New York City aims to spur construction of more accessory dwelling units (ADUs)

To address a serious housing shortage, New York City is trying to get more homeowners to build accessory dwelling units (ADUs).

The city recently unveiled a program that offers owners of single-family homes up to nearly $400,000 to construct an apartment on their property. The program is modest in scope, limiting the number of grants to 15 homeowners, but the city hopes it will create momentum for building more granny flats.

The mayor’s administration is also backing zoning changes to allow homeowners in more parts of the city to add ADUs. Previous government initiatives to modify regulations and encourage development of ADUs have largely failed, according to a report in the New York Times. Suburban legislators helped stymie Gov. Kathy Hochul’s attempt this year to ease some restrictions, the Times reported.

Although many people conceive of New York as a high-density area, lower-density neighborhoods make up more than half of the city’s land. These neighborhoods can accommodate many ADUs.

New York City has two very large buildings dedicated to answering the 911 calls of its five boroughs. With more than 11 million emergency calls annually, it makes perfect sense. The second of these buildings, the Public Safety Answering Center II (PSAC II) is located on a nine-acre parcel of land in the Bronx. It’s an imposing 450,000 square-foot structure—a 240-foot-wide by 240-foot-tall cube. The gleaming aluminum cube risesthe equivalent of 24 stories from behind a grassy berm, projecting the unlikely impression that it might actually be floating. Like most visually striking structures, the building has drawn as much scorn as it has admiration.
