph (a)(1) of Section 35-63 (Special Tower Regulations for Mixed Buildings), as applicable. For each #street# frontage of a #building# with recesses provided in accordance with this paragraph, (c)(1), the percent of #lot coverage# of the tower portion of the #building# may be decreased by 0.5 percent, and the minimum percent of total #building floor area# distribution below a level of 150 feet may be reduced by 0.25 percent. - Dormers
For each #street# frontage with dormers, provided in accordance with paragraph (b)(3) of this Section, that measure, at their lowest level, at least 50 percent of the width of the #street wall# of the highest #story# of the base, and measure, at their highest level, at least 25 percent of the width of the highest #story# of the base, and rise at least 25 feet above the base, the percent of #lot coverage# of the tower portion of the #building# may be decreased by 0.5 percent, and the minimum percent of total #building floor area# distribution below a level of 150 feet may be reduced by 0.25 percent. - Matching provision
For each #street# frontage that provides an extension of the #street wall# of a base that matches the height of an adjacent #building# in accordance with paragraph (b)(2)(i)(b) of this Section, the percent of #lot coverage# of the tower portion of the #building# may be decreased by 0.5 percent, and the minimum percent of total #building floor area# distribution below a level of 150 feet may be reduced by 0.25 percent.
(2/2/11)
Any #development# or #enlargement# that does not meet the location and #floor area# criteria of paragraph (a) of Section 23-65 and includes a tower shall be constructed as a standard tower in accordance with the regulations set forth in this Section.
At all levels, a tower shall be located not less than 15 feet from the #street line# of a #narrow street# and not less than 10 feet from the #street line# of a #wide street#.
Unenclosed balconies, subject to the provisions of Section 23-13 (Balconies), are permitted to project into or over open areas not occupied by towers.

- Setback requirements
For all #Quality Housing buildings#, a setback shall be provided in accordance with the following regulations:
- At a height not lower than the minimum base height or higher than the maximum base height specified for the applicable district in paragraph (b) of this Section, a setback with a depth of at least ten feet shall be provided from any #street wall# fronting on a #wide street#, and a setback with a depth of at least 15 feet shall be provided from any #street wall# fronting on a #narrow street#.
- The depth of such required setback may be reduced by one foot for every foot that the #street wall# is located beyond the #street line#, but in no event shall a setback of less than seven feet in depth be provided, except as otherwise set forth in this Section. To allow #street wall# articulation, where a #street wall# is divided into different segments and located at varying depths from the #street line#, such permitted setback reduction may be applied to each #street wall# portion separately.
- Notwithstanding the provisions of paragraph (c)(2) above, the depth of such setbacks may include the depth of recesses or #outer courts# in the #street wall# of the #building# base, provided that the aggregate width of any such recessed portion of a #street wall# with a setback less than seven feet, as applicable, does not exceed 30 percent of the #aggregate width of street wall# at any level.
- These setback provisions are optional for any #building# wall that either is located beyond 50 feet of a #street line#, or oriented so that lines drawn perpendicular to it, in plan, would intersect a #street line# at an angle of 65 degrees or less. In the case of an irregular #street line#, the line connecting the most extreme points of intersection shall be deemed to be the #street line#. Furthermore, dormers provided in accordance with the provisions of Section 23-621 (Permitted obstructions in certain districts) may penetrate a required setback area.
- In R9D Districts, for #buildings or other structures# on #zoning lots# that front upon an elevated rail line, at a height between grade level and 25 feet, a setback with a depth of at least 20 feet shall be provided from the #street line# fronting on such elevated rail line. The depth of such setback may be reduced by one foot for every foot that the depth of the #zoning lot#, measured perpendicular to the elevated rail line, is less than 110 feet, but in no event shall a setback less than ten feet in depth be provided.

In the districts indicated, any #Quality Housing building or other structure#, or portions thereof, which in the aggregate occupies not more than 40 percent of the #lot area# of a #zoning lot# (or, for #zoning lots# of less than 20,000 square feet, the percentage set forth in the table in Section 23-651 (Tower-on-a-base), above a height of 85 feet above the #base plane#, is hereinafter referred to as a tower. Dormers permitted within a required setback area pursuant to Section 23-621 (Permitted obstructions in certain districts) shall not be counted towards tower coverage. Such tower may exceed a height limit of 85 feet above the #base plane# provided the base of such tower complies with the applicable #street wall# location and height and setback provisions of Sections 23-661 and 23-662, respectively, and provided that the tower portion complies with the following, as applicable:
- at all levels, such tower shall be set back from the #street wall# of a base at least 15 feet along a #narrow street# and at least ten feet along a #wide street#, except such dimensions may include the depth of any permitted recesses in the #street wall#;
- the minimum coverage of such tower above a height of 85 feet above the #base plane# is at least 33 percent of the #lot area# of the #zoning lot#; however, such minimum coverage requirement shall not apply to the highest 40 feet of such tower;
- in R9D Districts, the highest four #stories#, or as many #stories# as are located entirely above a height of 165 feet, whichever is less, shall have a #lot coverage# of between 50 percent and 80 percent of the #story# immediately below such #stories#. Such reduced #lot coverage# shall be achieved by one or more setbacks on each face of the tower, where at least one setback on each tower face has a depth of at least four feet, and a width that, individually or in the aggregate, is equal to at least ten percent of the width of such respective tower face. For the purposes of this paragraph (c), each tower shall have four tower faces, with each face being the side of a rectangle within which the outermost walls of the highest #story# not subject to the reduced #lot coverage# provisions have been inscribed. The required setbacks shall be measured from the outermost walls of the #building#, perpendicular to each tower face. Required setback areas may overlap; and
- in R9D Districts, for towers fronting on elevated rail lines, the outermost walls of each #story# located entirely above a height of 85 feet shall be inscribed within a rectangle. The maximum length of any side of such rectangle that is parallel to, or within 45 degrees of being parallel to, such elevated rail line shall be 125 feet, or 75 percent of the frontage of the #zoning lot# along such elevated rail line, whichever is less.
