In Subdistrict A-1, the underlying height and setback regulations set forth in Sections 43-43 (Maximum Height of Front Wall and Required Front Setbacks) and 43-44 (Alternate Front Setbacks) shall not apply. In lieu thereof, the following provisions shall apply:
- #Street wall# location
The #street wall# of any #building# shall be located on the #street line# and extend along the entire #street# frontage of the #zoning lot# up to at least the maximum base height specified in paragraph (b) of this Section. On the ground floor, recesses shall be permitted where required to provide access to the #building#, provided such recesses do not exceed three feet in depth as measured from the #street line#. In addition, the #street wall# location provision of this paragraph shall not apply along such #street line# occupied by a #public plaza# as set forth in Section 37-70 (PUBLIC PLAZAS). - Base height
- Along #wide streets#
On #wide streets#, and on #narrow streets# within 50 feet of their intersection with a #wide street#, the #street wall# of a #building# shall rise without setback to a minimum base height of 125 feet and may rise to a maximum base height of 155 feet.
However, where the height of an existing adjacent #street wall# fronting on the same #street line# rises to a height exceeding 155 feet before setback, the maximum base height may be increased to the height of such existing adjacent #street wall# but shall not exceed a base height of 205 feet. In addition, where existing adjacent #street walls# on both sides of the #building# rise to a height exceeding 155 feet before setback, the maximum base height of such #building# may be increased to the higher of the two existing adjacent #street walls#, except in no instance shall the base height of such #building# exceed 205 feet. - Along #narrow streets#
On #narrow streets#, beyond 50 feet of their intersection with a #wide street#, the #street wall# of a #building# shall rise without setback to a minimum base height of 85 feet and may rise to a maximum base height of 135 feet.
As an alternative, the minimum and maximum base heights applicable to a #wide street# may be applied along a #narrow street# beyond 50 feet of a #wide street#, up to a maximum of 100 feet from such #wide street#.

- Along #wide streets#
For #buildings#, or portions thereof, located on #wide streets# and on #narrow streets# within 100 feet of a #wide street#, the portion of such #building# above the applicable maximum base height set forth in paragraph (b)(1) of this Section, shall be set back from the #street wall# of the #building# at least 10 feet along a #wide street# and at least 15 feet along a #narrow street#, except such dimensions may include the depth of any permitted recesses in the #street wall#. Above such required setback, any portion of a #building# on the #zoning lot# shall be considered a “tower.” - Along #narrow streets#
For #buildings#, or portions thereof, located on #narrow streets# beyond 100 feet of a #wide street#, the portion of such #building# above the applicable maximum base height set forth in paragraph (b)(2) of this Section shall be set back from the #street wall# of the #building# at least 15 feet along a #narrow street#, except such dimensions may include the depth of any permitted recesses in the #street wall#. Above such required setback, any portion of a #building# on the #zoning lot# shall be considered a “tower.”

Each #story# of a tower above the required setback shall not exceed a maximum #lot coverage# of 40 percent of the #lot area# of a #zoning lot# or, for #zoning lots# of less than 20,000 square feet, the percent set forth in Section 43-451 (Towers on small lots). - Maximum #building# height
No height limit shall apply to towers.
