Developers were using excessive mechanical spaces to increase the height of their buildings. On May 29, 2019, the City Council voted to adopt the Residential Tower Mechanical Voids Text Amendment with modifications. The Department of City Planning proposed the amendment in response to developers incorporating excessively tall mechanical floors – “mechanical voids” – in residential towers to increase their allowable height, as mechanical floors did not count toward the zoning floor area in the Zoning Resolution. This would result in towers with several floors of mostly empty space that would allow developers to build higher, increasing the values of the apartments on higher floors. In late 2018, Mayor Bill de Blasio asked the Department of City Planning (DCP) to investigate the mechanical voids problem and find a solution.
