On May 29, 2019, the City Council adopted a zoning text
amendment to count certain mechanical voids as zoning floor area in
residential towers.
The amendment does not prohibit any mechanical space outright;
instead, it requires that mechanical floors exceeding a height of
25 feet be counted as zoning floor area. Additionally, such
mechanical floors will count toward zoning floor area if they are
located within 75 feet of one another and exceed 25 feet in height
in the aggregate. Above the 25-foot threshold, the number of
stories of floor area is calculated by aggregating the total height
of such spaces, dividing by 25 and rounding to the nearest whole
integer. For example, a 40-foot mechanical void would count as two
floors of floor area (40/25 = 1.6, rounded to the closest whole
number equals two).
