Inclusionary Housing Program

The Inclusionary Housing Program (IHP) is designed to preserve and promote affordable housing within neighborhoods where zoning has been modified to encourage new development. The IHP consists of two programs:

Voluntary Inclusionary Housing (VIH), enacted in 1987, where applicable, enables a development to receive a density bonus in return for the new construction, substantial rehabilitation, or preservation of permanently affordable housing.

Mandatory Inclusionary Housing (MIH), enacted in March 2016, requires a share of new housing in medium- and high-density areas that are rezoned to promote new housing production—whether rezoned as part of a city neighborhood plan or a private rezoning application—to be permanently affordable.  

HPD is proposing amendments to Chapter 41 of Title 28 of the Rules of the City of New York (the "Inclusionary Housing Rules") to limit the zoning bonus generated by 421-a affordable units to usage on the same zoning lot as the building containing the 421-a affordable units. HPD will hold a public hearing on Monday, August 7, 2017, about the proposed rule amendment. For more details, clickh here:

The Inclusionary Housing Map, is being released now to provide information to the public. The map allows users to locate Inclusionary Housing (IH) projects, which are called generating sites and contain permanently affordable IH apartments. The map also displays the sites that have received IH floor area from generating sites; these are called compensated developments.

To see the relationship between a specific generating site and its compensated sites, search using the Query by Generating Project Name function. The map will simultaneously highlight a generating site and its compensated development(s) with a blue box.

Users can also search or query by City Council District (CD) to see all the IH production in the CD, or, for information about a specific project, query by address or by BBL (Borough, Block and Lot). Users can also see the balance of floor area remaining at a generating site just by clicking on the site. The layers tool lets users see information such as the city’s zoning districts and community boards. Please note the source of most layers is the NYC Department of City Planning (DCP), not HPD.

The map will be updated monthly. As of October 2016, only Voluntary Inclusionary Housing (VIH) projects are mapped. Once Mandatory Inclusionary Housing (MIH) projects are approved, those will be mapped as well.
