1961 Zoning Resolution

Legacy

The New York City Department of City Planning passed the 1961 Zoning Resolution in October 1960, and the new zoning rules became effective in December 1961, superseding the 1916 Zoning Resolution. The new zoning solution used the Floor Area Ratio (FAR) regulation instead of setback rules. A building's maximum floor area is regulated according to the ratio that was imposed to the site where the building is located. Another feature of new zoning solution was adjacent public open space. If developers put adjacent public open space to their buildings, they could get additional area for their building as a bonus. This incentive bonus rule was created because of the strong influence from two representative skyscrapers. The Seagram Building by Mies van der Rohe with Philip Johnson, and Lever House by Skidmore, Owings & Merrill, introduced the new ideas about office building with open space. These buildings changed the skyline of New York City with both the advent of simple glass box design and their treatment of adjacent open spaces. The new zoning encouraged privately owned public space to ease the density of the city.
