IH

Inclusionary Housing is the umbrella for New York City's programs tying floor area to affordable housing. Since the City of Yes for Housing Opportunity amendment took effect on December 5, 2024, it has two parts. In mapped Mandatory Inclusionary Housing areas, affordable housing is a requirement of new residential floor area (§ 27-131). Outside them, in the residence districts whose floor area § 23-22 sets and commercial districts using their rules, the Universal Affordability Preference lets a development exceed the floor area set there for standard residences by the affordable housing it provides (§ 27-111). The Preference replaced the older voluntary program, whose bonus rules sat in the former § 23-154; both programs are now administered under Article II, Chapter 7 of the Zoning Resolution.

Because participation is optional, the voluntary program operates where the bonus economics work. It coexists with MIH: one is an offer, the other a mapped requirement, and a given lot may be subject to either, both frameworks in different respects, or neither.
