23-423 - Standard setback regulations LAST AMENDED 12/5/2024 Where minimum setback regulations are specific for a particular #building# envelope for a particular district, the following shall apply. At a height not higher than the maximum base height specified for the applicable district, a setback with a depth of at least 10 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#. Such minimum setbacks may be modified as follows: (a) The depth of such required setback may be reduced by one foot for every foot that the #street wall# is located beyond the minimum required #front yard#, 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. (b) 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. (c) 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#. (d) Dormers provided in accordance with the provisions of Section 23-413 (Permitted obstructions in certain districts) may penetrate a required setback area.
