Upon its completion, the Equitable Building was controversial because of its lack of setbacks, which in turn does not allow sunlight to reach the surrounding ground. This contributed to the adoption of the first modern building and zoning restrictions on vertical structures in Manhattan, the 1916 Zoning Resolution. The building was designated a National Historic Landmark in 1978 and was designated a city landmark by the New York City Landmarks Preservation Commission in 1996. It is also a contributing property to the Wall Street Historic District, a NRHP district created in 2007.
