SEC. 263.20. SPECIAL HEIGHT EXCEPTION: ADDITIONAL FIVE FEET HEIGHT FOR ACTIVE GROUND FLOOR USES IN CERTAIN DISTRICTS AND ALL GROUND
FLOOR USES IN THE R-4 HEIGHT AND BULK DISTRICT.
(a) Intent. In order to encourage generous ground floor ceiling heights for commercial and other active uses, encourage additional light and air into ground floor spaces, allow for walk-
up ground floor residential uses to be raised slightly from sidewalk level for privacy and usability of front stoops, and create better building frontage on the public street, up to an additional
5' of height is allowed along major streets in NCT districts, or in specific districts listed below, for buildings that feature either higher ground floor ceilings for non-residential uses or
ground floor residential units (that have direct walk-up access from the sidewalk) raised up from sidewalk level.
(b) Applicability. The special height exception described in this Section 263.20 shall only apply to projects that meet both of the following criteria:
(1) project is located in a 30-X, 40-X, or 50-X Height and Bulk District, or in the R-4 Height and Bulk District with a height limit of 40, 50, or 80 feet, as designated on the Zoning
Map;
(2) project features ground floor commercial space or other active use as defined by Section 145.1(b)(2) with clear ceiling heights in excess of ten feet from sidewalk grade, or in the
case of residential uses, such walk-up residential units are raised up from sidewalk level.
(c) One additional foot of height, up to a total of five feet, shall be permitted above the designated height limit for each additional foot of ground floor clear ceiling height in excess of 10
feet from sidewalk grade, or in the case of residential units, for each foot the unit is raised above sidewalk grade.

Editor's Notes:
Ordinance 72-08, approved 4/30/2008, enacted new sections designated 263.18 and 263.20. The editor redesignated those two sections as this Sec. 263.20 and Sec. 263.22, respectively.
This section subsequently has been amended under its current number by multiple ordinances, as documented in the history note above.
After the addition of this section to the Code, Ord. 200-08, approved 8/22/2008, enacted a new section with the same number as this section. That new section was redesignated and codified as Sec. 263.23 by the editor.
